WARNING

■

When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. (

P. 30)

■

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, 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.

●

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 the “AIR BAG OFF”
indicator  light  is  illuminated.  Failure  to
do  so  may  result  in  death  or  serious
injury if the airbags deploy (inflate).

WARNING

■

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 plate 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 been securely installed.

●

After securing a child restraint system, never adjust the seat.

●

Follow all installation instructions provided by the child restraint system
manufacturer.

●

When securing some types of child restraint systems in rear seats, it may
not be possible to properly use the seat belts in positions next to the child
restraint without interfering with it or affecting seat belt effectiveness. Be
sure your seat belt fits snugly across your shoulder and low on your hips. If
it does not, or if it interferes with the child restraint, move to a different
position. Failure to do so may result in death or serious injury.

■

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 sud-
den 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 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 sudden braking, sudden swerve or an accident.

1-1. For safe use

Exhaust gas precautions

Harmful substance to the human body is included in exhaust
gases if inhaled.

WARNING

Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.

■

Important points while driving

●

Keep the trunk lid closed.

●

If you smell exhaust gases in the vehicle even when the trunk lid is closed,
open the windows and have the vehicle inspected at your Toyota dealer as
soon as possible.

■

When parking

●

If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.

●

Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.

●

Do not leave the hybrid system running in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is running, exhaust gases may collect and enter the vehicle.

■

Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

Hybrid system features

Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.

1-2. Hybrid system

◆

When stopped/during start off

The gasoline engine stops

, when the vehicle is stopped. During

start off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine is
stopped

and the electric motor (traction motor) is used.

When the shift lever is in N, the hybrid battery (traction battery) is
not being charged.

: When the hybrid battery (traction battery) requires charging or the

engine is warming up, etc., the gasoline engine will not automatically
stop. (

P. 71)

◆

During normal driving

The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as nec-
essary.

◆

When accelerating sharply

When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline
engine via the electric motor (traction motor).

◆

When braking (regenerative braking)

The wheels operate the electric motor (traction motor) as a power
generator, and the hybrid battery (traction battery) is charged.

When driving with the gasoline engine stopped, a sound, which
changes in accordance with the driving speed, will be played in order
to warn people nearby of the vehicle’s approach. The sound will stop
when the vehicle speed exceeds approximately 15 mph (25 km/h).

■

Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).

●

The accelerator pedal is released while driving with the shift lever in D or S.

●

The brake pedal is depressed while driving with the shift lever in D or S.

■

Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:

●

During gasoline engine warm-up

●

During hybrid battery (traction battery) charging

●

When the temperature of the hybrid battery (traction battery) is high or low

●

When the heater is switched on

■

Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery (traction battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.

■

Charging the 12-volt battery
P. 487

■

After the 12-volt battery has discharged or when the terminal has been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact your
Toyota dealer.

The  EV  indicator  comes  on  when  the
vehicle  is  driven  using  only  the  electric
motor  (traction  motor)  or  the  gasoline
engine is stopped.

hybrid battery (traction battery), under the rear seats, when the hybrid sys-
tem is started or stopped.

●

Sounds from the hybrid system may be heard when the trunk lid is open.

●

Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.

●

Engine sounds may be heard when accelerating sharply.

●

Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.

●

Vibration may be felt when the gasoline engine starts or stops.

●

1-2. Hybrid system

There  is  an  air  intake  vent  under
the  right  side  of  the  rear  seat  for
the  purpose  of  cooling  the  hybrid
battery  (traction  battery).  If  the
vent becomes blocked, the hybrid
battery  (traction  battery)  may
overheat, leading to a reduction in
the  hybrid  battery  (traction  bat-
tery) output.

When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact your Toyota dealer.

A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. (

The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.

■

Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light (

P. 455) go off. If there is only a small amount of fuel, the

hybrid system may not be able to start. (The standard amount of fuel is about
2.3 gal. [8.8 L, 1.9 Imp. gal.] when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)

■

Electromagnetic waves

●

High voltage parts and cables on hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.

●

Your vehicle may cause sound interference in some third party-produced
radio parts.

■

Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

WARNING

■

High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.

●

Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.

●

The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the warning labels attached to the vehicle.

●

Do not touch the service plug located
under the right side of the rear seat. The
service plug is used only when the vehi-
cle is serviced and is subject to high
voltage.

■

Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:

●

Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.

●

Do not touch the high voltage parts, cables and connectors.

●

If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.

●

If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.

●

If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.

●

If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (

P. 448)

●

Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

●

If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount
of electrolyte from leaking out. However, any electrolyte that does leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.

WARNING

■

Hybrid battery (traction battery)

●

Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-

ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.

• The hybrid battery is intended to be used exclusively with your hybrid

vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.

When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be
aware of these dangers.

●

If  your  vehicle  is  disposed  of  without  the  hybrid  battery  having  been
removed, there is a danger of serious electric shock if high voltage parts,
cables  and  their  connectors  are  touched.  In  the  event  that  your  vehicle
must  be  disposed  of,  the  hybrid  battery  must  be  disposed  of  by  your
Toyota dealer or a qualified service shop. If the hybrid battery is not dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.
