The synchronization must be repeated if the panorama sliding/pop-up roof cannot be fully opened (Express-open).
Solar panel*
A solar panel is available in combination with the panorama sliding/pop-up roof. The solar cells convert natural light into electrical energy. When the engine is switched off, the energy generated auto- matically switches on the ventilation fan. The constant air flow creates a cooler tem- perature for cars parked in the sunlight. The air flow depends on the intensity of the solar radiation. The ventilation starts two minutes after switching off the engine.

왔 Driving systems The following driving systems are ex- plained on the following pages: 앫 Cruise control and Distronic*, with
which the vehicle can maintain a preset speed
앫 Airmatic* adjusts the vehicle suspen- sion characteristics automatically and controls the vehicle level
앫 Parktronic system*, which assists the
driver during parking maneuvers
The BAS, ABS, ESP and SBC are described in the “Safety and Security” section (컄 page 74).
Cruise control
The cruise control automatically maintains the speed you set for your vehicle. Use of cruise control is recommended for driving at a constant speed for extended periods of time. You can set any speed over 20 mph (30 km/h). The cruise control function is operated by means of the cruise control lever. The cruise control lever is the uppermost lever found on the left-hand side of the steering column (컄 page 20).
Controls in detail Driving systems
Warning!
Cruise control is a convenience system de- signed to assist the driver during vehicle op- eration. The driver is and must always remain responsible for the vehicle speed and for safe brake operation.
Only use cruise control if the road, traffic and weather conditions make it advisable to travel at a steady speed. 앫 The use of cruise control can be danger- ous on winding roads or in heavy traffic because conditions do not allow safe driving at a steady speed.
앫 The use of cruise control can be danger- ous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.
앫 Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper- ated if the driver is fully aware of the previ- ously set speed and wishes to resume this particular preset speed.
211
! Moving gear selector lever to position N while driving also cancels cruise control. However, the gear se- lector lever should not be moved to position N while driving except to coast when the vehicle is in danger of skid- ding (e.g. on icy roads).
The last stored speed is canceled when you turn off the engine.
On uphill or downhill grades, cruise control may not be able to maintain the set speed. Once the grade eases, the set speed will be resumed.
Canceling cruise control There are several ways to cancel cruise control: 왘 Step on the brake pedal. or 왘 Briefly push the cruise control lever to
position 3. Cruise control will be canceled. The last speed set will be stored for later use.

Distronic*
When activated, the Distronic adaptive cruise control system increases driving convenience afforded by the cruise control during travel on expressways and other major roads. 앫 If the Distronic distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced so that you follow that vehicle at a preset distance.
앫 If there is no vehicle directly ahead of you, Distronic will function in the same way as cruise control (컄 page 218).
Warning!
Distronic adaptive cruise control is no sub- stitute for active driving involvement. It does not react to stationary objects, nor recog- nize or predict the curvature and lane layout or the movement of vehicles ahead. Distronic can only apply a maximum of 20% of the vehicle’s braking power.
214
It is the driver’s responsibility at all times to be attentive to traffic and road conditions and to provide the steering, braking and oth- er driving inputs necessary to retain control of the vehicle.
Warning!
Distronic is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. However, it is not intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle speed and the distance to the ve- hicle ahead, including most importantly brake operation to assure safe stopping dis- tance, always rests with the driver.
Distronic cannot take street and traffic con- ditions into account.
Warning!
Distronic requires familiarity with its opera- tional characteristics. We strongly recom- mend that you review the following information carefully before operating the system.
For operation in the USA only: This de- vice complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 앫 this device may not cause harmful
interference, and
앫 this device must accept any inter- ference received, including interfer- ence that may cause undesired operation.
Any unauthorized modification to this device could void the user’s authority to operate the equipment.
Warning!
Warning!
Distronic cannot take street and traffic con- ditions into account. Only use Distronic if the road, weather and traffic conditions make it advisable to travel at a steady speed.
Warning!
Use of Distronic can be dangerous on slip- pery roads. Rapid changes in tire traction can result in wheel spin and loss of control.
Distronic does not act upon adverse sight distance conditions. Do not use Distronic during conditions of fog and heavy rain, snow or sleet.
Close attention to road and traffic condi- tions is imperative at all times, regardless of whether or not Distronic is activated.
Use of Distronic can be dangerous on wind- ing roads or in heavy traffic because condi- tions do not allow safe driving at a steady speed.
Distronic will not react to stationary objects in the roadway (e.g. a stopped vehicle in a traffic jam or a disabled vehicle). Distronic will also not respond to oncoming vehicles.
Switch off Distronic: 앫 when changing from the left to the right lane if vehicles are moving more slowly in the left lane
앫 when entering a turn lane or highway off
ramp
앫 in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to maintain the set speed unless deactivated.
Controls in detail Driving systems
Distronic is designed and intended only to maintain a set speed and keep a set dis- tance from moving objects in front of it.
Warning!
The “Resume” function should only be oper- ated if the driver is fully aware of the previ- ously set speed and wishes to resume this particular preset speed.

a collision.
216
Warning!
Warning!
An intermittent warning sounds and the DTR warning lamp in the instrument cluster is illuminated if the Distronic system calcu- lates that the distance to the vehicle ahead and your vehicle’s current speed indicate that Distronic will not be capable of slowing the vehicle sufficiently to maintain the pre- set following distance, which creates a dan- ger of a collision.
Immediately brake the vehicle to increase the distance to the vehicle in front of you. The warning sound is intended as a final cau- tion that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the op- eration of the warning signal to intercede with your own braking, as that will result in potentially dangerous emergency braking which will not always result in an impact be- ing avoided.
Tailgating increases the risk of an accident.
Distronic brakes your vehicle with a maxi- mum deceleration of 6.5 ft/s2 (2 m/s2). This corresponds to about 20% of the maxi- mum deceleration ability of your vehicle.
Distronic brakes the vehicle in an effort to restore the preset distance or to maintain the 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, in- cluding the area under the brake pedal. Ob- jects stored in this area may impair pedal movement which could interfere with the braking ability of the Distronic system.
Do not place your foot under the brake pedal – your foot could become caught.

Warning!
Distronic switches off and releases the brakes when the vehicle decelerates below the minimum speed of approximately 25 mph (40 km/h) by operation of the sys- tem. At that time the driver must apply the brakes in order to reduce vehicle speed fur- ther or bring it to a stop.
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 recom- mendations for safe following distance.

앫 An intermittent warning sounds. If these warnings are issued, you must brake manually to maintain a safe distance and avoid a collision with the vehicle ahead. When pressing the brake pedal, the warn- ing sound stops. The warning sound also stops when the distance to the vehicle
ahead is sufficient again without applying the brake pedal. In this case the distance warning lamp also extinguishes.
Warning!
If the DTR warning lamp l in the instru- ment cluster comes on while driving and/or an intermittent warning sounds, immediate attention on the part of the driver is re- quired.
As required by the traffic situation, apply the brakes and navigate around a possible ob- stacle. However, do not drive by relying on the distance warning function, as this will re- sult in an emergency braking application. Especially depending on road surface condi- tions and driver reaction, this will not always enable you to avoid a collision.

Driving with Distronic This section describes a number of driving situations where special precaution is re- quired on the part of the driver. Be pre- pared to brake in such situations. This will deactivate the Distronic system.
Warning!
Distronic works to maintain the speed se- lected by the driver unless a moving obsta- cle proceeding directly ahead of it in the same travel direction is detected (e.g. fol- lowing another vehicle ahead of you at a dis- tance set by Distronic). This means that: 앫 Your vehicle can pass another vehicle
after you change lanes
앫 While in a sharp turn or if the vehicle in front is in a sharp turn, Distronic could lose sight of a vehicle traveling in front of it, then your vehicle could accelerate to the previously selected speed.
Controls in detail Driving systems
Distronic regulates only the distance be- tween your vehicle and those directly ahead of it, but does not register stationary objects in the road, e.g.: 앫 A stopped vehicle in a traffic jam 앫 A disabled vehicle 앫 An oncoming vehicle The driver must always be on the alert, ob- serve all traffic and intercede as required by steering or braking the vehicle.
Warning!
Distronic should not be used in snowy or icy road conditions.
223
Controls in detail Driving systems
The most likely cause for a malfunctioning system is a dirty sensor (located behind the hood grille), especially at times of snow and ice or heavy rain. In such a case, Distronic will switch off, and the message Currently unavailable see oper. manual appears in the multifunction display. For cleaning and care of the Distronic sen- sor, see “Cleaning the Distronic system sensor” (컄 page 305).
Turns and bends
If the message “Distronic - clean sen- sor!” See oper. manual disappears dur- ing driving and the last speed stored flashes for approximately five seconds, the dirt (e.g. slush) has dissolved; Distronic works again.
In turns or bends, 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.

Make sure that no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.
The Parktronic system is an electronic aid designed to assist the driver during park- ing maneuvers. It visually and audibly indi- cates the relative distance between the vehicle and an obstacle. The Parktronic system is automatically ac- tivated when you switch on the ignition and release the parking brake. The Parktronic system deactivates at speeds over 11 mph (18 km/h). At lower speeds the Parktronic system turns on again.
Parktronic system* (Parking assist)
Warning!
The Parktronic system is a supplemental system. It is not intended to, nor does it re- place, the need for extreme care. The re- sponsibility during parking and other critical maneuvers always rests with the driver.
Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or road curbs). Such objects may not be detected by the system and can damage the vehicle.
The operational function of the Parktronic system can be affected by dirty sensors, es- pecially at times of snow and ice. See “Cleaning the Parktronic system sensors” (컄 page 305). Interference caused by other ultrasonic sig- nals (e.g. working jackhammers or the air brakes of trucks) can cause the system to send erratic indications, and should be tak- en into consideration.

The handling characteristics of a fully load- ed vehicle depend greatly on the load dis- tribution. It is therefore recommended to load the vehicle according to the illustra- tions shown, with the heaviest items being placed towards the front of the vehicle. Always place items being carried against front or rear seat backrests, and fasten them as securely as possible. The heaviest portion of the cargo should al- ways be kept as low as possible since it in- fluences the handling characteristics of the vehicle.
Warning!
Always fasten items being carried as secure- ly as possible.
In an accident, during hard braking or sud- den maneuvers, loose items will be thrown around inside the vehicle and can cause in- jury to vehicle occupants unless the items are securely fastened in the vehicle.
To help avoid personal injury during a colli- sion or sudden maneuver, exercise care when transporting cargo. Put luggage or car- go in the trunk if possible. Do not pile lug- gage or cargo higher than the seat backs. Do not place anything on the rear-window shelf.

Tele Aid*
The initial activation of the Tele Aid sys- tem may only be performed by com- pleting the subscriber agreement and placing an acquaintance call using the SOS button. Failure to complete either of these steps will result in a system that is not activated. If the system is not activated, the indicator lamp in the SOS button stays on after turning the SmartKey in starter switch to position 2, or pressing the KEYLESS-GO* start/stop button twice to position 2. The message Tele Aid – not activated will be shown in the multifunction display for approximately 10 seconds. If you have any questions regarding ac- tivation, please call the Response Cen- ter at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada).
The Tele Aid system (Telematic Alarm Identification on De- mand) The Tele Aid system consists of three types of response: 앫 automatic and manual emergency 앫 roadside Assistance and 앫 information The Tele Aid system is operational provid- ing that the vehicle’s battery is charged, properly connected, not damaged and cel- lular and GPS coverage is available. The speaker volume of a Tele Aid call can be adjusted when using the volume control on the multifunction steering wheel. To raise, press button æ and to lower, press button ç. 왘 To activate, press the SOS button, the
Roadside Assistance button • or the Information button ¡, depend- ing on the type of response required.
i The SOS button is located above the in- terior rear view mirror. The Roadside Assistance button • and the Information button ¡ are located below the center armrest cov- er.
Shortly after the completion of your ac- quaintance call, you will receive a user ID and password via first call mail. By visiting www.mbusa.com and selecting “Tele Aid” (USA only), you will have access to account information, remote door unlock and more.
The Tele Aid system utilizes the cellular network for communication and the GPS (Global Positioning System) satel- lites for vehicle location. If either of these signals are unavailable, the Tele Aid system may not function and if this occurs, assistance must be sum- moned by other means.
System self-check Initially, after turning the ignition on, mal- functions are detected and indicated (the indicator lamps in the SOS button, the Roadside Assistance button • and the Information button ¡ stay on longer than ten seconds or do not come on). The message TELE AID – VISIT WORKSHOP! ap- pears for approximately 10 seconds in the multifunction display.
