Checking the engine oil level
1. Follow all of the oil manufacturer's
precautions.
2. Be sure the vehicle is on level
ground in P (Park) with the park-
ing brake set and the wheels
blocked.
3. Turn the engine on and allow the
engine to reach normal operating
temperature.
4. Turn the engine off and wait about
five minutes for the oil to return to
the oil pan.
5. Pull the dipstick out, wipe it clean,
and re-insert it fully.6. Pull the dipstick out again and
check the level. The level should
be between F and L.
7. If it is near or at L, add enough oil
to bring the level to F.
✽ ✽
NOTICE
To prevent damage to your engine:
• Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine is
not overfilled.
• Do not spill engine oil when
adding or changing engine oil. Use
a funnel to help prevent oil from
being spilled on engine compo-
nents. Wipe off spilled oil immedi-
ately.ODH077090N

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 pro-
longed 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.

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 cli-
mate.Checking the engine coolant
level
Never remove the
radiator cap, drain
plug and heater hose
connector cap while
the engine and radia-
tor are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
(Continued)
WARNING
(Continued)
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator 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 counterclock-
wise to remove it.

Maintenance
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.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 F and the L 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 F mark, but do not
overfill. If frequent additions are
required, we recommend that you
see an authorized retailer of Genesis
Branded products for a cooling sys-
tem inspection.
Recommended engine 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 improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified 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. 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.WARNING

Maintenance
For mixing percentage, refer to the
following table:
✽ ✽
NOTICE
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 tempera-
ture ranges of -31°F and higher.
Changing engine coolant
Have coolant changed by an author-
ized retailer of Genesis Branded
products according to the
Maintenance Schedule at the begin-
ning of this chapter.

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 acci-
dent.
Engine coolant may also
cause damage to paint and
body trim.
WARNING
To prevent damage to engine
parts, put a thick towel around
the radiator cap before refilling
the coolant to prevent the
coolant from overflowing into
engine parts, such as the gener-
ator.

Checking the brake fluid level
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 thor-
oughly to prevent brake fluid contam-
ination.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, have
the brake system checked by an
authorized retailer of Genesis
Branded products.
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
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.

Maintenance
✽ ✽
NOTICE
Use only the specified brake fluid
(refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).
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 wrong kind of
brake fluid. A few drops of
mineral based oil, such as
engine oil, in your brake sys-
tem can damage brake sys-
tem parts.
CAUTION
