When stopping the engine with the shift lever in a position other than P
If the engine is stopped with the shift lever in a position other than P, the
“ENGINE START STOP” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to turn
the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “ENGINE START STOP” switch
is illuminated in amber and then press the “ENGINE START
STOP” switch once.
Check that the indicator on the “ENGINE START STOP” switch
is off.
■Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or IGNITION ON
mode with the engine not running for more than 20 minutes (ACCESSORY mode)
or one hour (IGNITION ON mode), the “ENGINE START STOP” switch will auto-
matically turn off. However, this function cannot entirely prevent battery discharge.
Do not leave the vehicle with the “ENGINE START STOP” switch in ACCESSORY
or IGNITION ON mode for long periods of time when the engine is not running.
■Operation of the “ENGINE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to press
and hold the switch.
