Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system has three ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approx. 40 cm, the sound is
continuous.
Deactivation
The system automatically switches
off when reverse gear is disengaged.
The system might not detect the
obstacle when the vehicle is driven above a 10 km/h.
Driving and operating123Fault
In the event of a fault in the system,
control indicator r illuminates in the
instrument cluster 3 70.
Additionally if the system does not
work due to temporary conditions like
snow covered sensors, r
illuminates.
Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
● No active steering.
If the driver is performing these
actions, no warning will be issued.

152Vehicle careCaution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by
pressing the buttons on the turn
signal lever.
Press MENU to select the Vehicle
Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 150.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 71.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 182.
Vehicle care153If w flashes for 60-90 seconds then
illuminates continuously, there is a fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 79.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these tyres.
Control indicator w illuminates. For
the further three tyres, 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 to the tyre information label
or tyre pressure chart 3 182, and
select the appropriate setting in the
menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 73 . This setting is
the reference for the tyre pressure
warnings.The Tyre Load menu only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Lo for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Hi for full loading.
154Vehicle careTyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new tyre/wheel position after
rotating the tyres or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing the tyre pressure sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a relearn tool, in the
following order: left side front wheel,
right side front wheel, right side rear
wheel and left side rear wheel. The
turn signal light at the current active
position is illuminated until sensor is
matched.
Consult a workshop for service or
purchase a relearn tool. There are
two minutes to match the first wheel
position, and five minutes overall tomatch all four wheel positions. If it
takes longer, the matching process stops and must be restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.
3. On vehicles with manual transmission automated: Press
and hold brake pedal. Move and
hold the selector lever for five
seconds in position N until P is
displayed in the Driver Information Centre. P indicates
that the sensor matching process can be started.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate that the sensor
identification code has been
Vehicle care155matched to the left side rear
wheel, and the tyre pressure
sensor matching process is no
longer active.
13. Turn off the ignition.
14. Set all four tyres to the recommended air pressure level
as indicated on the tyre
information label.
15. Ensure the tyre loading status is set according to the selected
pressure 3 73.
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).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and to make other
vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
