• 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.

"EMISSIONS" INDICATOR
On so me cars, the word "EMISSIONS" is des ig ned to appear in a window in the spe ed om eter faceat certain int~rvals. This is a reminder that maintenan ce se rv ice
mu st
be performed on your ca r. One of two type s' o f se rvice is required :
• On cars equipped with the C-4 System, the oxygen sensor must be replaced with · a new sensor, or
• On
ca rs without the C -4 System, the cataly st in the catalyti c converter must
b e c han ged.
In either case, see yo ur Chl!~rolet dealer fo r se rvice when the "EMISSIONS "
indicat or appears. .
F or more information , see
"C-4 (Computer Contr olled Catalytic Conv erte r)
Syste m " and "Catalyti c Co nverter," both in "Service and Maintenance," Section
5 of thi s manual.
"CHECK ENGINE" LIGHT
If yo ur car has the C-4 System, a "CHECK ENGINE" light on the instrum ent
panel is des ig ned t o come on
during engine starting to le t y ou know th e bulb is
w orkin g. (The light will sla y o n a short time after th e e ngine s tarts .) If th e light

Downloaded from www.Manualslib.com manuals search engine CATALYTIC CONVERTER
. The catalytic converter is an emission control device added to the
exhaust system to reduce exhaust gas pollutants. The converter
contains a ceramic material coated with noble metal catalysts. To prevent
contamination of the cata lysts,
unle~ded gasoline must be used. Unleaded gasoline
also reduc es combustion chamber deposits and exhaust system corrosion.
The catalytic converter requires the use of unleaded gasoline. Use
of leaded gasoline will cause the converter to lose its effectiveness for emission control. On some engines, the catalyst must be changed at cer tain inter vals in orde r for
the emissio n control system to continue to operat e properly. The change intervals
are speci fied in Section C of the Maintenance Schedule folder.
On cars that require this catalyst change, the word "EMISSION" will
appear on an indicator in the speedometer face at the specified change
in terval
s. This is a reminder that the cata lyst must be changed. (If the indicator does not appear, your car does not need this catalyst change).
Your Chevrolet deale r will perform the lirst cataly st cha nge at no charge, whether yO'u are the first owner or a subsequent owner. As part of this service, the indicator
should be reset to appear
at the next specified chang e interval. To help prevent
damage:
1. Keep your engine properly maintained. Engine malfunctions involving th e electrical, carburetion or ignition systems may result in unusually high
conve rter and exhaust system temperatures .
Do not keep driving your vehicle if you detect engine misfire. noticeable loss of
perform,8nce. or other unusual operating conditions. Instead, have it serviced promptly. A properly ···maintained engine will he lp avoid
malfunction s that could damage the converter.
It will also help provide good
emissio.n cq!).,trol and gasoline economy. See the Maintenance Schedule folder
for inform ation on inspecting a
nd maintaining the engi ne. exhaust system.
and other compone nts.
2 .
Do not drive through, idle, or park your vehicle over combustibl e materials,
s u ch as grass
or leaves. They could 'touch the hot exhaust system and ignite.
3. Do n o t push or tow this vehicle 10 stan it. This cou ld damage (he converter.
Disregarding this information could damage the catalytic converter, the vehicle,
or nearby property.
C-4 (COMPUTER CONTROLLED CATALYTIC CONVERTER)
SYSTEM If your new car was purchased in California, it has a special emission control
system, called
the C-4 (Computer Co ntrolled Catalytic Converter) System. The C4 System monitors the exhaust stream with an oxygen sensor. Based 4
on senso r signals, the electr onic control module adjusts the carburetor
air~fuel ratio as needed. It is very important to use only unleaded gasoline
in cars with
the C-4 System. Leaded gasoline will damage the oxygen
sensor. which may affect emission
control, fuel economy and drivability.
Some cars equipped with the C-4 System need an oxygen sensOr change
at the intervals specified in Section C of the Maintenance Schedule folder.
On these cars, an oxyge n sensor maintenance reminder is included in the
instrument paneL The word "EMISSIONS" is designed to appear in a
window in the speedometer face at the intervals outlined in the Maintenance
Schedule folder. The "EMISSIONS " indicator is a reminder that the oxygen
sensor must be repl aced with a new sensor.
Such replacement is necessary
in order to maintain the correct operation of the emiss ion control system.
The indicator must be reset as part of this service.

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,
