1994 CHEVROLET S10 warning

Downloaded from www.Manualslib.com manuals search engine running at 2,000 revolutions per minute (rpm). The tachometer needle will
vary all the time that the engine is running.
The yellow warning range tells you that your engine speed is reach\
ing its
upper limits. Don’t drive very long with the tachometer in the yellow range.
If you have a manual transmission, shift to a higher gear as soon as possible.
If you have an automatic transmission, lift your foot off
of the accelerator
pedal
so that the transmission can select a higher gear.
The Red danger range tells you that your engine speed is at its upper limits.
You should immediately shift to a higher gear, or lift your foot
off of the
accelerator pedal. If you drive for very long with the tachometer in the red
danger range, engine damage will result.
NOTICE:
Do not operate the engine with the tachometer in the red area,
or engine damage
will occur.

Warning Lightsy Gages and Indicators
This section describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong be\
fore it
becomes serious enough to cause an expensive repair or replacem\
ent.
Paying attention to your warning lights and gages could also s\
ave you or
others from injury.
Warning lights
go on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition\
key just to
let you know they’re working. If you are familiar with this sec\
tion, you
should not
be alarmed when this happens.
Gages can indicate when there may be or is a problem with one
of your
vehicle’s functions. Often gages and warning lights work toge\
ther to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells you what to
do about it. Please follow the manual’s advice.
Waiting to do repairs can be costly
- and even dangerous. So please get to
know your warning lights and gages. They’re a big help.

Downloaded from www.Manualslib.com manuals search engine Brake System Warning Light
Your vehicle hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good braking,
though, you need both parts working well.
Your vehicle also has rear-wheel or four-wheel anti-lock brakes. See \
“Anti-Lock Brakes” in the Index.
If the warning light comes on, there could
be a brake problem with either your regular or rear-wheel anti\
-lock brakes, or both. Have your brake system inspected right away.
This light should come on as you start the vehicle.
If it doesn’t come on
then, have it fixed
so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully. You may notice that the pedal
is harder to push. Or, the pedal may
go closer to the floor. It may take longer to stop.
If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle” in the Index.)
The brake system warning light
will also come on when you set your
parking brake, and it will stay on
if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it means you have a
brake problem.

If your vehicle has
four-wheel anti-lock
brakes, it will have
this yellow light.

With anti-lock, this light will go on when you start your engine and may
stay on for several seconds. That’s normal. If the light doesn’t come \
on,
have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving, your vehic\
le needs
service.
If the regular brake system warning light isn’t on, you still \
have
brakes, but you don’t have anti-lock brakes.
If the regular brake system
warning light is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Engine Coolant Temperature Gage
I This gage shows the
engine coolant
temperature. If the
gage pointer moves
into the red area, your
engine is too hot!
It means that your engine coolant has overheated. If you have been
operating your vehicle under normal driving conditions, you shou\
ld pull
off
the road, stop your vehicle and turn off the engine as soon as possible.

Downloaded from www.Manualslib.com manuals search engine Charging System Light
The charging system
light is on your
instrument cluster and will come on briefly
when you turn on the
ignition, but the
engine is not running,
as a check to show
you it is working.
It should
go out once the engine is running. If it stays on, or comes on while
you are driving, you may have a problem with the charging system.
It could
indicate that you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving while this light is on
could drain your battery.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.
Check Gages Light
This Check Gages
light is on the
instrument cluster and
will come on briefly
when you are starting
the engine.
If the light
comes on and stays on while you are driving,
check your various
gages to see
if they are
in the warning zones.

I
When your engine is not running, but the ignition is on (in \
the RUN
position), this gage shows your battery’s state of charge in DC volts. When
the engine is running, the gage shows the condition of the charging system.
Readings between the low and high warning zones indicate the normal
operating range.
You can only drive for a short time with
the reading in either warning zone.
If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a possible problem in the electrical
system. Have
the vehicle serviced as soon as possible.
Center High Mounted Stop Lamp (CHMSL)
Feed Wire
Your vehicle includes a Center High Mounted Stop Lamp (CHMSL) located
above the rear window.
If equipment such as a cap or camper is installed, a wire labeled “Center
High Mounted Stop Lamp (CHMSL)” feed is provided along the left rear
frame. This wire should be used to install a CHMSL in the cap or camper.

Avoid needless heavy braking. Some people drive in spurts - heavy
acceleration followed by heavy braking
- rather than keeping pace with
traffic. This is a mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you do a lot of heavy
braking.
If you keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary braking. That means better
braking and longer brake life.
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\
you
keep it under control.
If your vehicle has an anti-lock brake system warning light on th\
e
instrument panel, it has four-wheel anti-lock brakes. Otherwise, it has
rear-wheel anti-lock brakes. When you start a vehicle that has \
four-wheel anti-lock brakes and begin to drive away, you may hear
a momentary motor
or clicking noise. This is the ABS system testing itself.
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. With four-wheel
anti-lock:
If one of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel
and at the rear wheels. The
four-wheel anti-lock system can change the brake pressure faster\
than any

Downloaded from www.Manualslib.com manuals search engine While driving on a surrace with reaucea traction, try yo best to a td
sudden steering, acceleration, or braking (including engme braki\
ng DY
shifting to a lower gear). Any sudden changes could cause the tires to 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:
If you have the four-wheel anti-lock braking system, it helps
avoid only the braking skid. The rear-wheel anti-lock braking system helps
avoid only a rear braking skid. In a braking skid (where the\
front wheels are
no longer rolling), release enough pressure on the brakes to \
get the front
wheels rolling again. This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly. As long as the front wheels
are rolling, you will have steering control.
Driving Guidelines
Off-Road Driving with Your Four-wheel
Drive Vehicle
This off-road guide is for vehicles that have four-wheel drive.
Also, see “Anti-lock Brakes’’
in the Index.
If your vehicle doesn’t have four-wheel drive, you shouldn’\
t drive off-road
unless you’re on a level, solid surface.
Off-road driving can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system
behind. Traffic lanes aren’t marked. Curves aren’t banked. \
There are no
road signs. Surfaces can be slippery, rough, uphill or downhill\
. In short,
you’ve gone right back to nature.
Off-road driving involves some new skills. And that’s why it\
’s very
important that you read this guide. You’ll find many driving tips and
suggestions. These
will help make your off-road driving safer and more
enjoy able.
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to have
all necessary maintenance and service work done. Be sure
you read all the
information about your four-wheel drive vehicle in this manual. \
Is there
enough fuel?
Is the spare tire fully inflated? Are the fluid levels up where
they should be? What are the local laws that apply to off-roading where
you’ll be driving? If you don’t know, you should check with law
enforcement people in the area. Will you
be on someone’s private land? If
so, be sure to get the necessary permission.

Downloaded from www.Manualslib.com manuals search engine Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy. (See the next part, “Freeway Driving.”)
0 Treat a green light as a warning signal. A traffic light is there because
the corner is busy enough to need it. When a light turns green, and just
before you start to move, check both ways for vehicles that have not
cleared
the intersection or may be running the red light.
Freeway Driving
Mile for mile, freeways (also called thruways, parkways, expressways,
tumplkes, or superhighways) are the safest
of all roads. But they have their
own special rules.
The most important advice on freeway driving is: Keep up with
traffic and
keep to the right. Drive at the
same speed most of the other drivers are
driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the
left lane on a freeway as a passing lane.
At the entrance there is usually a ramp that leads to the freeway. If you have
a clear view of the freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine where you expe\
ct to blend
with the flow. Try to merge into the gap at close to the prevailing s\
peed.
Switch on your turn signal, check your mirrors and glance over your
shoulder
as often as necessary. Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust
your speed to the posted limit or to the
prevailing rate
if it’s slower. Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use your turn signal.
Just before you leave the lane, glance quickly over your shoulder t\
o make
sure there isn’t another vehicle
in your “blind” spot.
