the hybrid system. However, if the

electronic key is carried inside the

vehicle and the doors are locked

(P.187), the hybrid system can

be started.

The system may be malfunctioning.

Have the vehicle inspected by your

Toyota dealer immediately.

■If the “READY” indicator does

not come on

In the event that the “READY” indi-

cator does not come on even after

performing the proper procedures

for starting the vehicle, contact your

Toyota dealer immediately.

●When starting the hybrid system,

the flashing time of the “READY”

indicator may be long. Leave the

vehicle as it is until the “READY”

5 Release the brake pedal and

check that “ACCESSORY” or

“POWER ON” is not shown

on the meter.

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.

■When the shift control system

malfunctions

If the shift control system is malfunc-

tioning, when attempting to turn the

power switch off, it may not be able

to be turned off. In this situation, it

may be possible to turn the power

switch off by applying the parking

brake and then operating the power

switch.

NOTICE

■When starting the hybrid sys-

tem

If the hybrid system becomes diffi-

cult to start, have your vehicle

checked by your Toyota dealer

immediately.

If there is a malfunction in the sys-

tem, have the vehicle inspected by

your Toyota dealer immediately.

■Automatic hybrid system shut

off feature

If the power switch seems to be

operating somewhat differently

than usual, such as the switch

sticking slightly, there may be a

malfunction. Contact your Toyota

dealer immediately.

●The vehicle is equipped with a

feature that automatically shuts off

the hybrid system when the shift

position is in P with the hybrid sys-

tem operating for an extended

period.

●The hybrid system will automati-

cally shut off after approximately 1

hour if it has been left operating

while the shift position is in P.

Stopping the hybrid sys-

tem

1 Stop the vehicle completely.

●The timer for the automatic hybrid

system shut off feature will reset if

the brake pedal is depressed or if

the shift position is in a position

other than P.

2 If the parking brake is in man-

ual mode, set the parking

brake. (P.263)

●After the vehicle is parked, if the

door is locked with the door lock

switch (P.187) from the inside

or the mechanical key (P.587)

from the outside, the automatic

hybrid system shut off feature will

be disabled. The timer for the

automatic hybrid system shut off

feature will be re-enabled if the

driver’s door is opened.

WARNING

■When parking

Exhaust gases include harmful

carbon monoxide (CO), which is

colorless and odorless. Observe

the following precautions.

■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 suc-

cession. (P.547)

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.

However, do not touch the

power switch while driving

except in an emergency. Turn-

ing the hybrid system off while

driving will not cause loss of

steering or braking control.

However, power assist for the

steering wheel may be lost mak-

ing it difficult to steer smoothly

before stopping the vehicle

depending on the remaining

charge in the 12-volt battery or

usage conditions. In this situa-

tion, you should pull over and

stop the vehicle as soon as it is

safe to do so.

●If the vehicle is in a poorly venti-

lated 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 sys-

tem is operating, exhaust gases

may collect and enter the vehi-

cle.

●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 sys-

tem after an emergency shut-

down, shift the shift position to

N and press the power switch

shortly and firmly.

Changing power switch

modes

Modes can be changed by

pressing the power switch with

the brake pedal released. (The

mode changes each time the

switch is pressed.)

OFF.

●If the 12-volt battery is low with the

shift position is in P and the power

switch is in ACC or ON (the hybrid

system is not operating), a buzzer

1 Operate the shift lever and

change the shift position to N

when the hybrid system is

operating.

Regeneration Boost

When the shift position is shifted

to B, the Regeneration Boost

operates and control of acceler-

ation and deceleration is per-

formed with the operation of the

accelerator pedal only, reduc-

ing the frequency of changing

from the accelerator pedal to

depress the brake pedal. The

deceleration when the accelera-

tor pedal is released can be

selected, and smooth decelera-

tion is enabled by releasing the

accelerator pedal slowly without

completely removing your foot.

2 Return the shift lever to its

regular position ( ).

3 Operate the shift lever to N

and hold it there until the

buzzer sounds.

4 Press the power switch within

5 seconds after the buzzer

sounds.

Always perform the operation

with the hybrid system

started.

If “Deceleration Memory” is

switched to “OFF”, the regenerative

braking force will return to “Low”
