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 multifunction display for approximately 5 seconds. The corresponding cruise control speed segments from the selected speed to the vehicle maximum speed in the multifunction display are illuminated. G Warning! The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always 172 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. 1 Setting current or higher speed 2 Setting current or lower speed 3 Canceling the cruise control 4 Resume to last set speed Activating cruise control You can activate the cruise control at a vehicle speed above 20 mph (30 km/h). You cannot activate the cruise control: Rwhen you brake Rwhen you have engaged the parking brake Rwhen the automatic transmission is in park position P, reverse gear R, or neutral position N Rthe ESP® is switched off or has switched off due to a malfunction The vehicle speed displayed in the speedometer can briefly vary from the speed setting for the cruise control system. Setting current speed X Accelerate or decelerate to the desired speed. X Briefly lift the cruise control lever in direction of arrow 1 or press in direction of arrow 2. X Remove your foot from the accelerator pedal. i On uphill or downhill grades, the cruise control may not be able to maintain the set speed. Once the grade eases, the set speed will be resumed. On downhill grades, the cruise control maintains the set speed by braking with the vehicle’s brake system. In addition, on longer downhill grades the automatic transmission will downshift automatically. Canceling cruise control X Depress the brake pedal. or X Briefly push the cruise control lever in direction of arrow 3. The last set speed is stored for later use. The last stored speed is deleted from memory when the engine is turned off. The cruise control switches off automatically when you depress the brake pedal or you engage the parking brake. In this case, the cruise control speed segments in the multifunction display will go out. The cruise control also switches off automatically when Rthe vehicle speed falls below 20 mph (30 km/h) Rthe ESP® is in operation Rthe ESP® is switched off with the ESP® switch Controls in detail Driving systems Rthe ESP® has switched off due to a malfunction Ryou shift the automatic transmission into neutral position N while driving The cruise control speed segments in the multifunction display goes out and an acoustic warning will sound. 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. 173 Controls in detail Driving systems 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. X Lift the cruise control lever in direction of arrow 1 and hold it up to increase, or press the cruise control lever in direction of arrow 2 and hold it down to decrease, until the desired speed is reached. X Release the cruise control lever. The new speed is set and the vehicle will accelerate or decelerate. Fine adjustment in 1 mph (Canada: 1 km/h) increments X Briefly tip the cruise control lever in direction of arrow 1 to increase or in direction of arrow 2 to decrease. Resume last stored speed G Warning! The set speed stored in memory should only be set again if prevailing road conditions and legal speed limits permit. Possible acceleration or deceleration differences arising from returning to the preset speed could cause an accident and/ or serious injury to you and others. 174 X Briefly pull the cruise control lever in direction of arrow 4. in the front bumper and four sensors in the rear bumper. X Remove your foot from the accelerator pedal. The last stored speed is deleted from memory when the engine is turned off. 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 switch on the ignition and the 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. The Parktronic system monitors the surroundings of your vehicle with six sensors 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 270). 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. Range of the sensors Front sensors Center Corners approx. 40 in (100 cm) approx. 24 in (60 cm) Controls in detail Driving systems Rear sensors Center Corners approx. 48 in (120 cm) approx. 32 in (80 cm) Minimum distance Center Corners approx. 8 in (20 cm) approx. 6 in (15 cm) If the Parktronic system detects an obstacle in this range, all the distance warning segments illuminate and you hear a warning signal. If the obstacle is closer than the minimum distance, the actual distance may no longer be indicated by the Parktronic system. Warning indicators Visual signals indicate to the driver the relative distance between the sensors and an obstacle. 175 Controls in detail Driving systems Front area warning indicator 1 Left side of the vehicle 2 Right side of the vehicle Rear area warning indicator (coupe/cabriolet) 1 Left side of the vehicle 2 Right side of the vehicle 176 Each warning indicator is divided into six yellow and two red distance segments for either side of the vehicle.

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 (Y page 184) is deactivated. G Warning!
