! The lighter socket can accommodate 12V DC electrical accessories (up to a maximum of 180 W) designed for use with the standard “cigarette lighter” plug type. Keep in mind, how- ever, that connecting accessories to the lighter socket (for example extensive connecting and disconnecting, or using plugs that do not fit prop- erly) can damage the lighter socket. With the socket damaged, the lighter may no longer be able to be placed in the heating (pushed-in) posi- tion, or the lighter may pop out too early with the lighter not hot enough. To help avoid damaging the cigarette lighter socket, we recommend connecting 12V DC elec- trical accessories designed for use with the stan- dard “cigarette lighter” plug type to the 12V power outlets (컄 page 287) in your vehicle whenever possible.

i If the engine is off, and the cigarette lighter is being used extensively, the vehicle battery may become discharged.

Power outlets

! If you use all power outlets in the vehicle, make sure that the maximum current drawn does not exceed 55 A.

i The power outlets can be used to accommodate 12V DC electrical accessories (e.g. air pump, auxiliary lamps) up to a maximum of 240 W. If the engine is off, the battery may become dis- charged if used for long periods of time.

i You can use the power outlets, except for the power outlet in the front center console, even if the ignition is switched off. An emergency shut-off feature ensures that the vehicle’s electrical voltage does not fall below a minimum level. If the voltage drops to this mini- mum level, the power outlets are automatically switched off. This ensures that enough power re- mains to start the engine.

Telephone*

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 serious 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. The external antenna must be approved by Mercedes-Benz. Please contact an autho- rized Mercedes-Benz Light Truck Center for information on the installation of an ap- proved external antenna. Refer to the radio transmitter operation instructions regard- ing use of an external antenna.

Warning!

Please do not forget that your primary re- sponsibility is to drive the vehicle. A driver’s attention to the road must always be his/her primary focus when driving. For your safety and the safety of others, we rec- ommend that you pull over to a safe location and stop before placing or taking a tele- phone call. If you choose to use the telephone1 while driving, please use the hands-free device and only use the telephone when road, weather and traffic conditions permit. Some jurisdictions prohibit the driver from using a cellular telephone while driving a vehicle. Only operate the COMAND system1 if road, weather and traffic conditions permit.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximate- ly 14 m) every second.

Garage door opener

The integrated remote control is capable of operating up to three separately controlled devices. It provides a convenient way to re- place up to three hand-held remote con- trols used to operate devices such as garage door openers, gate openers, or oth- er devices compatible with HomeLink® or some other systems. Before the integrated remote control can be used, it must be programmed to the ga- rage door opener, gate operator or other device you wish to operate. See the follow- ing instructions for programming informa- tion.

302

Warning!

Before programming the integrated remote control to a garage door opener or gate operator, make sure people and objects are out of the way of the device to prevent po- tential harm or damage. When programming a garage door opener, the door moves up or down. When programming a gate operator, the gate opens or closes.

Do not use the integrated remote control with any garage door opener that lacks safety stop and reverse features as required by U.S. federal safety standards (this includes any garage door opener model manufactured 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.

Step 5: 왘 After indicator lamp 1 changes from a slow to a rapidly flashing light, release the hand-held remote control button and the signal transmitter button.

Step 6: 왘 Press and hold the just-trained signal transmitter button (2, 3 or 4) and observe indicator lamp 1. If indicator lamp 1 stays on constantly, programming is complete and your device should activate when the respective signal transmitter button (2, 3 or 4) is pressed and re- leased.

i If indicator lamp 1 flashes rapidly for about 2 seconds and then turns to a constant light, continue with programming steps 8 through 12 as your garage door opener may be equipped with the “rolling code” feature.

304

Step 7: 왘 To program the remaining two signal transmitter buttons, repeat the steps above starting with step 3.

Rolling code programming To train a garage door opener (or other rolling code devices) with the rolling code feature, 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 “training” button may also be referred to as “learn” or “smart” button. If there is difficulty locating the transmitting button, refer to the garage door opener Operator’s Manual.

Step 9: 왘 Press the “training” button on the ga-

rage door opener motor head unit. The “training light” is activated.

You have 30 seconds to initiate the follow- ing two steps. Step 10: 왘 Return to the vehicle and firmly press, hold for 2 seconds and release the pro- grammed signal transmitter button (2, 3 or 4).

Step 11: 왘 Press, hold for 2 seconds and release same signal transmitter button a sec- ond time to complete the training pro- cess.

i Some garage door openers (or other rolling code equipped devices) may require you to press, hold for 2 seconds and release the same signal transmitter button a third time to complete the training process.

Step 4: 왘 Press and hold the signal transmitter button (2, 3 or 4). Do not release this button until it has been successful- ly trained.

왘 While still holding down the signal transmitter button (2, 3 or 4), “cycle” your hand-held remote control button 6 as follows: Press and hold button 6 for 2 seconds, then release it for 2 seconds, and again press and hold it for 2 seconds. Repeat this se- quence on the hand-held remote con- trol until the frequency signal has been learned. Upon successful training, indicator lamp 1 will flash slowly and then rapidly after several seconds.

왘 Proceed with programming step 5 and

step 6 to complete.

Step 12: 왘 Confirm the garage door operation by pressing the programmed signal trans- mitter button (2, 3 or 4).

Step 13: 왘 To program the remaining two signal transmitter 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 integrated signal transmitter to pick up the signal 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 difficulties programming a gate operator (regardless of where you live) by using the programming procedures, replace step 4 with the following:

i Upon completion of programming the inte- grated remote control, make sure you retain the hand-held remote control that came with the ga- rage door opener, gate operator or other device. You may need it for use in other vehicles, for fu- ture programming of an integrated remote con- trol, or simply for continued use as a hand-held remote control to operate the respective device in other situations.

Reprogramming a single signal trans- mitter button To program a device using a signal trans- mitter button previously trained, follow these steps: 왘 Switch on the ignition (컄 page 40). 왘 Press and hold the desired signal transmitter button (2, 3 or 4). Do not release the button.

왘 Indicator lamp 1 will begin to flash af- ter 20 seconds. Without releasing the signal transmitter button, proceed with programming starting with step 3.

Operation of integrated remote control 왘 Switch on the ignition (컄 page 40). 왘 Select and press the appropriate inte- grated signal transmitter button (2, 3 or 4) to activate the remote con- trolled device. The integrated remote control trans- mitter continues to send the signal as long as the button is pressed – up to 20 seconds.

Erasing the integrated remote control memory 왘 Switch on the ignition (컄 page 40). 왘 Simultaneously press and hold outer signal transmitter buttons 2 and 4, for approximately 20 seconds, until indicator lamp 1 flashes rapidly. Do not hold for longer than 30 seconds. The codes of all three channels are erased.

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

Programming tips If you are having difficulty programming the integrated remote control, here are some helpful tips: 앫 Check the frequency of hand-held

remote control 5 (typically located on the reverse side of the remote). The in- tegrated remote control is compatible with radio-frequency devices operating between 280-390 MHz.

앫 Put a new battery in hand-held remote control 5. This will increase the likeli- hood of the hand-held remote control sending a faster and more accurate sig- nal to the integrated remote control.

앫 While performing step 3, hold

hand-held remote control 5 at differ- ent lengths and angles from the signal transmitter button (2, 3 or 4) you are programming. Attempt varying angles at the distance of 2 to 5 in (5 to 12 cm) away or the same angle at varying distances.

앫 If another hand-held remote control is available for the same device, try the programming steps again using that other hand-held remote control. Make sure new batteries are in the hand-held remote control before beginning the procedure.

앫 Straighten the antenna wire from the

garage door opener assembly. This may help improve transmitting and/or receiving signals.

i Certain types of garage door openers are in- compatible with the integrated remote control. If you should experience further difficulties with programming the integrated remote control, contact an authorized Mercedes-Benz Light Truck Center, or call Mercedes-Benz Customer Assistance Center (in the USA only) at 1-800-FOR-MERCedes, or Customer Service (in Canada) at 1-800-387-0100.

Operation The first 1000 miles (1500 km)

In the “Operation” section you will find detailed information on operating, main- taining and caring for your vehicle.

310

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 engine speeds (no more than 2/3 of maximum rpm in each gear).

앫 Shift gears in a timely manner. 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 gear ranges 3, 2 or 1

(컄 page 192) only when driving at moderate speeds (for hill driving).

After 1000 miles (1500 km) you may gradually increase vehicle and engine speeds to the permissible maximum.

! Additional instructions for ML 63 AMG: 앫 During the first 1000 miles (1500 km), do not exceed a speed of 85 mph (140 km/h).

앫 During this period, avoid engine speeds

above 4500 rpm in each gear. 앫 Shift gears at the correct time. 앫 Select C as the preferred shift program

(컄 page 194) for the first 1000 miles (1500 km).

All of the above instructions, as may apply to your vehicle type, also apply when driv- ing the first 1000 miles (1500 km) after the engine, the transfer case, the front dif- ferential or the rear differential has been replaced.

i Always obey applicable speed limits.

왔 Driving instructions Drive sensibly – save fuel

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

tion pressures.

앫 Remove unnecessary loads. 앫 Remove carriers* when not in use. 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 Maintenance Booklet and as required by the Maintenance System. Contact an 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 areas.

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 judgment.

The possibility of a serious or even fatal accident 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.

Make sure that absolutely no objects are ob- structing the pedal’s range of movement. Keep the driver’s footwell clear of all obsta- cles. If there are any floormats or carpets in the footwell, make sure that the pedals still have sufficient clearance.

During sudden driving or braking maneu- vers, the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.

311

Operation Driving instructions

Power assistance

Warning!

With the engine 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.

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 re- duced and increased pedal pressure may be necessary to obtain expected braking ef- fect. Maintain a safe distance from vehicles in front.

312

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.

! Operational or performance test must only be conducted on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Light Truck Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty.

! Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO* start/stop button in position 0 or 1) when testing the parking brake on a brake test dynamometer and such testing should be no longer than 10 seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

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.

Operation Driving instructions

All checks and service work on the brake system should be carried out by qualified technicians only. Contact an authorized Mercedes-Benz Light Truck Center. Only install 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. When using the engine’s braking power, a drive wheel may not spin for an extended period of time, e.g. on slippery road surfaces. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

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

Warning!

Make sure not to endanger any other road users when carrying out these braking maneuvers.

Refer to the description of the Brake Assist System (BAS) (컄 page 100). Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir. The brake fluid level in the reservoir may be too low if the brake warning lamp in the instrument cluster comes on and an acoustic warning sounds although the parking brake is released (컄 page 401). Observe additional messages in the multi- function display that may appear (컄 page 430). Have the brake system inspected immediately. Contact an authorized Mercedes-Benz Light Truck Center.

313

Operation Driving instructions

High-performance brake system (ML 63 AMG only) The high-performance brake system is de- signed to operate under the extremely high operating demands required to accommo- date the performance capabilities of the vehicle. The brakes may produce a squeak- ing-type noise depending on the 앫 vehicle speed 앫 brake force applied 앫 ambient conditions, e.g. temperature

and humidity

As with any brake system, the wear of indi- vidual brake system components such as brake pads or disks strongly depends on your driving style and the conditions under which you operate the vehicle. Thus, a driv- ing style calling for high demand braking will cause your vehicle’s brakes to wear more quickly.

314

Warning!

New vehicle brake pads and discs, and replacement brake pads and discs may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period.

Excessive high demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition mes- sages in the multifunction display. Especial- ly for high performance driving, it is important to maintain and have the brake system checked regularly.

Parking brake When driving on wet roads or dirt covered surfaces, road salt and/or dirt can get into the parking brake. To prevent corrosion and a reduction in the braking power of the parking brake, observe the following: 왘 From time to time, lightly engage the

parking brake before driving off.

왘 Drive a distance of approximately

110 yds (100 m) at a maximum speed of 12 mph (20 km/h).

Warning!

While performing this procedure, please assure that the vehicle is stopped before applying the parking brake. Otherwise the rear wheels could lock up. You could lose control of the vehicle and cause an accident. In addition, the vehicle’s brake lights do not light up when the parking brake is engaged. Make sure not to endanger any other road users when you engage the parking brake.

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 driving off on a slippery surface, do not allow a drive wheel to spin for an extended 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.

! Simultaneously depressing the accelerator pedal and applying the brake reduces engine performance and causes premature brake and drivetrain wear.

Parking

Warning!

Do not park this vehicle in areas where com- bustible 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.

To reduce the risk of personal injury or dam- age to the vehicle drivetrain as a result of vehicle movement, before turning off the en- gine and leaving the vehicle always: 앫 Keep right foot on brake pedal. 앫 Firmly depress parking brake pedal. 앫 Set the automatic transmission to

position P.

앫 Slowly release brake pedal. 앫 When parked on an incline, turn front

wheel towards the road curb.

Operation Driving instructions

앫 Turn the SmartKey or the SmartKey with

KEYLESS-GO* to starter switch position 0 and remove, or press KEYLESS-GO* start/stop button (vehi- cles with KEYLESS-GO*).

앫 Take the SmartKey or the SmartKey with KEYLESS-GO* with you and lock vehicle when leaving.

Tires

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.

315

Operation Driving instructions

컄컄

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

Treadwear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approximately 1/16 in (1.6 mm), at which point the tire is considered worn and should be replaced. The treadwear indicator appears as a solid band across the tread.

Warning!

Although the applicable federal motor vehicle safety laws consider a tire to be worn when the treadwear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recommend that you do not allow your tires to wear down to that level.

316

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

Warning!

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.

For more information, see “Tires and wheels” (컄 page 348).

Hydroplaning

Depending on the depth of the water layer on the road, hydroplaning may occur, even at low speeds and with new tires. Reduce vehicle 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. 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 winter tires (컄 page 384) with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season to make sure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance compared to summer tires. Stopping distance, however, is still consid- erably greater than when the road is not covered with snow or ice. Exercise appro- priate caution.

! Avoid spinning of a 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 prudent driving speeds appropriate to pre- vailing 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 failure, causing loss of vehicle control and possibly resulting in an accident and/or serious injury and possible death, for you and for others.

An electronic speed limiter prevents your vehicle from exceeding a speed of: 앫 ML 320 CDI

ML 350
ML 550
ML 320 CDI (with Sport Package*) ML 350 CDI (with Sport Package*) ML 550 CDI (with Sport Package*): 130 mph (210 km/h)

앫 ML 63 AMG:

155 mph (250 km/h)

Operation Driving instructions

앫 ML 63 AMG with increased top

speed*: 171 mph (275 km/h)

The factory equipped tires on your vehicle may have a tire speed rating above the maximum speed permitted by the electronic speed limiter. Make sure your tires have the required tire speed rating as specified for your vehicle in the “Technical data” section (컄 page 515), for example when purchasing new tires. For information on how to identify the tire speed rating on a tire’s sidewall, see “Tire size designation, load and speed rating” (컄 page 370). If you are uncertain about the correct reading of the information given on a tire’s sidewall, any authorized Mercedes-Benz Light Truck Center will be glad to assist you.

i For information on speed ratings for winter tires, see “Winter tires” (컄 page 384). For additional general information on tire speed markings on the tire sidewall, see “Tire speed rating” (컄 page 382).

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, shift the automatic transmission to position N. Try to keep the vehicle under control by corrective steering action.

i For information on driving with snow chains, see “Snow chains” (컄 page 385).

318

Warning!

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.

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.

Make sure not to endanger any other road users when carrying out these braking maneuvers.

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.

Warning!

Standing water

For more information, see “Driving through water” (컄 page 324).

Operation Driving instructions

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 384).

! 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 wa- ter into the engine and auxiliary equipment, thus damaging them. If you must drive through standing water, drive slowly to prevent water from entering the pas- senger compartment or the engine compart- ment. Water in these areas could cause 앫 damage to electrical components 앫 wiring of the engine or transmission or could result 앫 in water being ingested by the engine

through the air intake, causing severe inter- nal engine damage.

Any such damage is not covered by the Mercedes-Benz Limited Warranty.

i Vehicles with air suspension program*: Select the raised level (컄 page 255) before driving through standing water.

Off-road driving

Warning!

Do not load items on the basic carrier bars*. It may cause instability during some maneu- vers which could result in an accident.

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. The vehicle might otherwise rollover. If in doing so the vehicle begins to show a tendency to roll, immediately steer into a line of gravity (straight up or downhill).

Operation Driving instructions

컄컄

Never let the vehicle roll backwards in idle. You may lose control of the vehicle if you use only the service brake. For information on driving downhill, see “Driving downhill” (컄 page 324).

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.

320

Warning!

Vehicles with air suspension program*:

Please be aware that by raising the vehicle level, the center of gravity also rises. There- fore, always ensure that the vehicle level is as low as possible. With higher ride height the ESP® may activate earlier in certain situations.

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.
