1994 CHEVROLET BLAZER Owners Manual

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves fuel. When you run
the engine, make it go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that
you get and it keeps
the battery charged. You will need a well-charged battery (or batteries)
to
restart the vehicle, and possibly for signaling later on with your headlights.
Let the heater run for awhile.
Then, shut the engine
off and close the window almost all the way to
preserve the heat. Start the engine again and repeat this only when you feel
really uncomfortable from the cold. But
do it as little as possible. Preserve
the fuel as long as you can.
To help keep warm, you can get out of the
vehicle and do some fairly vigorous exercises every half hour or
so until
help comes.
Recreational Vehicle To wing
(Four-wheel Drive
Only)
If your vehicle has 4-wheel drive, you may tow it behind another vehicle
providing it does
not have the optional electronic shift transfer case.
Recreational vehicle towing is not recommended for vehicles
with the optional electronic shift transfer case because the
electronic shift has no neutral position.

Removal of either propeller shaft is unnecessary.
1. Release the parking brake only after the vehicle being towed is firmly
attached to the tow vehicle.
2. Insert the ignition key into the ignition switch and turn it one notch
forward
of the LOCK position. This places the key into the OFF
position, which unlocks the steering column while preventing battery
drain. Unlocking the steering

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 section, and see your
GM
dealer for important information about towing a trailer with
your vehicle.
Every vehicle is ready for some trailer towing. If it was built with trailering
options, as many are, it’s ready for heavier trailers. But trailering
is different
than just driving your vehicle by itself. Trailering means changes
in
handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for this section.
In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers.
So please read this section carefully before you
pull
a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
0 There are many different laws having to do with trailering. Make sure
your rig will be legal, not only where you
live but also where you’ll be
driving.
A good source for this information can be state or provincial
police.
Consider using a sway control if your trailer will weigh 2,000 pounds
(900 kg) or less. You should always use a sway control if your trailer
will weigh more than
2,000 pounds (900 kg).
You can ask a hitch dealer about sway controls.
4-37

Downloaded from www.Manualslib.com manuals search engine Don’t tow a trailer at all during the first 500 miles (800 km) your new
vehicle
is driven. Your engine, axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and don’t make starts at full throttle. This
helps your engine and other parts
of your vehicle wear in at the heavier
loads.
Three important considerations have
to do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example, speed, altitude,
road grades, outside temperature and how much your vehicle
is used to pull
a trailer are all important. And,
it can also depend on any special equipment
that
you have on your vehicle.
You can ask your dealer for our trailering information or advice, or
you can
write
us at the address listed in your Warranty and Owner Assistance
Information Booklet.
In Canada, write to General Motors
of Canada Limited, Customer
Assistance Center,
1908 Colonel Sam Drive, Oshawa, Ontario LlH 8P7.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight to measure
because it affects the total or gross weight of your vehicle. The gross vehicle
weight (GVW) includes
the curb weight of the vehicle, any cargo you may
carry in it, and the people who will be riding
in the vehicle. And if you will
tow
a trailer, you must add the tongue load to the GVW because your
vehicle will be carrying
that weight, too. See “Loading Your Vehicle” in the
Index for more information about your vehicle’s maximum load capacity.
B A
4-38

Downloaded from www.Manualslib.com manuals search engine If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh
10%
of the total loaded trailer weight (B). If you have a
“weight-distributing” hitch, the trailer tongue (A) should weigh 12% of the
total loaded trailer weight (B).
After you’ve loaded your trailer, weigh the trailer and then the tongue,
separately,
to see if the weights are proper. If they aren’t, you may be able to
get them right simply by moving some items around
in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for cold tires. You’ll find
these numbers
on the Certification label on the driver’s door lock pillar or
see “Tire Loading”
in the Index. Then be sure you don’t go over the GVW
limit for your vehicle.
Hitches
It’s important to have the correct hitch equipment. Crosswinds, large trucks
going by, and rough roads are
a few reasons why you’ll need the right hitch.
Here are some rules
to follow:
If you’ll be pulling a trailer that, when loaded, will weigh more than
2,000 pounds (900 kg), be sure to use a properly mounted,
weight-distributing hitch and sway control of the proper size. This
equipment is very important for proper vehicle loading and good
handling when you’re driving.
0 Will you have to make any holes in the body of your vehicle when you
install a trailer hitch? If you do, then be sure to seal the holes later
when
you remove the hitch. If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can get
into your vehicle (see
“Carbon Monoxide”
in the Index). Dirt and water can, too.
If your vehicle has a deadweight hitch and a endgate-mounted spare tire,
and your trailer has
a winch or tongue jack, you could have interference
between them.
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. Always leave just enough slack
so you can turn with
your rig. And, never allow safety chains
to drag on the ground.

Downloaded from www.Manualslib.com manuals search engine Trailer Brakes
If your trailer weighs more than 1,000 pounds (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 brakes system can tap into vehicle’s hydraulic brake system
except:
Don’t tap into your vehicle’s brake system
if the trailer’s brake system will
use more than 0.02 cubic inch (0.3~~) of fluid from your vehicle’s master
cylinder.
If it does, both braking systems won’t work well. You could even
lose your brakes.
Will the trailer parts take
3,000 psi (20 650 kPa) of pressure? If not, the
trailer brake system must not be used with your vehicle.
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.
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
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, 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.
4-40

Downloaded from www.Manualslib.com manuals search engine During your trip, check occasionally to be sure that the load is secure, and
that
the lights and any trailer brakes are still working.
Following Disfance
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.
4-41

Downloaded from www.Manualslib.com manuals search engine Making Turns
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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows
on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green 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.
On a long uphill grade, shift down and reduce your speed
to around 45 mph
(70 kdh) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission,
you should use “D” when towing a
trailer. Operating your vehicle in “D” when towing a trailer will minimize
heat buildup and extend the
life of your transmission. Or, if you have a
manual transmission with
fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
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. Apply your regular brakes, but don’t shift into “P” (Park) yet, or into
gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.
