sumers, such as seat adjustment2Ignition (power supply for all electrical
consumers) and driving position.
All lamps (except low beam headlamp
indicator lamp, high beam headlamp
indicator lamp, and turn signal indica-
tor lamps unless activated) in the
instrument cluster come on. If a lamp
in the instrument cluster fails to come
on when the ignition is switched on,
have it checked and replaced if neces-
sary. If a lamp in the instrument cluster
remains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (
page 378).

When you switch on the ignition, the indica-
tor and warning lamps (except low beam head-
lamp indicator lamp, high beam headlamp
indicator lamp, and turn signal indicator lamps
unless activated) in the instrument cluster come
on. The indicator and warning lamps (except low
beam headlamp indicator lamp, high beam head-
lamp indicator lamp, and turn signal indicator
lamps if activated) should go out when the en-
gine is running. This indicates that the respective
systems are operational.

position0 for an extended period of time, it can
no longer be turned in the switch. In this case,
the steering is locked. To unlock, remove
SmartKey from the starter switch and reinsert.

If the SmartKey cannot be turned in the
starter switch, the battery may not be sufficient-
ly charged.
Check the battery and charge it if necessary

unit will not allow front passenger front
air bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the 75 indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
front passenger front air bag is deactivated.

Important notes on using KEYLESS-GO
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 110).
You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with button ‹).
Always carry the SmartKey with
KEYLESS-GO with you.
Never store the SmartKey with
KEYLESS-GO together with:
Electronic items such as a cellular
phone or another SmartKey with
KEYLESS-GO
Metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.
To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft (1 m) of a door or the
tailgate.
In order to start the engine with the
SmartKey with KEYLESS-GO:
The SmartKey with KEYLESS-GO
must be located in the vehicle.
The brake pedal must be firmly de-
pressed. Do not depress the accel-
erator.
If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle cannot be locked or the
engine started via the KEYLESS-GO
system.
If the SmartKey with KEYLESS-GO is re-
moved from the vehicle (e.g. if passen-
ger exits the vehicle with the SmartKey
with KEYLESS-GO)
when pressing the KEYLESS-GO
start/stop button or trying to lock
the vehicle with the outside door
handle the message
Key not rec-
ognized
appears in the multifunc-
tion display
!
If you can no longer lock or unlock the vehi-
cle with the SmartKey with KEYLESS-GO, then
the batteries in the SmartKey with KEYLESS-GO
are discharged, the SmartKey with KEYLESS-GO
is malfunctioning or the vehicle battery is
drained.
Check the batteries in the SmartKey with
KEYLESS-GO (
page 119) and replace
them if necessary (page 440).
Use the mechanical key to unlock the driv-
er’s door (
page 435).
Use the mechanical key to lock the driver’s
door.
Have the vehicle battery checked by an au-
thorized Mercedes-Benz Center.
If the SmartKey with KEYLESS-GO is malfunc-
tioning, contact an authorized Mercedes-Benz
Center.
