ignition CHEVROLET VENTURE 2003 1.G Repair Manual

If you put things inside your vehicle ± like suitcases,
tools, packages, or anything else ± they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they'll keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
·Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
·Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
·Don't leave an unsecured child restraint in
your vehicle.
·When you carry something inside the
vehicle, secure it whenever you can.
·Don't leave a seat folded down unless you
need to.
Automatic Level Control
On vehicles equipped with the automatic level control,
the rear of the vehicle is automatically kept level as you
load or unload your vehicle. However, you should still
not exceed the GVWR or the GAWR.
If the engine is running or the ignition key is in
ACCESSORY or when Retained Accessory Power
(RAP) is active, you may hear the compressor operating
when you load or unload your vehicle, and periodically
as the system self-adjusts. This is normal. See
ªRetained Accessory Powerº under
Ignition Positions on
page 2-31.
The compressor should operate for brief periods of time.
If the sound continues for an extended period of time,
your vehicle needs service.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask your
dealer to help you load your vehicle the right away.

How to Reset the Change Engine Oil
Message
The GM Oil Life System calculates when to change
your engine oil and ®lter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
change engine oil message being turned on, reset
the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL is
displayed on the Driver Information Center (DIC).
2. Once OIL is displayed, push and hold the trip/reset
button for ®ve seconds. The number will disappear
and be replaced by 100 (indicating 100% oil life
remaining).
3. Turn the key to OFF.
If the change engine oil message comes back on, the
engine oil life monitor has not reset. Repeat the
procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
®lter before disposal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by taking it
to a place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer, a
service station or a local recycling center for help.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
the location of the engine air cleaner/®lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter every 15,000 miles
(25 000 km) and replace every 30,000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the ®lter at every oil change.

Notice:Ignoring these steps could result in costly
damage to your vehicle that wouldn't be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
won't work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake ®rmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn off
the radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (-) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose.

Accessory In¯ator
Your vehicle may have an accessory in¯ator. With it,
you can in¯ate things like air mattresses and
basketballs, and you can also use it to bring your tires
up to the proper pressure.
The accessory in¯ator is located in the rear
compartment on the driver's side. To remove the
protective cap, pull the tab on the cap.
This symbol is on the
accessory in¯ator switch.
There may be an accessory in¯ator kit stored in the
glove box. It includes a 20-foot (6 m) hose with an air
pressure gage and nozzle adapters.{CAUTION:
In¯ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in¯ator instructions, and
in¯ate any object only to its recommended
pressure.
To use your accessory in¯ator system, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to in¯ate.
4. Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6. Press the accessory in¯ator switch. The light in the
switch will come on to show the system is working.

Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.2. Firmly apply the parking brake. See
Parking Brake
on page 2-38if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the RUN
position, but don't start the engine. Without applying
the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to LOCK in each shift lever position.
·The key should turn to LOCK only when the
shift lever is in PARK (P).
·The key should come out only in LOCK.
