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-
cle.
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 strap and
then allow it to retract slightly into
the ALR lock mode.
Lock mode allows the seat belt to
retract only.

■Laws and regulations pertaining to anchorages
Anchorages conform to FMVSS225 or CMVSS210.2. 
Child restraint systems conf orming to FMVSS213 or CMVSS213 specifications
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. 6 8 )
●ALR mode causes the belt to tighten only which could cause injury or discomfort
to the child.
●Do not allow the child to play with the seat belt or the child could be killed or seri-
ous injured.

CAUTION
■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 correctl y fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking or an accident.
●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 an accident or sudden braking.
●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.
●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
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child restraint system in different directions to be sure it is
secure.
●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 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 a collision.
■To correctly attach a child restraint system to the anchors
When using the lower 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 or accident.

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 venti-
lated 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 brake actuator does not operate, do not follow other vehicles closely and
avoid downhill or sharp turns that require making. 
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 turning the hybrid system off. 
Each push on the brake pedal uses up th e reserve for the power-assisted brakes.
●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.

Example of follow-up cruising 
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration 
When there are no longer vehicles driving slower than the set speed in
the lane ahead
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise cont rol is not possible, the display will
flash and buzzer will sound to alert th e driver. An example of this would
be if another driver cuts in front of you while you are following a vehicle.
Apply the brakes to ensure an appr opriate vehicle-to-vehicle distance.
■Warning lights and messages for dynamic radar cruise control
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( P. 5 0 2 )
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehic le control mode. Turn the system off by
pressing the “ON-OFF” button, and turn it on again.

■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* peculiar 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 transmitted by the
camera, the light source appears to have a
vertical streak above and below it.
