gers, etc. do not become caught in the windshield wipers.

■

Caution regarding the use of washer fluid

When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.

NOTICE

■

When the windshield is dry

4-4. Refueling

WARNING

■

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.

●

After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

●

Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.

●

Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.

●

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

●

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

●

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

■

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

●

Securely insert the fuel nozzle into the fuel filler neck.

●

Stop filling the tank after the fuel nozzle automatically clicks off.

●

Do not top off the fuel tank.

■

When the fuel filler door cannot be opened by pressing the inside switch

Using the lever to open the fuel filler door may not allow for an adequate
reduction in fuel tank pressure before refueling. To prevent fuel from spilling
out, turn the cap slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and
slowly.

Open the back door and remove the
cover underneath the luggage compart-
ment light.

Pull the lever backward and check that
the fuel lid opens.

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)

• Images from the camera sensor (available only when the pre-colli-

sion braking function or the pre-collision brake assist function 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 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



◆

Pre-collision warning

When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.



: If equipped

The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians 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. (

WARNING

■

Limitations of the pre-collision system

●

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.

●

Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision:



P. 298

• Conditions under which the system may not operate properly:



P. 300

●

Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking function is operating, a large amount of
braking force will be applied.

●

If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.

●

The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.

●

In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.

●

If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

Operational conditions

The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:

●

Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 7 mph (10 km/h) or more.

●

Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 20 and
50 mph [30 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 20 mph (30 km/h) or more.

●

Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 7 mph (10 km/h) or more.

The system may not operate in the following situations:

●

If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time

●

The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (

WARNING

■

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.

WARNING

■

Before using dynamic radar cruise control with full-speed range

●

Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.

●

The dynamic radar cruise control with full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:



P. 328

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly:



P. 330

●

Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.

●

Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying solely on this
system or assuming the system ensures safety while driving can lead to
an accident, resulting in death or serious injury.

●

Switch the dynamic radar cruise control with full-speed range off using the
“ON-OFF” button when not in use.

WARNING

■

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.

●

Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.

●

Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead is within a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.

●

Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range does not include
functions which will prevent or avoid collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any possibility of danger, the driver must
take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.

WARNING

■

Situations unsuitable for dynamic radar cruise control with full-speed
range

Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.

●

Roads where there are pedestrians, cyclists, etc.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those covered with rain, ice or snow

●

On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.

●

At entrances to freeways and highways

●

When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

●

When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor

●

In traffic conditions that require frequent repeated acceleration and decel-
eration

●

During emergency towing

●

When an approach warning buzzer is heard often

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 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.

Driving in vehicle-to-vehicle distance control mode

PRIUS_OM_OM47D44U_(U)

4-5. Using the driving support systems

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.
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 will resume fol-
low-up cruising.

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.

After the vehicle ahead of you
starts off, push the lever up.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.

Pulling the lever toward you
cancels the speed control.

The speed control is also canceled
when

the

is

depressed.
(When the vehicle has been
stopped

by

control,

depressing the brake pedal does
not cancel the setting.)

Pushing the lever up resumes the cruise control and returns vehicle
speed to the set speed.

However, when a vehicle ahead is not detected, cruise control does not
resume when the vehicle speed is approximately 25 mph (40 km/h) or less.

When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.

When constant speed control mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.

With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.

Immediately after the “ON-OFF”
button is pressed, the radar cruise
control indicator will come on.
Afterwards, it switches to the cruise
control indicator.
Switching to constant speed con-
trol mode is only possible when
operating the lever with the cruise
control off.

Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 25 mph
[40 km/h]) and push the lever
down to set the speed.

Cruise control “SET” indicator will
come on.

●

The shift position is in D.

●

Vehicle speed is at or above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic radar cruise
control with full-speed range can be set even if the vehicle speed is below
approximately 30 mph (50 km/h).

■

Accelerating after setting the vehicle speed

The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.

■

●

Pushing the lever up while the vehicle ahead stops will resume follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.

●

If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.

■

Automatic cancelation of vehicle-to-vehicle distance control mode

there are no vehicles ahead.

●

The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed at or below approximately 25 mph (40 km/h). Otherwise, the
sensor can not properly detect the vehicle.

●

VSC is activated.

●

TRAC is activated for a period of time.

●
