For your safety and the safety of others, we recommend that you pull over to a safe location and stop before placing or taking a telephone call. If you choose to use the telephone while driving, please use the hands-free device and only use the telephone when weather, road and traffic conditions permit. Some jurisdictions prohibit the driver from using a mobile phone while driving a vehicle. 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. Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunction of the vehicle’s electronic system, possibly resulting in an accident and/or personal injury.

Driving systems

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

Observe additional messages in the multifunction display that may appear. 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.

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

and

Rrelease the parking brake

and

Rthe automatic transmission is in 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 switches on again. The Parktronic system also deactivates when you shift the automatic transmission into park position P or engage the parking brake. The Parktronic system monitors the surroundings of your vehicle with six sensors in the front bumper and four sensors in the rear bumper.

170

1 Sensors in the front bumper To function properly, the sensors must be free of dirt, ice, snow and slush. Clean the sensors regularly, being careful not to scratch or damage the sensors, see “Cleaning the Parktronic system sensors” (Y page 294). 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.

! Special attention must be paid to objects

with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such objects may not be detected by the system and can damage the vehicle. During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. street curbs, painted posts, or trailer hitches etc.). The Parktronic system will not detect such objects at close range and damage to your vehicle or the object may result.

! Ultrasonic signals from outside sources

(e.g. truck air brakes, car wash, or jackhammers) may impair the operation of the Parktronic 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. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (Y page 182).

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 127). 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.

Notes on 3-zone automatic climate control With the help of a sun sensor, the automatic climate control determines the relation of the sun to the vehicle and automatically adjusts the inside temperature for every individual zone. The automatic climate control is operational whenever the engine is running. It cools the vehicle’s interior according to the angle and intensity of the sun’s rays, the outside temperature and the selected temperature. You can operate the automatic climate control in either the automatic or manual mode. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. G Warning!
