Conditions to turn the high beams on/off automatically

When all of the following conditions are met, the high beams will be turned
on automatically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.

If any of the following conditions is met, the high beams will turn off automat-
ically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.

Camera sensor detection information

The high beams may not be automatically turned off in the following situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road

dividers or roadside trees

• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on

The high beams may be turned off if a vehicle ahead that is using fog lights
without its headlights turned on is detected.

House lights, street lights, traffic signals, and illuminated billboards or signs
and other reflective objects may cause the high beams to change to the low
beams, or the low beams to remain on.

The  following  factors  may  affect  the  amount  of  time  taken  for  the  high
beams to turn on or off:
• The  brightness  of  the  headlights,  fog  lights,  and  tail  lights  of  vehicles

ahead

• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface,

etc.)

• The number of passengers and amount of luggage in the vehicle

The high beams may turn on or off unexpectedly.

Bicycles or similar vehicles may not be detected.

In the following situations the system may not be able to correctly detect the
surrounding brightness level. This may cause the low beams to remain on
or the high beams to flash or dazzle pedestrians or vehicles ahead. In such
a case, it is necessary to manually switch between the high and low beams.

4-4. Refueling

4RUNNER (U)

WARNING

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.

After  exiting  the  vehicle  and  before  opening  the  fuel  door,  touch  an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A  whooshing  sound  may  be  heard  when  the  fuel  tank  cap  is  loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.

Do  not  allow  anyone  that  has  not  discharged  static  electricity  from  their
body to come close to an open fuel tank.

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

Securely insert the fuel nozzle into the fuel filler neck.

Stop filling the tank after the fuel nozzle automatically clicks off.

Do not top off the fuel tank.

NOTICE

Refueling

Do not spill fuel during refueling. 
Doing  so  may  damage  the  vehicle,  such  as  causing  the  emission  control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

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 distance and relative speed between your

vehicle and the vehicle ahead or other objects)

• Images from the camera sensor (available only when the pre-colli-

sion braking function or the pre-collision brake assist function was
operating)

The  pre-collision  system  does  not  record  conversations,  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 except:

• With the consent of the vehicle owner or with the consent of the

lessee if the vehicle is leased
