2684-4. Refueling
RX450h_U_OM0E013U
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 fr om 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.
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 refueling 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.

Press the switch to open the fuel
filler door.
The fuel filler door will open within about
10 seconds of the sw itch being pressed.
Before refueling is possible, a message
will be shown on the multi-information
display in the instrument cluster to indi-
cate the progress of the fuel filler door
opener.
Turn the fuel tank cap slowly and
remove it, then put it into the holder
on the fuel filler door.

●If the fuel filler door opener switch cannot be
operated, contact your Lexus dealer to service
the vehicle. In case where refueling is urgently
necessary, the fuel filler door can be opened
using the lever in th e luggage compartment.
●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 ai r being discharged from
inside the fuel tank. Therefore, fill the fuel tank
carefully and slowly.
