Buick ENCLAVE - 2009 Owner's Manual page 311

A vehicle specific Tire and
Loading Information label is
attached to your vehicle.
This label shows your vehicle's
original equipment tires and
the correct inflation pressures for
your tires when they are cold.
The recommended cold tire
inflation pressure, shown on the
label, is the minimum amount
of air pressure needed to
support your vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight your
vehicle can carry, and an
example of the Tire and Loading
Information label, see Loading
the Vehicle on page 4-16. How
you load your vehicle affects
vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.
When to Check
Check your tires once a month or
more. Do not forget to check the
compact spare tire, if the vehicle
has one. It should be at 60 psi
(420 kPa). For additional
information regarding the
compact spare tire, see Compact
Spare Tire on page 5-83.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inflated simply by
looking at them. Radial tires may
look properly inflated even
when they are under-inflated.
Check the tire's inflation
pressure when the tires are
cold. Cold means your vehicle
has been sitting for at least
three hours or driven no more
than 1 mile (1.6 km).
Service and Appearance Care
Remove the valve cap from the
tire valve stem. Press the
tire gage firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is
low, add air until you reach the
recommended amount.
If you overfill the tire, release air
by pushing on the metal stem in
the center of the tire valve.
Re-check the tire pressure with
the tire gage.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.
