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.

*

1

: Shift  position  may  be  changed  to  P  when  driving  at  extremely  low

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.

Reverse warning buzzer

When  shifting  into  R,  a  buzzer  will  sound  to  inform  the  driver  that  the  shift
position is in R.

Restraining sudden start (Drive-Start Control)

P. 322

Automatic P position selection function

If the power switch is on and the shift position is not already P, completely
stopping the vehicle and pressing the power switch causes the shift position
to automatically switch to P and the power switch to turn off.

*

The shift position may also automatically switch to P if one of the following
conditions is detected while the vehicle is stopped by dynamic radar cruise
control with full-speed range.
• Driver’s seat belt is not fastened
• Driver’s door is opened
• Approximately 3 minutes elapse after the vehicle stopped

*

: If the power switch is pressed when driving at very low speeds (for exam-

ple,  just  before  the  vehicle  stops),  the  shift  position  may  automatically
switch to P. Press the power switch after completely stopping the vehicle to
prevent unexpected sudden stopping of the vehicle.

If the shift position cannot be shifted from P

There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (

P. 715)

About engine braking

When shift position B is selected, releasing the accelerator pedal will apply
engine braking.

When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.

The vehicle can be accelerated even when shift position B is selected.

If  the  vehicle  is  driven  continuously  in  the  B  position,  fuel  efficiency  will
become low. Usually, select the D position.

When  a  message  related  to  shift  operations  is  displayed  on  the  multi-
information display

When the shift position does not switch due to a mistaken operation, system
conditions, etc., or when the attempted shift operation is invalid, a message
indicating the correct operation or the reason why switching cannot be per-
formed is shown on the multi-information display. In these cases, follow the
instructions and retry the operation.

Customization

Settings (e.g. reverse warning buzzer) can be changed. 
(Customizable features: 

P. 753)

WARNING

When driving on slippery road surfaces

Do not accelerate or shift the shift position suddenly. 
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

Shift lever and P position switch

Do not remove the shift lever knob or use anything but a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever. 
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.

Do not press the P position switch while the vehicle is moving.
If  the  P  position  switch  is  pressed  when  driving  at  very  low  speeds  (for
example,  just  before  the  vehicle  stops),  the  vehicle  may  stop  suddenly
when the shift position switches to P, which could lead to an accident.

In order to prevent the shift position from accidentally being changed, do
not touch the shift lever or P position switch when not using them.

*

: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the park-
ing brake is set again.

For  the  U.S.A.:  Daytime  running  lights  can  be  turned  off  by  operating  the
switch.

Compared  to  turning  on  the  headlights,  the  daytime  running  light  system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.

High beam automatic turning on or off conditions

When all of the following conditions are fulfilled, the high beam will be auto-
matically turned on (after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.

If any of the following conditions are fulfilled, the high beam will be automat-
ically turned off:
• Vehicle speed drops below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.

The  high  beam  may  not be  automatically turned  off in  the  following  situa-
tions:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road

dividers or roadside trees

• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead vehicles have no lights

The high beam may be turned off if a vehicle ahead that is using fog lights
without using the headlights is detected.

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.

If the message does not disappear, contact your Toyota dealer.

• When the temperature around the radar sensor is outside of the opera-

tional range, such as when the vehicle is in the sun or in an extremely
cold environment

• When the front camera cannot detect objects in front of the vehicle, such

as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera

Situation

Actions

When the area around a sensor
is  covered  with  dirt,  moisture
(fogged  up,  covered  with  con-
densation,  ice,  etc.),  or  other
foreign matter

To clean the part of the windshield in front
of  the  front  camera,  use  the  windshield
wipers or the windshield defogger of the
air conditioning system (

P. 515, 527).

When  the  temperature  around
the  front  camera  is  outside  of
the  operational  range,  such  as
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
camera  is  obstructed,  such  as
when  the  hood  is  open  or  a
sticker is attached to the part of
the  windshield  in  front  of  the
front camera.

Close  the  hood,  remove the sticker, etc.
to clear the obstruction.

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. (

Pre-collision warning

When  the  system  determines
that  the  possibility  of  a  frontal

Pre-collision brake assist

When  the  system  determines  that  the  possibility  of  a  frontal  colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.

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.
