WARNING! Do not use daytime running lights
(DRL) during periods of darkness or reduced
visibility. Do not use DRL as a substitute for
headlights or other lights during operations
that require lighting of your vehicle. Doing so
could lead to an accident resulting in death or
personal injury.
NOTE:
On vehicles equipped with daytime running
lights (DRL), the high-beam headlamps go on auto-
matically at reduced brightness if the engine is run-
ning and the headlamp switch is turned off. The
daytime running lights are turned off automatically
while the parking brake is engaged. If the head-
lamp switch is turned on, the DRL system is over-
ridden & headlamps operate normally.
Panel Light Dimmer
The Panel Light Dimmer lets you vary the brightness of
your instrument panel lights.
To Operate Your Panel Light Dimmer:
1. Turn on either the headlights or clearance lights.
2. To brighten the instrument lights, rotate the thumb-
wheel up.
3. To dim the instrument lights, rotate the thumbwheel
down.
