CAUTION!
•
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will destroy
the effectiveness of the catalyst as an emissions
control device and may seriously reduce engine
performance and cause serious damage to the
engine.
•
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Con-
tinued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is
important to keep the engine properly tuned to ensure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control systems
can result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool. Ser-
vice, including a tune-up to manufacturer's specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•
Do not interrupt the ignition when the transmission
is in gear and the vehicle is in motion.
•
Do not try to start the vehicle by pushing or towing
the vehicle.
•
Do not idle the engine with any ignition components
disconnected or removed, such as during diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
COOLING SYSTEM
WARNING!
•
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never open a cooling system
pressure cap when the radiator or coolant bottle is
hot.
•
Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised.
The fan starts automatically and may start at any
time, whether the engine is running or not.
•
When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition to
the OFF mode. The fan is temperature controlled
and can start at any time the ignition is in the ON
mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant is dirty or rusty in
appearance, the system should be drained, flushed and
refilled with fresh coolant. Check the front of the A/C
condenser or radiator for any accumulation of bugs,
leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the A/C con-
denser or the back of the radiator core.
Check the engine cooling system hoses for brittle rub-
ber, cracking, tears, cuts and tightness of the connec-
tion at the coolant recovery bottle and radiator. Inspect
the entire system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN
THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant prop-
erly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed
to be added to the system please contact an authorized
dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with Organic Additive Technology (OAT) coolant
(conforming to MS.90032).
Refer to the “Service And Warranty Handbook (Auto
Biography)” for the proper maintenance intervals.
