After refueling more than approximately 1.3 gal. (5 L, 1.1 Imp.gal.) and turn-
ing the power switch to ON mode, the gasoline price setting screen will be
automatically displayed on the multi-information display. ( →P. 128)
The fuel tank of your vehicle has a special structure, which
requires a reduction in fuel tank pressure before refueling. After
the opener switch has been pressed, it will take several seconds

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 of 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.

4-4. Refueling
Press the opener to open the
fuel filler door.
The fuel filler door will open within
about 10 seconds of the switch
being pressed. Before refueling is
possible, a message will be shown
on the multi-information display in
the instrument cluster to indicate
the progress of the fuel filler door
opener.
Turn the fuel tank cap slowly to
open and hang it on the back of
the fuel filler door.
NOTICE
■Refueling
● Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may overflow during the refuel-
ing process.
Press the fuel filler door opener switch again.
● 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.

■When the fuel filler door cannot be opened by pressing the inside switch
Using the lever to open the fuel filler door may not allow for an adequate
reduction in fuel tank pressure before refueling. To prevent fuel from spilling
out, turn the cap slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and
slowly.Open the back door and remove the
cover underneath the luggage compart-
ment light.
Pull the lever backward and check that
the fuel lid opens.

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.

4-5. Using the driving support systems
The pre-collision system is equipp ed with a sophisticated computer
that will record cert ain data, such as:
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distanc e 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 recor ded 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.
