sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if only parts which are relatively easilyd eformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as aresult.
If the restraint system control unit detects aside
impact or if the vehicle rolls over, the applicable
componentsoft he restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
RSide impact air bags on the side where the
impact takes place, independently of the
EmergencyT ensioning Device and the use of
the seat belt on the driver's seat and outer
seats in the second row
The side impact air bag on the front-
passenger side deploysu nder the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
RWindow curtain air bag on the side of impact, independently of the use of the seat belt and
independently of whether the front-
passenger seat is occupied
REmergencyT ensioning Devices, if the system
determines that deployment can offer addi-
tional protection in this situation
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the seat
belt
iNot all air bags are deployed in an accident.
The different air bag systems work independ- ently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
RFrontal collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel supply
is cut off
Rvehicles with mbrace: automatic emergency
call
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
ac hild restraint system on arear seat. Children
are generally better protected there.
If ac hild younger than twelve years old and
under 5ft(1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in achild restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
Rbe sure to observe the instructions and safety notes on the "Occupant classification system
(OCS)" (
Ypage 47)

Safety

You must make sure that fuel does not comeint oc ontac twith your skin ,eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors.K eep fuel away from children.
If you or others com eintoc ontac twith fuel,
observet he following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes int ocontac twith your eyes,
immediately rinse the mthoroughly with
clean water. Seek medical assistanc ewith-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induc evomit-
ing.
RImmediately change out of clothing which
has com eintoc ontac twith fuel.
GWARNING
Electrostatic buildup can create sparksa nd
ignit efuel vapors.T here isarisk of fire and
explosion.
Always touc hthe vehicle body beforeo pening
the fuel filler flap or touching the fuel pump
nozzle. An yexisting electrostatic buildup is
thereby discharged.
!Do not use diesel to refuel vehicles with a
gasolinee ngine. Do not switc honthe ignition
if you accidentally refuel with the wrongf uel.
Otherwise, the fuel will enter the fuel system. Even small amount softhe wrongf uel could
result in damage to the fuel syste mand the
engine. Notify aqualified specialis tworkshop
and have the fuel tan kand fuel lines drained
completely.
!Overfilling the fuel tan kcould damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use afilter when adding fuel from afuel can.
The fuel lines and/or the fuel injection system
could otherwise be blocked by particles from
the fuel can. Do not get int
othe vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.

General notes
You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
You should regularl ycheck the pressure of the
emergency spare wheel, particularly priort o
long trips, and correct the pressure as neces-
sary (
Ypag e290). The valu eonthe wheel is
valid.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for you rvehicle.
These tires have been speciall yadapted for
use with the control systems, such as ABS or
ESP
®,a nd are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-fla tcharacteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be use donwheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehiclen oise
emissions or fuel consumption, may other-
wis ebea dversely affected .Inaddition, when
driving with aload, tire dimension variations
coul dcaus ethe tires to come into contact
with the bodywork and axle components. This
coul dresult in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Informatio nontires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
!Retreaded tires are neither tested nor rec-
ommendedbyM ercedes-Benz, since previ-
ous damage cannot alway sbedetected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicles afety if retreaded
tires are mounted .Donot mount use dtires if
you have no information abo ut thei
r previous
usage. The recommendedp
ressures for various oper-
ating conditions can be found:
Ron the Tire and Loading Informatio nplacard
on the B-pillar on the driver's side
Rin the tire pressure tabl einthe fuel filler flap
Observe the notes on recommendedt ire pres-
sure sunder various operating conditions
(
Ypag e290).
Check tire pressures regularly,a nd only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicled ocument wallet.
Notes on the vehiclee quipment–alway sequip
the vehicle:
Rwith tires of the same size on agivena xle (left
and right)
Rwith the same type of tire (summer tires,
MOExtended tires, winter tires)
Exception: it is permissible to instal ladiffer-
ent type or make in the event of aflat tire.
Observe the "MOExtended tires (tires with
run-fla tcharacteristics" section (
Ypag e271).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory.I t
is therefore recommendedt hat you additionally
equip you rvehiclew ithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit may be obtained from
