{Warning
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size, load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
See
Tire Pressure Monitor
System 0334.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See Vehicle Load Limits
0 191.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be
affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.

Fabric/Carpet/Suede
Start by vacuuming the surface
using a soft brush attachment. If a
rotating vacuum brush attachment is
being used, only use it on the floor
carpet. Before cleaning, gently
remove as much of the soil as
possible:
.Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
. For solid soils, remove as much
as possible prior to vacuuming.
To clean: 1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is
recommended to prevent lint
transfer to the fabric or carpet.
2. Remove excess moisture by gently wringing until water does
not drip from the cleaning cloth.
3. Start on the outside edge of the soil and gently rub toward the
center. Fold the cleaning cloth to a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by plain
water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
After cleaning, use a paper towel to
blot excess moisture.
Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
Use a microfiber cloth on high gloss
surfaces or vehicle displays. First,
use a soft bristle brush to remove
dirt that can scratch the surface.
Then gently clean by rubbing with a
microfiber cloth. Never use window
cleaners or solvents. Periodically
hand wash the microfiber cloth
separately, using mild soap. Do not
use bleach or fabric softener. Rinse
thoroughly and air dry before
next use.
Caution
Do not attach a device with a
suction cup to the display. This
may cause damage and would
not be covered by the vehicle
warranty.
