PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front air bag is deactivated.
X Turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp: R is lit : the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
R is not lit , the sensor system did not detect
a child restraint system with transponder
for the BabySmart™ air bag deactivation
system. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed.
GWARNING
Electronic devices on the front-passenger
seat can affect the function of the Baby-
Smart™ air bag deactivation system, forexample:
R Laptop
R Mobile phone
R Transponder cards such as ski passes or
access passes
The front-passenger air bag could deploy acci-
dentally or not function as intended during an accident. This poses an increased risk of
injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of thefront-passenger front air bag both before andduring the journey.
Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install the child restraint system on a
rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the information on the "Baby- Smart™ air bag deactivation system"( Y page 59).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the BabySmart™ air bag deactivation
system sensor system
R the unintentional deactivation of the front-
passenger front air bag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
