Before closing the hood, be sure all the filler caps are
on.
Then just pull the hood down and close it firmly.
Engine Oil
LOW
OIL
If the LOW OIL light on the instrument panel comes on,
it means you need to check your engine oil level right away. For more information, see
LOW OIL in the Index.
You should check your engine oil level regularly; this is
an added reminder.
It’s a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.

Inflation - Tire Pressure
The Tire-Loading Information label which is on 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.
If you’ll be driving at speeds higher than 100 mph (160 km/h)
where it is legal, raise the “cold” inflation pressure of\
each
tire to 35 psi (240 k Pa). When you end this very high speed
driving, reduce the “cold” inflation pressures to those
listed
on the tire loading information label.
Don’t let anyone tell you that underinnation 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
0 Bad handling
Bad fuel economy.
(Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get:
Unusual wear
Bad handling
Rough ride
0 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 ou,t dirt and
moisture.

Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer's body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust contr~l
can collect on the underbody.
If these are not removed,
accelerated corrosion (rust) can occur on the underbody
parts such
as fuel lines, frame, floor pan, and exhaust
system even though they have corrosion protection.
At least every speng, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect.
Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system
can do this for you.
e.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall uppn
and
attack painted surfaces on your vehicle. This damage
can take two
foims: blotchy, ringlet-shaped ,'
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this, Pantiac
will repair, at no charge to the owner, the surfaces bf
new vehicles damaged by
this fallout conditiop.within
