Buick 2009 Enclave - Manual (Page 155)

Tire Pressure Light
If the vehicle has a tire pressure
monitoring system, the tire pressure
light provides information about tire
pressures and the Tire Pressure
Monitoring System. The light should
come on briefly as the engine is
started. If it does not, have the
vehicle serviced by your dealer/
retailer.
When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. See DIC
Warnings and Messages on
page 3-50 for more information.
Stop and check the tires as soon
as it is safe to do so. If underinflated,
inflate to the proper pressure.
See Tires on page 5-37 for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there could be
a problem with the Tire Pressure
Monitor System. The light flashes for
about a minute and stays on steady
for the remainder of the ignition
cycle. This sequence repeats with
every ignition cycle. See Tire
Pressure Monitor System on
page 5-44 for more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer/
retailer.
