EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

Checking the Engine Oil and
Filter

[The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil
and filter changed by an authorized
retailer of Genesis Branded
products according to the Oil Life
Management System instructions
or the Maintenance Schedule at the
beginning of this chapter.

[If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.

[To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.

[The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
Information
When the oil pressure is low due to
insufficient engine oil, the Engine
Oil Pressure (
) warning light will
illuminate. In addition, the enhanced
engine protection system, which limits
the engine's power is activated and the
Malfunction Indicator Lamp (
) will
illuminate when the vehicle is driven in
this state continuously. When oil pressure
is restored, the Engine Oil Pressure
warning light will turn off and the engine
power will no longer be limited.
However, for 3.5 T-GDI and 3.5 T-GDI
48 V MHEV, when the oil pressure is
restored, the warning light and the
enhanced engine protection system will
turn off after the engine is restarted.
CAUTION
The engine oil is very hot
immediately after the vehicle has
been driven and can cause burns
during replacement. Replace the
engine oil after the engine oil has
cooled down.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.
