Washer Fluid

What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an area
where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full. See Engine Compartment
Overview 0 284 for reservoir location.
Caution
Do not use washer fluid that
contains any type of water
repellent coating. This can cause
the wiper blades to chatter
or skip.
Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system and
paint.
Do not mix water with
ready-to-use washer fluid. Water
can cause the solution to freeze
and damage the washer fluid
tank and other parts of the
washer system.
When using concentrated washer
fluid, follow the manufacturer
instructions for adding water.
Fill the washer fluid tank only
three-quarters full when it is very
cold. This allows for fluid

expansion if freezing occurs,
which could damage the tank if
it is completely full.

Brakes

Disc brake linings, except J57 V-Series
Blackwing with carbon ceramic brakes,
have built-in wear indicators that
make a high-pitched warning sound
when the brake linings are worn and
new linings are needed. The sound
can come and go or can be heard all
the time when the vehicle is moving,
except when applying the brake pedal
firmly. The V-Series Blackwing has
electronic pad wear sensors. See Brake
Pad Life System (If Equipped) 0 304
Warning
The brake wear warning sound
means that soon the brakes will not
work well. That could lead to a
crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
