1994 CHEVROLET S10 tires

Downloaded from www.Manualslib.com manuals search engine A B
If you’re using a “dead-weight” hitch, the trailer tong\
ue (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 lirnit for cold tires. You’ll find
these numbers on the Certification label on the driver’s doo\
r 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. Crosswind\
s, large trucks
going by, and rough roads are a few reasons why you’ll nee\
d the right hitch.
Here are some rules to follow:
If you’ll be pulling a trailer that, when loaded, will weigh m\
ore 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.
NOTlCE:
If your vehicle has the bumper delete option, do not bolt any
type
of hitch to the close-out panel. The close-out panel will not
support
a hitch.

Downloaded from www.Manualslib.com manuals search engine You can tow trailers to 2,000 pounds (900 kg) with a step bumper hitch, but
if your trailer tongue has a V-shaped foot, your bumper could be damaged
in sharp turns. Check the distance from the front edge of the foot to the
middle of the hitch ball socket.
If the distance is less than 12 inches, take the
foot
off the trailer tongue.
Safety Chains
You should always attach chains between your vehicle and your trail\
er.
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.
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 bE---:s
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 Pa) 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. Acquai\
nt 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 th\
e trailer has
electric brakes, start your vehicle and trailer moving and then\
apply the

Try to have a 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 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:

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 firrnly. Steer to maintain lane position, then g\
ently 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 co\
ntrol 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.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place. Turn on your hazard waming flashers.

Downloaded from www.Manualslib.com manuals search engine Storing The Jacking Equipment
Return the jack, wheel wrench and wheel blocks to the proper location
behind the seat. Secure the items
and replace the jack cover.
NOTICE:
Don’t use the existing hoist to store a tire with an aluminum
wheel or it could damage the wheel. Secure the tire in the pickup
bed.
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. The method
known as “rocking” can help you get out when you’re
stuck, but
you must use caution.
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.

Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high\
-pitched warning sound when the brake pads are worn and new pads are \
needed. The
sound may come and go or be heard
all the time your vehicle is moving
(except when you -are pushing on the brake pedal
firmly).
I NOTICE:
I
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal w\
hen the
brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear
drum brakes don’t have wear indicators, but if you ever hear a
rear brake rabbing noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each time the\
tires itre
removed for rotation or changing. When you have the front brakes replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, o\
r if
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes adjust for wear.
If your brake pedal goes down farther than normal, your rear drum brakes
may need adjustment. Adjust them by backing up and
firmly applying the
brakes a few times.

This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.
Loading Your Vehicle
The CertificatiodTire label is found on the driver’s door lock pillar. The
label shows the size of your original tires and the inflation pressures needed
to obtain the
gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of
the vehicle,
all occupants, fuel and cargo.
The CertificatiodTire label
also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating
(GAWR). To find out
the actual
loads on your front and rear axles, you need to go to a weigh
station and weigh
your vehicle. Your dealer can help you with this. Be sure
to spread out your load equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the Gross Axle Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, you should spread it out.
