■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. 44)
●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.

1-8. Safety information
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 correctly fixed in place, the child 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 sh oulder. 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 an accident or sudden
braking.
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child seat in different directions to be sure it is secure.
●Follow all installation instructions provid ed by the child restraint system manufac-
turer.
●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 or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child restraint on the front passen-
ger seat, move the seat as far back as possi-
ble. Failing to do so may result in death or
serious injury if the airbags deploy (inflate).

Before driving
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 a collision.
■To correctly attach a child restraint system to the anchorages
When using the lower anchorages, be sure that there are no foreign objects around
the anchorages and that the seat belt is not caught behind the child seat. Make sure
the child restraint system is securely at tached, or it may cause death or serious
injury to the child in the even t of a sudden stop or accident.

2-1. Driving procedures

When driving
CAUTION
■When taking a nap in the vehicle
Always turn the hybrid system off. 
Otherwise, you may accidentally move the shift lever or press the accelerator
pedal, which could cause an accident or fi re due to abnormal hybrid system over-
heating. Additionally, if the vehicle is park ed in a poorly ventilated area, exhaust
fumes may enter the vehicle and cause gas poisoning.
■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 the hybrid system is not operating. 
Each push on the pedal uses up yo ur reserved brake fluid pressure.
●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.

2-4. Using other driving systems
Example of follow-up cruising (when following a vehicle driving slower
than the set speed): When the speed is set to 62 mph (100 km/h) and
the v
ehicle ahead is driv ing at 50 mph (80 km/h)
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 ther e are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
6

2 mph (100 km/h) and the vehicle ahead driving at 50 mph (80 km/
h) is out of the lane
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.
■Dynamic radar cruise control warn ing lights, messages and buzzers
Warning lights, messages and buzzers are us ed to in
dicate a system malfunction or
to alert you to the need for caution while driving. ( P. 4 4 0 )
■The dynamic radar cruise can be set when
●The shift lever is in “D” or the “4”, “5” or “6” range of “S”.
●Vehicle speed is between approximately 27 mph (43 km/h) and 87 mph (139
km/h).
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed
r

esumes.

When driving
■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.
