Tire inflation pressureChecking tire pressuresTire pressures in psi/kilopascal are
shown on the driver's door post and are
visible when the door is open.
Only check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
In the following tire inflation pressure
table, all pressures are specified in the
standard units of pressure, psi and kilo-
pascal, and apply to cold tires, i.e. tires
at ambient temperature.
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor so
that it can monitor the tire inflation
pressure, refer to page 87.

cle, you simultaneously deactivate/acti-
vate the anti-theft system and switch
the interior lamps on/off.

able to lock the doors from the inside,
always take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<
