Refill the reservoir more frequently when
driving conditions require an increased
amount of window washer fluid.

Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Antifreeze or equivalent.

CAUTION

.

Do not substitute engine anti-freeze
coolant for window washer solution. This
may result in damage to the paint.

.

Do not fill the window washer reservoir
tank with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the window washer reser-
voir tank.

.

your hands. If the acid contacts your
eyes, skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.

.

Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.

.

When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.

.

Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.

.
