Sensor detection information

●

The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.

●

Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve

this problem.)

• The sensor is frozen. (Thawing the area will resolve this problem.) 

In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.

• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The  vicinity  of  the  vehicle  is  noisy  due  to  vehicle  horns,  motorcycle

engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.

• There  is  another  vehicle  equipped  with  parking  assist  sensors  in  the

vicinity.

• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

●

The shape of the obstacle may prevent a sensor from detecting it. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of

your vehicle

●

The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection

distance may shorten, or detection may be impossible.

• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even

at slow speeds, there is a possibility that the obstacle will come within the
sensor’s  detection  areas  before  the  display  is  shown  and  the  buzzer
sounds.

• Thin posts or objects lower than the sensor may not be detected when

approached, even if they have been detected once.

• It might be difficult to hear beeps due to the volume of audio system or air

flow noise of the air conditioning system.

■

Muting the buzzer sound

●

To mute the buzzer sound

The  buzzer  can  be  temporarily  muted  by  pressing 

  of  the  meter  control

switches while an obstacle detection display is shown on the multi-informa-
tion display.

●

To cancel the mute

Mute will be automatically canceled in the following situations.

• When the shift position is changed
• When the vehicle speed has reached or exceeded approximately 6 mph

(10 km/h)

• When the intuitive parking assist is turned off once and turned on again
• When the power switch is turned off once and turned to ON mode again
• When a sensor is malfunctioning

■

If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display

A  sensor  may  be  dirty  or  covered  with  snow  or  ice.  In  such  cases,  if  it  is
removed from the sensor, the system should return to normal. 
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.

■

If  “Parking  Assist  Malfunction  Visit  Your  Dealer”  is  displayed  on  the
multi-information display

Depending on the malfunction of the sensor, the device may not be working
normally. 
Have the vehicle inspected by your Toyota dealer.

WARNING

■

When using the intuitive parking assist

Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.

●

Do not use the sensor at speeds in excess of 6 mph (10 km/h).

●

The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the  sides  of  the  vehicle)  for  safety,  and  drive  slowly,  using  the  brake  to
control the vehicle’s speed.

●

Do not install accessories within the sensors’ detection areas.

NOTICE

■

When using intuitive parking assist

In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.

●

The intuitive parking assist operation display flashes, and a buzzer sounds
when no obstacles are detected.

●

If  the  area  around  a  sensor  collides  with  something,  or  is  subjected  to
strong impact.

●

If the bumper collides with something.

●

If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.

●

If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.

■

■

Sensor detection range

The detection range of the Parking Support Brake function (for static objects)
differs from the detection range of the intuitive parking assist (



P. 269).

Therefore, even if the intuitive parking assist detects and provides a warning
for  an  approaching  obstacle,  the  Parking  Support  Brake  function  (for  static
objects) may not start operating.

■

System operation

When the vehicle is stopped by system operation, the Parking Support Brake
function  (for  static  objects)  stops  and  the  PKSB  OFF  indicator  illuminates.
Even if operated, the brake control is released after 2 seconds, so the vehicle
can start moving in that state. Also, depressing the brake pedal releases the
brake control, so if the accelerator pedal is depressed again, the vehicle can
start moving.

■

System recovery

When the Parking Support Brake function (for static objects) is stopped by the
system operation and you would like to resume operation, turn the Parking
Support  Brake  function  (for  static  objects)  ON  again  and  resume  operation
(



P. 276), or after briefly turning the power switch OFF turn it ON again.

Furthermore, when the vehicle moves with an obstacle no longer in the trav-
eling  direction  of  the  vehicle,  or  when  the  traveling  direction  of  the  vehicle
changes (such as when switching from moving forward to reverse, and vice
versa), the system operation automatically resumes.

■

Obstacles not detected by the sensors

The following obstacles may not be detected by the sensors.

●

Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)

●

Objects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects

●

Low objects

●

Thin objects such as wires, fences, ropes and signposts

●

Objects that are extremely close to the bumper

●

Non-static obstacles

■

Intuitive parking assist buzzer

Regardless of whether the intuitive parking assist is on or off (



P. 266), if the

Parking Support Brake function (for static objects) is not stopped (



P. 276),

when the front or rear sensors detect an obstacle and brake control is per-
formed,  the  intuitive  parking  assist  buzzer  sounds  and  a  notification  of  the
approximate distance to the object is provided.

Situations when the system may operate even though there is no possi-
bility of a collision

In the following situations, the system may operate even though there is no
possibility of a collision.

●

Environmental influence

• The vehicle is driven toward a banner or flag, a low-hanging branch or a

boom  barrier  (such  as  those  used  at  railroad  crossings,  toll  gates  and
parking lots).

• There  is  an  obstacle  on  the  shoulder  of  the  road  (when  the  vehicle  is

driven in a narrow tunnel, on a narrow bridge or on a narrow road)

• The vehicle is being parallel parked
• There is a rut or hole in the surface of the road
• When the vehicle is driven on a metal cover (grating), such as those used

for drainage ditches

• The vehicle is driven on a steep slope
• The sensor is covered by water on a flooded road

●

Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system

returns to normal)

• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm

●

Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parking assist

system of another vehicle, a vehicle detector, a motorcycle engine or the
air brake of a large vehicle

• Electronic  components  (such  as  a  backlit  license  plate  (especially  fluo-

rescent  types),  fog  lights,  a  fender  pole  or  a  wireless  antenna)  are
installed near the sensors

• The  vehicle  is  driven  on  a  narrow

road

• The vehicle is driven on a gravel road

or in an area with tall grass

●

Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load

(the nose tilts up or down)

• The direction of the sensor has deviated due to a collision or other impact

■

In the unlikely event that the Parking Support Brake function (for static
objects) mistakenly operates at a crossing or elsewhere

Even in the unlikely event that the Parking Support Brake function (for static
objects) mistakenly operates at a crossing or elsewhere, brake control is can-
celed  after  approximately  2  seconds,  allowing  you  to  proceed  forward  and
leave the area. Furthermore, brake control is also canceled when the brake
pedal  is  depressed.  Depressing  the  accelerator  pedal  again  allows  you  to
proceed forward and leave the area.

■

Situations in which the system may not operate normally

In the following situations, the system may not operate normally.

●

Environmental influence
• There  is  an  obstacle  that  cannot  be  detected  between  the  vehicle  and

another obstacle that can be detected

• An obstacle such as another vehicle, a motorcycle, a bicycle or a pedes-

trian cuts in front of the vehicle or jumps out from the side.

●

Influence from the weather

• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system

returns to normal)

• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm

• The  area  around  the  sensor  is

extremely hot or cold

• The wind is strong

• The direction of the sensor has deviated due to a collision or other impact

■

When removing and installing the 12-volt battery

The system needs to be initialized.
The system can be initialized by driving the vehicle straight ahead for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or higher.

■

When “PKSB Unavailable” is displayed on the multi-information display
and the PKSB OFF indicator flashes

●

Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal. 
Also, a warning message may be displayed at low temperatures due to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.

●

If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle inspected at
your Toyota dealer.

●

System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.

WARNING

■

For safe use

Do  not  rely  solely  upon  the  system.  Relying  solely  upon  the  system  may
lead to an unexpected accident.

●

Driving safely is the sole responsibility of the driver. Pay careful attention
to the surrounding conditions in order to ensure safe driving. The Parking
Support Brake function (for static objects) can provide support to lessen
the severity of collisions. However, it may not operate depending on the
situation.

●

The  Parking  Support  Brake  function  (for  static  objects)  is  not  a  system
designed  to  completely  stop  the  vehicle.  Furthermore,  even  if  the  brake
control is able to stop the vehicle, brake control is canceled after approxi-
mately 2 seconds, so depress the brake pedal immediately.

■

In order for the system to operate properly

Make  sure  to  observe  the  following  precautions  regarding  the  sensors
(



P. 265). Failure to observe these precautions may cause the sensors

not to operate properly, and may result in an unexpected accident. 

●

Do not perform work such as modification, disassembly or painting

●

Only perform replacements using genuine parts

●

Do not subject the area around the sensors to any impacts

●

Do not damage the sensors, and always keep them clean

■

Handling the suspension

Do  not  modify  the  suspension,  as  changes  to  the  height  or  incline  of  the
vehicle  may  prevent  the  sensors  from  correctly  detecting  obstacles,  may
cause the system not operate, or may cause the system to operate unnec-
essarily.

The Blind Spot Monitor is a system that has 2 functions;

●

The Blind Spot Monitor function
Assists the driver in making the decision when changing lanes

●

The Rear Cross Traffic Alert function
Assists the driver when backing up

These functions use same sensors.

Summary of the Blind Spot Monitor

BSM outside rear view mirror indicators

Blind Spot Monitor function:
When a vehicle is detected in the blind spot, the BSM outside rear view
mirror indicator on the detected side illuminates. If the turn signal lever is
operated when a vehicle is in the blind spot, the BSM outside rear view
mirror indicator flashes.
Rear Cross Traffic Alert function:
When  a  vehicle  approaching  from  the  right  or  left  rear  of  the  vehicle  is
detected, the BSM outside rear view mirror indicators flash.

Rear  Cross Traffic Alert  buzzer  (Rear  Cross Traffic Alert  function
only)

When  a  vehicle  approaching  from  the  right  or  left  rear  of  the  vehicle  is
detected, a buzzer sounds from behind the rear seat.

●

Have a service technician inspect the condition of the 12-volt bat-
tery.

●

Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.

Ensure  that  all tires are the specified  size and brand, and that chains
match the size of the tires.

Perform the following according to the driving conditions: 

●

Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing. 

●

To  ensure  proper  operation  of  the  climate  control  system  fan,
remove  any  snow  that  has  accumulated  on  the  air  inlet  vents  in
front of the windshield. 

●

Check for and remove any excess ice or snow that may have accu-
mulated  on  the  exterior  lights,  vehicle’s  roof,  chassis,  around  the
tires or on the brakes.

●

Remove  any  snow  or  mud  from  the  bottom  of  your  shoes  before
getting in the vehicle.

Carry  out  the  necessary  preparations  and  inspections  before

Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions. 

Park  the  vehicle  and  shift  the  shift  position  to  P  without  setting  the
parking  brake. The  parking  brake  may  freeze  up,  preventing  it  from
being  released.  If  the  vehicle  is  parked  without  setting  the  parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehicle
to move unexpectedly, possibly leading to an accident.

Use the correct tire chain size when mounting the tire chains. 
Chain size is regulated for each tire size.
Side chain:

0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length

Cross chain:

0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length

Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.

■

Driving with tire chains

Observe the following precautions to reduce the risk of accidents. 
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.

●

Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.

●

Avoid driving on bumpy road surfaces or over potholes.

●

Avoid  sudden  acceleration,  abrupt  steering,  sudden  braking  and  shifting
operations that cause sudden regenerative braking.

●

Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

●

Do not use LDA (Lane Departure Alert with steering control) system.

NOTICE

■

Repairing or replacing snow tires

Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.

■

Fitting tire chains

The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Fogging up of the windows

●

The  windows  will  easily  fog  up  when  the  humidity  in  the  vehicle  is  high.
Turning 

 on will dehumidify the air from the outlets and defog the wind-

shield effectively.

●

If you turn 

 off, the windows may fog up more easily.

●

The windows may fog up if the recirculated air mode is used.

■

Windshield fog detection function

When automatic mode is set, the humidity sensor (



P. 314) detects fog on

the windshield and controls the air conditioning system to prevent fog.

■

Outside/recirculated air mode

●

When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation,  setting  the  recirculated  air  mode  will  also  cool  the  vehicle  interior
effectively.

●

Outside/recirculated  air  mode  may  automatically  switch  depending  on  the
temperature setting or the inside temperature. 

■

Operation of the air conditioning system in ECO HEAT/COOL mode

●

In ECO HEAT/COOL mode, the air conditioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Fluid  (heating)  heater  and  compressor  operation  controlled  to  restrict

heating/cooling capacity

• Fan speed restricted when automatic mode is selected

●

To improve air conditioning performance, perform the following operations:
• Adjust the temperature settings and fan speed
• Touch 

 while in 

, and 

 is set

• Touch 

 while in 

, and ECO HEAT/COOL mode is canceled

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning system to the outside air mode.

●

During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.

●

To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air

mode prior to turning the vehicle off.

• The start timing of the blower may be delayed for a short period of time

immediately  after  the  air  conditioning  system  is  started  in  automatic
mode.
