Observe the safety precautions > page 76. The
front passenger’s seat is a dangerous location for
a child, even with an advanced airbag system. If
exceptional circumstances require the child safe-
ty seat to be placed on the front passenger's
seat, then the front passenger's airbag must be
deactivated. Please note the important informa-
tion for this > page 77, Correct positioning for
children and > page 74, Advanced airbag sys-
tem.
Securing child safety seats
> Activate the child safety lock > page 44.
> If you secure a child safety seat to the rear seat,
secure any unused safety belts that are within
reach of the child > A\, > page 81.
> If you secure a child safety seat to the front
passenger's seat, adjust the front passenger's
seat to the highest position.
> Secure the child safety seat according to the
child safety seat manufacturer instructions.
> If necessary, activate the belt retractor lock
=>page 79.
> If the child safety seat is secured on the front
passenger's seat, adjust the front passenger's
seat backrest until it rests flat against the child
safety seat. Also make sure that the upper safe-
ty belt fixture is behind the child safety seat.
> If you secure a child safety seat on the rear
seat, also secure it to the correct top tether an-
chor if possible > page 80.
Activating the belt retractor lock
If you secure a child safety seat using the vehicle
safety belt, you must activate the belt retractor
lock. Follow the child safety seat manufacturer
instructions.
The belt retractor lock prevents the safety belt
from becoming loose while driving, which could
result in the child safety seat no longer being ad-
equately secured.
> Secure the child safety seat according to the
child safety seat manufacturer instructions.
While doing so, pull out the safety belt. Insert
the safety belt into the belt latch that belongs
to that seat until it audibly locks.
> Pull the upper belt out completely and then al-
low it to retract. You will hear a clicking sound
while the belt is retracting. It will not be possi-
ble to pull the safety belt out any farther.
> Push the child safety seat into the seat and al-
low the belt to retract more.
> Make sure that the child safety seat cannot
move more than 1 inch (2.5 cm).
Deactivating the belt retractor lock
> Unbuckle the safety belt from the belt latch.
> Remove the child safety seat according to the
manufacturer instructions.
> Allow the safety belt to retract completely. The
belt retractor lock is deactivated.

ZA WARNING
— A safety belt that is not locked by the belt
retractor lock or a locking device cannot se-
cure a child safety seat while driving or in
the event of an accident, which increases the


risk of fatal injury. Always make sure the >

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.

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.


84
() 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.
