2-1. Driving procedures
When stopping the hybrid system with the shift lever in a position other
than P
If the hybrid system is stopped with the shift lever in a position
other than P, the "POWER" switch will not be turned off but
instead be turned to ACCESSORY mode. Perform the following
procedure to turn the switch off:
STEP 1
Check that the parking brake is set.
STEP 2
Shift the shift lever to P.
STEP 3
Check that the indicator on the "POWER" switch is illumi-
nated in amber and then press the "POWER" switch once.
STEP 4
Check that the indicator on the "POWER" switch is off.

Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON
mode with the hybrid system not operating for more than 20 minutes
(ACCESSORY mode) or one hour (ON mode), 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 sys-
tem 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 engine may not start or the "POWER"
switch mode may not change. It is not necessary to press and hold the
switch.
