Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it wor ks
The acoustic park assist warning system (4 -channel acoustic park
assist) uses ultrasonic sensors to warn you when you are
backing
your vehicle close to an obstac le . The system 's 4 sensors are located
inside the rear bumper.
A cti va ting
The rea r acoustic park ass ist is activa ted whenever you shift into
Re verse . You will hear a warn ing tone when the system is on.
Reverse
With the car backing up in reverse gear, the collision warning sound
se ts in at the fo llowing
approximate d istances to obstacles:
st raight a ft 5ft(
1.5ml
a ngl ing aft of f ve hicle corners 2 ft (0.6 ml
As the distance shr inks, the time interval between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining
d istance to an obstacle c loses to less than about 1 ft. (0.3 ml. The
steady tone cautions you that you have backed up hazardously
close and you risk co llis ion by back ing up any furt her .
Malfunction s in the system
If a warning tone is audible for about five seconds when you turn on
the ignition, there is a ma lfunction in the system . Have the prob lem
corrected by your authorized Aud i dealer.
