Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone:

opens a door


opens the liftgate


opens 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


someone attempts to raise the vehicle


unlocking and opening the driver’s
door with the mechanical keyArming the alarm system
The alarm system is armed after locking
the vehicle with the remote control. The
turn signal lamps flash three times to indi-
cate that the alarm system is activated. A
red indicator lamp in the center console
will flash after approximately 10 seconds
when the alarm system is completely
armed (
page 27).
iIn case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Light
Truck 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 174) provid-
ed Tele Aid service was subscribed to
and properly activated, and that neces-
sary cellular service and GPS coverage
are available.

Warning!
G
Before programming the integrated remote
control to a garage door opener or gate op-
erator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage.When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks safe-
ty stop and reverse features as required by
U.S. federal safety standards (this includes
any garage door opener model manufac-
tured before April 1, 1982). A garage door
that cannot detect an object - signaling the
door to stop and reverse - does not meet
current U.S. federal safety standards.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience diffi-
culties with programming the transmit-
ter, contact an authorized
Mercedes-Benz Light Truck Center, or
call Mercedes-Benz Customer Assis-
tance Center (in the USA only) at
1-800-FOR-MERCedes, or Customer
Service (in Canada) at
1-800-387-0100.

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at the intervals specified in the Mainte-
nance Booklet and as required by the
maintenance service indicator. Contact
an authorized Mercedes-Benz Light
Truck Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
