Object Detection Systems; Ultrasonic Parking Assist - GMC Acadia 2013 Owner's Manual

Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
Press and hold the SET button
on the steering wheel until the
lower speed desired is reached,
then release it.
To slow down in small amounts,
press the SET button briefly.
Each time this is done, the
vehicle goes about 1.6 km/h
(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase vehicle speed. When you
take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep the
vehicle speed down. When the
brakes are applied the cruise control
is disengaged.
Ending Cruise Control
There are three ways to end cruise
control:
Step lightly on the brake pedal.
Press the button.
To turn off the cruise control,
press on the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
or if the ignition is turned off.

Parking Assist (URPA) system
assists the driver with parking and
avoiding objects while in

speeds less than 8 km/h (5 mph).
The sensors on the rear bumper are
used to detect objects up to
2.5 m (8 ft) behind the vehicle, and
at least 25 cm (10 in) off the ground
and below liftgate level.
WARNING
The URPA system does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
