Important notes on use
To function properly, BlueTEC exhaust gas aftertreatment must be operated with the reducing agent DEF.
When the supply of DEF is almost used up, the Check Additive See Operator's Manual message is shown in the multifunction display.
When the DEF supply drops to a minimum, the Remaining Starts: 16 message is shown in the multifunction display.
If the Remaining Starts: 16 message appears in the multifunction display, you can start the engine another 16 times. If DEF is not refilled, you will subsequently be unable to start the engine. Refill the DEF tank with approximately 1 gal (3.8 l) DEF. Have the DEF tank refilled at a qualified specialist workshop.
i If you drive the vehicle faster than
10 mph (16 km/h), the Check Additive See Operator's Manual message goes out after approximately one minute.
If the outside temperature is below 12 ‡ (Ò11 †) it may be difficult to top up. If DEF is frozen and there is an active warning indicator, it may not be possible to add DEF. Park the vehicle in a warmer place, e.g. in a garage, until DEF has become fluid again. It will then be possible to add DEF again. Alternatively, have the DEF tank refilled at a qualified specialist workshop.
Further information about BlueTEC exhaust gas aftertreatment and DEF is available at any authorized Mercedes-Benz Center.
procedure
DEF is a water-soluble fluid for the exhaust gas aftertreatment of diesel engines. It is:
Rnot poisonous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are particularly irritating to the skin, to mucous membranes and to the eyes. You may experience a burning sensation in your eyes, nose and throat. Coughing and watering of the eyes are possible.
Do not inhale ammonia vapors. Fill the DEF tank only in well-ventilated areas.
DEF must not come into contact with your skin, eyes or clothing and must not be swallowed. Keep DEF away from children.
If you or other persons come into contact with DEF, observe the following:
RRinse DEF from your skin immediately with
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical assistance without delay.
RIf DEF has been swallowed, rinse your
mouth out immediately. Drink plenty of water. Seek medical assistance without delay.
RChange out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with DEF, and do not dilute DEF with water. This may destroy the BlueTEC exhaust gas aftertreatment system.
! The vehicle must be parked on level
ground to fill the DEF tank. The DEF tank can only be filled as intended with the vehicle parked on a level surface. This avoids false level readings. Filling the tank
182 Refueling
is not permitted if the vehicle is not parked on a level surface. There is a danger of overfilling, which could result in damage to components of the BlueTEC exhaust gas aftertreatment.
! Rinse surfaces that have come into
contact with DEF immediately with water or remove DEF using a damp cloth and cold water. If the DEF has already crystallized, use a sponge and cold water to clean it. DEF residues crystallize after time and contaminate the affected surfaces.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to the fuel tank, this can lead to engine damage.

Driving tips
General notes
Important safety notes
G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
G WARNING If you operate mobile communication equipment while driving, you will be distracted from traffic conditions. You could also lose control of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle is stationary.
Observe the legal requirements for the country in which you are driving. Some jurisdictions prohibit the driver from using a mobile phone while driving a vehicle.
If you make a call while driving, always use hands-free mode. Only operate the telephone
when the traffic situation permits. If you are unsure, pull over to a safe location and stop before operating the telephone.
Bear in mind that at a speed of only 30 mph (approximately 50 km/h), the vehicle covers a distance of 44 feet (approximately 14 m) per second.
Drive sensibly – save fuel
Observe the following tips to save fuel:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Maintenance Booklet or by the service interval display.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly terrain.
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.
Emission control
G WARNING Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave the engine running in enclosed spaces without sufficient ventilation.
Certain engine systems are designed to keep the level of poisonous components in exhaust fumes within legal limits.
These systems only work at peak efficiency if they are serviced 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 under 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 Maintenance Booklet.
Braking
Important safety notes
G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents.
Do not shift down for additional engine braking on a slippery road surface.
Downhill gradients
! On long and steep gradients, you must reduce the load on the brakes by shifting early to a lower gear. This allows you to take advantage of the engine braking effect and helps avoid overheating and excessive wear of the brakes.
When you take advantage of the engine braking effect, a drive wheel may not turn for some time, e.g. on a slippery road surface. This could cause damage to the

drive train. This type of damage is not covered by the Mercedes-Benz warranty.
Do not depress the brake pedal continuously while the vehicle is in motion, e.g. causing the brakes to rub by constantly applying light pressure to the pedal. This results in excessive and premature wear to the brake pads.
Heavy and light loads
G WARNING If you rest your foot on the brake pedal while driving, the braking system can overheat. This increases the stopping distance and can even cause the braking system to fail. There is a risk of an accident.
Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to the brake pads.
If the brakes have been subjected to a heavy load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after the vehicle has been washed or driven through deep water.
You then have to depress the brake pedal more firmly. Maintain a greater distance from the vehicle 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.
188 Driving tips
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance.
RBrake occasionally to remove any possible
salt residue. Make sure that you do not endanger other road users when doing so.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
! If the red brake warning lamp lights up in
the instrument cluster and you hear a warning tone while the engine is running, 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 a qualified specialist workshop.
! A function or performance test should
only be carried out on a 2-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, you could damage the drive train or the brake system.
! Because ESP® is an automatic system, the engine and ignition must be switched off (SmartKey in position 0 or 1 or Start/ Stop button in position 0 or 1) when the electric parking brake is being tested on a brake dynamometer (maximum 10 seconds).
