WARNING

■

When starting the hybrid system

Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.

■

Stopping the hybrid system in an emergency

●

If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or
press it briefly 3 times or more in succession. (



P. 665)

However, do not touch the power switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull
over and stop the vehicle as soon as it is safe to do so.

●

If the power switch is operated while the vehicle is running, a warning
message will be shown on the multi-information display and a buzzer
sounds.

●

When restarting the hybrid system after an emergency shutdown while
driving, press the power switch. When restarting the hybrid system after
stopping the vehicle, change the shift position to P and then press the
power switch.

■

When parking

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

●

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 operating 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 operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle.

For the shift positions

●

When the power switch is off, the shift position cannot be changed.

●

When the power switch is in ON mode (the hybrid system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift lever is shifted to D or R and held in that posi-
tion.

●

When the “READY” indicator is on, the shift position can be changed from P
to D, N or R.

●

When the “READY” indicator is flashing, the shift position cannot be
changed from P to another position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and then
operate the shift lever again.

●

The shift position can only be changed to B directly from D.

In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.

●

Situations where the shifting operation will be disabled:
• When an attempt is made to change the shift position from P to another

position by moving the shift lever without depressing the brake pedal.

• When an attempt is made to change the shift position from P or N to B by

moving the shift lever.

• When an attempt is made to change the shift position from P to another

position by moving the shift lever while the charging cable is connected to
the vehicle.

●

Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.

*

1

• When an attempt is made to select the R position by moving the shift

lever when the vehicle is moving forward.

*

2

• When an attempt is made to select the D position by moving the shift

lever when the vehicle is moving in reverse.

*

3

• When an attempt is made to change the shift position from R to B by

moving the shift lever.

speeds.

*

2

: Shift position may be changed to R when driving at low speeds.

*

3

: Shift position may be changed to D when driving at low speeds.

●

If N is selected while driving at a certain speed, even if the shift lever is not
held in the N position, the shift position changes to N. In this situation, the
buzzer sounds and a confirmation message is displayed on the multi-infor-
mation display to inform the driver that the shift position has changed to N.

WARNING

■

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.

●

After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

●

Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.

●

Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.

●

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

●

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

●

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

■

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

●

Securely insert the fuel nozzle into the fuel filler neck.

●

Stop filling the tank after the fuel nozzle automatically clicks off.

●

Do not top off the fuel tank.

when the vehicle is in the sun or
in an extremely cold environ-
ment

If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.

If a sunshade was used when the vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature of the front camera to become
excessively high.

If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.

The area in front of the front

PCS (Pre-Collision System)

The system can detect the following:

●

Vehicles

●

Bicyclists

●

Pedestrians

The pre-collision system uses a radar sensor and front camera
to detect objects (



P. 384) in front of the vehicle. When the sys-

tem determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take eva-
sive action and the potential brake pressure is increased to help
the driver avoid the collision. If the system determines that the
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collision
or help reduce the impact of the collision.

The pre-collision system can be disabled/enabled and the warning
timing can be changed. (

WARNING

■

Limitations of the pre-collision system

●

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.

●

Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision:



P. 390

• Conditions under which the system may not operate properly:



P. 392

●

Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking function is operating, a large amount of
braking force will be applied.

●

If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.

●

The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.

●

In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.

●

If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

LTA (Lane Tracing Assist)

While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the current
lane or course

*

, and also can slightly operate the steering wheel to

help avoid deviation from the lane or course

*

. Also, while the dynamic

radar cruise control with full-speed range is operating, this system will
operate the steering wheel to maintain the vehicle’s lane position.
The LTA system recognizes white
(yellow) lane lines or a course

*

using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.

*

: Boundary between asphalt and the

side of the road, such as grass, soil,
or a curb

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.

●

Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.

●

When not using the LTA system, use the LTA switch to turn the system off.

■

Situations unsuitable for LTA system

In the following situations, use the LTA switch to turn the system off. Failure
to do so may lead to an accident, resulting in death or serious injury.

●

Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.

●

Vehicle is driven on a snow-covered road.

●

White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.

●

Vehicle is driven in a temporary lane or restricted lane due to construction
work.

●

■

Preventing LTA system malfunctions and operations performed by
mistake

●

Do not modify the headlights or place stickers, etc. on the surface of the
lights.

●

Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
