Headlights
02890
The headlights are controlled by the control panel
switch(es) showing the above symbol. When the head-
lights are ON, the dash lights, side, and tail lamps are also
on.
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 injury accident.
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 headlamp
switch is turned on, the DRL system is overridden
& headlamps operate normally.
