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.
124Driving
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically » page 15, Brake system .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.

The handbrake indicator light
lights up when the handbrake is applied, provi-
ded the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the hand-
brake applied.
The following message is shown in the MAXI DOT display. Release parking brake!
The handbrake warning is activated if the vehicle is driven at a speed of more
than around 5 km/h for more than 3 seconds.
WARNINGPlease note that the handbrake must be fully released. A handbrake which is
only partially released can result in the rear brakes overheating. This can have a negative effect on the operation of the brake system – risk of accident!

Always depress the clutch pedal all the way down. This prevents uneven wear on the clutch.
The gear recommendation must be observed when changing gear » page 24.
Only engage reverse gear when the vehicle is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before reverse gear is engaged to
avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.

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 riskof 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 124.

Kickdown
The kickdown function allows you to achieve the maximum acceleration of your
vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activated
in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has reached
its maximum revolutions for this gear range.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control of
the vehicle – risk of accident!
Malfunction
First read and observe the introductory information and safety warn-
ings
on page 126.
Emergency programme
The transmission switches to the emergency programme, if there is a fault in the automatic gearbox system.
Indications of an activated emergency programme include the following.
› Only certain gears are selected.
› The reverse gear
R cannot be used.
› Shifting gears in Tiptronic mode is not possible.
Gearbox overheating
The gearbox may become too hot due to frequent repeated starting or stop-and-
go traffic, for example. Overheating is indicated by the warning light » page 14,
Clutches of the automatic gearbox are too hot .

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).
› Antilock Brake System (ABS)

› Hill Hold Control (HHC)
» page 138.
› Trailer stabilisation (TSA)
» page 158.
The ESC system cannot be deactivated. The
» Fig. 116 symbol button can only
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.
137Assist systems
The HBA is activated by very quick operation of the brake pedal. In order to ach-
ieve the shortest possible braking distance, the brake pedal must be applied firm-
ly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is released.
The ABS is activated faster and more effectively with the intervention of the HBA.
Hill Hold Control (HHC)
First read and observe the introductory information and safety warn-ings
on page 136.
When driving on slopes, HHC allows you to move your foot from the brake pedalto the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brakepedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is only ever
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.
OFF ROAD-mode
Introduction
This chapter contains information on the following subjects:
Operation

The OFF ROAD mode supports the driver when driving away from paved roads.
But even with OFF ROAD mode activated, your vehicle is never a true SUV.
WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. This would lead the OFF ROAD mode to lose its effectiveness - risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions.
■
The increased safety offered by the OFF ROAD mode must not tempt you to
take greater risks than otherwise - risk of an accident!
CAUTION
■ The OFF ROAD mode is not designed for the use on common roads.■All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure theOFF ROAD mode operates correctly.
Operation
First read and observe the introductory information and safety warn-
ings
on page 138.
The OFF ROAD mode is ready to intervene at speeds below 30 km / hr. The readi-
ness of the system is the warning light
displayed in the instrument cluster.
The following functions are integrated in the OFF ROAD mode.
› Downhill Drive Support.
› Start-Off Assist.
› ABS OFF ROAD.
› TCS OFF ROAD.
› EDL OFF ROAD.
Downhill Drive Support
The hill descent assistant, with its automatic braking action on all wheels, en-
sures a constant speed on a steep slope when driving forwards and reversing.
The speed maintained corresponds to the speed of the vehicle at the time the As- sistant was first engaged.
During an intervention of the Assistants, the warning light
flashes in the in-
strument cluster.
By pressing the accelerator or brake pedal, the speed can be increased or re- duced. This is true even if the shift lever is in the neutral position and the selector
lever in the N position.
138Driving
The intervention of the wizard is cancelled when you press the pedal and re-
sumed after the pedal is released again.
The hill descent assistant is automatically engaged under the following condi-tions.
The OFF ROAD mode is switched on and the warning light lights up in the
instrument cluster.
The vehicle engine is running and either the 1st, 2nd or 3rd gear, reverse gear
or no gear is engaged and the selector lever is in position R, N, D, S or Tip- tronic.
The downhill gradient is at least 10 % (when driving over sleepers, the limit can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
It is however a requirement that the vehicle has sufficient grip on the soil. The Downhill Drive Support cannot properly fulfil its function on slushy soil due to
physical reasons (e.g. ice or mud).
For vehicles with manual transmission, the speed is maintained as follows.
› 1st gear - approx. 8 1)
- 30 km/h
› 2nd gear - approx. 13 1)
- 30 km/h
› 3rd gear - approx. 22 1)
- 30 km/h
› Reverse gear - approx. 9 1)
- 30 km/h
› Neutral for driving forwards - as well as driving backwards - approx. 2 - 30 km/h
On vehicles with automatic transmission, the speed is maintained as follows.
› Position D, S, R or Tiptronic (for 1st, 2nd, 3rd gear - approx. 2 - 30 km/h
› Neutral for driving forwards - as well as reversing - approx. 2 - 30 km/h
Start-Off Assist
The assistant supports the driver when starting eg on a steep slope. When the
driver presses the accelerator, the maximum engine speed is electronically limited so that a gentle approach is possible.
The overspeed trip unit is automatically deactivated after terminating the start-
up procedure.
As part of the Assist System, the accelerator pedal is adapted in its characteristics for an easier start-off on slippery and loose soil.ABS OFF ROAD
The ABS OFF ROAD supports the driver when braking on an unpaved surface such
as gravel, snow, etc.
The system generated by a controlled locking of the wheels braked wheel before a “wedge” of piled material, which shortens the braking distance.
The system is only available, if the front wheels are in the straight-ahead posi-
tion.
The system operates at speeds of up to 50 km/h.
TCS OFF ROAD
The ASR OFF ROAD makes starting and driving on an unpaved surface easier as it partially allows wheel-spin.
EDL OFF ROAD
The EDS supports OFF ROAD vehicle traction when driving on a surface with dif- ferent grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with the
intervention of the standard EDS system.
Note
■ During an active intervention of the Downhill Drive Support, the brake lights do
not light up.■
When disabled, ASR » Fig. 116 on page 136 the OFF ROAD mode works without
the support of the ASR OFF ROAD.

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

.
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.
