overview of the vehicle’s most basic func-
tions. First-time Mercedes-Benz owners
should pay special attention to the infor-
mation given here.
If you are already familiar with the basic

formation. The corresponding page refer-
ences are at the end of each segment.

When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
KEYLESS-GO* card (if so equipped) with you
and lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in position P.

position 0 for an extended period of
time, it can no longer be turned in the
starter switch.
Remove the SmartKey from the
starter switch and reinsert.
If the SmartKey can still not be turned,
the battery may not be sufficiently
charged.
Check the battery and charge it
if necessary (

page 347).
To prevent accelerated battery dis-
charge or a completely discharged bat-
tery, always remove the SmartKey from
the starter switch.

32 Getting startedUnlockingUnlocking with KEYLESS-GO*
Vehicles with KEYLESS-GO*: In addition to
the two SmartKeys with remote controls
and removable mechanical key, your vehi-
cle comes equipped with two
KEYLESS-GO* cards.
The function of the SmartKey overrules the
KEYLESS-GO function.If you have the KEYLESS-GO function, your
vehicle checks whether the KEYLESS-GO
card is valid when you grasp the door han-
dle. If your KEYLESS-GO card is valid, the
doors will unlock, and you can open them.
Grasp the door handle.
All turn signal lamps blink once. The
locking knobs in the doors move up.Pressing the KEYLESS-GO start/stop but-
ton on the selector lever corresponds to
turning the key to the various starter
switch positions.iTo unlock the vehicle, the KEYLESS-GO
card must be outside the vehicle, no
further than approximately 3 feet
(1 meter) away from the door.
Warning!
G
When leaving the vehicle, always take the
SmartKey and the KEYLESS-GO card with
you, and lock the vehicle. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.
