GAWR (Gross AxleW
eight Rating)
The GAWR is the maximu mgross axle weight
rating. The actua lloa donana xle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicl eidentification plate on the B-pillar on
the driver's side. Speed rating
The spee drating is part of the tire
identification. It specifies the spee drange for
which the tire is approved. GVW (Gross Vehicle Weight)
The gross vehicl eweight includes the weight
of the vehicl eincluding fuel ,tools, the spare
wheel, accessories installed, occupants,
luggage and the drawbar noseweight, if
applicable.T he gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification plate
on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of afully loaded vehicle (the weight of
the vehicle including all accessories,
occupants, fuel, luggage and the drawbar
noseweight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side. Maximum loaded vehicle weight
The maximum weight is the sum of:
R the curb weight of the vehicle
R the weight of the accessories
R the load limit
R the weight of the factory installed optional
equipment Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa
corresponds to 1psi. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of 1bar. Load index
In addition to th eload-bearing index ,the load
index may also be imprinted on th esidewall
of th etire. This specifie sthe load-bearing
capacity more precisely. Curb weight
The weight of avehicle with standard
equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning system and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage. Maximum load rating
The maximum load rating in kilograms or
pounds is the maximum weight for which a
tire is approved. Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire. Maximum load on one tire

WARNING
Interchangin gthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is arisk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with atire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed at aqualified
specialist workshop.
Always pay attention to the instructions and
safety notes when changing awheel
(Y page 336).
The wear pattern sonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Frontt ires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotatet he wheels according to the intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles
(5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of wheel rotation.
Clean the contac tsurface softhe wheel and
the brake disc thoroughly every time awheel
is rotated. Check the tire pressure and, if
necessary, restart the tire pressure loss
warning system or the tire pressure monitor. Direction of rotation
Tires with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
maintained.
An arrow on the sidewall of the tire indicates
its correct direction of rotation. Storing wheels
Storew heels that are not being used in acool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel. Cleaningt

WARNING
The water jet from acircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately. 336
