HIGHLANDER_HV_U (OM48F12U)
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)
• Image information from the camera sensor (available only when the pre-collision braking function or t he pre-collision brake assist func-
tion 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 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)
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 possibi lity 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. 272)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. See the following table for
details.

Driving
HIGHLANDER_HV_U (OM48F12U)• When driving in inclement weather such as heavy rain, fog, snow or a
sandstorm
• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes sud- denly, such as at the entrance or exit of a tunnel
• 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 hybrid system 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 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
• If the radar sensor or camera sensor is misaligned
● 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 front of the vehicle is raised or
lowered

If the PCS (Pre-Collisi on System) warning light flashes and a warning
message is displayed on the multi-information display
The pre-collision system may be tem porarily 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.
• When the part of the windshield in front of the camera sensor is fogged up or covered with condensation or ice
(Defogging the windshield: →P. 436)
• 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 (Pre-Collision System) 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. 331), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS (Pre-Collision System) warning light will turn on and “VSC Turned
Off Pre-Collision Brake System Unavailable” will be displayed on the multi-
information display.

HIGHLANDER_HV_U (OM48F12U)
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 320 ft. (100 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 switch.
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.

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. 299) 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
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely
high ground clearance

Conditions under which the vehicle -to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
●
When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable
