PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front air
bag is deactivated.
XTurn 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:
Ris lit : the front-passenger front air bag is
deactivated. It will then not be deployed in the
event of an accident.
Ris 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, for
example:
RLaptop
RMobile phone
RTransponder 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 the
front-passenger front air bag both before and
during 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 children 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"
(
Ypage 50).
You can thus avoid the risks that could arise as
a result of:
Ra child restraint system that is not detected
by the BabySmart™ air bag deactivation sys-
tem sensor system
Rthe unintentional deactivation of the front-
passenger front air bag
Rthe unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facing child restraint system
If it is absolutely necessary to install a rearward-
facing child restraint system on the front-
passenger seat, always make sure that the
front-passenger front air bag is deactivated.
Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit (
Ypage 35) is the front-
passenger front air bag deactivated.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.
Forward-facing child restraint system
If it is absolutely necessary to install a forward-
facing child restraint system on the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible

ProblemPossible causes/consequences andMSolutions
The PASSENGER AIR
BAG OFF indicator lamp
on the center console is
lit.A special Mercedes-Benz child restraint system with a transponder for
the BabySmart™ air bag deactivation system has been installed on the
front-passenger seat. The front-passenger air bag has therefore been
deactivated as desired.
GWARNING
There is no child restraint system installed on the front-passenger
seat. The BabySmart™ air bag deactivation system is malfunctioning,
for example due to electronic devices on the front-passenger seat.
There is a risk of injury.
XRemove electronic equipment from the front-passenger seat, for
example:
RLaptop
RMobile phone
RCard with a transponder, such as a ski pass or access pass
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.

Driving tips
General driving tips
Important safety notes
GWARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's
concentration must always be directed pri-
marily at road traffic. For your own safety and
that of others, we recommend that you stop
the vehicle at a safe place and in accordance
with the traffic conditions before making or
accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate COMAND (Cockpit Managementand Data System) in compliance with all legal
requirements and when the road, weather and
traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance
of 44 ft (approximately 14 m)a second when
it is traveling at only 30 mph (approximately
50 km/h).
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
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 carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work performed at the
service intervals specified in the Maintenance
Booklet or indicated by the service interval
indicator.
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
