9-32 Driving and Operating
WARNING (Continued)
prevent injury, death, or vehicle
damage, even with URPA, always
check the area around the vehicle
and check all mirrors before
backing.
How the System Works
URPA comes on automatically when
the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below liftgate level. Objectsmust also be within 2.5 m (8 ft) from
the rear bumper. This detection
distance may be less during warmer
or humid weather.
Turning the System On and Off
The system can be disabled through
the Driver Information Center (DIC).
See
“Park Assist” underDriver
Information Center (DIC) on
page 5‑23 for more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARK ASSIST: If this
message occurs, take the vehicle to
your dealer to repair the system. PARK ASST BLOCKED SEE
OWNERS MANUAL:
This
message can occur under the
following conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑75.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.

.A tow bar is attached to the
vehicle.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Side Blind Zone
Alert (SBZA)
If available, the Side Blind Zone
Alert system is a lane changing aid
that assists drivers with avoiding
crashes that occur with vehicles in
the side blind zones.
{WARNING
SBZA does not detect vehicles
rapidly approaching outside of the
side blind zones, pedestrians,
bicyclists, or animals. Failure to(Continued)
WARNING (Continued)
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before
making a lane change, always
check mirrors, glance over your
shoulder, and use the turn
signals.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, 3.5 m (11 ft). This zone starts at each side
mirror and goes back approximately
5.0 m (16 ft). The height of the zone
is approximately between
0.5 m (1.5 ft) and 2.0 m (6 ft) off the
ground.
Use caution while changing lanes
when towing a trailer, as the SBZA
detection zones that extend back
from the sides of the vehicle do not
move further back when a trailer is
towed.
How the System Works
The SBZA symbol lights up in the
side mirrors when the system
detects a vehicle in the side blind
zone, indicating it may be unsafe to
change lanes. Before making a lane
change, check the SBZA display,
check all mirrors, glance over your
shoulder, and use the turn signals.

Black plate (34,1)Acadia/Acadia Denali Owner Manual - 2013 - crc2 - 12/11/12
9-34 Driving and Operating
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is moving forward, the left or
right side mirror 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 display will flash
to give you extra warning not to
change lanes.
At speeds greater then 32 km/h
(20 mph), SBZA displays may come
on when approaching or passing
other vehicles. SBZA displays may
come on when a passed vehicle
remains in or drops back into the
detection zone. SBZA can be disabled through the Driver
Information Center (DIC). See
Driver
Information Center (DIC) on
page 5‑23. If SBZA is disabled by
the driver, the SBZA mirror displays
will not light up.
When the System Does Not Seem
To Work Properly
Missed alerts can occur under
normal circumstances and will
increase in wet conditions. The
system does not need to be
serviced. 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.
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.
SBZA does not operate when the
SBZA sensors in the left or right
corners of the rear bumper are covered with mud, dirt, snow, ice,
slush, or in heavy rainstorms. For
cleaning instructions, see
“Washing
the Vehicle” underExterior Care on
page 10‑75. If the DIC still displays
the SIDE DETECTION SYS
TEMPORARILY OFF message after
cleaning the bumper, see your
dealer.
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, it cannot be turned back on.
The SIDE BLIND ZONE ALERT ON
option will not be selectable if the
conditions for normal system
operation are not met.

9-44 Driving and Operating
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:
Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering. When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
