Shiftlock button
First read and observe the introductory information and safety warn-
ings on page 139.
When the ignition is switched on, the gearbox mode and the currently selected gear are indicated in the display » Fig. 123.
The following modes can be selected with the selector lever » Fig. 123.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
The parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the engine
is at idling speed.
Before moving into mode R from mode P or N, depress the brake pedal and press
the locking button at the same time » Fig. 124.N
- Neutral
The power transmission to the drive wheels is interrupted in this mode.
D
- Mode for forwards travel (normal programme)
In mode D, the forward gears are automatically changed according to the engine
load, accelerator pedal actuation and driving speed.
S
- Mode for forwards travel (sports programme)
In mode S, the forward gears are shifted automatically up and down at higher en-
gine speeds than in mode D.
Before changing to mode S from mode D, press the locking button » Fig. 124
Releasing selector lever from mode P or N (selector lever lock) The selector lever is locked in modes P and N to prevent the forwards travel
mode from being selected accidentally and setting the vehicle in motion. The
warning light
illuminates in the instrument cluster » page 22.
The selector lever is released by depressing the brake pedal while the pressing
lock button at the same time » Fig. 124.
The selector lever is not locked when quickly moving via position N (e.g. from R to
D ). This, for example, helps to rock out a vehicle that is stuck, e.g. in a bank of
snow. The selector lever lock will engage if the lever is in position N for more than
approx. 2 seconds without the brake pedal being depressed.
The selector lever is locked only when the vehicle is stationary and at speeds up to 5 km/h.
Note
If you want to move the selector lever from mode P to mode D or vice versa, move
the selector lever quickly. This prevents modes R or N from being accidentally se-
lected.

also be deactivated by pulling the right-hand rocker switch +
towards the steer-
ing wheel for more than 1 second.
When accelerating, the gearbox automatically shifts up into the higher gear just before the maximum permissible engine speed is reached.
If a lower gear is selected, the gearbox does not shift down until there is no risk
of the engine overrevving.
Note
It may be beneficial, for example, when travelling downhill, to use manual shifting
of gears. Shifting to a lower gear reduces the load on the brakes and hence the
wear of the brakes » page 137.

Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)

Antilock Braking System (ABS)
151
Traction Control System (TCS)
151
Electronic Differential Lock (EDL)
151
Driver Steering Recommendation (DSR)
151
Hydraulic Brake Assist (HBA)

Hill Hold Control (HHC)
152WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then fail to function – risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety provided by the brake assist systems
must not tempt you to take safety risks – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS, as you will not know
the exact extent of the damage or the extent to which this is limiting the
braking efficiency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 193, Services, modifications, and
technical alterations .
■
If a fault occurs in the ABS system, the ESC, ASR and EDL will also not work. An
ABS fault is indicated by the warning light » page 19 .
Electronic Stability Control (ESC)Fig. 130
ESC system: TCS button
First read and observe the introductory information and safety warn-
ings on page 150.
The ESC system helps improve control of the vehicle in situations where it is be-
ing operated at its dynamic limits, such as a sudden change to the direction of
travel. Depending on the conditions of the road surface, the risk of skidding is re-
duced, thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched on.The direction which the driver wishes to take is determined based on the steering angle and the speed of the vehicle and is constantly compared with the actualbehaviour of the vehicle. In the event of deviations, such as the car beginning to
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the indicator light
flashes in the instru-
ment cluster.
The following systems are integrated into the Electronic Stability Control (ESC).

The ESC system cannot be deactivated. The
» Fig. 130 symbol button can only
be used to deactivate the ASR.
The warning light lights up in the instrument cluster when the ASR is deactiva-
ted.
150Driving

Antilock Braking System (ABS)First read and observe the introductory information and safety warn-
ings
on page 150.
ABS prevents the wheels locking when braking. Thus helping the driver to main-
tain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of the
brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pressure
on the brake pedal.
Traction Control System (TCS)
Fig. 131
TCS button
First read and observe the introductory information and safety warn- ings on page 150.
If the wheels are slipping, the TCS adapts the engine speed to the conditions of
the road surface. The TCS makes it much easier to start off, accelerate and climb
steep hills even if the conditions of the road surface are unfavourable.
The TCS function is activated automatically each time the ignition is switched on.
If your vehicle is fitted with the ESC system, the ASR is integrated into the ESC
system » page 150 .
During an intervention of the system, the TCS indicator light flashes in the in-
strument cluster.
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example.
› When driving with snow chains.
› When driving in deep snow or on a very loose surface.
› When “rocking a car free” when it has become stuck.
The ASR can be deactivated via the symbol button » Fig. 131
.
The warning light lights up in the instrument cluster when the ASR is deactiva-
ted.
Ensure the TCS is activated again afterwards.
Electronic Differential Lock (EDL)
First read and observe the introductory information and safety warn-
ings
on page 150.
If one of the wheels starts to spin, the EDL system brakes the spinning wheel and transfers the driving force to the other wheels. This ensures the stability of the
vehicle and a quick journey.
The EDL switches off automatically in order to avoid excessive heat generation in
the disc brake of the wheel 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.
Driver Steering Recommendation (DSR)
First read and observe the introductory information and safety warn-ings
on page 150.
In critical situations, the DSR provides the driver with a steering recommendation in order to stabilise the vehicle. The DSR is activated, for example, on the right
and left vehicle side when braking sharply on different road surfaces.
Hydraulic Brake Assist (HBA)
First read and observe the introductory information and safety warn-ings
on page 150.
The HBA increases the braking effect and helps to reduce the braking distance.
151Assist systems

The system only operates if the ignition is switched on.The displays, messages and system instructions are displayed in the MAXI DOTdisplay (in the display only below).
During the parking procedure the system only takes over the steering move-
ments, the pedals continue to be operated by the driver.
When the system is activated, the warning light lights up
» Fig. 133 on
page 154 - .
The traction control system (TCS) must always be switched on when parking.
Basis of the system function
› The measurement and evaluation of the size of parking spaces when driving.
› The determination of the correct position of the vehicle for parking.
› The calculation of the line on which the vehicle drives backwards into the park-
ing space or forwards from the parking space.
› the automatic turning of the front wheels when parking in, or manoeuvring out
of the parking space.WARNING■ The system does not exempt the driver from his/her responsibility for park-
ing in and manoeuvring out of the parking space.■
External sound sources can have a detrimental effect on parking in and ma-
noeuvring out of the parking space. Under adverse conditions, this may cause
objects or people to not be recognised by the system.
■
When parking in, and manoeuvring out of parking spaces, the system auto-
matically executes quick steering movements. While it is doing so, do not place your hands between the steering wheel – risk of injury!
■
When parking or departing from a parking space on loose or slippery surfa-
ces (gravel, snow, ice etc.), there may be deviations due to the conditions of
the calculated road surface. We therefore recommend not using the system in
such situations.
CAUTION
■ If other vehicles are parked behind or on the kerb, the system can guide your
vehicle beyond the kerb or onto it. Ensure that the wheels or the wheel rims of
your vehicle are not damaged and if necessary intervene in time.■
Under certain circumstances, the surfaces or structures of certain objects such
as wire mesh fences or powder snow cannot be detected by the system.
■ The evaluation of the parking space and the parking procedure depend on the
circumference of the wheels. The system only works correctly if the vehicle is fit- ted with the wheel size approved by the manufacturer.■
If wheels other than those approved by the manufacturer are mounted, the re-
sulting position of the vehicle in the parking space can differ slightly. This can be
avoided by readjusting the system at a specialist garage.
■
Under certain circumstances, the system may not function correctly, for exam-
ple, if the vehicle is fitted with snow chains or a temporary spare wheel.

Automatic brake assist
First read and observe the introductory information and safety warn-
ings
on page 153.
The system provides assistance to the driver with automatic brake assist. The au-
tomatic brake assist does not exempt the driver from his/her responsibility for
the accelerator, brake and clutch.
Automatic braking for preventing cancellations caused by excessive speeds
Automatic brake support can be used in order to stop the speed from exceeding
7 km/h, thereby preventing the subsequent cancellation of the parking procedure. The parking procedure can be resumed after automatic braking.
Automatic braking takes place only once per parking procedure.
Automatic braking for damage limitation
The system detects an imminent collision based on the driving speed and the dis-
tance from the obstacle, automatic brake support is initiated.
The system function is ended after this automatic brake assist for damage limita-
tion.WARNING■ Automatic brake assist only works as an element of the assist function. The
driver must always be ready to brake the vehicle him/herself.■
Automatic brake assist is ended after around 1.5 seconds. Depress the brak-
ing pedal so that the vehicle does not start moving by itself.
