Maximum tire pressures
Example: maximum permissible tire pres-
:

Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure
( page 248).

The actual values for tires are vehicle-

specific and may deviate from the values in

Important safety notes
Observe the notes on tire pressure

Information on air pressure for the tires on
your vehicle can be found:

Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows:
Remove the valve cap of the tire that is to
X
be checked.
Press the tire pressure gauge securely onto
X
the valve.
Read the tire pressure and compare it to
X
the recommended value on the Tire and
Loading Information placard on fuel filler
flap of your vehicle (
Y
The tire pressure is too low: increase the
X
tire pressure to the recommended value.
The tire pressure is too high: press down
X
the metal pin in the valve using the tip of a
pen, for example.
Air is released from the tire.
Check the tire pressure again with the tire
X
pressure gauge.
Screw the valve cap onto the valve.
X
Repeat these steps for the other tires.

Important safety notes

WARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire pressure
label on the inside of the fuel filler flap. If your
vehicle has tires of a different size than the
size indicated on the Tire and Loading Infor-
mation placard or the tire pressure label, you
should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale illuminates,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
flated tire causes the tire to overheat and can
lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stop-
ping ability.
