Windshield Wiper Blade Inserts
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
possi bleb
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 surface 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.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s maintenance schedule will tell you how often to lubricate them.
See “Recommended Fluids and Lubricants” in the Index for
the proper
lubricant to use.
You should
not use penetrating oils because they could wash out the factory
installed lubricant and cause
the lock to bind. De-icers which contain
alcohol could also
wash away the lubricant, so be sure to lubricate the lock
after using
a de-icer of this type.

1 600 and 10 000 km) of driving. For proper torque, see “Wheel Nut
Torque” in the Index.
Used Replacement Wheels
A CAUTION:
Putting a used wheel on your vehicle is dangerous. You can’t
know
how it’s been used or how many miles it’s been driven. It
could fail suddenly and cause an accident. If you have to replace
a wheel use a new GM original equipment wheel.

use tire chains; they can damage your vehicle.
If you don’t have dual wheels or if you have a tire size other

when you must. Use chains that are the proper size for your
tires. Install them on the tires of the rear axle.

Tighten them
as tightly as possible with the ends securely

stop and retighten them. If the contact continues, slow down
until it stops. Driving too fast
or spinning the wheels with chains
on
will damage your vehicle.
