Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds.
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the windshield wipers
are 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.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transaxle is not in PARK (P) (United
States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-44.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the
DRL are being used. Your instrument panel will not be
lit up either.
When automatic lighting is on and it is dark enough
outside, the turn signal lamps will turn off and normal
low-beam headlamp operation will occur.
When automatic lighting is on and it is bright enough
outside, the regular lamps will go off, and the DRL
will take over. If you start your vehicle in a dark
garage, the automatic headlamp system will come on
immediately. Once you leave the garage, it will take
approximately one minute for the automatic headlamp
system to change to DRL if there is light outside. During
that delay, your instrument panel cluster may not be
as bright as usual. Make sure your instrument
panel brightness knob is in the full bright position.
SeeInstrument Panel Brightness on page 3-36.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the
fog lamps were turned on instead, the DRL will still
deactivate.

Ultrasonic Front and Rear Parking
Assist (UFRPA)
If your vehicle is equipped, the Ultrasonic Front and
Rear Parking Assist (UFRPA) system is designed
to help you park. It operates only at speeds less than
5 mph (8km/h). UFRPA helps make parking easier and
helps you avoid colliding with objects such as parked
vehicles. The UFRPA system detects objects that
are close to the vehicle which are at least 10 inches
(25.4 cm) off the ground and below hood or trunk level.
The system detects objects up to 4 feet (1.2 m) in
front of the vehicle and up to 8 feet (2.5 m) behind your
vehicle. UFRPA determines how close these objects
are from your bumpers within this area. Four ultrasonic
sensors on the front and rear bumpers are used to
detect the distance to the object.
{CAUTION:
Even with the Ultrasonic Front and Rear Park
Assist system, the driver must check carefully
before backing up or moving forward while
parking. The system does not operate above
speeds of 5 mph (8 km/h). The system does
not detect objects that are more than 4 feet
(1.2 meters) in front of the vehicle and more
than 8 feet (2.5 meters) behind the vehicle.
This detection distance limit may be reduced
during warm weather or high humidity. Also,
the system does not detect objects that are
below your bumper, underneath your vehicle,
or some objects very close to the vehicle.
The system is not designed to detect children,
pedestrians, bicyclists, or pets.
So, unless you check carefully behind and in
front of your vehicle while you are parking
they could be injured or killed.
Whether or not you are using front and rear
park assist, always check carefully in front and
behind your vehicle before moving forward or
backing up and then watch closely as you do.
3-38

When you are backing the vehicle and objects are
detected at the same time near both the front and rear
bumpers, both color-coded light displays will notify
you of objects close to each bumper. If there are objects
detected near both bumpers, the beeps will only be
sounded to notify that objects are close to the rear
bumper. However, if while you are backing and an object
comes within 1 ft (0.3 m) of the front bumper, and at
the same time there is another object further than
1 ft (0.3 m) from the rear bumper, then the beeps will
only be sounded to notify you of the closer object that is
near the front bumper.
When the System Does Not Seem to
Work Properly
If the UFRPA system will not activate due to a temporary
condition, the message PARKING ASSIST OFF will
be displayed on the DIC and a red light will be shown on
the rear UFRPA display when the shift lever is moved
into REVERSE (R). This occurs under the following
conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-72.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle. If the
attached objects are removed from your vehicle
before the start of your next drive, the system will
return to normal operation unless an object is
detected when the vehicle is shifted out of park.
If this occurs, you will have to wait until the vehicle
is driven forward above 15 mph (25 km/h) before
UFRPA will return to normal operation.
A bicycle or an object is attached to the front
bumper during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next drive,
the system will return to normal unless an object
is detected when the vehicle is shifted out of park.
If this occurs, UFRPA will return to normal
operation when the vehicle is driven forward
above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your Vehicle
on page 5-86. If after cleaning the front and rear
bumpers and driving forward at a speed of
at least 15 mph (25 km/h), the DIC displays the
PARKING ASSIST OFF message, see your dealer.

Resetting the TPMS Sensor
Identication Codes
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors,
rotate the vehicle’s tires, or install a full-size spare
that has a TPMS sensor, the sensor’s identication
codes will need to be matched to the new tire/wheel
position. Each tire/wheel position is matched to
the TPMS sensor using a TPMS diagnostic tool. See
your GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. When increasing the tire’s air pressure,
do not exceed the maximum tire pressure indicated on
the tire’s sidewall.
You will have two minutes to match the rst tire/wheel
position, and ve minutes overall, to match all
four tire/wheel positions. If it takes longer than
two minutes, to match the rst tire and wheel, or
more than ve minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Press the Driver Information Center (DIC) vehicle
information button until the RELEARN TIRE
POSITIONS displays.
4. Press the set/reset button to allow the system to
learn the tire positions. The horn will sound twice
to indicate that the TPMS is ready, and then
the message TIRE LEARNING ACTIVE will display.
The sensor matching process can begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, conrms that the
sensor identication code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a pencil-style
air pressure gage or a key.
