2-1. Driving procedures CAUTION n 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. n 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 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 n To prevent 12-volt battery discharge l Do not leave the "POWER" switch in ACCESSORY or ON mode for long peri- ods of time without the hybrid system on. l 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. l 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. n When starting the hybrid system Do not depress the accelerator pedal unnecessarily. n 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. 170
