possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Occupant safety
Important safety notes
GWARNING
Modifications to the restraint systems could
result in them not functioning properly any
more. The restraint systems could then no
longer protect vehicle occupants as they are
designed to do and could fail in the event of
an accident or activate unexpectedly, for
example. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz center.
USA only: for further information contact our
Customer Assistance Center at
1-800-FOR-MERCedes (1800-367-6372).
In this section, you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
RSeat belts
RChild restraint systems
RLATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
RSRS (Supplemental Restraint System)
RPRE-SAFE®
RAir bag system components with:
-PASSENGER AIR BAG OFF indicator lamp
-Front-passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their
protective functions work in conjunction with
each other. Not all air bags are always
deployed in an accident.
iFor information on infants and children
traveling with you in the vehicle restraint
systems for infants and children, see
"Children in the vehicle" (Ypage 60).

Safety

Observe the warning labels in the vehicle
interior or on the infant or child restraint.
Special seat belt retractor
GWARNING
If you release the seat belt when driving, the
special seat belt retractor is deactivated.
The released seat belt cannot be engaged
again while driving, because the inertia reel
pulls in the seat belt a small distance. The
child restraint system is no longer properly
secured. There is an increased risk of serious
injury or even fatal injury.
Always keep the seat belt of the activated
special seat belt retractor engaged when
driving.
All seat belts except the driver's seat belt are
equipped with a special seat belt retractor.
When activated, the special seat belt
retractor ensures that the seat belt will not
slacken once the child restraint system has
been secured.
Installing a child restraint system:
XAlways comply with the manufacturer's
installation instructions.
XPull the seat belt smoothly from the seat
belt retractor.
XEngage the seat belt tongue in the belt
buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the seat
belt retractor retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat
belt retractor is activated.
XPush down on the child restraint system to
take up any slack.
Removing a child restraint system/
deactivating the special seat belt retractor:
XAlways comply with the manufacturer's
installation instructions.
XPress the seat belt release button and
guide the belt tongue to the belt outlet.
The special seat belt retractor is
deactivated.
LATCH-type (ISOFIX) child seat anchors
in the rear
GWARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt
integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
When installing a child restraint system, be
sure to observe the manufacturer's
installation instructions and the instructions
for correct use of the child restraint system.
To ensure that the LATCH-type (ISOFIX) child
restraint system can perform its protective
function as intended, the backrest of the
respective outer seat in the second row must
be in the upright position.
!When installing the LATCH-type (ISOFIX)
child restraint system, make sure that the
seat belt for the center seat does not get
trapped. Otherwise, the seat belt could be
damaged.

Securing ringsDfor two LATCH-type
(ISOFIX) child restraint systems are installed
on the left and right:
Ron the rear seat backrests of the outer
seats in the second row
Ron the backrests of the seats in the third
row of seats
Before installing a LATCH-type (ISOFIX) child
restraint system in the second row:
XMove the rear seat backrests in the second
row to an upright position (Ypage 111).
XInstall the LATCH-type (ISOFIX) child
restraint system on both LATCH-type
(ISOFIX) securing ringsD. Comply with the
child restrain system manufacturer's
instructions when installing the LATCH-
type (ISOFIX) child restraint system.
Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
vehicle's seat belt system. Install the child
seat according to the manufacturer's
instructions.
Top Tether
Top Tether anchorages
GWARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an
accident, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g.
in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after
installing a Top Tether belt. Observe the lock
verification indicator. Adjust the rear seat
backrests so that they are positioned
vertically.
Top Tether provides an additional connection
between the LATCH-type (ISOFIX) child
restraint system secured with LATCH-type
(ISOFIX) and the rear seat. This helps reduce
the risk of injury even further. If the LATCH-
type (ISOFIX) child restraint system is
equipped with Top Tether, this should always
be used.
The Top Tether anchorages for the second
row of seats are installed on the rear of the
rear seat backrests. For the third row of seats,
use the cargo tie-down rings in the cargo
compartment floor.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster.
