Adding Washer Fluid
Your vehicle has a low washer fluid message that
comes on when the washer fluid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle. When the CHECK WASHER FLUID message is
displayed, you will need to add washer fluid to the
windshield washer fluid reservoir.
The windshield washer
fluid reservoir is located in
the engine compartment
toward the front of the
vehicle on the driver’s side.
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full.
Notice:
•
When using concentrated washer fluid, follow
the manufacturer’s instructions for adding
water.
•
Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts
of the washer system. Also, water does not
clean as well as washer fluid.
•
Fill your washer fluid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
•
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
Brakes
Brake Fluid
Your brake master cylinder reservoir is filled with DOT-3
brake fluid. See
Engine Compartment Overview on
page 5-10 for the location of the reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the
brake fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is
that fluid is leaking out of the brake system. If it is, you
should have your brake system fixed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.
