Maintenance
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 looseness in the

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 transmission occurs,
check the transmission fluid level.

[Check the parking brake.

[Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after

At least monthly:

[Check coolant level in the engine
coolant reservoir.

[Check the operation of all exterior
lights, including the stoplights, turn

Maintenance
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 conditions,
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
periodically for proper tension and
adjusted as necessary.
CAUTION
When you are inspecting the belt, place
the ignition switch to the lock/off or
ACC position.
Fuel filter (Except Europe)
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 a HYUNDAI authorised
repairer.
Fuel filter (For Europe)
This petrol powered vehicle is equipped
with a lifetime fuel filter that is
integrated with the fuel tank. Regular
maintenance or replacement is not
needed; however, the quality of fuel
used may impact the frequency of
maintenance needed. If there are any
fuel related problems like fuel flow
restriction, surging, loss of power,
hard starting problem etc, fuel filter
inspection or replacement may be
needed. We recommend the fuel filter
be inspected or replaced by a HYUNDAI
authorised repairer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connections be replaced by a
HYUNDAI authorised repairer.
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.
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

9-11
09
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 indicate 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
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, 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
We recommend that the air cleaner filter
be replaced by a HYUNDAI authorised
repairer.
Spark plugs
(for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transmission fluid/iMT
system actuator fluid
(if equipped)
Inspect the Manual transmission fluid/
iMT system actuator fluid according to
the maintenance schedule.
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid is changed by a
HYUNDAI authorised repairer according
to the maintenance schedule.
