Automatic cancelation of c onstant 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  an y  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  b e  heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic 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 detect ing the vehicle ahead
In  the  case  of  the  following  and  depending  on  the  conditions,  o perate  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 o f 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
● Vehicles with small rear ends (trailers with no load on board,  etc.)
● Motorcycles traveling in the same lane

Intuitive parking assist
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel  parking  or  maneuvering  into  a  garage  is  measured  by  the
sensors  and  communicated  via  t he  multi-information  display
and  a  buzzer.  Always  check  the  surrounding  area  when  using
this system.

■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 syst em).
• 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 syst em).
• The shift lever is in R.
■ Intuitive parking assist display
When  an  obstacle  is  detected  while  the  Toyota  parking  assist  mo nitor  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  th e  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  ma y  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 gr ass.
• The  vicinity  of  the  vehicle  is  noisy  due  to  vehicle  horns,  motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing 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 i nstalled.
• People may not be detected if they are wearing certain types o f 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  senso r  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 sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s  detection  areas  before  the  display  is  shown  and  the  wa rning
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  case s, if it is
removed  from  the  sensor,  the  system  should  return  to  normal. Al so,  due  to
the  sensor  being  frozen  at  low  temperatures,  a  malfunction  disp lay  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  d riven  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  t he  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 a rea.
Doing so may result in the sensor malfunctioning.
