CHEVROLET BLAZER 1998 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour
(kmh).
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then it must be. But
if
it can’t, then it’s set at zero, and a label must be put on
the driver’s door to show the old mileage reading when
the new odometer was installed.
Wip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To view the trip odometer, press the button near the
readout. To reset the trip odometer, hold the button
until
it resets.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
per minute (rpm). Each tachometer
has a different limit depending on the
powertrain in your vehicle. The tachometer has three
areas: normal operating range, red warning range and
red danger range.
The normal operating range shows your engine speed
during normal driving conditions. For example, when
the needle points to 2, it means the engine
is running at
2,000 revolutions per minute (rpm). The tachometer
needle
will vary all the time that the engine is running.
The shaded red warning range tells you that your engine
speed is reaching its upper limits. Don’t drive very long
with the tachometer in the red warning 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 the accelerator pedal.
The solid 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 the
accelerator pedal.
I NOTICE:
Do not operate the engine with the tachometer in
the red range, or engine damage will occur.

Downloaded from www.Manualslib.com manuals search engine Warning Lights, Gages and Indicators
This part 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 before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages
could also save you or
others from injury.
Warning lights come 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 start the
engine just to let
you know they’re working. If you are
familiar with this section, 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 together 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 this 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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come
on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come
on and stay on
for about
20 seconds,
then it will flash for about
55 seconds. If the driver’s
belt
is already buckled,
neither the chime nor the
light will come
on.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells
you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more information on the air bag system, see “Air Bag” in
the Index.
This light will come
on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
Charging System Indicator Light
If the air bag readiness light stays on after you start the
engine or comes on when
you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem. The
charging system light
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.

Downloaded from www.Manualslib.com manuals search engine Vo1’-- - - -* Gage
I When your engine is not
running, but the ignition is
on (in
RUN), 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.
Readings in the low warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for
an
extended period. This condition is normal since the
charging system is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power. 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.
Shift Light
You have the shift light if
you have a manual
transmission.
This light
comes on very briefly as a
SHIFT
bulb check when you start
the engine.
Shifting when the indicator light is on will help you get
the best fuel economy. See “Shift Light” in the Index.

Downloaded from www.Manualslib.com manuals search engine Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parlung brake. The light
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.
Your vehicle’s 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.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come
(0) (8>
the ignition key to RUN. If
on briefly when you turn
it
doesn’t come on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
BRAKE
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.)
’ A CAUTl IN:
F--
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident.
If the light is still on after you’ve
pulled
off the road and stopped carefully, have
the vehicle towed for service.

Downloaded from www.Manualslib.com manuals search engine Anti-Lock Brake System Warning Light
With the anti-lock brake system, this light will come
on when you start your
engine and may stay
on for several seconds.
That’s normal.
If the light stays
on, or comes on when you’re driving,
your vehicle 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 section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn
you if there is a problem.
Engine Coolant Temperature Gage
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 should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
In “Problems
on the Road,” this manual show you what
to do. See “Engine Overheating’’ in the Index.

SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on
to indicate that there is a problem and service
is required. Malfunctions often will be indicated by
the system before any problem
is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come
on during a malfunction in one
of two ways:
0
0
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle. Dealer
or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.
2-73

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service. You may be
able to correct the emission system
malfunction by considering the following:
Did you recently
put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if the fuel
cap has been left
off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light
off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when
the electrical system
dries out. A few driving trips should
turn the light off.
2-74

Downloaded from www.Manualslib.com manuals search engine Have you recently changed brands of fu.el?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light
turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix
any mechanical or electrical
problems that may have developed.
Engine Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine is running.
Canadian vehicles indicate pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
2-75

Downloaded from www.Manualslib.com manuals search engine A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
Don’t keep driving
if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire.
You or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
I NOTICE:
Security Warning Light
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
SECURITY
This light will come on
briefly when
you turn the
key toward START. The
light will stay
on until the
engine starts.
If the light flashes, the Passlock
system has entered a
tamper mode. If the vehicle fails
to start, see “Passlock”
in the Index.
If the light comes on continuously while driving and
stays
on, there may be a problem with the Passlock
system. Your vehicle will not be protected bv Passlock,
and you should see your dealer.
