2344-3. Operating the lights and wipers
AFS  (Adaptive  Front-lighting  System)  secures  excellent  visibility  at
intersections and on curves by automatically adjusting the dire ction of
the  light  axis  of  the  headlights  according  to  vehicle  speed  and  the
degree of the tire’s  angle as controlled  by steering input.
AFS operates at speeds of 6 mph (10 km/h) or higher.
■Daytime running light system
●Type A: 
The daytime running lights illuminate using the same lights as the headlights
and illuminate darker than the headlights. 
Type B: 
The  daytime  running  lights  illuminate  using  the  same  lights  as  the  parking
lights and illuminate brighter than the parking lights.
● To  make  your  vehicle  more  visible  to  other  drivers  during  dayti me  driving,
the  daytime  running  lights  turn  on  automatically  when  all  of  th e  following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the   (Canada only),   or 
* posi-
tion
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● For U.S.A.: Daytime running lights can be turned off by operati ng the switch.
● Compared  to  turning  on  the  headlights,  the  daytime  running  ligh t  system
offers greater durability and consumes less electricity, so it  can help improve
fuel economy.
■ Headlight control sensor
AFS (Adaptive Front-light ing System) (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything
that  blocks  the  sensor  is  affixed  to  the
windshield. 
Doing  so  interferes  with  the  sensor
detecting  the  level  of  ambient  light  and
may  cause  the  automatic  headlight  sys-
tem to malfunction.

Driving
The  pre-collision  system  is  equipped  with  a  sophisticated  computer
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 dist ance and relative speed between y our
vehicle and the vehicle  ahead or other objects)
• Images  from the camera  sensor (available  only  when  the  pre-col li-
sion  braking  function  or  the  pre-collision  brake  assist  functio n  was
operating)
The  pre-collision  system  does  not  record  con versations,  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 exc ept:
• With the consent of the vehicle owner or with the consent of t he
lessee if the vehicle is leased
• In response to an official request by the police, a court of l aw 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
● Recorded images can be erased  using a specialized device.
The image recording function can be disabled. However, if the f unc-
tion  is  disabled,  data  from  when  the  pre-collision  system  opera tes
will not be available.

Driving◆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.
◆Pre-collision brake assist
When  the  system  determines  that  the  possibility  of  a  frontal  colli-
sion  is  high,  the  system  applies  greater  braking  force  in  relat ion  to
how strongly the brak e pedal is depressed.
◆Pre-collision braking
When  the  system  determines  that   the  possibility  of  a  frontal  colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal  collision is extremely high, the brakes
are  automatically  applied  to  hel p  avoid  the  collision  or  reduce the
collision speed.
PCS (Pre-Collision System)
The  pre-collision  system  uses  a  radar  sensor  and  camera  sen-
sor  to  detect  vehicles  and  pedest rians  in  front  of  your  vehicle.
When the system determines that t he possibility of a frontal col-
lision with a vehicle or pedest rian 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 possi bility 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  th e
impact of the collision.
The  pre-collision  system  can  b e  disabled/enabled  and  the  warnin g
timing can be changed. ( P.   2 5 8 )

Driving
• When  a  very  bright  light,  such  as  the  sun  or  the  headlights  of  oncomingtraffic, shines directly into the camera sensor
• When  the  surrounding  area  is  dim,  such  as  at  dawn  or  dusk,  or  while  at
night or in a tunnel
• After the hybrid system has started the vehicle has not been d riven for a
certain amount of time
• While  making  a  left/right  turn  and  for  a  few  seconds  after  mak ing  a  left/
right turn
• While driving on a curve and for a few seconds after driving o n a curve
• If your vehicle is skidding
• If the wheels are misaligned
• If a wiper blade is blocking the camera sensor
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill 
• If the radar sensor or camera sensor is misaligned
● In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If  the  braking  functions  cannot  operate  to  their  full  extent,  such  as  when
the brake parts are extremely cold, extremely hot, or wet
• If  the  vehicle  is  not  properly  maintained  (brakes  or  tires  are   excessively
worn, improper tire inflation pressure, etc.)
• When  the  vehicle  is  being  driven  on  a  gravel  road  or  other  sli ppery  sur-
face
• If  the  front  of  the  vehicle  is  raised  or
lowered

2804-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehi cles
up  to  approximately  328  ft.  (100  m)  ahead,  determines  the  curre nt
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  travel ing  on  long
downhill slopes.
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-ve hicle  dis-
tance switch.
Example of deceleration crui sing 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  s peed  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  su ffi-
ciently to prevent your vehicle from closing in on the vehicle  ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+  RES”  switch  or  depressing  the   accelerator  pedal  will  resume follow-up
cruising.

Driving
■Dynamic radar cruise control wi th full-speed range can be set when
● The shift lever is in D or range 4 or higher of S has been sele cted. 
● Range 4 or higher of D has been selected by using the paddle sh ift switch. 
(vehicles with paddle shift switches)
● Vehicle  speed  is  at  or  above  approximately  30  mph  (50  km/h).  Ho wever,
when a preceding vehicle is detected, the dynamic radar cruise control with
full-speed range can be set even if the vehicle speed is at or  below approxi-
mately 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-vehicl e  distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ When the vehicle stops while follow-up cruising
●Pressing  the  “+  RES”  switch  while  the  vehicle  ahead  stops  will  resume  fol-
low-up  cruising  if  the  vehicle  ahead  starts  off  within  approxim ately  3  sec-
onds after the switch is pressed.
● 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 mo de
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations:
● Actual vehicle speed falls at or below approximately 25 mph (40  km/h) when
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).  Other wise,  the
sensor  cannot  properly  detect  the  vehicle.  (“Radar  Cruise  Contr ol  Unavail-
able” is displayed on the multi-information display)
● 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.
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● The  following  are  detected  when  the  vehicle  has  been  stopped  by   system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
If  vehicle-to-vehicle  distance  control  mode  is  automatically  ca nceled  for  any
other reason, there may be a malfunction in the system. Contact  your Toyota
dealer.

2884-5. Using the driving support systems
■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  with
full-speed range
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. 285) 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

Driving
●When  water  or  snow  thrown  up  by  the  surrounding  vehicles  hinders  the
detecting of the sensor
■ Conditions  under  which  the  vehic le-to-vehicle  distance  control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a  tunnel or on
a bridge
● While  the  vehicle  speed  is  decreasing  to  the  set  speed  after  th e  vehicle
accelerates by depressing the accelerator pedal
●
When  your  vehicle  is  pointing  upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding  vehicle  has  an  extremely
high ground clearance
●When  the  road  curves  or  when  the
lanes are narrow
● When  steering  wheel  operation  or  your
position in the lane is unstable

2904-5. Using the driving support systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force co rre-
sponding to the brake operation
◆ABS (Anti-lock  Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while  driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps  the  driver  to  control  skidding  when  swerving  suddenly  or
turning on slippery road surfaces.
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control  of the ABS, TRAC, VSC and EPS.
Helps  to  maintain  directional  stability  when  swerving  on  slippe ry
road surfaces by controlling steering performance.
◆Secondary Collision Brake
When  the  airbag  sensor   detects  a  collision,  the  brakes  and  stop
lights are  automatically control led  to reduce  the  vehicle  speed  and
that helps reduce the possibilit y of further damage due to a se cond-
ary collision
◆TRAC (Traction Control)
Helps  to  maintain  drive  power  and  prevent  the  drive  wheels  from
spinning when starting the vehicl e or accelerating on slippery roads
Driving assist systems
To  keep  driving  safety  and  perf ormance,  the  following  systems
operate  automatically  in  respon se  to  various  driving  situations.
Be  aware,  however,  that  these  systems  are  supplementary  and
should  not  be  relied  upon  too  heav ily  when  operating  the  vehi-
cle.

2944-5. Using the driving support systems
■Automatic reactivation of TRAC and VSC systems
After  turning  the  TRAC  and  VSC  systems  off,  the  systems  will  be   automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If  only  the  TRAC  system  is  turned  off,  the  TRAC  will  turn  on  wh en  vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Secondary Collision Brake  operating conditions
The vehicle speed is approximately 6 mph (10 km/h) or more and  the airbag
sensor  detects  a  collision.  (The  Secondary  Collision  Brake  will   not  operate
when the vehicle speed is below approximately 6 mph [10km/h].)
■ Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ Reduced effectiveness of the EPS system
The  effectiveness  of  the  EPS  system  is  reduced  to  prevent  the  s ystem  from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain
from  excessive  steering  input  or  stop  the  vehicle  and  turn  the  hybrid  system
off. The EPS system should return to normal within 10 minutes.
