SERVICING AND MAINTENANCE 433
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 interrupt the ignition when the transmission is ingear 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 when 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, discon -
nect 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.

Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used. Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis
-
sion Fluid (ATF) is an engineered product and its perfor -
mance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the transmis -
sion. The only exception to this policy is the use of special
dyes for diagnosing fluid leaks in six-speed transmissions.
Avoid using transmission sealers as they may adversely
affect seals.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate the brake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and (for six-speed transmissions) will require
more frequent fluid and filter changes. Refer to “Fluids
And Lubricants” in “Technical Specifications” for fluid
specifications.
