ECU CHEVROLET BLAZER 1996 2.G Owner's Manual

Downloaded from www.Manualslib.com manuals search engine Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling
a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each of these is covered
in this
manual, and the Index will help you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The light duty trailer wiring is a six-wire harness
assembly. The heavy duty trailer wiring is an eight-wire
harness assembly. The harnesses are stored under
the
vehicle, along the passenger-side frame crossmember on
two-door vehicles or on the driver’s side corner frame
crossmember
on four-door vehicles. The heavy duty
trailer wiring has a 30-amp feed wire with an inline fuse
located by the junction block. See “Fuses and Circuit
Breakers” in
the Index. Both harnesses have no
connector 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 or
auxiliary wiring.
RED: Use for battery charging; it connects to the
starter solenoid (eight-wire harness
only).
LIGHT GREEN: Back-up lamps (eight-wire
harness only).
BROWN: Taillamps and parking lamps.
YELLOW Left stoplamp and turn signal.
DARK GREEN: Right stoplamp and turn signal.
WHITE (Heavy Gage): Ground wire.
WHITE (Light Gage): Auxiliary 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.

Try to have a GM dealer or a professional towing
service tow your vehicle. See “Roadside Assistance” in
the Index.
If your vehicle has been changed since it was
factory-new by adding things like fog lamps, aero
skirting, or special tires and wheels, these instructions
may not be correct.
,Before you do anything, turn on the hazard
warning flashers.
When
you call, tell the towing service:
Whether your vehicle has rear-wheel drive,
The make, model and year of your vehicle.
Whether you can move the shift lever for the

Downloaded from www.Manualslib.com manuals search engine 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. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components. When your vehicle
is being towed, have the ignition
key turned to the
OFF position. The steering wheel
should be clamped
in a straight-ahead position with a
clamping device designed for towing service. Do not
use the vehicle's steering column lock for this. The
transmission should be in
NEUTRAL (N) and the
transfer case, if you have one, should be
in 2HI. The
parking brake should be released.
Don't have
your vehicle towed on the drive wheels
unless
you must. If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later
in this section or your transmission will
be damaged.
If these limitations must be exceeded, then
the drive wheels have to be supported on a dolly.

Downloaded from www.Manualslib.com manuals search engine Tire Chains
NOTICE:
If your vehicle has P235/75R15, P235/70R15 or
31xlOSOR15LT/C size tires, don’t use tire chains.
They can damage your vehicle.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE Class “S” type chains that are the proper
size for your tires. Install them on the drive axle
tires (four-wheel-drive vehicles can use chains on
both axles) 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.
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
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all
be hazardous -- some more than
others
-- and they can all damage your vehicle, too.
