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).
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer
to the Maintenance Schedule to determine how often to lubricate them
and what type
of 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.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
0 Engine misfiring
Loss of performance
Exhaust system components hanging lower than normal.
Loud exhaust system noises.
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you
use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

Downloaded from www.Manualslib.com manuals search engine lnflation - Tire Pressure
The CertificatiodTire label which is on the rear edge of the driver’s door,
shows the correct inflation pressures for your tires, when they’re cold.
“Cold” means your vehicle has been sitting for at least three hours or driven
no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not. If your tires don’t have enough air
(underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires
have valve caps, be sure to put them back on. They help prevent
leaks by keeping
out dirt and moisture.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system in your vehicle needs refrigerant, be sure
the proper refrigerant is
used. If you’re not
sure, ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet.
Refrigerant should be added only by a qualified
A/C technician.
