Before driving Run the seat belt through the child
restraint system and insert the
plate into the bu ckle. Make sure
that the belt is not twisted.
Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt can-
not be extended.
While pushing the child restraint
system 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.
If the child restraint has a top tether strap, the top tether strap
should be latched onto th e top tether strap anchor. (  P. 161)STEP 3

Before driving CAUTION■
When installing a child restraint system
Follow the directions given in the child re straint system installa tion manual and fix
the child restraint system securely in place.
If the child restraint system is not correctl y 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.
●
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 sys-
tem 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 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 inju ry 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 passen ger 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 system on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failure to do so may result in
death or serious injury if the airbags deploy
(inflate).

1641-8. Safety information
CAUTION■
When installing a child restraint system ●
Ensure that the belt and tab are securely locked and the seat belt is not twisted.●
Shake the child restraint system left and right, and forward and backward to
ensure that it has be en securely installed.●
After securing a child restraint system, never adjust the seat.●
Follow all installation instructions provid ed by the child restraint system manufac-
turer.■
Do not use a seat belt extender
If a seat belt extender is used when inst alling 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 braking, sudden
swerving 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 no t caught behind the child restraint system.
Make sure the child restraint system is se curely attached, or it may cause death or
serious injury to the child or other passen gers in the event of a sudden stop, sudden
swerve or accident.

2782-4. Using other driving systems
Pre-Collision System When the radar sensor detects the possib ility of a frontal collision, the pre-
collision system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.
■ Pre-collision seat belts (front seat belts 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. 1 0 0 )
However, the system will not operate in the event of skidding when the
VSC system is disabled.
■ 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. The system may not warn the driver using a warning light,
warning display and buzzer when the system detects and judges braking
operations.
■ Pre-collision braking When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warnin g 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 switch.

When driving ■
Conditions that may trigger the system even if there is no possibility of 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●
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 climbing a steep hill causes an over head billboard or ot her metallic struc-
ture to appear directly in the vehicle's line of travel●
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 driving on a bridge●
When passing through a tunnel
When the system is activated in the situations described above, there is also a possi-
bility 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, motorcy-
cles, trees, or snowdrifts.

2922-5. Driving information
Utility vehicle precautions Utility vehicle feature
● Specific design characteristics give it a higher center of gravity than
ordinary passenger cars. This vehicle design feature causes this type of
vehicle to be more likely to rollov er. And, utility vehicles have a signifi-
cantly higher rollover rate than other types of vehicles.
● It is not designed for cornering at the same speeds as ordinary passen-
ger cars any more than low-slung sports cars designed to perform sat-
isfactorily under off-road condit ions. Therefore, sharp turns at
excessive speeds may cause rollover. CAUTION■
Utility vehicle precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle: ●
In a rollover crash, an unbelted person is significantly more likely to die than a
person wearing a seat belt. Therefore, the driver and all passengers should fasten
their seat belts whenever the vehicle is moving.●
Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or vehicle roll-
over causing death or serious injury.
●
Loading cargo on the roof luggage carrier will make the center of the vehicle
gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover
due to failure to operate this vehicle correctly.This vehicle belongs to the utilit y vehicle class, which has higher
ground clearance and narrower tread in relation to the height of its
center of gravity.
