- Read the requir ed tire pressure from the tire
pressure label. The tire pressure label is lo-
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
t ire inflat ion pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man-
ufactured . For recommended tire pressures
for normal load conditions, please see chap-
ter ~

- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carry ing.
- Reinstall the valve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a journey .
When should
I
adjust the tire pressures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then initi-
alize the new tire pressures in the tire pres-
sure monitoring system* ~

WARNING
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the
[9]
warning symbol appears in
the instrument cluster, stop and insp ect
the tires.
- Incorrect tire pressure and/or underinfla-
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability.

- Incorrect tire pressures and/or underin-
flation can also lead to sudden tire fail-
ure, including a blowout and sudden de-
flation, causing loss of vehicle control.
- The driver is responsib le for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat-
ed on a sticker on the driver's side B-pil-
lar.
- Only when all tires on the vehicle are fil-
led to the correct pressure, the tire pres-
sure monitoring system* can work cor-
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor-
ing system*.
- Always inflate tires to the recommended
and correct tire pressure before driving
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading
can
cause heat build-up, sudden tire failure
and loss of control.
- If t he tire pressure is too low or too high,
the t ires will wear prematurely and the
vehicle will not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately , drive at
reduced speed to the nearest service sta-
tion to check the tire pressure and add
air as required.
(D
Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely
mounted on the valve.
