REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to notifying Landoll Manufacturing.
If NHTSA receives similar complaints, it may open an investigation, and if it
finds that a safety defect exists in a group of vehicles, it may order a recall and
remedy campaign. However, NHTSA cannot become involved in individual prob-
lems between you, your dealer, or Landoll Manufacturing.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-
800-424-9393 (or 366-0123 in Washington, D.C. area) or write to: NHTSA, U.S. De-
partment of Transportation, Washington, D.C. 20590. You can also obtain other in-
formation about motor vehicle safety from the Hotline.
In the event of a defect or problem with your LANDOLL equipment, please notify
