Important: 
   •  Use adhesion promoter to ensure adequate bonding of the coupling.    •  To obtain maximum adhesion between the new mobile antenna couplings  
 and the glass surface, the couplings and the glass must be kept  dry and    above
 15°C (60°F) during installation. Allow 6 to 8 hours, at 15°C    (60°F),
for the adhesive to cure after installation. Otherwise, the  new   couplings may not
adhere.    •  Do not attempt to reinstall the original cellular antenna exterior   
coupling or inner coupling using any type of glue, adhesive tapes, etc. Doing    
 so may eliminate the cellular signal transfer through the glass and reduce      the
maximum performance of the system, including the air bag deployment    notification. 
Notice: If you use a razor blade or other sharp tool in order to remove the adhesives or foreign objects from the inside of the rear window, use the blade carefully. Damage to the grid lines may result.
Follow the Glass Adhesion Promoter instructions on the product label.
Important: 
   •  Align the inner and outer antenna couplings.    •  Do not touch the adhesive backing on the antenna coupling. 
Hold pressure on the outer coupling (5) for 10-30 seconds.
