Unlock the doors using the wireless remote control and open one of the 
doors.
If a door is not opened  within 60 seconds after   is pressed, the doors 
will be locked again and the alarm will automatically be set.
In case that the alarm is triggered, immediately stop the alarm. ( P.  7 5 )
■Battery-saving function
In the following circumstances, the entry func tion is disabled in order to prevent the 
vehicle and electronic key batteries from discharging. 
●When the entry function has not been used for 2 months or more
●When 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... 
●The vehicle is locked using  the door handle lock switch
●The vehicle is locked/unlocked using the wireless remote control function  
(  P. 34) or the mechanical key ( P.  5 2 6 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The battery becomes depleted even if 
the electronic key is not used.) If the smart access system with push-button start 
or the wireless remote control function  does not operate, or the detection area 
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (  P. 440)
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of 
the following electrical appliances  that produce a magnetic field:
•TVs
• Personal computers
• Recharging cellular phones or cordless phones

1-5. Refueling
GS_G_U
May 13, 2008 5:14 pm
CAUTION
■When 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 electricity.
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 re moving the cap. In hot weather, pressur-
ized 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 an y person or object that is statically 
charged. 
This may cause static electricity to build up , resulting in a possible ignition hazard.
■When replacing the fuel tank 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
■Refueling
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 syst em components or the vehicle’s painted 
surface.

NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or 
when the fluid level in the accumulator is high. 
If the reservoir needs frequent refilli ng, it may indicate a serious problem.

GS_G_U
May 13, 2008 5:14 pm
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and 
explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect the 
ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.
■After recharging/reconnecting the battery
In some cases, the engine may not start. Follow one or both of the following proce-
dures:
●After opening and closing the driver’s door, wait 10 seconds then attempt to 
start the engine. (If the system does not start first time, repeat the procedure.)
●With the shift lever in “P” and the “ENGINE START STOP” switch is OFF, open 
and close any door, then attempt to start the engine.
If the system will not start even after mult iple attempts at both methods, contact 
your Lexus dealer.
