■Engine switch illumination
According to the situation, the
engine switch illumi nation operates
as follows:
●When a door is opened, or the
engine switch mode is changed
from ACC or ON to off, the engine
switch illumination comes on.
●When depressing the brake pedal
with carrying the electronic key on
your person, the engine switch
illumination blinks.
●When the engine switch mode is
in ACC or ON, the engine switch
illumination is constantly illumi-
nated.
■If the engine does not start
●The engine immobilizer system
may not have been deactivated.
(  P. 7 7 )
Contact your Toyota dealer.
●If a message related to start-up is
shown on the multi-information
display, read the message and fol-
low the instructions.

■Operation of the engine switch
●If the switch is not pressed shortly
and firmly, the engine switch
mode may not change or the
engine may not start.
●If attempting to restart the engine
immediately after turning the
engine switch off, the engine may
not start in some cases. After turn-
ing the engine switch off, please
wait a few seconds before restart-

■Customization
If the smart key system has been
deactivated in a customized setting,
refer to P.381.
WARNING
■When starting the engine
Always start the engine while sit-
ting in the driver’s seat. Do not
depress the accelerator pedal
while starting the engine under
any circumstances.
Doing so may cause an accident
resulting in death o r serious injury.
NOTICE
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to
start or stalls frequently, have
your vehicle checked by your
Toyota dealer immediately.

Driving
1Stop the vehicle completely.
2 Set the parking brake
( 168), and shift the shift
lever to P.
Check the parking brake indicator
is illuminated.
3 Press the engine switch
shortly and firmly.
The engine will stop, and the meter
display will be extinguished.
4Release the brake pedal and
check that “ACCESSORY” or
“IGNITION ON” is not shown
on the multi-information dis-
p l a y.
■Automatic engine shut off fea-
ture
●The vehicle is equipped with a
feature that automatically shuts off
the engine when the shift lever is
in P with the engine running for an
extended period.
●The engine will automatically shut
off after approximately 1 hour if it
has been left running while the
shift lever is in P.
●The timer for the automatic engine
shut off feature will reset if the
brake pedal is depre ssed or if the
shift lever is in a position other than P.
●After the vehicle
is parked, if the
door is locked with the door lock
switch ( P.115) from the inside or
the mechanical key (P.381) from
the outside, the automatic engine
shut off feature will be disabled.
The timer for the automatic engine
shut off feature will be re-enabled
if the driver’s door is opened.NOTICE
■Symptoms indicating a mal-
function with the engine
switch
If the engine switch seems to be
operating somewh at differently
than usual, such as the switch
sticking slightly, there may be a
malfunction. Contact your Toyota
dealer immediately.
Stopping the engine
WARNING
■Stopping the engine in an
emergency
●If you want to stop the engine in
an emergency while driving the
vehicle, press and hold the
engine switch for more than 2
seconds, or press it briefly 3
times or more in succession.
(  P.348)
However, do not touch the
engine switch while driving
except in an emergency. Turn-
ing the engine off while driving
will not cause loss of steering or
braking control, but the power
assist to these systems will be
lost. This will make it more diffi-
cult to steer and brake, so you
should pull over and stop the
vehicle as soon as it is safe to
do so.
●If the engine switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-information display
and a buzzer sounds.
●To restart the engine after per-
forming an emergency shut-
down, shift the shift lever to N
and then press the engine
switch.

WARNING
■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 venti-
lated area or a closed area,
such as a garage, stop the
engine.
●Do not leave the vehicle with
the engine running 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 engine running
in an area with snow build-up,
or where it is snowing. If snow-
banks build up around the vehi-
cle while the engine is running,
exhaust gases may collect and
enter the vehicle.

turned to ACC, not to off.
*2: ACC mode can be enabled/dis-abled on the customize menu.
( P.412)
■Auto power off function
If the vehicle is left in ACC or ON
(the engine is not running) for more
than 20 minutes with the shift lever
in P, the engine switch will automati-
cally turn to OFF.
However, this function cannot
entirely prevent battery discharge.
Do not leave the vehicle with the
engine switch in ACC or ON for long
periods of time when the engine is
not running.
■When ACC customization is in
off
With the engine switch is turned off,
the multimedia system can still be
used for a certain time until the bat-
tery saving function starts operating.
If the engine is stopped with the
shift lever in a position other
than P, the engine switch will not
be turned off. Perform the fol-
lowing procedure to turn the
switch off:
1Check that the parking brake
is set.
2 Shift the shift lever to P.
3 Check that “IGNITION ON” is
displayed on the multi-infor-
mation display and press the
engine switch shortly and
firmly.
4 Check that “ACCESSORY”
or “IGNITION ON” on the
multi-information display are
off.
NOTICE
■To prevent battery discharge
●Do not leave the engine switch
in ACC or ON for long periods of
time without the engine running.
●If “ACCESSORY” or “IGNITION
ON” is displayed on the
multi-informatio n display, the
engine switch is not off. Exit the
vehicle after turning the engine
switch off.
When stopping the engine
with the shift lever in a
position other than P
NOTICE
■To prevent battery discharge
Do not stop the engine when the
shift lever is in a position other
than P. If the engine is stopped in
another shift lever position, the
engine switch will not be turned
off and remained to ON. If the
vehicle is left in ON, battery dis-
charge may occur.

1604-2. Driving procedures
*: To improve fuel efficiency and reduce noise, shift the shift lever
to D for normal driving.
■To protect the continuously
variable transmission
If the continuously variable trans-
mission fluid temperature is high,
“Transmission Oil Temp High Stop in
a Safe Place and See Owner’s
Manual” will be displayed on the
multi-information display and the
vehicle will go into transmission pro-
tection mode automatically. Have
the vehicle inspected by your Toyota dealer.
■When driving with the dynamic
radar cruise control activated
Even when switching the driving
mode to sport mode with the intent
of enabling engine braking, engine
braking will not occur because
dynamic radar cruise control will not
be canceled. ( P.247)
■Restraining sudden start
(Drive-Start Control)

■G AI-SHIFT
G AI-SHIFT automat ically selects a
suitable gear for sporty driving
according to driver’s input and driv-
ing conditions. G AI-SHIFT operates
automatically when th e shift lever is
in D and sport mode is selected for
the driving mode. (Selecting normal
mode or shifting the shift lever to the
B position cancels this function.)
■After recharging/reconnecting

■Continuously variable transmis-
sion fail-safe control
The system detects malfunctioning
parts targeted (all of the solenoids
that perform the shifting function) by
the On-Board Diagnostics, and per-
forms fail-safe mechanisms, such
as restricting the shifting function or
transmission ratio control.
In this event, the malfunction indica-
tor lamp turns on.
