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
138
Activation / deactivation
140
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.

This chapter contains information on the following subjects:
Function
141
Activation/deactivation
141WARNING■ The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they may not be recognised by the system sensors.■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. in front or behind your vehicle.
Such obstacles may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the system signals. Thus, these objects or people who wear such clothing are not recognised by the System sensors.
■
External sound sources can have a detrimental effect on the system. Under
adverse conditions, this can cause objects or people to not be recognized by
the system.
CAUTION
■ If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
also indicated by the symbol flashing in the button » Fig. 119 on page 141 .
Seek help from a specialist garage.■
The sensors must be kept clean (free of ice, etc.) to enable the system to oper-
ate properly.
■
The system function may be limited under adverse weather conditions (heavy
rain, water vapour, very low or high temperatures etc.).
■
Additionally installed modules such as bicycle carriers can impair the function of
the parking aid.
Note
■ The signal tones for front obstacle recognition are factory-set to be higher than
for rear obstacle recognition.■
If not all fields around the vehicle are shown after the system is activated, the
vehicle will need to be moved a few metres forwards or in reverse.
■
The sound of the park-assist can be adjusted via the MAXI DOT display in the
Assistants menu option » page 29.
■
If the system is activated and the selector lever of the automatic gearbox is in
position P (the vehicle cannot move), the warning tone is interrupted and no ob-
stacles are displayed.

WARNING■
The system can not replace the driver's attention. Careless or uncontrolled
use of the system can cause accidents and serious injuries.■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions.
■
Make sure that the camera lens is not dirty or covered, otherwise the sys-
tem function can be significantly impaired. For information on clean-
ing » page 191 , Camera lens
■
The camera lens distorts and enlarges the field of view of the difference in
eye sight. Objects are displayed deformed.
CAUTION
■ The system can be used only if tailgate is fully closed.■Some items, such as thin columns, chain link fences or lattice may not be repre-
sented adequately in terms of display resolution.■
It is only a two-dimensional display. Therefore, protruding objects or roadway
depressions, for example, may not be recognised due to lack of space depth.
■
In a crash or damage the vehicle's rear camera can possibly deviate from the
correct position. If this is the case, have the sensor checked by a specialist ga-
rage.
CAUTIONWe recommend that you do not use the system in the following situations.■The display is poor, such as when visibility is poor or in the event of a dirty lens.■
The rear of the vehicle is heavily loaded (the area displayed behind the vehicle is
too short).
CAUTION
The objects shown in the display can be closer or even further away than they ap-
pear. This is especially the case in the following situations.■
When driving from a horizontal surface into a slope or a depression.

Information messages
146
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.
Finding a parking spaceFig. 122
System button / display
First read and observe the introductory information and safety warn-
ings
on page 143.
The search for a suitable parking space takes place while the display is switched
off. If the display is not switched on using the symbol button until the driver
drives past the parking space, the system can assess and display this parking
space.

arises.
› Speed of more than 7 km/h exceeded during the manoeuvring procedure.
› System button pressed.
› Engagement of the ASR system.
› TCS system switched off.
› Intervention of the driver in the automatic steering procedure (stops the steer-
ing wheel).
› There is a system fault (system temporarily not available).
› Automatic braking for damage limitation.
If any of the above events occurs, the following warning message is dis-
played. » page 146 .
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.
