This indicates the number of plies or the number of layers of rubber-coated fabric in the tire tread and sidewall. Tire manufac- turers also must indicate the ply materials in the tire and sidewall, which include steel, nylon, polyester, and others.

Tire speed rating Part of tire designation; indicates the speed range for which a tire is approved.

Traction Force exerted by the vehicle on the road via the tires. The amount of grip provided.

Tread The portion of a tire that comes into contact with the road.

Operation Tires and wheels

Treadwear indicators Narrow bands, sometimes called “wear bars” that show across the tread of a tire when only 1/16 in (1.6 mm) of tread remains.

Vehicle maximum load on the tire Load on an individual tire that is determined by distributing to each axle its share of the maximum loaded vehicle weight and dividing it by two.

TWR (Tongue Weight Rating) Maximum permissible weight on trailer tongue.

Rotating tires

Warning!

Uniform Tire Quality Grading Standards A tire information system that provides consumers with ratings for a tire’s traction, temperature and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire.

Rotate front and rear wheels only if they are of the same dimension.

If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible.

Tire rotation can be performed on vehicles with tires of the same dimension all around. If your vehicle is equipped with tires of the same dimension all around, tires can be rotated, observing a front-to-rear rotation pattern that will maintain the intended rotation (spinning) direction of the tire (컄 page 368).

397

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 110 lb-ft (150 Nm).

Only use genuine Mercedes-Benz wheel bolts specified for your vehicle’s rims.

For information on wheel change, see the “Practical hints” section (컄 page 469) and (컄 page 497).

Operation Tires and wheels

In some cases, such as when your vehicle is equipped with mixed-size tires (different tire dimension front vs. rear), tire rotation is not possible. If applicable to your vehicle’s tire configu- ration, tires can be rotated according to the tire manufacturer’s recommended in- tervals in the tire manufacturer’s warranty pamphlet located in your vehicle literature portfolio. If none is available, tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if neces- sary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained (컄 page 368). Rotate tires before the characteristic tire wear pattern becomes visible (shoulder wear on front tires and tread center wear on rear tires). Thoroughly clean the mounting face of wheels and brake disks, i.e. the inner side of the wheels/tires, during each rotation. Check for and ensure proper tire inflation pressure.

398

왔 Winter driving Before the onset of winter, have your vehicle winterized at an authorized Mercedes-Benz Light Truck Center. This service includes: 앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the water of the windshield and headlamp cleaning system. Add MB Concentrate “MB SummerFit” to a premixed wind- shield washer solvent/antifreeze which is formulated for temperatures below freezing point (컄 page 551). 앫 Battery test. Battery capacity drops

with decreasing ambient temperature. A well charged battery helps to make sure that the engine can be started even at low ambient temperatures. 앫 Tire change. Mercedes-Benz recom-

mends 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.

Winter tires

Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Not all M+S rated tires provide special winter performance. Make sure the tires you use show the mountain/snowflake.marking on the tire sidewall. These tires meet specific snow traction performance requirements of the Rubber Manufacturers Association (RMA) and The Rubber Association of Can- ada (RAC) and have been designed specif- ically for use in snow conditions. Use of winter tires is the only way to achieve the maximum effectiveness of the ABS, ESP®, 4-ETS, and EBP in winter operation. For safe handling, make sure all mounted winter tires are of the same make and have the same tread design.

Operation Winter driving

Warning!

Winter tires with a tread depth under 1/6 in (4 mm) must be replaced. They are no long- er suitable for winter operation.

Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your vehicle, you must place a notice to this effect where it will be seen by the driver. Such notices are available from your tire dealer or from any authorized Mercedes-Benz Light Truck Center.

399

Operation Winter driving

Warning!

Snow chains

If you use your spare tire when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly.

Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Light Truck Center.

Block heater (Canada only)

The engine is equipped with a block heater. The electrical cable may be installed at an authorized Mercedes-Benz Light Truck Center.

! Even on vehicles with all-wheel-drive use snow chains on rear tires only. Some tire sizes do not leave adequate clearance for snow chains. To help avoid serious damage to your vehicle or tires, use of snow chains is not permissible with the spare wheel.

! Vehicles with air suspension package*: When driving with snow chains, do not select SPORT mode (컄 page 269).

i When driving with snow chains, you may wish to deactivate the ESP® (컄 page 99) before setting the vehicle in motion. This will improve the vehicle’s traction.

Snow chains should only be driven on snow-covered roads at speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow.

Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations (컄 page 536).

앫 Snow chains should only be used on the rear wheels. Follow the manufac- turer’s mounting instructions. 앫 Only use snow chains that are

approved by Mercedes-Benz. Your authorized Mercedes-Benz Light Truck Center will be glad to advise you on this subject.

앫 Use of snow chains may be prohibited depending on location. Always check local and state laws before installing snow chains.

앫 Do not use snow chains on the spare

wheel (컄 page 538).

왔 Maintenance We strongly recommend that you have your vehicle serviced by an authorized Mercedes-Benz Light Truck Center, in accordance with the Maintenance Booklet at the times called for by the maintenance service indicator display. Failure to have the vehicle maintained in accordance with the Maintenance Booklet and maintenance service indicator at the designated times/mileage will result in vehicle damage not covered by the Mercedes-Benz Limited Warranty.

Maintenance service indicator message

The maintenance service indicator mes- sage will notify you when your next mainte- nance service is due.

Starting approximately 1 month before your next maintenance service is due, one of the following messages will appear in the multifunction display while you are driving or when you switch on the ignition (example service A):

Service A in XXXXX miles (km) Service A in XXX days Service A in X day Service A due now The maintenance services will be indicated by showing a service type A through type H in the multifunction display. Types A through H are classified based on estimat- ed time needed to perform the mainte- nance service, ranging: from

Service A (approx. 1 hour)

to

Service H (approx. 8 hours)

Operation Maintenance

Refer to Maintenance Booklet for a listing of maintenance services and intervals they need to be performed at.

i Vehicles equipped with Vehicle Maintenance System only (U.S. vehicles): The Vehicle Maintenance System in your vehicle tracks distance driven and the time elapsed since your last maintenance service and calcu- lates other maintenance service work required.

401

Operation Maintenance

i Vehicles equipped with FSS PLUS (Flexible Service System PLUS) only (Canada vehicles): 앫 FSS PLUS evaluates engine temperature, oil level, vehicle speed, engine speed, distance driven and the time elapsed since your last service and calculates other maintenance service work required.

앫 The interval between maintenance services depends on your driving habits. A gentle driv- ing style, moderate engine speeds and the avoidance of short-distance trips will length- en the interval between services.

Clearing the maintenance service indicator message The maintenance service indicator mes- sage is automatically cleared 앫 after approximately 10 seconds when

you switch on the ignition or when reaching the maintenance service threshold while driving

앫 after approximately 30 seconds, once

the suggested maintenance service term has passed

402

You can also clear it yourself:

1 Reset button 왘 Press reset button 1 on the instru-

ment cluster. The maintenance service indicator message is cleared and the standard display appears in the multifunction display (컄 page 154).

Resetting the maintenance service indicator

i If the maintenance service indicator was inadvertently reset, have an authorized Mercedes-Benz Light Truck Center correct it. Only reset if the proper maintenance service has been performed. Resetting the system without performing the proper service as called for by the maintenance service indicator will result in engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

In the event that the maintenance service on your vehicle is not carried out by an authorized Mercedes-Benz Light Truck Center, you can have the maintenance service indicator reset. The automotive maintenance facility carrying out the maintenance service will find the informa- tion for resetting the maintenance service indicator in the maintenance-relevant information for your vehicle. Such informa- tion is available from either your authorized Mercedes-Benz Light Truck Center or directly from Mercedes-Benz.

403

Operation Vehicle care

Cleaning and care of the vehicle

Regular and proper care will help to maintain the value of your vehicle. The best way to protect your vehicle from harmful environmental influences is to wash it and use protective treatments regularly.

Warning!

Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside.

Never use fluids or solvents that are not de- signed for cleaning your vehicle.

Always lock away cleaning products and keep them out of reach of children.

404

Frequent washing reduces and/or eliminates the aggressiveness and potency of the above adverse influences. More frequent washings are necessary to deal with unfavorable conditions: 앫 near the ocean 앫 in industrial areas (smoke, exhaust

emissions)

앫 during winter operation You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated.

While in operation, even while parked, your vehicle is subjected to varying external in- fluences which, if gone unchecked, can at- tack the paintwork as well as the underbody and cause lasting damage. Such damage is caused not only by extreme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 Gravel and stone chipping To avoid paint damage, you should immediately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins, etc.

Operation Vehicle care

Your vehicle has been treated at the facto- ry with a wax-base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others ap- plied later. We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at an authorized Mercedes-Benz Light Truck Center. Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at an authorized Mercedes-Benz Light Truck Center.

The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care products.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

Paintwork, painted body components

! Affixing stickers, magnets, adhesive tape or similar materials to painted body components may damage the paintwork.

Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should normally be done every 3 to 5 months, depending on the climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of dirt embedding (i.e. loss of gloss).

Power washer

! Follow the instructions provided by the power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. Never use a round nozzle to power-wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connectors, seals, or other rubber parts.

i Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.

405

Operation Vehicle care

Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. 왘 Use the appropriate MB-Touch-Up

Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.).

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical compo- nents and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax, should be applied to the engine compartment after every en- gine cleaning. Before applying, all control linkage bushings and joints should be lu- bricated. The poly-V-belt and all pulleys should be protected from any wax.

Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels.

i Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approximately 3 ft (approxi- mately 1 m), the vehicle could be inadvertently locked or unlocked.

Hand-wash Do not use hot water or wash your vehicle in direct sunlight. 왘 Only use a mild car wash detergent,

such as Mercedes-Benz approved Car Shampoo.

왘 Thoroughly spray the vehicle with a dif-

fused jet of water. Direct only a very weak spray towards the ventilation intake.

왘 Use plenty of water and rinse the

sponge and chamois frequently.

왘 Rinse with clean water and thoroughly

dry with a chamois. Do not allow cleaning agents to dry on the finish.

! Do not use scouring agents on these parts. Never apply strong force and only use a soft, non-sratching cloth when cleaning the vehicle. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the paint.

406

Operation Vehicle care

Automatic car wash You can have your car washed in an auto- matic car wash from the start. Automatic car washes without brushes are prefera- ble. 왘 To protect the filter system, switch the climate control (컄 page 208) or the au- tomatic climate control (컄 page 222) to air recirculation mode.

! Do not clean your vehicle in an automatic touchless car wash which use caustic spray. Otherwise the caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it before running it through the automatic car wash.

! If you want the gear position to remain in N (for example when the vehicle is pulled through a car wash) 앫 do not remove the SmartKey from the starter

switch

or, when using KEYLESS-GO* 앫 do not turn off the engine using the

KEYLESS-GO start/stop button* and open the driver’s door.

Otherwise, the transmission will shift to P and lock the wheels, preventing the vehicle from be- ing pulled through a car wash.

! Make sure that the windshield wiper switch is set to 0 (컄 page 61). Otherwise, e.g. the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors.

i After running the vehicle through an auto- matic car wash, wipe any wax off of the wind- shield (컄 page 410). This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield. When leaving the car wash, make sure that the mirrors are folded out. Otherwise they may vibrate.

Ornamental moldings For regular cleaning and care of ornamen- tal moldings, use a damp cloth.

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome clean- er. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Light Truck Center.

407

Operation Vehicle care

Headlamps, brake lamps, tail lamps, side markers, turn signal lenses 왘 Use a mild car wash detergent, such as

Mercedes-Benz approved Car Sham- poo, with plenty of water.

! Only use window cleaning solutions that are suitable for plastic lamp lenses. Window clean- ing solutions which are not suitable may damage the plastic lamp lenses of the headlamps. There- fore, do not use abrasives, solvents or cleaners that contain solvents. Never apply strong force and only use a soft, non-scratching cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Otherwise you may scratch or damage the lens surface.

Operation Vehicle care

Cleaning the windows and the wiper blades

Warning!

For safety reasons, switch off wipers and re- move SmartKey from starter switch (vehicles with KEYLESS-GO*: Make sure the vehicle’s on-board electronics have status 0) before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury.

왘 Fold the wiper arms forward until they

engage.

! Do not pull on the wiper blade inserts. They could tear. 왘 Clean the wiper blade inserts with a

clean cloth and detergent solution.

410

왘 Use a soft, clean cloth and a mild win-

dow cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recom- mended.

! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch or pressing the KEYLESS-GO start/stop button (vehicles with KEYLESS-GO*). Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield.

! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners con- taining solvents. Do not touch the inside of the front, rear or side windows and the power tilt/sliding sunroof* or rear panorama roof with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Light alloy wheels If possible, clean wheels once a week. 왘 Use Mercedes-Benz approved Wheel Care, a soft bristle brush and a strong spray of water for cleaning the light al- loy wheels.

! Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat.

! The vehicle should not be parked for an ex- tended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corrosion of the brake disks and brake pads. Non-approved wheel cleaners may also damage the wheel paint if the car is not driven after cleaning. Therefore, the vehicle’s brake system should always be warmed-up before it is parked after cleaning. To do so, please drive your vehicle for several minutes to allow the brakes to dry. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.

Plastic and rubber parts 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.

왘 Wipe with a cloth moistened in a

lukewarm solution. The surface may temporarily change color. If this is the case, wait for it to dry.

Warning!

Do not use cleaners containing solvents or cockpit care sprays to clean the cockpit or the steering wheel. Cleaners containing sol- vents will make the surface porous and vehi- cle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment.

! Do not use oil, wax or scouring agents on these parts. Never apply strong force and only use a soft, non-scratching cloth when cleaning the surface. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the surface.

Hard plastic trim items 왘 Use Mercedes-Benz approved Interior Care, a soft, lint-free cloth and apply with light pressure.

! Never apply strong force and only use a soft, non-scratching cloth when cleaning the surface. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the surface.

Problem l The red distance warning lamp comes on while driving and you hear a warning chime sound.

1 The red SRS indicator lamp comes

on while driving.

Possible cause/consequence 앫 You are gaining too rapidly on the vehicle

ahead of you.

앫 The distance warning system has recog-

nized a stationary obstacle on your probable line of travel.

There is a malfunction in the restraint systems. The air bags or emergency tensioning device (ETDs) could deploy unexpectedly or fail to deploy unexpectedly in an accident.

Suggested solution 왘 Apply the brakes immediately. 왘 Carefully observe the traffic

situation. You may need to brake or maneuver to avoid hitting an obstacle.

왘 Drive with added caution to the

nearest authorized Mercedes-Benz Light Truck Center.

Warning!

In the event a malfunction of the SRS is indi- cated as outlined above, the SRS may not be operational. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Light Truck Center immedi- ately to have the system checked, otherwise

the SRS may not be activated when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpect- edly and unnecessarily which could result in an accident and/or injury to you or to others.

Problem H USA only:

Combination low tire pres- sure/TPMS malfunction telltale for the TPMS illuminates contin- uously. Canada only: Low tire pressure telltale for the Advanced TPMS* illuminates continuously.

Possible cause/consequence The TPMS (USA only) or Advanced TPMS* (Canada only) detects a loss of pressure in at least one tire.

H USA only:

There is a malfunction in the TPMS.

Combination low tire pres- sure/TPMS malfunction telltale for the TPMS flashes 60 seconds and then stays illuminated.

Suggested solution 왘 Carefully bring the vehicle to a halt, avoiding abrupt steering and braking maneuvers. Observe the traffic situation around you.

왘 Read and observe messages in the

multifunction display.

If the tire inflation pressure in the respec- tive tire(s) has (have) been corrected, the combination low tire pressure/TPMS mal- function telltale goes out after few minutes driving. 왘 Read and observe messages in the

multifunction display.

왘 Have the TPMS checked by an

authorized Mercedes-Benz Light Truck Center.

After the malfunction has been remedied the combination low tire pressure/TPMS malfunction telltale goes out after few minutes driving.

424

Warning!

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the vehicle placard or the tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or the tire inflation pressure label, you should determine the proper tire infla- tion pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitor- ing system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accord- ingly, when the low tire pressure telltale illu- minates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significant- ly underinflated tire causes the tire to over- heat and can lead to tire failure.

Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv- er’s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

USA only: Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is com- bined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then remain continuously illuminated. This sequence will continue upon subse- quent vehicle start-ups as long as the mal- function exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

Practical hints What to do if …

TPMS malfunctions may occur for a variety of reasons, including the installation of in- compatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

425

Possible cause/consequence The system is malfunctioning.

Suggested solution 왘 Have the system checked as soon as

possible by an authorized Mercedes-Benz Light Truck Center. 왘 Also read and observe messages in the multifunction display and follow corrective steps (컄 page 440).

Vehicle status messages in the multifunction display

Warning and malfunction messages appear in the multifunction display located in the instrument cluster. Certain warning and malfunction messag- es are accompanied by an audible signal. Address these messages accordingly and follow the additional instructions given in this Operator’s Manual. Selecting the vehicle status message memory menu in the control system (컄 page 163) displays both cleared and uncleared messages. High-priority messages appear in the multifunction display in red color.

Certain messages of high priority cannot be cleared from the multifunction display using the reset button (컄 page 145) or button j, k, ÿ, or è on the multifunction steering wheel. Other messages of high priority and mes- sages of less immediate priority can be cleared from the multifunction display using the reset button (컄 page 145) or button j, k, ÿ, or è on the multifunction steering wheel. They are then stored in the vehicle status message memory (컄 page 163). Remember that clearing a message will only make the mes- sage disappear. Clearing a message will not correct the condition that caused the message to appear.

Warning!

All categories of messages contain important information which should be taken note of and, where a malfunction is indicated, addressed as soon as possible at an authorized Mercedes-Benz Light Truck Center.

Failure to repair condition noted may cause damage not covered by the Mercedes-Benz Limited Warranty, or result in property dam- age or personal injury.
