The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey or SmartKey with KEYLESS-GO*

that is left inside the vehicle.

switch.

Press the start/stop button on the gear
selector lever once.

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 lid
the hood
a storage compartment in the rear
the glove box
the storage compartment under the
armrest
The alarm will stay on, even if the activat-
ing element (a door, for example) is imme-
diately closed.
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

437 Practical hints
Fuses
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
trunk with the vehicle tool kit
(
page 400).
The electrical fuses are located in different
fuse boxes:
on the driver’s side of the engine com-
partment (
page 438)
on the passenger side of the engine
compartment (
page 438)
under passenger-side rear storage
compartment (
page 439)
in the trunk (page 439)Before replacing fuses:
Apply the parking brake (page 63).
Make sure the gear selector lever is set
to position P (
page 172).
Turn off all electrical consumers.
Turn off the engine (page 64).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*: Open
the driver’s door.
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Center
iA blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
iIn case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-Benz
Center.
