WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure , loss of control, collision, serious personal injury or even
death .
When the warning symbol
(l)
appears in the instrument
cluster, stop and inspect the tires .
Incorrect tire pressure and/ or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation,
causing loss of vehicle control .
&
WARNING (continued )
The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side B-pillar.
Only when all tires on the vehicle are filled to the correct pres-
sure, the tire pressure monitoring system can work correctly.
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 pres-
sures for the function of the tire pressure monitoring system .
Always inflate tires to the recommended and correct tire pres-
sure 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 the tire pressure is too low or too high, the tires 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 station
to check the tire pressure and add air as required.
