1998 GMC SAVANA Owners Manual

Trailer Wiring Harness
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.
0 Dark Blue: Use for electric trailer brakes (eight-wire
harness only)
Orange: Trailer accessory (eight-wire harness only)
Light Green: Back-up lamps
0 Brown: Parking lamps
0 Yellow: Left stoplamp and turn signal
0 Dark Green: Right stoplamp and turn signal
0 White (heavy gage): Ground wire
0 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
hamess in its original place. Wrap the harness together
and tie it
neatly so it won’t be damaged.

Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have
a problem. Your front and
rear turn signal lamps will flash on and
off.
Push the button at the top of
the steering column all the
way down to
make your
front and rear turn signals
flash on and off.
Your hazard warning flashers work
no matter what
position your key
is in, and even if the key isn’t in.
To turn off the flashers, push the button until the first
click and release.
When the hazard warning flashers are on, your turn
signals won’t work.
Other Warning Devices
If you carry reflective triangles, you can use them to
warn others. Set one up at the side of the road about
300 feet (100 m) behind your vehicle.

. ~p Starting
lr your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But please follow the steps below
to do it safely.
i A CAUTION:
Batteries can hurt you. They can be dangerous
because:
0 They contain acid that can burn you.
0 They contain gas that can explode or ignite.
0 They contain enough electricity to burn you.
If you don’t follow these steps exactly, some or all
of these things can hurt you.
I 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.
1 NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.

If you have a diesel engine vehicle with two batteries
(or more) you should know before you begin that,
especially
in cold weather, you may not be able to
get enough power from
a single battery in another
vehicle to start your diesel engine.
If your vehicle has more than one battery, use the
battery that is under the hood
of the vehicle - this
will reduce the electrical resistance.
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 firmly on both vehicles involved in
the jump start procedure. Put your automatic
transmission
in PARK (P).
3. Turn off the ignition on both vehicles. Turn off all
lamps that aren’t needed,
and radios. This will avoid
sparks and help save both batteries, and could save
your radio.
NOTICE: -1
If you leave your radio on, it could be badly
damaged. The repairs would not be covered by
your warranty.

4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each battery.
An electric fan can start up even when the engme
is not running and can injure you. Keep hands, clothing and tools away from any underhood
electric fan.

A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
Be sure the batteries have enough water. You
don’t need to add water to the ACDelco
Freedom@ battery (or batteries) installed in
every new
GM vehicle. But if a battery has filler
caps, be sure the right amount of fluid is there. If
it is
low, add water to take care of that first. If
you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before
you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to an unpainted
metal engine part or
a body metal surface. Don’t
connect positive
(+) to negative (-) or you will get a
short that would damage the battery and maybe other
parts, too. And don’t connect the negative
(-) to
negative
(-).
Fans or other moving engine parts can injure you
badly. Keep your hands
away from moving parts
once the engine is running.

6. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Or use
a remote positive (+) terminal if the vehicle has one.
7. Don’t let the other end
touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive
(+) terminal if
the vehicle has one.
8. Now connect the black
negative
(-) cable to the
good battery’s
negative
(-) terminal.
Don’t let the other end
touch anything until the
next step.
