Maintenance9-16
Checking the Engine Oil Level
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.

6. Pull the dipstick out again and check the level. The level should be between
F (Full) and L (Low).
OTMPH091012N
7. If the oil level is below L, add enough oil to bring the level to F.
Use only the specified engine oil (Refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
NOTICE
To prevent damage to your engine:

[ Do not spill engine oil when adding
or changing engine oil. Wipe off
spilled oil immediately.

[ The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).

[ The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it
if necessary.

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 be changed by an authorized
HYUNDAI dealer according to the
Oil Life Management System 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.
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.

Recommended coolant

[When adding coolant, use only
deionized water, distilled water or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.

[ An incorrect coolant mixture can
result in severe malfunction or
engine/hybrid system damage.

[ The engine in your vehicle has
aluminum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.

[ Do not use alcohol or methanol
coolant or mix them with the specified
coolant.

[ Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixing percentage, refer to the
following table:
Ambient
Temperature Mixture Percentage
(volume)
Antifreeze Water
5°F (-15°C) 35 65
-

13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -31°F
(-35°C) and higher.

Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage. This
is a normal condition associated with
the wear of the brake linings. If the fluid
level is excessively low, we recommend
that the brake system be checked by an
authorized HYUNDAI dealer.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. We
recommend that the vehicle be
inspected by an authorized HYUNDAI
dealer.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
