Headlight automatic-shutdown function
Even if the lighting switch (taillight switch or headlight switch) is
ON, the head light (including the taillights) will automatically go
off in the following conditions to prevent the battery from dis-
charging as a result of forgetting to turn off lights.
When the ignition key is turned from "ON" to "LOCK" (OFF) or
"ACC" position with the lighting switch turned ON, and this
state continues for three minutes, the light will automatically be
turned off. If the driver's door is opened during these three min-
utes, the light will go off one second later.
NOTE: This function can be disabled by the adjustment proce-
dures of SWS function (Refer to
Dimmer automatic reset function
The column switch (column ECU) resets the dimmer switch and
prevents the high beam from lighting up when turning on the
headlight again if the headlight switch is put in the "OFF" posi-
tion while the high beam of the headlight is on (including the
instance when the dimmer switch is erroneously put in the "ON"
state upon passing operations) and resets the dimmer switch.
