400 Vehicle Care
Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
{Warning
If the vehicle has 235/
55R20h size tires, do not
use tire chains. There is not
enough clearance. Tire
chains used on a vehicle
without the proper amount(Continued)
Warning (Continued)
of clearance can cause
damage to the brakes,
suspension, or other vehicle
parts. The area damaged by
the tire chains could cause
loss of control and a crash.
Use another type of traction
device only if its
manufacturer recommends
it for the vehicle's tire size
combination and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if
it contacts the vehicle. Do
not spin the wheels. If
traction devices are used,
install them on the front
tires.
Caution
If the vehicle is equipped
with a tire size other than
235/55R20, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the front axle. Do not use
chains on the tires of the
rear axle. Tighten them as
tightly as possible with the
ends securely fastened.
Drive slowly and follow the
chain manufacturer's
instructions. If the chains
contact the 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 the vehicle.

you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time
could result in loss of
braking and handling. This
could lead to a crash and
you or others could be
injured. Use only one
compact spare tire at a time.
If this vehicle has a compact
spare tire, it was fully inflated
when new; however, it can
lose air over time. Check the
inflation pressure regularly.
It should be 420 kPa (60 psi).
Stop as soon as possible and
check that the spare tire is
correctly inflated after being
installed on the vehicle. The
compact spare tire is designed
for temporary use only. The
vehicle will perform differently

Satisfaction
Procedure
Your satisfaction and goodwill
are important to your dealer
and to Cadillac. Normally, any
concerns with the sales
transaction or the operation
of the vehicle will be resolved
by your dealer's sales or
service departments.
Sometimes, however, despite
the best intentions of all
concerned, misunderstandings
can occur. If your concern has
not been resolved to your
satisfaction, the following
steps should be taken:
STEP ONE : Discuss your
concern with a member of
dealership management.
Normally, concerns can be
quickly resolved at that level.
If the matter has already been
reviewed with the sales,
