■The meters and display illuminate when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
■When disconnecting and reconnecting battery terminals
The following information data will be reset:
●Average fuel consumption
●Driving range
●Average vehicle speed
CAUTION
■The display at low temperatures
Allow the interior of the vehicle to warm up before using the display. At
extremely low temperatures, the display monitor may respond slowly, and
display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
■Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
●The engine may be overheating if the high engine coolant temperature
warning light comes on. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 537)

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
●Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
●Vehicles with an automatic transmission or continuously variable transmis-
sion: Always apply the parking brake, shift the shift lever to P, stop the
engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
Vehicles with a manual transmission: Always apply the parking brake,
stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
●Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

P. 1 1 6
■If the engine does not start
●The engine immobilizer system may not have been deactivated. (P. 66)
Contact your Toyota dealer.
●Vehicles with a continuously variable transmission: Check that the shift lever
is securely set in P. The engine may not start if the shift lever is displaced
out of P.
Vehicles without a multi-information display
The smart key system indicator light (green) will flash quickly.
Vehicles with a multi-information display
“SHIFT TO P POSITION TO START” will be displayed on the multi-informa-
tion display.
■Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■When the steering lock cannot be released
Vehicles with a manual transmission: Press the engine switch while turning
the steering wheel left and right.
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning. Vehicles without a multi-information dis-
play: The smart key system indicator light
(green) will flash quickly.
Vehicles with a multi-information display:
“STEERING LOCK ACTIVE” will be dis-
played on the multi-information display.
Vehicles with a continuously variable
transmission: Check that the shift lever is
set in P. Press the engine switch while
turning the steering wheel left and right.

■Turning off both TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The “TRAC OFF” indicator light and VSC OFF indicator light will come on.
Press again to turn the systems back on.
■When the “TRAC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed
TRAC/TRC cannot be operated. Contact your Toyota dealer.
■Sounds and vibrations caused by the ABS, brake assist, TRAC and VSC
systems
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate
that a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●Vehicles without a smart key system: When the engine switch is turned to
the “LOCK” position
Vehicles with a smart key system: When the engine switch is turned off
●If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.

CAUTION
■Burns
●Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
●Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
●Do not use seat heater more than necessary. Doing so may cause minor
burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■To prevent battery discharge
Turn the seat heaters off when the engine is not running.
