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.

WARNING

Caution regarding the use of washer fluid

When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.

NOTICE

When the windshield is dry

Do not use the wipers, as they may damage the windshield.

When the washer fluid tank is empty

Do not operate the switch continually as the washer fluid pump may over-
heat.

4-4. Refueling

Turn the engine switch to the “LOCK” position and ensure that all
the doors and windows are closed.

Confirm the type of fuel.

Fuel types

P. 532

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.

If the malfunction indicator lamp illuminates

The malfunction indicator lamp may illuminate erroneously if refueling is per-
formed repeatedly when the fuel tank is nearly full.

Opening the fuel tank cap

Perform the following steps to open the fuel tank cap:

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.

the cap is released, it will turn
slightly in the opposite direction.

WARNING

When replacing the fuel tank cap

Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

Toyota Safety Sense P

The Toyota Safety Sense P consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:

WARNING

Toyota Safety Sense P

The Toyota Safety Sense P is designed to operate under the assumption
that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle's surround-
ings and driving safely.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

4RUNNER (U)

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 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

• In response to an official request by the police, a court of law 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 func-
tion is disabled, data from when the pre-collision system operates
will not be available.
