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 system.
Unscrew the valve cap.

on the front left 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.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.

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.
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.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Center.
The menu can be selected by the
buttons on the turn signal lever.
