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

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.

damage the air flow sensor.

ing procedure, and be careful to
avoid damaging other components.

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.

the battery when the vehicle’s
battery cables are connected
to the battery.
The electrical ignition system
works with high voltage.
NEVER touch these compo-

Batteries contain sul-
phuric 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 imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical 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.
