2010 GMC YUKON XL parking sensors

Ultrasonic Parking Assist
This feature uses sensors on the rear bumper to
detect objects while parking the vehicle. URPA comes
on automatically when the shift lever is moved into
R (Reverse) and operates at speeds less than 8 km/h
(5 mph). URPA uses audio beeps to provide distance
and system information.
Keep the sensors on the vehicle's rear bumper clean to
ensure proper operation.
The system can be disabled by pressing the rear park
aid disable button located next to the radio.
SeeUltrasonic Rear Parking Assist (URPA)
on
page 3‑58for more information.
Power Outlets
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two under the climate controls, one inside the
center floor console, one on the rear of the center floor
console and one accessory power outlet in the rear
cargo area on the passenger side. The accessory power outlets are powered, even with
the ignition off. Continuing to use accessory power
outlets while the ignition is in LOCK/OFF may cause
the vehicle's battery to run down.
Universal Remote System
The Universal Home Remote System allows for garage
door openers, security systems, and home automation
devices to be programmed to work with these buttons in
the vehicle.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking
Assist (URPA) system, it operates at speeds less than
8 km/h (5 mph), and assists the driver with parking and
avoiding objects while in R (Reverse). The sensors on
the rear bumper are used to detect the distance to an
object up to 2.5 m (8 ft) behind the vehicle, and at least
25.4 cm (10 in) off the ground.
{WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
.Objects that are below the bumper,
underneath the vehicle, or if they are too
close or far from the vehicle
.Children, pedestrians, bicyclists, or pets.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you rotate your vehicle's tires or replace one
or more of the TPMS sensors, the identification codes
will 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 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 inflation 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
gauge, or a key.
You have two minutes to match the first tire/wheel
position, and five minutes overall to match all four
tire/wheel positions. If it takes longer than two minutes,
to match the first tire and wheel, or more than
five minutes to match all four tire and wheel positions
the matching process stops and you need to start over.The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Press
QandKon the Remote Keyless
Entry (RKE) transmitter at the same time for
approximately five seconds. The horn sounds
twice to signal the receiver is in relearn mode and
TIRE LEARNING ACTIVE message displays on
the DIC screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, confirms that
the sensor identification code has been matched to
this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
