Condition

Some customers may comment on a windshield crack. Ask the customer to provide additional information about the crack.

•	If cracking is not at an edge, how far in and where from a reference point, does the crack start?

•	What direction does the crack run (horizontal, vertical or diagonal)?

Take digital pictures of the stress crack. If you do not have a digital camera, use the provided windshield graphic to indicate the location of the crack in the windshield.

Important: If the stress crack originates from the bottom portion of the windshield, call Ron Paterson at 519-521-9980. It may be necessary for someone from the Plant or Engineering to inspect the vehicle prior to repairs being made.
