ECU CHEVROLET VENTURE 2003 1.G Workshop Manual

Driving with a Trailer
{CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness or death. See ªEngine
Exhaustº in the Index. To maximize your safety
when towing a trailer:
·Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
·Keep the rear-most windows closed.
·If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. See ªClimate Controlsº in
the Index.Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.

How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter, remove the ®lter from
the vehicle and lightly shake the ®lter to release
loose dust and dirt. If the ®lter remains ªcakedº with dirt,
a new ®lter is required.
To inspect or replace the air cleaner/®lter, do the
following:
1. Remove the two clamps on the duct.
2. Remove the duct.
3. Unlatch the two hooks on top of the engine air
cleaner/®lter housing.4. Remove and replace the engine air cleaner/®lter.
5. Align the tabs located on the bottom of the
panel with the slots at the bottom of the housing.
6. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs are seated
correctly in the slots.
7. Put the duct back on and reinstall the clamps.
{CAUTION:
Operating the engine with the air cleaner/®lter
off can cause you or others to be burned. The
air cleaner not only cleans the air, it helps to
stop ¯ame if the engine back®res. If it is not
there and the engine back®res, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/®lter off.
Notice:If the air cleaner/®lter is off, a back®re can
cause a damaging engine ®re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/®lter in place when
you're driving.

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page 5-63andWheel Replacement
on page 5-66for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire, If it moves,
use the folding wrench to tighten the cable. See
Changing a Flat Tire on page 5-71.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See ªPart A: Scheduled
Maintenance Services,º in Section 6, for scheduled
rotation intervals.When rotating your tires, always use the correct rotation
pattern shown here.
Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the
Certi®cation/Tire label. Make certain that all wheel nuts
are properly tightened. See ªWheel Nut Torqueº
under
Capacities and Speci®cations on page 5-103.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. See ªChanging a Flat
Tireº in the Index.
5-62

{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
See
Changing a Flat Tire on page 5-71for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used
or how far it's been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class ªSº type chains
that are the proper size for your tires. Install them
on the front tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer's
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.

about 10 minutes. The light in the switch will blink. After
about one minute you can use the system again.
Press the switch and the indicator light will come on.
Notice:If you run the accessory in¯ator longer than
30 minutes at a time, you could damage the
in¯ator. The repairs would not be covered by your
warranty. Run the in¯ator for short periods of
time only.After running the accessory in¯ator for 30 minutes, wait
at least 10 minutes before restarting the accessory
in¯ator.
To turn off the in¯ator, do the following:
1. Press the switch and detach the hose, ®rst from the
in¯ated object, then from the outlet.
2. Put the protective cap back on.

Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation. See ªCapacities and
Speci®cationsº in the index for the wheel nut torque
speci®cation.
10. Don't try to put a wheel cover on the compact spare
tire. It won't ®t. Store the wheel cover securely in
the rear of the vehicle until you have the ¯at
tire repaired or replaced.
Notice:Wheel covers will not ®t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.
Storing a Flat or Spare Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down. If
the spare tire is stored with the valve stem
pointing upwards, its secondary latch won't
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing down.

Storing the Spare Tire and Tools
1. Lay the tire near the rear of the vehicle with the
valve stem down.
2. If the vehicle has aluminum wheels, remove the
small center cap by tapping the back of the cap
with the extension of the shaft.
3. Slide the cable retainer through the center of the
wheel and start to raise the tire.
Make sure the retainer is fully seated across the
underside of the wheel.
4. When the tire is almost in the stored position, turn
the tire so the valve is towards the rear of the
vehicle.
This will help when you check and maintain tire
pressure in the spare.
5. Raise the tire fully against the underside of the
vehicle. Continue turning the folding wrench until
you feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is
tight. The spare tire hoist cannot be overtightened.A. Push and Pull
