Anti-theft systems
Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey or SmartKey with KEYLESS-GO*
(Canada only) with you and lock the
vehicle. The engine can be started by
anyone with a valid SmartKey or SmartKey
with KEYLESS-GO* (Canada only) that is
left inside the vehicle.
Activating
With the SmartKey: Remove the
SmartKey from the starter switch.
With the KEYLESS-GO* (Canada
only): Turn off the engine and open the
driver’s door.
Deactivating
Switch on the ignition.
Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens:

a door

the trunk

the hood
The alarm will stay on even if the activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when

the vehicle is opened with the
mechanical key.

a door is opened from the inside.

the trunk is opened with the
emergency release button.
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(
page 67).
1Indicator lamp
iStarting the engine will also deactivate the
immobilizer.
In case the engine cannot be started (yet the
vehicle’s battery is charged), the system is not
operational. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA), or
1-800-387-0100 (in Canada).
iIf the alarm stays on for more than
30 seconds, a call to the Response Center is
initiated automatically by the Tele Aid* system
(
page 295) provided Tele Aid* service was
subscribed to and properly activated, and that
necessary mobile phone, power supply and GPS
coverage are available.

Driving and parking
SmartKey
Turning off: Turn the SmartKey in the
starter switch to position0 and remove
it.
The immobilizer is activated. KEYLESS-GO* (Canada only)
Turning off: Press the KEYLESS-GO
start/stop button to turn off the en-
gine.
With the driver’s door closed, the start-
er switch is now in position1. With the
driver’s door opened, the starter switch
is set to position0, same as SmartKey
removed from starter switch.
Releasing seat belts
Press the seat belt release button
(
page 106).
Allow the retractor to completely re-
wind the seat belt by guiding the latch
plate.
Warning!G
Do not turn off the engine before the vehicle
has come to a complete stop. With the en-
gine not running, there is no power assis-
tance for the brake and steering systems. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to brake and steer the vehicle.
iIn an emergency you can turn off the engine
while driving by pressing and holding the
KEYLESS-GO start/ stop button for approxi-
mately 3 seconds.
!Make sure the seat belt retracts fully so that
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.
