on tires are specific to each vehicle and
may vary from data shown in above
illustration.
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
Tire width : indicates the nominal tire width
in millimeters. Aspect ratio
Aspect ratio
; 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
Tire code = indicates the tire construction
type. The “R” stands for radial tire type. Letter
“D” means diagonal 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” (Y page 203).
Rim diameter
Rim diameter ? is the diameter of the bead
seat, not the diameter of the rim edge. The
rim diameter is indicated in inches (in).
Load index G
Warning!
The tire load rating must always be at least
half of the GAWR of your vehicle. Otherwise,
tire failure may be the result which may cause
an accident and/or serious injury to you or
others.
Always replace rims and tires with the same
designation, manufacturer and type as shown
on the original part. G
Warning!
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Load index A is a numerical code associated
with the maximum load a tire can support. 202

The
front 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.
X Stop the vehicle in a safe location as soon as possible.
X Engage the parking brake.
X Switch off the ignition.
X Have the front passenger vacate the seat and exit the
vehicle.
X Adjust the seat height to a higher position (Y page 78).
X Make sure 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.
X Keep the seat unoccupied, close the front passenger door
and switch on the ignition.
Monitor the 04 indicator lamp in the center
console (Y page 44) and the multifunction display in the
instrument cluster
(Y page 28) for the following:
With the seat unoccupied and the ignition switched on,
R the 04 indicator lamp in the center console
should illuminate and remain illuminated, indicating that
the OCS (Y page 41) has deactivated the front passenger
front air bag.
R the message Front Passenger Airbag Enabled See
Operator’s Manual or the message Front Passenger
Airbag Disabled See Operator’s Manual should not
appear in the multifunction display at any time the seat is
unoccupied. Wait at least 60 seconds for the system to
complete the necessary check cycles and to make sure
neither message appears in the multifunction display.
If above conditions are met, you can occupy the front
passenger seat again. Depending on the front passenger
classification sensed by the OCS, the 04
indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working
properly. Have the system checked at an authorized
Mercedes-Benz Center as soon as possible. 232

with the jack. Do not disengage the parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, 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
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
X Prevent the vehicle from rolling away by
blocking wheels with wheel chocks or other
sizeable objects.
When your vehicle is equipped with a wheel
chock, it is included with the vehicle tool kit
(Y page 224). For information on setting up
the collapsible wheel chock, see
(Y page 225).
When changing a wheel on a level surface:
X Place a wheel chock or other sizeable
object in front of and another wheel chock
or other sizeable object behind the wheel
that is diagonally opposite to the wheel
being changed.
Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a hill:
X Place wheel chocks or other sizeable
objects on the downhill side in front of both
wheels on the side opposite to the side on
which the wheel is to be changed. G
Warning!
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. X
On the wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench :).
The jack take-up brackets are located directly
behind the front wheel housings and in front
of the rear wheel housings. G
Warning!
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets. Make
sure the jack arm is fully seated in the jack
take-up bracket.
If you do not position the jack correctly in the
jack take-up bracket, the vehicle can fall off
the jack and seriously or fatally injure you or
others.
! Do not position the jack on the body of
the vehicle, as this may cause damage to
the vehicle. Flat tire
