1. Start the engine and let it run until the
power steering fluid reaches normal
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.

[MC18800( ALL)01/96]
2. While the engine idles, turn the steering
wheel back and forth several times. Make
sure that the cap assembly is installed at this
time.

[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.
*
[MC19200(MBC )01/96]
5. If the power steering fluid is low, add fluid
in small amounts, continuously checking the
level, until you reach the FULL HOT range.
Do not overfill.
*
[MC19400(MBC )03/96]
6. When you are finished, put the dipstick back
in and make sure that it fits snugly.

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).

Automatic Transmission Fluid
*
[MC21400( ALL)03/96]
Under normal circumstances, you do not need to
check the fluid level of the transmission, since
your vehicle does not use up transmission fluid.
Refer to theMaintenance Schedulebooklet for
replacement intervals. However, if the
transmission is not working properly Ð for
instance, the transmission may slip or shift
slowly, or you may notice some sign of fluid
leakage Ð the fluid level should be checked.

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.

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 or
install a new battery, you must allow the
computer to ªrelearnº its idle conditions before
your vehicle will drive properly. To let the
engine do this, put the gearshift in P (Park), 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

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.

Your vehicle was not designed to use fuel
containing manganese-based additives such as
MMT. Additionally, vehicles certified to
California emission standards (indicated on the
underhood Vehicle Emissions Control
Information label) are designed to operate on
California reformulated gasolines. If California
reformulated gasoline is not available when you
refuel, your vehicle can be operated on
non-California fuels. However, even though your
engine will perform adequately on other
gasolines, the performance of the emission
control devices and systems may be adversely
affected. Repair of damage caused by using a
fuel that your vehicle was not designed for may
not be covered by your warranty.

[MC33400( ALL)12/95]Calculating Fuel Economy
*
[MC33500( ALL)01/96]
Fuel economy is an estimate of the efficiency of
your vehicle, and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
*
[MC33600( ALL)01/96]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[MC33700( ALL)01/96]
To calculate fuel economy:
*
[MC33800( ALL)01/96]
1. Fill the fuel tank completely and record the
initial odometer reading.
*
[MC33900( ALL)01/96]
2. Every time you buy fuel, record the
amount (in gallons or liters) purchased.
*
[MC34000( ALL)01/96]
3. After at least 3-5 tankfuls, fill the fuel tank
and record the final odometer reading.

EPA fuel economy figures are obtained from
laboratory tests under simulated road conditions
and may not reflect the actual conditions you
experience or your style of driving. The EPA
fuel economy estimate is not a guarantee that
you will achieve the fuel economy shown.
