So that an engagement of the OFF ROAD mode can take place, the following
conditions must be met.
The OFF ROAD mode is enabled.
The vehicle is moving at a speed of less than 30 km/h. The warning light
illuminates in the instrument cluster.
The following functions are integrated in the OFF ROAD mode.
▶ Downhill Drive Support » page 130.
▶ TCS OFF ROAD » page 130.
▶ EDL OFF ROAD » page 130.
▶ ABS OFF ROAD » page 130.
▶ Start-Off Assistant » page 131.
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 129 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 129 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 » Fig. 140 on page 127 OFF ROAD mode works without
the support of the TCS OFF ROAD.
EDS OFF ROAD
Read and observe
and on page 129 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 129 first.
The ABS OFF ROAD supports the driver when braking on an unpaved surface
such as gravel, snow, etc.

Park Assist (hereinafter referred to as system) helps drivers park in suitable
parallel and perpendicular parking places or also to manoeuvre out of parallel
parking spaces.
The system takes over the steering movements when parking or leaving a
parking space. The driver operates the pedals and the shift lever or gear selec-
tor.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The Park Assist is an extension of the parking aid » page 131 and operates on
the basis of data collected by the ultrasonic sensors.
For this reason, the chapter on the parking aid is to be read carefully and the safety notes are to be observed.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road. Therefore we suggest that
you do not use the system in such situations.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends 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.
■
Abstain from using the system when the vehicle is fitted with snow chains or
a temporary spare wheel.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
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.
Note
■ We recommend performing the parking at a safe speed to about 5 km / h.■The driver can stop the parking process at any time by pressing the symbol
key
» Fig. 149 on page 136 or by a driver steering intervention.
Functioning
Read and observe
and on page 135 first.
The system support is provided in the following manner.▶ While the parking space search is going on, a measurement and evaluation of
the parking space size is completed.
▶ Suitable parking spaces are shown in the display of the instrument cluster
(hereinafter only in the display).
135Assist systems

In vehicles with tyre pressure monitoring, save tyre pressure values» page 141.WARNING■
If, you get a puncture and a spare tyre has to be mounted with opposite
direction of rotation, then drive carefully. The best properties of the tyre
are no longer present in this situation.■
If the dimensions or design of the spare wheel differ from the tyres fitted
to the vehicle (e.g. winter tyres or low-profile tyres), it must only be used
briefly in the event of a puncture and if an appropriately cautious style of
driving is adopted.
■
Never use the temporary spare wheel if it is damaged.
Spare wheel
Read and observe
on page 176 first.
A yellow warning label is always displayed on the rim of the temporary spare
wheel.
Please note the following if you intend to use the temporary spare wheel. ▶ The warning label must not be covered after installing the wheel.
▶ Be particularly observant when driving.
▶ The temporary spare wheel is inflated to the maximum inflation pressure for
the vehicle » page 176.
▶ Only use this temporary spare wheel to reach the nearest specialist garage,
since it is not intended for permanent use.
If you need to use a spare wheel, make sure to fit a standard wheel of the ap-
propriate dimensions and design as soon as possible.
In vehicles with tyre pressure monitoring, save tyre pressure values » page 141.
WARNING■
Never drive with more than one spare wheel mounted!■Only use the spare wheel while absolutely necessary.■
Avoid accelerating at full throttle, sharp braking and fast cornering.
■
The snow chains cannot be used on the spare wheel.
■
If the dimensions or design of the temporary spare wheel differ from the
tyres fitted, never drive faster than 80 km/h (or 50 mph).
■
Never use the emergency spare wheel if it is damaged.
■
Observe instructions on the warning sign of the emergency wheel.
Tyre label
Read and observe
on page 176 first.
Only use radial tyres of the same type, size (rolling circumference) and treadpattern on one axle on all four wheels.
When mounting new tires the tires have to be replaced axle by axle.

Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
▶ Switch off the ignition and the relevant lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
A stowage compartment for replacement bulbs is located in a box under the floor covering in the luggage compartment.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
In case of failure of a xenon gas discharge lamp or an LED diode, visit a special- ist garage.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 165.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
