Car Pass
The Car Pass contains security
related vehicle data and should
therefore be kept in a safe place.
When the vehicle is taken to a
workshop, this vehicle data is needed in order to perform certain operations.Radio remote control
Used to operate:
■ Central locking system 3 25
■ Anti-theft locking system 3 34
■ Anti-theft alarm system 3 35
■ Load compartment 3 33
The remote control has a range of
approx. 5 metres. It can be restricted
by external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.
22Keys, doors and windows
Depending on model, the vehicle mayuse a 2 button or 3 button remote
control or an electronic key which
includes the functionality of the radio
remote control.
Electronic key system 3 23.
Fault
If the central locking system cannot
be operated with the remote control,
it may be due to the following:
■ Range exceeded
■ Battery voltage too low
■ Frequent, repeated operation of the
remote control while not in range,
which will require reprogramming
by a workshop
■ Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time
■ Interference from higher-power radio waves from other sources

Replace the battery as soon as the
range reduces.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
2-button and 3-button remote control

this event, press the Start/Stop button
for 2 seconds to stop the engine.
Central locking system 3 25.Retained power off
Press the Start/Stop button for more
than two seconds; the engine is
stopped while some functions, e.g.
Infotainment system, are available for
use for approx. 10 minutes.
These functions stop working when
the driver's door is opened and the
vehicle is locked.
Note
Always take the electronic key with you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 91 and a message in the
Driver Information Centre 3 91 when
the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
■ Fault in electronic key.
■ Electronic key out of reception range.
■ Battery voltage too low.
■ Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
■ Interference from higher-power radio waves from other sources.

158Vehicle care
Tyre pressures 3 192. Always inflate
tyres to the pressures shown on the
label on the driver's door frame.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 182.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 192.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
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.
Note
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 pressures in display The current tyre pressures can be
shown in the Driver Information
Centre 3 90.

Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 86 and a corresponding message
appears in the Driver Information
Centre. Stop vehicle and switch off
engine.
Tyre pressure 3 192, Tyre repair kit
3 162, Spare wheel 3 166, Wheel
changing 3 165.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. 3 seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving may be
required to complete the relearn
process.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.

Vehicle messages 3 91.
General information
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 162.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
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).
