Effect

ì Park position

Gear selector lever position when the vehicle is parked. Place gear selector lever in position P only when vehicle is stopped. The park position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always set the parking brake in addition to placing the gear selector lever in position P to secure the vehicle.

Effect The SmartKey can only be removed from the starter switch with the gear selector lever in position P. With the SmartKey removed, the gear selector lever is locked in position P. If the vehicle’s electrical system is malfunctioning, the gear selector lever could remain locked in position P (page 352).

í Reverse gear

Place gear selector lever in position R only when vehicle is stopped.

Controls in detail Automatic transmission

Effect ë Neutral

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 trans- mission, never engage N while driving. If the ESP is deactivated or malfunctioning: Move gear selector lever to N only if the vehicle is in danger of skidding, e.g. on icy roads.

ê Drive

The transmission shifts automatically. All forward gears are available.

Controls in detail Automatic transmission

Coasting the vehicle, or driving for any other reason with gear selector lever in N can result in transmission damage that is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Getting out of your vehicle with the gear selector lever not fully engaged in position P is dangerous. Also, position P alone is not intended to or capable of preventing your vehicle from moving, possibly hitting people or objects.

Always set the parking brake in addition to shifting to position P (page 54).

When parked on an incline, turn the front wheels towards the road curb.

Do not park this vehicle in areas where combustible materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

The climate control is operational when- ever the engine is running. You can oper- ate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature and the current outside temperature.

Warning!

When operating the climate control, the air that enters the passenger compartment through the air vents in the footwell can be very hot or very cold (depending on the set temperature). This may cause burns or frost- bite on unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the footwell air vents. If necessary, change the air flow using the air distribution controls to direct the air away from the foot- well air vents (컄 page 188).

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system. The air conditioning will not engage (no cooling) if the mode ACOFF is activated or A/C is deactivated (컄 page 191).

Controls in detail Automatic climate control (CLK 500/CLK 55 AMG)

The automatic climate control is operation- al whenever the engine is running. You can operate the climate control system in ei- ther the automatic or manual mode. The system cools or heats the interior depend- ing on the selected interior temperature and the current outside temperature.

Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. The air conditioning will not engage (no cooling) if the mode ACOFF is activated or A/C is deactivated (컄 page 204).

Warning

Warning!

Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others.

When operating the automatic climate control, the air that enters the passenger compartment through the air vents in the footwell can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite on unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the foot- well air vents. If necessary change the air flow using the air distribution controls to direct the air away from the footwell air vents (컄 page 198).

196

Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled interval. A clogged filter will reduce the air volume to the interior. If the vehicle interior is hot, ventilate the interior before driving off, see “Opening (Summer opening feature)” (컄 page 253). Keep the air intake grille in front of the windshield free of snow and debris. Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window.
