& WARNING Risk of accident due to too
high a tire pressure
Tires with excessively high pressure can
burst.
In addition, they also suffer from irregular
wear, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
Avoid excessively high tire pressures.

& WARNING Risk of accident due to repea‐
ted pressure drop in the tires
The wheels, valves or tires could be damaged.
Too low a tire pressure can lead to the tires
bursting.
Examine the tires for foreign objects.
#
Check whether the tire has a puncture
#
or the valve has a leak.
If you are unable to rectify the damage,
#
contact a qualified specialist workshop.
You can find information on recommended tire
pressures for the vehicle's factory-installed tires
on the following labels:
Tire and Loading Information placard on the
R
B‑pillar of your vehicle .
Tire pressure table on the inside of the fuel
R
filler flap .
Observe the maximum tire pressure
(
page 213).
/
Use a suitable pressure gauge to check the tire
pressure. The outer appearance of a tire does not
permit any reliable conclusion about the tire
pressure.

ENVIRONMENTAL NOTE Environmental
damage due to insufficient or excessive
tire pressure
Insufficient or excessive tire pressure short‐
ens the service life of the tires.
Wheels and tires 207
Check the tire pressure regularly, but at
#
least every 14 days.
Vehicles with a tire pressure monitor: you can
also check the tire pressure using the on-board
computer.
Only correct tire pressure when the tires are
cold. Conditions for cold tires:
The vehicle has been parked with the tires out
R
of direct sunlight for at least three hours.
The vehicle has traveled less than 1 mile
R
(1.6 km).
A rise in the tire temperature of 18 °F (10 °C)
increases the tire pressure by approx. 10 kPa
(0.1 bar/1.5 psi). Take this into account when
checking the tire pressure of warm tires.
The tire pressure recommended for increased
load/speed in the tire pressure table may affect
the ride comfort.
& WARNING Risk of accident due to
unsuitable accessories on tire valves
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss.
Only screw standard valve caps or valve
#
caps specifically approved by Mercedes-
Benz for your vehicle onto the tire valve.
Notes on trailer operation
The applicable tire pressure for the tires of the
rear axle is always the recommended tire pres‐
sure for a full load.
