Automatic gearbox*
112
Shiftlock button
The Shiftlock button in the handle of select or lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P.
Kickdown function
The kickdown function provides you with maximum acceleration
power.
Depressing the accelerator pedal beyond the pressure point casues the automatic
gearbox to shift down into a lower gear (in line with vehicle speed and engine
speed). The gearbox shifts up into the next higher gear when the engine has
reached its maximum revolutions.
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
faster style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freq uent changes in speed, exploiting the
top speed of the car or operating the kick down function, will cause the gearbox to
switch over to the sporty driving programme. Shifting up later into a higher gear
makes it possible to fully exploit the powe r reserves of the engine. The gearbox also
then shifts down at higher engine speeds than is the case for the economy-oriented
programmes.
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 into a
sporty driving programme by depressing the accelerator rapidly. The gearbox shifts
down into a lower gear matching the speed of the car and this allows you to accel-
erate rapidly (e.g. when overtaking) without having to depress the accelerator pedal
fully into the kickdown range. The original programme will be reactivated to match
your particular 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 gearbox frequently shifting up and down when negotiating
an uphill stretch. Depressing the brake pedal while driving downhill causes the
gearbox to shift down into the next lower gear. This makes it possible for you to
exploit the engine braking power withou t the need for shifting gears manually.

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 transporting a child on the front passenger
seat, please comply with the appropri ate 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 including 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 surfac e of the front passenger airbag in
the dash panel.
Side airbag
Description of side airbags
The side airbag together with the head airbag offers enhanced occu-
pant protection in the ev ent of a side collision.
The side airbags are housed in the upholstery of the backrests of the front seats and
are marked ⇒fig. 148 with the lettering “AIRBAG” on the middle part.
The side airbag system in combination with the three-point seat belts, offers addi-
tional protection for the upper area of the body (chest, stomach and pelvis) of the
occupants of the car in the event of a side collision of major severity ⇒ in
“Important safety information on the side airbag” on page 141.
Apart from their normal protective function, a further task of the seat belts is to
also hold the driver and front passenger in a correct seated position in the event of
a side collision so as to enable the side airbags to offer the maximum protection.
You should therefore always fasten the seat belts, not only because this is required
by law, but also for safety reasons and for your own protection ⇒page 130, “Why
seat belts?”.
Each time the side airbag is deployed, the head airbag* on the relevant side is auto-
matically deployed at the same time in order to provide the occupant with
enhanced protection ⇒page 142.

•when driving in deep snow or on a loose surface,
•when it is necessary to rock a ca r 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 205.
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 159, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 28 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. 164 . The TCS warning light ⇒page 28 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 to switch
the system off only in particular exceptional situations if you desire wheel slip.
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.
The EDL ⇒page 157, “Electronic Differential Lock (EDL)” is a part of the TCS. THE
EDL operates independently of the TCS (a lso when the TCS has been switched off
using the TCS button).
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 influence the function of the TCS ⇒page 205,
“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)
The electronic differential lock pr events an individual wheel from
slipping.
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 sl ippery 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 warning light comes on, this may also indicate a fault in the EDL.
Please have the car inspec ted 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 205,

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 increa sed to about 6 km/h 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 29.
•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 205,
“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
