Downloaded from www.Manualslib.com manuals search engine Door weatherstrips and rubber hood bumpers should be wiped clean with a
wet cloth and lightly coated with a rubber lubricant.
Never use too much of any lubricant and be sure
to wipe up any extra
lubricant when you are finished.
Some parts
that need lubricating are hard to get at. Window regulators and
controls are inside the doors. You can get to these by removing
the trim
panels.
Refer to the Maintenance Schedule to determine how often to lubricate
these items and what type
of lubricant to use.
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:
Engine misfiring
Loss of performance
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 Inflation - Tire Pressure
The Certificatioflire 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:
0 Too much flexing
Too much heat
Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation), you can get:
@ Unusual wear
0 Bad handling
6 Rough ride
6 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 underinflate\
d.
If your tires have valve caps, be sure to put them back
on. They help prevent
leaks by keeping out dirt and moisture.
