3-2. Opening, closing and locking the doors
●The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
● A sudden handle operation or a handle operation immediately after entering
the effective range may prevent the doors from being unlocked. Touch the
door unlock sensor and check that the doors are unlocked before pulling the
door handle again.
● Gripping the door handle when wearing a glove may not unlock the door.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
● The smart key system can be deactivated in advance. Ask your Toyota
dealer for details.
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The

The function will set to ON mode each time the engine switch is turned to
the “ON” position (vehicles without smart key system) or IGNITION ON
mode (vehicles with smart key system).
Pressing the button turns the function to OFF mode. (The indicator also
turns off.)
■ To prevent sensor error (vehicles with auto anti-glare inside rear view
mirror)

4-3. Operating the lights and wipers
■Headlight control sensor (if equipped)
■ Automatic light off system
When the headlights are on: The lights turn off 30 seconds after the engine
switch is turned to the “LOCK” position (vehicles without smart key system) or
off (vehicles with smart key system) and a door is opened and all of the doors
are closed. (The lights turn off immediately if on the key is pressed
while all the doors are locked.)
When only the tail lights are on: The lights turn off after the engine switch is
turned to the “LOCK” position (vehicles without smart key system) or off
(vehicles with smart key system) and the driver’s door is opened.
To turn the lights on again, turn the engine switch to the “ON” position (vehi-

■ Light reminder buzzer
Vehicles without smart key system
A buzzer sounds when the engine switch is turned to the “LOCK” position, the
key is removed and the driver’s door is opened while the lights are turned on.
Vehicles with smart key system
A buzzer sounds when the engine switch is turned off and the driver’s door is
opened while the lights are turned on.
■ Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 700)
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.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

the headlight switch in the
position.
The Automatic High Beam indica-
tor will come on when the head-
lights are turned on automatically
to indicate that the system is
active.
∗: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetlights, the lights of vehicles
ahead etc., and automatically turns the high beam on or off as
necessary.
WARNING
■ Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning the high beam on or off manually if
necessary.
■ To prevent incorrect operation of the Automatic High Beam system
Do not overload the vehicle.

■Camera sensor detection information
●The high beam may not be automatically turned off in the following situa-
tions:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
● The high beam may be turned off if a vehicle ahead that is using fog lights
without using the headlights is detected.
● House lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beam to switch to the low beams, or the low beams to
remain on.
● The following factors may affect the amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of vehicles ahe\
ad
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface
etc.)
• The number of passengers and amount of luggage
● The high beam may be turned on or off when the driver does not expect it.
● Bicycles or similar objects may not be detected.
● In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low beams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or are not aimed properly.
• When driving through an area of in termittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.

• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
■ Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in .
• The headlight switch lever is in high beam position. Turn the engine switch to IGNITION ON mode.
Within 5 seconds after , repeat pulling the headlight switch lever to the
original position then pushing it to the high beam position quickly 9 times,
then leave the lever in high beam position.
Automatic High Beam (headlights) may turn on even the vehicle is stopped.
■ If a warning message of the Auto matic High Beam is displayed
It may indicate a malfunction in the system. Contact your Toyota dealer.

Driving
The pre-collision system is equipp ed with a sophisticated computer
that will record cert ain data, such as:
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distanc e and relative speed between your
vehicle and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-colli-
sion braking function or the pre-collision brake assist function was
operating)
• The pre-collision system does not record conversations, sounds or
images of the inside of the vehicle.
● 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 recor ded 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 images can be erased using a specialized device. The
image recording function can be disabled. However, if the function
is disabled, data from when the pre-collisio n system operates will
not be available.
