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 12-volt battery dis-
charge. 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.
