Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt. The
air bag provide sa dditional protection in appli-
cable accident situations.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another ( Y
page 50).
However, no system available today can com-
pletel ye liminate injuries and fatalities.
It is also not possible to rule out ar isk of injury
cause dbyana ir bag due to the high speed at
which the air bag must be deployed.
Important safety notes
G WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed .T his poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants: R
have fastened their seat belts correctly,
including pregnant women R
are sitting correctly and maintain the great-
est possible distance to the air bags R
follow the following instructions
Alway sm ake sure that there are no objects
between the air bag and the vehicle's occu-
pants. R
Adjust the seats properl yb efore beginning
you rj ourney. Alway sm ake sure that the seat
is in an almos tu pright position. The center of the head restraint must support the head at
abou te ye level. R
Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely. R
Only hold the steering wheel on the outside.
This allows the air bag to be full yd eployed.R
Alway sl ea na gainst the backrest whil ed riv-
ing. Do not lea nf orward or lea na gainst the
door or side window .Y ou may otherwise be in
the deployment area of the air bags. R
Alway sk eep you rf eet in the footwell in front
of the seat. Do not put you rf eet on the dash-
board ,f or example .Y our feet may otherwise
be in the deployment area of the air bag. R
For this reason, always secure persons less
than 5f t( 1.5 0m )t all in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If ac hil dist raveling in your vehicle, also

Make sure when adjusting as eat that no one
has any body parts in the sweep of the seat.
G WARNING
If the driver's seat is not engaged, it could
move forwards as far as the next catc hd uring
movemen ts uch as braking or abrupt changes
of direction .Asar esult, you would be pushed
against your seat belt by the unsecured driv-
er's seat.
This could cause you to lose control of the

Speed rating The speed rating is part of the tire identification.
It specifies the speed range for which the tire is
approved.
GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of
the vehicle including fuel, tools, the spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight, if applicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight rating GVWR as specified on the vehi-
cle 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 af ully 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.
Maximu ml oaded vehicle weightThe 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 corre-
sponds to 1p si. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewal lo f
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of av ehicle with standard equipment
including the maximum capacity of fuel, oil and
coolant. It also includes the air-conditioning sys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage. Maximu ml oad ratingThe maximum load rating is the maximum per-
missible weight in kilograms or lbs for which a
tire is approved.
Maximu mp ermissible tire pressureMaximum permissible tire pressure for one tire.
Maximu ml oad on one tireMaximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (pounds per squar ei nch)As tandard unit of measure for tire pressure.
Aspect ratio Relationship between tire height and tire width
in percent.
Tire pressure This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and R
if the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.All about wheel sa nd tires 279

must be positioned vertically, directly under
the jacking point of the vehicle.
! Only position the jack at the appropriate
jacking point of the vehicle. Otherwise, you
could damage the vehicle.
Observe the following when raising the vehicle: R
To rais et he vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicl er aised.R
The jack is designed only to rais ea nd hold the
vehicl ef or as hort time while aw hee lisb eing
changed. It must not be used for performing
maintenance work under the vehicle. R
Avoid changing the whee lonu phill and down-
hill slopes. R
Before raising the vehicle, secure it from roll-
ing awa ybya pplying the parking brake and
inserting whee lc hocks. Do not disengage the
parking brake whil et he vehicl eisr aised.R
The jack must be placed on af irm, flat and
non-slip surface. On al oose surface, al arge,
flat, load-bearing underlay must be used .Ona
slippery surface, an on-slip underlay must be
used ,e .g. rubber mats.R
Do not use wooden blocks or similar objects
as aj ack underlay .O therwise, the jack wil ln ot
be abl etoa chieve its load-bearing capacity
due to the restricted height. R
Make sure that the distance betwee nt he
underside of the tires and the ground does not
exceed 1.2 in (3 cm). R
Never place you rh ands and feet under the
raised vehicle. R
Do not lie under the vehicle. R
Do not start the engine when the vehicl ei s
raised. R
Do not open or close ad oor or the trunk lid
when the vehicl eisr aised.R
Make sure that no persons are present in the
vehicl ew hen the vehicl eisr aised. X
Using lug wrench C ,l oose nt he bolts on the
whee ly ou wish to change by abou to ne full
turn. Do not unscrew the bolts completely.
The jacking points are located just behind the
front whee lh ousings and just in front of the rear
whee lh ousings (arrows).
