You may otherwise not receive all necessary safety information and warning for the operation of your vehicle. G Warning! Do not fill diesel tanks with gasoline. Do not mix diesel fuel with gasoline. Otherwise the fuel system and engine could be damaged. In addition, the vehicle could catch fire.

! Do not use gasoline to refuel vehicles with a diesel engine. Do not use diesel to refuel vehicles with a gasoline engine. Even small amounts of the wrong fuel result in damage to the fuel system and engine.

! Do not start the engine if you accidentally refuel with the wrong fuel. Otherwise, the fuel could enter the fuel lines. This would require draining of the fuel tank and fuel lines. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely.

Gasoline Fuel grade ! You should only refuel with unleaded premium-grade gasoline as this avoids damaging the catalytic converter. If engine running problems are apparent, have the cause checked immediately and repaired. Excess unburned fuel can otherwise enter the catalytic converter, leading to overheating and possibly causing a fire.

i Only refuel with unleaded premium-grade gasoline with a specified minimum octane number of 91 (average value of 96 RON/ 86 MON). Usually you will find information about the fuel grade on the pump. If you cannot find

the label on the gasoline pump, ask the gas station staff. You can find further information under "Fuel" (Y page 358), by consulting an authorized Mercedes-Benz Center or visiting http://www.mbusa.com (USA only).

Diesel Fuel grade ! Only refuel with ULTRA-LOW SULFUR DIESEL FUEL (ULSD, 15 ppm SULFUR MAXIMUM). Using other diesel fuels could result in increased wear and damage to the engine and/or exhaust system. Never refuel with marine diesel or heating oil. Do not mix these fuels with diesel fuels and do not use any special additives, as this may result in damage.

! When refueling using a fuel can, use a

filter or use a clean cloth as a filter. Otherwise, particles from the fuel can may block the fuel lines and/or the diesel injection system.

i Refuel only with ULTRA-LOW SULFUR DIESEL FUEL (ULSD, 15 ppm SULFUR MAXIMUM). Usually you will find information about the fuel grade on the pump.

160 Driving tips

Driving tips General driving tips Important safety instructions G Warning! Please do not forget that your primary responsibility 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 recommend that you pull over to a safe location and stop before placing or taking a telephone call. If you choose to use the telephone26 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 mobile telephone while driving a vehicle. Only operate the COMAND26 (Cockpit Management and Data System) if road, weather and traffic conditions permit. Otherwise, you may not be able to observe traffic conditions and could endanger yourself and others. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximately 14 m) every second.

Drive sensibly – save fuel To save fuel, observe the following notes: X Keep tires at the recommended inflation

pressures.

X Remove unnecessary cargo. X Remove the roof carrier when not in use. X Maintain a low engine speed until the

engine is warm.

X Avoid frequent acceleration and

deceleration.

X Have all maintenance work performed at

the service intervals specified in the

26 Observe all legal requirements.

Service Booklet or indicated by the service interval indicator.

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

Drinking and driving G Warning Drinking and driving and/or taking drugs and driving are very dangerous combinations. 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.

Pedals G Warning Make sure absolutely no objects are obstructing the pedals' range of movement. Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure that the pedals still have sufficient clearance. During sudden driving or braking maneuvers, the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.

Coasting with the engine switched off G Warning! There is no power assistance for the steering and the brake when the engine is not running. Steering and braking requires significantly more effort and you could lose control of the vehicle and cause an accident as a result.

Do not turn off the engine while the vehicle is in motion.

Exhaust check G Warning Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness 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 window fully open at all times.

Certain engine systems are designed to keep the level of poisonous components in exhaust fumes within legal limits. These systems only work optimally if they are maintained exactly in accordance with the manufacturer's specifications. For this reason, all work on the engine must be carried out by qualified and authorized Mercedes- Benz technicians. The engine settings must not be changed in any circumstances. Furthermore, all specific service work must be carried out at regular intervals and in accordance with the Mercedes-Benz service requirements. Details can be found in the Service Booklet.

Engine oil ! Vehicles with a diesel particle filter:

If the vehicle is mostly driven for short distances, it is possible that malfunctions may occur during the automatic cleaning of the diesel particle filter. This can lead to engine damage. Therefore, if you frequently drive short distances, make sure to drive on highways or country roads for 20
minutes at least every 500 km.

Brakes Important safety guidelines G Warning On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. G Warning Make sure that you do not endanger other road users when you apply the brakes.

Downhill gradients ! On long and steep gradients, you must

reduce the cargo on the brakes by shifting to a lower gear in good time. This allows you to take advantage of engine braking and helps you to avoid overheating the brakes and wearing them out excessively. When you take advantage of engine braking, a drive wheel may not turn for some time, e.g. on a slippery road surface. This could cause damage to the drive train. Such damage is not covered by the Mercedes-Benz warranty.

Heavy and light loads G Warning Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. It may also cause the brakes to overheat, seriously impairing their effectiveness. It may then not be possible to stop the vehicle in sufficient time to avoid an accident.

If the brakes have been subjected to a heavy cargo, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly.

Wet roads G Warning After driving in heavy rain for some time without applying the brakes or through water deep enough to wet brake components, the first braking action may be somewhat reduced. You have to depress the brake pedal more firmly. Maintain a safe distance from vehicles in front.

After driving on a wet road or having the vehicle washed, brake firmly while paying attention to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corrosion.

Limited braking performance on salt treated roads G Warning The layer of salt on the brake discs and the brake pads/linings may cause a delay in the braking effect, resulting in a significantly longer braking distance, which could lead to an accident. To avoid this danger, you should: Roccasionally brake carefully, without

putting other road users at risk, when you are driving on salted roads. This helps to remove any salt that may have started to build up on the brake discs and the brake pads/linings.

Rmaintain a greater distance to the vehicle

ahead and drive with particular care.

Rcarefully apply the brakes at the end of a trip and immediately after commencing a new trip, so that salt residues are removed from the brake discs.

Maintenance of the brakes ! If the brake warning lamp lights up in the instrument cluster and you hear a warning tone, even though the parking brake has been released, the brake fluid level may be

too low. Observe additional warning messages in the multifunction display. The brake fluid level may be too low due to brake pad wear or leaking brake lines. Have the brake system checked immediately. This work should be carried out at an authorized Mercedes-Benz Center.

All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Contact an authorized Mercedes-Benz Center. Only install brake pads and use brake fluid recommended by Mercedes-Benz. G 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.

! Vehicles with 4MATIC: a function or

performance test may only be carried out on a two-axle dynamometer. If you are planning to have the vehicle tested on such a dynamometer, contact an authorized Mercedes-Benz Center to obtain further information first. Otherwise, the drive train or the brake system may suffer damage.

! Vehicles with 4MATIC: as the ESP®

system operates automatically, the engine and the ignition system must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) when: Rtesting the parking brake on a brake

dynamometer.

Ryou intend to have the vehicle towed with

one of the axles raised.

Braking maneuvers triggered automatically by ESP® may seriously damage the brake system.

! Vehicles with 4MATIC: as the ESP®

system operates automatically, the engine and the ignition must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) while the parking brake is being tested on a brake dynamometer (maximum 10
seconds). Braking maneuvers triggered automatically by ESP® may seriously damage the brake system.

If your brake system is only subjected to moderate loads, you should regularly test your brake system's function by forcefully depressing the brake pedal when driving at high speed. This also improves the brake pads' friction. G Warning Make sure that you do not endanger other road users when you apply the brakes.

You can find a description of Brake Assist (BAS) on (Y page 66).

High-performance brake system for AMG vehicles The high-performance brake system is only installed on the ML 63 AMG. G 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 messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly.

The high-performance brake system is designed for heavy loads. This may lead to noise when braking. This will depend on: Rspeed Rbraking force Renvironmental conditions, such as

temperature and humidity

The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions.

Parking brake If you drive on wet roads or dirt-covered surfaces, road salt and/or dirt could get into the parking brake. In order to prevent corrosion and a reduction in the braking power of the parking brake, observe the following: Rgently depress the parking brake from time

to time before beginning the journey. Rdrive approximately 110 yd (100 m)

without exceeding a speed of 12 mph (20 km/h). G 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 on wet roads Hydroplaning If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if: Ryou drive at low speeds Rthe tires have adequate tread depth

For this reason, in the event of heavy rain or in conditions in which hydroplaning can occur you must drive in the following manner: RLower your speed RAvoid ruts RBrake carefully

Driving on flooded roads ! Do not drive through flooded areas.

Check the depth of any water before driving through it. Drive slowly through standing water. Otherwise, water may enter the vehicle interior or the engine compartment. This can damage the electronic components in the engine or the automatic transmission. Water can also be drawn in by the engine's air suction nozzles and this can cause engine damage.

i Vehicles with the AIRMATIC package: set the raised vehicle level before driving through standing water.

RRestrict the shift range to 1 or 2. RAvoid high engine speeds. REnter and exit the water at a flat place and

at a steady walking pace.

! Under no circumstances should you

accelerate before entering the water. The bow wave could cause water to enter and damage the engine and other assemblies. RDrive slowly and at an even speed through

the water.

RDo not stop. ! Do not open any of the vehicle's doors while fording. Otherwise, water could get into the vehicle interior and damage the vehicle's electronics and interior equipment.

RWater offers a high degree of resistance,

and the ground is slippery and in some cases unstable. Therefore, it is difficult and dangerous to pull away in the water.

REnsure that a bow wave does not form as

you drive.

RClean any mud from the tire tread after

fording.

RApply the brakes to dry them after fording.

Winter driving Important safety guidelines Have your vehicle winterproofed at a qualified specialist workshop, e.g. at an authorized Mercedes-Benz Center, at the onset of winter. Observe the notes in the "Winter operation" section (Y page 166).

i Vehicles with a diesel engine: do not

cover the radiator, e.g. with a protective cover. The measuring function of the Onboard Diagnosis System may otherwise provide inaccurate values. Some of these values are required by law and must therefore always be accurate.

Winter tires Use winter tires at temperatures below 45 ‡ (7 †) and on snow or ice-covered roads. Only winter tires also bearing the i snowflake symbol next to the M+S marking provide the best-possible grip in wintry road conditions. Only these tires will allow the ABS and ESP® driving systems to function optimally in winter, as these tires have been designed specifically for driving on snow. Use M+S tires of the same make and tread on all wheels to maintain safe handling characteristics. G Warning M+S tires with a tread depth of less than 1/6
inch (4 mm) must be replaced. They are no longer suitable for winter operation.

Always observe the maximum permissible speed specified for the M+S tires you have installed. Once you have installed the winter tires: X Check the tire pressures (Y page 329). X Restart the tire pressure monitor

(Y page 331). G Warning If you use your spare wheel when M+S 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 wheel replaced by a regular road wheel with an M+S tire at the nearest authorized Mercedes-Benz Center.

Snow chains For safety reasons, Mercedes-Benz recommends that you only use snow chains which have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. ! Vehicles with the Adaptive Damping

System (ADS): do not drive in ADS SPORT mode if snow chains have been mounted. The vehicle may otherwise be damaged.

! There is not enough space for snow

chains on some wheel sizes. Observe the information under "Tires and wheels" in the "Technical Data" section to avoid damage to the vehicle or the wheels.

ROnly use snow chains when driving on an area completely covered by snow. Do not exceed the maximum permissible speed of 30 mph (50 km/h). Remove the snow chains as soon as possible when you are no longer driving on snow-covered roads.

RLocal regulations may restrict the use of snow chains. Applicable regulations must be observed if you wish to mount snow chains.

RSnow chains must not be mounted on

emergency spare wheels.

If you intend to mount snow chains, please bear the following points in mind: Ryou may not attach snow chains to all

wheel-tire combinations; see the "Tires and wheels" section in the "Technical data" chapter.

Rmount snow chains only in pairs and only

on the rear wheels. Observe the manufacturer's installation instructions.

! If snow chains are mounted on the front

wheels, the snow chains could grind against the bodywork or components of the chassis. This could result in damage to the vehicle or the tires.

! Vehicles with steel wheels

If you wish to mount snow chains to steel wheels, make sure that you remove the

respective wheels' hubcaps first. The hubcaps may otherwise be damaged.

i You may wish to deactivate

ESP®(Y page 66) when pulling away with snow chains installed. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action).

Slippery road surfaces G Warning If the vehicle becomes stuck in snow, make sure 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 interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. G Warning On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control.

You should drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use cruise control. If the vehicle threatens to skid or cannot be stopped when moving at low speed: X Shift the transmission to position N.

i For more information on driving with

snow chains, see (Y page 165). G Warning Make sure that you do not endanger other road users when you apply the brakes.

Driving off-road Important safety guidelines G Warning! Grains of sand, particles of dirt and other abrasive materials can enter the brake system. This can lead to excessive wear and unpredictable braking efficiency. After the brakes have been exposed to dirty conditions, have them checked and cleaned at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. Otherwise, there is a risk that braking power may be insufficient in the event of an emergency, or that the braking effect may be unpredictable. G Warning! Do not load items on the basic carrier bars. It may cause instability during some maneuvers which could result in an accident. Drive slowly in unknown terrain. This will make it easier to recognize unexpected obstacles and avoid damage to the vehicle. To help avoid the vehicle rolling over, never turn it around on steep inclines. If the vehicle 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). 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".

G Warning! Vehicles with air suspension program: Please be aware that by raising the vehicle level, the center of gravity also rises. Therefore, always ensure that the vehicle level is as low as possible. With higher ride height the ESP® may activate earlier in certain situations. G Warning! Do not reduce the tire inflation pressure before driving through sand. However, if you do so, remember to correct the tire inflation pressure before continuing your trip. Driving with reduced tire inflation pressure increases the risk of losing control of the vehicle and rolling over.

General information Read this section before driving your vehicle off-road. Practice by traveling over more gentle off-road terrain first.
