Checking the brake/clutch
fluid level
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulat-
ed kilometres. This is a normal condi-
tion associated with the wear of the
brake linings.If the fluid level is excessively low,
we recommend that the system be
checked by an authorised HYUNDAI
dealer.
Information
Use only the specified brake/clutch
fluid. Refer to Recommended lubri-
cants and capacities in chapter 8.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap (if
equipped).
Information
Clean the filler cap before removing.
Use only DOT3 or DOT4 brake/clutch
fluid from a sealed container. Do not allow brake/clutch fluid
to contact the vehicle's body
paint, as paint damage will
result.
Brake/clutch 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 dis-
posed of properly.
Don't put in the wrong kind of
fluid. A few drops of mineral-
based oil, such as engine oil, in
your brake/clutch system can
damage system parts.
NOTICE

OPD077016R
If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. We
recommend that the vehicle be
inspected by an authorised
HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention.

Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard whilst 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 serviced by an autho-
rised HYUNDAI dealer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).OPD077017L

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 wind-
screen 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 flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.

Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and pre-
venting accumulating of water in the
base.
When enough water has accumulat-
ed inside the fuel filter, the warning
light ( ) illuminates with the igni-
tion switch in the ON position.
In this case, we recommend you to
have the system checked by an
authorised HYUNDAI dealer.
When the accumulated water is not
drained at the proper timing, water
may permeate in the fuel filter,
damaging the major vehicle com-
ponents, such as the fuel system.
Fuel filter cartridge replace-
ment
We recommend the fuel filter car-
tridge be replaced by an authorised
HYUNDAI dealer according to the
Maintenance Schedule at the begin-
ning of this chapter.
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.NOTICE

Maintenance
1. Loosen the air cleaner cover
attaching clips and open the cover.
2. Wipe the inside of the air cleaner.
3. Replace the air cleaner filter.4. Lock the cover with the cover
attaching clips.
5. Check that the cover is firmly
installed.
Information
Be sure to insert the hinge (A) before
locking the cover with the cover
attaching clips.
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 chap-
ter).
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.

air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and
replaced earlier. When you, the
owner, replace the climate control air
filter, replace it performing the follow-
ing procedure, and be careful to
avoid damaging other components.
Replace the filter according to the
Maintenance Schedule.
Filter replacement

5. Replace the climate control air filter.
6. Reassemble in the reverse order
of disassembly.
Install a new climate control air filter
in the correct direction with the
arrow symbol (
↓ ↓) facing down-
wards, otherwise, it may be noisy
and the effectiveness of the filter
may be reduced.
Blade inspection
Contamination of either the wind-
screen or the wiper blades with for-
eign matter can reduce the effective-
ness of the windscreen wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
Use petrol, kerosene, paint thin-
ner, 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 windscreen diffi-
cult to clean.
Information
Wiper blades are a consumable item.
Normal wear of the wipers may not be
covered by your vehicle warranty.

Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.

To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manu-
ally.
In order to prevent damage to
the hood and the wiper arms, the
wiper arms should only be lifted
when in the fully up position.
Always return the wiper arms to
the windshield before starting
your journey.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.
Front windscreen wiper blade
This vehicle has a "hidden" wiper
design which means that the wipers
cannot be lifted when they are in their
bottom resting position.
1. Within 20 seconds of turning off the
engine, lift and hold the wiper lever
up to the MIST position for about 2
seconds until the wipers move to
the top wipe position.
2. At this time you can lift the wipers
off the windscreen.
3. Gently put the wipers back down
onto the windscreen.
4. Turn the wipers to any ON position
to return the wipers to the bottom
resting position.
Type A
1. Raise the wiper arm and turn the
wiper blade assembly to expose
the plastic locking clip.
