zrecommends that you use a
Mercedes-Ben zService Centre for this. Restraint system warning lamp
The restraint systems functions are checked
after the ignition is switched on and at regular
intervals when the engine is running. This allows
malfunctions to be quickly identified.
The 6 restraint system warning lamp in the
instrumentc luster lights up when the ignition is
switched on. It goes out no later than afew sec-
onds after the vehicle is started. The compo-
nentsoft he restraint system are in operational

Am alfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not switch off after afew seconds when
the engine is running
R lights up again when the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensionersora irbags, for example.
There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at aqualified specialist
workshop. PASSENGER AIR BAG indicator lamp PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabledore nabled; see the following
points. You must make sure of this both before
and during ajourney.
R Children in arearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 47) and on "Children in the
vehicle" (Y page 55).
R Children in aforward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabledore nabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva-
tion system" (Y page 47) and on "Children in
the vehicle" (Y page 55).
R All other persons: the PASSENGER AIR BAG
ON indicator lamp must be lit. The front-
passenger front airbag is enabled. Depending on the build of the person on the front-

OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In
this case, the front-passenger seat should not be used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 47) as well as
on "Seat belts" (Y page 41) and "Airbags"

Occupant safetySafety

If childre
nare travelling in the vehicle ,besure to
observe the notes on "Childrenint he Vehicle"
(Y page 55).
If the automatic co-driver's front airbag deacti-
vation system is malfunctioning, the red 6
restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG OFF indi-
cator lamp light up simultaneously. The co-driv-
er's front airbag is disabled in this case and does not deploy during an accident. Have the system
checked as soon as possible by qualifiedt ech-
nicians. Consul taMercedes-Benz Service

tem.
System self-test G
DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lampsdo
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front airbag might be triggered
unintentionally or might not be triggered at all in the event of an accident with high deceler-
ation. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used.Don ot installachild restraint system

matic front-passenger front airbag deactiva-
tion system checked and repaired immedi-
ately at aqualifieds pecialist workshop. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp remains lit after the system self-test, the
front-passenger front airbag is disabled.Itw ill
not be deployed in the event of an accident. In
this case, the front-passenger front airbag cannot perform its intended protective func-
tion, e.g. when
aperson is seated in the front-
passenger seat.
That person could,f or example,come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board.T his poses an increased risk of injury or
even fatal injury.

tion of the automatic front-passenger front
airbag deactivation system. This could result
in the front-passenger front airbag not func-
tioning as intended during an accident. This
poses an increased risk of injury or even fatal injury.
Do not place any objects betwee nthe seat
surface and the child restraint system. The
entire base of the child restraint system must always rest on the seat cushio nofthe front-

All vehicles except vehicles with alithium-
ion battery: if the indicator/warning lamps in
the instrument cluster do not light up at low
temperatures, it is very likely that the dis-
charged battery has frozen .Inthis case you may
neither jump-start the vehicle nor charge the
battery. The service life of abattery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at aqualified specialist workshop. Vehicles with
alithium-ion battery: at low
temperatures, do not charge abattery which has
been removed using abattery charger. Allow the
battery to warm up gently first, if necessary.
Otherwise, the service life can be shortened and the starting characteristics impaired, especially
at low temperatures. 344
