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.)
