2005 CHEVROLET VENTURE ignition

Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery, in case you accidentally leave the
interior lamps on. If you leave any interior lamps on
while the ignition is in LOCK or OFF, they will
automatically turn off after 10 minutes. The lamps will
not come back on again until you do one of the
following:
Turn the ignition to RUN or ACCESSORY.
Turn the interior lamps thumbwheel all the way to
the right, then slightly back to the left.
Open a closed door, or close and reopen a door.
If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.
Switchbanks
There are two sets of switchbanks located in the front of
the vehicle. The switches will vary with the options
that are on your vehicle.
Instrument Panel Switchbank
The instrument panel switchbank is located in the
instrument panel below the comfort controls. This
switchbank may include the following:
Rear Fan Knob. SeeRear Climate Control System
(Without Entertainment System) on page 3-27or
Rear Climate Control System (With Entertainment
System) on page 3-29.
Rear Window Washer/Wiper. See “Rear Window
Washer/Wiper” underWindshield Washer on
page 3-9.
Traction Control Switches. SeeTraction Control
System (TCS) on page 4-8.
If your vehicle does not have some of these options,
there will be a blank.
If your vehicle is not equipped with the rear climate
control system, there will be a storage space in
this switchbank. The rubber mat can be removed for
cleaning. Snap the mat into place after cleaning.
3-19

Each of the two trip odometers can be used to keep track
of different trip distances, such as the mileage of a long
trip and the mileage driven on the current tank of fuel.
The trip odometers will continue to keep track of miles
(kilometers) driven even if they are not currently
displayed. To reset the odometer to zero, press and hold
the trip/reset button for at least 1.5 seconds, but less than
three seconds. Only the trip odometer that is showing in
the display will be reset.
Retro-Active Reset
Each of the two trip odometers has a feature called
retro-active reset. This feature can be used to set either
or both trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip
odometer at the beginning of a trip. To use the
retro-active reset feature, press and hold the trip/reset
button for at least three seconds.The trip odometer will then display the number of miles
(kilometers) driven since the ignition was last turned
on and you began driving. If you use the retro-active
reset feature after you have started the vehicle,
but before you begin moving, the display will show the
number of miles (kilometers) you drove during the
last ignition cycle. Once you begin driving, the trip
odometer will accumulate mileage. For example, if you
have driven 5.0 miles (8.0 km) since you started
your vehicle, and then activate the retro-active reset
feature, the display will show 5.0 miles (8.0 km). As you
drive, the display will then increase to 5.1 miles
(8.2 km), 5.2 miles (8.4 km), etc. Only the trip odometer
that is displayed will be affected by the retro-active
reset so that both trip odometers can be used
separately.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the airbag sensor, the airbag
modules, the wiring and the diagnostic module. For
more information on the airbag system, seeAirbag
System on page 1-78.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then the
light should go out. This
means the system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.

Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeAnti-Lock Brake
System Warning Light on page 3-40andTowing Your
Vehicle on page 4-34.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.

Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or Check Engine Light
in Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or check
engine light comes on to indicate that there is a problem
and service is required. Malfunctions often will be
indicated by the system before any problem is apparent.This may prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. United States

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady, see “If
the Light Is On Steady” following.If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
ashing, follow the previous steps, and see your dealer
for service as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your Tank on page 5-8. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

Highbeam On Light
This light will come on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.
Fuel Gage
When the indicator nears
empty, you still have a little
fuel left, but you should
get more soon.
If your fuel is low, the warning message in the message
center will come on. SeeLow Fuel Warning Message
on page 3-52.
Your fuel gage tells you about how much fuel you have
left when the ignition is on.
