Problems with the Occupant Classification System (OCS)
Be sure to observe the notes on "System self-test" (Ypage 52).
ProblemPossible causes/consequences andMSolutions
The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son of a stature corre-
sponding to that of an
adult.The classification of the person on the front-passenger seat is incor-
rect.
XMake sure the conditions for a correct classification of the person
on the front-passenger seat are met (Ypage 49).
XIf the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
XHave OCS checked as soon as possible at an authorized Mercedes- Benz Center.
The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seat
is:
Runoccupied
Roccupied with the
weight of a child up to
twelve months old in a
child restraint system
OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and the child
seat.
XMake sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as flat as possible
against the backrest of the front-passenger seat. If necessary,
adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
XMake sure that no objects are applying additional weight onto the
seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install a child restraint system on the front-passenger seat. It is recom-
mended that you install the child restraint system on a suitable rear
seat.
XHave OCS checked as soon as possible at an authorized Mercedes-Benz Center.
Roll bar
GDANGER
If the roll bar has developed a malfunction, it
may not function, e.g. in the event of an acci- dent. The roll bars may then not protect the
vehicle occupants as intended. This poses an
increased risk of injury or even fatal injury.
Have roll bars checked immediately at a quali-
fied specialist workshop.
GWARNING
Risk of injury if the roll bar is triggered.
Ensure that the movement area of the roll bars
behind the rear head restraints is kept clear.

Important safety notes
GWAR NING
If you switch off the ignition while driving,
safety-relevant functions are only available
wit hlimit ations, or not at all.This could affect,
for example, the power steering and the brake
boosting effect. You willrequire cons iderably
more effort to steer and brake. There isa risk
of an acc ident.
Do not switch off the ignition while driving.
GWARNING
If you operate mob ilecommunication equip-
ment while driv ing, youwill be dist racted from
traff icconditions. You could also lose control
of the veh icle. There isa risk of an acc ident.
Only operate this equipment when the vehicle
isstationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while
driv ing a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
dist ance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not needed.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.

Vehicle tool kit
General notes
Apart from certain country-specific variations,
the vehicles are not equipped with a tire-change
tool kit. If your vehicle is equipped with a tire-
change tool kit, it is located in the stowage well
under the trunk floor. Some tools for changing a
wheel are specific to the vehicle. For more infor-
mation on which tire changing tools are required
and approved to perform a wheel change on
your vehicle, consult a qualified specialist work- shop.
Necessary tire-changing tools can include, for
example:
RJack
RWheel chock
RLug wrench
RRatchet wrench
RAlignment bolt

Your vehicle may be equipped with:
Rtires with run-flat characteristics
(MOExtended tires) (Ypage 289)
Vehicle preparation is not necessary on vehi-
cles with MOExtended tires
Ra TIREFIT kit (Ypage 288)
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit may be obtained from a qualified specialist workshop.

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 315).
MOExtended tires may only be used in conjunc-
tion with an active tire pressure monitor.
If a pressure loss warning message appears
in the multifunction display:
Robserve the instructions in the display mes-
sages (Ypage 226).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partially laden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon:
RVehicle speed
RRoad condition
ROutside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed a maximum permissible
speed of 50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires:
Rsize
Rthe type and
Rthe "MOExtended" mark
If a tire has gone flat and cannot be replaced
with a MOExtended tire, a standard tire may be
used as a tempora ry mea
sure. Make sure that you use the proper size and type (summer or
winter tires).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit may be obtained from
a qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tempera-
tures down to Ò4 ‡ (Ò20 †).
Flat tire289
Breakdown assistance
Z

GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tire properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
RImmediately change out of clothing which
has come into contact with tire sealant.
RIf an allergic reaction occurs, seek medical
attention immediately.
!Residue from the tire sealant may come out
of the filler hose after use. This could cause
stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
!Do not operate the tire inflation compressor
for longer than eight minutes at a time without
a break. It may otherwise overheat.
The tire inflation compressor can be operated
again once it has cooled down.
Comply with the manufacturer’s safety instruc-
tions on the sticker on the tire inflation com-
pressor.
Using the TIREFIT kit
XDo not remove any foreign objects which have
penetrated the tire, e.g. screws or nails.
XRemove the tire sealant bottle, the accompa-
nying TIREFIT sticker and the tire inflation
compressor from the stowage well under-
neath the trunk floor (
Ypage 288).
XAffix part :of the TIREFIT sticker to the
instrument cluster within the driver's field of
vision.
XAffix part ;of the TIREFIT sticker near the
valve on the wheel with the defective tire.

the vehicle (Ypage 260).
XTurn the SmartKey to position 1in the ignition
lock (Ypage 124).
XPress on and off switch =on the tire inflation
compressor to position I.
The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of five minutes. The tire should then
have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tire pres-
sure reached" (
Ypage 291).
If a tire pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
Ypage 291).
If tire sealant has escaped, clean it off affected
areas as quickly as possible. Use plain water if
possible. If your clothes are soiled with tire sealant, have
them cleaned with perchloroethylene at a dry
cleaner as soon as possible.
Tire pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
Tire sealant may escape when the filler hose is
unscrewed.
XVery slowly drive forwards or reverse approx- imately 30 ft (10 m).
XPump up the tire again.
After a maximum of five minutes the tire pres-
sure must be at least 180 kPa (1.8 bar/
26 psi).
GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
GWARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h).
The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driver's
field of vision.
