AUTO The automatic lighting
−
feature turns on the headlights, all
other exterior lights, and the
instrument panel lights when it
senses low ambient light.
To turn on automatic lighting, turn
the light switch to AUTO. The lights
will come on automatically when the
outside light level becomes low (at
dusk, for example). The lights on
indicator comes on as a reminder.
The lights and indicator will turn off
automatically when the system
senses high ambient light.
The lights will remain on when you
turn off the ignition switch. They will
turn off automatically when you open
and close the driver's door. To turn
them on again, either turn the
ignition switch to the ON (II)
position or turn the light switch to
the position.
Even with the automatic lighting
feature turned on, we recommend
that you turn on the lights manually
when driving at night or in a dense
fog, or when you enter dark areas
such as long tunnels or parking
facilities.
To change the ''AUTO LIGHT
SENSITIVITY'' setting, see page
120 .
Do not leave the light switch in
AUTO if you will not be driving the
vehicle for an extended period (a
week or more). You should also turn
off the lights if you plan to leave the
engine idling or off for a long time.
