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 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 back and seat belts provide the
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned 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, and lock
your vehicle.
The power seats can also be operated with
the driver’s or front passenger door open.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised 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 the back seats and be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt and top tether strap, or
secured via lower anchors and top tether
strap, fully in accordance with the child seat
manufacturer’s instructions.

Adjust to a comfortable seating posi-
tion that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far to the rear as
possible, consistent with ability to
properly operate controls.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iWhen moving the seat, be sure that
there are no items in the footwell or
behind the seats
the cup holder next to the armrest
is removed (
page 185)
the cup holder in the front passen-
ger footwell is folded closed
(page 185)
Otherwise you could damage the seats
and/or cup holders.
The memory function (
page 101) lets
you store the setting for the seat posi-
tion together with the setting for the
steering wheel and the exterior rear
view mirrors.
40 Getting startedDriving
DrivingFastening the seat beltWarning!
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 maneu-
vers, 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 protect as ex-
pected if the occupants are using their seat
belts (
page 56).

In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
Occupant safety
The restraint systems are
Seat belts
Emergency tensioning device
Airbags
Child seats
Child seat recognition
Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each oth-
er.The 1indicator lamp in the instrument
cluster (
page 25) comes on:
for about four seconds when you turn
the SmartKey in the starter switch to
position1.
for about four seconds when you start
the engine by turning the SmartKey.
The 1indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).
iThe 1indicator lamp remains lit if
the SmartKey is turned to position2
and left there. The indicator lamp will
go out when you start the engine.

Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag
(
page 68).
iAirbags are designed to activate only in
certain frontal (front airbags) impacts
which exceed preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment thresholds, will they provide their
supplemental protection.
The driver and passenger should al-
ways wear their seat belts. Otherwise it
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents, the airbags will not be acti-
vated. The driver and passengers will
then be protected by the fastened seat
belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
62 Safety and SecurityOccupant safetyThe airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The passenger front airbag will only be de-
ployed if:
the passenger seat is occupied
the 7 indicator lamp in the center
console is not lit (
page 68)
the impact exceeds a preset deploy-
ment threshold
Seat belts
When the engine is started, the seat-belt
non-usage warning lamp< illuminates
to remind you and your passengers to fas-
ten your seat belts. If the driver’s seat belt
is not fastened before the engine is start-
ed, the seat belt non-usage warning
lamp< illuminates and a warning
chime sounds for approximately six sec-
onds when the engine is started.
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia and all
Canadian provinces. Even where this is not
the case, all vehicle occupants should have
their seat belts fastened whenever the ve-
hicle is in motion.For more information, see “Fastening the
seat belt” (
page 40).
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the passenger
front airbag to deploy in a crash which
exceeds the system’s deployment
threshold.
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).
65 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate only when
the seat belt is fastened and in the follow-
ing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 56)
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.
Make sure the infant or child is proper-
ly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Light Truck Center.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Light Truck Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the passenger
front airbag to deploy in a crash which
exceeds the system's deployment
threshold.
