Assist systems
General information
WARNING■The assistance systems only serve to support and do not relieve the driv-
er of the responsibility for driving the vehicle.■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate or set the assistance systems so that you have
the car fully under control in every traffic situation - risk of accident!

The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 31, Warning lights .
WARNINGThe general information relating to the use of assistance systems must be
observed » page 110, in section General information .
Stability Control (ESC)
Read and observe
on page 110 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehiclestarts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the warning light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 110 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain 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 pres-
sure on the brake pedal.
Engine drag torque control (MSR)
Read and observe
on page 110 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
110Driving
Traction control (TCS)Fig. 131
System button: Vehicle with ESC / vehicle without ESC
Read and observe
on page 110 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the drive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
The deactivation/activation of TCS can be carried out, depending on equip-
ment, in one of the following ways. ▶ By pressing the
» Fig. 131 button.
▶ By pressing the
» Fig. 131 button.
With deactivation , the warning light
lights
up in the instrument cluster and
an appropriate message is displayed in the instrument cluster.
With activation , the warning light
is extinguished and an appropriate mes-
sage is displayed in the instrument 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.
Electronic Differential Lock (EDL)
Read and observe
on page 110 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes a spinning wheel if required and transfers the drive power force to the
other drive wheel. Driving becomes easier on road surfaces with different trac-
tion under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
Driver Steering Recommendation (DSR)
Read and observe
on page 110 first.
In critical situations, the DSR provides the driver with a steering recommenda-tion in order to stabilise the vehicle. DSR is activated, for example, on the right
and left vehicle side when braking sharply on different road surfaces.
Brake Assist (HBA)
Read and observe
on page 110 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is re-
leased.
Hill Start Assist (HHC)
Read and observe
on page 110 first.
When moving off on a gradient, HHC allows you to move your foot from thebrake pedal to the accelerator pedal without the vehicle rolling downhill.
The vehicle is braked by the system for about 2 seconds after releasing the
brake pedal.
111Assist systems
The following functions are integrated in the OFF ROAD mode.
▶ Downhill Drive Support » page 113.
▶ TCS OFF ROAD » page 113.
▶ EDL OFF ROAD » page 113.
▶ ABS OFF ROAD » page 113.
▶ Start-Off Assistant » page 114.
Note
If the engine stalls while driving and is started again within 30 seconds, then
OFF ROAD mode will be automatically activated.
Hill Descent Assistant
Read and observe
and on page 112 first.
The hill descent assistant (hereinafter referred to as assistant), with its auto-
matic braking action on all wheels, ensures a constant speed is maintained on
a steep slope when driving forwards and reversing.
During an intervention of the Assistants, the warning light flashes in the in-
strument cluster.
The assistant is automatically engaged under the following conditions. The engine is running.
For vehicles with Manual transmission the shift lever is in the neutral po-
sition and or the 1st, 2nd, 3rd gear, or reverse gear is engaged.
On vehicles with an automatic transmission , the selector lever is in the R,
N, D, S position or in the Tiptronic position.
The downhill gradient is at least 10 % (when driving over sleepers, the lim-
it can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
Driving speed
Initiate the downhill decent at a reasonable speed up to 30 km / h the hill de-
scent assist maintains this speed when driving downhill constant.
The assistant can maintain constant speed of about 2 - 30 km / h.
If a forwards or reverse gear is engaged for vehicles with Manual transmis-
sion , the speed must be high enough to avoid stalling the engine.
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 se-
lector lever in the N position. The engagement of the assistant is resumed af-
ter the pedal is released.WARNINGFor the correct operation of the assistant the road surface must be suffi-
ciently adherent. The assistant cannot properly fulfil its function on slushy
soil due to physical reasons (e.g. ice or mud). - there is a risk of an accident!
Note
During an active intervention of the assistant, the brake lights do not light up.
TCSOFF ROAD
Read and observe
and on page 112 first.
The ASR OFF ROAD makes starting and driving on an unpaved surface easier
as it partially allows wheel-spin.
Note
When disabled, the TCS » page 111 OFF ROAD mode works without the support
of the TCS OFF ROAD.
EDS OFF ROAD
Read and observe
and on page 112 first.
The EDS supports OFF ROAD vehicle traction when driving on a surface withdifferent 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.
ABS OFF ROAD
Read and observe
and on page 112 first.
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 be-
fore a “wedge” of piled material, which shortens the braking distance.

its initial position when the tow bar is removed and will rest on the tow bar
and not engage into the ready position. The ball head then needs to be
brought into this position before the next time it is fitted » page 125.
The ball rod must be cleaned before storing in the box with the vehicle tool
always.WARNINGNever allow the tow bar to remain unsecured in the boot. This could cause
damage to the boot upon sudden braking, and could put the safety of the
occupants at risk!

Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake.WARNINGAlways drive particularly carefully with the trailer.
CAUTION
With frequent towing, the vehicle is excessively loaded so this must also be
checked between service intervals.
Anti-theft alarm system
The alarm is triggered if, with a vehicle with activated anti-theft alarm (here-
after only warning system), the electrical connection to the trailer (accessory)
is interrupted.
Always switch off the anti-theft alarm system before a trailer (accessory) is
coupled or uncoupled » page 51.
Conditions for including a trailer (accessory) in the anti-theft alarm system. The vehicle is factory-fitted with an anti-theft alarm system and a towing
