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.

●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.

■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.
NOTICE

that the fuel filler door lock is not pushed
by the fuel nozzle boot, etc., as this may
cause a valve to close, possibly resulting
in a fuel spill.
If the fuel filler door lock has been
pushed, operate the fuel filler door
opener switch in the vehicle before con-
tinuing to refuel.

WARNING
■Toyota Safety Sense 2.0
The Toyota Safety Sense 2.0 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.
