2-1. Driving procedures
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 peri-
●
ods 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.
