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
belt retractor lock on the safety belt is acti-
vated if the child safety seat manufacturer
instructions require it.
— Due to the risk of fatal injury, never place a
rear-facing child safety seat on the front
passenger's seat when the front passenger's
airbag is switched on.
— For the child safety seat to offer the maxi-
mum protection, it is especially important
to route the vehicle safety belt correctly. Al-
ways follow the instructions from the child
safety seat manufacturer for routing the
safety belt correctly. Incorrectly fastened
safety belts can cause injuries, even during

minor accidents.

Fig. 67 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.

ZA WARNING
A child in a 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.

Luggage compartment
General information
All pieces of luggage or objects must be securely
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.

ZA\ WARNING
— The luggage compartment cover must al-
ways be securely fastened when in use to re-
duce the risk of an accident.
— The storage compartment must not be used
to transport heavy objects, hard objects, or
animals. Such objects endanger vehicle oc-
cupants and increase the risk of injury dur-
ing sudden driving or braking maneuvers or
in 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

injury during braking maneuvers or acci-
dents.
— 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 262.
— 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 59.
—To reduce the risk of accidents, the luggage
compartment cover should never be unse-
cured
under any circumstances.
— 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.

CG) Note
—To reduce the risk of damage, move the rear
head restraints down > page 58 before fold-
ing the rear backrests forward.
— Objects should be removed from the rear
bench seat to protect the backrest from
damage.
— 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.

When driving
Starting to drive, stopping, and parking
Starting from a stop
> Press and hold the brake pedal.
> Start the engine.
> Select a gear.
> Release the parking brake.
> Release the brake pedal. The vehicle may roll.
> Press the accelerator pedal to accelerate.
Stopping and parking
> Bring the vehicle to a full stop and press and
hold the brake pedal.
> Set the parking brake.
> Select the “P” selector lever position to secure
the vehicle from rolling away.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.
> Switch off the ignition before leaving the vehi-
cle.
On hills, activate the parking brake first and then
shift into the "P" selector lever position. This pre-
84
vents too much stress from being placed on the
locking mechanism.

Z\ WARNING
— Always set the parking brake when leaving
your vehicle, even if for a short period of
time. If the parking brake is not set, the ve-
hicle could roll away, increasing the risk of
an accident.
— Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If you leave the vehicle, switch the ignition
off and take the key with you. This is espe-
cially important when leaving persons or an-
imals in the vehicle. Otherwise, the vehicle
could start unintentionally, the parking
brake could release, or electronic equipment
could activate, which increases the risk of an
accident.
— No persons or animals should be left in a
locked vehicle. Locked doors make it more
difficult for emergency workers to enter the
vehicle, which puts lives at risk.
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal
or set the parking brake immediately.
C) Note
If you have to stop on an incline, always press
the brake pedal to hold the vehicle in place to
reduce the risk of the vehicle rolling back-
ward. Do not try to hold the vehicle in place
by pressing and holding the accelerator pedal.
The transmission can overheat, which increas-
es the risk of damage.
