WASHER FLUID
Checking the Washer Fluid Level
ONX4H090010ONX4H090010
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used during summer
months if washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold climates
to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.
• Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from
children and animals.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE
• Do not allow brake fluid to contact
the vehicle’s body paint, as it will
result in paint damage.
• NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed.
• Do not use the wrong type of brake
fluid. A few drops of mineral based
oil, such as engine oil in your brake
system can damage brake system
parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
