428 MAINTAINING YOUR VEHICLE Severe Usage is defined as: • Police, taxi, limousine, commercial type operation, or trailer towing where the vehicle is driven regularly for more than 45 minutes of continuous operation. NOTE: Refer to Section 8 of this manual for Maintenance Schedules. If the transmission is disassembled for any reason, the fluid and filter should be changed. Special Additives Do not add any fluid additives to the transmission. The only exception to this policy is the use of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided as they may adversely affect seals. Front And Rear Wheel Bearings Front and rear wheel bearings are permanently sealed. No regular maintenance is required for these components. Appearance Care and Protection from Corrosion Protection of Body and Paint from Corrosion Vehicle body care requirements vary according to geographic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. Outside parking, which exposes your vehicle to airborne contaminants, road surfaces on which the vehicle is operated, extreme hot or cold weather and other extreme conditions will have an adverse effect on paint, metal trim, and underbody protection.
