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

Do not use the wipers, as they may damage the windshield.

■

When the washer fluid tank is empty

Do not operate the switch continually as the washer fluid pump may over-

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.

The fuel filler door will open within
about  10  seconds  of  the  switch
being  pressed.  Before  refueling  is
possible, a message will be shown
on  the  multi-information  display  in
the  instrument  cluster  to  indicate
the  progress  of  the  fuel  filler  door
opener.

Turn the fuel tank cap slowly to
open and hang it on the back of

●

Finish  refueling  within  30  minutes.  If  more  than  30  minutes  passes,  the
internal valve closes. In this condition, fuel may overflow during the refuel-
ing process. 
Press the fuel filler door opener switch again.

●

Do not spill fuel during refueling. 
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

■

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.



: 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-

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

●

If the shift position is in R

●

If  VSC  is  disabled  (only  the  pre-collision  warning  function  will  be  opera-
tional)

■

Cancelation of the pre-collision braking

If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:

●

The accelerator pedal is depressed strongly.

●

The steering wheel is turned sharply or abruptly.

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

●

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

320

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.
