■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation se veral times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
● If the wiper switch is turned to the position while the power switch is in
ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 85C (185F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed. (Customizable features:
 P. 670)
● The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

Driving
PRIUS_OM_OM47F32E_(EE)●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 any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
• 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 extremely
cold environment
• When the front camera cannot detect objects in front of the vehicle, 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, the radar may
judge the surrounding environment can not be properly recognized. In
that case, “Pre-Collision System Unavailable” is displayed.

Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on (P. 153)
of the multi-information display.
The system is automatically enabled each time the power switch is
turned to 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-collision warning timing
The pre-collision warning timing can be changed on (P. 153)
of the multi-information display.
The warning timing setting is retained when the power switch is turned
off.
However, if the pre-collision system is disabled and re-enabled, the
operation timing will return to the default setting (middle).

denly, such as at the entrance or exit of a tunnel

In the following situations, the RSA system will notify the driver.
●When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphasized
and a buzzer will sound.
●When the RSA system recognizes a no-entry sign and detects that
the vehicle has entered a no-entry area based on the map informa-
tion of the navigation system, the no-entry sign flashes and a
buzzer will sound.(For vehicles with navigation system)
●If it is detected that your vehicle is overtaking when a no overtaking
sign is displayed on the multi-information display, the displayed sign
will flash and a buzzer will sound.
Depending on the situation, traffic environment (traffic direction,
speed unit) may be detected incorrectly and a notification function
may not operate properly.
■Setting procedure
P. 153
■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
●No sign has been recognized for a certain distance.
●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 does 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 incorrectly.
●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.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
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.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal (start-off opera-
tion) will resume follow-up cruising. If the start-off operation is not per-
formed, system control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
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.

●Adjusting the set speed by the lever
To change the set speed, operate the lever until the desired set
speed is displayed.
Increases the speed
(Except when the vehicle has
been stopped by system control
in vehicle-to-vehicle distance
control mode)
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the lever up or down to change the speed,
and release when the desired speed is reached.
In the vehicle-to-vehicle distance control mode, the set speed will
be increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1 or 1 mph (1.6 km/h)*2 each time
the lever is operated
Large adjustment: Increases or decreases in 5 km/h (3.1 mph)
*1 or 5 mph
(8 km/h)
*2 increments for as long as the lever is held
In the constant speed control mode (P. 340), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1 or 1 mph (1.6 km/h)*2 each time
the lever is operated
Large adjustment: The speed will continue to change while the lever is
held.
*1: When the set speed is shown in “km/h”
*2: When the set speed is shown in “MPH”
●Increasing the set speed by the accelerator pedal
Accelerate with accelerator pedal operation to the desired vehi-
cle speed.
Push the lever down.
