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.
(Customizable features: →P. 568)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

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.

COROLLA_TMMMS_TMMC_U (OM02494U)
■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.

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.

an accident resulting in death or serious injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets,
snow, etc., clear the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces-
sary to use the windshield wipers to remove water droplets, etc. from
the area of the windshield in front of the camera sensor.
• If the inner side of the windshield where the camera sensor is installed
is dirty, contact your Toyota dealer.
●If the part of the windshield in front of the camera sensor is fogged up or
covered with condensation or ice, use the windshield defogger to remove
the fog, condensation or ice. (→P. 372, 380)
●If water droplets cannot be properly removed from the area of the wind-
shield in front of the camera sensor by the windshield wipers, replace the
wiper insert or wiper blade.
If the wiper inserts or wiper blades need to be replaced, contact your
Toyota dealer.
●Do not attach window tinting to the windshield.
●Replace the windshield if it is damaged or cracked.
If the windshield needs to be replaced, contact your Toyota dealer.
●Do not get the camera sensor wet.
●Do not allow bright lights to shine into the camera sensor.

PCS (Pre-Collision System)
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 driver 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 to help avoid the collision or help reduce the
impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. (→P. 220)
*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.
