282 VEHICLE CARE

Run-Flat Tyres

This vehicle, when new, may have had
run-flat tyres. There is no spare tyre,
no tyre changing equipment and no
place to store a tyre in the vehicle.
The vehicle also has a Tyre Pressure
Monitor System (TPMS) that indicates
a loss of tyre pressure in any of the
tyres.
Warning
If the low tyre warning light
displays on the instrument cluster,
the handling capabilities will be
reduced during severe manoeuvres.
Driving too fast could cause loss of
control and you or others could be
injured. Do not drive over 90 km/h
(55 mph) when the low tyre
warning light is displayed. Drive
cautiously and check the tyre
pressures as soon as possible.
Run-flat tyres can be driven on with
no air pressure. There is no need to
stop on the side of the road to change
the tyre. Continue driving; however,
do not drive too far or too fast.
Driving on the tyre may not be
possible if there is permanent damage.
To prevent permanent damage, keep
speed below 80 km/h (50 mph). With
a light load the vehicle can be driven
up to 100 km (60 mi); with a
moderate load 80 km (50 mi); and a
heavy load 45 km (25 mi). As soon as
possible, contact the nearest
authorised GM or run-flat servicing
facility for inspection and repair or
replacement.
When driving on a deflated run-flat
tyre, avoid potholes and other road
hazards that could damage the tyre
and/or wheel beyond repair. When a
tyre has been damaged, or driven any
distance while deflated, check with an
authorised run-flat tyre service centre
to determine whether the tyre can be
repaired or should be replaced. To
maintain the run-flat feature, all
replacement tyres must be run-flat
tyres.
To locate the nearest GM or run-flat
servicing facility, call Customer
Assistance.
The valve stems on run-flat tyres have
sensors that are part of the TPMS. See
Tyre Pressure Monitor System 0 285.
These sensors contain batteries that
are designed to last for 10 years under
normal driving conditions. See your
dealer for wheel or sensor
replacement.
Caution
Using liquid sealants can damage
the tyre valves and tyre pressure
monitor sensors in the run-flat
tyres. This damage is not covered
by the vehicle warranty. Do not use
liquid sealants in run-flat tyres.

Low-Profile Tyres

If the vehicle has 265/35ZR19 or
295/30ZR19 size tyres, they are
classified as low-profile tyres.
