1994 GMC SIERRA flat tire

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 a tire goes flat, the next section shows how to use your jac\
king equipment
to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place. Turn
on your hazard warning flashers.

Changing the Tire
Start with the jack, the
jack handle and the
ratchet.
If the flat tire is on the rear of the vehicle, you'll need the jack handle
extensions
also.
I
Attach the jack handle
(and jack handle
extensions,
if needed)
to the jack.
With the
UP marking
on the ratchet facing
you, rotate the ratchet
to
the right.

That will lift the jack head a little. Before raising the vehicle, do the
following things.
Put your spare tire near the flat tire.
Remove the wheel trim.
Be careful; the rim edges may be sharp. Don't
try to remove it with your
bare hands.
- If your vehicle has
wheel nut caps, use
the wheel wrench and
ratchet, with
DOWN
facing you, to unscrew
and take them off.
Then take the hub cap off.
If the wheel has a trim ring, remove it by using the flat end of the wheel
wrench.

NOTICE:
Raising your vehicle with the jack improperly positioned will
damage the vehicle or may allow the vehicle to fall
off the jack.
Be sure to fit the jack lift head into the proper location before
raising your vehicle.
Front Position
I
Raise the vehicle by rotating the ratchet to the right. Make sure the UP
marking faces you. Use the jack handle extentions if the flat is on the rear of
the vehicle. 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.

Malfunction Indicator
(SERVICE ENGINE SOON) Lamp
The Malfunction Indicator (SERVICE ENGINE SOON) Lamp on your
instrument panel lets you know when
your emission system needs service.
The light
will come on briefly when you start your engine to let you know
that the system is working. If
it does not come on when you start your
engine,
or if it comes on and stays on while you’re driving, your system
may need service. Your vehicle should still be driveable, but
you should
have your system serviced right away.
Secondary Air hjection Reaction (AIR) System
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE SOON) Lamp on your instrument panel will come on.

The Certification/Tire
label is found on the
rear edge of the
driver’s door or
in the
Incomplete Vehicle
Document
in the cab.
The label shows
the size of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The Certification/Tire label also tells
you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR). To find out
the actual loads on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help you
with this. Be sure
to spread out your load equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle, or
the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.

Tires
We don’t make tires. Your new vehicle comes with high quality tires made
by a leading tire manufacturer. These tires
are warranted by the tire
manufacturers and their warranties are delivered with
every new vehicle. If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each of these manufacturers.
Inflation - Tire Pressure
The Certificatioflire label which is on the rear edge of the driver’s door, or
on the incomplete vehicle document in the cab, 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.
You can operate some vehicles at reduced inflation pressures only when
you’ll be carrying reduced loads. On those vehicles, the minimum cold
inflation pressures for a typical reduced load are printed on the “Improved
Ride Tire Pressure’’ label located on the driver’s door. Weigh the vehicle to
