Downloaded from www.Manualslib.com manuals search engine DISC BRAKE WEAR INDICATORS
Front disc brakes have bum-in we .ar indicators which are desigled to make a
high-pitched squeating or
cricket·tike warning sound when the brake pads are
worn to where new pads are needed . The sound will come
and go. or be heard
all the time when the wheels are rolling, but will stop when the brake pedal is
pushed down
firmly. Expensive damage can result if pads are not replaced When needed .
See also the brake checks listed in the Maintenance Schedule folder.
INSTRUMENT PANEL AND CONTROLS
INSTRUMENTS
The instruments . gages and indicator lights convenienlly grouped in the
instrument cluster are designed to tell you at a glance many important things
about the perform ance of your
vehicle. The following information will enabl e
you to more quickly understand and properly interpret these instruments.
Speedometer
The speedometer hand indicates vehicle speed in miles per hour and
kilometers per hour.

The group of six figures in the, speedometer lower center sectiori indicates the
accumulated mileage.
Trip Odometer (optional)
The trip odometer may be reset to zero by turning stem to. the right This
instrument may be used to 1TI<\':!1 .. aPC~rately record trip mileages 'or kilometers .
Fuel Gage
The fuel gage will register the APPROXIMATE fuel level in the tank. when the
ignition is in the
RUN position .
When the
gage registers EMPTY. some fuel is still available as a reserve .
When the gage registers FULL. some
additional fuel can still be added to the
tank. The following conditions maybe considered normal:
•
Gas station pump may shut off before fuel gage indicates FULL
• Amount of gasoline reqUired ior fill~up may not exaclly correspond to gage.

This light will come on to prov~ a "bulb check", when the ignition is turnee
on, but should go out after the engine is startee. If light fails to come on with
ignition turnee on,
it could indicate a bumee -out bulb , a defective electric
choke heater circuit or a
blown instrument lamp fuse. Have system repairee if
light
does not come on during check.
Occasionally, this light may flicker . momentarily while the engine is running but
this will· not harm ,the ' system. However, if the ,light remains on during normal
engine operation , the engine shoutd be stopped until the cause of the
trouble can be Iocatee .andcorrectee. The source of the troubte could be any of the following.
•
Loss of engine oil pressure.
• Blown "Choke Heater" or Gage fuse.
• Loss of electric choke heater vo~age.
NOTICE: Continuing to run the engine with an illuminated oil/choke pressure light can cause serious damage to the engine or unusually high exhaust system temp*'ratures which could resuh in serious d8mage to the vehicte.
Choke Warning Indicator Light
On some vehicles equippec with tlie optional .Oil pressure gage, an amber
choke warning indicator
-light replaces the red oil pressure ' indicator light in the
instrument cluster. If this light comes on, indicating loss of electric choke
heater voltage , have your authorizee
Oealer locate and correct the trouble as
soon as possible.
Generator Indicator Light
The red .light VOLT is designee to come on when the ignition.key is in the "run " pos~ion,bul t>efiJrethe 'engine;;, startee. After the engine starts, the
light should go out and remain oul.

"'''''''~''., ENGINE" LIGHT
All gasoline"~~gine VehiCles sold in ttwl,lnited States (aridsorne ' vehidle. sok:!
in Canada) have the Computer Command Control sYstem, (canadian owners
should
also ' read the Nole on the. inside front cover of this manual. )
If your vehicle has thElCoTP\Jter :,eommand:'ContrOI-system, ,a , "CHECK
ENGINE" light
on the instrument panel is designed to come on during engine
starting to let you know the bulb is working ; (The light will stay on a short time .
after
the engine starts,) If the light comes on while driving, service to the
Computer , Command
Control system may be required , Although. the. v.ehicle
may still be drivable, see , your Chevrolet dealer as soon as possible . for an inspection of the system , (Some vehicles sold in Canada, DO NOT HAVE the
Computer Command Controtsystem ,
ILyeur vehicle does not have a "Check
Engine " light, then it does not have the Computer Command Control system,)
Continued, driving without having the Computer Command Control system
serviced
could cause damegeto' the emission control system, It could also affect fuel economy and drivability, .
See also "Computer
Command Control' system" in "Service and Maintenance," Section: 5 of this manual.
Tachometer
The optional tachometer i. ndicates the speed of the engine in revolutions per
minute, The' indicated num,ber, times 100, gives the engine speed, Operating
the engine
with. the tachometer . reading .in the colQr-coded high-speed area could lead to seriOUS engine damage,

Downloaded from www.Manualslib.com manuals search engine When the ignition key is turned to the OFF position, the pointer may nO\". necessarily return to the 0 RPM position. For the tachometer to regster 0 RPM .
the key
must be in the RUN position and engine not running.
Engine Temperature Gage
This gage indicates coolant temperature which will vary with air temperature
and operating
cond~ions. The ignition must be on for accurate readings. Hard
driving
or prolonged idling in very hot weather will cause the pointer to move
beyond the center of the band. Should pcinter move to the line at the "H" end
of the band , see "Engine Cooling
System" on page 3-3.
Voltmeter
When the engine is operating, the voltmeter indicates the electrical system
voltage. During minimum electrical load, the pointer will read
to the right of the
center. As the electrical load is
increaSed, or in stop-and-go driving, the pointer
will rotate to the
left . A meter reading continuously in the left or right red zone
indicates an electrical system failure. Cause of the failure should be determined
and corrected.
Oil Pressure Gage
The oil pressure gage indicates the pressure at which oil is being delivered to
the various parts of the engine requiring lubrication. Pressures registered by the gage may vary according to outside air temperatures or weight of oil being
used. Oil pressure
of a cold engine being operated at a given speed will be
somewhat higher than when the engine is at normal operating temperature at
the same speed. Prolonged high speed operation on a hot day at the given
speed will result
in somewhat lower oil pressure readings. Readings of 205 to
275 kPa (30 to 40 psi) may be considered normal during moderate road
speeds of 35 to 40 mph (55 to 60 km/h) with the engine at proper operating
temperature . Gage readi'rig;rwhich are ·consistently high or low under these
conditions may indicate lubrication system and/or engine malfunction.
