You can adjust the autolamp to keep the lamps
on after you leave your vehicle. The further you
move the headlamp knob to the left
(counterclockwise), the longer the lamps stay on.
You can set the autolamp so the lamps stay on
for up to three minutes after you turn your
vehicle off.
Lighting Up the Interior and Instrument
Panel
With the parking lamps or headlamps
illuminated, you can brighten or dim the lights
in the instrument panel. To do this, locate the
switch above the headlight control knob and
press it up (to brighten the lights) or down (to
dim the lights). To turn the interior lights on
and off, push the headlamp knob in.
The knob controls the light on the instrument panel and
the interior light (autolamp feature shown — other models
similar)
