fuel pressure PONTIAC G8 2008 User Guide

Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inate
them to the proper pressure. Driving
on a signicantly under-inated
tire causes the tire to overheat and
can lead to tire failure.
Under-ination also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-ination
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltalewill ash for approximately
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires
or wheels on the vehicle that prevent
the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue
to function properly.

At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and

to keep the engine oil at the
proper level can cause damage to
the engine not covered by the
vehicle warranty.
Check the engine oil level and add
the proper oil if necessary. See
Engine Oil on page 9-8.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 9-13.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer
uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect the vehicle’s tires and make
sure they are inated to the correct
pressures. Do not forget to check the
spare tire. SeeInflation - Tire
Pressure on page 9-46. Check to
make sure the spare tire is stored
securely. SeeChanging a Flat Tire
(V6 Engine) on page 9-71.
Tire Wear Inspection
Tire rotation may be required for
high mileage highway drivers prior to
the Engine Oil Life System service
notication. Check the tires for
