When driving
■
Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the front turn signal lights
turn on automatically whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■ Headlight control sensor (vehicles with automatic light control system)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights automati-
cally turn off after 30 seconds when all doors are closed with the engine
switch turned to the ACC or LOCK position. (The lights turn off immedi-
ately if the button on the wireless remote control is pressed after all
doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically
with the engine switch turned to the ACC or LOCK position and the
driver’s door is opened.
Vehicles with automatic light control system: If any of the doors is kept open,
the lights automatically turn off after 20 minutes.
To turn the lights on again, turn the engine switch to the ON position, or turn
the headlight switch off once and then back to the or position.
■ Customization
●That can be configured at Toyota dealer (vehicles without multi-informa-
tion display)
Settings (automatic light off system) can be changed. (Customizable
features P. 684)
● It is possible to change the settings (vehicles with multi-information dis-
play) (Feature customization P. 206)
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.

228 2-4. Using other driving systems
■The Intuitive parking assist system can be operated when
●Front corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is approximate 6 mph
(10 km/h) or less.
● Back and rear corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R
■ Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a 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
ultrasonic waves.
• There is another vehicle equipped with intuitive 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 radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When the bumper is damaged.

5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the transmission shift lever
● Whether the driver and front passenger wore seat belts or not
● Driver’s seat position
● SRS airbag deployment data
● SRS airbag system diagnostic data
● Front passenger’s occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.
