WARNING
If the tire pressure drops repeatedly, the wheel, valve or tire may be damaged. Tire pressure that is too low may result in a tire blow-out. There is a risk of an accident.
• Check the tire for foreign objects.
• Check whether the wheel is losing air or the valve is leaking.
If you are unable to rectify the damage, contact a qualified specialist workshop.
WARNING
If you fit unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. Due to their design, retrofitted tire pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There is a risk of an accident.
Only screw the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle onto the tire valve.
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. On vehicles equipped with the electronic tire pressure monitoring system, the tire pressure can be checked using the on-board computer.
The tire temperature and pressure increase when the vehicle is in motion. This is dependent on the driving speed and the load.
Therefore, you should only correct tire pressures when the tires are cold.
The tires are cold:
• if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
• if the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 (10
), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when
checking the pressure of warm tires. 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.
Observe the recommended tire pressures for
cold tires:
• on the Tire and Loading Information placard
on the B-pillar on the driver's side
• in the tire pressure table on the inside of
the fuel filler flap
• printed in yellow on the rim of the
emergency/collapsible spare wheel
(depending on vehicle equipment)
