Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the electronic parking brake is being tested on a brake test dynamometer or when the vehicle is being towed with one axle raised. Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty. Instrument cluster Introduction For a full view illustration of the instrument cluster, see “Instrument cluster” (Y page 29). G Warning! No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired. If you must continue to drive, do so with added caution. Contact an authorized Mercedes- Benz Center as soon as possible. The language setting for the multifunction display can be changed via COMAND (Y page 81). Activating the instrument cluster The instrument cluster is activated when you Ropen a door Rswitch on the ignition Rswitch on the exterior lamps Adjusting the instrument cluster illumination X To brighten illumination: Turn knob : clockwise. X To dim illumination: Turn knob : counterclockwise. i The instrument cluster illumination is dimmed or brightened automatically to suit ambient light conditions. The instrument cluster illumination will also be adjusted automatically when you switch on the vehicle’s exterior lamps. Coolant temperature gauge The coolant temperature gauge is located on the left side in the instrument cluster (Y page 29). G Warning! Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. 216_AKB; 3; 90, en-US d2ureepe, 2009-05-15T11:47:50+02:00 - Seite 301 Version: 2.11.8.1 Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down. During severe operating conditions, e.g. stop- and-go traffic, the coolant temperature may rise close to 248‡ (120†), i.e close to the red zone of the temperature gauge. ! Excessive coolant temperature triggers a warning in the multifunction display. The engine should not be operated with a coolant temperature above 248‡ (120†), i.e. in the red zone of the coolant temperature gauge. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty. Tachometer The red marking on the tachometer (Y page 29) denotes excessive engine speed. ! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty. To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking. Outside temperature indicator The outside temperature indicator is on the bottom left-hand side of the instrument cluster (Y page 29). G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Driving systems 301 Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. Fuel gauge The fuel gauge is on the left-hand side of the instrument cluster (Y page 29). Once the fuel level has fallen below the reserve mark, the yellow segment indicator for the fuel reserve comes on. Driving systems Introduction This section describes the following driving systems of your vehicle: RCruise control RDISTRONIC PLUS RHill-start assist system RHOLD function RAIRMATIC RActive Body Control (ABC) RAll-wheel drive (4MATIC) RParktronic system RPark Assist RAdvanced Parking Guidance RRear view camera RNight View Assist RBlind Spot Assist The driving safety systems ABS, Adaptive Brake, Adaptive Brake Lights, BAS, BAS PLUS, EBP, ESC and PRE-SAFE® Brake are described in the “Safety and security” section (Y page 56). 216_AKB; 3; 90, en-US d2ureepe, 302 Driving systems Cruise control The cruise control maintains the speed you set for your vehicle automatically. 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 set speed is shown by a triangle in the speedometer and the corresponding speedometer 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 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. 2009-05-15T11:47:50+02:00 - Seite 302 Version: 2.11.8.1 G Warning! When the cruise control is braking, the brake pedal is retracted (i.e. depressed automatically). The pedals’ range of motion must not be impeded by any obstacles: RDo not place any objects in the footwell. RMake sure that the floormats and carpets are securely in place. RDo not rest your foot underneath the brake pedal, as it could otherwise be trapped. You could otherwise cause an accident and injure yourself and/or others. : Setting current or higher speed ; Setting current or lower speed = Canceling the cruise control ?

The cruise control also switches off automatically when Rthe vehicle speed falls below 20 mph (30 km/h) Rthe ESC is in operation Rthe ESC is switched off via the control system Driving systems 303 Rthe ESC has switched off due to a malfunction Ryou shift the automatic transmission into neutral position N while driving The speedometer 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. 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. 2009-05-15T11:47:50+02:00 - Seite 304 Version: 2.11.8.1 X Briefly pull the cruise control lever in direction of arrow ?. If no speed is stored, the current speed is set and stored. X Remove your foot from the accelerator pedal. The last stored speed is deleted from memory when the engine is turned off. DISTRONIC PLUS Safety notes When activated, the DISTRONIC PLUS adaptive cruise control system increases the driving convenience afforded by the cruise control while traveling on expressways and other major roadways. RIf the DISTRONIC PLUS distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced so that you follow that vehicle at your preset following distance. RIf there is no vehicle directly ahead of you, the DISTRONIC PLUS will function in the same way as standard cruise control (Y page 302). G Warning! The DISTRONIC PLUS requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. 216_AKB; 3; 90, en-US d2ureepe, 304 Driving systems X Increasing: Briefly lift the cruise control lever up to the resistance point in direction of arrow :. X Decreasing: Briefly press the cruise control lever down to the resistance point in direction of arrow ;. X Release the cruise control lever.

Adjustment in 5 mph (Canada: 10 km/h) increments i The set speed value is increased or decreased in 5 mph (Canada: 10 km/h) increments each time you lift or press the cruise control lever up or down past the resistance point. X Increasing: Briefly lift the cruise control lever up past the resistance point in direction of arrow :. X Decreasing: Briefly press the cruise control lever down past the resistance point in direction of arrow ;. X Release the cruise control lever. The new speed is set and the vehicle will accelerate or decelerate. Keep in mind that it may take a brief moment until the vehicle has reached the set speed. Setting stored speed (Resume function) 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. 216_AKB; 3; 90, en-US d2ureepe, 2009-05-15T11:47:50+02:00 - Seite 305 Version: 2.11.8.1 G Warning! When the DISTRONIC PLUS is braking, the brake pedal is retracted (i.e. depressed automatically). The pedals’ range of motion must not be impeded by any obstacles: RDo not place any objects in the footwell. RMake sure that the floormats and carpets are securely in place. RDo not rest your foot underneath the brake pedal, as it could otherwise be trapped. You could otherwise cause an accident and injure yourself and/or others. G Warning! The DISTRONIC PLUS is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle’s speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver. The DISTRONIC PLUS cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by the DISTRONIC PLUS. This could result in wrong or missing distance warnings. G Warning! The DISTRONIC PLUS adaptive cruise control is not a substitute for active driving involvement. It does not react to pedestrians or on stationary objects, nor does it recognize or predict the curvature and lane layout or the movement of preceding vehicles. The DISTRONIC PLUS can only apply a maximum of 40% of the vehicle’s braking power. The DISTRONIC PLUS may not detect narrow vehicles possibly driving in front of you, such Driving systems 305 as motorcycles and vehicles driving in an offset formation. It is the driver’s responsibility at all times to be attentive to the road, weather and traffic conditions. Additionally, the driver must provide the steering, braking and other driving inputs necessary to remain in control of the vehicle. High-frequency sources such as toll stations, speed measuring systems etc. can cause the DISTRONIC PLUS system to temporarily cease functioning. G Warning! The DISTRONIC PLUS cannot take road and traffic conditions into account. Only use the DISTRONIC PLUS if the road, weather and traffic conditions make it advisable to travel at a constant speed. G Warning! Use of the DISTRONIC PLUS can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. The DISTRONIC PLUS does not function in adverse sight and distance conditions. Do not use the DISTRONIC PLUS during conditions of fog, heavy rain, snow or sleet. G Warning! The DISTRONIC PLUS cannot take weather conditions into account. Switch off the DISTRONIC PLUS or do not switch it on if: Rroads are slippery or covered with snow or ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid. Rthe DISTRONIC PLUS system sensor covers are dirty or visibility is diminished due to snow, rain or fog, for example. The distance control system functionality could be impaired. Always pay attention to surrounding traffic conditions even while the DISTRONIC PLUS is 216_AKB; 3; 90, en-US d2ureepe, 306 Driving systems switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late. This could cause an accident in which you and/or others could be injured. G Warning! 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! Close attention to road and traffic conditions is imperative at all times, regardless of whether or not the DISTRONIC PLUS is activated. Use of the DISTRONIC PLUS can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed. The DISTRONIC PLUS will not react to stationary objects in the roadway (e.g. a stopped vehicle in a traffic jam or a disabled vehicle). The DISTRONIC PLUS will also not respond to oncoming vehicles. Switch off the DISTRONIC PLUS: Rwhen changing from the left to the right lane if vehicles are moving more slowly in the left lane Rwhen entering a turn lane or highway off ramp Rin complex driving situations, such as in highway construction zones In these situations, the DISTRONIC PLUS will continue to maintain the set speed unless deactivated. The DISTRONIC PLUS is designed and intended only to maintain a set speed and keep a set distance from moving objects in front of it. The DISTRONIC PLUS functions in a speed range of 0 to 120 mph (Canada: 0 to 200 km/h) if a preceding vehicle is detected. If no preceding vehicle is detected the DISTRONIC PLUS functions in a 2009-05-15T11:47:50+02:00 - Seite 306 Version: 2.11.8.1 speed range of 20 to 120 mph (Canada: 30 to 200 km/h). Always obey applicable speed limits. Do not use the DISTRONIC PLUS if you are driving on a road with steep uphill or downhill slopes. When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 216). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada. When you switch off the radar sensor system, the following functions are deactivated: RDISTRONIC PLUS RBAS PLUS (Y page 57) RPRE-SAFE® Brake (Y page 62) RPark Assist (Y page 324) RAdvanced Parking Guidance (Y page 327) RBlind Spot Assist (Y page 335) i Due to its radar-emitting nature DISTRONIC PLUS may have an appearance similar to a radar detector to law enforcement officials. You may want to refer to this section of your Operator’s Manual when asked. i USA only: This device has been approved by the FCC as a “Vehicular Radar System”.

DISTRONIC PLUS displays in multifunction display : Speed of the vehicle ahead ; Marker = Distance warning lamp If the DISTRONIC PLUS is activated, marker ; indicates the set speed. The vehicle speed displayed on the speedometer can briefly vary from the speed setting on the DISTRONIC PLUS system. If the DISTRONIC PLUS detects a vehicle directly ahead, the ring on the speedometer dial comes on between the speed of the vehicle ahead : and the set speed. Driving systems 307 If the DISTRONIC PLUS 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 brake to avoid a collision. Under no circumstances should the driver await the intermittent warning sound before braking. See the following warning note. The intermittent warning sound ceases and the distance warning lamp · goes out when the necessary distance to the vehicle ahead is again established. G Warning! An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the DISTRONIC PLUS system calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that the DISTRONIC PLUS 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 PLUS brakes your vehicle with a maximum deceleration of 13 ft/s2 (4 m/s2). This corresponds to approximately 40% of the maximum deceleration of your vehicle. 216_AKB; 3; 90, en-US d2ureepe, 308 Driving systems You must also apply the brakes yourself to avoid a collision. The DISTRONIC PLUS brakes the vehicle in an effort to restore the preset distance or to maintain the set speed. The brake pedal is automatically applied as this happens which results in the brake pedal moving Keep driver’s foot area 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 DISTRONIC PLUS system. Do not place your foot under the brake pedal – your foot could become caught. G Warning! If you do not receive visual or acoustic warning signals during a critical traffic situation, DISTRONIC PLUS has either not recognized the collision risk, has been deactivated or is malfunctioning. Remember, whether or not DISTRONIC PLUS is operating, it is ultimately always the drivers responsibility to apply the brakes in order to control the vehicle and avoid a collision. Displaying the distance graphic In the DriveAssist menu under Distance Display you see the current settings for DISTRONIC PLUS. The Information shown in the multifunction display depends on whether DISTRONIC PLUS is activated or deactivated. For activating or deactivating the DISTRONIC PLUS system, see “Activating DISTRONIC PLUS” (Y page 309) or “Deactivating DISTRONIC PLUS” (Y page 312).

Never get out of the vehicle while the DISTRONIC PLUS is switched on! The DISTRONIC PLUS must never be operated or switched off by passengers or from outside the vehicle. The DISTRONIC PLUS is not a substitute for the electronic parking brake. It must not be used to secure the vehicle when parking. When you get out of the vehicle or switch off the engine, deactivate the DISTRONIC PLUS and secure the vehicle from rolling away by engaging the electronic parking brake. When the DISTRONIC PLUS detects that the preceding vehicle is stopping, the vehicle brakes until it also stops. Once the vehicle is at a standstill, it remains stationary, without depressing the brake pedal. After a short while, the vehicle is secured in place by the electronic parking brake so that the operating brake can be relieved of load. Depending on the following distance set using the distance setting switch on the DISTRONIC PLUS lever (Y page 313), the vehicle will stop adequate away from the preceding vehicle.

(Y page 309) for driving off and the front passenger or a rear passenger door is open The marker for the set speed on the speedometer dial go out, an acoustic signal sounds, and the message DISTRONIC PLUS Off appears in the multifunction display for approximately 5 seconds. G Warning! The DISTRONIC PLUS 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 unless the DISTRONIC PLUS detects a vehicle directly ahead of you. 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 PLUS. After a brief acceleration (e.g. for passing), the DISTRONIC PLUS will resume the last set speed. Setting the following distance in DISTRONIC PLUS You can set the specified following distance for the DISTRONIC PLUS by varying the time setting between 1.0 and 2.0 seconds. Using this time setting and the current speed of your vehicle, the DISTRONIC PLUS 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 distance setting switch : in direction of arrow ;. Increasing the distance setting tells the DISTRONIC PLUS to maintain a greater following distance to the preceding vehicle. X Decreasing distance: Turn distance setting switch : in direction of arrow =. Decreasing the distance setting tells the DISTRONIC PLUS to maintain a shorter following distance to the preceding vehicle. Driving with DISTRONIC PLUS 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 PLUS system. G Warning! The DISTRONIC PLUS 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 PLUS could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed. 216_AKB; 3; 90, en-US d2ureepe, 314 Driving systems The DISTRONIC PLUS regulates only the distance between your vehicle and those directly ahead of it. It may 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 PLUS should not be used in snowy or icy road conditions. The most likely cause for a malfunctioning system is a dirty sensor (located in the hood grille and in the bumper), especially at times of snow and ice or heavy rain. In such a case, the DISTRONIC PLUS will switch off, and the message DISTRONIC PLUS Currently Unavailable See Oper. Manual appears in the multifunction display. For cleaning and care of the sensors, see (Y page 406). i If the message DISTRONIC PLUS Currently Unavailable See Oper. Manual disappears during driving and the last speed stored flashes for approximately 5 seconds, the dirt (e.g. slush) has dissolved; the DISTRONIC PLUS is available again. Another cause might be that the radar sensors have been manually switched off in the instrument cluster control system. Please verify that the radar sensors are switched on (Y page 216). 2009-05-15T11:47:50+02:00 - Seite 314 Version: 2.11.8.1 Turns and bends In turns or bends, the DISTRONIC PLUS may not detect a preceding vehicle, 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 PLUS. There will be insufficient distance to the preceding vehicle. Lane changing 216_AKB; 3; 90, en-US d2ureepe, 2009-05-15T11:47:50+02:00 - Seite 315 Version: 2.11.8.1 Driving systems 315 The DISTRONIC PLUS has not yet detected the vehicle changing lanes. There will be insufficient distance to the lane-changing vehicle. Narrow vehicles Cross-traffic Because of their narrow profile, the vehicles traveling near the outer edges of the lane have not yet been detected by the DISTRONIC PLUS. There will be insufficient distance to the preceding vehicles. Obstacles and stationary vehicles The DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the vehicle detected in front of you changes lanes to bypass an obstacle or stationary vehicle in front of it, the DISTRONIC PLUS will not brake for the obstacle or stationary vehicle. The DISTRONIC PLUS may inadvertently detect crossing vehicles. If you switch on the DISTRONIC PLUS, for example, at a traffic light with cross traffic, the vehicle may suddenly start to drive off. Hill-start assist system 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.
