Auto power off function

If the vehicle is left in ACCESSORY or ON mode (the hybrid system is not operating)
for more than an hour with the shift lever in P, the “POWER” switch will automatically
turn off. However, this function cannot entirely prevent 12-volt battery discharge. Do not leave the vehicle with the “POWER” switch in ACCESSORY or ON mode for long periods of time when the hybrid system is not operating.

Operation of the “POWER” switch

When operating the “POWER” switch, one short, firm press is enough. If the switch
is pressed improperly, the hybrid system may not start or the “POWER” switch mode may not change. It is not necessary to press and hold the switch.

It may take time until the “READY” indicator comes on.

If the hybrid system does not start

The immobilizer system may not have been deactivated.

Steering lock motor overheating prevention

To prevent the steering lock motor from overheating, the motor may be suspended
if the hybrid system is turned on and off repeatedly in a short period of time. In this
case, refrain from operating the hybrid system. After about 2 seconds, the steering
lock motor will resume functioning.

When the “POWER” switch indicator flashes in amber

The system may be malfunctioning. Have the vehicle inspected by your Lexus dealer immediately.

If the “READY” indicator does not come on

If the “READY” indicator does not come on when you press the “POWER” switch with the shift lever in P and the brake pedal depressed, contact your Lexus dealer
immediately.

CAUTION:
When starting the hybrid system Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.

Doing so may cause an accident resulting in death or serious injury.

Caution while driving
If a hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the steering
lock in this circumstance 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 3 seconds.

However, do not touch the “POWER” switch while driving unless in an emergency.

If the hybrid system stops while driving, this could lead to an accident.

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 the indicator on the “POWER” switch is illuminated, the “POWER” switch is not
off. When exiting the vehicle, always check that the “POWER” switch is 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 Do not depress the accelerator pedal unnecessarily.

Symptoms indicating a malfunction with the “POWER” switch If the “POWER” switch seems to be operating somewhat differently than usual, such as the switch sticking slightly, there may be a malfunction. Contact your Lexus
dealer immediately.
