Parking brake
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
combustible 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 or the vehicle
drivetrain, as a result of vehicle movement,
always do the following before turning off
the engine and leaving the vehicle:

Keep right foot on brake pedal.

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

Firmly depress parking brake pedal.

Manual transmission: Move the gear-
shift lever into first or reverse gear.

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

Slowly release brake pedal.

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

Turn the SmartKey in the starter switch
to position0 and remove.

Take the SmartKey with you and lock
the vehicle when leaving, which could
endanger other road users when you en-
gage the parking brake.
Warning!G
Do not engage the parking brake while the
vehicle is in motion. Doing so can cause the
rear wheels to lock up. You could lose con-
trol of the vehicle and cause an accident. In
addition, the vehicle’s brake lights do not
light up when the parking brake is engaged,
which could endanger other road users.

Occupant safety
intensity for a maximum of 60 seconds
or until the driver’s and the front pas-
senger’s seat belt are fastened.
If you and/or your passenger release
the seat belt during driving, the seat
belt telltale < starts flashing and a
warning chime sounds as described be-
fore.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
After a vehicle standstill the warning
chime is reactivated and the seat belt
telltale < is flashing again if the ve-
hicle speed once exceeds 15 mph
(25 km/h).
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.For more information, see “Practical hints”
(
page 328).
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency
tensioning devices and belt force limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding the system deployment
threshold.

if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 58).When activated, emergency tensioning
devices remove slack from the belts. Belt
force limiters reduce the force exerted by
the seat belts on occupants during a crash.
iThe ETDs for the front seats will only acti-
vate if the respective front seat belt is fastened
(latch plate properly inserted into buckle).
The ETDs for the rear outer seats will activate
with or without the respective seat belt fastened.
Warning!G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing the emergency tensioning
device, our safety instructions must be
followed. These are available at your
authorized Mercedes-Benz Center.
