Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
retailer of Genesis Branded prod-
ucts.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized retailer of
Genesis Branded products replace
any damaged or leaking parts imme-
diately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A Genesis/Hyundai Part air cleaner
filter is recommended when the filter
is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct part number and heat
range.

Maintenance
Valve clearance
(Lambda engine)
Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. Have an authorized retail-
er of Genesis Branded products per-
form the operation.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized retailer of Genesis
Branded products in accordance to
the scheduled maintenance at the
beginning of this chapter.
✽ ✽
NOTICE
Automatic transmission fluid color
is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal con-
dition and you should not judge the
need to replace the fluid based upon
the changed color.
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).
CAUTION

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.
Ambient
TemperatureMixture Percentage

Antifreeze Water

-13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
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.

Filter inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, remove
the stoppers on both sides to allow
the glove box to hang freely on the
hinges.2. Remove the support rod (1).
