x(Delay Adjustment):Use this band to set the
length of the delay between wipes when using the delay
feature. The closer you move the band toward mist,
the longer the delay. The windshield wiper lever must be
in delay for this feature to work.
6(Low Speed):Put the lever in this position for
slow, steady wiping cycles.
1(High Speed):Put the lever in this position for
rapid wiping cycles.
If the windshield wipers are in use for about six seconds
while you are driving, the exterior lamps will come on
automatically if the exterior lamp control is in AUTO.
SeeWiper Activated Headlamps on page 3-37for more
information.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
gently loosen or thaw them. If the blades do become
damaged, install new blades. For more information, see
Windshield Wiper Blade Replacement on page 5-51.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior side of the windshield behind the
rearview mirror. It is used to automatically operate the
wipers by monitoring the amount of moisture build-up on
the windshield. Wipes occur as needed to clear the
windshield depending on driving conditions and
the sensitivity setting. In light rain or snow, fewer wipes
will occur. In heavy rain or snow, wipes will occur
more frequently. The Rainsense™ wipers operate in a
delay mode as well as a continuous low or high
speed as needed. If the system is left on for long periods
of time, occasional wipes may occur without any
moisture on the windshield. This is normal and indicates
that the Rainsense™ system is activated.
To activate the Rainsense™ system, turn the wiper
band to delay mode and select one of the four sensitivity
levels indicated on the wiper stalk. The position
closest to off is the lowest sensitivity setting, level one.
This allows more rain or snow to collect on the
windshield between wipes. Turning the wiper band away
from you to higher sensitivity levels increases the
sensitivity of the system and frequency of wipes. The
highest sensitivity setting, level four is closest to low.

Intellibeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read this
entire section before using it.
Intellibeam™ is an enhancement to your vehicle’s
headlamp system. Using a digital light sensor on your
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The Intellibeam™ system will turn your high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the Intellibeam™ system is
enabled.
Turning On and Enabling Intellibeam™
O(On/Off):Quickly press and release the on/off
button on the inside rear view mirror. The indicator on
the mirror will ash once to let you know the system has
been turned on. Once the system has been turned
on, it will remain on each time the vehicle is started.
Additionally, the Intellibeam™ system must be enabled.
3-34
To enable the Intellibeam™ System, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-72. Your vehicle is equipped with variable
intensity high-beams. The high-beam indicator on the
instrument panel will illuminate as soon as the
high-beams start to come on, and will remain on until
the high-beams have completely turned off. All
Intellibeam™ equipped vehicles, however, will quickly
turn off the high-beams if the system detects the sudden
presence of vehicle lights ahead.
Driving with Intellibeam™
Intellibeam™ will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will remain on, under the
control of Intellibeam™, until any of the following
situations occur:
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.
The high-beam headlamps are manually turned on
or you use the ash-to-pass feature. SeeHeadlamp
High/Low-Beam Changer on page 3-9and
Flash-to-Pass on page 3-13.
When either of these conditions occur, the
Intellibeam™ feature will be temporarily disabled
until the high-beam stalk is returned to the neutral
position.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, Intellibeam™ will be disabled
until the control is turned back to the AUTO position
and the AUTOMATIC LIGHTS ON message is
displayed on the DIC.
The Intellibeam™ system is turned off at the inside
rearview mirror.
The vehicle’s speed drops below 15 mph (24 km/h).
Intellibeam™ may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because of
any of the following:
The others vehicle’s lamp(s) are missing, damaged,
obstructed from view or otherwise undetected.
The other vehicle’s lamp(s) are covered with dirt,
snow and/or road spray.
3-35
The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked or
obstructed by something that blocks the view of the
Intellibeam™ light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze or other obstructions.
Your vehicle is loaded such that the front end of the
vehicle points upward, causing the Intellibeam™
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You may need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting Intellibeam™
at the Rearview Mirror
Intellibeam™ can be disabled and reset to the original
factory setting by using the controls on the inside
rearview mirror.
O(On/Off):To disable the system, press and hold
this button on the inside rearview mirror for three
seconds and release it after the indicator on the inside
rearview mirror ashes two times. This lets you
know that Intellibeam™ has been turned off and will not
come back on until the system has been reset.
To reset the system, quickly press and release this
button on the inside rearview mirror. The indicator on the
inside rearview mirror will ash one time to indicate
that Intellibeam™ has been reset.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the light ashes three times.
If you accidentally activate this, the vehicle’s setting
will automatically be reset each time the ignition
is turned off and then on again; otherwise, refer to the
text above for resetting the system.

Cleaning the Intellibeam™ Light Sensor
The light sensor is located
on the inside of the vehicle
in front of the inside
rearview mirror.
Clean the light sensor window, periodically, using glass
cleaner on a soft cloth. Gently wipe the sensor
window. Do not spray glass cleaner directly on the
surface of the sensor window.
Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. For this feature to work, automatic
lighting must be enabled. SeeHeadlamps on page 3-33
for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off if the windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-71for additional
information.
3-37
The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system turns on, the
three lights on the display will illuminate for one and
a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R) at
a speed greater than 3 mph (5 km/h), the red light
will ash to remind you that the system does not work
at a speed greater than 3 mph (5 km/h).If an object is detected at a REVERSE (R) speed of
less than 3 mph (5 km/h), one of the following will occur:
Description English Metric
Amber light 5 ft 1.5 m
Amber/amber lights 40 in 1.0 m
Amber/amber/red lights &
continuous chime20 in 0.5 m
Amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
URPA cannot detect objects that are above trunk level.
In order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may affect
system performance include things like the vibrations
from a jackhammer or the compression of air brakes on a
very large truck. If after cleaning the rear bumper and
then driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
3-48
The rear window defogger will turn off about 10 minutes
after the button is pressed, or if the vehicle’s speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about ve minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger button is on.
Notice:Using a razor blade or sharp object to
clear the inside rear window may damage the rear
window defogger. Repairs would not be covered
by your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the air ow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the air ow.Turn the thumbwheel to the right to open the outlets
completely and allow the maximum amount of air
to enter your vehicle. Turn the thumbwheel to the left to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the air ow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-58.

Highway Hypnosis
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on
the road, the drone of the engine, and the rush of
the wind against the vehicle that can make you sleepy.
Do not let it happen to you! If it does, your vehicle
can leave the road in less than a second, and you
could crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in at or rolling terrain.
