Engine oil and filter
The engine oil and filter should be
changed at the interval, as specified
in the maintenance schedule. After
driving in severe conditions, you
should more frequently change oil
and filters.
Drive belts
Inspect all belts for any cut, crack,
excessive wear-out, or oil saturation.
If necessary, replace it.
Fuel filter
A clogged filter may limit the acceler-
ating function, damage the emission
system and cause other problems,
such as hard starting. When an
excessive amount of foreign sub-
stances accumulate in the fuel tank,
you should more frequently replace
the filter. After installing a new filter,
run the engine for several minutes,
and check for any leakage from the
connections. Fuel filters should be
installed by an authorized EQUUS
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for any leakage and
damage. Immediately have an
authorized EQUUS dealer replace
any damaged or leaking parts.
Vapor hose and fuel filler cap
Check the fuel lines, fuel hoses and
connections for any leakage and
damage. Immediately have an
authorized EQUUS dealer replace
any damaged or leaking parts.
Air cleaner filter
An authorized HYUNDAI air cleaner
filter is recommended.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system compo-
nents, such as radiator, coolant
reservoir, hoses and connections, for
any leakage and damage. If neces-
sary, replace any damaged parts.
Coolant
The coolant should be changed at
the interval, as specified in the main-
tenance schedule.
Automatic transmission fluid
You do not need to check the auto-
matic transmission fluid, when driv-
ing under normal conditions.
However, after driving in severe con-
ditions, the fluid should be changed
by an authorized EQUUS dealer in
accordance with the maintenance
schedule, as specified in the begin-
ning of this chapter.
Information
The original color of the automatic
transmission fluid is red. However, as
you drive the vehicle, the color will
become darker. This is normal, and
you do not need to change the fluid
due to the changed color.

Maintenance
The use of an unauthorized fluid
may result in transmission mal-
function and failure. Use only the
authorized automatic transmis-
sion fluid. (Refer to “Recommended
lubricants and capacities” in the
chapter 8.)
Brake hoses and lines
Confirm the proper installation, and
check for any frictions, cracks, dete-
rioration and leakage. If necessary,
immediately replace any deteriorated
or damaged parts.
Brake fluid
Check the brake fluid level. The level
should be between “MIN” and “MAX”
marks on the reservoir. Use only the
hydraulic brake fluid, which meet the
requirements of the DOT3/DOT4
specifications.
Brake discs, pads, calipers
and rotors
Check the pads and the disc for any
excessive wear-out, and inspect
calipers for any fluid leakage.
Exhaust pipe and muffler
Inspect the exhaust pipes, muffler
and hangers for any cracks, deterio-
rations, or damages. Start the
engine, and listen carefully for any
gas leaking noise. If necessary, tight-
en connections or replace the dam-
aged parts.
Suspension mounting bolts
Check the suspension connections
for any looseness or damage. If nec-
essary, retighten the bolt to the spec-
ified torque.
Steering gear box, linkage &
boots/lower arm ball joint
After stopping the vehicle and turn-
ing off the engine, confirm the steer-
ing locking (tightening).
Check the bends for any linkage or
damage. Check the dust boots and
ball joints for any deterioration,
cracks, or damage. If necessary,
replace the damaged parts.
Power steering pump, belt and
hoses
Check the power steering pump and
hoses for any leakage or damage. If
necessary, immediately replace any
damaged or leaking parts. Inspect
the power steering belt (or drive belt)
for any cuts, cracks, excessive wear-
out, oil saturation or looseness. If
necessary, replace or adjust the
damaged part.
Drive shafts and boots
Check the drive shafts, boots and
clamps for any cracks, deterioration,
or damage. If necessary, replace or
grease the damaged part.
Air conditioning refrigerant
Check the air conditioning lines and
connections for any leakage or dam-
age.

Checking the engine oil level
1. Be sure the vehicle is on levelground.
2. Start the engine and allow it to reach a normal operating temper-
ature.
3. Turn the engine off and wait for the oil fluctuation to stabilize in the oil
pan (approximately 5 minutes).
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
5. Pull the dipstick out again and check the level. The level should
be between F and L. Do not overfill the engine oil.
This may damage the engine.
while adding or changing it. If
you spill out the engine oil in the
engine compartment, immedi-
ately wipe it off.
When it is near to or at L, add the
engine oil to bring it up to F. Do not
overfill it.
Use a funnel to prevent oil spillage
over the engine components.
Use only the authorized engine oil. (Refer to “Recommended lubricantsand capacities” in the chapter 8.)

Maintenance
Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized EQUUS dealer in
accordance with the Maintenance
Schedule, as specified in the begin-
ning of this chapter.
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.

Changing the coolant
Have coolant changed by an author-
ized EQUUS dealer in accordance
with the Maintenance Schedule, as
specified in the beginning of this
chapter.
Cover a thick cloth around the
radiator cap, before refilling the
coolant, in order to prevent the
coolant spillage over the engine
parts, such as the generator.
NOTICE
OVI075005N
Radiator cap
Do not remove the radiator cap,
when the engine and radiator
are hot. Hot coolant and steam
may blow out under pressure
and burn your skin, causing a
serious injury.
WARNING
- Coolant
Do not fill the radiator coolant or antifreeze in the washer
fluid reservoir.
Radiator coolant may obscure your visibility, when sprayed
on the windshield. This may
cause loss of vehicle control,
or damage the paint and body
trim.
WARNING

Maintenance
Checking the brake fluid level
Check the fluid level in the reservoir
on a regular basis. The fluid level
should be between MAX and MIN
marks on the reservoir.
Before opening the reservoir cap to
add brake fluid, clean the area
around the reservoir cap to prevent
brake fluid from being contaminated.
When the level is low, add fluid near
to the MAX level. The level decreas-
es, as the vehicle drives. This is a
normal, associated with the wear-out
of the brake linings. When the fluid
level is excessively low, have the
brake system checked by an author-
ized EQUUS dealer.
Use only the authorized brake fluid.(Refer to “Recommended lubricantsor capacities” in the chapter 8.)
Never mix different types of fluid.
Do not spill the brake fluid over
the body paint. This may damage
the paint. The brake fluid, which is
exposed in the air for an extended
period of time, should not be
used, as its quality cannot be
guaranteed. It should be disposed
in a proper manner. Do not add
unauthorized fluid. A few drops of
mineral-based oil, such as engine
oil, in your brake system may
damage brake system parts.

- Loss of brake fluid
When the brake system
requires frequent fluid addition,
the vehicle should be inspected
by an authorized EQUUS dealer.
WARNING
- Brake fluid
When changing and adding
brake fluid, pay special atten-
tion to it. Before washing your
hands, do not touch your eyes.
When the brake fluid should
come in contact with your eyes,
immediately wash them with
fresh tap water. Immediately
have your eyes examined by a
doctor.
