Warranty Conditions:

This warranty is against defective materials or workmanship. The warranty is void if the product has been damaged by accident,unreasonable use, neglect, improper service/installation/removal,modifications, acts of God, normal wear and tear or other causes not arising out of defective materials or workmanship. Consequential and incidental damages are not covered under this warranty.

WIND WHIP DAMAGE Tarps must be secured at all points when vehicle is in motion. An unsecured tarp will flap, resulting in damage to the fabric.
IMPROPER CLEANING It is recommended to use the tested and approved Extang Tonno Tonic or clean with soap and water only. Do not use vinyl conditioners (i.e. Armor All) because they will shrink the vinyl.
OVERLOADING OF CARGO Cargo should not touch the tonneau at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric or panels and damage it.
DRIVING WITH PANELS OPEN OR IMPROPERLY SECURED ON ALL FOLDING TONNEAUS Prior to vehicle operation, clamps must be tightly secured so that clamp lips tightly grip the inner bedside metal surface.
OPEN POSITION: Tonneau must be completely folded and secured with BOTH buckles.
CLOSED POSITION: Tonneau must be completely flat and secured at all 4 clamps.
OPENING PANELS WITHOUT REMOVAL OF DEBRIS ON ALL FOLDING TONNEAUS Top of tonneau MUST be free of foreign material including snow and ice before opening panels or severe damage may result.
TOWING Do NOT tow your vehicle from the rear with any Extang tonneau cover on your truck.
