You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.Warning!
G
Vehicles with manual transmission:
Wait until the vehicle is stationary before
removing the SmartKey from the starter
switch. The vehicle cannot be steered when
the SmartKey is removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Manual transmission: Move the gear-
shift lever to neutral position (no gear is
selected).


Firmly depress parking brake pedal.


Automatic transmission*: Move the
gear selector lever to positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the SmartKey in the starter switch

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever* from
positionP, either of which could result in an
accident and/or serious injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever* not fully engaged in positionP
is dangerous. Also, when parked on an in-
cline, positionP alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, turn front wheel
towards the road curb.

Classification System (OCS)
(page 77)
As independent systems, their protective
effects work in conjunction with each
other. The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The 1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:


fails to go out after approximately
4 seconds after the engine was started


does not come on at all


comes on after the engine was started
or while driving.

traveling with you in the vehicle and

dren, see “Children in the vehicle”

Warning!
G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not deploy when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could also result in injury.
In addition, improper work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
Warning!
G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags) or side impacts (front
side impact air bags, rear side impact
air bags* and head protection window cur-
tain air bags). However, no system available
today can totally eliminate injuries and fatal-
ities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
