Driving and operating203Indication 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.

204Driving and operatingDisplay indication
The instructions on the display show:
● General hints and warning messages.
● A hint when driving faster than 30 km/h 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 30 km/h during
parking slot search
● driving faster than 8 km/h 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.

258Vehicle careilluminates. 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 3 293, and select
the appropriate setting in Tyre Load
within the vehicle information menu
3 111. 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 40 to 100 km/h. 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).

270Vehicle care● A discharged vehicle battery canalready freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump
leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster vehicle battery with the same voltage (12 V). Itscapacity (Ah) must not be muchless than that of the discharged
vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
Lead connection order: 1. Connect the red lead to the positive terminal of the booster
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the negative terminal of the boostervehicle battery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.

Vehicle care271Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert the screwdriver in the slot at the
edge of the cap. Release the cap by
levering it out carefully.
The towing eye is stowed with the
vehicle tools 3 253.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 194, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
