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.

Downloaded from www.Manualslib.com manuals search engine Federa1 regulations require that pumps delivering unleaded gasoline be labeled
with the word UNLEADED. Only these pumps have nozzles which fit the filler
neck of your vehicle 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 octa!1e (R) and Motor 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 octane rating as low as 85 in thes:e high-altitude areas:
Colorado , 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 staled above can cause persistent , heavy "spark knock." (''Spark knock" is a metallic rapping noise.) This
can lead to engine damage. If you detect heavy spark knock even when using
gasoline of the stated octane rating, or if you hear steady spark knock while
holding a steady speed on level roads, have your dealer correct the problem.
However. now and then you may
notice light spark knock for a short time while
accelerating or driving up hills. This is no cause for concern, because you get the
greatest
fuel economy benefit 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 unlead ed gasoline and ethanol (grain alcohol), is
available in some areas. You may use gasohol in your vehicle, provided it
is
no more than 10% ethanol. 'Be: sure the gasohol has the same octane
ratings as stated above for unleaded gasoline. If drivability problems are
encountered because _of the use of gasohol, you should switch back to
unleaded gas oline.
NOTICE: Take care to not spill gasohol on painted surfaces. Gasohol can cause paint damage, which may not be covered under the New Vehicle Warranty.
OPERATION IN FOREIGN COUNTRIES
Your engin~ is designed to run on unleaded gasoline with the octane ratings given
under '''Fuel Requirements" above .
If you plan to drive your vehicle outside the United States and its jurisdictions
or Canada, there is a chance the gasolines available in some count,ries will not meet the needs of your engine. Low octane rated gasolines may cause engine knocking
or serious engine damage,: for which Chevrolet is not respon sible .
Using leaded gasoline
in-a vehicle equipped with a catalytic converter may cause
the converter to lose its effectiveness as an emission control.
It could also affect
the emission warranty.
If you must use leaded gasoline in a vehicle designed for
unleaded fuel, converter modification and different maintenance intervals will be
required.
For gasoline information and a maintenance schedule for the countries
in which you plan to travel, write to: Chevrolet Motor Division, Consumer
Relations Department, Detroit, Michigan 48202, (in Canada , write to General
Motors of Canada Limited. Customer Service Department , Oshawa, Ontario LlJ
5Z6).
When writing, please include :
• the Vehicle Identification Number and
• the countries in which you plan to travel.

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.
