*1: These lights turn on when the engine switch is turned to the “ON” position(vehicles without a smart key system)  or the engine switch is turned to the
IGNITION  ON  mode  (vehicles  with  a  smart  key  system)  to  indicate  that  a
system  check  is  being  performed.  They  will  turn  off  after  the  engine  is
started, or after a few seconds. There may be a malfunction in a system if
a  light  does  not  come  on,  or  if  the  lights  do  not  turn  off.  Have  the  vehicle
inspected by your Toyota dealer.

Automatic High Beam
Push the lever away from you with
the  headlight  switch  in  the 
position.
The  Automatic  High  Beam  indica-
tor  will  come  on  when  the  head-
lights  are  turned  on  automatically
to  indicate  that  the  system  is
active.
When  all  of  the  following  conditions are  fulfilled,  high  beam  will  be
automatically turned on (after approximately 1 second):
● Vehicle speed is above appr oximately 20 mph (32 km/h).
● The area ahead of the vehicle is dark.
● There are no oncoming or preceding vehicles with headlights or tail
lights turned on.
If  any  of  the  following  conditions  are  fulfilled,  high  beam  will  be  auto-
matically turned off:
● Vehicle speed drops below approximately 20 mph (32 km/h).
● The area ahead of the vehicle is not dark.
● Oncoming  or  preceding  vehicles  have  headlights  or  tail  lights
turned on.
: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetli ghts, the lights of oncoming and
preceding vehicles, etc., and au tomatically turns high beam on
or off as necessary.

Driving
■The Automatic High Beam can be operated when
The  engine  switch  is  in  the  “ON”  position  (vehicles  without  a  smart  key  sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
■ Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.
● High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
● Houselights,  streetlights,  red  traffic  signals,  and  illuminated  billboards  or
signs may cause the high beam to turn off.
● The following factors may affect the amount of time taken to turn high beam
on or off:
• The  brightness  of  headlights,  fog  lights,  and  tail  lights  of  oncoming  and
preceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
● High beam may be turned on or off when unexpected by the driver.

4-3. Operating the lights and wipers
●In  the  situations  below,  the  system  may  not  be  able  to  correctly  detect  the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you should consider turning the high beam on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles  ahead  have  headlights  that  are  either  switched  off,  dirty,  are changing color, or are not aimed properly.
• When  driving  through  an  area  of  in termittently  changing  brightness  and
darkness
• When  frequently  and  repeatedly  driving  ascending/descending  roads,  or roads  with  rough,  bumpy  or  uneven  surfaces  (such  as  stone-paved
roads, gravel tracks etc.)
• When  frequently  and  repeatedly  taking  curves  or  driving  on  a  winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
■ When the warning message is shown  on the multi-information display
P. 562
■ Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold   on the inside rear view mirror for
15 to 20 seconds, and release. The indicator light on the inside rear view mir-
ror will flash to indicate that the sensitivity has been lowered.
When  the  engine  switch  is  turned  to  the  “LOCK”  position  (vehicles  without  a
smart key system) or turned off (vehicles with a smart key system), the sensi-
tivity will be returned to its normal level.
■ Customization
The Automatic High Beam can be turned off.
