When reversing, the area should
be free from obstacles which could impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle in
either the interior mirror, the driver's
sun visor or the Infotainment system
display.
9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse the vehicle by only looking at the display and checkthe surrounding area behind and
around the vehicle before
reversing.
The camera is typically installed on
the rear doors/tailgate, beneath the
number plate moulding.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.

lane (1) of the vehicle is shown in blue
on the Info-Display. It shows the path of the vehicle in accordance with the
steering angle.
Fixed lane display (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cmSettings
Settings, e.g. brightness, can be set
via the Infotainment system. Refer to
Infotainment system manual for
further information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged.
Fault
The rear view camera may not operate properly when:
● the surrounding is dark
● the sun or the beam of headlights
is shining directly into the camera lens
● ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth
● the rear doors/tailgate are not closed correctly
● the vehicle had a rear-end accident
● there are extreme temperature changes
Lane departure warning
The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. 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 and lane- change signals
● no active steering
If the driver is performing these
actions, no warning will be issued.

When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoring system
The Tyre Pressure Monitoring
System (TPMS) uses radio and
sensor technology to check tyre
pressure levels.Caution
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 TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressure chart 3 219.
Tyre pressures in display
The current tyre pressures can be
shown in the Driver Information
Centre (DIC) 3 89.With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 87 and a
corresponding message appears in
the DIC.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 219.
Page 180 of 233

178Vehicle careAfter inflating, some driving may be
required to update the tyre pressure
values in the DIC. 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 of all
four tyres.
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 flashes for
several seconds then illuminates
continuously together with control
indicator A 3 85 and a
corresponding message appears in
the DIC.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for
these wheels. For the further three
wheels, TPMS remains operational.Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.

Vehicle messages 3 90.
Puncture A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 85 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.
Tyre pressure 3 219, Tyre repair kit
3 180, Spare wheel 3 185, Wheel
changing 3 184.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the tyre information label and tyre
pressure chart are valid for cold tyres,
which means at 20 °C. The pressure
increases by nearly 1.5 psi for a10 °C temperature increase. This
must be considered when warm tyres
are checked.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. A cooled down tyre will show a decreased value, which does
not indicate an air leak.
Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the DIC by
pressing button on end of wiper lever. Press and hold button for approx.
Page 181 of 233

Vehicle care1795 seconds to initialise recalculation. A
corresponding message appears in
the DIC.
Several minutes of driving at a speed
above 25 mph may be required to
complete the relearn process. The
system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the DIC.

General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 180, Tyre chains
3 180.
External high-power radio equipment
could disrupt the TPMS.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.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 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.

194Vehicle careThe instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
