Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring.Remove the valve cap key from the
fuel filler flap and use it to unscrew the
valve cap.
On vehicles with tyre pressure
monitoring system, screw the adapter
to the valve.
Tyre pressure 3 206 and on the label
on the inside of the fuel filler flap.
The tyre pressure data refer to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be used with run-flat tyres.
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 3 202.
3. Identify the respective tyre.
