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.

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).
You should let your dealer’s
service department
or other qualified service center do
these
jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a service manual. See Service Publications
Ordering lnformation
on page 7- 10.
Steering, Suspension and Front
Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose
or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See Engine Exhaust
on page
2-3 1.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
