warning GMC SAVANA PASSENGER 2009 Owner's Manual

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.
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 3-31.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-48for all brake
related DIC messages.

Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes on
briefly when the engine
is started.
It provides information about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that 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 3-48for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinflated, inflate to the
proper pressure. SeeTires on page 5-55for 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. SeeTire Pressure Monitor System
on page 5-65for 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 should come 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.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located at
the bottom of the instrument panel cluster. The DIC
buttons are located on the instrument panel, next to the
instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected.
If your vehicle has these features, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. The compass
direction appears on the top right corner of the DIC
display. The outside air temperature automatically
appears in the bottom right corner of the DIC display.
If there is a problem with the system that controls
the temperature display, the numbers will be replaced
with dashes. If this occurs, have the vehicle serviced by
your dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 3-57for
more information.
DIC Operation and Displays
The DIC has different displays which can be accessed
by pressing the DIC buttons located on the instrument
panel, next to the instrument panel cluster.
DIC Buttons
The buttons are the
trip/fuel, vehicle
information, customization,
and set/reset buttons.
The button functions are
detailed in the following
pages.
3(Trip/Fuel):Press this button to display the
odometer, trip odometers, fuel range, average economy,
fuel used, timer, average speed, and digital tachometer.
3-41

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 miles (mi) or kilometers (km) that
were driven during the last ignition cycle.
Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining miles (mi) or kilometers (km) 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
vehicle’s 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 your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL LOW”
underDIC Warnings and Messages on page 3-48
for more information.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of mpg
(L/100 km) recorded since the last time this menu item
was reset. To reset AVG ECONOMY, press and hold the
set/reset button. The display will return to zero.
Fuel Used
Press the trip/fuel button until FUEL USED displays.
This display shows the number of gallons (gal) or
liters (L) of fuel used since the last reset of this menu
item. To reset the fuel used information, press and hold
the set/reset button while FUEL USED is displayed.
Timer
Press the trip/fuel button until TIMER displays.
This display can be used as a timer.
To start the timer, press the set/reset button while TIMER
is displayed. The display will show the amount of time
that has passed since the timer was last reset, not
including time the ignition is off. Time will continue to be
counted as long as the ignition is on, even if another
display is being shown on the DIC. The timer will record
up to 99 hours, 59 minutes and 59 seconds (99:59:59)
after which the display will return to zero.

To stop the timer, press the set/reset button briefly while
TIMER is displayed.
To reset the timer to zero, press and hold the set/reset
button while TIMER is displayed.
Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display shows the average speed
of the vehicle in miles per hour (mph) or kilometers
per hour (km/h). This average is calculated based on the
various vehicle speeds recorded since the last reset of
this value. To reset the value, press and hold the
set/reset button. The display will return to zero.
Digital Tachometer
Press the trip/fuel button until Tachometer ##00 RPM
displays. This display shows the engine speed in
