Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in theengine coolant reservoir.
Check the windshield washer fluid level.
Check the tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function. Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, 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-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the engine for several minutes,
and check the connections for any
leakages. Fuel filters should be
installed by an authorized retailer of
Genesis Branded products.
Fuel Lines, Fuel Hoses and
Connections
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.
Vacuum Crankcase Ventilation
Hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.

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
(if equipped)
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.
Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition 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 mal-
function and failure. Use only the
specified automatic transmission
fluid (refer to "Recommended
Lubricants and Capacities" in
chapter 8).

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
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, see
an authorized retailer of Genesis
Branded products for a cooling sys-
tem inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) 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
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol coolant or mix them with the spec-
ified coolant.

Maintenance
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:
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 and higher.
