WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do
the work, we recommend that having it
done by an authorized HYUNDAI dealer.
ALWAYS follow these precautions for
performing maintenance work:

[Park your vehicle on level ground,
move the shift button into the P
(Park) position, apply the parking
brake, and place the ignition switch
in the LOCK/OFF position.

[ Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.

[ If you must run the engine during
maintenance, do so out doors or in
an area with plenty of ventilation.

[ Keep flames, sparks, or smoking
materials away from the battery and
fuel-related parts. The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used.
Owner Maintenance Schedule
When you stop for fuel:

[
Check the coolant level in the engine
coolant reservoir.

[ Check the windshield washer fluid
level.

[ Check for low or under-inflated tires.
WARNING
Be careful when checking your engine
coolant/inverter coolant level if the
engine is hot. This may result in coolant
being blown out of the opening and
cause serious burns and other injuries.
OWNER MAINTENANCE

Maintenance9-6
While 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
steering wheel, or change in its
straight-ahead position.

[ Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling 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 automatic transmission P
(Park) function.

[ Check the parking brake.

[ Check for fluid leaks under your
vehicle (water dripping from the air
conditioning 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
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.

[ Check for loose wheel lug nuts.
At least twice a year: (i.e., every
Spring and Autumn)

[Check radiator, heater and air
conditioning hoses for leaks or
damage.

[ Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.

[ Check headlamp alignment.

[ Check muffler, exhaust pipes, shields
and clamps.

[ Check the seat belts for wear and
function.
At least once a year:

[Clean body and door drain holes.

[ Lubricate door hinges and hood
hinges.

[ Lubricate door and hood locks and
latches.

[ Lubricate door rubber weather strips.

[ Check the air conditioning system.

[ Inspect and lubricate automatic
transmission linkage and controls.

[ Clean the battery and terminals.

[ Check the brake fluid level.

Information

[ As it is normal for engine oil to be consumed during driving, the engine oil level should
be checked on regular basis.

[ The engine oil change interval for normal operating conditions is based on the use of
the recommended engine specification. If the recommended engine oil specification
is not used, then replace the engine oil according to the maintenance schedule under
severe operating conditions.

[ The vehicle may be equipped with the Oil Life Management System that predicts
engine oil life based on the driver’s driving history and alerts the driver to change
engine oil.
- If the deterioration of the engine oil increases depending on the driver’s driving
style, the remaining oil life alert will appear on the instrument cluster before the
normal engine oil replacement interval. Have the engine oil and filter changed by an
authorized HYUNDAI dealer.
- Oil Life Management System works when the recommended engine oil is used.
If the recommended engine oil is not used, replace the engine oil according to the
maintenance schedule under severe usage conditions. Also, check the engine oil level
regularly as this system assumes that the engine oil is being filled norm\
ally.
- Always reset the remaining engine oil life whenever the engine oil is changed.
Otherwise, the indication of remaining Oil life in the Oil Life Management System
may not be accurate.To reset the Oil Change Reminder, select ‘RESET’ from the
instrument cluster or infotainment system screen. Then, select ‘Yes’ when the
message “Reset oil life?” or “Has the engine oil been changed? Press [Yes] to reset
the oil life.” appears on the screen.
- If there is no alert until the maximum maintenance interval, have the vehicle
checked by an authorized HYUNDAI dealer.

Normal Maintenance Schedule

Maintenance9-14
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.
HSG (Hybrid Starter & Generator)
Belt
The HSG belt should be changed at the
intervals specified in the maintenance
schedule.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
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.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
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
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe the 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.
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine Coolant/Inverter Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid is changed by an
authorized HYUNDAI dealer according to
the maintenance schedule.
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to the
intervals specified in the maintenance
schedule.
