The sensors may be picking up the ground. Use the supplied shims to angle the sensors
back up a little bit to direct them away from the ground.

If you are installing on a vehicle with a metal bumper (Most likely a truck) then you may
need to use a specific system for that vehicle called a CA-5009.II.MBS. This kit is the
exact same system but comes with sensors specifically designed for use on metal
bumpers.
Please note that certain weather or road conditions can sometimes have an effect on the
system’s operation as well. Heavy rain, hail, ice and snow can cause the unit to give false
readings as well as extreme hot or cold weather. False warnings due to weather conditions are
rare but can sometimes happen.
Other things that can cause false warnings are smooth sloped surfaces, bushes, gravel roads or
uneven bumpy road surfaces. Although false readings due to these types of situations are also
rare, they have been know to happen and can sometimes occur.
