2-1. Driving procedures CAUTION n 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. 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. 2 When driving 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 hybrid system is off, but the indicator on the "POWER" switch is illuminated, this indicates that the "POWER" switch is still turned on. When exiting the vehicle, always check that the "POWER" switch is off. 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. 149
