Maintenance9-18
Checking the engine oil and
filter
OCN7092026

[ 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
HYUNDAI dealer according to the Oil
Life Management System function
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 gasoline 2.5 turbo engine
and 2.5 gdi engine, when the engine 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.

Maintenance9-20
Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.
WARNING
The electric motor for the cooling fan
may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

2. Make sure that the tiny protrusions inside the coolant cap are securely
interlocked.
