Avoidtire pressures thatare too high in all
the tires, including the spare wheel.
Overinflated tiresmay:
R
increase the braking distance
R
adverselyaffect handling
R
wear excessivelyand/or unevenly
R
have an adverse effect on ridecomfort
R
be more susceptibletodamage
Maximum tire pressures
:
Example: maximumpermissibletire pres-
sure
Never exceed the maximumpermissibletire
inflation pressure. Alwaysobserve the recom-
mended tire pressure for your vehiclewhen
adjusting the tire pressure (Y page 271).

Checkingthe tire pressures
Important safety notes
The tire pressure monitor does not warn you
of:
R
incorrectly set tire pressure
R
sudden loss of tire pressure, e.g.from afor-
eign object thathas penetrated the tire

Informationonair pressure for the tireson
your vehiclecan be found:

on the vehicle's Tire and Loading Informa-
tionplacard on the B-pillar

in the "Tire pressure" section
Checkingtire pressuresmanually
To determine and set the correct tire pressure,
proceedasfollows:
X
Remove the valve cap of the tire thatisto
be checked.
X
Press the tire pressure gaugesecurelyonto
the valve.
X
Read the tire pressure and compareittothe
recommendedvalue on the Tire and Loading
Informationplacard or the tire pressure
table (Y page 271).
X
If the tire pressure is too low, increase the
tire pressure to the recommendedvalue.
X
If the tire pressure is too high, release air.
To do so, press down the metalpin in the
valve,using the tip of apen for example.
Thencheck the tire pressure againusing the
tire pressure checker.
X
Screw the valve cap onto the valve.
X
Repeat thesestepsfor the othertires.
Tire pressure loss warning system

pressure using the rotational speed of the
wheels.Thisenables the system to detect sig-
