Checking the Engine Oil and
Filter

[We recommend that the engine oil
and filter be changed by an authorized
retailer of Genesis Branded products
according to 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.
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.

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the
factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season and
before traveling to a colder climate.
Checking the Coolant Level
OIK090007
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN marks on
the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the MAX mark, but do not overfill.
If frequent additions are required, see an
authorized retailer of Genesis Branded
products for a cooling system inspection.
WARNING
Never remove the engine
coolant radiator cap, coolant
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under pressure,
causing serious injury.
Turn the vehicle off and wait until
the engine cools down. Use extreme
care when removing the radiator cap,
coolant cap. Wrap a thick towel around
it, and turn it counterclockwise slowly
to the first stop. Step back while the
pressure is released from the cooling
system. When you are sure all the
pressure has been released, press down
on the cap, using a thick towel, and
continue turning counterclockwise to
remove it.
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 is securely
interlocked.
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
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
TemperatureMixture 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.

Checking the Brake Fluid Level
OIK090009
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 retailer of Genesis Branded
products.
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 retailer of
Genesis Branded products.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake fluid
comes in contact with your eyes, flush
your eyes with clean water for at least
15 minutes and get immediate medical
attention.
NOTICE

[Do not allow brake fluid to contact
the vehicle’s body paint, as paint
damage will result.

[Brake fluid, which has been exposed
to open air for an extended time
should NEVER be used as its quality
cannot be guaranteed. It should be
disposed of properly.

[Do not use the incorrect type of
brake fluid. A few drops of mineral
based oil, such as engine oil, in your
brake system can damage brake
system parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
BRAKE FLUID

Maintenance
9-24
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:

[Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.

[Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.

[Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.

[Keep washer fluid away from
children and animals.
WARNING
Checking the Washer Fluid Level
OIK090010
