2010 Mercedes-benz M Class Owners Manual

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.

X Decreasing distance: Turn distance

setting switch : in direction of arrow ;. 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.

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 263). i If the message DISTRONIC Available Again appears during driving, the dirt (e.g. slush) has dissolved; the Distronic works again, if you reactivate it (Y page 147).

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 detect one too soon. This may cause your vehicle to brake late or unexpectedly. Offset driving

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

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 This function warns you at a vehicle speed of above approximately 20 mph (30 km/h) in the following cases: RAt the current speed, the distance between

your vehicle and the preceding vehicle is too low for several seconds. The distance warning lamp · in the instrument cluster comes on.

RYou are gaining on a preceding vehicle rapidly. An intermittent warning sounds and the distance warning lamp · in the instrument cluster comes on.

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: Activate or

deactivate the distance warning function in the control system (Y page 137). When activated, the distance warning function indicator Ä appears in the multifunction display.

Hill-start assist system G Warning! The hill-start assist system is not designed to function as a parking brake. It does not prevent the vehicle from moving when parked on an incline. Always engage the parking brake in addition to shifting the automatic transmission into park position P. On uphill grades, the hill-start assist system maintains the pressure in the brake system for approximately 1 second after you have released the brake pedal. Therefore, you can start off smoothly without the vehicle moving immediately after releasing the brake pedal. X Depress the brake pedal. X Shift the automatic transmission into drive

Downhill Speed Regulation (DSR) For information on off-road driving, see “Off- road driving” (Y page 248). 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 138). The steeper the downhill gradient is, the greater the brake application. On flat road surfaces, the DSR brakes only slightly or not at all. 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

164_AKB; 7; 31, en-US d2ureepe,

a circumstance where rapid deceleration could result in a loss of vehicle control. 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 138). 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 142). 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

G Warning! If the accelerator pedal is depressed while the Downhill Speed Regulation (DSR) is activated, the vehicle can drive faster than the programmed set speed. 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. Depending on the programmed set speed, actual vehicle speed and gradient, the DSR can cause the vehicle to slow down rapidly. Sudden and unexpected deceleration can result in loss of vehicle control, causing an accident and/or serious personal injury to you and others. Switching on the DSR The DSR can only be switched on if the vehicle speed is below 20 mph (Canada: 30 km/h). X Press DSR switch :. Indicator lamp ; comes on. The message DSR and the set speed appear in the multifunction display.

ML 63 AMG The air suspension program is part of the ML 63 AMG standard equipment range. Due to the vehicle’s sportier suspension tuning, in comparison with standard vehicles, the level positions in the ADS settings as well as the speed thresholds for raising and lowering the vehicle have been modified. From the highway/high-speed level, the vehicle is lowered to the ADS SPORT level approximately 20 seconds after it is locked. From the raised level, the vehicle is not lowered after it is locked. When the engine is started, the previously selected setting, e.g. ADS COMF, is selected again. ! Be sure to observe this vehicle’s differing

values for ground clearance and vehicle height in comparison to standard vehicles. You could otherwise damage the vehicle. Observe the values for Ropening the tailgate Rdriving off-road Rthe vehicle’s main dimensions in the

“Technical data” section

Adaptive Damping System (ADS) The Adaptive Damping System (ADS) is controlled electronically and operates continuously. It adjusts the damping characteristics to the current operating and driving conditions. The damping is adjusted individually for each wheel. Driving safety and tire comfort are increased. The fine tuning of the damping is dependent on: Ryour driving style Rroad surface conditions Ryour personal settings

The following settings are available: RAUTO (for normal driving situations)

Indicator lamps ; and = are off.

RSPORT (for sporty driving)

X Start the engine. X Press ADS switch : repeatedly until the

desired suspension tuning is reached.

The setting remains stored when you turn off the engine.

Vehicle level control Your vehicle automatically adjusts its ride height to increase vehicle safety and to reduce fuel consumption. Changes to the vehicle level should be made while the vehicle is moving. The vehicle will then reach the set level as fast as possible. When you park the vehicle and the ambient temperature changes, the vehicle level may change visibly. When the temperature drops,

164_AKB; 7; 31, en-US d2ureepe,

the vehicle lowers. When the temperature rises, the vehicle raises. The vehicle automatically regulates its ride height based on the set vehicle height and the current speed: RAs your driving speed increases, the vehicle

is lowered by increments until it reaches highspeed level.

RVehicles with ADS: If you are driving with

the ADS setting COMF or AUTO, the vehicle is raised back to highway level as your driving speed decreases.

RVehicles with ADS: You can select the

highspeed level via the ADS setting SPORT. In ADS SPORT, the vehicle is lowered directly to highspeed level as your driving speed increases.

The vehicle begins adjusting to the set vehicle level as soon as the doors or tailgate are unlocked or opened or closed with the vehicle unlocked. In order to operate the vehicle level control switch (Y page 157), however, the engine must be running. G Warning! Make sure no one is near the wheel housing or under the vehicle when you lower the vehicle while it is standing still. Limbs could become wedged into or under the vehicle. For safety reasons, the vehicle can only be lowered with all doors and the tailgate closed. Lowering is interrupted if a door or the tailgate is opened and will continue after the door is closed again. G Warning! Please be aware that by raising the vehicle level, the center of gravity also rises. Therefore, always ensure that the vehicle level is as low as possible. With higher ride height the ESP® may activate earlier in certain situations. Adapt your speed and driving to possible changed driving behavior of the vehicle after

changing the vehicle level. The ESP® cannot prevent accidents, including those resulting from excessive speed. The ESP® cannot prevent the natural laws of physics from acting on the vehicle.

! Keep in mind that in rough or uneven terrain, adjusting the vehicle to a lower level may cause the vehicle underbody to come in contact with the ground and result in damage to the vehicle underbody. Always make sure the vehicle has sufficient ground clearance before adjusting it to a lower level.

! Before jacking up the vehicle with

equipment that lifts one or more of the wheels completely off of the ground, remove the SmartKey from the starter switch.

The rear automatic climate control allows separate climate settings for the rear compartment.

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.

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 169). 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 102). 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.
