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 195) 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.

Operation Driving instructions

Fuel consumption is also increased by driving in cold weather, in stop-and-go traf- fic, on short trips and in hilly areas.

Pedals

Warning!

Drinking and driving

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.

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 (U.S. vehi- cles) or FSS PLUS (Canada vehicles). Contact an authorized Mercedes-Benz Light Truck Center.

Power assistance

Brakes

Warning!

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.

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.

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 dynanometer. 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 brakes 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.

326

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.

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 97).

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 415). Observe additional messages in the multi- function display that may appear (컄 page 449). Have the brake system inspected immediately. Contact an authorized Mercedes-Benz Light Truck Center. 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.

Operation Driving instructions

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.

327

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.

328

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 damage to the vehicle drivetrain, as a result of vehicle movement, before turning off the engine 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 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.

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.

329

Operation Driving instructions

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. 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.

330

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 365).

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 399) 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.

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 400).

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!

Warning!

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

i For information on speed ratings for winter tires, see “Winter tires” (컄 page 399). For additional general information on tire speed markings on the tire sidewall, see “Tire speed rating” (컄 page 397).

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.

332

Operation Driving instructions

Warning!

Standing water

For more information, see “Driving through water” (컄 page 338).

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!

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 399).

! 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 package*: Select the raised level (컄 page 270) 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 338).

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.

334

Warning!

Vehicles with air suspension package*:

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.

Special driving features for off-road driving The following driving features are available for specific kind of operation: 앫 Off-road – ABS (컄 page 97) 앫 Off-road – ESP® (컄 page 101) 앫 Off-road – 4-ETS (컄 page 102) 앫 Hill start assist system (컄 page 192) 앫 Downhill Speed Regulation (DSR)

Off-road driving rules 앫 Engage the off-road driving program

(컄 page 268) before driving under off-road conditions.

앫 Vehicles with air suspension package*:

Make sure you select a vehicle level (컄 page 270) appropriate to the topo- graphical conditions. Always make sure the vehicle has enough ground clearance.

앫 Fasten items being carried as securely

as possible (컄 page 281).

앫 Always navigate gradients with the en- gine on and with the transmission en- gaged in a gear. Switch on the DSR (컄 page 265) to help maintain a preset speed.

! Observe the following during off-road driving: 앫 Keep doors, tailgate, windows, and

tilt/sliding sunroof* closed whenever driving off-road.

앫 Adjust vehicle speed to condition of terrain. The more uneven, rutty and steeper the ter- rain, the lower the speed should be. Drive through water slowly at an even speed, avoiding a bow wave.

앫 Be especially careful when driving in un-

known territory. It may be necessary to get out of the vehicle and scout the path you in- tend to take.

앫 Watch out for obstacles, such as rocks,

holes, tree stumps and ruts.

앫 Before driving through water, determine its

depth.

앫 Do not stop vehicle while immersed in water,

and do not shut off the engine.

Operation Driving instructions

앫 In sandy soil, drive at a steady speed as al- lowed by conditions. This helps overcome the vehicle rolling resistance and reduces the likelihood of the vehicle sinking into the ground.

앫 Do not initiate jumps with the vehicle. It interrupts the forward momentum of the vehicle.

앫 Always drive onto slopes with the engine

running and the vehicle in gear.

앫 Do not shift automatic transmission to

position N.

Warning!

Do not reduce the tire inflation pressure before driving through sand. However, if you do so, remember to correct the tire inflation pressure (컄 page 375) before continuing your trip. Driving with reduced tire inflation pressure increases the risk of losing control of the vehicle and rolling over.

335

Operation Driving instructions

Checklist before off-road driving

Engine oil level 앫 Check the engine oil level with the

control system (ML 500 only) (컄 page 358), or with the oil dipstick (except ML 500) (컄 page 360). Only with a proper oil level can the vehicle obtain a trouble-free oil supply, even on steep gradients.

! If the engine oil level warning lamp (컄 page 453) comes on while driving, stop the vehicle in a safe location or as soon at is safe to do so. Check the engine oil level (컄 page 360). The engine oil level warnings should not be ignored. Extended driving with the symbol displayed could result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty.

336

Tires 앫 Check the tread depth and maintain

specified tire inflation pressure (a placard with the recommended tire inflation pressures is located on the driver’s door B-pillar (컄 page 369)).

앫 Check tires for possible damage and

remove foreign objects.

앫 Replace missing valve caps.

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

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 100% grade which is equivalent to a slope angle of 45 degrees. Keep in mind that the climbing ability of the vehicle depends on terrain conditions.

Warning!

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.

Operation Driving instructions

i The hill start assist system supports you when driving uphill. For more information, see “Hill start assist sys- tem” (컄 page 192).

Traction in steep terrain The maximum vehicle climbing ability is a 100% grade which is equivalent to a slope angle of 45 degrees. Keep in mind that the climbing ability of the vehicle depends on terrain conditions. Be easy on the accelerator and watch for continuous wheel traction when driving in steep terrain.

i 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 towards the rear 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.

337

Operation Driving instructions

Driving across a hilltop Decelerate just ahead of a hilltop (do not shift automatic transmission to position N), to prevent the vehicle from speeding up too much after climbing a hill. Use the momentum of the vehicle to drive across the hilltop. After climbing a hill, driving in this manner prevents the vehicle from: 앫 losing ground contact when cresting

hills

앫 losing its forward momentum 앫 speeding up too much after climbing

the hill

Driving downhill 앫 Drive slowly. 앫 Do not drive at an angle to the incline. Steer into the line of gravity and drive with the front wheels pointing straight downhill. Otherwise, the vehicle may slide sideways off the path and roll over.

338

앫 Shift automatic transmission to

position 1 (컄 page 193).

앫 On steep inclines, use the Downhill

Speed Regulation (컄 page 264).

앫 Utilize the engine’s braking power to

reduce vehicle speed. If this is insufficient, apply the brakes gently. Make sure the vehicle is moving in the line of gravity.

앫 Check the brakes after a lengthy down-

grade drive.

i The special Off-road – ABS (컄 page 97) set- ting allows for precise and brief (cyclical) block- ing of the front wheels, permitting them to dig into loose ground. Remember that, when stopped, the front wheels slide across a surface and thus lose their ability to steer the vehicle.

Operation Driving instructions

! The water depth must not exceed the respective value listed in the table. The ground under the water might not be firm which could result the water being deeper than expected when driving the vehicle through it. Please note that the water level is correspondingly lower for flowing water. 앫 Vehicles with air suspension package*:

Select the highest vehicle level possible (컄 page 270).

앫 Switch to off-road driving program

(컄 page 268) before driving through water.

앫 Shift automatic transmission to

앫 Avoid high engine speeds. 앫 Enter and leave 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.

! Do not open any of the vehicle’s doors while driving through water. Water could otherwise en- ter the vehicle interior and damage the vehicle’s electronics, as well as the interior equipment. 앫 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 Make sure that only small bow waves

are formed when driving the vehicle through water.

앫 Clean mud off the tire tread after driv-

ing through water.

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

! Obstacles can damage the vehicle underbody or suspension components. If possi- ble use the assistance of a second person out- side the vehicle to scout the path you intend to take and check for adequate ground clearance when you cross obstacles with your vehicle. The person assisting you outside the vehicle should always be a safe distance away from the vehicle and positioned so that he or she cannot get hurt in case of any unexpected vehicle movement. After off-road driving or crossing obstacles, in- spect vehicle for any damage, especially vehicle underbody and suspension components. Failure to do so can adversely affect the vehicle’s future performance, including increased chance of an accident.

339

Operation Driving instructions

When driving over tree stumps, big rocks and other obstacles, observe the following rules: 앫 Make sure the off-road driving program

(컄 page 268) is switched on.

앫 Avoid high engine speeds. 앫 Shift automatic transmission to

position 1 (컄 page 193).

앫 Check the vehicle clearance before

crossing obstacles.

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.

! 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.

Driving on sand

Warning!

Do not reduce the tire inflation pressure before driving through sand. However, if you do so, remember to correct the tire inflation pressure (컄 page 375) before continuing your trip. Driving with reduced tire inflation pressure increases the risk of losing control of the vehicle and rolling over.

When driving on sand, observe the follow- ing rules: 앫 Vehicles with air suspension package*:

Set the raised level (컄 page 270).

앫 Avoid high engine speeds. 앫 Shift automatic transmission into a

gear range that is appropriate for the terrain.

앫 In sandy soil, drive at a steady speed as allowed by conditions. This helps over- come the vehicle rolling resistance and reduce the likelihood of the vehicle sinking into the ground.

앫 Drive in tracks of other vehicles if they are not too deep and if you have suffi- cient clearance.

Ruts A number of off-road tracks or other by- ways have deep ruts which can cause the underbody to come in contact with the ground. 앫 Make sure the off-road driving program

(컄 page 268) is switched on.

앫 Vehicles with air suspension package*:

Set the raised level (컄 page 270).

340

! Check that the ruts are not too deep and your vehicle’s clearance is sufficient. Otherwise: 앫 your vehicle may be damaged 앫 the underbody of the vehicle may come in contact with the ground and you may get stuck

앫 Avoid high engine speeds. 앫 Shift automatic transmission to

position 1 (컄 page 193).

앫 Drive next to the ruts rather than

through them if at all possible.

앫 If the ruts are too deep to drive in, drive

with one side of the vehicle on the grassy center strip if the route permits.

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.

Damage to the vehicle may influence driving comfort and pose the risk of accident to you and other drivers.

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 off-road driving program

(컄 page 268).

앫 Switch off the DSR (컄 page 265). 앫 Vehicles with air suspension package*:

Lower the vehicle back to a level suitable for road conditions, e.g. High- way/High-speed level (컄 page 270).

Vehicle and trailer weights and ratings Gross Vehicle Weight Rating (GVWR) is the maximum permissible vehicle weight: ML 350, ML 500, ML 320 CDI: 6239 lbs (2830 kg) ML 63 AMG: 6393 lbs (2900 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:

ML 350, ML 320 CDI

ML 500 ML 63

AMG

Front 2943 lbs (1335 kg) 3296 lbs (1495 kg)

Rear

2987 lbs (1355 kg) 3252 lbs (1475 kg)

3175 lbs (1440 kg) 3527 lbs (1600 kg)

The Gross Trailer Weight (GTW) is the weight of the trailer plus the weight of all cargo, equipment, luggage etc. loaded on the trailer. The maximum permissible gross trailer weight to be towed: 4982 lbs (2260 kg) Trailer Tongue Weight Rating (TWR) is the maximum permissible weight on the trailer tongue: 496 lbs (225 kg) limit for Mercedes-Benz approved hitch receiver.

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.

i We recommend loading the trailer in such a manner that it has a Tongue Weight (TW) between 10% and 15% of the Gross Trailer Weight (GTW).

i Maximum trailer ratings are calculated as- suming a base vehicle, plus any options neces- sary to achieve the rating, plus driver. The weight of other equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow.

343

Operation Driving instructions

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 Gross Trailer Weight (GTW) and Tongue Weight (TW). The values as measures must not exceed the weight limits listed under “Vehicle and trailer weight and ratings” (컄 page 343).

Attaching a trailer

Warning!

While you are coupling or decoupling a trail- er, make sure that you do not 앫 lock or unlock 앫 open or close a vehicle door or the tailgate. The vehicle’s level could change and you could endanger yourself and/or others as a result.

Make sure that you do not operate the ADS button* (컄 page 269) or the vehicle level control system* (컄 page 270) when cou- pling/decoupling the 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 criss-crossed under the trailer tongue. They must be attached to the hitch receiver, and not to the vehicle’s bumper or axle. Make 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. Check with your local state laws for specific requirements. The switch activates the trailer brakes in the possible event that the trailer might separate from the tow vehicle.

344

! 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 function properly.

i The provided vehicle electrical wiring harness for trailer towing has a brake signal wire for hook-up to a brake controller. You should consider using a trailer sway control system. For further information, see an authorized Mercedes-Benz Light Truck Center. 왘 Make sure the automatic transmission

is set to P (컄 page 187).

왘 Set the parking brake for the vehicle

(컄 page 65).

왘 Start the engine (컄 page 54). 왘 Vehicles with air suspension package*:

Set the vehicle level to Highway (컄 page 270).

왘 Vehicles with air suspension package*:

Set the ADS* to AUTO or COMFORT (컄 page 269).

왘 Turn off the engine (컄 page 66). 왘 Close all doors and the tailgate. 왘 Attach the trailer. 왘 Plug in all electrical connectors.

i Vehicles with air suspension package*: When you are towing a trailer, the vehicle level always remains in the Highway setting. The following applies additionally when towing a trailer: 앫 The vehicle is lowered to the highway level when it reaches a speed of 5 mph (8 km/h) if not set to highway level.

앫 The high-speed level is not available. The restrictions that apply to towing also apply when using accessories that are connected to the trailer power socket, such as a bicycle rack.

Operation Driving instructions

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

345

Operation Driving instructions

앫 Adjust the mirrors (컄 page 49) 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 make 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 make sure 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.

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 cross wind gusts, and requires more sensi- tive 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, reduce the vehicle’s speed immediately. In no case attempt to straighten out the tow vehicle and trailer by increasing the speed. 앫 If the transmission repeatedly shifts between gears on inclines, manually shift to a lower gear (select 4, 3, 2 or 1) (컄 page 193). 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 automatic transmission in 1, switch on off-road driving program (컄 page 268).

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.

앫 If the engine coolant rises to an ex-

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.

346

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.

Operation Driving instructions

Uncoupling the trailer

Warning!

왘 Start the engine (컄 page 54). 왘 Close all doors and the tailgate. 왘 Set the parking brake for the trailer.

Vehicles with air suspension package*:

While you are coupling or decoupling a trail- er, make sure that you do not 앫 lock or unlock 앫 open or close a vehicle door or the tailgate. The vehicle’s level could change and you could endanger yourself and/or others as a result.

Make sure that you do not operate the ADS button* (컄 page 269) or the vehicle level control system* (컄 page 270) when cou- pling/decoupling the trailer.

왘 Make sure the automatic transmission

is set to P (컄 page 187).

왘 Set the parking brake for the vehicle

(컄 page 65).

Warning!

Vehicles with air suspension package*:

As soon as you disconnect the electrical connection between the trailer and the vehicle, the vehicle will lower. To help avoid personal injury, make sure no one is near the wheel housing or underneath the vehicle before the electrical connection is discon- nected.

When you uncouple the trailer, the vehicle is temporarily raised because the springs are relieved of load. Be especially careful during this process, as you could otherwise injure yourself and/or others. Make sure that any persons remaining in the vehicle do not press the switches for vehicle level control or the ADS*.

347

Operation Driving instructions

Passenger compartment

The rear cargo compartment is the preferred place to carry objects. Always use tie down rings, and if so equipped, always use parti- tion net* when transporting cargo. The par- tition net* cannot secure hard or heavy objects. Always fasten items being carried as securely as possible using the cargo tie-down rings in the cargo floor area and fastening materials.

Warning!

Driving abroad

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.

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 directory, you should request pertinent information from an authorized Mercedes-Benz Light Truck Center.

Control and operation of radio transmitters

COMAND system, radio and telephone*

Warning!

Do not forget that your primary responsibili- ty is to drive the vehicle. Only operate the COMAND system, radio or telephone1 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.

1 Observe all legal requirements.

348

Telephones and two-way radios

Catalytic converter (gasoline engine)

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, possibly resulting in an accident and/or personal injury.

Radio transmitters, such as a portable telephone or a citizens band unit should only be used inside the vehicle if they are connected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation instructions regarding use of an external antenna.

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 Maintenance Booklet.

! To prevent damage to the catalytic convert- ers, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, exces- sive unburned fuel may reach the catalytic con- verter, causing it to overheat and potentially start a fire.

Operation Driving instructions

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.

Oxidation catalyst (diesel engine)

Your vehicle is equipped with an oxidation catalyst, an important element in conjunc- tion with the oxygen sensors to achieve substantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by following our recommended maintenance instruc- tions as outlined in your Maintenance Booklet.

349

Coolant temperature

During severe operating conditions, e.g. stop-and-go traffic, the coolant tem- perature may rise close to approximately 248°F (120°C). The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious en- gine damage which is not covered by the Mercedes-Benz Limited Warranty.

Operation Driving instructions

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 limits required by law. 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. Moreover, the specified service jobs must be carried out regularly accord- ing to Mercedes-Benz servicing require- ments. For details refer to the Maintenance Booklet.

Warning!

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause un- consciousness and possible 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.

350

Warning!

앫 Driving when your engine is overheated can cause some fluids, which may have leaked into the engine compartment to catch fire. You could be seriously burned.

앫 Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.
