nBattery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
lWhen the entry function has not been used for a month or more
lWhen the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when
lThe vehicle is locked using the door handle lock switch.
lThe vehicle is locked/unlocked using the wireless remote control function.
(→P. 36 )
lThe vehicle is locked/unlocked using the mechanical key. (→P. 41 7 )
nElectronic key battery depletion
lThe standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
lThe battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary.
(→ P. 345)
lTo avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field.

1-5. Refueling
CAUTION
nRefueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so, may
result in death or serious injury.
lTouch the vehicle or some other metal surface to discharge any static electricity.
Sparks resulting from discharging static electricity may cause the fuel vapors to
ignite.
lAlways 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.
lDo not allow anyone that has not discharged static electricity from their bodies to
come close to an open fuel tank.
lDo not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
lDo not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
lDo 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.
nWhen replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Failure to do so may cause a fire or other incident which may result in death or seri-
ous injury.
NOTICE
nRefueling
Do not spill fuel during refueling.
Failing to do so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel system components or the vehicle's painted
surface.
