2010 Mercedes-benz CL Class Owners Manual

All-wheel drive (4MATIC) In vehicles with all-wheel drive (4MATIC), both axles are powered at all times when the vehicle is being operated. The 4MATIC improves traction in conjunction with the ESC (Y page 59) and the Electronic Traction System (ETS/4-ETS) (Y page 60). 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.

! Do not tow with one axle raised. Doing so could damage the transfer case, which is not covered by the Mercedes-Benz Limited Warranty. All wheels must be on or off the ground. Observe instructions for towing the vehicle with all wheels on the ground.

Parktronic system The Parktronic system is an electronic parking aid with ultrasonic sensors designed to assist the driver during parking maneuvers. The Parktronic system indicates the relative distance between the vehicle and an obstacle visually and audibly. The Parktronic system is activated automatically when Ryou switch on the ignition

and

Ryou release the electronic parking brake

or

Ryou start the engine

and

Rshift the automatic transmission into drive

position D, reverse gear R, or neutral position N

The Parktronic system deactivates at speeds above approximately 11 mph (18 km/h). At lower speeds, the Parktronic system activates again. The Parktronic system also deactivates when you shift the automatic transmission into park position P or engage the electronic parking brake and turn off the engine. The Parktronic system monitors the surroundings of your vehicle with six sensors

G Warning! The Blind Spot Assist is only a driving aid and may not detect all vehicles. The Blind Spot Assist may not be able to detect narrow vehicles such as motorcycles or bicycles, or it may not detect them until it is too late. The monitoring function may be impaired if your sensors are dirty, subject to heavy spray, or if visibility is poor due to e.g. snow, rain, or fog. This can result in vehicles not being detected or being detected too late. The Blind Spot Assist cannot detect road, traffic and weather conditions. It is the driver’s responsibility at all times to be attentive to road, weather and traffic conditions and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Failure to do so could result in recognizing dangers too late, possibly resulting in an accident and serious injury to yourself and others. In order for the Blind Spot Assist to function, the radar sensors must be switched on and operational. When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 216). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada. When you switch off the radar sensor system, the following functions are deactivated: RBlind Spot Assist RBAS PLUS (Y page 57) RPRE-SAFE® Brake (Y page 62) RDISTRONIC PLUS (Y page 304) RPark Assist (Y page 324) RAdvanced Parking Guidance (Y page 327) i USA only:

X Start the engine.

Yellow indicator lamps : in the exterior rear view mirrors come on up to a speed of 20 mph (30 km/h).

Above a speed of 20 mph (30 km/h), yellow indicator lamps : go out and the Blind Spot Assist is active. If the Blind Spot Assist detects a vehicle in its range, red warning lamp : on the corresponding side of the vehicle comes on. When you shift the automatic transmission in reverse gear R, yellow indicator lamps : in the exterior rear view mirrors goes out after approximately 3 seconds. The Blind Spot Assist is then not active.

G Warning! The Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles approaching and passing at speeds that exceed the speed of your vehicle significantly will not be detected. There will be no warning display and no audible warning. When driving in a very wide lane, the sensors may not be able to cover the entire width of the neighboring lane. Vehicles driving on the outside of the neighboring lane may not be detected. It is the driver’s responsibility at all times to be attentive to road, weather and traffic conditions and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Failure to do so could result in recognizing dangers too late, possibly resulting in an accident and serious injury to yourself and others. When driving in a very narrow lane, the sensors may detect and display vehicles in the second lane over. This will be the case if there are vehicles driving on the inside edge of their lane. The system may issue causeless warnings in the area of guardrails or similar structural boundaries. The Blind Spot Assist sensors are built into the front and rear bumpers. Make sure that

340 Climate control system

Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Center. G Warning! Follow the recommended settings for heating and cooling given on the following pages and in the “COMAND automatic climate control” section. Otherwise the windows could fog up, impairing visibility and endangering you and others.

X 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. i If the vehicle interior is hot, ventilate the

interior before driving off, see “Summer opening feature” (Y page 283). The climate control will then adjust the interior temperature to the set value much faster. The following climate control functions can be operated via COMAND: RTemperature (Y page 194) RAir distribution (Y page 195) RAir volume (Y page 195) RSwitching off cooling (Æ) (Y page 196) RCentral climate control (Mono) (Y page 196)

Air conditioning The air conditioning is operational while the engine is running and cools the interior air to the temperature set by the operator. In addition, the air conditioning dehumidifies the interior air and helps prevent window fogging. G Warning! If you deactivate the air conditioning, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.

i Condensated water may drip out from

underneath the vehicle. This is normal and not an indication of a malfunction.

The air conditioning uses the refrigerant R134a. This refrigerant is free of CFCs which are harmful to the ozone layer.
