D Installation of electronic devices such as a mobile two−way radio, cassette tape player or CD player. D Repairs on or near the seat belt retractor assemblies. D Modification of the suspension system. D Modification of the front end structure. D Attachment of a grille guard (bull bar, kangaroo bar, etc.), snowplow, winches or any other equipment to the front end. D Repairs made on or near the front fenders, front end structure or console. CAUTION Do not modify, remove, strike or open the seat belt pretensioner assemblies, airbag sensor or surrounding area or wiring.
