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.

Brakes Important safety notes 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.

152 Driving tips

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 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 an authorized Mercedes-Benz Center.

All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. This work should be carried out at 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 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

the front axle raised.

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 will give the brake pads better grip.

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 62).

High-performance brake system for AMG vehicles The high-performance brake system is only installed on the C 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.

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.

Winter driving General information 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 155).

Winter tires At temperatures below 45 ‡(+7 †), use winter tires or all-season tires. Both types of tire are identified by the M+S marking. 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 driving safety systems such as ABS and ESP® 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 mounted. Once you have installed the winter tires: X Check the tire pressures (Y page 275). X Restart the tire pressure monitor

(Y page 277). 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. ! 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 63) 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 Vehicles with manual transmission: engage

neutral.

X Vehicles with automatic transmission: shift

the transmission to position N.

i For more information on driving with

snow chains, see (Y page 154). G Warning Make sure that you do not endanger other road users when you apply the brakes.

in the "Service24h" section of the Service Booklet.

Driving systems Cruise control Important safety notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must shift to a lower gear in good time or select shift range 1, 2 or 3 in vehicles with automatic transmission. By doing so, you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 20 mph (30 km/h). G Warning The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle's speed and for safe brake operation. Only use the cruise control if the road, traffic, and weather conditions make it advisable to travel at a constant speed. RThe use of the cruise control can be

dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed.

RThe use of the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.

RDeactivate the cruise control when driving

in fog.

The "Resume" function should only be operated if the driver is fully aware of the

previously set speed and wishes to resume this particular preset speed. G Warning! The cruise control brakes automatically so that the set speed is not exceeded.

i Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Cruise control maintains the stored speed on downhill gradients by automatically applying the brakes.

i Vehicles with manual transmission: RAlways drive at adequate, but not

excessive, engine speeds. RChange gear in good time. RIf possible, do not change down several

gears at a time.

Storing the current speed or calling up the last stored speed G Warning The set speed stored in memory should only be set again if prevailing road conditions and legal speed limits permit. Possible acceleration or deceleration differences arising from returning to the preset speed could cause an accident and/or serious injury to you and others.

X Briefly pull the cruise control lever towards

you ?.

X Remove your foot from the accelerator

pedal. The first time cruise control is activated, it stores the current speed or regulates the speed of the vehicle to the previously stored speed.

Setting a speed G Warning Keep in mind that it may take a brief moment until the vehicle has made the necessary adjustments. Increase or decrease the set vehicle speed to a value that the prevailing road conditions and legal speed limits permit. Otherwise, sudden and unexpected acceleration or deceleration of the vehicle could cause an accident and/ or serious injury to you and others.

4MATIC (permanent four-wheel drive) 4MATIC ensures that all four wheels are permanently driven. Together with ESP®, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip. G Warning! If a drive wheel is spinning due to insufficient traction: RWhile driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The 4MATIC cannot prevent accidents resulting from excessive speed.

! Never tow the vehicle with one axle

raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground.

i In wintry driving conditions, the maximum

effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary.

PARKTRONIC Important safety notes i PARKTRONIC is only available in Canada. G Warning! The PARKTRONIC is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always remains with the driver.

G Warning! Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured.

PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is activated automatically when you: Rswitch on the ignition. Rshift the transmission to position D, R or

N on vehicles with automatic transmission.

Rrelease the parking brake. PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.

G Warning A driver's attention to the road and traffic conditions must always be his/her primary focus when driving. For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely. 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. G Warning! No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired.

If you must continue to drive, do so with added caution. Contact an authorized Mercedes- Benz Center as soon as possible. G Warning Malfunction and warning messages are only indicated for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.

Displays and operation Coolant temperature gauge G Warning 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. 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. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

The coolant temperature gauge is in the instrument cluster on the right-hand side. Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †). ! If the coolant temperature is too high a

display message is shown.

Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as

this could damage the engine.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display The outside temperature display is in the multifunction display. 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.

Changes in the outside temperature are displayed after a short delay.

Speedometer with segments The segments in the speedometer indicate which speed range is available. Cruise control mode: The segments light up from the stored speed to the maximum speed.

Operating the on-board computer The on-board computer is activated as soon as you turn the SmartKey to position 1 in the ignition lock. You can control the multifunction display and the settings in the on-board computer using
