for approx. 10 seconds during the sys- tem self-check after turning key in the steering lock to position 2 (together with the SOS button and the Roadside Assistance button •). See system self-check (컄 page 172) when the indicator lamp does not light up in red or stays on longer than ap- proximately ten seconds. If the indicator lamp in the Information button ¡ is illuminated continuous- ly and there was no voice connection to the Response Center established, then the Tele Aid system could not initiate an Information call (e.g. the relevant cellular phone network is not avail- able).

178

The message INFO CALL FAILED ap- pears in the MCS display. Information calls can be terminated us- ing the END button on the MCS.

If the indicator lamps do not start flash- ing after pressing one of the buttons or remains illuminated (in red) at any time, the Tele Aid system has detected a fault or the service is not currently ac- tive, and may not initiate a call. Visit your Mercedes-Benz Light Truck Cen- ter and have the system checked or contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada) as soon as possible.

Upgrade signals The Tele Aid system processes calls using the following priority. 앫 Automatic emergency – First priority 앫 Manual emergency – Second priority 앫 Roadside assistance – Third priority 앫 Information – Fourth priority Should a higher priority call be initiated while you are connected, an upgrade (al- ternating) tone will be heard and the ap- propriate indicator lamp will flash. If certain information such as vehicle identi- fication number or customer information is not available, the operator may need to re- transmit. During this time you will hear a beep and voice contact will be interrupted. Voice contact will resume once the retransmis- sion is completed. Once a call is conclud- ed, a beep will be heard and the respective indicator lamp will stop flashing. The MCS system operation will resume.

i When a Tele Aid call has been initiated, the MCS system audio is muted and the selected mode (radio, tape or CD) pauses. The optional cellular phone (if installed) switches off. If you must use this phone, the vehicle must be parked. Disconnect the coiled cord and place the call. The navigation system (if en- gaged) will continue to run. A pop-up window will appear in the MCS display to indicate that a Tele Aid call is in progress.

If the indicator lamp continues to flash or the system does not reset, contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada), or Mercedes-Benz Customer Assistance at 1-800-FOR-MERCedes (1-800-367-6372) in the USA or Cus- tomer Service at 1-800-387-0100 in Canada.

The indicator lamp on the correspond- ing button flashes until the call is con- cluded. Calls can only be terminated by a Response Center or Customer Assis- tance Center representative, except Roadside Assistance and Information calls, which can also be terminated by using the END button on the MCS unit.

Warning!

Before programming the integrated remote control to a garage door opener or gate op- erator, make sure that people and objects are out of the way of the device to prevent potential harm or damage.

When programming a garage door opener, the door moves up or down. When program- ming a gate operator, the gate opens or closes.

Do not use the integrated remote control with any garage door opener that lacks safe- ty stop and reverse features as required by U.S. federal safety standards (this includes any garage door opener model manufac- tured before April 1, 1982). A garage door that cannot detect an object - signaling the door to stop and reverse - does not meet current U.S. federal safety standards.

Controls in detail Useful features

Certain types of garage door openers are incompatible with the integrated opener. If you should experience diffi- culties with programming the transmit- ter, contact your authorized Mercedes-Benz Light Truck Center, or call Mercedes-Benz Customer Assis- tance Center (in the USA only) at 1-800-FOR-MERCedes, or Customer Service (in Canada) at 1-800-387-0100.

Programming or reprogramming the in- tegrated remote control Step 1: 왘 Switch on ignition. Step 2: 왘 If you have previously programmed an

integrated signal transmitter button and wish to retain its programming, proceed to step 3. Otherwise, press and hold the two outer signal transmit- ter buttons 3 and 5 and release them only when the indicator light be- gins to flash after approximately 20 seconds (do not hold the button for longer than 30 seconds). This proce- dure erases any previous settings for all three channels and initializes the memory. If you later wish to program a second and/or third hand-held trans- mitter to the remaining two signal transmitter buttons, do not repeat this step and begin directly with step 3.

Step 3: 왘 Hold the end of the hand-held remote

control transmitter 1 of the device you wish to train approximately 2 to 5 in (5 to12 cm) away from the surface of the integrated remote control locat- ed on the interior rear view mirror, keeping the indicator lamp 6 in view.

Step 4: 왘 Using both hands, simultaneously

press the hand-held transmitter button 2 and the desired integrated signal transmitter button (3, 4 or 5). Do not release the buttons until completing step 5. The indicator lamp 6 on the integrat- ed remote control will flash, first slowly and then rapidly.

i The indicator lamp 6 flashes the first time the signal transmitter button is programmed. If this button has already been programmed, the indicator lamp will only start flashing after 20 sec- onds.

If the indicator lamp 6 flashes rapidly for about two seconds and then turns to a constant light, continue with pro- gramming steps 8 through 12 as your garage door opener may be equipped with the “rolling code” feature.

Step 7: 왘 To program the remaining two buttons,

repeat the steps above starting with step 3.

Step 5: 왘 When the indicator lamp 6 flashes

rapidly, release both buttons.

Step 6: 왘 Press and hold the just-trained inte- grated signal transmitter button and observe the indicator lamp 6. If the indicator lamp 6 stays on con- stantly, programming is complete and your device should activate when the integrated signal transmitter button is pressed and released.

Rolling code programming To train a garage door opener (or other roll- ing code devices) with the rolling code fea- ture, follow these instructions after completing the “Programming” portion (steps 1 through 6) of this text. (A second person may make the following training procedures quicker and easier.) Step 8: 왘 Locate “training” button on the garage

door opener motor head unit. Exact location and color of the button may vary by garage door opener brand. Depending on manufacturer, the “train- ing” button may also be referred to as “learn”or “smart” button. If there is dif- ficulty locating the transmitting button, refer to the garage door opener opera- tor’s manual.

Step 12: 왘 Confirm the garage door operation by pressing the programmed integrated signal transmitter button (3, 4 or 5).

Step 13: 왘 To program the remaining two buttons,

repeat the steps above starting with step 3.

Gate operator/Canadian programming Canadian radio-frequency laws require transmitter signals to “time-out” (or quit) after several seconds of transmission which may not be long enough for the inte- grated signal transmitter to pick up the sig- nal during programming. Similar to this Canadian law, some U.S. gate operators are designed to “time-out” in the same manner. If you live in Canada or if you are having dif- ficulties programming a gate operator (re- gardless of where you live) by using the programming procedures, replace step 4 with the following:

Erasing the remote control memory 왘 Switch on ignition. 왘 Simultaneously hold down the signal transmitter buttons 3 and 5, for ap- proximately 20 seconds, or until the in- dicator lamp 6 flashes rapidly. Do not hold for longer than 30 seconds. The codes of all three channels are erased.

If you sell your vehicle, erase the codes of all three channels.

Reprogramming a single integrated signal transmitter button To program a device using a signal trans- mitter button previously trained, follow these steps: 왘 Press and hold the desired signal trans- mitter button (3, 4 or 5). Do not re- lease the button.

왘 The indicator lamp will begin to flash af- ter 20 seconds. Without releasing the integrated signal transmitter button, proceed with programming starting with step 3.

Step 4: 왘 Continue to press and hold the inte- grated signal transmitter button (3, 4 or 5) while you press and re-press (“cycle”) your hand-held remote con- trol transmitter 1 every two seconds until the frequency signal has been learned. Upon successful training, the indicator lamp 6 will flash slowly and then rapidly after several seconds.

왘 Proceed with programming step 5 and

step 6 to complete.

Operation of remote control 왘 Switch on ignition. 왘 Select and press the appropriate inte- grated signal transmitter button (3, 4 or 5 to activate the remote con- trolled device.

Operation The first 1000 miles (1500 km)

In the “Operation” section you will find de- tailed information on operating, maintain- ing and caring for your vehicle.

After 1000 miles (1500 km) you may grad- ually increase vehicle and engine speeds to the permissible maximum. All of the above instructions, as may apply to your vehicle type, also apply when the first 1000 miles (1500 km) after the en- gine, the transfer case, the front differen- tial or the rear differential has been replaced.

Always obey applicable speed limits.

왔

The first 1000 miles (1500 km) The more cautiously you treat your vehicle during the break-in period, the more satis- fied you will be with its performance later on. 앫 Drive your vehicle during the first

1000 miles (1500 km) at varying but moderate vehicle and engine speeds. 앫 During this period, avoid heavy loads (full throttle driving) and excessive en- gine speeds (no more than 2/3 of max- imum rpm in each gear).

앫 Avoid accelerating by kick-down. 앫 Do not attempt to slow the vehicle

down by shifting to a lower gear using the gear selector lever.

앫 Select positions 3, 2 or 1 only when driving at moderate speeds (for hill driving).

Operation Driving instructions

Drinking and driving

Pedals

Warning!

Warning!

Drinking and driving and/or taking drugs and driving are a very dangerous combina- tion. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgement.

The possibility of a serious or even fatal ac- cident are greatly increased when you drink or take drugs and drive.

Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs.

Keep driver’s foot area clear at all times. Ob- jects stored in this area may impair pedal movement.

Power assistance

Warning!

With the engine is not running, there is no power assistance for the brake and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the ve- hicle.

왔 Driving instructions Drive sensibly – save fuel

Fuel consumption, to a great extent, de- pends on driving habits and operating con- ditions. To save fuel you should: 앫 Keep tires at the recommended infla-

tion pressures

앫 Remove unnecessary loads 앫 Allow engine to warm up under low

load use

앫 Avoid frequent acceleration and decel-

eration

앫 Have all maintenance work performed at the intervals specified in the Service Booklet and as required by the FSS. Contact your authorized Mercedes-Benz Light Truck Center

Fuel consumption is also increased by driv- ing in cold weather, in stop-and-go traffic, on short trips and in hilly country.

193

Operation Driving instructions

Brakes

Warning!

After driving in heavy rain for some time without applying the brakes or through wa- ter deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary to obtain expected braking ef- fect. Maintain a safe distance from vehicles in front.

194

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.

It can also result in the brakes overheating, thereby significantly reducing their effec- tiveness. It may not be possible to stop the vehicle in sufficient time to avoid an acci- dent.

To help prevent brake disk corrosion after driving on wet road surfaces (particularly salted roads), it is advisable to brake the vehicle with considerable force prior to parking. The heat generated serves to dry the brakes. If your brake system is normally only sub- jected to moderate loads, you should occa- sionally test the effectiveness of the brakes by applying above-normal braking pressure at higher speeds. This will also enhance the grip of the brake pads.

Be very careful not to endanger other road users when you apply the brakes. Refer to the description of the Brake Assist System (BAS) (컄 page 78).

If the parking brake is released and the brake warning lamp in the instrument clus- ter stays on and there is no audible warn- ing (EBP), the brake fluid level in the reservoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the res- ervoir. Have the brake system inspected immedi- ately. Contact your authorized Mercedes-Benz Light Truck Center. All checks and service work on the brake system should be carried out by qualified technicians only. Contact your authorized Mercedes-Benz Light Truck Center.

Install only brake pads and brake fluid recommended by Mercedes-Benz.

Warning!

If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident.

When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear to use the engine’s braking power. This helps prevent overheating of the brakes and reduces brake pad wear.

After hard braking, it is advisable to drive on for some time, rather than immediately parking, so the air stream will cool down the brakes faster.

Operation Driving instructions

Driving off

Apply the brakes to test them briefly after driving off. Perform this procedure only when the road is clear of other traffic. Warm up the engine smoothly. Do not place full load on the engine until the oper- ating temperature has been reached. When starting off on a slippery surface, do not allow a drive wheel to spin for an ex- tended period with the ESP switched off. Doing so may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

195

Operation Driving instructions

Parking

Set the parking brake whenever park- ing or leaving the vehicle. In addition, move gear selector lever to position P. When parking on hills, always turn front wheels towards the curb.

196

Warning!

Tires

To reduce the risk of personal injury, or damage to the vehicle powertrain, as a re- sult of vehicle/ trailer movement, always: 앫 Keep right foot on brake pedal. 앫 Shift gear selector lever to position N. 앫 Have a second person place wheel

chocks on downhill side of left and right trailer wheels.

앫 Slowly release brake pedal and let vehi-

cle and trailer roll into chocks until stopped.

앫 Firmly depress parking brake pedal. 앫 Move gear selector lever to position P. 앫 When parked on an incline, turn front

wheel towards the road curb.

Warning!

If you feel a sudden significant vibration or ride disturbance, or you suspect that possi- ble damage to your vehicle has occurred, you should turn on the hazard warning flash- ers, carefully slow down, and drive with cau- tion to an area which is a safe distance from the road.

Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz Light Truck Center or tire dealer for repairs.

Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and be- come visible at a tread depth of approxi- mately 1/16 in (1.6 mm), at which point the tire is considered worn and should be replaced.

The tread wear indicator appears as a solid band across the tread.

Warning!

Warning!

Although the applicable federal motor vehi- cle safety laws consider a tire to be worn when the tread wear indicators (TWI) be- come visible at approximately 1/16 in (1.6 mm), we recommend that you do not al- low your tires to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Specified tire pressures must be main- tained. This applies particularly if the tires are subjected to high loads (e.g. high speeds, heavy loads, high ambient temper- atures).

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build-up and possibly a fire.

Hydroplaning

Depending on the depth of the water on the road, hydroplaning may occur even at low speeds and with new tires. Reduce ve- hicle speed, avoid track grooves in the road and apply brakes cautiously in the rain.

Tire traction

The safe speed on a wet, snow covered or icy road is always lower than on a dry road.

Operation Driving instructions

You should pay particular attention to the condition of the road whenever the outside temperatures are close to the freezing point.

Warning!

If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

Mercedes-Benz recommends M+S rated radial-ply tires with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season to ensure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance as compared with sum- mer tires. Stopping distance, however, is still consid- erably greater than when the road is not covered with snow or ice. Exercise appro- priate caution.

197

Operation Driving instructions

Avoid spinning of one drive wheel. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

Tire speed rating

Regardless of the tire speed rating, local speed limits should be obeyed. Use pru- dent driving speeds appropriate to prevail- ing conditions.

Warning!

Even when permitted by law, never operate a vehicle at speeds greater than the maxi- mum speed rating of the tires.

Exceeding the maximum speed for which tires are rated can lead to sudden tire fail- ure, causing loss of vehicle control and pos- sibly resulting in an accident and/or serious injury and possible death, for you and for others.

198

ML 350
Your vehicle is factory equipped with “H”-rated tires, which have a speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h). ML 500
Your vehicle is factory equipped with “V”-rated tires, which have a speed rating of 149 mph (240 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

Winter driving instructions

The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, move gear selector lever to position N. Try to keep the vehicle under control by cor- rective steering action.

For information on driving with snow chains, see “Snow chains” (컄 page 231).

For information on speed ratings for winter tires, see “Winter tires” (컄 page 230).

Warning!

On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehi- cle control. Your vehicle’s ABS will not pre- vent this type of control loss.

Do not engage the transfer case in position LOW when driving on ice or packed snow. At speeds below 18 mph (30 km / h) vehicle steering is adversely affected by the LOW RANGE - ABS (컄 page 77).

Road salts and chemicals can adversely af- fect braking efficiency. Increased pedal force may become necessary to produce the normal brake effect. Depressing the brake pedal periodically when traveling at length on salt-strewn roads can bring road-salt-impaired braking efficiency back to normal.

If the vehicle is parked after being driven on salt-treated roads, the braking efficien- cy should be tested as soon as possible af- ter driving is resumed.

Warning!

Make sure not to endanger any other road users when carrying out these braking ma- neuvers.

Warning!

If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with the engine running. Otherwise, deadly carbon monoxide (CO) gases may enter vehicle in- terior resulting in unconsciousness and death.

To assure sufficient fresh air ventilation, open a window slightly on the side of the ve- hicle not facing the wind.

Operation Driving instructions

Warning!

The outside temperature indicator is not de- signed to serve as an ice-warning device and is therefore unsuitable for that purpose. In- dicated temperatures just above the freez- ing point do not guarantee that the road surface is free of ice.

For more information, see "Winter driving" (컄 page 230).

Operation Driving instructions

Standing water

Off-road driving

Do not drive through flooded areas or water of unknown depth. Before driving through water, determine its depth. Never accelerate before driving into water. The bow wave could force water into the engine and auxiliary equip- ment, thus damaging them. If you must drive through standing wa- ter, drive slowly to prevent water from entering the passenger compartment or the engine compartment. Water in these areas could cause damage to electrical components or wiring of the engine or transmission, or could result in water being ingested by the engine through the air intake, causing severe internal engine damage. Any such dam- age is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Drive slowly in unknown terrain. This will make it easier to recognize unexpected ob- stacles and avoid damage to the vehicle.

To help avoid the vehicle rolling over, never turn it around on steep inclines. If the vehi- cle cannot complete the attempted climb, back it down in reverse gear.

Do not drive along the side of a slope (dan- ger of vehicle rollover). The vehicle might otherwise rollover. If in doing so the vehicle begins to show a tendency to roll, immedi- ately steer into a line of gravity (straight up or downhill).

Never let the vehicle roll backwards in idle. You may lose control of the vehicle if you use only the service brake.

200

Warning!

Sand, dirt, mud and other material having friction property can cause exceptional wear and tear as well as brake failure.

Have the brakes checked for dirt build-up and cleaned. There is otherwise a risk that full braking power may not be available in an emergency.

Read this chapter carefully before you be- gin off-road travel. Familiarize yourself with the vehicle char- acteristics and gear changing before you attempt any difficult terrain off-road driv- ing. We recommend that you start out with easy off-road travel.

Special driving features for off-road driving The following driving features are available for specific kind of operation: 앫 LOW RANGE mode (컄 page 125) 앫 LOW RANGE – ABS (컄 page 77) 앫 LOW RANGE – 4-ETS (컄 page 80) 앫 LOW RANGE – ESP (컄 page 81)

Off-road driving rules Engage the LOW RANGE mode before driv- ing under off-road conditions (컄 page 125). Fasten items being carried as securely as possible (컄 page 157).

We recommend keeping doors, liftgate, windows, and sliding/pop-up roof* closed whenever driving in off-road mode.

Observe the following during off-road driving: 앫 Adjust vehicle speed to condition of terrain. The more uneven, rutty and steeper the terrain, the lower the speed should be

앫 Watch out for obstacles, such as rocks, holes, tree stumps and ruts. 앫 Be especially careful when driving in unknown territory. It may be nec- essary to get out of the vehicle and scout the path you intend to take. 앫 Before driving through water, deter-

mine is depth.

앫 Do not stop vehicle while immersed

in water, and do not shut off the engine.

Operation Driving instructions

앫 In sandy soil, please drive at a

steady speed as allowed by condi- tions. This helps overcome the vehi- cle rolling resistance and reduces the likelihood of the vehicle sinking into the ground.

앫 Do not initiate jumps with the vehi-

cle. It interrupts the forward mo- mentum of the vehicle.

앫 Always drive onto slopes with the the engine running and the vehicle in gear.

Checklist before off-road driving

Tires 앫 Check the tread depth and maintain specified tire pressure (see tire pres- sure label inside the fuel filler flap).

앫 Check tires for possible damage and

remove foreign objects.

앫 Replace missing valve caps.

201

Operation Driving instructions

Rims 앫 Dented or bent rims can cause tire pressure loss and damage the tire beads. For this reason, check and, if necessary, change rims before driving off-road.

Vehicle tool kit 앫 Check if the vehicle jack is functional. 앫 In all cases take the vehicle tool kit, a strong tow rope, a shovel and a small plank (to put under the vehicle jack on sandy soil) with you.

Driving in steep terrain

202

Slope angle 1 25° 2 26° 앫 Switch to LOW RANGE mode before starting to drive up or down steep in- clines (컄 page 125).

앫 Driving on embankments, slopes and

other steep inclines should only be done straight up or downhill, i.e. in the line of gravity. Maximum vehicle climb- ing ability is a 60% grade.

앫 Do not drive along the side of a slope (danger of vehicle rollover). If in doing so, the vehicle begins to show a ten- dency to roll, immediately steer into a line of gravity (straight up or downhill). 앫 To help avoid the vehicle rolling over, never turn it around on steep inclines. If the vehicle cannot complete the at- tempted climb, back it down in reverse gear.

앫 Utilize the engine’s braking power

when descending a slope, observe the engine speed (do not overview the en- gine). Apply the service brake as need- ed.

앫 Check the brakes after a lengthy down-

grade drive.

Avoid excessive engine speeds – drive with moderate engine speeds (max. 3000 RPM). Select gear range 2 or 1 on the auto- matic transmission (컄 page 121).

Traction in steep terrain 앫 Be easy on the accelerator and watch

for continuous wheel traction when driving in steep terrain. The 4-ETS helps greatly when starting out on a steep incline when the front wheels have then the tendency to slip due to the weight shifting away the front axle.

The 4-ETS recognizes the situation and limits the torque for the front wheels by braking them. Simultaneously the torque for the rear wheels is increased.

Driving across a hilltop 앫 Decelerate just ahead of a hilltop (do not select gear range N), to prevent the vehicle from speeding up too much af- ter climbing a hill. Use the momentum of the vehicle to drive across the hilltop. Driving in this manner prevents the ve- hicle from jumping across the hilltop and thus loosing its forward momen- tum.

Driving downhill 앫 Select gear range 1 on the automatic

transmission (컄 page 121).

앫 Drive downhill observing the same rules as driving uphill (컄 page 202).

앫 The special LOW RANGE – ABS setting

allows for precise and brief (cyclical) blocking of the front wheels, permitting them to dig into loose ground. Remember that the front wheels when stopped, slide across a surface, thus loose their ability to steer the vehicle.

Operation Driving instructions

Driving through water

1 20 in (50 cm) 앫 Before driving through water, deter-

mine its depth. It should not be deeper than approxi- mately 20 inches (50 cm). Make sure you check the water bed. The ground surface may not be firm which may result in deeper waters than expected when driving the vehicle through it.

앫 Switch to LOW RANGE mode before driving through water (컄 page 125).

203

Operation Driving instructions

앫 Switch off the exterior lamps as well as

the climate control.

앫 Select gear range 1 on the automatic

transmission (컄 page 121).

앫 Enter the water only at a shallow spot,

driving at walking speed.

Never accelerate before driving into the water. The bow wave could force water into the engine and auxiliary equipment, thus damaging them.

앫 Do not stop vehicle while immersed in water, and do not shut off the engine. There is a very high level of driving re- sistance in water. The surface is slip- pery and may not be firm, making pulling away in water difficult and dan- gerous.

앫 Clean mud off the tire tread after driv-

ing through water.

204

앫 To dry the brakes, apply pressure to the brake pedal several times after leaving the water.

Crossing obstacles

Obstacles can damage the vehicle undercarriage or suspension compo- nents. If possible use the assistance of a second person outside the vehicle to scout the path you intend to take and check for adequate ground clearance when you cross obstacles with your ve- hicle. The person assisting you outside the vehicle should always be a safe dis- tance away from the vehicle and posi- tioned so that he or she cannot get hurt in case of any unexpected vehicle movement. After off-road driving or crossing obsta- cles, inspect vehicle for any damage, especially vehicle undercarriage and suspension components. Failure to do so can adversely affect the vehicle's fu- ture performance, including increased chance of an accident.

앫 Check the vehicle clearance before

crossing obstacles.

앫 Select gear range 1 on the automatic

transmission (컄 page 121).

앫 Cross obstacles (e.g. tree stumps or

big rocks) very slowly by aiming one of the front wheels at the center of the ob- stacle, and repeat same with the rear wheel.

Ruts A number of off-road tracks or other by- ways have deep ruts which can cause the undercarriage to come in contact with the ground. 앫 Select gear range 1 on the automatic

transmission (컄 page 121).

앫 Drive next to the ruts rather than

through them if at all possible.

Special attention is needed when you cross obstacles on a steep incline. The vehicle could slide sideways as a result of its possible slanted position which in turn may result in the vehicle tipping or rolling over.

Operation Driving instructions

Returning from off-road driving

Warning!

If you feel a sudden significant vibration or ride disturbance, or you suspect that possi- ble damage to your vehicle has occurred, you should turn on the hazard warning flash- ers, carefully slow down, and drive with cau- tion to an area which is a safe distance from the roadway.

Inspect the tires and under the vehicle for possible damage. If the vehicle or tires ap- pear unsafe, have it towed to the nearest Mercedes-Benz Light Truck Center or tire dealer for repairs.

205

Operation Driving instructions

Off-road driving increases strain on the vehicle. We recommend that you inspect the vehi- cle for possible damage after each off-road trip. Recognizing any damage and a subse- quent timely repair reduces the chance of a possible breakdown or accident later on. Proceed as follows: 앫 Switch off the LOW RANGE mode

(컄 page 125).

앫 Remove excessive dirt from tires,

wheels, wheel housings, and under- body. For instance, after driving in mud, clean the radiator, chassis, engine, brakes, and wheels from extreme dirt using a strong jet of water.

앫 Inspect frame, oil pan, brake hoses, etc., as well as vehicle underbody for possible damage.

앫 Check tires for possible damage, clean all exterior lamps, and conduct a brake test.

앫 Check for brush or branches caught in

the undercarriage. They could increase the possibility of a fire, as well as cut fuel and/or brake lines, puncture rubber bellows of the axles or drive shafts.

앫 After continued operation in mud,

sand, water or other dirty conditions clean the brake discs, wheels, brake pads and check and clean axle joints.

Trailer towing

Warning!

Failure to use proper equipment and driving technique can result in a loss of vehicle con- trol when towing a trailer.

Improper towing or failure to follow the in- structions contained in this guide can result in serious injury. Follow the guidelines be- low carefully to assure safe trailer operation.

Ask your authorized Mercedes-Benz Light Truck Center should you require an explana- tion of information contained in this guide.

206

Trailer hitches 앫 Only install a trailer hitch receiver ap-

proved for your vehicle. For information on availability and in- stallation, see your authorized Mercedes-Benz Light Truck Center.

앫 The bumpers on your vehicle are not

designed for use with clamp-type hitch- es. Do not attach rental hitches or other bumper-type hitches to them.

앫 To reduce the possibility of damage, re-

move the hitch ball adaptor from the receiver when not in use.

Electrical connections The vehicle is prewired to accept the sev- en-wire harness included in the Mercedes-Benz approved trailer hitch re- ceiver kit. An additional four-pole conversion plug is included in the Mercedes-Benz supplied trailer hitch receiver kit. For further information, see your autho- rized Mercedes-Benz Light Truck Center.

Operation Driving instructions

Vehicle and trailer weights and ratings Gross Vehicle Weight Rating (GVWR) is the maximum permissible vehicle weight: 6614 lbs (3000 kg). Gross Vehicle Weight (GVW): Comprises weight of vehicle including fuel, tools, spare wheel, installed accessories, passengers, cargo and trailer tongue. It must never exceed the GVWR. Gross Axle Weight Rating (GAWR) is the maximum permissible axle weight:

front rear

2976 lbs 3858 lbs

(1350 kg) (1750 kg)

Gross Trailer Weight (GTW) is the maxi- mum permissible trailer weight to be towed: 5000 lbs (2260 kg). Trailer Tongue Weight Rating (TWR) is the maximum permissible weight on the trailer tongue: 500 lbs (225 kg) limit for Mercedes-Benz approved hitch receiver.

207

Operation Driving instructions

Loading a trailer 앫 When loading a trailer, you should ob- serve that neither the permissible GTW, nor the GVWR are exceeded. Maximum permissible values are listed on the safety compliance certification labels for the vehicle and for the trailer to be towed. The lowest value listed must be select- ed when determining how the vehicle and trailer are loaded.

앫 The tongue weight at the hitch ball

must be added to the GVW to prevent exceeding your Mercedes-Benz tow vehicle’s rear GAWR.

We recommend loading the trailer in such a manner that it has a tongue weight (TW) between 10% and 15% of the GTW.

208

Checking weights of vehicle and trailer 앫 To assure that the tow vehicle and trail- er are in compliance with the maximum permissible weight limits have the load- ed rig (tow vehicle including driver, pas- sengers and cargo, trailer fully loaded) weighed on a commercial scale.

앫 Check the vehicle’s front and rear

Gross Axle Weight (GAW), the GTW and TW. The values as measured must not be exceeded, according to the weight list- ed under “Vehicle and trailer weight and ratings”.

Attaching a trailer Observe maximum permitted trailer dimensions (width and length). Most states and all Canadian provinces require 앫 safety chains between your tow vehicle

and the trailer. The chains should be crisscrossed un- der the trailer tongue. They must be at- tached to the hitch receiver, and not to the vehicle’s bumper or axle. Be sure to leave enough slack in the chains to permit turning corners.

앫 a separate brake system at various

trailer weights.

앫 a break-away switch on trailers with a

separate brake system. The switch activates the trailer brakes in the possible event that the trailer might separate from the tow vehicle.

! Do not connect a trailer brake system (if trailer is so equipped) directly to the vehicle’s hydraulic brake system, as your vehicle is equipped with antilock brakes. If you do, neither the vehicle’s brakes nor the trailer’s brakes will func- tion properly.

The provided vehicle electrical wiring harness for trailer towing has a brake signal wire (color orange) for hook-up to a brake controller. You should consider using a trailer sway control system. For further infor- mation see your authorized Mercedes-Benz Light Truck Center.

Towing a trailer There are many different laws, including speed limit restrictions, having to do with trailer towing. Make sure your rig will be le- gal, not only for where you reside, but also for where you will be driving. A good source for this information can be the po- lice or local authorities. Note the following points, when driving with the trailer: 앫 In order to gain skill and an under-

standing of the vehicle’s behavior, you should practice turning, stopping and backing up in an area which is free from traffic.

앫 Before you start driving check the

앫 trailer hitch 앫 break-away switch 앫 safety chains 앫 electrical connections 앫 lighting and tires

Operation Driving instructions

Adjust the mirrors to permit unobstructed view beyond rear of trailer. 앫 If the trailer has electric brakes, start your vehicle and trailer moving slowly, and then apply only the trailer brake controller by hand to be sure the brakes are working properly.

앫 Always secure items in the trailer to

prevent load shifts while driving.

앫 When towing a trailer, check occasion- ally to be sure that the load is secure, and that lighting and trailer brakes (if so equipped) are functioning properly. 앫 Take into consideration that when tow- ing a trailer, the handling characteris- tics are different and less stable from those when operating the vehicle with- out a trailer. It is important to avoid sudden maneu- vers.

209

Operation Driving instructions

앫 The vehicle and trailer combination is heavier, and therefore is limited in ac- celeration and climbing ability, and re- quires longer stopping distances. It is more prone to reacting to side wind gusts, and requires more sensitive steering input.

앫 If possible, do not brake abruptly, but rather engage the brake slightly at first to permit the trailer to activate its brake. Then increase the braking force.

If the trailer should begin to sway, re- duce the vehicle’s speed and use the brake controller by hand to straighten out the vehicle and trailer. In no case should you attempt to straighten out the tow vehicle and trail- er by increasing the speed or overstee- ring and stepping on the brakes.

210

앫 If the transmission hunts between

앫 If the engine coolant rises to an ex-

gears on inclines, manually shift to a lower gear (select 4, 3, 2 or 1). A lower gear and reduction of speed re- duces the chance of engine overload- ing and/or overheating.

앫 On very steep inclines, not manageable with gear selector lever in position 1, switch transfer case to LOW RANGE mode (컄 page 125).

앫 When going down a long hill, shift into a lower gear and use the engine’s brak- ing effect. Avoid riding the brakes, thus overheat- ing the vehicle and trailer brakes.

tremely high temperature (coolant tem- perature needle approaching the red zone) when the air conditioning is on, turn off the air conditioning system. Engine coolant heat can be additionally vented by opening the windows, switching the climate control fan speed to high and setting the temperature control to the maximum hot position.

앫 Extreme care must be exercised since your vehicle with a trailer will require additional passing distance ahead than when driving without a trailer. Because your vehicle and trailer is longer than your vehicle alone, you will also need to go much farther ahead of the passed vehicle before you can re- turn to your lane.

Passenger compartment

Driving abroad

Abroad, there is an extensive Mercedes-Benz service network at your disposal. If you plan to drive into areas which are not listed in the index of your Mercedes-Benz Light Truck Center directo- ry, you should request pertinent informa- tion from your authorized Mercedes-Benz Light Truck Center.

Warning!

Always fasten items being carried as secure- ly as possible.

In an accident, during hard braking or sud- den maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless the items are securely fastened in the vehicle.

The rear cargo compartment is the preferred place to carry objects. Always use the parti- tion net when transporting cargo. Partition net cannot secure hard or heavy objects. Al- ways fasten items being carried as securely as possible using the cargo tie-down rings in the cargo floor area and fastening materials.

Telephones and two-way radios

Catalytic converter

Warning!

Never operate radio transmitters equipped with a built-in or attached antenna (i.e. with- out being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunc- tion of the vehicle’s electronic system, pos- sibly resulting in an accident and/or personal injury.

Radio transmitters, such as a portable tele- phone or a citizens band unit should only be used inside the vehicle if they are con- nected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation in- structions regarding use of an external an- tenna.

Your Mercedes-Benz is equipped with monolithic-type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial con- trol of the pollutants in the exhaust emis- sions. Keep your vehicle in proper operating condition by following our rec- ommended maintenance instructions as outlined in your Service Booklet.

To prevent damage to the catalytic con- verters, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and start a fire.

Warning!

As with any vehicle, do not idle, park or op- erate this vehicle in areas where combusti- ble materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

Emission control

Certain engine systems serve to keep the toxic components of the exhaust gases within permissible legal limits. These systems, of course, will function properly only when maintained strictly ac- cording to factory specifications. Any ad- justments on the engine should, therefore, be carried out only by qualified Mercedes-Benz Light Truck Center autho- rized technicians. Engine adjustments should not be altered in any way.

carried out regularly according to Mercedes-Benz servicing requirements. For details refer to the Service Booklet.

Warning!

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause uncon- sciousness and lead to death.

Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one win- dow fully open at all times.
