ECU CHEVROLET EXPRESS 1997 1.G Owner's Manual

Downloaded from www.Manualslib.com manuals search engine 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.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations
that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need
to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.

The light-duty trailer wiring harness is a six-wire
harness assembly. The optional heavy-duty trailer
wiring package is an eight-wire harness assembly. The
harness is stored under the vehicle, along the driver’s
side rear corner of the frame rail.
The heavy-duty trailer
wiring harness has a 30-amp feed wire. Both harnesses
come without connectors and should be wired by a
qualified electrical technician. The technician can use
the following color code chart when connecting the
wiring harness to your trailer.

Dark Blue: Use for electric trailer brakes (eight-wire
harness only)
Orange: Trailer accessory (eight-wire harness only)
Light Green: Back-up lamps
Brown: Parking lamps
Yellow: Left stoplamp and turn signal
Dark Green: Right stoplamp and turn signal
White (heavy gage): Ground wire
White (light gage): Center high-mounted stoplamp
Securely attach the harness to the trailer, then tape or
strap it
to your vehicle’s frame rail. Be sure you leave it
loose enough
so the wiring doesn’t bend or break, but
not
so loose that it drags on the ground. Store the
harness in its original place. Wrap
the harness together
and
tie it neatly so it won’t be damaged.

Never let passengers ride in a vehicle that is
being towed.
Never tow faster than safe or posted speeds.
Never tow with damaged parts not
fully secured. Never get under your vehicle after it has
been lifted by the tow truck.
Always use separate safety chains on each
side when towing a vehicle.
When your vehicle is being towed, have the ignition
key
off. The steering wheel should be clamped in a
straight-ahead position, with a clamping device
I designed for towing service. Do not use the vehicle’s
steering column lock for this. The transmission should
be
in NEUTRAL (N) and the parking brake should
be released.
A
,!1 CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage.
The vehicle should be tightly secured with
chains or steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle.

Downloaded from www.Manualslib.com manuals search engine If you have a vehicle which was completed from a cab
and chassis, refer to the information from
the body
supplierhstaller.
The spare
tire is a full size tire, like the other tires on
your vehicle.
For cargo vans, and
all passenger vans except
those with the
15 passenger
seating arrangement, the
jack is secured in the rear
passenger side corner
of
the vehicle.
Remove the retaining wing bolt and
lift it off the
mounting bracket. Set the jack and jacking equipment
near the flat tire. For vans
with the 15 passenger
seating arrangement,
the jack is secured
on the rear passenger side floor of
the vehicle.
Remove
the retaining wing bolt and lift it out of the
mounting bracket. Set the jack and jacking equipment
near the flat tire.

the hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will hear two “clicks” when the tire is up all the
way. Try to move the tire with your hands to make
sure
it is securely in place.
Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you
must use caution.
I
A CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission
or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 kmk) as shown
on the speedometer.

Downloaded from www.Manualslib.com manuals search engine Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use chains that are the proper size
for your tires. Install them on the tires of the
rear axle.
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.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst
into flame if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you use anything from a container to clean your
vehicle, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
0 Benzene
0 Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
0 Lacquer Thinner
Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
