Distronic displays in the speedometer

When the Distronic is activated, one or two cruise control speed segments come on around set speed :. The vehicle speed displayed on the speedometer can briefly vary from the speed setting on the Distronic system.

When the Distronic detects a vehicle directly ahead, the cruise control speed segments ; appear in the speedometer. These segments represent the difference between the set speed of your vehicle : and the speed of the preceding vehicle =. If the Distronic calculates that there is a danger of collision, the distance warning lamp · in the instrument cluster comes on and an intermittent warning sounds.

X Immediately apply the brakes to avoid a

collision. Under no circumstances should the driver await the intermittent warning sound before braking. The intermittent warning sound ceases and the distance warning lamp · goes out when the necessary distance to the vehicle ahead is established again. G Warning! An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the Distronic system calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that the Distronic will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake the vehicle to increase your distance to the preceding vehicle. The warning sound is intended as a final caution in which you should intercede with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking. This will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. G Warning! The Distronic brakes your vehicle with a maximum deceleration of 6.5 ft/s2 (2 m/s2). This corresponds to approximately 20% of the maximum deceleration of your vehicle. The Distronic brakes the vehicle in an effort to restore the preset distance or to maintain the set speed.

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. G Warning! Distronic switches off and releases the brakes when the vehicle decelerates below the minimum speed of 20 mph (30 km/h) by operation of the system. At that time the driver must apply the brakes in order to reduce vehicle speed further or bring it to a stop. Depressing the accelerator pedal does not deactivate the Distronic. After a brief acceleration (e.g. for passing), the Distronic will resume the last set speed.

Setting the following distance in Distronic You can set the specified following distance for Distronic by varying the time setting between 1.0 and 2.0 seconds. Using this time setting and the current speed of your vehicle, Distronic calculates and sets the required following distance to the preceding vehicle. The set distance will be shown in the multifunction display. G Warning! It is up to the driver to exercise discretion to select the appropriate setting given road conditions, traffic, driver’s preferred driving style and applicable laws and driving recommendations for safe following distance.

X Increasing distance: Turn

thumbwheel : towards ª. Increasing the distance setting tells Distronic to maintain a greater following distance to the preceding vehicle.

X Decreasing distance: Turn

thumbwheel : towards ¥. Decreasing the distance setting tells Distronic to maintain a shorter following distance to the preceding vehicle.

Driving with Distronic This section describes a number of driving situations where special precaution is required on the part of the driver. Be prepared to brake in such situations. Braking will deactivate the Distronic system. G Warning! The Distronic works to maintain the speed selected by the driver unless a moving obstacle proceeding directly ahead of it in the same travel direction is detected (e.g. following another vehicle ahead of you at your set distance). This means that: RYour vehicle can pass another vehicle after

you have changed lanes.

RWhile in a sharp turn or if the preceding vehicle is in a sharp turn, the Distronic could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed.

219_AKB; 4; 54, en-US d2ureepe,

136 Driving systems

The Distronic regulates only the distance between your vehicle and those directly ahead of it, but does not register stationary objects in the road, e.g.: Ra stopped vehicle in a traffic jam Ra disabled vehicle Ran oncoming vehicle The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle. G Warning! The Distronic should not be used in snowy or icy road conditions. The most likely cause for a malfunctioning system is a dirty Distronic system sensor cover (located in the hood grille), especially at times of snow and ice or heavy rain. In such a case, the Distronic will switch off, and the message DISTRONIC Currently Unavailable – See Operator’s Manual appears in the multifunction display. For cleaning and care of the Distronic system sensor cover, see (Y page 219). i If the message DISTRONIC Currently Unavailable – See Operator’s Manual disappears during driving and the last set speed flashes for approximately 5 seconds, the dirt (e.g. slush) has dissolved; the Distronic works again.

A vehicle traveling in your lane but offset from your direct line of travel may not be detected by the Distronic. There will be insufficient distance to the preceding vehicle. Lane changing

The Distronic has not yet detected the vehicle changing lanes. There will be insufficient distance to the lane-changing vehicle. Narrow vehicles

In turns or bends, the Distronic may not detect a moving vehicle in front, or it may

Driving systems

137

Because of their narrow profile, the vehicles traveling near the outer edges of the lane have not yet been detected by the Distronic. There will be insufficient distance to the preceding vehicles.

Distance warning function When the Distronic is deactivated, this function will continue to warn you when recognizing a stationary obstacle or a slower vehicle moving in your vehicle’s path and the danger of a collision exists: RThe distance warning lamp · in the

instrument cluster comes on.

RAn intermittent warning will sound if

necessary.

If these warnings are issued, you must apply the brakes to maintain a safe distance and avoid a collision with the preceding vehicle. When depressing the brake pedal, the warning sound ceases. The warning sound will also cease when the distance to the preceding vehicle is sufficient again without applying the brakes. In this case, the distance warning lamp · will also go out. G Warning! If the distance warning lamp · in the instrument cluster comes on while driving and/or an intermittent warning sounds, immediate attention on the part of the driver is required. As required by the traffic situation, apply the brakes and navigate around a possible obstacle. However, do not drive by relying on the distance warning function, as this will result in an emergency braking application. This will not always enable you to avoid a collision, especially when traveling on varying road surface conditions and with varying driver reaction. Complex driving situations are not always fully recognized by the distance warning function. This could result in wrong or missing distance warnings.

X Activating/deactivating: Press

to lower without making contact with the road curb for example. Otherwise, the vehicle could be damaged.

Vehicle level control G Warning! To help avoid personal injury, keep hands and feet away from wheel housing area, and stay away from under the vehicle when lowering the vehicle chassis. Your vehicle automatically adjusts its ride height to increase vehicle safety and to reduce fuel consumption. You can choose between normal or raised level. The vehicle chassis ride height is raised or lowered according to the selected level setting and to the vehicle speed. At a speed exceeding approximately 68 mph (110 km/h) with normal level set or exceeding 75 mph (120 km/h) with raised level set, the ride height is reduced automatically. With decreasing speed, the ride height is again raised to the normal level. i These height adjustments are so small

that you may not notice any change.

Select the raised level only when required by current driving conditions. Otherwise, the handling may be impaired and the fuel consumption may increase.

! 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.

Notes on climate control system The climate control system 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. It can only function optimally when you are driving with the windows and the tilt/sliding sunroof closed. 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 146) is deactivated.

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.

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 96). 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 deactivated, the outside air supply and circulation are also deactivated. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.

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.

152 Power tilt/sliding sunroof

Do not open the tilt/sliding sunroof if there is snow or ice on the roof, as this could result in malfunctions. If you cannot open or close the tilt/sliding sunroof due to a malfunction contact Roadside Assistance or an authorized Mercedes-Benz Center.

! Please keep in mind that weather

conditions can sometimes change rapidly. Make sure to close the tilt/sliding sunroof when leaving the vehicle. If water enters the vehicle interior, vehicle electronics could be damaged which is not covered by the Mercedes-Benz Limited Warranty.

i You can also open or close the tilt/sliding

sunroof using the SmartKey or the KEYLESS-GO function, see “Summer opening feature” (Y page 96) and “Convenience closing feature” (Y page 96).

i After switching off the ignition or

removing the SmartKey from the starter switch, you can operate the tilt/sliding sunroof until you open the driver’s or front passenger door. If no door was opened you can operate the tilt/sliding sunroof for up to 5 minutes.

Power tilt/sliding sunroof Opening and closing G Observe Safety notes, see page 52. G Warning! When opening or closing the tilt/sliding sunroof, make sure there is no danger of anyone being harmed by the opening/closing procedure. The tilt/sliding sunroof is equipped with the express operation and automatic reversal function. If the movement of the tilt/sliding sunroof is blocked during the closing procedure, the tilt/sliding sunroof will stop and open slightly. The tilt/sliding sunroof operates differently when the sunroof switch is pressed and held. See the “Closing when the tilt/sliding sunroof is blocked” section for details. The opening/closing procedure of the tilt/ sliding sunroof can be immediately halted by releasing the sunroof switch or, if the sunroof switch was moved past the resistance point and released, by moving the sunroof switch in any direction. G Warning! The tilt/sliding sunroof is made out of glass. In the event of an accident, the glass may shatter. This may result in an opening in the roof. In a vehicle rollover, occupants not wearing their seat belts or not wearing them properly may be thrown out of the opening. Such an opening also presents a potential for injury for occupants wearing their seat belts properly as entire body parts or portions of them may protrude from the passenger compartment.

! To avoid damaging the seals, do not transport any objects with sharp edges which can stick out of the tilt/sliding sunroof.
