Information on braking
124
Handbrake
125WARNING■ Greater physical effort is required for braking when the engine is switched
off – risk of accident!■
During the braking procedure on a vehicle with manual transmission, when
the vehicle is in gear and at low revs, press the clutch pedal. Otherwise, the
function of the brake booster may be impaired – risk of accident!
■
Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle could then start to move – risk of accident!
WARNINGIn the event of damage occurring to the standard fitted front spoiler or the
retrofitting of another front spoiler, wheel hubs etc. » page 184, Service work,
adjustments and technical alterations , It must be ensured that the air supply
to the front brakes is not impaired. The front brakes may overheat which can
have a negative impact on the functioning of the braking system – risk of acci- dent!
CAUTION
■ Observe the recommendations on the new brake pads » page 130.■Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
Information on braking
First read and observe the introductory information and safety warn-
ings
on page 124.
If the brakes are applied in full and the control unit for the braking system consid-
ers the situation to be dangerous for the following traffic, the brake light flashes
automatically.
After the speed was reduced below around 10 km/h or the vehicle was stopped,
the brake light stops flashing and the hazard warning light system switches on.
The hazard warning light system is switched off automatically after accelerating
or driving off again.
Before driving a long distance at a steep incline, reduce speed and shift into the
next lowest gear. As a result, the braking effect of the engine will be used, reduc- ing the load on the brakes. Any additional braking should be completed intermit-tently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving style.
The brake pads wear more quickly if a lot of journeys are completed in towns and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned and dried by applying the brakes several times.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropriate-ly, as you will not know the exact extent of the damage.

138WARNING■ 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 184, Service work, adjustments
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. 116
ESC system: TCS button
First read and observe the introductory information and safety warn-
ings on page 136.
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. The risk of skidding is reduced and your car thus offers greater driving sta-
bility depending on the conditions of the road surface.
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 actual
behaviour 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).

be used to deactivate the ASR.
The warning light lights up in the instrument cluster when the TCR is deactiva-
ted.
136Driving
Antilock brake system (ABS)First read and observe the introductory information and safety warn-
ings
on page 136.
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. 117
TCS button
First read and observe the introductory information and safety warn- ings on page 136.
If the wheels are slipping, the TCS adapts the engine speed to the conditions ofthe 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 136 .
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 it is necessary to “rock” a car free when it has become stuck.
The ASR can be deactivated via the
» Fig. 117 symbol button.
The warning light lights up in the instrument cluster when the TCR 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 136.
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 itself off automatically, in order to avoid excessive heat genera-
tion 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 136.
In critical situations, the DSR provides the driver with a steering recommendationin 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 136.
The HBA increases the braking effect and helps to reduce the braking distance.

Switching on
The system is activated automatically by engaging the reverse gear.
Switching off
The system is turned off when any of the following is present.
› The reverse gear is disengaged.
› The symbol key
is pressed.
› The speed of 15 km/h is exceeded.
› The ignition is switched off.
For cars without PDC (OPS), the system is turned off about 10 seconds after re- moving the reverse gear.

The parking aid is part of the park assist system, therefore the information and
safety guidelines » page 140, Parking aid must be read and observed.
Park Assist (in the following referred to as the system) helps drivers park in suita- ble parallel and perpendicular parking places and also to manoeuvre out of paral-lel parking spaces.
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. 122 on
page 144 -
.
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.
143Assist systems
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 can cause
objects or people to not be recognized 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 leaving a parking space on loose or slippery surfaces (grav-
el, snow, ice, etc.) you may stray from the calculated road because of the sur-
face conditions. Therefore we suggest that you do not use the system in such
situations.
CAUTION
■ If other vehicles are parked behind the kerb or on it, the system can also 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, surfaces or structures of certain objects such as
wire mesh fences or powder snow cannot be recognised by the system.
■
The system function may be limited under adverse weather conditions (heavy
rain, water vapour, very low or high temperatures etc.).
■
The evaluation of the parking space and the parking procedure depends on the
circumference of the wheels on the vehicle. The system only works correctly if
the vehicle is fitted 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 143.
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
To prevent the speed from exceeding 7 km/h and to subsequently prevent can-
cellation of the parking procedure, automatic brake support is initiated. The park-
ing 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.

148
The Cruise Control System (CCS) maintains a set speed, more than 25 km/h, with-
out you having to actuate the accelerator pedal.
This is only possible within the range which is permitted by the power output and
braking power of the engine.
The warning light
illuminates in the instrument cluster when the cruise control
system is switched on.
WARNING■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) – risk of accident!■
The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■
Always deactivate the cruise control system after use to prevent the system
being switched on unintentionally.
CAUTION
■ The cruise control system is not able to maintain a constant speed when driving
in areas with steeper gradients. The weight of the vehicle increases the speed at which it travels. In such cases, a lower gear should be engaged or the footbrake
applied.■
It is not possible to switch on the cruise control system if the first gear or re-
verse gear is engaged (Vehicles fitted with a manual transmission)
