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 prec eding vehi-
cle
• When driving through an area of intermittently changing brightness and

■ Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are m et.
• The headlight switch is in the or position.
• The headlight switch lever is in the original position.

●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera- tional range, such as when the vehicle is in the sun or in an e xtremely
cold environment
• When the front camera cannot detect objects in front of the ve hicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, th e radar may
judge the surrounding environment cannot be properly recognized . In
that case, “Pre-Collision System Unavailable See Owner's Manual ” is dis-
played.

■Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on ( P. 1 0 1 )
of the multi-information display.
The system is automatically enabled each time the engine switch is
turned to IGNITION ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■Changing the pre-colli sion warning timing
The pre-collision warning timing can be changed on ( P. 1 0 1 )
of the multi-information display.
The warning timing setting is retained when the engine switch is turned
off. However, if the pre-collision system is disabled and re-en abled, the
operation timing will return to the default setting (middle).
If the pre-collision warning timing is changed, e mergency steering
assist timing will also b e changed accordingly.
If late is selected, emergency st eering assist would not operate in
case of an emergency.

night or in a tunnel, making a detectable object appear to be n early the
same color as its surroundings
• When driving in a place where the surrounding brightness changes sud- denly, such as at the entrance or exit of a tunnel
• After the engine 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 mak ing a left/
right turn

In the following situations, the RSA syst em will notify the driver.
● When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphas ized
and a buzzer will sound.
● When the RSA system recognizes a do not enter sign and deter-
mines that your vehicle has ent ered a no-entry area, the displayed
sign will flash and a buzzer will sound.
Depending on the situation, a not ification function may not operate
properly.
■ Setting procedure
Press / of the meter control switches, select .
Press / of the meter control switches, select .
Press of the meter control switch.
Each time is pressed, the function changes on/off.
■ Automatic turn-off of RSA sign display
In the following situations, a displayed speed limit sign and/o r do not enter
sign will stop being displayed automatically:
● No sign has been recognized for a certain distance.
● The road changes due to a left or right turn, etc.
In the following situations, stop and yield signs will stop bei ng displayed auto-
matically:
● The system determines that your vehicle has passed the sign.
● The road changes due to a left or right turn, etc.

■Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this do es not indicate a
malfunction.
● The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
● Dirt, snow, stickers, etc. are on the windshield near the front camera.
● In inclement weather such as heavy rain, fog, snow or sand storms
● Light from an oncoming vehicle, the sun, etc. enters the front camera.
● The sign is dirty, faded, tilted or bent.
● The contrast of electronic sign is low.
● All or part of the sign is hidden by the leaves of a tree, a pole, etc.
● The sign is only visible to the front camera for a short amount of time.
● The driving scene (turning, lane change, etc.) is judged incorr ectly.
● If a sign not appropriate for the currently traveled lane, but the sign exists
directly after a freeway branches, or in an adjacent lane just before merging.
● Stickers are attached to the rear of the preceding vehicle.
● A sign resembling a system compatible sign is recognized.
● Side road speed signs may be detected and displayed (if positio ned in sight
of the front camera) while the vehicle is traveling on the main road.
● Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front camera) while traveling on a round about.
● The front of the vehicle is raised or lowered due to the carrie d load.
● The surrounding brightness is not sufficient or changes suddenly.
● When a sign intended for trucks, etc. is recognized.
● The navigation system map data is outdated.
● The navigation system is not operating.
● The speed information displayed on the meter and on the navigation system
may be different due to the navigation system using map data.
■ Speed limit sign display
If the engine switch was last turned off while a speed limit si gn was displayed
on the multi-information display, the same sign displays again when the
engine switch is turned to ON.
■ If “RSA Malfunction Visit Your Dealer” is shown
The system may be malfunctioning. Have the vehicle inspected by your Toy-
ota dealer.
■ Customization
Some functions can be customized. ( P. 100)

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing 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 s peed 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 su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal (start-off o peration) will
resume follow-up cruising. If the start-off operation is not pe rformed, sys-
tem control continues to keep your vehicle stopped.
