The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps
because of any of the following:
The other vehicle's lamps are
missing, damaged, obstructed
from view, or otherwise
undetected.
The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
The other vehicle's lamps cannot
be detected due to dense
exhaust, smoke, fog, snow, road
spray, mist, or other airborne
obstructions.
The vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view
of the light sensor.
The vehicle is loaded such that
the front end points upward,
causing the light sensor to aim
high and not detect headlamps
and taillamps.
The vehicle is being driven on
winding or hilly roads.
The automatic high-beam
headlamps may need to be disabled
if any of the above conditions exist.

Lighting

Flash-to-Pass

This feature lets you use the
high-beam headlamps to signal a
driver in front of you that you want
to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low beam,
the high-beam headlamps will turn
on. Depending on the type of
headlamp, they will either turn off
after a short duration or stay on as
long as you hold the lever toward
you. The high-beam indicator on the
instrument cluster will come on.
Release the lever to return to
normal operation.
