■To prevent sensor error (vehicles with an auto anti-glare inside rear view
mirror)
Indicator
To ensure that the sensors operate prop-
erly, do not touch or cover them.
WARNING
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident,
resulting in death or serious injury.

With the headlights on, push
the lever away from you to turn
on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams with the headlights on or off.
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the engine is
started and the parking brake is released with the headlight switch in the
“ ”, “ ”, or “AUTO” position. (Illuminate darker than headlight low
beams.
*) 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.
*: Vehicles with daytime running lights that are integrated into the head-
lights
●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.

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.

COROLLA_TMMMS_TMMC_U (OM02494U)■Battery-saving function
In the following conditions, the headlights and the other remaining lights will
go off automatically after 20 minutes in order to prevent the vehicle battery
from being discharged:
●The headlights and/or tail lights are on.
●Vehicles without a smart key system: The engine switch is in the “ACC” or
“LOCK” position.
●Vehicles with a smart key system: The engine switch is turned to ACCES-
SORY mode or turned off.
This function will be canceled in any of the following situations:
●Vehicles without a smart key system: When the engine switch is turned to
the “ON” position.
●Vehicles with a smart key system: When the engine switch is turned to IGNI-
TION ON mode.
●When the light switch is operated
●When the door or trunk is opened or closed
■Customization
Settings (e.g. light sensor sensitivity) can be changed.

2004-3. Operating the lights and wipers
COROLLA_TMMMS_TMMC_U (OM02494U)
Push the lever away from you with
the headlight switch in the
position.
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
●The high beams may not be automatically turned off in the following situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• 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
• The condition of the road (gradient, curve, condition of the road surface,
etc.)
• The number of passengers and amount of luggage in the vehicle
●The high beams may turn on or off unexpectedly.
●Bicycles or similar vehicles may not be detected.
●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.

2104-5. Using the driving support systems
COROLLA_TMMMS_TMMC_U (OM02494U)
The pre-collision system is equipped with a sophisticated computer
that will record certain data, such as:
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your
vehicle and the vehicle ahead or other objects)
• Image information from the camera sensor (available only when the
pre-collision braking function was operating)
The pre-collision system does not record conversations or other
sounds and does not record 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 recorded 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.
