T ire s and w heel s
- Adjust the tire pressure to the load you are
carrying.
- Reinsta ll 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 a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should
I
adj ust 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*

A
WARNING
Incorrect tire pressures and/or underinf la-
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
II]
warning symbol appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla-
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin-
flation can also lead to sudden tire fa il-
ure, including a blowout and sudden de-
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire press ures fo r all t ires on the vehicle .
The applicable pressure values are locat-
ed on a sticker on the driver's side B-pil-
lar.
- Only when a ll ti res on the vehicle are fi l-
led to the correct pressure, the tire pres-
sure monitoring system* can work cor-
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified t ire pressure val ues
for the tires and the correct pressures for
the function of the ti re pressure monitor-
ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iving
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 cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle will not ha ndle well.
- If the tire is not flat and you do not have
to change a wh eel immediately, drive at
red uced speed to the nearest service sta-
tion to check the t ire pressure and add
air as required.
Q)
Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@
For the sake of the environment
Underinflated tires w ill also incre ase t he
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in-
clud ing a blowout and sudden deflation t ha t
can cause t he vehicle to crash.
Your safety and that of your passengers also
depends on making sure that load limits are
.,..
