Stowing a tire with the valve stem
pointed down could result in
damage to the wheel.
Caution
The tire hoist is designed to be
raised and lowered with tension on
the cable. If the hoist must be
raised or lowered without a tire
attached, do so only by hand, and
at a slow pace, to avoid damaging
the mechanism. Do not use power
tools.

could come loose and cause a crash.
To avoid personal injury or property
damage, always store the spare tire
when the vehicle is parked on a
level surface.
If the vehicle has 275/60R20 or 275/
50R22 size tires, the flat tire must be
stored inside of the vehicle using the
flat tire secure strap inside the glove
box. See “Storing a Flat Tire Inside of
the Vehicle ”later in this section.
If the vehicle has 265/65R18 or 275/

Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure0400 and
Vehicle Load Limits 0240 for
information regarding proper tire
inflation and loading the vehicle. For instructions on how to remove, install,
or store a spare tire, see
Tire Changing
0 413.
If equipped with a temporary use
full-size spare tire, it is indicated on
the tire sidewall. See Tire Sidewall
Labeling 0395. This spare tire should
not be driven on over 112 km/h
(70 mph), or 88 km/h (55 mph) when
pulling a trailer, at the proper
inflation pressure. Repair and replace
the road tire as soon as it is
convenient, and stow the spare tire for
future use.
Caution
If the vehicle has four-wheel drive
and a different size spare tire is
installed, do not drive in four-wheel
drive until the flat tire is repaired
and/or replaced. The vehicle could
be damaged and the repairs would
not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed
on the vehicle.

440 VEHICLE CARE
Floor Mats
{Warning
If a floor mat is the wrong size or is
not properly installed, it can
interfere with the pedals.
Interference with the pedals can
cause unintended acceleration and/
or increased stopping distance
which can cause a crash and injury.
Make sure the floor mat does not
interfere with the pedals.
Use the following guidelines for
proper floor mat usage:
.The original equipment floor mats
were designed for your vehicle.
If the floor mats need replacing, it
is recommended that GM certified
floor mats be purchased. Non-GM
floor mats may not fit properly and
may interfere with the pedals.
Always check that the floor mats do
not interfere with the pedals.
.Do not use a floor mat if the vehicle
is not equipped with a floor mat
retainer on the driver side floor.
.Use the floor mat with the correct
side up. Do not turn it over.
.Do not place anything on top of the
driver side floor mat.
.Use only a single floor mat on the
driver side.
.Do not place one floor mat on top
of another.
Removing and Replacing the
Floor Mats
Pull up on the rear of the floor mat to
unlock each retainer and remove.
Reinstall by lining up the floor mat
retainer openings over the carpet
retainers and snapping into position. Make sure the floor mat is properly
secured in place.
Verify the floor mat does not interfere
with the pedals.
Cleaning Rubber Floor Mats
(All-Weather Mats and Floor
Liners)
{Warning
Do not use cleaners that contain
silicone, wax-based products,
or cleaners that increase gloss on
rubber floor mats/liners. These
cleaners can permanently change
the appearance and feel of the
rubber and can make the floor
mats/liners slippery. Your foot
could slip while operating the
vehicle, and you could lose control,
resulting in a crash. You or others
could be injured.
Use a soft cloth and/or a brush
dampened with water to remove dust
and loose dirt. For more thorough
cleaning, use a mild soap solution.

Customer 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, service or parts manager,
contact the owner of your dealership
or the general manager.
STEP TWO : If after contacting a
member of dealership management, it
appears your concern cannot be
resolved by your dealership without
