CONTROLS AND DISPLAY
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 automatically
at reduced brightness if the engine is running
and the headlamp switch is turned off. The
daytime running lights are turned off automatically
while the parking brake is engaged. If the headlamp
switch is turned on, the DRL system is overridden
& headlamps operate normally.

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 thumbwheel
up.
3. To dim the instrument lights, rotate the thumbwheel
down.
