1993 CHEVROLET SUBURBAN ABS

Cigarette Lighter/Ashtras
PO286
To use the lighter, push it in all the way, and let go. When it’s ready, it will
pop back by itself.
To remove the rear ashtrays, press down on the inside tabs and p\
ull.
Don’t put papers and other things that burn into your ashtr\
ays.
If you do,
cigarettes or other smoking materials could set them on fire, \
causing damage.
Storage Compartments
Your vehicle has a variety of storage compartments provided for your
convenience.

If your engine ever stops while you’re driving, brake normally but don’t
pump your brakes. If you do, the pedal may get harder to push down. If
your engine stops, you will still have some power brake assist. But you
will use it when you brake. Once the power assist is used up, it may
take longer
to stop and the brake pedal will be harder to push.
Anti-lock Brakes (ABS)
Your vehicle has an advanced electronic braking system that can help\
keep it
under control.
When you start your vehicle and begin to drive away, you may hear
a
momentary motor or clicking noise. This is the ABS system testing itself.
AM41 5006
Here’s how anti-lock works. Let’s say the road is wet. Y\
ou’re driving safely.
Suddenly an animal jumps out in front of you.
You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. The computer sepa\
rately
works the brakes at each front wheel and at the rear wheels. \
The anti-lock
system can change the brake pressure faster than any driver co\
uld. The
computer is programmed to make the
most of available tire and road
conditions. You can steer around the obstacle while braking hard.

Loss of Control
Let’s review what driving experts say about what happens whe\
n the three
control systems (brakes, steering and acceleration) don’t ha\
ve enough friction
where the tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying
to steer, and constantly seek an
escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive d\
rivers avoid
most skids by taking reasonable care suited
to existing conditions, and by not
“overdriving” those conditions. But skids are always possib\
le.
The three types of skids correspond
to your vehicle’s three control systems.
In the braking skid your wheels aren’t rolling. In the steering
or cornering
skid,
too much speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid too much throttle causes the
driving wheels to spin.
A cornering skid and an acceleration skid are best handled by easing your
foot off the accelerator pedal. If your vehicle starts to slide (as when you turn
a corner on a wet, snow-
or ice-covered road), ease your foot off the
accelerator pedal as soon as you feel the vehicle start
to slide. Quickly steer
the way you want the vehicle
to go. If you start steering quickly enough, your
vehicle will straighten out. As it does, straighten the front wheels.
Of course, traction is reduced when water, snow, ice, gravel,
or other material
is on the road.
For safety, you’ll want to slow down and adjust your driving to
these conditions.
It is important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control more limit\
ed.
While driving on a surface with reduced traction,
try your best to avoid
sudden steering, acceleration,
or braking (including engine braking by shifting
to a lower gear). Any sudden changes could cause the tires t\
o slide. You
may not realize the surface is slippery until your vehicle is \
skidding. Learn to
recognize warning clues-such as enough water, ice or packed snow on the
road to make a “mirrored surface”-and slow down when you have any\

doubt.
Remember: Any anti-lock braking system (ABS) helps avoid only the braking
skid. Steer the way you want
to go.

Your Driving and the Road
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 pan\
el 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 45 mph (70
kmlh) or less to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission, you should use D (or, as you need to,
a lower gear) 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 and you are to\
wing a
trailer, it’s better not
to use fifth gear, just drive in fourth gear (or, as you
need to, a lower gear).
Parking on Hilk
You really should not park your rig 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
4. Reapply the regular brakes. Then apply your parking brake, and \
then
chocks absorb the load.
shift
to P (Park), or R (Reverse) for a manual transmission.
5. If you have a four-wheel-drive vehicle, be sure the transfer case \
is in
a
drive gear-not in
N (Neutral).

Service & Appearance Care
Front Suspension and Steering Linkage
Your maintenance schedule will tell you how often to lubricate the fittings. See
“Recommended Fluids and Lubricants” in the Index for the \
proper lubricant to
use.
Front Wheel Bearings
Your vehicle has front wheel bearings that must be cleaned and repa\
cked.
Your maintenance schedule will
tell you how often this must be done.
Front Shock Absorbers
The front shock absorbers of your vehicle do many things. They help the
vehicle ride smoothly and also control the travel of the suspension system.
When the shock absorbers are serviced, any replacement shock ab\
sorbers must be the same as the original equipment shock absorbers in \
both
extended length and strength.
Wheel Nut Torque
For vehicles with dual wheels, when the vehicle, wheel or fast\
eners are new,
have the torque set at the first
100, 1,000 and 6,000 miles (160, 1600 and
9600 km). Use the torque specified in the appropriate Specification \
Chart later
in this section.
Single Belt Accessory Drive
If your new vehicle uses a serpentine belt, it is lighter, and more durable
than systems with several belts.
The belt runs over or around the pulleys on the engine.
A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier. If you need
to replace the belt, be sure to get the correct
replacement belt. Your dealership or parts supplier can help you with this.
The Accessory Drive Belt Routing label on your vehicle will sh\
ow you how to route the belt your vehicle uses.
