RSide marker lamps G Warning! If the exterior lamp switch is set to U, the headlamps will not automatically come on under foggy conditions. To minimize risk to you and to others, activate headlamps by turning exterior lamp switch to B when driving or when traffic and/or ambient lighting conditions require you to do so.

In low ambient lighting conditions, only switch from position U to B with the vehicle at a standstill in a safe location. Switching from U to B will briefly switch off the headlamps. Doing so while driving in low ambient lighting conditions may result in an accident. The automatic headlamp feature is only an aid to the driver. The driver is responsible for the operation of the vehicle’s lights at all times.

X Switching on: Turn the exterior lamp

switch to position U. With the SmartKey in starter switch position 1 or the KEYLESS-GO start/stop button pressed once, the tail and parking lamps, the license plate lamps and the side marker lamps will come on and go out depending on the brightness of the ambient light. When the engine is running the low-beam headlamps, the tail and parking lamps, the license plate lamps and the side marker lamps will come on and go out depending on the brightness of the ambient light.

Canada only: High-beam headlamps are only available with the exterior lamp switch in position B.

Daytime running lamp mode In Canada, the daytime running lamp mode is mandatory and therefore in a constant mode. In the USA, the daytime running lamp mode is deactivated by default. Activate the daytime running lamp mode using the control system, see “Setting daytime running lamp mode (USA only)” (Y page 136). X Turn the exterior lamp switch to position

With the daytime running lamp mode activated and the engine running, you cannot switch off the low-beam headlamps manually.

Canada only With the exterior lamp switch in position M or U, you cannot switch on the high- beam headlamps. The high-beam flasher is available at all times. For nighttime driving turn the exterior lamp switch to position B to permit activation of the high-beam headlamps. When the engine is running, and you Rshift from a driving position to park position P with the vehicle at a standstill, the low- beam headlamps will go out with a delay of 3 minutes

X Turn the combination switch in direction of

arrow 2 to the desired position, depending on the intensity of the rain.

Intermittent wiping Only switch on intermittent wiping under wet weather conditions or in the presence of precipitation. When you select intermittent wiping, the rain sensor is activated. The rain sensor sets a suitable wiping interval depending on the wetness of the sensor surface automatically. ! Do not leave windshield wipers on an intermittent setting when the vehicle is taken to an automatic car wash or during windshield cleaning. Windshield wipers will operate in the presence of water sprayed

102

on the windshield, and windshield wipers may be damaged as a result.

! If you have set intermittent wiping, dirt on

the surface of the rain sensor or optical effects may cause the windshield wipers to wipe in an undesired fashion. This could then damage the windshield wiper blades or scratch the windshield. You should therefore switch off the windshield wipers when weather conditions are dry.

Intermittent wiping interval is dependent on wetness of windshield. After the initial wipe, pauses between wipes are controlled by the rain sensor automatically. X Turn the combination switch to position I. Intermittent wiping is interrupted when the vehicle is at a standstill and a door is opened. This protects persons getting into or out of the vehicle from being sprayed. Intermittent wiping will be continued when all doors are closed and Rthe automatic transmission is in drive

position D or reverse gear R or

Rthe wiper setting is changed using the

combination switch

Single wipe X Press the combination switch briefly in direction of arrow 1 to the resistance point. The windshield wipers wipe one time without washer fluid.

Wiping with washer fluid X Press the combination switch in direction

of arrow 1 past the resistance point. The windshield wipers operate with washer fluid.

i To prevent smears on the windshield or noisy/chattering wiper blades, wipe with washer fluid every now and then even when it is raining.

For information on filling up the washer reservoir, see “Washer system and headlamp cleaning system” (Y page 233). For information on cleaning the headlamps with washer fluid, see “Headlamp cleaning system” (Y page 99).

Starting the engine 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.

Driving and parking Safety notes 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 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. G 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 vehicle. Adapt your driving accordingly.

Driving off 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.

! Do not run cold engine at high engine speeds. Running a cold engine at high engine speeds may shorten the service life of the engine. This is not covered by the Mercedes-Benz Limited Warranty. CLK 63 AMG: At engine temperatures below 68‡ (20†), the engine’s maximum speed is restricted in order to protect it from damage. Avoid driving your vehicle at full speed when the engine is cold to prevent premature engine wear and/or diminished comfort.

Effect

ì Park position

Shift the automatic transmission into park position P only when the vehicle is stopped. The park position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always engage the parking brake in addition to shifting the automatic transmission into park position P to secure the vehicle. The SmartKey can only be removed from the starter switch with the gear selector lever in park position P. With the SmartKey removed from the starter switch, the gear selector lever is locked in park position P. If the vehicle’s electrical system is malfunctioning, the gear selector lever could remain locked in park position P. To unlock the gear selector lever manually, see “Manually unlocking the gear selector lever” (Y page 321).

í Reverse gear

Effect

ë Neutral position

No power is transmitted from the engine to the drive axle. When the brakes are released, the vehicle can be moved freely (pushed or towed). To avoid damage to the transmission, never shift the automatic transmission into neutral position N while driving. Exception: If the ESP® is deactivated or malfunctioning, shift the automatic transmission into neutral position N if the vehicle is in danger of skidding. ! Coasting the vehicle, or

driving for any other reason with the automatic transmission in neutral position N can result in transmission damage that is not covered by the Mercedes-Benz Limited Warranty.

X Shift the automatic transmission from

current gear 1 into the next higher gear. The fuel supply will otherwise be interrupted to prevent the engine from overrevving.

Controls in detail

Instrument cluster

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. During severe operating conditions, e.g. stop- and-go traffic, the coolant temperature may rise close to 248‡ (120†). ! Excessive coolant temperature triggers a warning in the multifunction display and the red coolant temperature warning lamp D in the instrument cluster comes on. The engine should not be operated with a coolant temperature above 248‡ (120†). Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.
