Front Windshield Washers
ONX4050044ONX4050044
In the OFF position, pull the lever gently
toward you to spray washer fluid on the
windshield and to run the wipers 1-3
cycles. The spray and wiper operation
will continue until you release the lever. If
the washer does not work, you may need
to add washer fluid to the washer fluid
reservoir.
Recirculating air when washer fluid
is used
When washer fluid is used, in order to
reduce any unpleasant scent of the
washer fluid from entering the cabin,
recirculation mode and air conditioning
are automatically activated depending
on the outside temperature. If you
select fresh mode while the function is
operating, the function will resume after
a certain amount of time. It may not work
in some conditions such as cold weather
or engine OFF.
For more details, refer to “Climate
Control Additional Features” section in
this chapter.
WARNING
When the outside temperature is below
freezing, ALWAYS warm the windshield
using the defroster to help prevent
the washer fluid from freezing on the
windshield and obscuring your vision
which could result in an accident and
serious injury or death.
NOTICE
• To prevent possible damage to the
washer pump, do not operate the
washer when the fluid reservoir is
empty.
• To prevent possible damage to the
wipers or windshield, do not operate
the wipers when the windshield is
dry.
• To prevent damage to the wiper
arms and other components, do
not attempt to move the wipers
manually.
• To prevent possible damage to the
wipers and washer system, use anti-
freezing washer fluids in the winter
season or cold weather.

Maintenance9-6
While operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine coolant reservoir.
• Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year:
• Check radiator, heater and air conditioning hoses for leaks or
damage.
• Check windshield washer spray and wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlight alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate automatic transmission linkage and controls.
• Clean the battery and terminals. (For plug-in hybrid vehicle)
• Check the brake fluid level.

3. Lift up the wiper blade, and pull it out.
ONX4E090052ONX4E090052
4. Install the new blade assembly by inserting the center part into the slot
in the wiper arm until it clicks into
place.
If the replacement is complete, put
down the wiper arm to place it on
the rear windshield, and turn the
vehicle ignition to ON and operate the
wipers to check the blade is installed
correctly.
5. Make sure the blade assembly is installed firmly by trying to pull it
slightly.
To prevent damage to the wiper arms or
other components, Have the wiper blade
replaced by an authorized HYUNDAI
dealer.
CAUTION
If the wiper arm receives too much
force while pulling the blade, the center
part may be damaged.
CAUTION
• The wiper could not operate for
approx. 10 seconds when the wiper
is operated without washer fluid or
the blades are frozen. This is not a
malfunction, it is a wiper protection
system activated by motor overload
circuit within the wiper motor.
• The front windshield should be
cleaned with water hose and wiped
with clean towel with wiper blades
raised up. Also, the wiper blades
should be wiped clean when the
grease or wax is applied to the
blades.
