Checking the washer fluid level
OBI3090038OBI3090038
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
Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control or damage to the
paint and body trim.
• Windshield washer fluid agents
contain some amounts of alcohol
and can be flammable under certain
circumstances. Do not allow sparks
or flame come in contact with the
washer fluid or the washer fluid
reservoir. Damage to the vehicle or
occupants could occur.
• Windshield washer fluid is poisonous
to humans and animals. Do not drink
and avoid coming in contact with
the windshield washer fluid. Serious
injury or death could occur.

Checking the parking brake
OAI3069006OAI3069006
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
while fully applying it from the released
position.
Also, the parking brake alone should
securely hold the vehicle on a fairly
steep grade. If the stroke is more or less
than specified, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.
Stroke : 5~7 “clicks’’ at a force of 20 kg
(44 lbs, 196 N).

Maintenance
Draining water from fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in its
bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position.
If this warning light turned
on, we recommend that the
system be serviced by an
authorized HYUNDAI dealer.
NOTICE
If the water accumulated in the fuel
filter is not drained at proper times,
damages to the major parts such as the
fuel system can be caused by water
permeation in the fuel filter.
Fuel filter cartridge replacement

Blade inspection
1JBA51221JBA5122
i Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers. 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 good
cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
do not use petrol, kerosene, paint
thinner, or other solvents on or near
them.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE
To prevent damage to the wiper arms
or other components, do not attempt
to move the wipers manually.
NOTICE
The use of a non-specified wiper blade
could result in wiper malfunction and
failure.
