Locking and unlocking with remote control
Unlocking:
Press transmit button Œ. All turn signal lamps blink
once to indicate that the vehicle is unlocked.
The remote control can be programmed for two kinds of
unlocking modes (see below):
Selective unlocking mode –
Press transmit button Œ once to unlock driver’s door
and fuel filler flap.
Press transmit button Πtwice to unlock all doors,
fuel filler flap, and trunk.
Global unlocking mode –
Press transmit button Πonce to unlock all doors,
fuel filler flap, and trunk.
Notes:
If the trunk was previously locked separately, it will
remain locked, see page 53.
The presently active unlocking mode (selective or
global) can only be determined by unlocking the vehicle
with the remote control (see below for changing mode).If within 40 seconds of unlocking with the remote
control, neither door nor trunk is opened, the electronic
key is not inserted in the starter switch, or the central
locking switch is not activated, the vehicle will
automatically lock.
Locking:
Press transmit button ‹ once. All turn signal lamps
blink three times to indicate that the vehicle is locked. If
they do not blink three times, a door or trunk is not
properly closed.
Note:
If the vehicle cannot be locked or unlocked by pressing
the transmit button, then it may be necessary to change
the batteries in the electronic main key (if ok, battery
check lamp in electronic main key will light briefly
when pressing transmit button) or to synchronize the
remote control, see pages 363 and 365.

KEYLESS-GO
Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•The driver should carry the KEYLESS-GO-card with
him / her.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).
•To lock or unlock the vehicle, the card must be
recognized by the system as being located outside
the vehicle. The card must be in close proximity to a
door or the trunk lid (approx. 3 ft. [1 m]). To activate
the start / stop button function, the KEYLESS-GO-
card must be recognized by the system as being
located inside the vehicle.
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or a briefcase)
and can no longer be recognized by the system, the
vehicle cannot be locked or the engine started via
the KEYLESS-GO-system.•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 195), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly in the multifunction display,
seepage322.
Find the card or change its present location (e.g.
place it on the front passenger seat or insert it in
shirt pocket).
•If the message “CHIP - CARD – NOT RECOGNIZED”
is ignored for an extended of time (approx.
15 minutes), the engine could stop by itself during a
vehicle stop (e.g. traffic light). The vehicle can then
no longer be centrally locked or the engine
restarted. You must first find the card or change its
present location (e.g. place it on the front passenger
seat or insert it in shirt pocket). Start the engine
again. See page 228.
•Do not forget, the engine can be started by anyone
with a KEYLESS-GO-card that is left inside the
vehicle. Leaving the chip-card behind when exiting
and locking the vehicle, the message “CHIP-CARD –
STILL IN VEHICLE” appears in the multifunction
display, see page 322.

Safety guidelines for the seat belt, emergency
tensioning retractor and airbag
If you believe that, even with the use of these
guidelines, it would be safer for your rear seat
occupants to have both rear door mounted side
airbags deactivated, then deactivation can be
accomplished upon your written election to do so at
your authorized Mercedes-Benz Center at an
additional cost. Please contact your local
authorized Mercedes-Benz Center or call our Client
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• Do not pass belts over sharp edges.
• Do not make any modification that could
change the effectiveness of the belts.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).• Do not use handles above doors for placing
such items as coat hangers etc..• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.

cluster displayPractical hints Car care Index Notes:
Following a tire inflation pressure reactivation process
the real tire inflation pressures are displayed only after
a few minutes travel time.
Possible differences between readings of a tire pressure
gauge of an air hose, e.g. gas station equipment, and the
vehicle’s multifunction display can occur. The vehicle’s
multifunction display of the tire inflation pressure
monitor is a more precise reading.Activation of tire inflation pressure monitor
Activation of tire inflation pressure monitor is
necessary if tire inf lation pressure is being changed,
wheels or tires are replaced, or new wheels are installed
on the vehicle.
Tire inf lation pressure should be checked and corrected
according to the label affixed inside the fuel filler flap.
For a detailed description, refer to page 348.
Turn electronic key in starter switch to position 2 (the
engine must not be running).
Notes:
When checking the tire inflation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 338 for location of the spare wheel, and
page 348 for tire inflation pressure.
