Single Belt Accessory Drive Your vehicle uses aserpentine belt that is lighter, more durable and more fuel efficient than systems with several belts. The belt runs over or around the pulleys on the engine. A tensioner is used to keep the belt tight at all times. The tensioner also makes replacing the belt easier. If you need to replace the belt, be sure to get the correct replacement belt. Your dealership or parts supplier can help you with this. The Accessory Drive Belt Routing label on your vehicle will show you how to r0ut.e the belt your vehicle uses. Air Conditioning Every now and then have your dealership check your air conditioning system to be sure it has not lost any cooling ability. If you think the system is not working properly, have your dealership check it out as soon as possible. The air conditioning will not work when the temperature is below 40" F (4" C). Accelerator Control System Your Maintenance Schedule will tell you how often the accelerator linkage pivot points must be lubricated and what type of lubricant to use. Accelerator cables and cruise control cables should not be lubricated. Any cables that are worn or are hard to pull should be replaced.
