Washer Fluid
▼Inspecting Washer Fluid Level
WARNING
Use only windshield washer
fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
a ff ect your visibility, and could result in
an accident.
Using Washer Fluid Without
Anti-freeze Protection in Cold
Weather:
Operating your vehicle in temperatures
below 4 °C (40 °F) using washer fluid
without anti-freeze protection is
dangerous as it could cause impaired
windshield vision and result in an
accident. In cold weather, always use
washer fluid with anti-freeze
protection.
NOTE
State or local regulations may restrict
the use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides
adequate freeze resistance for all
regions and climates in which the
vehicle will be operated.
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
The top of the float should be between
F and E.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold
weather to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.

Body Lubrication
▼Body Lubrication
All moving points of the body, such as
door and hood hinges and locks,
should be lubricated each time the
engine oil is changed. Use a
nonfreezing lubricant on locks during
cold weather.

Make sure the hood's secondary latch
keeps the hood from opening when
the primary latch is released.

Hot waxes applied by automatic car
washers have been known to
aff ect
the wiper's ability to clean windows.

blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
 When the wiper lever is in the AUTO
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
 If the windshield above the rain
sensor is touched.
 If the windshield above the rain
sensor is wiped with a cloth.
 If the windshield is struck with a

Battery
▼Battery
WARNING
Wash hands after handling the battery
and related accessories:
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the
State of California to cause cancer and
reproductive harm.
Read the following precautions
carefully before using the battery or
inspecting to ensure safe and correct
handling:
Always wear eye protection
when working near the battery:
Working without eye protection is
dangerous. Battery fluid contains
SULFURIC ACID which could cause
blindness if splashed into your eyes.
Also, hydrogen gas produced during
normal battery operation, could ignite
and cause the battery to explode.
Wear eye protection and
protective gloves to prevent contact
with battery fluid:
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID
which could cause serious injuries if it
gets in eyes, or on the skin or clothing.
If this happens, immediately flush your
eyes with water for 15 minutes or wash
your skin thoroughly and get medical
attention.
Always keep batteries out of
the reach of children:
Allowing children to play near batteries
is dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or
on the skin.
Keep flames and sparks away
from open battery cells and do not
allow metal tools to contact the
positive (+) or negative (-) terminal of
the battery when working near a
battery. Do not allow the positive (+)
terminal to contact the vehicle body:
Flames and sparks near open battery
cells are dangerous. Hydrogen gas,
produced during normal battery
operation, could ignite and cause the
battery to explode. An exploding
battery can cause serious burns and
injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
