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).
Caution
Exceeding the 80 km/h (50 mph)
maximum speed when a compact
spare assembly is installed can
damage the vehicle’s driveline
components.

VEHICLE CARE 343
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 with the spare tire
installed and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the
tread of the spare tire, have the
standard tire repaired or replaced as
soon as convenient and return the
spare tire to the storage area.
When using a compact spare tire, the
AWD (if equipped), ABS, and Traction
Control systems may engage until the
spare tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible wheel slip.Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact spare
can get caught on the rails which
can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires. They
will not fit. Keep the spare tire and its
wheel together.
Caution
Tire chains will not fit the compact
spare. Using them can damage the
vehicle and the chains. Do not use
tire chains on the compact spare.

Caution
Towing an all-wheel-drive vehicle
with all four wheels on the ground,
or even with only two of its wheels
on the ground, will damage
drivetrain components. Do not tow
an all-wheel-drive vehicle with any
of its wheels on the ground.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach angles,
if necessary. A towed vehicle should
have its drive wheels off the ground.
In the case the disabled vehicle must
be towed, contact Roadside Service if
the vehicle is covered by GM and/or
OnStar roadside benefits. Otherwise
contact a professional towing service.
If the vehicle is equipped with a tow
eye, it is located in the trunk next to
the spare tire tools. Only use the tow
eye to pull the vehicle onto a flatbed
car carrier from a flat road surface. Do
not use the tow eye to pull the vehicle
from snow, mud, or sand.
Caution
Improper use of the tow eye can
cause vehicle damage. Use caution
and low speeds to prevent damage
to the vehicle.
Front Attachment Point
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.
Install the tow eye into the socket and
turn it until it is fully tightened. When
the tow eye is removed, reinstall the
cover with the notch in the original
position.
