Owner Maintenance Schedule
When you stop for fuel:

[ Check the coolant level in the engine
coolant reservoir or the liquid-cooled
intercooler coolant reservoir.

[ Check the windshield washer fluid
level.

[ Check for low or under-inflated tires.
WARNING
Be careful when checking your 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.
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: (for example,
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 headlight 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.

[ For 2.0 T-GDI engine : The vehicle may be e uipped with the Oil ife 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
severity, the remaining oil life alert appears on the instrument cluster before the
normal engine oil replacement interval. ave the engine oil and filter changed by an
authori ed distributor of Genesis Branded product.
- Oil ife Management System works when the recommended engine oil is used.
So, if recommended engine oil is not used, replace the engine oil according to the
maintenance schedule under severe usage condition.
Also, check the amount of engine oil regularly as this system assumes that the engine
oil is being filled normally.
- Always reset the remaining engine oil life whenever the engine oil is changed.
Otherwise, The indication of remaining Oil life in the Oil ife Management System
may not be accurate.
To reset the Oil Change Reminder, select RESET from the infotainment system
screen. Then, select Yes when the message Changed engine oil 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 authori ed distributor of Genesis Branded product.

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.
Information
hen you are inspecting the belt, turn the
engine off.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and

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 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 ensure 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.

ENGINE OIL
Checking the Engine Oil LevelNOTICE
Engine oil is used for lubricating,
cooling, and operating various
hydraulic components in the engine.
Engine oil consumption while driving
is normal, and it is necessary to check
and refill the engine oil regularly. Also,
check and refill the oil level within
the recommended maintenance
schedule to prevent deterioration of oil
performance.
Check the engine oil following the
below procedure.
1. Follow all of the oil manufacturer’s precautions.
2. Be sure the vehicle is on the level ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert it fully.
