■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
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, it may result in
death or serious injury to the child or other passengers in the event of sud-
den 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.

CAUTION
■
When installing a 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 sudden braking, sudden swerving or an accident.
● Ensure that the belt and tab 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.
■ 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.
● Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if “AIR BAG OFF” indi-
cator light is illuminated. Failing to do
so may result in death or serious injury
if the airbags deploy (inflate).

CAUTION
■
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, you may accidentally move the
shift lever or depress the accelerator pedal, which could cause an accident
or fire due to hybrid system overheating. Additionally, if the vehicle is parked
in a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading 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 downhill 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.
● The brake system consists of 3 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.

■Rear view monitor system camera
■ Smear effect
In the following cases, it may be difficult
to see the images on the screen, even
when the system is functioning correctly.
• In the dark (e.g. at night).
• If the temperature near the lens is
extremely high or low.
• If water droplets get on the camera, or when humidity is high (e.g. when it
rains).
• If foreign matter (e.g. snow or mud) get on the camera lens.
• If the sun or headlights are shining directly into the camera lens.
If a bright light (for example, sunlight
reflected off the vehicle body) is picked
up by the camera, a smear effect
* pecu-
liar to the camera may occur.
*: Smear effect—A phenomenon that occurs when a bright light (for example,
sunlight reflected off the vehicle body)
is picked up by the camera; when trans-
mitted by the camera, the light source
appears to have a vertical streak above
and below it.
