When starting the hybrid system
Always start the hybrid system while sittin g in the driver’s seat. Do not depress the
accelerator pedal while starting the hy brid system under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.■
Caution while driving
If hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and comp lete stop. The steering lock function will
activate and this may lead to an accident, resulting in death or serious injury. ■
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle, press
and hold the power switch for more than 2 se conds, or press it briefly 3 times or more
in succession. (  P. 5 5 7 )
However, do not touch the power switch whil e driving except in an emergency. Turning
the hybrid system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more difficult to steer
smoothly, so you should pull over and stop the vehicle as soon as it is safe to do so.
NOTICE ■
To prevent 12-volt battery discharge ●
Do not leave the power switch in ACCESSORY or ON mode for long periods of
time without the hybrid system on. ●
If “ACCESSORY” or “IGNITION ON” is disp layed on the multi-information display
while the hybrid system is not operating, the power switch is not off. Exit the vehicle
after turning the power switch off. ●
Do not stop the hybrid system when the shift lever is in a position other than P. If the
hybrid system is stopped in another shift lever position, the power switch will not be
turned off but instead be turned to ACCESSORY mode. If the vehicle is left in
ACCESSORY mode, 12-volt battery discharge may occur. ■
When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by your Lexus
dealer immediately. ■
Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating so mewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

Before refueling the vehicle WA R N I N G ■
When refueling the vehicle
Observe the following precautions while refu eling the vehicle. Failure to do so may
result in death or serious injury. ●
After exiting the vehicle and before openin g 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 fr om static electricity can cause fuel vapors
to ignite while refueling. ●
Always hold the grips on th e 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 th at 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.
