WARNING Risk of accident caused by
repeated drop in tire pressure
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged.
Insufficient tire pressure can cause the tires
to burst.
#
Inspect the tire for signs of foreign
objects.
#
Check whether the wheel or valve has a
leak.
#
If you are unable to rectify the damage,
contact a qualified specialist workshop.
You can find information on tire pressures for
the vehicle's factory-installed tires on the follow‐
ing labels:
R
Tire and Loading Information placard on the
B‑pillar of your vehicle (/ page 522).
R
Tire pressure table on the inside of the fuel
filler flap (/ page 516).
Observe the maximum tire pressure
(/ page 528).
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.
Vehicles with a tire pressure monitoring sys‐
tem: You can also check the tire pressure using
the on-board computer.
Only correct tire pressures when the tires are
cold. Conditions for cold tires:
R
The vehicle has been parked with the tires
out of direct sunlight for at least three hours.
R
The vehicle has traveled less than 1 mile
(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 can affect
the ride comfort.

WARNING Risk of accident due to
unsuitable accessories on tire valve
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause a loss of tire
pressure. Aftermarket tire pressure monitor‐
ing systems will cause the tire valve to
remain open, depending on the design. This
can also result in a loss of tire pressure.
#
Only screw standard valve caps or valve
caps specifically approved by
Mercedes-Benz for your vehicle onto
the tire valve.
Notes on trailer operation
Always inflate the rear axle tires to the recom‐
mended tire pressures on the tire pressure table
for increased load.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap.
