Tire pressure
230
The load conditions "partially laden" and "fully
laden" are defined in the table for different
numbers of occupants and amounts of lug-
gage. The actual number of seats may differ.
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18. Rim diameter is part of the tire size and
can be found on the tire sidewall
( page 241).
Y
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to
the higher values:
if you want to drive with an increased load
R
and/or
if you want to drive at higher road speeds
R
The tire pressures for increased loads and/or
higher road speeds, shown in the tire pres-
sure table, may have a negative effect on driv-
ing comfort.
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 spe-
cialist workshop.
Important notes on tire pressure
G
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.
R
Check whether the wheel is losing air or the
R
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
G
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 pres-
sure 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 monitor, the tire
pressure can be checked in the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
