32 Getting startedUnlockingUnlocking with KEYLESS-GO*
If your vehicle is equipped with the
KEYLESS-GO function, your vehicle checks
whether the SmartKey with KEYLESS-GO is
valid when you grasp the door handle. If
your SmartKey with KEYLESS-GO is valid,
the doors will unlock, and you can open
them.
The function of the SmartKey overrules the
KEYLESS-GO function.
Grasp the outside door handle.
All turn signal lamps flash once. The
locking knobs in the doors move up.
If the SmartKey is inside the vehicle, press-
ing the KEYLESS-GO start/stop button on
the gear selector lever corresponds to
turning the SmartKey to the various starter
switch positions.iTo unlock the vehicle, the SmartKey
with KEYLESS-GO must be outside the
vehicle, no further than approximately
3 feet (1 meter) away from the door.
Warning!

AdjustingSeatsWarning!
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 in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 40).
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
SmartKey with KEYLESS-GO* with you, and
lock your vehicle.
Even with the SmartKey removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open. Therefore, 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.
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle's
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

36 Getting startedAdjustingHead restraint height
Press the switch up or down in the di-
rection of arrow1.Head restraint tilt
Manually adjust the angle of the head re-
straint.
Push or pull on the lower edge of the
head restraint cushion.
For more information, see “Seats”
(
page 108).
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iThe feature below is deactivated at the
factory. If you wish to have it activated,
contact an authorized Mercedes-Benz
Center:
The front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied. This improves the
driver'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.

Adjust the interior and exterior rear view
mirrors before driving so that you have a
good view of the road and traffic condi-
tions.Interior rear view mirror
Manually adjust the interior rear view
mirror.

ror” (page 174).Exterior rear view mirror
Warning!
G
In the case of an accident, liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.

Fastening the seat belts
Warning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate.
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The airbags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 58).
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart

bag when it is properly installed. Otherwise
