Battery-saving function
In the following circumstances, the entry function is disabled in order to
prevent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for 30 days or more
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when...
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion.
(P. 52)
The vehicle is locked/unlocked using the mechanical key. (P. 458)
Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is
about a year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
engine stops. (P. 440)
The battery becomes depleted even if the electronic key is not used
because the key always receives radio waves. If the smart entry & start
system or the wireless remote control does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary.
(P. 388)
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic
field.

Before driving
IS F_EE
CAUTION
Refueling the vehicle
Observe the following precautions while refueling the vehicle.
Failure to do so may result in death or serious injury.
Touch the vehicle or some other metal surface to discharge any static elec-
tricity.
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
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
bodies 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 igni-
tion hazard.
When 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 serious injury.

nect the ground cable.
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.

tialize the system.
