Checking the Brake Fluid Level
ODN8089005
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified brake
fluid to the MAX level. The level will fall
with accumulated mileage. This is a
normal condition associated with the
wear of the brake linings. If the fluid level
is excessively low, have the brake system
checked by an authorized HYUNDAI
dealer.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake fluid
comes in contact with 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 paint
damage will result.
• Brake fluid, which has been exposed
to open air for an extended time
should NEVER be used as its quality
cannot be guaranteed. It should be
disposed of properly.
• Do not use the wrong kind 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” in chapter 2).

Checking the Washer Fluid Level
ODN8089006
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used 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 flames 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.

Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE
• Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.
• When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.
• Use HYUNDAI genuine parts. Use of
non-genuine parts could damage the
air flow sensor.

wipEr BladES
Blade Inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wiper functionality. Common
sources of contamination are insects,
tree sap, and hot wax treatments used
by some commercial car washes. If the
blades are not wiping properly, clean
both the window and the blades with a
clean cloth dampened with washer fluid.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not:
• Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
• Attempt to move the wipers
manually.
• Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE
• In order to prevent damage to the
hood and the wiper arms, the wiper
arms should only be lifted when in
the top wiping position.
• Always return the wiper arms to the
windshield before driving.
NOTICE
The use of a non-specified wiper blade
could result in wiper malfunction and
failure.

WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present
in battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric acid
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
• The electrical ignition system works
with high voltage. NEVER touch
these components with the engine
running or when the ignition switch
is in the ON position.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to the
State of California to cause cancer,
birth defects and reproductive harm.
Batteries also contain other chemicals
known to the State of California
to cause cancer. Wash hands after
handling.
NOTICE
• When you do not use the vehicle for a
long time in a low temperature area,
disconnect the battery and keep it
indoors.
• Always charge the battery fully to
prevent battery case damage in low
temperature areas.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment
near the battery.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
immediately consult an authorized
HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit you may not need for
operating the vehicle.
If the headlamps or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
