Fig. 73 Rear bench seat: securing unused safety belts
If a child safety seat is used on the rear bench
seat, the child must not be able to reach any
safety belts that are not being used. Secure safe-
ty belts that are within reach of the child.
> If you secure a child safety seat to the LATCH
anchors, fasten the safety belt on the seat
where the child safety seat is installed using
the seat's safety belt latch.
> If you secure a child safety seat to one of the
outer seats, fasten the safety belt for the cen-
ter seat in its latch.
> Activate the belt retractor lock on the fastened
safety belts. To do this, pull the upper belt out
completely and then allow it to retract. You will
hear a clicking sound while the belt is retract-
ing. It will not be possible to pull the safety
belt out any farther.
> Make sure the fastened safety belt does not
block access to the LATCH anchors. Otherwise,
it may not be possible to secure the child safety
seat to the LATCH anchors correctly.

A child ina child safety seat could play with
the unused safety belts and then become en-
tangled in them, which increases the risk of


fatal injury. Always secure unused safety belts
so that they are not within reach of children in
child safety seats.

Storage and
compartments
Storage area behind the rear head
restraints
Applies to: vehicles with storage area behind the rear head re-
straints
The storage area can be used to carry light pieces
of clothing.

Z\ WARNING
The storage compartment must not be used
to transport heavy objects, hard objects, or
animals. Such objects endanger vehicle occu-
pants and increase the risk of injury during
sudden driving or braking maneuvers or in an
accident.
@) Note
Make sure that the heating grid strips for the
rear window defogger are not damaged by
abrasive objects.
@ Tips
To ensure the ventilation functions correctly,
the ventilation slots between the rear window
and the storage area must not be covered.
Additional storage options
Depending on vehicle equipment, there are a va-
riety of storage areas, compartments, and retain-
ers, such as the glove compartment, for safely
storing and securing objects.

Z\ WARNING
—To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-

ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Due to strength reasons, only secure objects
up to 11 lbs (5 kg) with the straps* in the
luggage compartment. Heavier objects are
not adequately secured. There is risk of per-
sonal injury.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or
objects in the vehicle.


Luggage compartment
General information

fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
> Use non-elastic cords attached to the tie-downs
to secure objects.

Z\ WARNING
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er is not a surface for storing objects. Ob-
jects placed on the cover increase the risk of

Storage and convenience


— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er must always be securely fastened when in
use to reduce the risk of an accident.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net* is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 287.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave
the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-
rectly secured with the safety belts in the
vehicle > page 68.
— Be careful when releasing the backrest and
folding
it forward. To reduce the risk of be-


ing pinched, pay attention and check when
folding backrests forward.
— The backrest must be securely latched so
objects cannot slide forward out of the lug-
gage compartment during sudden braking.
— The backrest must be latched securely to en-
sure that the safety belt is protecting the
center seating position.
— Always pull forward on the backrest to make
sure it is check if it is correctly locked in
place.

() Note
—To reduce the risk of damage, move the rear
head restraints down > page 67 before fold-
ing the rear backrests forward.
— When folding the backrest forward, make
sure the outer safety belts are in the belt
guide recess so that they do not get pinched
in the backrest lock and damaged. Other ob-
jects should be removed from the rear
bench seat to protect the backrest from
damage.
— To reduce the risk of damaging the front
seats, make sure there is enough space be-
tween the front seat and the rear seat
equipment when folding the center backrest
forward.
— If you move the front seat back when the
rear seat backrest is folded forward, you
could damage the head restraints on the
rear seat.
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Applies to: vehicles with manual luggage
compartment cover: Let the luggage com-
partment cover roll up slowly to reduce the
risk of damage.
— Applies to: vehicles with partition net: Let
the partition net roll up slowly to reduce the
risk of damage.
