Maximum tire pressures
:Maximum permitted tire pressure (example)
Never exceed the maximum permissible tire
inflation pressure. When adjusting the tire pres-
sures always observe the recommended tire
pressure for your vehicle (
Ypage 246).
iThe actual values for tires are specific to
each vehicle and may deviate from the values in the illustration.
Tire valve
GWARNING
Tire valve that are not approved for your vehi-
cle by the distributor named on the inside
cover page may result in a loss of tire pres-
sure. This may affect road safety. There is a
risk of an accident.
Only use tire valve that are approved for your
vehicle by the distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
!Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
Only for vehicles without a tire pressure moni-
tor:
For safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that have
been tested for use on your vehicle.
Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceed as follows:
XRemove the valve cap of the tire you wish to
check.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with the
recommended value on the loading informa-
tion table or the tire pressure table
(
Ypage 246).
XIf the tire pressure is too low, increase it to the
recommended value.
XIf the tire pressure is too high, release air by
pressing down the metal pin in the valve. Use
the tip of a pen, for example. Then, check the
tire pressure again using the tire pressure
gauge.
XScrew the valve cap onto the valve.
XRepeat the steps for the other tires.
Tire pressure monitor
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire pressure
label on the inside of the fuel filler flap. If your
vehicle has tires of a different size than the
size indicated on the Tire and Loading Infor-
mation placard or the tire pressure label, you
should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale illuminates,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
