2009 CHEVROLET TAHOE display

The display is located near
the passenger side rear
window and can be
seen by looking over your
right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If the vehicle is above this speed, the
red light on the rear display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below liftgate level. Objects
must also be within 8 feet (2.5 m) from the rear
bumper. This distance may be less during warmer or
humid weather.A single beep will sound the rst time an object is
detected between 40 inches (1 m) and 8 feet (2.5 m)
away. Beeping will occur continuously when the vehicle
is at 23 inches (0.6 m) or closer to an object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:

The system can be
disabled by pressing the
rear park aid disable button
located next to the radio.
The indicator light will come on and PARK ASSIST OFF
displays on the Driver Information Center (DIC) to
indicate that URPA is off, seeDIC Warnings and
Messages on page 3-64for information about clearing
the message.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-109.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the liftgate during the
last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the
system.

{CAUTION:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
Vehicles outside the side blind zones which
may be rapidly approaching.
Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury, or
death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind
zone, amber SBZA displays light up in the side mirrors.
This indicates that it may be unsafe to change lanes.
Before making a lane change, always check the SBZA
display, check the outside and rearview mirrors, look
over your shoulder for vehicles and hazards, and
use the turn signal.
2-59

SBZA Detection Zones
The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 11 ft. or
3.5 m. This zone starts at each side mirror and goes
back approximately 16 ft. (5.0 m). The height of the zone
is approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m)
off the ground.
Use caution while changing lanes when towing a trailer,
as the SBZA detection zones do not change when a
trailer is towed.
How the System Works
When the vehicle is started, both outside mirror displays
will briey come on to indicate that the system is
operating. When the vehicle is moving forward, the left
or right side mirror SBZA display will light up if a
vehicle is detected in that blind zone. If the turn signal is
activated and a vehicle is also detected on the same
side, the SBZA display will ash to give you extra
warning not to change lanes.
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds
greater then 20 mph (32 km/h), SBZA displays may
come on when a vehicle you have passed remains in or
drops back into the detection zone.

SBZA can be disabled through the Driver Information
Center (DIC). SeeDriver Information Center (DIC)
on page 3-51for more information. If the SBZA
is disabled by the driver, the SBZA mirror displays will
not light up during normal driving.
When the System Does Not Seem To Work
Properly
Occasional missed alerts can occur under normal
circumstances and will increase in wet conditions. The
system does not need to be serviced due to an
occasional missed alert. The number of missed alerts
will increase with increased rainfall or road spray.
If the SBZA displays do not light up when the system is
on and vehicles are in the blind zone, the system
may need service. Take the vehicle to your
dealer/retailer.
SBZA is designed to ignore stationary objects; however,
the system may occasionally light up due to guard
rails, signs, trees, shrubs, and other stationary objects.
This is normal system operation, the vehicle does
not need service.SBZA does not operate when the left or right corners of
the rear bumper are covered with mud, dirt, snow,
ice, slush, or in heavy rainstorms. For cleaning
instructions, seeWashing Your Vehicle on page 5-109.
If the DIC still displays the SIDE BLIND ZONE SYS.
UNAVAILABLE message after cleaning the bumper, see
your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn
SBZA back on using the DIC. The SIDE BLIND ZONE
ALERT ON option will not be selectable if the
conditions for normal system operation are not met.
Until normal operating conditions for SBZA are met, you
should not rely upon SBZA while driving.

dealer/retailer.
Rear Vision Camera (RVC)
This vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{CAUTION:
The Rear Vision Camera (RVC) system does not
replace driver vision. RVC does not:
Detect objects that are outside the camera’s
eld of view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians, bicyclists, or pets.
Do not back the vehicle by only looking at the rear
vision camera screen, or use the screen during
longer, higher speed backing maneuvers or where
there could be cross-traffic. Your judged distances
using the screen will differ from actual distances.
So if you do not use proper care before backing up,
you could hit a vehicle, child, pedestrian, bicyclist,
or pet, resulting in vehicle damage, injury, or death.
Even though the vehicle has the RVC system,
always check carefully before backing up by
checking behind and around the vehicle.
