Lexus RX (RX 350L, RX450h) 2016-2024 Owners Manual: Refueling

Opening the fuel tank cap

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 until the vehicle is ready for refueling.

Before refueling the vehicle

• Close all the doors and windows, and turn the power switch off.
• Confirm the type of fuel.

■ 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.

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.

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.

Opening the fuel tank cap

1. Press the switch 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.

2. Open the fuel filler door until it is securely locked.

3. Turn the fuel tank cap slowly and remove it, then put it into the holder on the fuel filler door.

■ When the fuel filler door cannot be opened by pressing the inside switch

RX450h

• If the fuel filler door cannot be opened by pressing the rear edge of the fuel filler door with the doors unlocked, remove the cover inside the luggage compartment and pull the lever to open the fuel filler door.
• 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 discharged from inside the fuel tank. Therefore, fill the fuel tank carefully and slowly.

RX450hL

If the fuel filler door cannot be opened by pressing its rear edge with the doors unlocked, remove the cover inside the luggage compartment using a tool, such as a flathead screwdriver, and pull the lever to open the fuel filler door.

When using a screwdriver, make sure to wrap its tip with tape to protect the cover.

NOTICE

■ When refueling 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, 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 continuing to refuel.

Closing the fuel tank cap

1. 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.

2. Close the fuel filler door.

WARNING

■ When 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 or other incident which may result in death or serious injury.
