●Close all the doors and windows, and turn the power switch off.
●Confirm the type of fuel.
■Fuel types
Premium unleaded gasoline (Octane rating 91 [Research Octane Number 96] or
higher)
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.

2504-4. Refueling
LS600hL_U(OM50E41U)
CAUTION
■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, pressur-
ized fuel may spray out 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
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 syst em 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.
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.
●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 the trunk.
Closing the fuel tank cap
CAUTION
■When replacing the fuel tank cap
Do not use anything but a genuine Lexus fu el tank cap designed for your vehicle.
Doing so may cause a fire or other incide nt which may result in death or serious
injury.
