To take off the cap, turn it slowly to the left
(counterclockwise).
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside
of Your Pontiac” in the Index.
When you put the cap back on, turn it to the right until
you hear at least three clicks.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you. If you get
the wrong type, it may not fit and your fuel tank
and emissions system might be damaged.

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.
