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 timeout after 10 minutes, if
they are manually turned on before the ignition
is off.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help
you park while in Reverse (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The
URPA system detects objects that are close to the
rear of 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 8 feet
(2.5 m) behind your vehicle. The URPA sensors
determine how close these objects are from
your bumper within this area.

light will come on the URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
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 into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
The ultrasonic sensors need to be kept clean.
So, be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush. For
cleaning instructions, seeWashing Your
Vehicle on page 468. If the DIC still displays the
PARK ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), 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 URPA performance.
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.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer/retailer to repair the system.

SERVICE PARK ASSIST
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system, this message displays
if there is a problem with the URPA system. Do
not use this system to help you park. See
Ultrasonic Rear Parking Assist (URPA) on
page 188for more information. See your
dealer/retailer for service.
SERVICE POWER STEERING
This message displays when a problem is
detected with the power steering system. When
this message is displayed, you may notice that the
effort required to steer the vehicle increases or
feels heavier, but you will still be able to steer the
vehicle. Have your vehicle serviced by your
dealer/retailer immediately.
SERVICE STABILITRAK
This message displays if there is a problem with
the StabiliTrak®system. If this message appears,
try to reset the system. Stop; turn off the engine
for at least 15 seconds; then start the engine
again. If this message still comes on, it means
there is a problem. See your dealer/retailerfor service. The vehicle is safe to drive, however,
you do not have the bene t of StabiliTrak
®,so
reduce your speed and drive accordingly.
SERVICE THEFT DETERRENT SYSTEM
This message displays when there is a problem
with the theft-deterrent system. The vehicle may or
may not restart so you may want to take the
vehicle to your dealer/retailer before turning off the
engine. SeePASS-Key
®III+ Operation on
page 121for more information.
SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the
warning comes on in about 20 minutes. A sensor
would be missing, for example, if you put
different wheels on your vehicle without
transferring the sensors. If the warning comes on
and stays on, there may be a problem with the
TPM. See your dealer/retailer.

Resetting the TPMS Identi cation
Codes
Each TPMS sensor has a unique identi cation
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identi cation codes need to be matched to the
new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver side front tire, passenger side front
tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum in ation
pressure indicated on the tire’s sidewall. To
decrease air-pressure out of a tire you can use
the pointed end of the valve cap, a pencil-style air
pressure gage, or a key.
You 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, ormore than ve minutes to match all four tire and
wheel positions, the matching process stops
and you will need to start over.
The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Using the DIC, press the vehicle information
button until the PRESS
VTO RELEARN
TIRE POSITIONS message displays. If your
vehicle does not have the DIC buttons,
press the trip odometer reset stem located on
the instrument panel cluster until the
RELEARN TIRE POSITIONS message
displays.
4. If your vehicle has the DIC buttons, press the
set/reset button. The horn sounds twice to
indicate the TPMS receiver is ready, and the
TIRE LEARNING ACTIVE message
displays. If your vehicle does not have the
DIC buttons, press and hold the trip odometer
reset stem until the horn chirps twice and
the TIRE LEARNING ACTIVE message
is displayed.
