operating temperature. The power steering
fluid will be at the right temperature when
the engine coolant temperature gauge in the
instrument cluster is near the center of the
NORMAL operating temperature range.

[MC19000(MBC )01/96]
4. Check the fluid level on the dipstick (which
is highlighted in yellow in your vehicle). The
fluid level should be between the arrows in
the FULL HOT range, which is marked on
the side of the dipstick, opposite the side
marked FULL COLD. Do not add fluid if the
level is within the FULL HOT range.

4.6L SFI engine (check cold)
[MC20355(M )04/96]
NOTE: The brakes on the 4.6L engine vehicles
are powered by power steering fluid
from the power steering pump. The
fluid level in the power steering
reservoir will rise and fall due to the
amount of charge in the brake booster
accumulator. Therefore the following is
required.
[MC20400(MBC )12/95]
1. Check the fluid level when the system is
COLD (allow at least one half hour after
driving for the power steering fluid to cool).
[MC20500(MBC )04/96]
2. Locate the power steering reservoir mounted
to the front upper left-hand corner of the
engine.
[MC20550(M )04/96]
NOTE: Brake fluid and power steering fluid
CAN NOT be mixed. Only add brake
fluid to the brake master cylinder
reservoir. Only add power steering
fluid to the power steering reservoir.
[MC20600(MBC )12/95]
3. Visually verify that the fluid level is above
the MIN line adjacent to the reservoir ªsight
window.º
[MC20700(MBC )12/95]
4. If the power steering fluid is below the MIN
line, remove the cap and add fluid in small
amounts until the level is between the MIN
and MAX lines.
[MC20800(MBC )12/95]
5. Reinstall the reservoir cap.
[MC20850(M )03/96]
It is normal for the fluid level to be above the
MAX line after the brake pedal has been pushed
several times with the engine off. (If you want
to double check it; restart engine and turn
steering wheel to full right turn, then full left
turn and then turn engine off and re-check fluid
level. It should be between MIN and MAX line.)

Checking the Automatic Transmission
Fluid
*
[MC21600( ALL)01/96]
It is preferable to check the transmission fluid
level at normal operating temperature
150ÊF-170ÊF (66ÊC-77ÊC),after approximately 20
miles (30 km) of driving. However, if necessary,
you can check the fluid level without having to
drive 20 miles (30 km) to obtain a normal
operating temperature if outside temperatures
are above50ÊF (10ÊC).
[MC21700( ALL)12/95]
With the vehicle on a level surface, start the
engine and, while fully applying the brake
pedal, move the transmission shift selector
through all of the gear ranges allowing sufficient
time for each position to engage.Securely latch
the transmission shift selector in the P (Park)
position, fully set the parking brake and leave
the engine running.
[MC21900(MBC )12/95]
NOTE: Your vehicle should not be driven if
the fluid level is below the low cold
reading on the dipstick.
*
[MC22000( ALL)01/96]
Wipe off the dipstick cap, pull the dipstick out
and wipe the indicator end clean. Put the
dipstick back into the filler tube and make sure
it is fully seated. Pull the dipstick out and read
the fluid level.
[MC22100(MBC )12/95]
When checking fluid at normal operating
temperature150ÊF-170ÊF (66ÊC-77ÊC), thefluid
level should be within the hot notched area on
the dipstick. When the vehicle has not been
driven, and the fluid is at room temperature
50ÊF-95ÊF (10ÊC-35ÊC), thefluid level should be
within the cold notched area.

Because your vehicle's engine is electronically
controlled by a computer, some control
conditions are maintained by power from the
battery. If you ever disconnect the battery, install
a new battery, or experience a dead battery, you
must allow the computer to ªrelearnº its idle
conditions before your vehicle will idle at its
best. To let the engine do this, put the gearshift
in P (Park) (automatic transmission) or Neutral
(manual transmission), turn off all the
accessories, and start the vehicle. Let the engine
idle for at least one minute. (Engine must be
warm in order to ªlearn.º) Also, allow
approximately 10 miles (16 km) of stop and go
traffic for your vehicle's engine to completely
ªrelearnº its idle.

Wiper Blades
*
[MC24400( ALL)01/96]
Check the windshield wiper blades at least twice
a year. Also check them whenever they seem
less effective than usual. Substances such as tree
sap and some hot wax treatments used by
commercial car washes reduce the effectiveness
of wiper blades.

Emission Control System
*
[MC36600( ALL)01/96]
Your vehicle is equipped with a catalytic
converter which enables your vehicle to comply
with applicable exhaust emission requirements.
*
[MC36700( ALL)05/96]
RWARNING
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into
the passenger compartment. Under
extreme conditions excessive exhaust
temperatures could damage the fuel
system, the interior floor covering, or
other vehicle components, possibly
causing a fire.

[MC37600( ALL)01/96]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[MC37700( ALL)01/96]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
*
[MC37800( ALL)01/96]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
*
[MC37900( ALL)01/96]
By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device
or prevent it from working. In some of the
United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.
*
[MC38000( ALL)08/95]
Never use a metal exhaust collector when you
service your vehicle. If the metal collector
contacts any of your vehicle's plastic trim or
bumper parts they could melt or deform.
*
[MC38100( ALL)01/96]
Do not drive your vehicle if it does not operate
properly. See your dealer if the engine runs on
for more than five seconds after you shut it off
or if it misfires, surges, stalls, or backfires.
