Installing child restraints using a seat belt (child restraint lock function belt)
■Rear-facing Infant seat/convertible seat
Place the child restraint system on
the rear seat facing the rear of the
vehicle.
Run the seat belt through the child
restraint system and insert the
plate into the buckle. Make sure
that the belt is not twisted.
Fully extend the shoulder belt and
then allow it to retract slightly in
order to activate the ALR lock
mode.
Lock mode allows the seat belt to
retract only.

While pushing the child restraint
system down into the rear seat,
allow the shoulder belt to retract
until the child restraint system is
securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■Forward-facing Convertible seat
Place the child restraint system on
the seat facing the front of the vehi-

CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: (P. 7 8 )
ALR mode causes the belt to tighten only which could cause injury or discomfort to
the child.
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it
does not interfere with the child restraint
system.
●Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint on the front passenger seat, move
the seat as far back as possible even if the
“AIR BAG OFF” indicator light is illumi-
nated. Failing to do so may result in death
or serious injury if the airbags deploy
(inflate).

CAUTION
■When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from
the child’s neck, but not so that it could fall off the child’s shoulder. Failing to do so
may result in death or serious injury in the event of sudden braking, sudden
swerving or an accident.
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child restraint system from side to side and forward to be sure it
is secure.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of sudden stop, sudden swerve
or an accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint system.
Make sure the child restraint system is securely attached, or it may cause death or
serious injury to the child or other passengers in the event of a sudden stop, sudden
swerve or accident.

PCS (Pre-Collision System)
: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact and injuries to occupants as well as
vehicle damage.
■Pre-collision seat belts (front seats only)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 7 7 )
■Pre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
■Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automatically
applied to reduce the collision speed. Pre-collision braking can be dis-
abled using the pre-collision braking off button.
■AV S
If the system determines that the collision is unavoidable, the operation of
AV S (P. 213) helps prevent the vehicle front from going down when
hard brakes are applied.

■Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be occa-
sions when the radar sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.
■The pre-collision system is operational when
●Pre-collision seat belts (linked to the radar sensor)
• Vehicle speed is above 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming
vehicle exceeds 18 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (linked to brake operation)
• Vehicle speed exceeds 18 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.

• Vehicle speed is above 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming
vehicle exceeds 18 mph (30 km/h).
• The brake pedal is depressed.
●Pre-collision braking
• The pre-collision braking off button is not pressed.
• Vehicle speed is greater than about 9 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle
running ahead of you is greater than about 9 mph (15 km/h).
