Tyre pressures
GRisk of accident
If the tyre pressure is too low, this:
Ihas a detrimental effect on road safety
Idamages or destroys the tyres
Imay cause tyre overheating or even
spontaneous combustion
You could lose control of the vehicle and
cause injury to yourself and others.
You should therefore check the tyre pres-
sures regularly before commencing a jour-
ney and correct them if necessary.
!Only use tyres and wheel rim sizes ap-
proved for your vehicle. These are specially de-
signed for use with the control systems, such
as ABS or ESP
®
.
iIn particular, also observe the tyre approval
regulations in each respective country.
These regulations may determine a specific
type of tyre for your vehicle or prohibit the use
of certain types of tyre, which are permitted in
other countries.
Also comply with the necessary tyre load-bear-
ing capacity and the speed index for your ve-
hicle.
Set the correct tyre pressure before load-
ing the vehicle. Once the vehicle is laden,
check the tyre pressures and correct them
if necessary.
When the vehicle is driven, the tempera-
ture of the tyre, and with it the tyre pres-
sure, will increase according to speed and
load.
You should therefore only correct tyre
pressures when the tyres are cold. Only
correct the tyre pressures when the tyres
are warm if:
Ithe levels fall below the values stated
in the table when the vehicle is laden
and the temperature of the tyre is tak-
en into account
Ithe levels fall below the values stated
in the table when the vehicle is unladen
and the temperature of the tyre is tak-
en into account
iTyre pressure changes by approximately
0.1 bar for every 10 °C change in outside tem-
perature. Remember to allow for this when
checking tyre pressures inside, particularly in
winter.
Example:
Inside temperature = approximately 20 °C
Outside temperature = approximately 0 °C
Tyre pressure to be set: specified tyre pressure
+0.2 bar
!The pressure difference between tyres on
any one axle must be no greater than 0.1 bar.
Observe the information on tyre pressure
in the “Safety”section (epage 56).
The tyre pressure values for an unladen/
laden vehicle depend on the permissible
axle loads that you will find on the identifi-
cation plate on the door frame of the driv-
er’s door .
