system. During normal operation, the DRL
will turn on lights when the headlights are
turned off, engine is on, and the park
brakes are disengaged. The override
switch will turn the DRL off in these
instances. The DRL is also turned off when
the headlights are turned 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. Failure to com-
ply may result in personal injury, prop-
erty damage or death.
If the headlight switch is turned OFF, the
DRL system engages automatically after
the engine starts and you release the
parking brake. If the headlight switch is
ON, the DRL system is overridden, and
headlights operate normally
. Also, the DRL
is temporarily turned off during engine
cranking.
