WARNING
Underinflated tires:
R
jeopardize driving safety
R
damage or destroy the tires
R
may cause tire overheating or even
spontaneous combustion
You could lose control of your vehicle and
injure yourself and other persons.
For this reason, check the tire pressure
regularly before starting a journey and correct
it if necessary.
Correct the tire pressure before loading. If the
vehicle is loaded, check the tire pressure, and
correct it if necessary.
While driving, dependent on driving speeds
and load, the tire temperature and with it, the
tire pressure rise.
You should thus only correct tire pressures
when the tires are cold. If the tires are warm,
you may only correct tire pressures when:
R
taking the respective tire temperatures into
consideration with the vehicle laden, the
values apparent from the tire pressure
table are not exceeded.
R
the levels fall below the values stated in the
tire pressure table when the vehicle is
unladen and the temperature of the tire is
taken into account.
The tires can be deemed to be cold if the
vehicle has been parked for at least 3 hours
or if it has been driven for less than 1 mile
(1.6 km) at an outside temperature of
approximately 68 ‡ (20 †).
i
The tire pressure changes by about
10 kPa (0.1 bar/1.5 psi) for each 18 ‡
(10 †) change in the air temperature.
Remember to allow for this when checking
tire pressures inside, particularly in winter.
Example:
Room temperature = approximately 68 ‡
(20 †)
Outside temperature = approximately
32 ‡ (0 †)
Tire pressure to be set: prescribed tire
pressure +20 kPa (+0.2 bar/+3 psi).
!
The pressure difference between tires on
any one axle must be no greater than
10 kPa (0.1 bar/1.5 psi).
A tire pressure of less than 300 kPa
(3.0 bar/43.6 psi) is not permissible.
The tire pressure values in the following table
apply to all load conditions up to the
maximum permissible gross vehicle weight
and only to the specified original tires in cold
condition. The values are determined by the
permissible axle loads found on the vehicle
identification plate on the driver seat frame
(Y page 285).
i
Additionally, you will find the stipulated
tire pressure values on the tire data label
on the B-pillar on the driver's side of your
vehicle (Y page 286).
