Reverse Park Control
General
The function of the Reverse Park Control (RPC) is
to provide an audible warning to the driver of the
distance to obstacles near the rear bumper of the
vehicle when reversing. The system operates
through four ultrasonic sensors that send out
beams covering the area behind the vehicle.
These beams are reflected by obstructions behind
the vehicle and re-enter the sensors. The reflected
beam information is processed by the reverse
park control module (RPCM) to calculate the

RPC Speaker distance of the obstruction. The sounder is then
activated and gives the appropriate warning signal
starting from an intermittent beep (at
approximately 0.8 meters) up to the continuous
ÔstopÕ tone (at approximately 0.2 meters).
The sensors are fitted, equally spaced, across the
rear bumper. The system is activated when the
gear selector is moved to the reverse position
whilst the engine is running. It can be switched off
by pressing the switch in the overhead console. A
