RParktronic system RRear view camera The ABS, BAS, EBP, ESP® and 4-ETS driving safety systems are described in the “Safety and security” section (Y page 75).

Cruise control The cruise control automatically maintains the speed you set for your vehicle. The use of the cruise control is recommended for driving at a constant speed for extended periods of time. The currently set speed or last set speed (“Resume” function) appears in the status indicator of the multifunction display: RUSA only: e.g. Cruise 55 Miles RCanada only: e.g. Ñ 90 Km/h

i The cruise control should not be activated

during off-road driving. 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. The brake pedal depresses automatically when the cruise control engages the brakes. Keep the driver’s footwell clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the cruise control system. Do not place your foot under the brake pedal – your foot could become caught.

Depressing the accelerator pedal does not deactivate the cruise control. After a brief acceleration (e.g. for passing), the cruise control will resume the last set speed.

Changing the set 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. You can increase or decrease the set speed in 1 mph (Canada: 1 km/h) increments or in 5 mph (Canada: 10 km/h) increments. When you use the cruise control lever to decelerate, the brake system will brake the vehicle automatically if the engine’s braking power does not brake the vehicle sufficiently.

Adjustment in 1 mph (Canada: 1 km/h) increments i The set speed value is increased or

decreased in 1 mph (Canada: 1 km/h) increments each time you lift or press the cruise control lever up or down to the resistance point.

X Briefly lift the cruise control lever up to the resistance point in direction of arrow 1 to increase or press the cruise control lever down to the resistance point in direction of arrow 2 to decrease.

X Release the cruise control lever.

Downhill Speed Regulation (DSR) G Warning! The Downhill Speed Regulation (DSR) is a convenience system designed to assist the driver during vehicle operation. The system must be set to be appropriate for the topographical and weather conditions encountered which can change quickly. The driver is and must remain at all times responsible for the vehicle speed and for safe brake operation. Depending on the programmed speed, actual vehicle speed and gradient, switching on the DSR while driving can cause the vehicle to slow down rapidly and you may hear a sound which is caused by the activation of the vehicle’s brake system

through the DSR. Sudden and unexpected deceleration can result in loss of vehicle control, causing an accident and/or serious personal injury to you and others. Do not switch on the DSR in a circumstance where rapid deceleration could result in a loss of vehicle control. For more information, see “Off-road driving” (Y page 275). The DSR is an aid for driving downhill. The DSR regulates your vehicle’s speed when driving downhill to the value set in the control system (Y page 159). The steeper the downhill gradient is, the greater the brake application. On flat road surfaces, the DSR brakes only slightly or not at all. The DSR regulates the vehicle’s speed in automatic transmission positions D, or R. i In addition, make use of the engine’s braking effect by shifting the automatic transmission into a lower gear.

You can drive slower or faster than the set speed at any time by braking the vehicle or depressing the accelerator pedal. i Whenever the DSR is switched on, the

DSR will use the programmed default speed to regulate the vehicle’s speed. The

default speed programmed at the factory is 4 mph (Canada: 6 km/h). The default speed can be reprogrammed using the control system (Y page 159). The next time the DSR is switched on, the DSR will use the newly programmed default speed to regulate the vehicle’s speed. Once the DSR is switched on, you can adjust the set speed using the cruise control lever (Y page 164). Keep in mind that adjusting the set speed using the cruise control lever with the DSR switched on will not change the programmed default speed. If the DSR is switched off and then switched on again, the DSR will use the programmed default speed. Depending on the road surface and level of downhill grade, the DSR may not be able to maintain the set speed. To maintain the set speed, apply the brakes if necessary.

Switching the DSR on/off

You should therefore drive downhill with particular caution as it could otherwise lead to an accident and/or serious injury to you or others. Keep in mind that as soon as you remove your foot from the accelerator pedal with the DSR switched on, the DSR will start regulating the vehicle’s speed including use of brakes if required.

Air vents G Warning! When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite to unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution adjustment to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin. For best possible performance of the climate control: X Keep the air intake grille in front of the

windshield free of snow, leaves, sticks, and any other debris.

X Always keep all air vents and grilles in the

passenger compartment free from obstruction.

i For draft-free ventilation, move the

adjustable center and side air vents to the middle position.

Climate control Notes on climate control The climate control is operational whenever the engine is running. You can operate 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. 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. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (Y page 187).

G 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. Keep the air intake grille in front of the windshield free of snow and debris. i If the vehicle interior is hot, ventilate the

interior before driving off, see “Summer opening feature” (Y page 121). The climate control will then adjust the interior temperature to the set value much faster.

Deactivating the climate control system G Warning! When the climate control system is switched off, the outside air supply and circulation are also switched off. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.

The air conditioning uses the refrigerant R134a. This refrigerant is free of CFCs which are harmful to the ozone layer. ! If the air conditioning cannot be activated

again, this indicates that the air conditioning is losing refrigerant. The compressor has turned off. Have the air conditioning checked at the nearest authorized Mercedes-Benz Center.

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 switch off the cooling function, 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.
