Before driving
CAUTION
■
When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR
lock mode: ( P. 87)
ALR mode causes the belt to tighten only which could cause injury or dis-
comfort 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
passengers may be seriously injured or even killed in the event of sudden
braking 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 or sec-
ond seats so that it does not interfere
with the child restraint system.
● Only put a forward-facing or booster
child seat on the front seat when
unavoidable. When installing a forward-
facing or booster child seat on the front
passenger seat, move the seat as far
back as possible even if “AIR BAG
OFF” indicator light is illuminated. Fail-
ing to do so may result in death or seri-
ous injury if the airbags deploy (inflate).

154 1-7. Safety information
CAUTION
■When installing a child restraint system
●When installing a child restraint system in the third center seat, adjust both
seatbacks at the same angle. Otherwise, the child restraint system cannot
be securely restrained and this may cause death or serious injuries in a
collision.
● When using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
● 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 an accident or sudden braking.
● Ensure that the belt and tab are securely locked and the seat belt is not
twisted.
● Push and pull the child seat in different directions 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.
● Third seats: When a child restraint system with a top tether strap is
installed, do not install the head restraint. The head restraint may interfere
with the top tether strap preventing secure installation of the child restraint
system.
● Make sure to properly store the removed head restraint in a secure place
when you use the child restraint system on the third seat.
■ 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 a colli-
sion.

Before driving
CAUTION
■
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. 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 or accident.

164 2-1. Driving procedures
CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
■ If the vehicle becomes stu ck or bogged (AWD models)
Do not spin the wheels recklessly when any of the tires is up in the air, or
stuck in sand or mud, etc. This may damage the drive system components
or propel the vehicle forward (or in another direction) and cause an accident.
