262SERVICING AND MAINTENANCE
(Continued)
Under normal operating conditions, the
catalytic converter 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. Service,
including a tune-up to manufacturer's
specifications, should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the
ignition when the transmission is in gear and
the vehicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
NOTE:
The vehicle exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system,
if the exhaust system is replaced with after -
market products a Malfunction Indicator Lamp
(MIL) will illuminate.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If coolant is dirty or
rusty in appearance, the system should be
drained, flushed, and refilled with fresh coolant.
Check the front of the 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 condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
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 automati -
cally and may start at any time, whether the
engine is running or not.
When working near the radiator cooling fan,
disconnect 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.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability Safety
Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling
of sluggish response or over responsiveness in
the steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Overinflation produces a
jarring and uncomfortable ride.
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stopping
distance. Use tires of the recommended load
capacity for your vehicle. Never overload
them.WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle
to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
