STARTING AND OPERATING
ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE)
Do not breathe exhaust gas because it contains carbon monoxide, which by
itself has no color or odor. Carbon monoxide is a dangerous gas. It can cause
unconsciousness and can be lethal.
If
at any time you think exhaust fumes are entering the vehicle, have the cause
determined and corrected
assdon.as possible. If you must drive under. lhese conditions , drive only wilh All windows fully OPEN .
To allow proper operation of your vehicle's ventilation system, keep the.air inlet grille in front of the windShield clear of snow, leaves or other obstructions at all
times.
Protect against carbon monoxide entry into the vehicle body . The best way is to keep the engine exhaust system, vehicle body and body ventilation system
properly maintained. We recommend that the exhaust system and body be inspected by a competent lechniclan :
•
each time the vehicle is raised for an oil change;
• whenever a change is noticed in the sound of the exhaust system;
• whenever the exhaust system, underbody or rear of the vehicle is damaged or. becomes corroded .
See your Miiintenance Schedule folder for parts recuiring inspection.
To allow proper operation of your vehicle's ventilation system, keep the air inlet
grille
in front of the windshi~1d clear of snow, leaves or other obstructions at all
times.
Do not perk or idle this vehicle for more than 10 minutes with the ventilation
system control switch in the "off" position while the engine is running . Even
with
the ventilation system on, running the engine while parked is not recommended . Entry of carbon monoxide into the vehicle body is possible with
a
poorly repaired , damaged, or corroded exhaust system or body.
Do
not run the. engine in CONFINED areas (such as garages or next to a
building) any more than needed to move the vehicle . When Ih.e vehicle has to be stopped in an UNCONFINED area with the engine running for any more
than a few minutes, take the following stepa :
A. Adjust the heating
or cooling ' system to force outside air into the vehicle as
follows:
1. On vehicles not ecuipped wijh air condijioning, set the fan to medium or high speed and the upper control lever to any position except
"Off."
2. On vehicles ecuipped with air conditioning , set the fan to medium or
high speed and the upper control lever to any position except "Off" or
"Max., "
B . Keep the exhaust tailpipe area clear 01 snow and other material to help
reduce the
buildup 01 exhaust gases under the vehicle.

Downloaded from www.Manualslib.com manuals search engine FUEL REQUIREMENTS
Your engine is designed to use only unleaded gasoline . Unleaded gasoline must be uSed for the emission control system to operate properly . Its use will
also reduce spark
plug fouling, exhaust .system corrosion and engine oil deterioration.
Using
leaded gaso~ne can damage the emission control system and could
result
in loss of warranty coverage. The effectiveness of the catalyst in the
catalytic converter decreases after use of as little as one tank of leaded
gasoline.
Also, your vehicle may have the "Computer Command Control" system, which includes an oxygen sensor. Leaded gasoline will damage the
sensor,
and attect emissioncont(ols. (For more information, see "Computer
Command Control
System" in "Service and Maintenance,"Section 5 of this manual. Federal regulations require that pumps delivering unleaded-gasoline
be labeled with the word UNLEADED. Only these pumps have nozzles whichftl the filler neck of your vehicle's gasoline tank.
In the United States, Federal law also requires that gasoline octane ratings be
posted on the pumps. The octane rating shown is an average of Research
octane (R) and Moto< octane (M). In most parts of the United States , you
should use unleaded gasoline with an octane rating of at least 87. However,
you may use unleaded gasoline with an Q!;tane rating as low as 85 in these
. high -altitude areas: Coloraclo , Montana, New Mexico , Utah , Wyoming,
northeastern Nevada, southern Idaho, western South Dakota, and that part of
Texas which is directly south of New Mexico .
Using unleaded gasoline with
an octane rating lower than stated above can
cause persistent, heavy
"spark knock." (" Spark knock" is a metallic rapping
noise.) " severe, this can
lead to engine darnage. " you detect heavy spark knock even ",hery using gasoline of the stated octane rating, 0<. if you hear steady spark knoo~ 'wfiil.)' Holding a' steady speed on level roads, have your
dealer correct the
problem . Failure to take steps to stop such knocking is
misuse
of the vehicle, for which Chevrolet is not responsible . However, now and then you may notice light spark knock for a short time while accelerating
or driving
up hills : This is no cause fo< concern, because you get the greatest
fuel economy
benem from the gasoline's octane rating when there is
occasional light spark knock. Using .gasoline with a higher .octane rating than
that which
allows occasional spark knock is an unnecessary expense.
Gasohol
Gasohol, a mixture of unleaded gasoline and ethanol (grain alcohol), is
available in some areas , You may use gasohol in yourvehicle ,provided it is no
more than 10% ethanoL Be sure the gasohol has octane ratings no lower than
those stated above for unleaded
gasoline . Some vehicles using gasohol could run leaner . Most drivers will not notice a difference, but some may. In such
cases your authorized dealer can make c.ertain adjustments, provided they are
not in violation of the Federal
Clean Air Act. " you. are still not satisfied with gaSOhol performance , you may prefer to uSe unleaded gasoline. •
NOTICE: ,Take care to not spiH gasohol on painted surfaces. Gasohol can cause paint damage, which may not be covered und~r the new vehicle warranty.

Downloaded from www.Manualslib.com manuals search engine Oil! Choke Indicator Light
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.
H the light remains on when engine is
running , have your Authorized Dealer locate and correct ' the trouble as soon as
possible .
Engine Temperature Indicator Light
This indicator light is providee .in the instrument cluster to. quickly warn of an
overheated engine. 'With the ignition in the START position, the ree TEMP
indicator (hot light) will light to
let you know that it is operating properly.
When the engine is starlee,
the ree light will go out immediately. tt will light up
at no other time unless for some
reason the engine reaches a dangerously
high operating temperature. Glance .at the instrument cluster freqtJentiyas you
drive, if this light is on see
"Engine Cooing System" on page 3,3.
Brake System Warning Light
The regular braking system is a dual system designee so that one part will
provide some braking action
n there is a loss of hydraulic pressure in the other
part of the system. The system has a "Brake" warning Ught Iocatee in the
instrument · panel.
• To serve as a reminder, the "6RAKE" light is designee to stay on when
the parking brake is not fully released and the ignition key is on.

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.
Windshield Wiper and Washer
The windshield wiping system operates at two speeds and is designed to wipe
clear
specijic areas of the windshield under most inclement weather conditions.
The windshield wipers work electrically and are not affected by engine
operation .
Push the control lever to the right to start
the electric windshield wiper. The
two-speed electric wiper has both a "low " and a "high " speed position .
