PRINCIPLE OF OPERATION  
off when a MyKey is present. See Principle  
of Operation (page 54).  
WARNINGS  
Note: If you attach certain add-on devices  
such as a trailer or bike rack, the rear sensing  
system may detect that add-on device and  
therefore provide warnings. It is suggested  
that you disable the rear sensing system  
when you attach an add-on device to your  
vehicle to prevent these warnings.  
The sensing system warns the driver of  
obstacles within a certain range of your  
vehicle. The system turns on automatically  
whenever you switch the ignition on.  
To help avoid personal injury, please  
read and understand the limitations  
of the system as contained in this  
section. Sensing is only an aid for some  
(generally large and fixed) objects when  
moving on a flat surface at parking speeds.  
Certain objects with surfaces that absorb  
ultrasonic waves, surrounding vehicle's  
parking aid systems, traffic control  
systems, fluorescent lamps, inclement  
weather, air brakes, and external motors  
and fans may also affect the function of  
the sensing system; this may include  
reduced performance or a false activation.  
You can turn the system on or  
off by pressing the parking aid

button. If your vehicle does not

This system is not designed to  
prevent contact with small or moving  
objects. The system is designed to  
provide a warning to assist the driver in  
detecting large stationary objects to avoid  
damaging your vehicle. The system may  
not detect smaller objects, particularly  
those close to the ground.  
transmission into reverse (R). See General  
Information (page 91).  
If a fault is present in the system, a warning  
message appears in the information  
display. See Information Messages  
(page 95).  
Certain add-on devices such as large  
trailer hitches, bike or surfboard racks  
and any device that may block the  
normal detection zone of the system, may  
create false beeps.  
REAR PARKING AID  
The rear parking aid sensors automatically  
turn on when you shift into reverse (R).  
As your vehicle moves closer to the  
obstacle, the rate of the audible warning  
increases. When the obstacle is less than  
12 in (30 cm) away, the warning sounds  
continuously. If the system detects an  
object farther than 12 in (30 cm) from the  
corners of the bumper, the tone sounds for  
only three seconds. If the system detects  
an approaching object the warning sounds  
again.  
Note: Keep the sensors, located on the  
bumper or fascia, free from snow, ice and  
large accumulations of dirt. If the sensors  
are covered, the systems accuracy can be  
affected. Do not clean the sensors with  
sharp objects.  
Note: If your vehicle sustains damage to  
the bumper or fascia, leaving it misaligned  
or bent, the sensing zone may be altered  
causing inaccurate measurement of  
obstacles or false alarms.

E187330  
Coverage area of up to 28 in (70 cm) from  
the front bumper. There is decreased  
coverage area at the outer corners.  
E130178  
Coverage area of up to 6 ft (1.8 m) from  
the rear bumper. There is decreased  
coverage area at the outer corners of the  
bumper.  
The system sounds an audible warning  
when obstacles are near either bumper in  
the following manner:  
Objects detected by the front sensors  
are indicated by a high-pitched tone  
from the front of the vehicle.  
Objects detected by the rear sensors  
are indicated by a lower pitched tone  
from the rear of the vehicle.  
The sensing system reports the  
obstacle which is closest to the front  
or rear of the vehicle. For example, if  
an obstacle is 12 in (30 cm) from the  
front of the vehicle and, at the same  
time, an obstacle is only 6 in (15 cm)  
from the rear of the vehicle, the lower  
pitched tone sounds.  
The system detects certain objects while  
the transmission is in reverse (R) :  
Your vehicle is moving toward a  
stationary object at a speed of 3 mph  
(5 km/h) or less.  
Your vehicle is not moving, but a  
moving object is approaching the rear  
of your vehicle at a speed of 3 mph  
(5 km/h) or less.  
Your vehicle is moving at a speed of  
less than 3 mph (5 km/h) and a moving  
object is approaching the rear of your  
vehicle at a speed of less than 3 mph  
(5 km/h).  
An alternating warning sounds from  
the front and rear if there are objects  
at both bumpers that are closer than  
12 in (30 cm).  
FRONT PARKING AID  
The front parking aid sensors automatically  
turn on when you shift into reverse (R) or  
a forward gear.  
The front sensors are active when the  
transmission is in any position other than  
park (P) and the vehicle speed is below  
7 mph (12 km/h).  
The system provides warnings when your  
vehicle is moving or when your vehicle is  
stationary and the detected obstacle is  
less than 12 in (30 cm) away from the  
bumper.
