pressure can be checked in the on-board
computer.
G
Warning!
Should the tire pressure drop repeatedly:
R
check the tire for foreign bodies.
R
check whether the wheel is losing air or the
valve is leaking.
R
make sure that only a valve cap approved
by Mercedes-Benz is installed on the tire
valve.
tire pressure that is too low have a negative
effect on vehicle safety, which could lead you
to cause an accident.
Only correct tire pressures when the tires are
cold. The tires are cold when the vehicle has
been parked for at least three hours or has
been driven less than 1 mile (1.6 km) in this
time. The tire temperature changes
depending on the outside temperature, the
vehicle speed and the tire load. A change in
tire temperature of 18 ‡ (10 †) changes the
tire pressure by approximately 10 kPa
(0.1 bar/1.5 psi). Take this into account when
checking the pressure of warm tires and only
correct the tire pressure if it is too low for the
current operating conditions. If you check the
tire pressure when the tires are warm, the
resulting value will be higher than if the tires
were cold. This is normal. Do not reduce the
tire pressure to the value specified for cold
tires. The tire pressure would otherwise be
too low.
Comply with the recommended tire pressure
specifications for cold tires on the Tire and
Load Information placard on the B-pillar on
the driver's side of your vehicle.
i
The following data on the Tire and Load
Information placard is given as an example.
Tire pressure specifications are vehicle-
specific and may deviate from the data
shown here. The tire pressures applicable
to your vehicle can be found on the Tire and
Loading Information placard on your
vehicle.
On the Tire and Load Information placard you
will find recommended tire pressure
information : for cold tires on a fully laden
vehicle. The tire pressure information is
applicable to all tires mounted at the factory.
Important notes on tire pressures
G
Warning
If the tire pressure drops repeatedly, check
the tires for punctures from foreign objects
and/or whether air is leaking from the valves
or from around the rim.
The tire temperature and pressure increase
when the vehicle is in motion. This is
dependent on the driving speed and the load.
If you wish to drive at high speeds of 100 mph
(160 km/h) or higher when this is allowed,
use the tire pressure table on the inside of the
fuel filler flap to set the correct tire pressures
when the wheels are cold. If the tire pressure
is not set correctly, this can lead to an
excessive build up of heat and a sudden loss
of pressure.
For more information, contact a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
i
Ride comfort may be affected if the tire
pressure is adjusted to the recommended
value for speeds of over 100 mph
(160 km/h).
Make sure that the tire pressure for normal
speeds is adopted again.
