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.

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.

Maintenance07
Tire rotation
To balance worn-out levels of the tire
tread, rotating the tire positions is
required every 7,500 miles (12,000
km), or sooner, when the irregular
abrasion is detected. While rotating
the positions, correctly balance the
tire positions.
When rotating tires, check for any
uneven abrasion and damage.
Abnormal tire abrasion is usually
caused by improper tire pressure,
tilted wheel alignment, unbalanced
wheels, severe braking or hard cor-
nering. Check for any bump or
bulging from the tire side walls. When
finding one of those, replace you tire.
Replace the tire, when a tire cord
fabric is visible. After rotation, make
sure to properly inflate the tires to the
recommended pressure, as speci-
fied, and check the lug-nut tightness.
Disc brake pads should be inspectedfor any abrasion, whenever rotatingtires.
Information
The front tire size is different from the
rear tire size. So when you rotate tires,
check sizes of the tires and wheels.
Wheel alignment and tire bal-
ance
The wheels are finely aligned and
balanced at the manufacturing facto-
ry in order to ensure the longest tire
life and the best driving performance.
In most cases, you do not need to
realign the wheels. However, when
detecting unusual tire abrasion or
vehicle leaning to one side, the
realignment may be needed. When
your vehicle vibrates on an even sur-
face, while driving, your wheels may
need to be rebalanced.
Improperly overweighted wheel
may damage your vehicle's alu-
minum wheels. Carry only the
appropriate wheel weights.
NOTICE

OBK079038
Without a spare tire
Do not use the compact spare
tire for tire rotation.
Never mix bias-ply tires and radial-ply tires under any cir-
cumstances. This may cause
abnormal handling, possibly
resulting in a death, severe
injury, or property damage.
WARNING

Maintenance
Tire replacement
When a tire unevenly wears out, a
tread wear indicator, in a pattern of a
solid band, appears over the tread.
This indicates that there is less than
1/16 inch (1.6 mm) of tread left.
When finding it, replace the tire.
Do not delay the tire replacement,
until all the indicators appear over
the entire tire tread.
OEN076053
Tread wear indicator
- Replacing tires
To reduce the risk of a serious
or fatal injury, caused by a tire
failure or a loss of vehicle con-
trol, follow the below warnings:
Replace tires, which areseverely worn out, unevenly
wear out, or damaged. Worn-
out tires may degrade the
braking effects, steering con-
trol, and traction.
Do not drive your vehicle with overinflated or underinflated
tires. This may cause uneven
abrasion or a tire failure.
(Continued)
(Continued)
When replacing tires of yourvehicle, never mix radial-ply
tires and bias-ply tires. You
must replace all the tires
(including the spare) when
changing from radial-ply tires
to bias-ply tires.
Tires and wheels in the differ- ent sizes may cause abnormal
handling and poor vehicle
control, resulting in a serious
accident.
Wheels, which do not satisfy the HYUNDAI’s specifications,
may be unfit and result in a
vehicle damage, abnormal
handling and poor vehicle
control.
The ABS operates upon com- paring the wheel speeds. A
tire size determines a wheel
speed. When replacing tires,
all the tires must be in the
same size as the original
ones. Installing tires in a dif-
ferent size may cause irregu-
lar operation of the ABS (Anti-
lock Brake System) and ESC
(Electronic Stability Control).
