Booster seat
Adjusting the angle of the seat-
back.
While pulling the lever, fold the
seatback forward and then back
to the 1st lock position (most
upright position) until it locks into
place.
Place the booster seat on the
seat facing the front of the vehi-
cle.
Sit the child in the booster seat.
Fit the seat belt to the booster
seat according to the manufac-
turer’s instructions and insert the
plate into the buckle. Make sure
that the belt is not twisted.
Check that the shoulder belt is
correctly positioned over the
child’s shoulder and that the lap
belt is as low as possible.

Child restraint systems with a top tether strap
Secure the child restraint system
using the seat belt or the LATCH

Laws and regulations pertaining to anchors
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifica-
tions can be used.
This vehicle is designed to conform to the SAE J1819.
CAUTION
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. (P. 101)

CAUTION
■
When installing a child restraint system
● When installing a child restraint system in the rear center seat, adjust both
seat cushions to the same position and align both seatbacks at the same
angle. The seatbacks must be adjusted to the same angle. Otherwise, the
child restraint system cannot be securely restrained and this may cause
death or serious injuries in the event of sudden braking, sudden swerving
or an accident.
● When using the LATCH system, move the seat as far back as possible
and adjust the seatback as upright as possible.
● When a booster seat is installed, always ensure that the shoulder belt is
positioned 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 that the belt and plate are securely locked and 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
manufacturer.

CAUTION
■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 sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child r estraint 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 possibility of a frontal collision, the
pre-collision systems such as the brakes and seat belts are automat-
ically engaged to lessen impact to occupants as well as vehicle dam-
age.
■ Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects t hat 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. 100)
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system 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 sys-
tem determines that a collision is unavoidable, the brakes are automat-
ically applied to reduce the collision speed. Pre-collision braking can be
disabled using the pre-collision braking off switch.

■The pre-collision system is operational when
● Pre-collision seat belts (operating conditions A):
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
● Pre-collision seat belts (operating conditions B):
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt.
● Pre-collision brake assist:
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.
● Pre-collision braking:
• Vehicle speed is greater than about 10 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 10 mph (15 km/h).
• The pre-collision braking off switch is not pressed.

When driving
■Conditions that may trigger the system even if there is no possibility of
a collision
● When there is an object by the roadside at the entrance to a curve
● When passing an oncoming vehicle on a curve
● When driving over a narrow iron bridge
● When there is a metal object on the road surface
● When driving on an uneven road surface (nose up, nose down)
● When passing an oncoming vehicle on a left-turn
● When your vehicle rapidly closes on the vehicle in front
● When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
● When the steep angle of the road causes a metal object located beneath
the road surface to be seen ahead of the vehicle
● When an extreme change in vehicle height occurs
● When the axis of the radar is out of adjustment
● When passing through certain toll gates
● When passing through an overpass
When the system is activated in the situations described above, there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
■ Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
