OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
If you have any question, we recom-
mend that you consult an authorized
HYUNDAI dealer.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• 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 transaxle occurs,
check the transaxle fluid level.
• Check automatic transaxle P
(Park) function.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
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 (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authoized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age.
We recommend that the fuel lines,
fuel hoses and connectionsr be replaced
by an authoized HYUNDAI dealer.
WARNING - Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, since
the high currents in the
Common Rail system produce
considerable magnetic fields.

Maintenance
TIRES AND WHEELS
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.
Recommended cold tire infla-
tion 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 driven less than
1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire under-
inflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

WARNING - Tire
inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tire pressure
Always observe the following:
• Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km (1
mile) since startup.)
• Check the pressure of your
spare tire each time you check
the pressure of other tires.
• Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
• Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a greater possibility of dam-
age from road hazards.
CAUTION
• Warm tires normally exceed
recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
• Be sure to reinstall the tire
inflation valve caps. Without
the valve cap, dirt or moisture
could get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
