Turn Signals and Headlights
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.
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.

LIGHT SENSOR
The automatic lighting feature is
controlled by a sensor located on top
of the dashboard. Do not cover this
sensor or spill liquids on it.
Daytime Running Lights
With the headlight switch in the off
or position, the high beam
headlights and the high beam
indicator come on with reduced
brightness when you turn the
ignition switch to the ON (II)
position and release the parking
brake. They remain on until you turn
the ignition switch off, even if you
set the parking brake.
The headlights revert to normal
operation when you turn them on
with the switch.
