in a bassinet, preferably cove~ed and padded .- Pl ace il crossways in the car
(widthwise) on-the rear seat.
The bassi net should bi!.secure ly restrained with
the car's reg ular seat belt
s. Another method is to pla ce the bassinet so that
it rests aga,inst the back of the driver's seat, again crossways in the car.
2. Never let a child sta~d or kneel on any seat. Children who can sit up by
them selves should be placed on a seat and restrained with the seat belts
provided. When children ride in a rear se:at, they should be restrained with
a lap
belt. When children ride in the fronf seat, they . ,should wear both lap
and
shou'lder belt. If the shoulder bell irritates the neck or face due to th e
child's size, this may be reduced by placing the child closer to the center of the car. If irritation is not red uced, place the child in the rear seat.
3. General Motors advises that children should be restr ained properly when
riding . However, unusual'~conditions 'may prevent use of restraints, and
requir e that a small child,
sland. If that happens, the c hild should stand on
the floo r behind the driver's seat. This will help reduce the chance of being
hurt
by a frontal force impact in case of an accident.
TRAILER TOWING
This car is designed and intended to be used mainly to car ry people. Towing a
trailer will affect handling, durability and economy_ Your'"safcty and satisfaction
depend upon,proper use
of correct equipment. Also. you should avoid overloads
and other abusive use.
The maximum loaded trailer weight you can pull with your car depends
on what special equipment has-been inst alled o n it. We do-n o t recommend towing any
trailer more than 450
kilograms (1,000 pounds) -gross trailer weight unless your
'car ha s .he required equipment.
CAUTION: Do not try to tow any trailer more than 900 kilograms (2.000 pounds)
gross trailer weight (450 kilograms (' .000 pounds) for California emission equipped
cars with air conditioning) no matter what trailer towing equipment is installed. ;This ,could .eriously affect your car'S performance. durability or handling. which could
result in personel injury.
Infonnati on on trailer towing ability, special equipment requir ed, and optional
equipm e
nfavailable should be o~lained from your dea ler . (Ask for the trailering

When lowing trailers using a dead-weight hitch, inflate tires to the "Cold Tire
Pressure" for ·'Max . Load" show n on the Tire Placard on the left front door.
The allowable passenger and cargo load for this car,
also sh o wn on· the Tire
Placard, is reduced by the trailer tongue weight whenever the trailer is attached
t o the car.
Maintenance
More frequen.t servic e is requi red when using your car to pull a trailer. See Section
A of the Maint enance Schedule folder for Tran saxle Fluid and Engine Oil chang e
requirement~ for traitering.
Now and then. check that all trailer hitch bolts an d nuts are tight. Also see
"the Maintenance Schedule rol_def, and the Index in this manual , for important facts
o n
belts, coo ling system care and brake adjustment.
Break-In Schedule
See the new car break~in instru ctions in this manual. Also,. we recommend you
drive your new car for
500 mil es (800 kilometer s) before trailer tOwing. At the
" end
of this 500 mile (800 kilome te r) break-in period, avoid speeds over 50 mph (80 km/h) and full throttl e start s during the first 500 miles (800 kilometers) of
trailer towing.
If a new engine or transaxle is ins talled in you r car, observe the
same
care.
CAUTIONS:
Brakes -To help avoid personal injury due to poor braking action:
• Trailer brakes of adequate size are required on trailer s over 450 kilograms
(1,000 pounds) loaded weight.
• If you use trailer brakes with this car, follow the installation and balan ce
instructi ons
of the trailer brake maker.
• Do nol lap into the car's brake system if the trailer brake system uses more than 0.3 cubic centimeter (0.02 cubic inch) of nuid from the ca r's master
cylinder. In this case, the car's brake fluid capacity will not be enough to
operate
both the car and trailer brakes under all kind s, of use.
• All brak e fluid parts must be able to stand 20 685 kPa (3,000 psi). The brake
fluid tap must be made al th e upper rear master cylinder port. Copper tubing is subject to fatigue failure and must no t be used.
• Before going down a sleep or long grade , reduce speed and shift the tran saxle
into a lower gear to control your car's speed.
Try not to hold the brake pedal
down too long or too often. This could cause the brake s to get hot and not
work
as well.
Hitches -To help avoid personal injury due to sway caused by such things as
c rosswind
s, big trucks passing or road roughn ess, or due to sepa ration of the
trailer :
• Keep the trailer tongue load at 10% of the loaded trailer weight for
dead-w eight hitches. Tongue loads can be adjusted by proper distribution of the load in the trailer. This can be checked by weighing separately the loaded
trailer and then the tongue,
• When you remove a frailer hitch, be sure to seal any mountin g h'oles in the
body . This will help prevent entry of exhaust fumes, dirt or water. (See
"Engine Exhaust Gas Caution (Carbon Monoxide) " at the beginning of "Starting and Operating," Section 2 of this manual.)

Downloaded from www.Manualslib.com manuals search engine NOTICE: Use only trailer hitches which permit normal operation of the Energy Absorbing Bumper System. if so equipped. For example. a rigid fore and .iUt connection between the bumper and any other part.of. the car may increase .damage in the event of II collision.
TRAILER TOWING TIPS
Getting Started
Before entering traffic with a frailer that has electric brakes, start the car and
trailer moving and apply the trailer brakes
by hand to be sure the trailer brakes
are working and the trailer electrical system
is connected .
. Engine Cooling
:
When going up long grades, you, can reduce the chance 'of engine overheating by
turning
off the air conditioner, if so equipped.
Transaxle
,See the method for checking the transaxle fluid le ve l. in "Service and
,.;.Maintenance," Section 5 of this manual .
Parking
You should not park cars with trailers on a grade (hill). However, if you must
park on a grade, these steps must be followed:
1. Apply the regular brakes.
2. Have someone place wheel' chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load .
4; Apply Ihe parking brake.
S. Shift Ihe transaxle 10 ··P"(Park).
If the car is parked on a grade. don't shift the transaxle 10 "P"(Park) until the
trailer wheels
are chocked and the parkinghrake, is set~ If you do, the weight of . the car and trailer may put so much force on the parking pawl in the transaxle
.
that it may be hard to shift oul of "P"(Park).
When starting , after being parked ' on a grade:
(; Apply the regular brakes and hold.
2 .
Stan th e engine in ··P"(Park) .
-3. Shift into gear and release the parking brake.
4. Release the regular brakes and drive until the chock s are free.
5. Apply the regular brakes and have your helper remove the chocks.

• On cars with outside air vents in or under the instrument panel, open the vents fully.
New. Car "Break-In" Period
You can drive your new car from its very first mile/kilometer without following .
a
formal"break~in" schedule. However, there'are things you can do during the
fir st few hundred miles/kilometers of driving that will add to the future
perf orm ance and econ omy of your car.
We recommend you limit your speed during the first 500 miles (800 kiJomet ers) ~
to a maximum of 55 mph (90 km/h) ; but do not drive for long period s al any'
one constant speed, either Jast
or slow. During this time , avoid fulllhronJe start s _ and, if possible, avoid h"ard stops especially during the first 200 miles (320
kilometers) of driving.
Always drive at moderate speed until the engine has completely warmed
up.
If yo u plan to use your new car for trailer towing, see additional information in Section 1 under "Trailer Towing."
GUARD AGAINST THEFT
Your new Citation has many features to help prevent theft of the car itself, its
equ ipment, and its content s. But these ami-theft features depend upon you to
work .
THE TIME TO BE MOST ON GUARD IS WHEN LEAVING THE CAR ...
• PARK IN A LIGHTED SPOT WHEN YOU CAN.
• LOCK THE STEERING COLUMN AND TAKE THE KEYS,
•
Turn the key to "Lock," and remove the key. This locks the igniti on and
both steering and shift connols unless your car has a manual transaxle.
In that case, the shift control- is not locked .
• If you must leave a key with the car, leave the square-head key .only .
Take the oval-Read key with you. This will help prevent unwanted entry into your car at a later date, or into your -trunk.
•
FULLY CLOSE ALL WINDOWS AND ANY ROOF PANELS. AND LOCK ALL DOORS.
•
KEEP COSTLY ITEMS OUT OF SIGHT AND LOCKED UP,
•
Never leave things of value in plain sight on seats or noor.
• The glove box offers a place -to hide small items.
• Lock larger items in the trunk or place them in the rear storage .
FUEL REQUIREMENTS
Your engine is designed to use only unleaded gasoline. Unleaded gasoline must
be' used for the emission control $ystem to operate properly. Its use will also reduce
s park plug fouling , -exhaust system corrosion and engine oil deterionition .
Using leaded gasoline can damage the emiS5ion control system and could result
in loss of warranty coverage. This is especially true on cars that have the C-4
System . Leaded gasoline will damage tbe oxygen sensor, which may affect
emission control, fuel economy
and drivabiJity . See "C-4 (Computer Controlled
Catalytic Converter) System" in "Service and Maintenance" Section 5 of this
manual for more information.

STOWING THINGS IN (OR ON) THE CAR
CAUTION: luggage or other cergo should not be piled higher than the seatbacks, When at all possible, luggage or cargo should be C8rrifHj in the trunk area. The filler panel or cargo cover, between the rear 88atback and the rear window should not be used to carry objects-even those that are small and light. All nems should be secured in place. This will help keep such things from being thrown about and Injurying people in the car during an accident. Cargo weight whether inside or on the roof, should be positioned as evenly as possible from front to rear.
ROOF LUGGAGE CARRIER
The optional roof luggage carrier is designed to allow loading of items onto the
roof
of your car. The roof luggage carrier does not increase the total load carrying
capacity of th e car , as shown opposite "Max Load" on the Tire Placard located
on the left front door. Be sure the total weight of the cargo on the roof, plus the
weight
of the cargo and passe ngers inside the car, plus the tongue load of any
trailer you are towing does
,1;10t exc_eed this "Max Load" vehicle capacity weight. See Section 5, page "5-11 for more information on Vehicle Loading . Also see the
infonnation on Trailer Towing
in Section 1 of this manual . if needed .
NOTICE:To helpayoid pOSSible damage, do not exceed 70 kilograms (1 50 pounds), cargo weight on the roof. Position the cargo in the luggage carrier as evenly as: pOssible. If carrying long items, never exceed car length and fasten such loads securely at the front and rear of the car, as well as to the luggage rack.
The roof luggage carrier consists of: five roof slats bolted to the top of the car,
two crossrails with knobs at each end th~t allow the crossrails to be adjusted or removed, and six' adjustable tie-downs.
The operation
of each item is as follows: the crossrails are easily adjusted forward
or rearward in order to help position your load. To move the crossrails , rotate
the large adjustable knob, ··No. 3" in the figure above. counterclockwise to loosen
(or remove) the crossrails and 'clockwise to tighten down the cros srails. Attached
to the top
of the crossrails are two adjustable tie-downs, "No.4" in the figure.
Ther e is also one adjustable lie-down located in the center of each outer roof slat
assembly (also called
"No.4" in the figure) . The tie-downs may be easily moved
forward and rearward within the outer slat assembly and across the top
of the
crossrails to the desired position.
To move the tie-down . rotate it countetclockwise
to loosen and clockwise to tighten down. If needed to sec ure a certain type of lead,
the tie-downs on the
crossratls may be removed and repos itioned on the outer roof
slat assemblies. While underway, periodically check to make sure that
the crossrails and the tie-downs are securely fastened to help
prevent loss of cargo, or the roof rack equipment itself.
The crossrails may be removed when not in use and stowed in the trunk or behind
the second seat on the rear load floor (with the carg o cover installed) in hatchback
style

Your cooling system may temporarily overheat during severe operating
conditions, such as:
• climbing a long hilLon a hot qay,
•
stopping after high speed driving,
• idling for long periods' in' traffic, or
• towing a trailer.
If theUTEMP" light comes on (or if you have a coolant temperature gage, the

Downloaded from www.Manualslib.com manuals search engine On all C-4 cars, 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 emission control system
may be required. See your Chevrolet dealer' as soon as possible for an inspection of the system. Continued driving without having the C-4 System serviced _ could eventually
cause damage
to the emission control system . It could also affect fuel
e conomy and drivabili -ty.
ENGINE OIL AND FILTER RECOMMENDATIONS • Engine oils' are labeled on 'the containers with various API (American
Petroleum Institute) designations 6f quality. Use engine oils that are labeled
5E or SE/CC. Do not use oils labeled only SA, 5B, 5C, SD, CA, CB, CC or CD; _or oils with the combination label SE and CD (SE/CD). Higher
quality oils labeled SF will be introduced soon (late 1979, or 1980). These SF oils are preferred and should be used when available.
• The oil and filter change intervals for your engine are based on the use of SE-quality or SF-quality oils and ,high- quality filters such as AC oil filters. Using oils other than SE-quality or SF-quality oils, or oil change intervals
longer than recommended. could reduce -engine life and might affect your
warranty.
• Your engine was filled with a high·quality engine oil when it was built. You do ,not have to change this oil before the suggested change period.
•
If your normal driving does nQt include one or more of the four "severe service" conditions listed below. change the oil every 7,500 miles (12 000 ' kilometers) or 12 months, whichever comes first. Change the oillilter at the
first oil change. then every second oil change, if mileage (7,500 miles or 12
000. kilom~ters) determines .w ,hen you change the oil. If _time (12 months)
determines when you change the oil, change the filter with every oil change.
• Change the oil and oil filter every 3,000 miles (4 800 kilometers) , or three
months if you often drive under one or more of these 'severe service·,~.
conditions: • Driving in dusty areas
• Towing ,3 trailer
• Frequent idling or idling for long periods
• Driving 4 miles (6 kilometers) br'less in freezing weather,o~other short trips in cold weather, where the engine does not thoTough ,ly warm up.
• Change the oil and oil filter as soon as -possible after driving in a dust
storm.
Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel economy. Lowec viscosity
engine oils can provide increased , fuel " economy; however, higher temperature
weather conditions require higher viscosity engine oils for satisf~ctory lubrication.
To. get the best fuel economy with your-1980 Chevrolet, -iou should use -,, ' .
fuel. 'saviiJ.&:_engine oil ohhe_ proper viscosity. These oils call_ be found. in serviCe
stations and other retail stores. They are-identified by words such as: "Energy Saving," "Conserves Gasoline," "Gas Saving," "Gasoline Saving," '''Friction
Reducing," "Improved Gasoline Mileage" or "Fuel Saving."
The following chart lists the engine ' oil viscosities recommended for the
temperature range you expect before the next oil change. For lemperalures above ,_18°C (O"F),SAE lOW-30 is -the preferred viscosity grade. Ircold-weather starting
problems
are encountered at temperatures below -lSoC (

Page 66 of 95
Downloaded from www.Manualslib.com manuals search engine NOTICE: You cannot read the correct fluid level if you have just driven the car for a long time at high speed, in city traffic in hot weather, or if the car has been pulling a trailer. Wait. until the fluid has cooled down (about 30 minutes).
Remove the dipstick located on the driver's side forward of the cowl. Carefully
touch the wet end of the dipstick to find out if the fluid is cool, warm or hot. Wipe
it clean and push it back in until the cap seats. Pull
out the dipstick and read the
fluid level.
• If it felt cool or warm (about room temperature), the level should be
between the dimples above the "Full" mark.
• If it was too hot to hold. the level should be at or in the hatched area.
Add just enough DEXRON-®n fluid to fill the transaxle. It takes only 0.5 liter
(one pint)to raise the level from "Add" to "Full" with a hot transaxle.
Do not overfill the transaxle. Overfilling can cause foaming and loss of fluid, which
could result in transaxle damage.
Automatic Transaxle Drain Intervals
Change the transmission fluid and change the filter (or clean the screen) as
outlined in Section
A of the Maintenance Schedule folder.
ELECTRIC FAN
CAUTION: Keep hands, tools, and clothing away from the angine cooling fan to help prevent personal injury. This fan is electric and can come on whether or not the engine is running. The fan can start automatically in response to a heat sensor when the ignition is in the "Run" position.
ENGINE COOLING SYSTEM
The coolant recovery system is standard. The coolant in the radiator expands with
heat, and the overflow collects in the recovery tank. When the system cools down,
the coolant
is drawn back into the radiator.
The cooling system was filled at the factory with a quality coolant that meets
GM Specification 1899-M. The cooling system is designed to use coolant (a mixture
of water and ethylene glycol antifreeze) rather than plain water. The coolant
solution should be used year round. It has many advantages, such as:
• provides freezing protection down to _37°C, (-34°P)
•
provides boiling protection up to 128QC, (262°P)
•
protects against rust and corrosion in the cooling system,
• maintains the proper engine temperature for efficient operation and emission
control, and
• allows proper operation of the coolant temperature light (or gage).
See Section A of the Maintenance Schedule folder to find out when the coolant
must
be replaced.
COOLING SYSTEM CARE
Check the cooling system at regular intervals, such as during fuel stops. You
usually do not need to remove the radiator cap to check the coolant level. Lift
the engine hood and look at the "see through" coolant recovery tank. When the
engine
is cold, the coolant level -should be at or slightly above the "Full Cold"
mark on the tank. When the engine has fully warmed up, the level should be at ')r slightly below the "Full Hot" mark on the tank. If the coolant level is low,

NOTICE: Total combined weight of luggage compartment
load, luggage rack load (when-equipped) •. and passengers must not exceed the vehicle capacity weight (shown on the Tire Placard lOcated on the.left front door).
Inflation Pressure
The: cold inflation pressures listed on the Tire Placard provide for the best balance
of tire life, riding comfort. and vehicle handling under normal driving conditions.
If only one inflation pressure is recommended on the Tire Placard, this pressure
should be used for aU vehicle loading conditions. If your vehicle has two inflation
pressures listed on the placard, the "Max LDad" pressures can be used any time,
but must be used when you carry more passengers and cargo than is allowed in
the "Optional Pressures" section. The "Optional Pressures" can be used in lightly
loaded conditions by
'those who prefer the utmost in comfort. In all loading
conditions, use of the "Max Load" pressures will result in improved fuel economy.
Incorrect tire inflation pressures
can have adverse effects on tire life and_vehicle performance. Too Iowan" air pressure·"causes increased tire flexing and heat
build-up. This weakens the tire and increases the chance of damage or failure. It
can result in tire overloading, abnormal tire wear, adverse vehicle handling, and
reduced fuel mileage. 'I'oohigh
an air pressure can result in abnormal wear, harsh
ride, and also increase the chance of dar:nage from road hazards.
Tire inflation pressures should be checked (this includes the spare tire, unless it
is a stowaway spare) and whenever your vehicle is serviced. Always checJ<.,tire
inflation pressures when tires are "cold."
1. The "cold" tire inflation pressure applies to the tire pressure when a vehicle
has
not· been driven more than-one mile (1.6 kilometers) after sitting for three
hours or more.
2. It is normal for tire pressures to increase 30 to 60 kilopascals (4 to 8 pounds
per square inch)
or more when the tires become hot from driving. Do not "bleed" or reduce tire inflation pressures after driving your vehicle. Bleeding
reduces the
"cold" inflation pressure and increase tire flexing, which can
result in tire damage and failure.
3. FOr sustained driving at speeds of 75 mph to 85 mph (120 km/h to 140 km/h),in countries where such speeds are permitted by law, cold
inflation pressures must be increased
30 kPa (4 psi) above the cold inflation
pressures stated on the Tire Placard up to the maximum for each load
range stated in
the_ chart below.
Sustained speeds of 75 mph to 85 mph (120 km/h to 140 km/h) ARE
NOT ADVISED when the 30 kPa (4 psi) adjustment would require pressures greater than the maximum for each load range stated on the chart. Sustained
driving at speeds over 85 mph (140 km/h), where permitted by law. IS NOT ADVISED unless your vehicle is equipped with special high speed tires
available from many tire dealers.
