262Vehicle careIncorrect 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 3 291.
3. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 298.
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.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
After adjusting tyre pressure, select
the according tyre loading setting on
the page Tyre load in the Driver
Information Centre 3 112.
Temperature dependency The 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
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down tyre will show a decreased value,
which does not indicate an air leak.
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.

Vehicle's kerb weight depends on the
specification of the vehicle, e.g.
optional equipment and accessories. Refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The technical data is determined in
accordance with European
Community standards. We reserve
the right to make modifications.
Specifications in the vehicle
documents always have priority over
those given in this manual.
Engine identification
The technical data tables use the
engine identifier code. The engine
data table additionally shows the
engineering code.
Engine data 3 291.
To identify the respective engine, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The Certificate of Conformity shows
the engine identifier code, other
national publications may show the
engineering code. Check piston
displacement and engine power to
identify the respective engine.
