The  vehicle-to-vehicle  distance  is
set  automatically  to  long  mode
when the engine switch is turned to
the “ON” position (vehicles without
a  smart  key  system)  or  IGNITION
ON  mode  (vehicles  with  a  smart
key system).
If a vehicle is running ahead of you, the preceding vehicle mark will also be
displayed.

Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.

Pulling  the  lever  toward  you
cancels the speed control.

The speed setting is also canceled
when 

the 

brake 

pedal 

is

depressed.

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

However,  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.

Warnings may not occur when

In the following instances, warnings may not occur even when the
vehicle-to-vehicle distance is small.

When  the  speed  of  the  preceding  vehicle  matches  or  exceeds
your vehicle speed

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 vehicle speed at the moment the lever is released becomes the set
speed.

Dynamic radar cruise control can be set when

The shift lever is in D or range 3 or higher of S has been selected.

Vehicle speed is at or above 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.

Automatic cancelation of vehicle-to-vehicle distance control mode

Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations:

Actual vehicle speed falls at or below approximately 25 mph (40 km/h).

VSC is activated.

TRAC is activated for a period of time.

When the VSC or TRAC system is turned off.

The sensor cannot detect correctly because it is covered in some way.

Pre-collision braking is activated.

If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

Automatic cancelation of constant speed control mode

Constant speed control mode is automatically canceled in the following situa-
tions:

Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.

Actual vehicle speed falls below approximately 25 mph (40 km/h).

VSC is activated.

TRAC is activated for a period of time.

When the VSC or TRAC system is turned off.

Pre-collision braking is activated.

If constant speed control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.

Brake system operation sound

If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle  distance  control  mode,  a  brake  system  operation  sound  may  be  heard.
This does not indicate a malfunction.

Warning messages and buzzers for dynamic radar cruise control 

Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.

When the sensor may not be correctly detecting the vehicle ahead

In  the  case  of  the  following  and  depending  on  the  conditions,  operate  the
brake  pedal  when  deceleration  of  the  system  is  insufficient  or  operate  the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (

P. 281) may not be activated.

Vehicles that cut in suddenly

Vehicles traveling at low speeds

Vehicles that are not moving in the same lane

Buzzer operation and distance to an obstacle

A buzzer sounds when the sensors are operating.

The buzzer sounds faster as the vehicle approaches an obstacle. 
When  the  vehicle  comes  within  the  following  distance  of  the
obstacle, the buzzer  sounds continuously: Approximately 1.2 ft.
(35 cm).

When  2  or  more  obstacles  are  detected  simultaneously,  the
buzzer system responds to the nearest obstacle. If one or both
come  within  the  above  distances,  the  beep  will  repeat  a  long
tone, followed by fast beeps.

Approximately 2.0 ft. (60 cm)
Approximately 4.9 ft. (150 cm)

The  diagram  shows  the  detection
range of the sensors. Note that the
sensors  cannot  detect  obstacles
that  are  extremely  close  to  the
vehicle.
The  range  of  the  sensors  may
change depending on the shape of
the object etc.

Intuitive parking assist can be operated when

Front corner sensors:
• The engine switch is in the “ON” position (without a smart key system) or

the engine switch is in IGNITION ON mode (with a smart key system).

• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).

Rear corner and rear center sensors:
• The engine switch is in the “ON” position (without a smart key system) or

the engine switch is in IGNITION ON mode (with a smart key system).

• The shift lever is in R.

Intuitive parking assist display

When  an  obstacle  is  detected  while  the Toyota  parking  assist  monitor  is  in
use, the warning indicator will appear in the upper part of the screen even if
the display setting has been set to off.

Sensor detection information

The sensor’s detection areas are limited to the areas around the vehicle’s
front corner and rear bumpers.

Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. 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 eyelet is installed.
• The bumper or sensor receives a strong impact.
• 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  the  sensor  to  be
closer than they are.

The  shape  of  the  obstacle  may  prevent  the  sensor  from  detecting  it.  Pay
particular 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  warning
beep sounds.

• Thin posts or objects lower than the sensor may not be detected for colli-

sion 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 air conditioning system.

When the system malfunctions

If “Clean park sonar” is shown
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  display  may
appear or an obstacle may not be detected. If the sensor thaws out, the sys-
tem should return to normal.

If “Check park sonar system” is shown
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-sensor

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 beep 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 a beep.

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.

Notes when washing the vehicle

Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
