Windshield Wiper Blade Inserts To replace your windshield wiper blade inserts, lift the wiper arm away from the windshield. Pinch the two tabs on the wiper arm and slide the insert out of the blade. Slide the new one in place. Make sure the tabs are locked into position. 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). Lubrication Accelerator Control System Refer to the Maintenance Schedule to determine 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. When cleaning the engine compartment with water or steam, avoid directing the flow onto the throttle linkage in a manner that would cause moisture to enter the cables. Hood Latches and Hood Hinge Refer to the Maintenance Schedule to determine how to lubricate the hood latch and hood hinge assembly. 6-36
