Automatic gearbox100
gearbox does not shift up into the highest gear until the engine has reached its maximum revolutions for this gear range.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and down through the gears is performed auto matically on the basis of pre-defined driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most economical driving programme. Shifting up into a higher gear as soon as possible and shifting down as late as possible will have a favourable effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal combined with sharp acceleration and frequent changes in speed, exploiting the top speed of the car or depressing the a ccelerator pedal (kickdown function), will cause the gearbox to switch over to this style of driving and shift down earlier with frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving is a continuous process. Irrespective of this it is, however, possible to switch or shift down into a dynamic shift programme by depressing the accelerator rapidly. The gearbox shifts down into a lower gear matc hing the speed of the car and this allows you to accelerate rapidly (e.g. when ov ertaking) without having to depress the accelerator pedal fully into the kickdown range. The original programme will be reactivated to match your part icular style of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill sections. This avoids the ge arbox frequently shifting up and down when negotiating an uphill stretch. When driving downhill, it is possible to shift down into the Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
Switching over to manual shifting
– Push the selector lever to the right out of position D. As soon as the
gearbox has switched over, 6 5 4 3 2 1 appears in the display, with the
gear engaged being highlighted.

Communication104
Universal telephone preinstallation with voice
control*
The voice control is activated according to equipment installed on the vehicle by pressing the button PTT (push to talk)  on the adapter ⇒fig. 112 or the button  on the multi-functional module* ⇒page 103.
A phone phonebook is part of the mobile phone preinstallation with voice control. In the phone phonebook there are 1500 free memory locations available. This phone phonebook can be used in line with the mobile telephone.
For vehicles fitted with multi-functional module*, the operation is performed via the function buttons on the module ⇒page 103.
Furthermore the volume can be changed indi vidually at any time with the button for setting the radio or on vehicles fitted with multi-functional module* with func- tion buttons on the steering wheel.
If the system answers with the voice response “ Telephone is not ready”, please check the operating state of the telephone as follows:
•Is the telephone switched on?
•Is the PIN code entered?
Dialogue
The period, in which the telephone system is ready to receive voice commands and carry out the voice commands, is called DIALOGUE. The system gives audible feed-
back and guides you if necessary through the relevant functions. You can start or end the dialogue at any time by pressi ng the PTT button. You can also end the dialogue with the voice command CANCEL.
The dialogue is always automatically ended after carrying out an operation, e.g. after erasing the name from the phonebook.
The dialogue of the incoming call is i mmediately interrupted and you can accept the call by pressing the button .
If a voice command is not detected, the system answers with “ Sorry?” and a new entry can be performed. After the 3rd error the answer “ Cancel” is given and the dialogue is ended.
Optimum understanding of the voice commands depends on the following factors:
•Speak with a normal tone of voice wi thout intonation and excessive voice pauses.
•Avoid insufficient articulation.
•Close the doors, windows and sliding roof, in order to reduce or stop disturbing exterior noise.
•It is recommended to speak louder at higher speeds, so that the tone of your voice is louder than the increased surrounding noise.
•During the dialogue avoid additional nois e in the vehicle, e.g. simultaneously talking occupants.
•Do not speak, if the system makes an announcement.
•The microphone for voice control is directed to the driver and front passenger. Therefore the driver and the front passenger can operate the equipment.
WARNING
Pay attention primarily to the traffic si tuation! As the driver you are fully responsible for the traffic safety. Use the telephone system only to such an extent, so that you are in full control of your vehicle at any time.

Airbag system131
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
In certain accident situations both the front airbags as well as the head and side airbags may be deployed together.
If the airbags are deployed, the airbags are filled with a propellant gas and inflated in front of the driver and front passenger ⇒page 130, fig. 127. The airbags inflate in fractions of a second and at a high speed in order to be able to offer that addi- tional protection in the event of an acci dent. The forward movement of the driver and of the front passenger is cushioned when they make contact with the fully inflated airbag and the risk of injury to head and chest is thus reduced.
The specially developed airbag allows the gas to flow out of the inflated airbag in a controlled manner (depending on the load of the particular car occupant) in order to cushion head and chest areas. The airbag then deflates subsequently to such an extent, after an accident, to again provide a clear view forward.
A grey white, non harmful gas is released when airbag is inflated. This is perfectly normal and is not an indication of a fire in the vehicle.
The airbag develops enormous forces when triggered, which can lead to injuries if the sitting position or seated position is not correct ⇒ in “Important safety information regarding the front airbag system” on page 131.
Important safety information regarding the front airbag system
Correct use of the airbag system considerably reduces the risk of
injury!
WARNING
•Never transport children on the front seat of a vehicle without using a proper restraint system. If airbags are deployed in the event of an accident, the child might suffer severe or even fatal injuries!
•For the driver and front passenger it is important to maintain a distance of at least 25 cm from the steering wheel or dash panel ⇒fig. 128. Not main- taining this minimum distance will mean that the airbag system will not be able to properly protect you - hazard! The front seats and the head restraints must always also be correctly adjusted to match the body size of the occu- pant.
•It is essential to always switch off ⇒page 135, “Deactivating an airbag” the front passenger airbag when attaching a child safety seat on the front passenger seat where the child is seated with its back facing in direction of travel (in some countries al so when the child is facing the direction of travel). If this is not done, there is a risk of the child suffering severe or even fatal injuries if the front passenger airbag is deployed. In certain countries national legal provisions also requir e that the side or head passenger airbags be deactivated. When transpor ting a child on the front passenger seat, please comply with the appropriate national regulations regarding the use of child safety seats.
•There must not by any further persons, animals or objects positioned between the front seated occupants and the deployment area of the airbag.
•The steering wheel and the surface of the airbag module in the dash panel on the passenger side must not be stuck onto, covered or modified in any other way. These parts should only be cleaned with a dry cloth or a cloth moistened with water. No objects such as cup holders, mobile phone mounts, etc. may be attached to the covers of the airbag modules or be located within the immediate area.
•No modifications of any kind may be made to parts of the airbag system. Any work on the airbag system includ ing installing and removing system components because of other repair work (e.g. removing the steering wheel) must only be carried out by a specialist garage.
•Never carry out changes on the front bumper or on the body.
•Never place any objects on the dash panel on the front passenger side.

•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the road surface and the traffic situation. This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-free operation of the ESP. Differing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can influence the function of the ESP ⇒page 193, “Accessories, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.
General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e engine is started and then conducts a self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels ar e spinning, the force transmitted to the road surface is automatically adapted by reducing the engi ne speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 149, “Antilock brake system (ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 26 lights up in the instrument cluster when there is a fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the button ⇒ fig. 146. The TCS warning light ⇒page 26 lights up in the instrument cluster when the TCS is switched off.

The TCS should normally always be switched on. It may be good practice in certain exceptional cases, such as when you wish to have wheel slip, to switch off the system.
Examples:
•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem- free operation of the TCS. Differing rollin g circumferences of the tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can in fluence the function of the TCS ⇒page 193, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock pr events an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio ns of the road surface are unfavourable.
Operating principle
The EDL is activated automatically, that is without any action on the part of the driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only one drive wheel begin spinning on a slippery surface there will be an appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proce ss is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unus ually severe stresses exist in order to avoid excessive heat generation in the disc brake on the wheel which is being braked. The vehicle can continue to be driven and has the same characteristics as a vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slip- pery road surfaces, such as ice and sn ow. The driven wheels might still spin despite the EDL and affect the stability of the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition of road surface and to the traffic situation even when your vehicle is fitted with EDL. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in the EDL. Please have the car inspected as soon as possible by a specialist garage.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can in fluence the function of the EDL ⇒page 193, “Accessories, changes and replacement of parts”.

WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running. Greater physical effort for braking is required when engine is switched off. Because if you do not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)*
ABS prevents the wheels locking when braking.
General
The ABS contributes significan tly to enhancing the active safety of your vehicle. Compared to a car not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu ll brake application on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the br aking distance will be shorter under all circumstances as a result of the ABS. Th e braking distance for example on gravel and fresh snow, when you should anyway be driving slowly and cautiously, will be longer.
Operating principle
As soon as the vehicle speed has increase d to about 20 km/hour an automatic test procedure is conducted during which you wi ll be able to hear a pumping noise for about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend ing to lock. This control cycle is notice- able from a pulsating movement of the brake pedal which is accompanied by noises. This is consciously intended to pr ovide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima lly control the brake application in this braking range. Never interrupt the application of the brakes!
WARNING
•The ABS can also not overcome the physic al limits of your vehicle. Please do not forget this, particularly when driv ing on icy or wet road surfaces. If the ABS is operating within the control ra nge, adapt your speed immediately to the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!
•The normal braking system is still fully functional if there is an ABS fault. Visit a specialist garage as quickly as po ssible and adjust your style of driving to take account of the ABS fault in the meantime since you will not know how great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system ⇒page 27.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can in fluence the function of the ABS ⇒page 193, “Accessories, changes and replacement of parts”.
Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but do not depress the brake pedal with suff icient pressure. Consequently, it is not possible for the car to achieve its maxi mum deceleration and the car covers a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure ex ists than during a normal brake applica- tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the car. You must apply the brake

Intelligent Technology150
pedal firmly and hold it in this position in order to achieve the shortest possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure required in the brake system. It fully exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available. Further information on the ESP ⇒page 145.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic situation.
•The increased safety offered by the Brake Assist must not tempt you to take a greater safety risk than otherwise.
Electrohydraulic power steering
The power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power st eering system if the steering is turned to full lock when the vehicle is stationary. Turning the steering to full lock in such a situation will be acco mpanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The only difference is that greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due to the low vehicle network voltage if the battery has gone flat and the engine must started with the help off jump leads. This conditio n will be indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific range when engine is running. It also operates again, if the engine can be started with its own battery.
Caution
Do not leave the steering at full lock fo r more than 15 seconds when the engine is running - risk of damagi ng the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if there is a leak or fault in the system.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference of the individual wheels. If the infla- tion pressure and therefore the rolling circumference of a wheel has changed signif- icantly, the warning light  lights up in the dash panel ⇒page 26. The tyre inflation pressure-control system function s late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,
