Parking and locking
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.Warning!
G
Vehicles with Airmatic: If you have selected
the Comfort suspension tuning
(page 265), the vehicle lowers slightly
when it is locked. You should therefore
make sure that no one is standing near the
wheel arches or lying underneath the vehi-
cle when it is being locked. Otherwise, per-
sonal injury could result.
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, or
damage to the vehicle drivetrain, as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the gear selector lever to
positionP.


Slowly release brake pedal.


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


Turn the SmartKey to starter switch
position0 and remove, or press
start / stop button (vehicles with
KEYLESS-GO*).


Take the SmartKey or the SmartKey with
KEYLESS-GO* and lock vehicle when
leaving.
!
Vehicles with Airmatic: If you have selected
the Comfort suspension tuning (
page 265),
the vehicle lowers slightly when you lock it within
approximately 60 seconds after switching off the
engine. When parking, make sure that your vehi-
cle cannot come into contact with other objects,
such as a curb, while lowering. Your vehicle
could otherwise be damaged.

the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limited Warranty.
Damaged seat belts must be replaced. Contact
an authorized Mercedes-Benz Center.

68 Safety and SecurityOccupant safetyIn this section you will learn the most
important facts about the restraint sys-
tems of the vehicle.
The restraint systems are

Seat belts (
page 82)


Child restraints (
page 89)


Lower Anchors and Tethers for
CHildren (LATCH) (
page 94)
Additional protection is provided by


Supplemental Restraint System (SRS)
with

Air bags (
page 70)


Air bag control unit (with crash
sensors)


Emergency Tensioning Device
(ETD) for seat belts (
page 85)


Active head restraints (
page 87)


Preventive occupant safety
(PRE-SAFE
®) (page 86)Air bag system components with

tor lamp (

USA only:
Front passenger seat with Occupant
Classification System (OCS)
(page 75)


Canada only:

BabySmart
TM air bag deactivation sys-
tem (
page 81)
As independent systems, their protective
functions 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
1
indicator lamp in the instrument
cluster lights up 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
1
indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1
indicator 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

eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in

69 Safety and Security
Occupant safety
Warning!
G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with in-
terconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the de-
celeration threshold for air bag deployment
is exceeded. Therefore, never modify the re-
straint systems. Do not tamper with elec-
tronic components or their software.
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 be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in
injury.
In addition, improper repair 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.
