Tires and wheels
General:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only.Tire width
The tire width1 (
page 370) indicates
the nominal tire width in mm.
Aspect ratio
The aspect ratio2 (
page 370) is the
dimensional relationship between tire
section height and section width and is
expressed in percentage. The aspect ratio
is arrived at by dividing section height by
section width.
Tire code
The tire code3 (
page 370) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (
page 372).Rim diameter
The rim diameter4 (
page 370) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire load rating
The tire load rating5 (
page 370) is a
numerical code associated with the
maximum load a tire can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1 356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
page 376) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.

Tires and wheels
Tire ply material
1Plies in sidewall
2Plies under tread
This marking tells you about the type of
cord and number of plies in the sidewall
and under the tread.Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.
Warning!G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

quencePossible solution
Front Passenger Airbag
Disabled
See Operator’s ManualFront passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (page 65).
Switch off the ignition (page 40).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (page 44).
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged underneath, behind
or around the seat). Such forces may cause the system to sense that
an occupant of a lesser weight than actually present is on the front
passenger seat.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 40).

MalfunctionThe air suspension* is malfunctioning.Do not drive faster than 50 mph
(80 km/h) depending on the set
vehicle level.
Have the vehicle checked at an au-
thorized Mercedes-Benz Light
Truck Center.
Compressor
Cooling DownYou have selected a higher vehicle
level*. Due to frequent level changes
within a short period, the compressor
must first cool down.Let the compressor cool until the
message disappears.
The selected level will be set once
the compressor has cooled down.
!When the message Compressor Cooling
Down
appears in the multifunction display,
driving is still possible. Keep in mind that theride height of the vehicle is not yet reached, so
you can damage the underbody of the vehicle.The selected level will be set once the compres-
sor has cooled.

480 Practical hints
Flat tire
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.One collapsible wheel chock is includ-
ed with the vehicle tool kit
(
page 448). For information on set-
ting up the collapsible wheel chock,
see (
page 452).
Changing wheel on a level surface
Changing rear wheel on passenger side
(Example illustration)
Place the wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Changing wheel on a slight decline
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
slight decline, place the wheel chock and
another sizeable object as follows:
Changing wheel on passenger side
(Example illustration)
Always firmly set parking brake and block
wheels with wheel chocks or other sizeable
objects before raising vehicle with jack. Do
not disengage parking brake while the vehi-
cle is raised.
Make sure that the ground on which the ve-
hicle is standing and where you place the
jack is solid, level and not slippery. If neces-
sary, use a large underlay. On slippery sur-
faces, such as tiled floors, you should use a
non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing ca-
pacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
Warning!G
Only jack up the vehicle on level ground or
on slight inclines/declines. Otherwise, the
vehicle could fall off the jack and injure you
or others.
