EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The 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 belts
Inspect 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
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. Fuel filters should be
installed by an authorised HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorised HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
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 within 30 cm of the ECU
or wiring harness within the engine
room whilst engine is running, high
currents used in the Common Rail
system produce considerable mag-
netic fields.
CAUTION
When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.

Maintenance
Vapour hose and fuel filler cap
The 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 filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (Petrol 1.6L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorised HYUNDAI dealer should
perform the operation.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
WARNING
Do not disconnect and inspect
spark plugs when the engine is hot.
You may burn yourself.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
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 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 fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorised
HYUNDAI dealer.
Stroke : 5 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
WARNING -Coolant
• Do not use radiator coolant or
antifreeze 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. Do not drink and avoid
contacting windscreen washer
fluid. Injury or death could occur.

BATTERY
For 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.
WARNING- Battery
dangers
Always read the following
instructions carefully when
handling a battery.
Keep light 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.
If any electrolyte gets into
your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
(Continued)
(Continued)
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel a
pain or a burning sensa-
tion, get medical attention
immediately.
Wear eye protection when
charging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose the battery
according to your local
law(s) or regulation.
• When lifting a plastic-cased bat-
tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
• Never attempt to recharge the
battery when the battery cables
are connected.

• The electrical ignition system
works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.CAUTION
• When you don’t use the vehicle
for a long time in the low temper-
ature area, separate the battery
and keep it indoors.
• Always charge the battery fully to
prevent the battery case dam-
aged in low temperature area.
• If you connect unauthorised elec-
tronic devices to the battery, the
battery may be discharged. Never
use unauthorised devices.
• Make sure the battery cap is
closed. If the battery cap is not
closed securely, it can malfunc-
tion because the electric compo-
nents are exposed to moisture.
WARNING
Separating the battery from the
vehicle should be done by an
authorised HYUNDAI dealer.

3. Check the removed fuse; replace it if it
is 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, consult an authorised
HYUNDAI dealer.
Multi fuse
If the multi fuse is blown, replace the fuse
with a new one of the same rating when
the ignition switch and all other switches
are off.
CAUTION
After checking the fuse panel in the
engine compartment, securely
install the fuse panel cover. If not,
electrical failures may occur from
water contact.
ORB070022
CAUTION
• Before removing the multi fuse,
disconnect the (-) terminal of bat-
tery.
• Do not disassemble or assemble
the multi fuse fastened with bolts
or nuts. The fuse may be fastened
incompletely, and it may cause a
possible fire. If the multi fuse is
blown, we recommend that you
consult an authorised HYUNDAI
dealer.
