7EXPLANATION OF SCHEDULED MAINTENANCE ITEMSEngine oil and filterThe engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.Drive beltsInspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
Fuel filter (cartridge)A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. We recommend that
the fuel filter be replaced by a HYUNDAI
authorised repairer.
Fuel lines, fuel hoses and con-
nectionsCheck the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connections be replaced by a
HYUNDAI authorised repairer.
WARNING -
Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectors
and high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.
CAUTION
When you are inspecting the belt,
place the ignition switch in theLOCK/OFF or ACC position.

Maintenance
Vapour hose and fuel filler capThe vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuel
filler cap is correctly replaced.Vacuum crankcase ventilation
hoses (if equipped)Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filterWe recommend that you use air cleaner
filter for replacement from a HYUNDAI
authorised repairer.Spark plugs (for petrol engine)Make sure to install new spark plugs of
the correct heat range.Cooling systemCheck the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.CoolantThe coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)Inspect the manual transaxle fluid
according to the maintenance schedule.Automatic transaxle fluid
(if equipped)Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, we recommend
that the fluid be changed by a HYUNDAI
authorised repairer in accordance to the
scheduled maintenance at the beginning
of this chapter.✽ ✽NOTICEAutomatic transaxle fluid colour is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed colour.
WARNING
Do not disconnect and inspect
spark plugs when the engine is hot.
You may burn yourself.

7WASHER FLUIDChecking the washer fluid level 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 sol-
vent with antifreeze characteristics in
cold climates to prevent freezing.
Check the parking brakeCheck 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 fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be checked by a HYUNDAI
authorised repairer.
Stroke : 6 “clicks’’ at a force of
44 lbs (20 kg, 196 N).
WARNING -
Coolant
 Do not use radiator coolant orantifreeze in the washer fluid
reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to paint and body trim.
 Windscreen Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
 Windscreen washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contact-
ing windscreen washer fluid.
Serious injury or death could
occur.

7BATTERYFor best battery service Keep the battery securely mounted.
 Keep the battery top clean and dry.  Keep the terminals and connections
clean, tight, and coated with petroleum
jelly or terminal grease.
 Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
 If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
✽ ✽ NOTICEBasically equipped battery is mainte-
nance free type. If your vehicle is
equipped with the battery marked with
LOWER and UPPER on the side, you
can check the electrolyte level. The elec-
trolyte level should be between LOWER
and UPPER. If the electrolyte level is
low, it needs to add distilled (demineral-
ized) water (Never add sulfuric acid or
other electrolyte). When refill, be care-
ful not to splash the battery and adja-
cent components. And do not overfill the
battery cells. It can cause corrosion on
other parts. After then ensure that tight-
en the cell caps. We recommend that you
contact a HYUNDAI authorised repair-
er.
WARNING
- Battery
dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and all other flames or sparks
away from the battery.
Hydrogen, a highly com- bustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.

3. Check the removed fuse; replace it if itis blown. To remove or insert the fuse,
use the fuse puller in the engine com-
partment fuse panel.
4. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, we recommend that
you consult a HYUNDAI authorised
repairer.
Main fuseIf the main fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative battery cable. 3. Remove the nuts shown in the picture
above.
4. Replace the fuse with a new one of the same rating.
5. Reinstall in the reverse order of removal.
CAUTION
After checking the fuse box in theengine compartment, securelyinstall the fuse box cover. If not,electrical failures may occur fromwater leaking in.
