structions for the navigation system .
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.

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.

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.

The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on. In the start-stop mode, the engine automatically switches to the vehicle's idle phase, e.g. when stopped at traffic lights. The engine restarts automatically
where necessary.
The system can work only if the following basic conditions are 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.
WARNING■ The brake servo unit and power steering only operate if the engine is run-
ning.■
Never let the vehicle roll with the engine switched off.
CAUTION
Always deactivate the START-STOP system before driving through wa-
ter » page 134 .Note■
If the driver's seat belt is removed for more than approx. 30 seconds or the driv-
er's door is opened during stop mode on vehicles with manual transmission or au- tomatic transmission (when the selector lever in position P), the engine must be
started manually » page 120.■
After manually starting the engine on vehicles with manual transmission, auto-
matic engine shut down is not possible until the vehicle has travelled the re-
quired minimum distance for START-STOPP mode.
■
If, on vehicles with automatic transmission, the selector lever positions D, S or N
are selected after driving in reverse, the vehicle will first need to achieve a speed
of over 10 km/h before automatic engine shut down can take place again.
■
Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out- doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable
temperature for proper operation of the START STOP system.
■
If the Climatronic is running in automatic mode, it is possible that under certain
conditions the engine may not switch off automatically.
Starting/shutting down the engine

The automatic start procedure takes place again. The warning symbol goes
out.
Further information on automatic transmission Engine shut down takes place when the selector lever is in positions 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. Start the engine by pressing the gas pedal or by moving
the selector lever into a different mode and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
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.
Operating conditions of the system
First read and observe the introductory information and safety warn-ings
on page 149.
The START-STOP system is very complex. Some of the procedures are hard to check without servicing.
No engine shut down is carried out
Before each STOP phase, the system checks whether certain conditions have
been met. No engine shut down takes place in the following situations.
› The engine has not reached the minimum temperature for START STOP mode.
› The temperature inside the vehicle has not reached the desired temperature
set in the air-conditioning system/heating.
› The external temperature is very low/high.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The parking aid/Park Assist is switched on.
› The charge state of the vehicle battery is too low.
› The stationary vehicle is on a steep slope or a steep downhill section.
› The idling speed is too high.
› The steering angle is too large (manoeuvring).
› The selector lever position
R is selected (e.g. when parking).
The warning symbol appears in the instrument cluster display.
The automatic start procedure takes place again
During the STOP phase, the engine fires up without any active driver intervention, e.g. in the following situations.
› The vehicle begins to roll, e.g. on a slope.
› The difference between the temperature setting of the air-conditioning sys-
tem/heating and the temperature of the interior is too large.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The brake pedal was pressed several times (the pressure in the braking system
is too low).
› The charge state of the vehicle battery is too low.
› The current consumption is too high.

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
151
Information messages
151WARNING■ 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 conditions or poor road conditions).■
The fatigue detection system is designed primarily for motorway driving.
Function
First read and observe the introductory information and safety warn-ings
on page 151.
The fatigue detection system advises the driver on the basis of information about
the steering behaviour, to take a break from driving. The system recommends 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 possible
fatigue of the driver, it recommends to take a break from driving.
The system deletes the stored baseline analysis if 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.
If none of these conditions are met or if the driving style is not changed, the sys-
tem recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the Assis-
tants menu option » page 28.
Information messages
First read and observe the introductory information and safety warn-
ings
on page 151.
The symbol will appear in the MAXI DOT display for a few seconds, along with
the following message.
Driver alert. Take a break!
