ing wheel will be locked due to the steering lock function. Operating the power
switch again automatically cancels the steering lock.

Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, operation of 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
10 seconds, the steering lock motor will resume functioning.
When “Check Entry & Start System” is displayed on the multi-information dis-
play
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional 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 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 vehi-
cle, press and hold the power switch for more than 2 seconds, or press it briefly
3 times or more in succession. (P. 499)
However, do not touch the power switch while driving except in an emergency.
Turning the hybrid system off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, 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 displayed on the meters 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
Do not depress the accelerator pedal unnecessarily.
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately.
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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional immediately.
