■Daytime running light system
To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the hybrid system is
started and the parking brake is released with the headlight switch off or in
the position. (Illuminate brighter than the front position lights.) Daytime
running lights are not designed for use at night.
■ Headlight control sensor (if equipped)
■ Automatic light off system
When the light switch is in or : The headlights and front fog lights
turn off automatically if the power switch is turned off.
When the light switch is in : All lights turn off automatically if the power
switch is turned off.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .
■ Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCES-
SORY mode and the driver's door is opened while the lights are turned on.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

◆Pre-crash warning
When the system determines
that the possib ility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the sy stem applies greater braking force
in relation to how strongly the brake pedal is depressed.
◆Pre-crash braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the sy stem warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically appli ed to help avoid the collision or
reduce the collision speed.
PCS (Pre-Crash Safety system)
: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehi cle. When the system determines
that the possibility of a frontal co llision with a vehicle is high, a
warning operates to urge the driver to take evasive 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 a vehicle is extremely high, the brakes are
automatically applied to help av oid the collision or help reduce
the impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. ( P. 255)

Driving
• If the wheels are misaligned
• If a wiper blade is blocking the front sensor
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on roads with sharp bends or uneven surfaces
• When a preceding vehicle is a poor reflector of laser
● In some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
• If your vehicle is skidding
• When the front part of the vehicle is
raised or lowered
• When the sensor is misaligned due to
a strong impact being applied to the
sensor, etc.

■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi -information display
The pre-crash safety system may be tem porarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will turn off, the message will
disappear and the system will become operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 384)
• When driving in conditions where the front sensor cannot detect an
object, such as in the dark (at night on a road without street lights or other
lights, etc.), when bright light is shining into the sensor, or in snow or fog.
• When the front sensor or the area around ei ther sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sensor is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.
■ If VSC is disabled
● If TRC and VSC are disabled (P. 307), the pre-crash safety brake assist
and pre-crash safety braking functions are also disabled. However, the pre-
crash safety warning function will still operate.
● The PCS warning light illuminates and “Pre-Crash Brake is disabled due to
VSC OFF.” is displayed on the multi-information display.

Driving
■The Toyota parking assist-sensor can be operated when
The power switch is in ON mode.
● Front sensors:
• The shift position is shifted to a position other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
(At any speed when the shift position is in R)
● Rear sensors:
The shift position is in R.
■ Sensor detection information
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelet is installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
● The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle

■ Toyota parking assist-sensor operation during Simple-IPA operation
Even if the Toyota parking assist-sensor is turned off while Simple-IPA is acti-
vated, the Toyota parking assist-sensor will keep operating. In this case,
when Simple-IPA operation is complete or canceled, the Toyota parking
assist-sensor will be deactivated.
■ When the cabin temperature is high
The sensors may not work properly when the cabin temperature is high due
to parking the vehicle in the sun. Use Simple-IPA after the cabin cools down.
■ Sensors used by Simple-IPA
 P. 284
■ Initializing Simple-IPA
Within 15 seconds of turning the Simple-IPA switch on, turn the steering
wheel all the way to the left or right and then to the opposite side.
When the parking space detection screen is displayed, the initialization is
complete.
If pressing the Simple-IPA switch again still shows “IPA not available, stop the
vehicle, turn wheel from left end to ri ght end.” on the multi-information display,
the initialization has failed. Have the vehicle inspected at any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
WARNING
■ Cautions regarding the use of Simple-IPA
● Never depend on the Simple-IPA entirely when parking. The driver is
responsible for safety. Use caution, just as you would when parking any
vehicle.
● Back up slowly, using the brake pedal to control the vehicle's speed.
● If it seems likely to hit nearby vehicles, obstacles, or people, depress the
brake pedal to stop the vehicle, and the disable the system.
