Parking Aid - Reverse Sensing System

PARKING AID - REVERSE SENSING SYSTEM

The parking aid system consists of the following:
- four ultrasonic parking aid sensors (located in the rear bumper)
- parking aid speaker (supplies an audible warning tone [located on the parking aid module])
- parking aid module (located behind the jack storage panel)
- parking aid disable assist switch (located in the instrument panel)

The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper. The parking aid system is enabled when the vehicle ignition is in RUN and REVERSE gear is selected. The system can be disabled through the parking aid switch located in the instrument panel.

The parking aid system detects objects by the use of four ultrasonic sensors mounted in the rear bumper. The ultrasonic field is emitted in a semicircular area around the rear of the vehicle. The parking aid sensors can detect objects approximately 1.8 m (5.9 ft) to the rear of the vehicle, 50 cm (1.6 ft) to the rear side of the vehicle, and 16 cm (6 in) above ground. A 750 Hz variable warning tone is generated from the parking aid speaker attached to the parking aid module. The parking aid speaker increases its warning tone rate as the vehicle gets closer to an obstacle. When an object is detected within 25 cm (10 in) of the sensors, the warning tone becomes continuous.
