before purchasing to make sure the kit works with your vehicle.

Important Notes
Before final installation, test the wiring connections to make sure the unit is connected
properly and the system works.
Use only the parts included with the unit to ensure proper installation. The use of
unauthorized parts can cause malfunctions.
Consult with your nearest dealer if installation requires the drilling of holes or other
modifications to your vehicle.
Install the unit where it does not interfere with driving and cannot injure passengers during
a sudden or emergency stop.
If the installation angle exceeds 30' from horizontal, the unit might not give optimum
performance.
