Driving -> REVERSE SENSING SYSTEM (IF EQUIPPED) for Your Ford Explorer SUV Third Generation (2002-2005)

Driving  
Do not rock the vehicle if the engine is not at normal operating  
temperature or damage to the transmission may occur.  
Do not rock the vehicle for more than a minute or damage to the  
transmission and tires may occur, or the engine may overheat.  
REVERSE SENSING SYSTEM (IF EQUIPPED)  
The Reverse Sensing System (RSS) sounds a tone to warn the driver of  
obstacles near the rear bumper when the R (Reverse) is selected and the  
vehicle is moving at speeds less than 5 km/h (3 mph). The system is not  
effective at speeds above 5 km/h (3 mph) and may not detect certain  
angular or moving objects.  
To help avoid personal injury, please read and understand the  
limitations of the reverse sensing system as contained in this  
section. Reverse sensing is only an aid for some (generally large and  
fixed) objects when moving in reverse on a flat surface at “parking  
speeds”. Inclement weather may also affect the function of the RSS;  
this may include reduced performance or a false activation.  
To help avoid personal injury, always use caution when in R  
(Reverse) and when using the RSS.  
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  
the vehicle. The system may not detect smaller objects, particularly  
those close to the ground.

Driving  
The RSS detects obstacles up to 2  
meters (6 ft.) from the rear bumper  
with a decreased coverage area at  
the outer corners of the bumper,  
(refer to the figures for approximate  
zone coverage areas). As you move  
closer to the obstacle, the rate of  
the tone increases. When the  
obstacle is less than 25.0 cm (10  
in.) away, the tone will sound  
continuously. If the RSS detects a  
stationary or receding object further  
than 25.0 cm (10 in.) from the side  
of the vehicle, the tone will sound  
for only three seconds. Once the  
system detects an object  
approaching, the tone will sound  
again.  
The RSS automatically turns on  
when the gear selector is placed in  
R (Reverse) and the ignition is ON.  
An RSS control on the instrument  
panel allows the driver to turn the  
RSS on and off. To turn the RSS off,  
the ignition must be ON, and the  
gear selector in R (Reverse). An  
indicator light on the control will  
OFF  
illuminate when the system is turned off. If the indicator light illuminates  
when the RSS is not turned off, it may indicate a failure in the RSS.  
Keep the RSS sensors (located on the rear bumper/fascia) free  
from snow, ice and large accumulations of dirt (do not clean the  
sensors with sharp objects). If the sensors are covered, it will  
affect the accuracy of the RSS.  
If your vehicle sustains damage to the rear bumper/fascia, leaving  
it misaligned or bent, the sensing zone may be altered causing  
inaccurate measurement of obstacles or false alarms.
