Windshield Wiper Blade lnserfs
J
PO232
To replace the windshield wiper blade insert, lift the wiper arm and rotate the
blade until
it is facing away from the windshield. Unlatch the end of the insert
from the holding clips. Remove the insert and slide a new one in place,
Make sure the blade
is secured in the clips.
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).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lubrication
Accelerator Control System
Your maintenance schedule will tell you how often the accelerator linkage
pivot points must be lubricated. See “Recommended Fluids and Lubric\
ants”
in
the Index for the proper lubricant to use.
Accelerator cables and cruise control cables should not be lubr\
icated. Any
cables that are worn or are hard to pull
should be replaced.
