Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir.

Because your vehicle
’s engine is
electronically-controlled by a computer,
some engine control settings are
maintained by power from the low voltage
battery. Some engine computer settings,
like the idle trim and fuel trim strategy,
optimize the driveability and performance
of the engine. Some other computer
settings, like the clock and radio station
presets, are also maintained in memory by
power from the low voltage battery. When
a technician disconnects and connects the
low voltage battery, these settings are
erased. Complete the following procedure
in order to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift the transmission into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and start the vehicle.
5. Run the engine until it reaches normal operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 357). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 82).
Reset the radio station presets. See
Audio System
(page 357).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
7. While the engine is running, press the brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
to completely relearn the idle and fuel
trim strategy. Note:
If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
CHECKING THE WIPER
BLADES Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
The wiper arms can be manually moved
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.

a flat zone of high intensity light
located at the top of the right hand

headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the
horizontal reference line.
6. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
