If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly.
If air goes
out of a tire, it’s much more likely to lepk out slowly.
But if you should ever have a “blowout,” here are a few\

tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
Then replace the pressure cap. Be sure the arrows on
the pressure
cap line up like this.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in
a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle
to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well
off the road if possible.
If your tire goes flat, the next section shows how to use
your jacking equipment to change a flat tire safely.

If your Buick has aluminum wheels, there are no wheel
covers that have to be removed.

A CAUTION:
Getting under a vehicle when it is jacked up is
dangerous.
If the vehicle slips off the jack, you
could be badly injured
or kill,ed. Never get under
a vehicle when it
is supported only by a jack.
Raise the vehicle by rotating the wheel wrench
clockwise. Raise the vehicle far enough
off the ground
so there is enough room for the spare tire to fit.
Remove all the wheel nuts and take
off the flat tire.

A CAUTION:
Rust or dirt on the wheel, or on the parts to
which it
is fastened, can make the wheel nuts
become loose after
a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle.
In an emergency, you can use a cloth or
a paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to get
all the rust or dirt off.
Remove any rust or dirt from the wheel bolts, mounting
surfaces or spare wheel.
