Occupant safety
Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s instruc-
tions.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances re-
quire you to place a child in the front
passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropri-
ate child restraint on the front passen-
ger seat.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates in a collision
which could occur under some circum-
stances, even with the air bag technolo-
gy installed in your vehicle. The only
means to completely eliminate this risk
is to never place a child in a rear-facing
child restraint in the front seat. We
therefore strongly recommend that you
always place a child in a rear-facing
child restraint in the back seat.
If you must install a rear-facing child re-
straint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
75indicator lamp is illuminat-
ed, indicating that the front passenger
air bag is deactivated. Should the light
not illuminate or go out while the re-
straint is installed, please check installa-
tion. Periodically check the indicator
lamp while driving to make sure the
lamp is illuminated. If the
75indicator lamp goes out or
remains out, do not transport a child on
the front passenger seat until the sys-
tem has been repaired. A child in a
rear-facing child restraint on the front
passenger seat will be seriously injured
or even killed if the front passenger front
air bag inflates.

hints” section (
page 390).Installation of infant and child restraint
systems
Prior to installing a tether strap, note the
following steps:
Roll up retractable luggage cover and
partition net.
Remove storage box (if so equipped)
(page 269).
If the storage box is not removed:
the top tether anchorage ring located
on the floor (
page 87) for use with a
child restraint in the rear center seat
position cannot be accessed.
the hook of the top tether strap when
attached to the anchorage ring on an
outer rear seat backrest may push
against the storage box and prevent
the backrest from properly locking into
position.
If you place a child seat in the left or
center rear seat position, remove twin
roller blind (
page 271) and return
seat to its original position.
If you place a child seat in the right rear
seat position, the twin roller blind can
remain installed if so desired.
Fold the rear backrest slightly forward
(page 260).
Guide top tether strap between head
restraint and top of seat back.
Head restraints must be installed (if re-
movable) and positioned such that the
top tether strap can pass freely
between the head restraint and top of
the seat back.
Make sure the tether strap is not twist-
ed.
Fold the rear backrest back until it
locks in place (
page 261).
Warning!
G
If the indicator lamp should not illuminate,
the system is not functioning. You must see
an authorized Mercedes-Benz Center before
seating any child on the front passenger
seat.Warning!
G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat
must make full contact with the passenger
seat cushion. An incorrectly mounted child
seat could cause injuries to the child in case
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
!Do not reinstall twin roller blind with a
child seat and top tether installed in the
left and center rear seat position.

Driving safety systems
In this section you will find information on
the following driving safety systems:
ABS (A

BAS (B

ystem)
ESP
® (E
lectronic S
tability P
rogram)
Electrohydraulic brake system
4MATIC (Four Wheel Electronic
Traction System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
iIn winter operation, the maximum
effectiveness of the ABS, the BAS, the
ESP
®, electrohydraulic brake system
and 4MATIC is only achieved with win-
ter tires (
page 355), or snow chains
as required.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP
®, electrohydraulic brake
system and 4MATIC cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
