3: Fuel filter & Fuel tank air filter are considered to be maintenance free\
but periodic inspection is recommended for this mainte-nance schedule depends on fuel quality. If there are some important safety matters like fuel flow restriction, surging, loss of
power, hard starting problem, etc. replace the fuel filter immediately regardless of maintenance schedule a\
nd consult an
authorized HYUNDAI dealer for details.
*
4: Inspect for excessive valve noise and/or engine vibration and adjust if necessary. Have an authorized HYUNDAI dealer per- form the operation.

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 HYUNDAI
dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
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.

Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver's side center
pillar.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering control, or 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 recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and on
the tire label located on the dri-
ver's side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-
ing poor handling.
Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.

Maintenance
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. "Cold tires" means the
vehicle has not been driven for at
least three hours or has been driven
for less than one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.
WARNING
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
Over-inflation produces a
harsh ride, excessive wear at
the center of the tire tread,
and a greater possibility of
damage from road hazards.

Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.
Intended Outboard Sidewall
The side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light truck(LT) tire
A tire designated by its manufacturer
as primarily intended for use on light-
weight trucks or multipurpose pas-
senger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.
Load Index
An assigned number ranging from 1
to 279 that corresponds to the load
carrying capacity of a tire.
Maximum Inflation Pressure
The maximum air pressure to which
a cold tire may be inflated. The max-
imum air pressure is molded onto the
sidewall.
