Maintenance
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 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.
NOTICE
When you are inspecting the belt, place
the ignition switch in the LOCK/OFF or
ACC position.
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 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 authoized HYUNDAI
dealer.
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
an authoized HYUNDAI dealer.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running the
diesel engine or within 30 seconds
after turning OFF the diesel engine. The
high-pressure pump, high-pressure
pipes, rail, and injectors are still subject
to high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out, it
may cause serious body injury. Any
people, who are implanted with the
artificial cardiac pacemaker, should
remain away from the ECU or the
wiring harness by at least 30 cm,
while running the diesel engine. The
high currents of the electronic engine
control system produce a considerable
amount of magnetic fields.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

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 an authorized HYUNDAI
dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Valve clearance (For 1.0 T-GDi)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
We recommend that the system be
serviced by an authorized HYUNDAI
dealer.
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.
Manual transmission fluid
(if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.
Automated manual transmission
fluid (if equipped)
Inspect the Automated manual
transmission fluid according to the
maintenance schedule.

Maintenance
NOTICE
The use of non-specified fluid
(even marked as compatible with
genuine) could result in shift quality
deterioration and vibrations,
eventually, the transmission failure.
Use only specified Automated
manual transmission fluid. (Refer
to “Recommended lubricants and
capacities” in chapter 2.)
Intelligent VariableTransmission
(IVT) Fluid (if equipped)
Intelligent Variable Transmission (IVT)
Fluid should not be checked under
normal usage conditions. But, the
Intel-ligent Variable Transmission (IVT)
Fluid should be changed under severe
usage conditions. We recommend that
the Intelligent Variable Transmission
(IVT) Fluid changed by an authorized
HYUNDAI dealer according to the
maintenance schedule. (Refer to
“Maintenance Under Severe Usage
Conditions” in this chapter.)
i Information
Intelligent variable transmission (IVT)
fluid color is basically light amber. As the
vehicle is driven, the intelligent variable
transmission (IVT) fluid will begin to
look darker. This is a normal condition
and you should not judge the need to
replace the fluid based upon the changed
color.
NOTICE
The use of non-specified fluid (even
marked as compatible with genuine)
could result in shift quality deteriora-
tion and vibrations, and eventual
transmission failure. Use only specified
Intelligent Variable Transmission
(IVT) fluid. (Refer to “Recommended
lubricants and capacities” in chapter 8.)

1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few
minutes (about 15 minutes) for the oil
to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and
reinsert it fully.
5. Pull the dipstick out again and check
the level. The level should be between
F (Full) and L (Low).

If it is near or at L (Low), add enough
oil to bring the level to F (Full). Do not
overfill.
Use a funnel to help prevent oil from
being spilled on engine components.
Use only the specified engine oil. (Refer
to “Recommended lubricants and
capacities” in chapter 2.)
