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
373 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
(Continued)
Caution (Continued)
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.
