Will the trailer brake parts take 3,000 psi (20 650 Wa) of Ijressure? If
not, the trailer brake system must not be used with your vehicle.
Driving with a Trailer
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.

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.
Jump Starting
If your battery (or batteries) 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.
A CAUTION:
Batteries can hurt you. They can be dangerous because:
They contain acid that can burn you.
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.

To wing Your Vehicle
Try to have your GM dealer or a professional towing service tow your
vehicle. They can provide the right equipment and know how to tow
it
without damage.
If your vehicle has been changed since
it was factory-new. by adding such
things like fog lamps, aero skirting,
or special tires and wheels, these things
could be damaged during towing.
Before you do anything,
turn on the hazard warning flashers.
When you call, tell the towing service:
0 That your vehicle has rear-wheel drive, or that it has the four-wheel
drive option.
The make, model, and year of your vehicle.
0 Whether you can move the shift lever for the transmission and transfer
case,
if you have one.
If there was an accident. what was damaged.
A CAUTION:
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is being towed.
0 Never tow faster than safe or posted speeds.
0 Never tow with damaged parts not fuIly secured.
0 Never get under your vehicle after it has been lifted by the
tow truck.
0 Always use separate safety chains on each side when towing a
vehicle.
0 For pickups (except cab chassis models), use T-hooks on front
. of vehicle, J-hooks on rear.
For cab chassis models, use J-hooks on front and rear of
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 designed for towing, service.
Do not use the vehicle’s steering
column lock for this. The transmission and transfer case, if
you have one,
should be
in NEUTRAL (N) and the parking brake released.

Engine Fan Noise
Your vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster
to provide more air to cool the engine. In most every day
driving conditions the fan is spinning slower and the clutch is
not fully
engaged. This improves fuel economy and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or high outside temperatures, the fan
speed increases as the clutch more fully engages.
So you may hear an
increase
in fan noise. This is normal and should not be mistaken as the
transmission slipping or making extra shifts.
It is merely the cooling system
functioning properly. The fan will slow down when additional cooling is not
required and the clutch partially disengages.
You may also hear this fan noise when you start the engine. It will go away
as the
fan clutch partially disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out
of a tire, it’s much more likely to
leak out slowly. But if you should ever have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel firmly, Steer
to maintain lane position, then gently brake to a
stop well out of
the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout, remove
your
foot from the accelerator pedal. Get the vehicle under control by
steering the way
you want the vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake to a stop, well
off the road if
possible.
If a tire goes flat, the next part shows how to use your jacking equipment to
change a flat tire safely.

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 nlust use caution.
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 par\
ts
of the vehicle can overheat. That could cause an engine
compartment fire or other damage. When you’re stuck, spin th\
e wheels
as little as possible. Don’t spin the wheels above 35 mph
(55 km/h) as shown on the speedometer.
I NOTICE:
Spinning your wheels can destroy parts of your vehicle as well as
the tires. If you spin the wheels too fast while shifting your
transmission back and forth, you can destroy your transmission.
For information about using tire chains on your vehicle, see “Tire Chains”
in the Index.
Rocking
your vehicle to get it out:
First. turn your steering wheel left and right. That will clear the area around
your front wheels. Then shift back and forth between REVERSE
(R) and a
forward gear (or
with a manual transmission, between FIRST (1 ) or
SECOND (2) gear and REVERSE), spinning the wheels as little as possible.
Release
the accelerator pedal while you shift, and press lightly on the
accelerator pedal when the transmission
is in gear. If that doesn’t get you
out after a few tries, you may need
to be towed out. Or, you can use your
recovery hooks,
if your vehicle has them. If you do need to be towed out.
see “Towing Your Vehicle”
in the Index.

NOTICE:
Your surge tank pressure cap is a unique 15 psi (105 kPa)
pressure-type cap for use with surge tank cooling systems only.
It must be tightly installed to prevent coolant loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the top tube of the coolant surge tank.
Thermostat
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the flow
of coolant through the
radiator until the coolant reaches a preset temperature.
When you replace your thermostat, an AC@ thermostat is recommended.
Power Steering Fluid
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap and wipe \
the
dipstick with a clean rag. Replace the cap and completely tighten it. Then
remove the cap again and look at the fluid level on the dips\
tick.
The level should be at the
FULL COLD mark. Add enough fluid to bring
the level
up to the mark.
A fluid loss in this system could indicate a problem. Have the system
inspected and repaired.
