To replace your wiper blade inserts, pinch the
two
tabs on the wiper arm and
slide the insert out of the blade. When you slide the new one into place, be
sure the tabs are locked in 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.
