24 2 T ire s and wheel s
If the pressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your veh icle and in this manual and the k ind
of dr iving you p lan to do.
Ne ver exceed the m aximum inflat ion pres
s ur e liste d on th e tir e si dewall for any r ea
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the tires on your vehicle .
It is important to check the tire pressure when
the tires are cold.
- Read the required ti re p ressure from the tire
pressure label. The tire pressure labe l is lo
cated on the driver's side 8-p illar.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressu re ga uge on the valve.
- T he tire pressures sho uld on ly be chec ked
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
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I ch eck the tire pressur e?
The correct tire pressure is especially impor
tant at high speeds. The pressure should
therefo re be checked at least once a month
and a lways befo re start ing a journey. Do no t
forget to check the tire pressure for the spare
wheel
¢ page 257 .
When should I adju st the tire p res sures?
Adjust the tire p ressu re 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
store the new tire pressures in the tire pres
sure monitoring system*¢
page 253.
_& WARNING
Incorrect tire pressures and/or underinfla
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warn ing symbol
[I) appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla
tion can cause increased tire wear and
can affect the hand ling of the vehicle and
s topping abi lity.
- I nco rrect tire pressures and/or unde rin
f lation can a lso lead to sudden t ire fail
ure, including a blowou t and sudden de
flation, ca us ing loss of veh icle contro l.
- The drive r is responsible for the co rrec t
tire pressures for all tires on the veh icle.
The applicable pressure values are loca t
ed on a sticker on the driver's s ide 8 -pil
lar.
- On ly when all tires on the vehicle are fil
led to the correct pressure, the tire pres
sure mon itoring* system can work cor
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r
ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udde n tire f ailure
and loss of cont ro l.
- Excessive speed and/overloading can
cause heat build- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. ..,
