30 Getting startedUnlockingThe “Getting started” section provides an
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
functions described here, the “Controls in
detail” section will help you with further in-
formation. The corresponding page refer-
ences are at the end of each segment.
UnlockingUnlocking with the SmartKey
Your vehicle comes equipped with two
SmartKeys with integrated remote con-
trols and removable mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys are a differ-
ent color to help distinguish each
SmartKey unit.SmartKey with remote control 1‹

on the
SmartKey.
All turn signal lamps blink once. The
locking knobs in the doors move up.

Get in the vehicle and insert the
SmartKey in 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.

34 Getting startedAdjusting
Adjusting
Seats
Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could
slide under the seat belt in a collision. If you
slide under it, the belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat backrest and
seat belts provide the best restraint when
the wearer is in an upright position and belts
are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
KEYLESS-GO* card (if so equipped) with
you, and lock your vehicle.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

37 Getting started
Adjusting
Head restraint height
Press the switch up or down in the di-
rection of arrow1.
Head restraint tilt

Manually adjust the angle of the head
restraint. Push or pull on the lower
edge of the head restraint cushion.
For more information, see “Front seat head
restraints” (
page 105).
Steering wheel
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint to support the back of
the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iThe front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied. This improves the driv-
er’s outward view as well as the for-
ward view from the rear passenger
compartment.
When the front passenger seat is occu-
pied again, the front passenger seat
head restraint returns to the last set
position within a few seconds.
If the front passenger seat was moved
fore or aft while not being occupied,
the front passenger seat head restraint
returns to a position that corresponds
best with the seat’s axial position when
the seat is occupied again.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch, and take
the KEYLESS-GO
* card (if so equipped) with
you.
The steering wheel adjustment feature can
also be operated with the driver’s door
open. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

44 Getting startedDrivingStarting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the KEYLESS-GO card.
or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the KEYLESS-GO
card.

Repeat the starting procedure
(page 42). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 347).If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Center.
