How to Check
Use a good quality pocket-type
gauge to check tyre pressure.
Proper tyre inflation cannot be
determined by looking at the tyre.
Check the tyre inflation pressure
when the tyres are cold, meaning
the vehicle has not been driven for
at least three hours or no more
than 1.6 km (1 mi).
Remove the valve cap from the
tyre valve stem. Press the tyre
gauge firmly onto the valve to get
a pressure measurement. If the
cold tyre inflation pressure
matches the recommended
pressure on the Tyre and Loading
Information label, no further
adjustment is necessary. If the
inflation pressure is low, add air
until the recommended pressure is
reached. If the inflation pressure
is high, press on the metal stem in
the centre of the tyre valve to
release air.
Recheck the tyre pressure with the
tyre gauge.
Refit the valve caps on the valve
stems to keep out dirt and
moisture. Use only valve caps
designed for the vehicle by GM.
TPMS sensors could be damaged
and would not be covered by the
vehicle warranty.
Tyre Pressure for
High-Speed Operation
{
Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tyres. Sustained
high-speed driving causes excessive
heat build-up and can cause sudden
tyre failure. This could cause a
crash, and you or others could be
killed. Some high-speed rated tyres
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle to

Warning (Continued)
be driven at high speeds, make sure
the tyres are rated for high-speed
operation, are in excellent
condition, and are set to the correct
cold tyre inflation pressure for the
vehicle load.
Vehicles with tyre sizes listed in the
High Speed Operation Inflation
Pressures table require inflation
pressure adjustment when driving the
vehicle at speeds of 160 km/h
(100 mph) or higher. Set the cold tyre
inflation pressure to the
corresponding value in the table for
the tyre size on the vehicle.
