Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9‑10. The warning
light will remain on until the tire
pressure is corrected. During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early
indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑58.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when

Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.

page 13‑16 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System)
theft-deterrent system.
PASS-Key III+ is a passive
theft deterrent system. The system is automatically armed
when the key is removed from the
ignition.
You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it shuts down the
vehicle's starter and fuel systems.
The starter will not work and fuel will
stop being delivered to the engine.
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security message comes on, the
key may have a damaged
transponder. Turn the ignition off
and try again.If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
instrument panel PASS KEY fuse.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be faulty. See your
dealer or a locksmith who can
service the PASS-Key III+ to have a
new key made. See
Fuses and
Circuit Breakers on page 10‑43.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. This procedure is for
learning additional keys only. If all
the currently programmed keys are
lost or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

Notice:Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications on
page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required. To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, stop
and park the vehicle. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light is
still flashing, follow the previous
steps and see your dealer for
service as soon as possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required. The following may correct an
emission system malfunction:
.Check that the fuel cap is fully
installed. See
Filling the Tank on
page 9‑43. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.

Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. SeeTire Messages on
page 5‑40. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10‑57. When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See
Tire Pressure Monitor
Operation on page 10‑60.
Engine Oil Pressure Light
Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty. Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
goes off.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and it might
have some other system problem.

Black plate (30,1)GMC Savana Owner Manual - 2012 - 2nd - 11/11/11
5-30 Instruments and Controls
The trip odometer has a feature
called the retro-active reset. This
can be used to set the trip odometer
to the number of kilometers (miles)
driven since the ignition was last
turned on. This can be used if the
trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature,
press and hold
Vfor at least
four seconds. The trip odometer
will display the number of
kilometers (km) or miles (mi) driven
since the ignition was last turned on
and the vehicle was moving. Once
the vehicle begins moving, the trip
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 miles) before it is
started again, and then the
retro-active reset feature is
activated, the display will show
8 km (5 miles). As the vehicle begins
moving, the display will then
increase to 8.1 km (5.1 miles),
8.2 km (5.2 miles), etc. If the retro-active reset feature is
activated after the vehicle is started,
but before it begins moving, the
display will show the number of
kilometers (km) or miles (mi) that
were driven during the last ignition
cycle.
Fuel Range
Press3until FUEL RANGE
displays. This display shows the
approximate number of remaining
kilometers (km) or miles (mi) the
vehicle can be driven without
refueling. The display will show
LOW if the fuel level is low.
The fuel range estimate is based on
an average of the fuel economy
over recent driving history and the
amount of fuel remaining in the fuel
tank. This estimate will change if
driving conditions change. For
example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway, the
number may change even though
the same amount of fuel is in the fuel tank. This is because different
driving conditions produce different
fuel economies. Generally, freeway
driving produces better fuel
economy than city driving.
If the vehicle is low on fuel, the
FUEL LEVEL LOW message will be
displayed. See
“FUEL LEVEL LOW”
under Fuel System Messages on
page 5‑37 for more information.
Average Economy
Press
3until AVG ECONOMY
displays. This display shows the
approximate average liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number is
calculated based on the number of
L/100 km (mpg) recorded since the
last time this menu item was reset.
To reset AVG ECONOMY, press and
hold
V. The display will return
to zero.
