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 raised (only vehicles with
tow-away alarm)

the vehicle is opened with the
mechanical key

a door is opened from the inside
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(
page 78).1Indicator lamp
Arming: Lock your vehicle with the
SmartKey or KEYLESS-GO*.
The turn signal lamps flash three times
to indicate that the vehicle is locked.
The indicator lamp1 flashes to indi-
cate that the alarm system is armed.
iStarting the engine will also deactivate the
immobilizer.
In case the engine cannot be started (yet the ve-
hicle’s battery is charged), the system is not op-
erational. 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 ini-
tiated automatically by the Tele Aid system
(
page 482) provided Tele Aid service was sub-
scribed to and properly activated, and that nec-
essary mobile phone, power supply and GPS
coverage are available.

Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key.

portion of the two SmartKeys are of differ-
ent color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
