1998 CHEVROLET BLAZER brake

Downloaded from www.Manualslib.com manuals search engine 0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard
on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift to a lower gear when
you go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a
hill. You could crash. Shift down to let your
engine assist your brakes on a steep
, downhill slope.

A CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off
is dangerous. Your brakes will have to
do all the work
of slowing down. They could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going down
a hill. You could crash. Always have your engine
running and your vehicle in gear when you
go downhill.
Know how to go uphill. You may want
to shift down
to a lower gear. The lower gears help cool your
engine and transmission, and
you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
e As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or
an accident.

What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive
on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32” F; OOC) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Accelerate gently. Try
not to break the fragile traction. If
you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
Your anti-lock brakes improve your vehicle’s stability
when
you make a hard stop on a slippery road. Even
though
you have an anti-lock braking system, you’ll
want to begin stopping sooner than
you would on dry
pavement. See “Anti-Lock” in the Index.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until
you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the
sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface
of a curve or an overpass may
remain icy when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

Downloaded from www.Manualslib.com manuals search engine Payload
The payload capacity is shown on the CertificatiodTire
label. This is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part
of your load. If you added any
accessories or equipment after your vehicle
left the
factory, remember to subtract the weight of these things
from the payload. Your dealer can help you with this.
Add-on Equipment
When you carry removable items, you may need to put a
limit
on how many people you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.
NOTICE:
Your warranty doesn’t cover parts or
components that fail because
of overloading.
Towing a Trailer
CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull a trailer only if you have followed all the
~ steps in this section. Ask your dealer for advice
and information about towing a trailer with
~ your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your dealer for
important information about towing a trailer
with your vehicle.

Downloaded from www.Manualslib.com manuals search engine Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains
to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 lbs. (450 kg)
loaded, then it needs its own brakes -- and they must be
adequate. Be sure to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly. Your
trailer’s brake system
can tap into the vehicle’s
hydraulic brake system
only if
The trailer parts can withstand 3,000 psi
(20 650 kPa) of pressure.
The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes.
If everything checks out this far, then make the brake
fluid tap at the
port on the master cylinder that sends
fluid to the rear brakes. But don’t use copper tubing for
this.
If you do, it will bend and finally break off. Use
steel brake tubing.

I
A GA ‘TION:
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 “Engine Exhaust” in the Index.) To
maximize your safety when towing
a trailer:
0 Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
0 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
MAX AfC because it only recirculates the
air inside your vehicle. (See “Comfort
Controls” 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.
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.
4-47

Downloaded from www.Manualslib.com manuals search engine 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.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer
to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and
a heavy-duty turn signal flasher (included in
the optional trailering package).
The arrows
on your instrument panel will flash
whenever
you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned
out. Thus, you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If
you don’t shift
down,
you might have to use your brakes so much that
they would get hot and no longer work well.
When you’re turning with
a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well
in advance. On
a long uphill grade, shift down and reduce your
speed
to around 45 mph (70 kmh) to reduce the
possibility of engine and transmission overheating.
4-48

Downloaded from www.Manualslib.com manuals search engine If you have an automatic transmission, you should use
DRIVE
(D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or, if
you have a manual transmission,
it’s better not to use
FIFTH (5) gear, just drive in
FOURTH
(4) gear (or, as you need to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If
you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably
on level ground)
with the automatic transmission in PARK (P) (or the
manual transmission out
of gear and the parking brake
applied) for a few minutes before turning the engine
off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and the trailer can be damaged. But if you ever have
to park your rig
on a hill, here’s
how
to do it:
1.
2.
3.
4.
5.
6.
Apply your regular brakes, but don’t shift into
PARK
(P) yet, or into gear for a manual
transmission. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P), or
REVERSE
(R) for a manual transmission.
If
you have a four-wheel-drive vehicle with a
manual transfer case shift lever, be sure the transfer
case is
in a drive gear -- not in NEUTRAL (N).
Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 R.elease the parking brake.

3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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 H-T--- ess
The light duty trailer wir is a six-wire harness
assembly. The optional 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 rear 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.
