Air Cleaner Filter
We recommend that the air cleaner filter
be replaced by an authorized retailer of
Genesis Branded products.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
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 maintenance
schedule.
Automatic Transmission Fluid

not be checked under normal usage
conditions, the Automatic transmission
fluid should be changed by an authorized
retailer of Genesis Branded products
according to the maintenance schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)

9-17
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal and
cables.
Brake Discs, Pads, Calipers and
Rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for
fluid leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks,
deterioration, or damage. Start
the engine and listen carefully for
any exhaust gas leakage. Tighten
connections or replace parts as
necessary.
Suspension Mounting Bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering Gear box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the engine
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks,

necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Maintenance9-24
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 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.
NOTICE

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

[ NEVER use brake fluid which has
been exposed to open air for an
extended time, 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
se only the specified brake fluid (refer
to Recommended ubricants and
Capacities section in chapter 2).

9-37
Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can
damage your vehicle’s aluminum
wheels. Use only approved wheel
weights.
Tire Replacement
Tread wear indicatorTread wear indicator
OHI078080
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.

[ Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.

[ When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.

[ Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, Genesis Branded Vehicle
recommends that tires be
replaced after six (6) years of
normal service.

[ Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.
