88 Controls in detailLocking and unlocking
In the “Controls in detail” section you will
find detailed information on how to oper-
ate the equipment installed on your vehi-
cle. If you are already familiar with the
basic functions of your vehicle, this section
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, refer to the
“Getting started” section of this manual.
The corresponding page numbers are giv-
en at the beginning of each segment.
Locking and unlocking
SmartKeys
Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key. The locking
tabs for the mechanical key portion of the
two SmartKeys are a different 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.
The SmartKey centrally locks and unlocks:
the doors
the glove box
the trunk lid
the fuel filler flap

Important notes on using KEYLESS-GO*
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 88).
You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with the remote control).
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
Warning!

SmartKey from the starter switch, take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.iYou can also open and close the soft
top (
page 222) and the power win-
dows (page 213) using the
SmartKey.
iIf the vehicle has been parked for a
longer period of time, you must pull the
door handle in order to activate the

To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when stowing objects in the vehicle. Put lug-
g a g e o r c a r g o i n t h e t r u n k i f p o s s i b l e . D o n o t
pile luggage or cargo higher than the seat
backs.
Luggage nets cannot secure hard or heavy
objects.

to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.
!Make sure no objects fall into the open-
ings of the subwoofer between the rear
seats.
If necessary, contact an authorized
Mercedes-Benz Center to remove any
objects which may have fallen into the
openings.

ment for eyeglasses.
