ECU PONTIAC GRAND PRIX 2003 Owner's Guide

Tire Chains
If your vehicle is an SE model with P225/60R16
size tires, don’t use tire chains, there’s not
enough clearance.
Tire chains used on a vehicle without the proper amount of clearance can cause damage
to the brakes, suspension or other vehicle
parts. The area damaged by the tire chains
could cause you to lose control of your vehicle
and you or others may be injured in a crash.
Use another type of traction device only if
its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions.
Follow that manufacturer’s
CAUTION: (Continued) instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if
it’s contacting your vehicle, and don’t
spin your wheels.
If you do find traction devices that will fit,
install them on the front tires.
Notice; If your vehicle is a GT model, a GTP model,
or if you have an
SE model without P225/60R16
size tires, use tire chains only where legal and only
when you must. Use only SAE Class
”S” type
chains that are the proper size for your tires. Install
them on the front tires and tighten them as tightly as possible with the ends securely fastened.
Drive slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them.
If the contact
continues, slow down
until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.

10. Don’t try to put the wheel cover on your compact
spare tire. It won’t fit. Store the wheel cover in the
trunk until you have the flat tire repaired or
replaced.
Notice: Wheei covers won’t fit on your compact
spare.
If you try to put a wheel cover on your
compact spare, you could damage the cover or
the spare.
Storing the Flat Tire and Tools
Storing a jack, a tire, or other equipment in the
passenger compartment
of the vehicle could
cause injury.
In a sudden stop or collision,
loose equipment could strike someone.
Store all these
in the proper place.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in the trunk. Use the
following procedure to secure the flat tire in the trunk. When
storing a full-size tire, you must use the extension
to help avoid wheel surface damage. Use the extension
and protector/guide located in the foam holder.
To store a
full-size tire, place the tire in the trunk valve stem facing
down, with the protector/guide placed through a wheel
bolt hole. Remove the protector and attach the retainer
securely. When putting the compact spare back in the
trunk, place the protector/guide back
in the foam holder.
Store the cover as far forward as possible.
