The parking aid is part of the park assist system, therefore the information
and safety guidelines » page 156 , Parking aid must also be read and ob-
served.WARNING■ The system only serves as an assistance 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 spokes – risk of injury!
■
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.Functioning

162
The Cruise Control System (CCS) maintains a set speed, more than 25 km/h,
without you having to actuate the accelerator pedal.
This is only possible within the range which is permitted by the power output and braking power of the engine.
The warning light in the instrument cluster illuminates when the cruise con-
trol system is switched on.
WARNING■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) – there is a risk of an accident.■
The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■
Always deactivate the cruise control system after use to prevent the sys-
tem being switched on unintentionally.
CAUTION
■ The cruise control system is not able to maintain a constant speed when
driving in areas with steeper gradients. The weight of the vehicle increases the
speed at which it travels. In such cases, select a lower gear or slow the vehicle
using the footbrake.■
The cruise control system cannot be activated when first gear or reverse
gear is selected (vehicles with manual transmission).
■
The cruise control system cannot be activated when the selector lever is in
positions P, N or R (vehicles with automatic transmission).
■
The Cruise Control System may automatically switch off when some brake
assist systems (e.g. ESC) intervene, when the speed exceeds maximum permis-
sible engine speed, or a similar event takes place.

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.162Driving
Automatic engine shutdown takes place, segment display shows START STOP
ACTIVE or a check mark appears in the MAXI DOT display » Fig. 152 on
page 163 .
Automatic engine start›
Release the brake pedal.
The automatic start procedure takes place again.
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 even
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 releas-
ing 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 start-up of 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 turning) 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 162 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 has begun 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
165
Information messages
165WARNING■ 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 fatigue detection system is designed primarily for motorway driving.
Function
Read and observe
on page 165 first.
The fatigue detection system advises the driver on the basis of information
about the steering behaviour, to take a break from driving. The system recom-
mends a break at speeds of 65-200 km/h.
After the ignition has been switched on, the system evaluates the steering be-
haviour for 15 minutes. This baseline analysis is constantly compared with the
current steering behaviour.
If the system detects deviations from normal steering behaviour due to possi-
ble fatigue of the driver, it recommends taking a break from driving.
The system deletes the stored baseline analysis if one of the following con-
ditions 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.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the As-
sistants menu option » page 47.
Information messages
Read and observe
on page 165 first.
In MAXI DOT display the icon appears for a few seconds and the following
message.
Fatigue detected. Take a break!
An audible signal is also emitted.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
166
The tyre pressure monitoring function (hereinafter referred to only as a sys-
tem) monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light in the
instrument cluster illuminates and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 40 .
The system can only function properly if the tyres have the prescribed inflation
pressure and this pressure values are stored in the system.
WARNING■ Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 198.■
The system cannot warn in case of very rapid loss of tyre pressure, e.g. in
the event of a sudden puncture.
