2007 GMC YUKON XL sensor

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. URPA determines how close
these objects are from your bumper within this area.
Ultrasonic sensors on the rear bumper are used to
detect the distance to the object.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully
before backing up. The system does not
CAUTION: (Continued)
CAUTION: (Continued)
operate above speeds of 5 mph (8 km/h).
The system does not detect objects 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
your vehicle while you are backing up,
they could be injured or killed.
Whether or not you are using rear park
assist, always check carefully behind your
vehicle before backing up and then watch
closely as you do.

The ultrasonic sensors are not 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 532. If the DIC still displays the
PARKING ASSIST OFF message after
cleaning the bumper and driving forward at a
speed of at least 15 mph (25 km/h), see your
dealer.
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.
When URPA is disabled without driver action
and the driver attempts to turn URPA 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
URPA, seeDIC Warnings and Messages on
page 254.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
With accessory power outlets you can plug in
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
Your vehicle will have two accessory power
outlets under the climate controls, one on the back
of the oor console and a additional accessory
power outlet in the rear cargo area on the
passenger side.
To use the power outlet, lift the spring cap and
insert electrical 12V device plug. To close
the power outlet, remove 12V electrical device
plug and the spring cap will close.
Certain power accessory plugs may not be
compatible to the accessory power outlet and
could result in blown adapter or vehicle fuses.

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The current
delivery mode and fan speed will also be
displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will illuminate
in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
74°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting as
necessary. If you choose the temperature
setting of 60°F (15°C), the system will remain at
the maximum cooling setting. If you choose the
temperature setting of 90°F (32°C), the system
will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based
on sun load and also turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air
is available. The length of delay depends on
the engine coolant temperature. Pressing the fan
switch will override this delay and change the
fan to a selected speed.

Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds
to remind the front passenger to buckle their safety
belt. The passenger safety belt light will also
come on and stay on for several seconds, then it
will ash for several more.
This chime and light will
be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensors, the airbag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, seeAirbag System on page 90.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
