Engine oil level
Check
the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 413 for
additional information.
Power steering fluid level
Check the level on the dipstick. The level should be in
the ºHOTº or ºCOLDº range depending on the fluid
temperature. See page 428 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or
smell exhaust fumes, have the cause located and
corrected immediately. (See engine exhaust cautions in
Section 3±1.)
DOES YOUR VEHICLE NEED REPAIRING?
Be on the alert for changes in performance and sounds,
and visual tip±offs that indicate service is needed. Some
important clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water
dripping from the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a
dangerous carbon monoxide leak. Drive with the
windows open and have the exhaust system checked
immediately.)

Flat±looking tires, excessive tire squeal when
cornering, uneven tire wear

Vehicle pulls to one side when driving straight on a
level road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake
pedal, pedal almost touches floors, vehicle pulls to
one side when braking

Engine coolant temperature continually higher than
normal

CAUTION

When the engine is running, keep hands, clothing,
and tools away from the moving fan and engine drive
belt. (Removing rings, watches, and ties is
advisable.)

Right after driving, the engine compartment ± the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. ± will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.

Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.

Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or
other solid supports.

Be sure the ignition is off if you work near the electric
cooling fan or radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if
the air conditioning is on and/or if the coolant
temperature is high.

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
