Airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants. Driver’s knee airbag

Headlight control sensor (if equipped)
Automatic light off system (if equipped)
When the light switch is in
or : The headlights and front fog
lights turn off automatically if the “POWER” switch is turned to ACCES-
SORY mode or turned off.
When the light switch is in : The headlights and all lights turn off
automatically if the “POWER” switch is turned to ACCESSORY mode or
turned off and the driver's door is opened.
To turn the lights on again, turn to ON mode, or turn the light switch off once
and then back to
or .
Light reminder buzzer (if equipped)
A buzzer sounds when the “POWER” switch is turned off or to ACCESSORY
mode and the driver's door is opened while the lights are turned on.
Automatic headlight leveling system (vehicles with discharge head-
lights)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
Customization that can be configured at any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional
Settings of the light sensor sensitivity can be changed.
(Customizable features P. 506)
Headlight control sensor is located on the
driver's side.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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.

Wash/wipe operation
Wipers operate automatically.
Rain-sensing windshield wipers
With “AUTO” selected, the wipers will operate automatically when
the sensor detects falling rain. The system automatically adjusts
wiper timing in accordance with rain volume and vehicle speed.

The windshield wipers and washer can be operated when
The “POWER” switch is in ON mode.
Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation varies
depending on vehicle speed when the washer is being used (delay until drip
prevention wiper sweep occurs).
Sensor sensitivity (high)
Sensor sensitivity (low)
Wash/wipe operation
Wipers operate automatically.
(After operating several times,
the wipers operate one more
time after a short delay to pre-
vent dripping.)
With the headlight cleaner and
discharge headlights: If the
headlights are on, the head-
light cleaners will operate
once. (P. 218)

When driving

Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper switch is turned to the “AUTO” position while the “POWER”
switch is in ON mode, the wiper will operate once to show that “AUTO”
mode is activated.
If the temperature of the raindrop sensor is 90C (194F) or higher, or
-15C (5F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and if there is washer fluid in
the windshield washer fluid reservoir.
CAUTION
Caution regarding the use of windshield wipers in “AUTO” mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers or anything else do not become caught in the windshield wipers.
The sensor judges the amount of rain-
drops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc.
are present on the windshield.

Toyota parking assist-sensor
: If equipped
Toyota parking assist-sensor uses sensors in the corners and rear of
the vehicle to detect the distance between the vehicle and any obsta-
cles, and informs the driver of this distance using the warning
beeps.
Sensor types
Rear corner sensors
Back sensors
Toyota parking assist-sensor switch
On/off
To turn the system on, press
the switch. The indicator light
comes on to inform the driver
that the system is operational.
To turn the system off, press
the switch again.

Approx. 50 cm (1.6 ft.)
Approx. 150 cm (4.9 ft.)
The detection area of the sensors
is shown to the left. If obstacles
move too close to the sensors,
they will not be detected.
The range of the sensors may
change depending on the shape
of the object etc.
The Toyota parking assist-sensor can be operated when
The “POWER” switch is in the ON mode, and 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. (Wiping the sensor will resolve
this problem.)
• The sensor is frozen. (Thawing the sensor will resolve this problem.)
• The sensor is covered in any way.
• In harsh sunlight or intense cold weather.
• When driving bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as
another vehicle’s horn, motorcycle engine noise, air braking sound
from heavy-duty vehicles, or another vehicle using the park assist sys-
tem.
• In heavy rain, or if water is splashed on the sensors.
• The vehicle is leaning considerably to one side.
• If a commercial fender pole or radio antenna is installed.
• If moving towards a high curb or a curb corner.
• If towing eyelet is installed on your vehicle.
• The bumper or sensor receives a strong impact.
• 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 sensors 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.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Low objects.
• Objects where the upper section projects out over the lower section.
