electronic,
closed- loop, high energy spark control system that permits the use
of today's compression ratios with unleaded fuels. It works to control spark and
provide
good driveability. H automatically compensates for fuel octane,
atmospheric conditions,
load, and .other driving conditions, by continually monitoring engine detonation and adjusting the spark.
Are There Any Tricks To Driving A Turbocharged V-61
No, riot at all. Starting procedures are as covered on Page 2-8.
As with any normal engine, the turbocharged engine should not be run at
excessive
RPM immediately upon starting or shut down abruptly after running
at high
speeds.
Trailer
Towing: It should be noted that the Turbo V-6 engine uses advanced
electronic technology to provide a combination of performance and fuel
economy under most operating conditions, including driving in high-altitude
areas . Uke 'most V-6 engines, ~is su~abIe for pul~ng light-dutytrailers up to
450 kilograms (1,000 pounds) gross weight. However, the system was not
engineered for the rigors of towing
heavytraii for
specffic recommendations) .
Don't Attempt Do-tt-Yourself Fixes: The turbocharger has but a handful of
parts, but since it is precision-manufactured with some tolerances as fine as
1/1 ,000,000 of an inch, maintenance and repairs should be done by an
authorized Chevrolet dealer or other qualified service outlet which
regularly
does such servk:e.
Catch Trouble Before . It Becomes Major: The turbocharger is an integral part
of your engine and not ar\'add-on .device.1f you spot an oil leak or hear an
unusual sound coming from the turbocharger , take it
In for service immediately .
The trouble may be simple to correct, but if allowed to continue, may
necessitate a more costly repair.
Normaf Scheduled Maintenance -
with Two Exceptions: The recommended
maintenance for the turbocharged
V -6 engine is shown in the General Motors
Maintenance
Schedule found in the glove compartment of your Chevrolet. The
turbocharged engine requires basically the same maintenance as a regular V-6
with two ",xceptions :
Engine Oil Change -every 3,000 miles.
Oil Filter Change -every 3,000 miles .

Corrosion Protection
Generally, your vehicle has been designed and built to resist corrosion . Special
materials and protective finishes were used on most parts of your vehicle when it was built to help maintain good looks, strength and reliable operation .
However , some parts which normally are not visible (s uch as c ertain parts
under the the
hood ) are such that surface rust will not affect their reliability .
Therefore, corrosion protection i's not needed or used on these parts.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replac .ement ,
make
sure IheboOY .[epair S \)gJ;l) ll)Plies anti-corrosion material to the part s
repaired or replaced so that corrosibn '''protection is restored. (Also see "Finish
Damage" which follows .)
Foreign Material Deposits
Calcium chloride and other salts, ice melting agents, road oil and tar, tree sap,
bird droppings, chemicals. from industrial chimneys, and other foreign matter
may damage vehicle finishes
if left on painted surfaces.
Prompt washing
may not completely remove all of these depOSits. Other
cleaners
may be needed . When using chemical cleaners developed for this
purpose , be sure they are safe 'for use on painted surfaces .
FiniSh Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
promptly . Exposed metal will co rrode quickly and may develop into major repair
,expense.
Minor chips and scratches .can be repaired with tQuch-up materials available
from your Chevrolet dealer
or other service outlets . Larger areas of finish
damage can
be corrected in your dealer's body and paint shop.

CATALYTIC CONVERTER
.Ttle .cal;!ly:tic 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 catalysts , unleaded gasol;"" must be used . Unleaded gasoline also
reduces spark plug louling. exhaust system corrosion and engine oil
deterioration.
The catalytiC converter requires the use of unleaded gasoline. Using leaded gasoline wilt cause --the converter to lose its effectiveness as an
emission control device. Leaded gasoline will also damage the Computer
Command Control, system oxygen sensor, which could affect emission control,
fuel economy . and drivability.
~,~.,y..'~,","~ ... :..., To help 'prevent damage:
1. Keep your engine properly maintained . Engine malfunctions involving the electrical, carburetion or ignition systems may result in unusually high
catalytic con verter and exhaust . sy~tem temperatures which, under
extreme malfunctioning conditions·, may ignite interior floor:"'covering
materials above the converter. Do not keep driving your vehicle if you
detect engine misfire, noticeable loss of performance ,or other unusual operating conditions. Instead. have it serviced promptly.
A properly maintained
engine will help avoid malfunctions that could damage
the converter.
~ will also help provide good emission control and fuel economy.
See the Maintenance Schedule , folder for information on inspecling and
maintaining the engine. exhaust system. and other components. .
2. Do not drive through or Idle or park your vehicle over combustible
materials, such as grass or leaves_ They could touch the hot exhaust
system and ignite.
3. Do not push or tow this vehiCle to start it. This may result in unusually
high catalytic converter and exhaust system temperatures which under
extreme conditions may ignite interior floor -covering material above the
converter.
Pushing or towing to start can also damage · the catalytic
converter itself.
Disregarding these
instructions could damage the cataly:tic converter. the
vehicle, or nearby property.
