2009 GMC SAVANA ignition

Speedometer and Odometer
The speedometer shows the vehicle speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
This vehicle has a tamper resistant odometer.
The digital odometer will read 999,999 if it is
turned back.
If the vehicle needs a new odometer installed, it
must be set to the mileage total of the old odometer.
If that is not possible, then it must be set at zero and
a label must be put on the driver door to show the
old mileage reading when the new odometer was
installed.
Trip Odometer
The trip odometer can show how far the vehicle
has been driven since the trip odometer was last set
to zero.
Press the Trip/Fuel button on the Driver Information
Center (DIC) switch to display the trip odometer and the
regular odometer information.
SeeDIC Operation and Displays on page 3-43for more
information on resetting the trip odometer.
To display the odometer reading with the ignition off,
press the Trip/Fuel button on the Driver Information
Center switch.

{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-27
for more information, including important safety
information.
Charging System Light
This light comes on briefly
when the ignition key is
turned to START, 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.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message in
the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-50for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light on,
turn off accessories, such as the radio and air
conditioner.

Voltmeter Gage
When the engine is not
running, but the ignition is
on, this gage shows the
battery’s state of charge
in DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
The vehicle can be only driven for a short time with the
reading in either warning zone. If it must be driven,
turn off all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking,
both need to work.
If the warning light comes on, there could be a brake
problem. Have the brake system inspected right away.
This light should come on briefly when ignition key is
turned to ON/RUN. If it does not come on, have it fixed
so it will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. See
Parking Brake on page 2-26for more information. The
light stays on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push, or the
pedal might go closer to the floor. It could take longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-24.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United StatesCanada

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-33.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-50for all brake
related DIC messages.
StabiliTrak®Indicator Light
For vehicles with the
StabiliTrak®system, this
light comes on or flashes,
according to the description
table for the StabiliTrak
system.
For more information, seeStabiliTrak
®System on
page 4-6.
Three chimes sound if the light turns on and one chime
if the light turns off.
If this light remains on steady, the vehicle needs to be
taken in for service.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. It also
provides an indicator of how hard the vehicle is working.
During a majority of the operation, the gage will read
210°F (100°C) or less. If the vehicle is pulling a load or
going up hills, it is normal for the temperature to fluctuate
and approach the 250°F (122°C) mark. If the gage
reaches the 260°F (125°C) mark, it indicates that the
cooling system is working beyond its capacity.
SeeEngine Overheating on page 5-31.
Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briefly when the engine is
started. If it does not, have
the vehicle serviced by
your dealer/retailer.
If the system is working normally the indicator light then
goes off.
This light also comes on when one or more of the tires
is significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC) can accompany the light. SeeDIC
Warnings and Messages on page 3-50for more
information.
Stop and check the tires as soon as it is safe to do so.
If underinflated, inflate the tire to the proper pressure.
SeeTires on page 5-54for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light flashes for approximately 60 seconds
and then stays on for the remainder of the ignition
cycle. SeeTire Pressure Monitor System on page 5-64
for more information. United States

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 should come on
when the ignition is on, but
the engine is not running,
as a check to show it
working. If it does not, have
the vehicle serviced by your
dealer/retailer.If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before any
problem is apparent. Being aware of the light can prevent
more serious damage to the vehicle. This system assists
the service technician in correctly diagnosing any
malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle’s fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by the vehicle warranty.
3-36

Fuel Gage
The fuel gage, when the ignition is on, indicates how
much fuel is left in the vehicle’s fuel tank.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
The gage first indicates empty before the vehicle is out
of fuel, and the fuel tank should be refueled soon.Listed are four situations customers might experience
with the fuel gage. None of these indicate a problem with
the fuel gage:
•At the gas station, the fuel pump shuts off before
the gage reads full.
•It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank’s
capacity to fill the tank.
•The gage moves a little while turning a corner or
speeding up.
•The gage does not go back to empty when the
ignition is turned off.
If the vehicle has the DURAMAX Diesel engine, see the
DURAMAX Diesel manual for more information. United StatesCanada
