Driving and Operating
The system consists of four
ultrasonic parking sensors in the
rear bumper and four ultrasonic
parking sensors in the front bumper
(if equipped).

Danger
The Parking Assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 11 km/h
(7 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
Note
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system is activated automatically.
An obstacle is indicated by acoustic
warnings. The interval between the
warnings becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the acoustic warning sounds
continuously.
Note
The acoustic warning sounds stop
to work if vehicle stop for 3 seconds
or more (except in continuous
sound)
Deactivation
The system is deactivated
automatically when:
.
The vehicle is driven above
11 km/h
—
front and rear parking
assist is deactivated.
.
The reverse gear is disengaged
—
rear parking assist is
deactivated.
.
A fault in the system occurs.
The system can be manually turned
off by pressing the

instrument panel while Parking
Assist is on.

with no obstacles in a range of
2 meters of the rear bumper.
2. Apply the parking brake firmly.
3. Turn the ignition key to
ON

If there is no acoustic
signal: Check the power
supply of the kit module, by

given followed shortly after
by an almost continuous
acoustic signal, it indicates
a fault sign: Seek the
assistance of a Chevrolet
dealer.
