NOTICE:
If your Pontiac has P195/70R14,
P195/65R15 or P205/60R15 size
tires, don't use tire chains; they can
damage your vehicle. If you have
other 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 with chains on will
damage your vehicle.

instructions. And always open your
doors or windows when you're cleaning
