34 Getting started
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information, see “Seats”
(
page 101).
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 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 back 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 43).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, 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. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

Steering wheel
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
Warning!G
Do not adjust the steering wheel while
driving. Adjusting the steering wheel while
driving, or driving without the steering wheel
adjustment feature locked could cause the
driver to lose control of the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the electrical steering wheel
adjustment feature* can be operated when
the driver’s 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.

68 Safety and Security
Occupant safety
The 56indicator lamp is located in
the center console.
1Front passenger front air bag off
indicator lamp
The 56indicator lamp1 will be
illuminated, except with the SmartKey
removed from the starter switch or with
the starter switch in position0.Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position1 or2, the
56indicator lamp located in the
center console illuminates. If an adult oc-
cupant is properly sitting on the front pas-
senger seat and the system senses the
occupant as being an adult, the
56indicator lamp will illuminate
and go out after approximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 56indicator lamp will
illuminate and not go out.
Warning!G
If the 1indicator lamp and the
56indicator lamp are lit at the same
time, there is a malfunction in the Occupant
Classification System. The front passenger
front air bag will be deactivated in this case.
In order to ensure proper operation of the air
bag system and OCS:

Have the system checked as soon as
possible by qualified technicians.
Contact an authorized Mercedes-Benz
Center.

Sit properly belted in a nearly upright
position with your back against the seat
backrest.

Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.

Only have the seat repaired or replaced
by an authorized Mercedes-Benz Cen-
ter.

Read and observe all warnings in this
chapter.

intensity for a maximum of 60 seconds
or until the driver’s and the front pas-
senger’s seat belt are fastened.
If you and/or your passenger release
the seat belt during driving, the seat
belt telltale < starts flashing and a
warning chime sounds as described be-
fore.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
After a vehicle standstill the warning
chime is reactivated and the seat belt
telltale < is flashing again if the ve-
hicle speed once exceeds 15 mph
(25 km/h).
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.For more information, see “Practical hints”
(
page 328).
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency
tensioning devices and belt force limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding the system deployment
threshold.

if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 58).When activated, emergency tensioning
devices remove slack from the belts. Belt
force limiters reduce the force exerted by
the seat belts on occupants during a crash.
iThe ETDs for the front seats will only acti-
vate if the respective front seat belt is fastened
(latch plate properly inserted into buckle).
The ETDs for the rear outer seats will activate
with or without the respective seat belt fastened.
Warning!G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing the emergency tensioning
device, our safety instructions must be
followed. These are available at your
authorized Mercedes-Benz Center.

73 Safety and Security
Occupant safety
Active head restraint
The active front seat head restraints are in-
tended to offer the driver and front passen-
ger increased protection from whiplash
type injuries in rear-end collisions. In the
event of a rear-end collision exceeding the
systems’ deployment threshold, the active
head restraints on the driver’s and front
passenger’s seats are designed to move
forward in the direction of travel, providing
the head with increased support earlier on
in the collision sequence. The active head
restraints activate whether the seat is oc-
cupied or not.You cannot remove the active head re-
straints on the driver’s and front passen-
ger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Center.
For information on head restraint adjust-
ment, see “Seats” (
page 34).
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 365).
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the
potential 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
accident.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraints. Contact an
authorized Mercedes-Benz Center for
availability.
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the ac-
tive head restraints may not be able to func-
tion properly or offer the intended degree of
protection in the event of an accident.

77 Safety and Security
Occupant safety
Installation of infant and child restraint
systems
This vehicle is equipped with tether
anchorages for a top tether strap at each
of the rear seating positions.
1Cover of top anchorage ring
Make sure the rear backrest is locked
in its upright position (
page 235).
Warning!G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
