Problems with the Occupant Classification System (OCS)
Be sure to observe the notes on "System self-test"(Ypage 51).
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 oraper-
son of astature corre-
sponding to that of an
adult.The classification of the person on the front-passenger seat is incor-
rect.
XMake sure the conditionsf orac orrect 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 achild up to
twelve months old in a
child restraint system
OCS is malfunctioning.
XMake sure there is nothin gbetween 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 aload to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
XMake sure that no object sare 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 ac hild restraint system on the front-passenger seat. It is recom-
mended that you install the child restraint system on asuitable rear
seat.
XHave OCS checked as soon as possible at an authorized Mercedes- Benz Center.

MOExtended tires( tires with run-flat
properties)
General notes
With MOExtended tire s(tires with run fla tchar-
acteristics) ,you can continu etodrive your vehi-
cle eve nifthere is atotal loss of pressure in one
or more tires. The affected tire mus tnot show
any clearl yvisible damage.
You can recognize MOExtended tire sbythe
MOExtended marking which appears on the
sidewal lofthe tire .You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 330).
MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warnin gmessage appears
in the multifunctio ndisplay:
Robserve the instructions in the display mes-
sages (Ypage 241).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mod eis
approximately 50 miles (80 km )whent he vehi-
cle is partiall ylad en. Whe nthe vehicl eisfully
laden it is approximately 19 miles (30 km). In addition to the vehicl
eload, the driving dis-
tance possible depends upon:
Rvehicl espeed
Rroa dcondition
Routsid etemperature
The driving distance possible in run-flat mode
may be reduce dbyextremedriving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mod

unted from the moment the tire pressure loss
warning appears in the multifunction display.
You mus tnot excee damaximum speed of
50 mph (80 km/h).
Whe nreplacing one or al ltires, please observe
the following specifications for your vehicle's
tires:

Vehicles equipped with MOExtended tire sare
not equipped with aTIREFIT kit at the factory. It
is therefore recommended that yo uaddit ionally

XLet thetirei nflation compressor run for a
maximum of te nminutes. The tire should then

(2. 0b ar/2 9psi).
If ap ressur eof200 kPa( 2.0b ar/29 psi) has
been attained after fiv eminutes, see "Tir epres-

Ypage 304).
If at irep ressur eof200 kPa(2.0 bar/29 psi) has
not beena ttained after five minutes ,see "Tire
pressure not reached" (
Ypag e303).
If tire sealant has escaped, clea nitoff affected
area sasq uickly as possible. Use plain water i
f
possible.
If you rclothes are soiled with tire sealant, have
them cleaned with perchloroethylene at adry
cleaner as soon as possible.
Tire pressure not reached
If at ire pressure of 200 kPa (2.0 bar/29 psi) has
not beena ttained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
Note that tire sealant may escap ewheny ou
unscrew the filler hose.
XVery slowly drive forwards or reverse approx- imately 30 ft (10 m).
XPump up the tire again.
After amaximu moften minutes ,the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 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 atire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
