Pontiac 2005 Vibe - Manual (Page 288)

You need to stop as soon as possible and check your
tires for damage. If a tire is flat, see If a Tire Goes
Flat on page 5-74 and Changing a Flat Tire on
page 5-75. Also check the tire pressure in all four tires,
and set them to the specified level shown on the tire
and loading label. See Inflation - Tire Pressure on
page 5-64 for additional information.
Note: The tire pressure monitoring system on
your vehicle will warn you when one of your tires
is significantly under-inflated and when some
combinations of your tires are significantly
under-inflated. However, there are other combinations
of significantly under-inflated tires for which your
tire pressure monitoring system may not warn you.
These other combinations are relatively common,
accounting for approximately half the instances in
which vehicles have significantly under-inflated tires.
For example, your system may not warn you when both
tires on the same side or on the same axle of your
vehicle are significantly under-inflated. It is particularly
important, therefore, for you to check the tire pressure in
all of your tires regularly and maintain proper pressure.
In order for the tire pressure monitoring system to
work properly you will need to reset (initialize) the tire
pressure monitoring system. Any time you check and/or
adjust a tire’s pressure, repair or replace a tire or
wheel or rotate the tires the tire pressure monitor system
needs to be reset.
Do not reset (initialize) the system without first correcting
the cause of the low-tire condition. If the system is
reset when the tire pressures are incorrect, the system
will not function properly and may not alert you when
a tire is low.
To reset (initialize) the system:
1. Park the vehicle at a safe place and apply the
parking brake. Turn the engine off.
2. Turn the ignition to ON with the engine off.
3. If the low-tire pressure
warning light is on,
push the SET (reset)
button for a few
seconds. The low-tire
warning light should go
off. The reset button
is on the instrument
panel to the left of the
steering wheel.
