Fuel consumption also increases when driving in cold weather, in stop-and-go traffic and in mountainous 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.
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.
Rolling 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 at peak efficiency if they are serviced exactly in accordance with the manufacturer's specifications. Only have work on the engine 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.

significantly influence the vehicle's consumption. The ECO display consists of three bars: RAcceleration RConstant RCoasting The percent value is the average value of the three bars. The three bars and the mean value begin at the value of 50%. A higher percentage indicates a more economical driving style. The ECO display does not provide any information on the actual consumption. A fixed percentage count in the ECO display does not indicate a fixed consumption figure in l/100 km. Apart from driving style, consumption is dependent on many factors such as, e.g.: RLoad RTire pressure RCold start RChoice of route RElectrical consumers switched on These factors are not taken into consideration by the ECO display. The evaluation of your driving style is carried out using the following three categories: Acceleration (evaluation of all acceleration)
The bar empties: Sporty acceleration
The bar fills up: Moderate acceleration, especially at high speeds
Constant (evaluation of driving style at any time)
The bar empties: Speed variations
The bar fills up: Constant speed and avoidance of unnecessary acceleration and deceleration
Coasting (evaluation of total deceleration)
The bar empties: Frequent braking
The bar fills up: Drive with care and remove your foot from the accelerator pedal in good time: the vehicle can coast without braking
i An economical driving style specially
requires driving at moderate engine speeds. Achieving a higher value in the categories "Acceleration" and "Constant": Robserve the gearshift recommendations. Rdrive in drive program E.
i On longer journeys, e.g. on highways, the
only the bar in the "Constant" category changes.
i The ECO display calculates the driving style from the start of the journey to the end. For this reason, the bars change dynamically at the beginning of the journey. On longer journeys, there are fewer changes. For more dynamic changes, carry out a manual reset.

Short journey ! Vehicles with a diesel particle filter: if the vehicle is predominantly used to travel short distances, this can lead to malfunctions in the automatic cleaning of the diesel particle filter. This can result in fuel collecting in the engine oil and causing engine failure. Therefore, if you frequently drive short distances, make sure to drive on highways or country roads for 20
minutes at least every 310 miles (500km).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.
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, but 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 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.
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 G WARNING If brake pads or brake fluid other than those recommended are 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. G WARNING Make sure that you do not endanger other road users when you apply 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. ! Vehicles with 4MATIC: function or
performance tests may 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.
! 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. 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 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.
All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Consult a qualified specialist workshop to arrange this. Have brake pads installed and brake fluid replaced at a qualified specialist workshop. If the brake system has only been subject to moderate loads, you should test the functionality of your brakes at regular intervals. To do so, press firmly on the brake pedal when driving at a high speed. This improves the grip of the brake pads. You can find a description of Brake Assist (BAS) on (Y page 67) or of BAS PLUS on (Y page 68).
AMG high-performance and ceramic brakes The AMG brake systems are 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. For this reason, it is impossible to state a mileage that will be valid under all

circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your authorized Mercedes-Benz Center. New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and braking accordingly during this break-in period. Excessive heavy braking results in correspondingly high brake wear. Observe the brake system warning lamp in the instrument cluster and note any brake status messages in the multifunction display. For high-performance driving in particular, it is important to maintain and have the brake system checked regularly.
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 may 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.
Winter driving 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. G DANGER If the exhaust pipe is blocked or adequate ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle becomes trapped in snow. There is a risk of fatal injury. If you leave the engine or the auxiliary heating running, make sure the exhaust pipe and area around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind.
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. 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.
Driving with summer tires Observe the notes in the "Winter operation" section (Y page 364).
