Front Sensing System
The front sensors are active when the gearshift is in any position other
than P (Park) or N (Neutral) and the vehicle speed is below 8 mph
(13 km/h).
A. Coverage area of up to 27 inches
(70 centimeters) from the front of
the vehicle and about 6–9 inches
(15–23 centimeters) to the side of
the front end of the vehicle. Refer
to the reverse sensing section for
details on coverage area.
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 inches (30
centimeters) from the front of the vehicle and, at the same time, an
obstacle is only 6 inches (15 centimeters) from the rear of the vehicle,
the lower pitched tone sounds.
• An alternating warning sounds from the front and rear if there are
objects at both bumpers that are closer than 10 inches (25
centimeters).
For specific information on the reverse sensing portion of the system,
refer to that section.
