Lexus NX450H+ (2022 year). Manual in english

WARNING

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.

Precautions for refueling

Make sure to select a compatible type of fuel and refuel safely.

WARNING

Observe the following precautions while refueling the vehicle.

●

After exiting the vehicle and before opening the fuel door, touch an unpainted metal
surface to discharge any static electricity.
Also, do not allow anyone that has not discharged static electricity from their body to
come close to the fuel filler door.
Sparks resulting from static electricity discharge may cause fuel vapors to ignite while
refueling.

●

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.

●

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

●

When refueling your vehicle, make sure that the
fuel filler door lock is not pushed by the fuel nozzle
boot, etc., as this may cause a valve to close, possi-
bly 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 continuing to refuel.

●

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.

NOTICE

●

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 compo-
nents or the vehicle’s painted surface.

INFORMATION

■

Fuel tank opening for unleaded gasoline

To help prevent refueling with the incorrect fuel, your vehicle has a fuel tank opening
designed to only accommodate the special nozzle on unleaded fuel pumps.

Close the fuel tank cap

After refueling, turn the fuel tank cap until you
hear a click.

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

WARNING

If replacing the fuel tank cap, do not use anything but a genuine Lexus fuel tank cap
designed for your vehicle. Doing so may cause a fire.

INFORMATION

■

When "Check Fuel Cap" is displayed on the multi-information display

The fuel tank cap may be unfastened or loose. Turn the power switch off, check the cap
and tighten it securely. If the message remains, wait a few seconds and then turn the
power switch off once again.
