■When the Stop & Start system is operating
● Keep the shift lever in N (manual transmission) and apply the brake pedal
or parking brake for safety while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Do not leave the vehicle while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Ensure that the engine is not stopped by the Stop & Start system while the
vehicle is in a poorly ventilated area. The engine may restart due to the
automatic engine start function, causing exhaust gases to collect and
enter the vehicle and resulting in death or a serious health hazard.
NOTICE
■ To ensure the system operates correctly
If any one of the following situations occurs, the Stop & Start system may
not operate correctly, thus, please have your vehicle checked by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆PCS (Pre-Crash Safety system) (if equipped)
 P. 2 2 7
◆Emergency brake signal
When the brakes are applied suddenly, the emergency flashers
automatically flash to alert the vehicle behind.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

more than 3 seconds while the vehicle is stopped.
The “TRC OFF” indicator and the VSC OFF indicator will come on.
Press the switch again to turn the systems back on.
On vehicles with pre-crash safety system, pre-crash brake assist and pre-
crash braking will also be disabled. The PCS warning light will come on.
( P. 233)
■ When the “TRC OFF” indicator comes on even if the VSC OFF switch
has not been pressed
TRC cannot be operated. Contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, 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 TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC 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.

It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.

WARNING
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
■ When the outside rear view mirror defoggers (if equipped) are on
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE

body is cool.
■ Automatic car washes
● Fold the mirrors and remove the antenna before washing the vehicle. Start
washing from the front of the vehicle. Make sure to re-install the antenna
and extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
● Rear spoiler (if equipped) may not be washable in some automatic car
washes. There may also be an increased risk of damage to vehicle.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity of
the windows and door borders, and high mounted stoplight.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ When using a car wash (vehicles with a smart entry & start system)
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position
2 m (6 ft.) or more separate from the vehicle while the vehicle is being
