Driving and operating201GSi models only
In vehicles with automatic
transmission, the driver must control
acceleration and gear shifting, while
braking and steering is done
automatically.
Advanced parking assist is always
combined with front-rear parking assist. Both systems use the same
sensors in the front and rear bumper.
The system has six ultrasonic parking sensors each in both the rear and
front bumper.
Activation of advanced parking assist
Advanced parking assist can only be
activated when driving forwards.
When searching for a parking slot, the system is ready to operate with a
short press of (.
The system recognises and
memorises 10 m for parallel parking
slots or 6 m for perpendicular parking
slots in the parking assist mode.
The system can only be activated and
searches for a parking slot at a speed
up to 18 mph.
Advanced parking assist may not be
activated when driving on very steep
inclines.
FunctionalityParking slot searching mode,
indication in the Driver Information
Centre
Select parallel or perpendicular
parking slot in Driver Information
Centre by long press on (.
The system is configured to detect parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
lights on the driver side.

202Driving and operatingIndication in the Info Display
Select parallel or perpendicular
parking slot by tapping the respective icon on the display.
Select parking side by tapping the
respective icon on the display.
When a slot is detected, a visual
feedback on the Info Display and an
acoustic signal is given.
If the driver does not stop the vehicle after a parking slot is proposed, the
system starts to search for another
suitable parking slot.
Park guiding mode
The parking slot suggestion of the system is accepted when the vehicle
is stopped by the driver within ten
metres for parallel parking slots or
six metres for perpendicular parking
slots after the message to stop the car
is indicated. The system calculates
the optimal path into the parking slot.A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle with manual transmission is steered into the slot
automatically by giving the driver
detailed instructions for braking,
accelerating and gear shifting. With
automatic transmission the vehicle is
steered into the slot automatically by
giving the driver detailed instructions for accelerating and shifting forward
or reversing. The driver must keep
hands away from the steering wheel.
During park guiding mode the
manoeuvring speed is limited.
Always pay attention to the signals of
the front-rear parking assist.
Continuous signal indicates that the
distance to an obstacle is less than approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.

● General hints and warning messages.
● A hint when driving faster than 18 mph during parking slot
searching mode.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The demand to shift into reverse or first gear, or R or D with
automatic transmission.
● The demand to stop or to drive slowly.
● For some of the instructions a progress bar is shown in the
Driver Information Centre.
● The successful completion of the
parking manoeuvre indicated by
a pop-up symbol and a chime.
● The cancelling of a parking manoeuvre.Display priorities
Advanced parking assist indication in
the Driver Information Centre can be inhibited by vehicle messages with a
higher priority. After approving the
message 9 on the steering wheel,
advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
● a short press of (
● parking manoeuvre successfully ended
● driving faster than 18 mph during
parking slot search
● driving faster than 5 mph during parking guidance
● driver interference on steering wheel detected
● steep hill incline detected
● exceeding maximum number of gear changes: eight cycles when
parallel parking or five cycles
when perpendicular parking
● switching off the ignitionDeactivation by the driver or by the system during manoeuvring will beindicated by a message on the
display. Additionally, an acoustic
signal sounds.
Automatic transmission:
If advanced park assist is deactivated
during the parking manoeuvre or
manoeuvre is finished successfully,
the assist holds the vehicle in position
until one of the following conditions
occurs:
1. brake pedal is applied
2. electric parking brake is activated
3. selector lever is set to P
Fault
A message appears when:
● There is a fault in the system.● The driver did not successfully complete the parking
manoeuvre.
● The system is not operational.
● Any of the deactivation reasons described above apply.

Vehicle care257illuminates. For the further three
wheels the system remains
operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor, replace
valve core and sealing ring. For the
clipped sensor, replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according tyre information label or
tyre pressure chart 3 291, and select
the appropriate setting in Tyre Load
within the vehicle information menu
3 110. This setting determines the
reference pressures for the tyre
pressure warnings.The Tyre Load menu only appears
when the vehicle is at a standstill and the parking brake is applied. On
vehicles with automatic transmission
the selector lever must be in P.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Auto learn function After changing wheels or wheel
positions the vehicle must be
stationary for approx. 20 minutes,
before the system recalculates. The
following relearn process takes up to
10 minutes of driving in a speed range
of 25 to 60 mph. Avoid to drive outside
of this range for a longer time. If
possible, use a country road or similar which allows continuous driving.
During relearn process $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a failure message is
displayed in the Driver Information
Centre. w will flash for 60 seconds
and then illuminate continuously.
If this happens, repeat learning
process. Keep your vehicle stationary for approx. 20 minutes and then drive
again for 10 minutes as described
above.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
