■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically (at a reduced intensity)
whenever the engine is started and the parking brake is released. Daytime
running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
■ Automatic light off system
●When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch has been
switched to ACCESSORY or OFF mode.
● When only the tail lights are on: The tail lights turn off automatically if the
engine switch is switched to ACCESSORY or OFF mode and driver’s door
is opened.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or
turn the light switch off once and then back to the or position.
■ Automatic headlight leveling system
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.
■ Welcome lighting
If the headlight switch is turned to and the surrounding area is dark,
unlocking the doors using the smart key system or wireless remote control
will turn the parking lights and tail lights on automatically.
■ If the automatic headlight level ing system warning light flashes
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Light reminder buzzer
A buzzer sounds when the engine switch is turned to ACCESSORY or OFF
mode and the driver’ door is opened while the tail 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.

Driving
The pre-collision system is equipp ed with a sophisticated computer
that will record certain data, such as: • How far (if at all) the driver was depressing the accelerator and/or brake pedal
• Vehicle speed
• Operation status of the pr e-collision system functions
• Information (such as the distanc e and relative speed between your
vehicle and the vehicle ahead or other objects)
Additionally, if the pre-collision braking function is operating, image
information from the camera sensor will al so be recorded. The pre-
collision system does not record c onversations, sounds or pictures.
● Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the reco rded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Recorded image information can be erased using a specialized
device.
The image information recording function can be disabled. How-
ever, if the function is disabled, data from when the pre-collision
system operates will not be available.

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines
that the possibility 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-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies gr eater braking force in relation to
how strongly the brake pedal is depressed.
: If equipped
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians
*1 in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the dr iver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied
*2 to help avoid the collision or help reduce the
impact to the vehicle occupants and the vehicle in the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( P. 237)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact your Toyota dealer for
details.
*2: Depending on the region in which the vehicle was sold, the pre-collisionbraking function (automatic braking function) may not be available. Con-
tact your Toyota dealer for details.

• When a very bright light, such as the sun or the headlights of oncoming
traffic, shines directly into the camera sensor
• When the surrounding area is dim, such as at dawn or dusk, or while at night or in a tunnel
• After the engine has started the vehicle has not been driven for a certain amount of time
• While making a left/right turn and for a few seconds after making a left/
right turn
• While driving on a curve and for a few seconds after driving on a curve
• If your vehicle is skidding
• If the front of the vehicle is raised or lowered, such as when the road sur- face is uneven or undulating
• If the wheels are misaligned
• If a wiper blade is blocking the camera sensor
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill
● 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 the PCS warning light flashes a nd a warning message is displayed on
the multi-information display
The pre-collision system may be temporarily 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 radar sensor or camera sensor or the area around either sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around either sen- sor is cold, such as in an extremely cold environment
• When the radar sensor or front grille emblem is dirty or covered with
snow, etc.
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or the warning message does not
disappear, the system may be malfunctioning. Have the vehicle inspected
by your Toyota dealer immediately.
■ If VSC is disabled
●If VSC is disabled ( P. 359), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on a nd “VSC Turned Off Pre-collision Brake

4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 400 ft. (120 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

■Automatic cancelation of co nstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
● Active TRAC is activated for a period of time.
● When the VSC or Active TRAC system is turned off by pressing the VSC
OFF switch.
● Pre-collision braking is activated.
If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
■ Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning ( P. 264) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
