Vehicle Personalization 0162.
The windshield washer reservoir is
used for the windshield and the rear
window. Check the fluid level in the
reservoir if either washer is not
working. See Washer Fluid 0300.
Compass
The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak,
and vehicle speed information.
The compass system is designed to
operate for a certain number of
miles or degrees of turn before needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system
will automatically determine when a
GPS signal is restored and provide
a heading again.

IntelliBeam System
If equipped, this system turns the
vehicle's high-beam headlamps on
and off according to surrounding
traffic conditions.
The system turns the high-beam
headlamps on when it is dark
enough and there is no other traffic
present.
This light comes on in the
instrument cluster when the
IntelliBeam system is enabled.
Turning On and Enabling

The system only activates the high
beams when driving over 40 km/h
(25 mph).
There is a sensor near the top
center of the windshield that
automatically controls the system.
Keep this area of the windshield
clear of debris to allow for best
system performance.
The high-beam headlamps remain
on, under the automatic control,
until one of the following situations
occurs:
.
The system detects an
approaching vehicle's
headlamps.
. The system detects a preceding
vehicle's taillamps.
. The outside light is bright
enough that high-beam
headlamps are not required.

IntelliBeam is reactivated.
See Headlamp High/Low-Beam
Changer 0176 and
Flash-to-Pass 0176.
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.
