The menu item Vehicle status is shown in the main menu of the MAXI DOT dis-
play whenever at least one fault message exists. After selecting this menu, the
first of the error messages is displayed. Several error messages are shown on the
display under the message e.g. 1/3. This indicates that the first of a total of three
error messages is being displayed.

Problem with the engine oil pressure
If the
symbol is shown in the MAXI DOT display, you must have your vehicle
checked immediately by a specialist garage. The information about the maximum
permissible engine speed is displayed together with this symbol.
Clutches of the automatic gearbox are too hot
A
symbol in the MAXI DOT display indicates that the temperature of the auto-
matic gearbox clutches is too high.
The following message is shown in the MAXI DOT display.
Gearbox overheated. Stop! Log book!
do not continue to drive! Stop the vehicle, switch off the engine, and wait until
the
icon goes out – risk of gearbox damage! You can continue your journey as
soon as the symbol disappears.
WARNINGIf you have to stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warning
light system » page 56.Note■
If the MAXI DOT display shows warning messages, these messages must be
confirmed in order to access the main menu » page 23 .■
As long as the operational faults are not rectified, the symbols are always indi-
cated again. After they are displayed for the first time, the symbols continue to be indicated without any extra messages for the driver.

14Using the system
The HBA is activated by very quick operation of the brake pedal. In order to ach-
ieve the shortest possible braking distance, the brake pedal must be applied firm-
ly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is released.
The ABS is activated faster and more effectively with the intervention of the HBA.
Hill Hold Control (HHC)
First read and observe the introductory information and safety warn-ings
on page 150.
When driving on slopes, HHC allows you to move your foot from the brake pedal
to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brakepedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator pedal. Ifthe vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active on slops of >5 % if the driver door is closed. HHC is only everactive on slopes when in forward or reverse start off. When driving downhill, it is
inactive.
Parking aid
Introduction
This chapter contains information on the following subjects:
Function
153
Activation/deactivation
153WARNING■ The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they may not be recognised by the system sensors.■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. in front or behind your vehicle.
Such obstacles may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the system signals. Thus, these objects or people who wear such clothing are not recognised by the System sensors.
■
External sound sources can have a detrimental effect on the system. Under
adverse conditions, this may cause objects or people to not be recognised by
the system.
CAUTION
■ If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
also indicated by the symbol flashing in the » Fig. 132 on page 153 button.
Seek help from a specialist garage.■
The sensors must be kept clean (free of ice, etc.) to enable the system to oper-
ate properly.
■
Additionally installed modules such as bicycle carriers can impair the function of
the parking aid.
Note
■ The signal tones for front obstacle recognition are factory-set to be higher than
for rear obstacle recognition.■
The sound of the park-assist can be adjusted via the MAXI DOT display in the
Wizards menu option » page 29.
■
If the system is activated and the selector lever of the automatic gearbox is in
position P (the vehicle cannot move), the warning tone is interrupted and no ob-
stacles are displayed.

Range of sensors / system button
First read and observe the introductory information and safety warn- ings
on page 152.
The parking aid (hereafter referred to solely as system) only works when the igni- tion is switched on.
The system supports the driver via audible signals, via the display on the radio or via the factory-installed navigation system when parking and manoeuvring » Ra-
dio user guide, Navigation system user guide.
The system uses ultrasound waves to calculate the distance between the bumper
and an obstacle. The ultrasound sensors are located on the front/rear bumper.
Explanation of graphic - range of sensors in the vicinity of the vehicle
Area » Fig. 132Range of sensors a)A120 cmB60 cmC160 cmD60 cmEb)60 cma)
These are only the approximate ranges of sensors.
b)
Applies only for vehicles with 12 sensors.
The interval between the acoustic signals becomes shorter as the clearance is re-
duced. A continuous tone sounds from a distance of approx. 30 cm - danger area.
From this moment on do not continue driving!
The length of the vehicle can be increased with an installed detachable towing device. The danger area thus begins at a distance of around 35 cm on vehicles
equipped with a factory-fitted towing device.
Towing a trailer
On vehicles equipped with a factory-fitted towing device, only system areas A
and
B
» Fig. 132 are active when towing a trailer.
Activation/deactivation
First read and observe the introductory information and safety warn-
ings
on page 152.
The system is automatically activated by selecting reverse gear or pressing the
» Fig. 132 on page 153 symbol button. The symbol
lights up in the button;
activation is confirmed by a brief acoustic signal.
The system is deactivated by moving out of reverse gear or by pressing the
symbol button, or is deactivated automatically at a speed of over 10 km/h (the
symbol in the button goes out).
On vehicles which only have rear sensors , the system can only be deactivated by
moving out of reverse gear.

The parking aid is part of the park assist system, therefore the information and
safety guidelines » page 152, 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.
