Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers are turned
on and have completed eight wipe cycles within
four minutes.
When the ignition is turned to OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps 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 210.
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.

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior lamps,
trunk lamp, glove box lamp, or the garage door
opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door or trunk is opened, or the
courtesy lamp switch is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will time out after 10 minutes,
if they are manually turned on before the ignition
is off.
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.
202

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 444. 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/retailer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air
brakes on a very large truck or other
mechanical devices that interfere with
UFRPA performance.
When UFRPA is disabled without driver action
and the driver attempts to turn UFRPA back
on using the Driver Information Center (DIC),
the PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions
and blind spots.
For Driver Information Center messages related
to UFRPA, seeDIC Warnings and Messages
on page 246.
If the bumper is damaged, your UFRPA system
may not work properly. Take the vehicle to
your dealer/retailer to repair the system.

SERVICE A/C SYSTEM
This message displays when the air delivery mode
door or the electronic sensors that control the air
conditioning and heating systems are no longer
working. Have the climate control system serviced
by your dealer if you notice a drop in heating and air
conditioning efficiency.
SERVICE BATTERY CHARGING
SYSTEM
This message displays when a problem with the
charging system has been detected. The charging
system light also displays on the instrument
panel cluster. SeeCharging System Light on
page 229for more information. Have your vehicle
serviced by your dealer.

the anti-lock brake system warning light may also
be displayed on the instrument panel cluster.
SeeBrake System Warning Light on page 229andAnti-Lock Brake System Warning Light on page 230
for more information. If this happens, stop as soon
as possible and turn off the vehicle. Restart the
vehicle and check for the message on the DIC
display. If the message is displayed or appears
again when you begin driving, the brake system
needs service. See your dealer as soon as
possible. SeeBrakes on page 387for more
information.
SERVICE BRAKE SYSTEM
This message displays if the ignition is on to
inform the driver that the brake uid level is low.
Have the brake system serviced by your dealer as
soon as possible.

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 PRESS
VTO 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.
