Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the engine
coolant reservoir.
• Check the windscreen washer fluid
level.
• Check for low or under-inflated
tyres.
Whilst operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on smooth, level
road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle
P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
• Check for loose wheel nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

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
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
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 excessive amount of
foreign matter accumulates 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 an authorised HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorised HYUNDAI
dealer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.

ENGINE OIL
Checking the engine oil level
1. Ensure the vehicle is on level
ground.
2. Start the engine and allow it to
reach normal operating tempera-
ture.3. Turn the engine off and wait for
about 5 minutes for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean,
and re-insert it fully.5. Pull the dipstick out again and
check the level. The level should
be between F and L.
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
WARNING •Do not overfill the engine oil.
It may damage the engine.
•Do not spill engine oil, when
adding or changing engine
oil. If you drop the engine oil
on the engine room, wipe it off
immediately.
•When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.

Maintenance
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.

(Refer to “Recommended lubricants
and capacities” in section 8.)
Checking the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an autho-
rised HYUNDAI dealer.
Used engine oil may cause irri-
tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soap
and warm water as soon as pos-
sible after handling used oil.

Maintenance
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact
with your eyes. If brake fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh tap water. Have your eyes
examined by a doctor as soon
as possible.
WARNING
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result. Brake
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 disposed 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 system can damage
brake system parts.
CAUTION
