If using winter tires:
.
Use tires of the same brand
and tread type on all four
wheel positions.
.
Use only radial ply tires of
the same size, load range,
and speed rating as the
original equipment tires.
Winter tires with the same
speed rating as the original
equipment tires may not be
available for H, V, W, Y, and ZR
speed rated tires. If winter
tires with a lower speed rating
are chosen, never exceed the
tire's maximum speed
capability.
Run-Flat Tires
This vehicle, when new, may
have had run-flat tires. There
is no spare tire, no tire
changing equipment, and no
place to store a tire in the
vehicle.

Warning
While driving with run-flat
tires at a reduced inflation
pressure, avoid making
sudden stops or severe
maneuvers as the handling
capabilities of the tires will
be reduced. Driving too fast
could cause loss of control
and you or others could be
injured. Do not drive over
80 km/h (50 mph) with the
tire operating at low
pressure. Drive cautiously
and check the tire pressure
as soon as possible.
Run-flat tires can be driven up
to 80 km (50 mi) at speeds
less than 80 km/h (50 mph)
after a loss of inflation
pressure has occurred. There
is no need to stop on the side
of the road to change the tire.
The possible driving range
after a pressure loss will vary
based on the vehicle load and
driving conditions. As soon as
possible, contact the nearest
authorized GM or run-flat
servicing facility for inspection
and repair or replacement.
When driving on a deflated
run-flat tire, avoid potholes
and other road hazards that
could damage the tire and/or
wheel beyond repair. When a
tire has been damaged, or if
driven any distance while
deflated, check with an
authorized run-flat tire service
center to determine whether
the tire can be repaired or
should be replaced. To
maintain the run-flat feature,
all replacement tires must be
run-flat tires.
To locate the nearest GM or
run-flat servicing facility, call
Customer Assistance.
Self-Sealing Tires
This vehicle may have
self-sealing tires. These tires
have a material inside that can
seal punctures from common
road hazards, such as nails
