Park Assist (in the following referred to as the system) helps drivers park in
suitable parallel and perpendicular parking places and also to manoeuvre out
of parallel parking spaces.
The system takes over the steering movements when parking or driving out of
the parking space, the driver operates the pedals as well as the gear lever.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The parking aid is part of the park assist system, therefore the information
and safety guidelines » page 146 , Parking aid must also be read and ob-
served.
WARNING■ The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
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!

WARNING (Continued)■During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road because of the surface
conditions. Therefore we suggest that you do not use the system in such
situations.■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people to not be recog-
nised by the system.
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.
■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
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.
■
Do without the use of the system if snow chains or a spare wheel is moun-
ted.
■
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.
Note
We recommend performing the parking at a safe speed to about 5 km / h.

Operating Description
154
The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the GRA maintains the speed is referred to hereinafter as the
control .
WARNING■
The GRA only serves to support and does not relieve the driver of the re-
sponsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 154 first.
Basic requirements for start of control The GRA is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic gearbox, the selector lever must be in the
D or S position, or in the Tiptronic position.
The current speed must be higher than 20 km/hr.
This is only possible within the range which is permitted by the power output and braking power of the engine.
WARNINGIf the engine power and engine braking effect is insufficient to maintain
the set speed, vehicle operation must be taken over!

The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 144
Maxi DOT display: Engine is auto-
matically switched off / automat-
ic engine cut off is not possible
Read and observe on page 155 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If after stopping the car, the message START-STOP NOT POSSIBLE appears in
the segment display or the
» Fig. 144 check mark appears in the MAXI DOT
display, then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).

Note■If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.

Further information on automatic transmission
The automatic engine shut down takes place when the selector lever is in po-
sitions P, D , S and N and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after
you release the brake pedal. The engine starts automatically by pressing the
gas pedal or by moving the selector lever into a different mode and releasing
the brake pedal.
If the engine is off due to the automatic and the selector lever is put to the R
position then the automatic starts the engine.
If the gear selector is moved from position R to the position D, S or N, the vehi-
cle must reach a speed of more than 10 km / h before the automatic engine
shutdown starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 155 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle begins to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
157
Information messages
158
The fatigue detection system (hereinafter referred to only as system) recom-
mends the driver taking a break from driving when, because of the driver's
steering behaviour, driver fatigue can be detected.
WARNING■ For the driving ability is always the driver's responsibility. Never drive if
you feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 157 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
The system evaluates steering behaviour and recommends a break at speeds
of 65-200 km / h.
The system detects a break from driving when one of the following condi-
tions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
