WARNING
Tyres with insufficien torexcessiv etyre pres-
sure harbour the following hazards:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively or unevenly
which can severely impair tyre traction.
R the handling as well as steerin gand braking
characteristics may be severely affected.
There is arisk of an accident.
Observe the recommended tyre pressures
and check the tyre pressure of all the tyres
including the spare wheel:
R every day before starting ajourney
R when the load changes
R prior to long journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correc tthe tyre pressure. G
WARNING
If you fit unsuitable accessories ontot yre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle ontot he tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmenta
lnote
Check the tyre pressure regularly, at least
every 14 days.
You will find atable of tyre pressures for var-
ious operating conditions on the tyre pres-
sure label on the inside of your vehicle's fuel
filler flap (Y page 202).
Operation with an emergency spare
wheel: information on operation with an
emergenc yspare wheel can be found in the
general notes in the "Emergency spare wheel" section (Y page 465).
Operation with atrailer: the applicable
value for the rear tyres is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
The table of tyre pressures may also state tyre
pressures for different load conditions. These are defined in the table as different numbers
of passengers and amounts of luggage. The
actual number of seats may vary; for more
information, please refer to the vehicle's reg- istration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure information
label apply for all tyres approved for this vehi- cle. 420
