Operation of each component
●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.
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
●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.
●Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
*: This setting can be customized at your Toyota dealer.
■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. (P. 526)
●Setting the electronic key to battery-saving mode helps to reduce key bat-
tery depletion. (P. 150)
■To operate the system properly

2204-3. Operating the lights and wipers
■Headlight control sensor
■Automatic light off system
●When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after the power switch is turned to ACCESSORY mode or turned off
and a door is opened and closed. (The lights turn off immediately if on
the key is pressed twice after all the doors are closed.)
●When only the tail lights are on: The tail 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 the power switch to ON mode, or turn the light
switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.
■Light reminder buzzer (except when the light switch is in )
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.
■Windshield wiper linked headlight illumination
When driving during daytime with the headlight switch turned to , if the
windshield wipers are used, the headlights will turn on automatically after

5c005200580055000300590048004b004c0046004f00480011[ 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.

2224-3. Operating the lights and wipers
Push the lever away from you
with the headlight switch in the
or position.
Press the Automatic High
Beam switch.
The Automatic High Beam indica-
tor will come on when the system
is operating.
Automatic High Beam
The Automatic High Beam uses a camera sensor located behind
the upper portion of the windshield to assess the brightness of
the lights of vehicles ahead, streetlights, etc., and automatically
turns the high beams on or off as necessary.
WARNING
■Limitations of the Automatic High Beam
Do not overly rely on the Automatic High Beam. Always drive safely, taking
care to observe your surroundings and turning the high beams on or off
manually if necessary.
■To prevent incorrect operation of the Automatic High Beam system
Do not overload the vehicle.

■Conditions to turn the high beams on/off automatically
●When all of the following conditions are met, the high beams will be turned
on automatically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
●If any of the following conditions is met, the high beams will turn off automat-
ically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■Camera sensor detection information

• When the lights of vehicles ahead are not on
●The high beams may be turned off if a vehicle ahead that is using fog lights
without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs
and other reflective objects may cause the high beams to change to the low
beams, or the low beams to remain on.
●The following factors may affect the amount of time taken for the high
beams to turn on or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles
ahead
• 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

Driving
●In the following situations the system may not be able to correctly detect the
surrounding brightness level. This may cause the low beams to remain on
or the high beams to flash or dazzle pedestrians or vehicles ahead. In such
a case, it is necessary to manually switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms,
etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of headlights, tail
lights or fog lights
• When headlights or tail lights of vehicles ahead are turned off, dirty,
changing color, or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehi-
cle
• When driving through an area of intermittently 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 roads, etc.)
• When frequently and repeatedly taking curves or driving on a winding
road
• When there is a highly reflective object ahead of the vehicle, such as a
sign or mirror
• When the back of a preceding vehicle is highly reflective, such as a con-
tainer on a truck
• When the vehicle's headlights are damaged or dirty, or are not aimed
properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed,
etc.
• When the headlights are changed between the high beams and low
beams repeatedly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling
pedestrians or other drivers
