together with the rear view camera
when a certain forward speed is
exceeded or if reverse gear is not
engaged for approx. 10 seconds.

Vehicle care241
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 drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 269.
3. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 289.
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.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition. After adjusting tyre
pressure switch on ignition and select the according setting on the page
Tyre load in the Driver Information
Centre, 3 107.
Tyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.
Caution
Tyre pressure monitoring system
warns just 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.
Select the Tyre pressure monitoring
page under the Info Menu in the
Driver Information Centre 3 107

242Vehicle care
System status and pressure warningsare displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 104.
If w lights up, stop as soon as
possible and inflate the tyres as
recommended 3 289.
After inflating driving may be required
to update the tyre pressure values in
the Driver Information Centre. During
this time w may light up.
If w lights up at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
Vehicle messages 3 116.
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 spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
illuminates. 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.
External high-power radio equipment
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 clipped
sensor replace complete valve stem.Vehicle loading status
Adjust tyre pressure to load condition according tyre information label or
tyre pressure chart 3 289, and select
the according setting in the Tyre
loading page under the Settings
menu in the Driver Information Centre 3 107.
Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
