Tire inflation pressure

Safety information

It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.

Checking the pressure

Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.

Check the tire inflation pressure regularly
Check the tire inflation pressure regularly

and correct it if necessary, even in the compact
wheel*: usually twice monthly or before embark‐
ing on a long trip. If you fail to observe this pre‐
caution, you may be driving on tires with incor‐
rect tire pressures, a condition that may not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci‐
dent.
Do not drive with depressurized or flat tires, ex‐
cept for run-flat tires. A flat tire will seriously im‐
pair your vehicle's handling and braking re‐
sponse. Attempts to drive on a flat tire can lead
to a loss of control over the vehicle.◀

After adjusting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page

90

, or

reinitialize the Flat Tire Monitor, refer to
page

88

.

The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient

ice center.
For correct identification of the right tire inflation
pressures, observe the following:

Tire sizes of your vehicle.

Maximum allowable driving speed.

Tire inflation pressures for driving up to

100 mph or 160 km/h

For normal driving up to 100 mph/160 km/h, ad‐
just pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.

Do not exceed the maximum permissible
speed

The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀

Tire inflation pressures for driving

above 100 mph or 160 km/h

Adjust the tire inflation pressures
To drive at maximum speeds in excess of

100 mph/160 km/h, adjust pressures to the re‐
spective tire inflation pressures listed on the fol‐
lowing pages in the column for traveling speeds
including those exceeding 100 mph or 160 km/
