Features of your vehicle
Engine Oil Pressure
Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop Button to the ON
position.
- It remains on until the engine is
started.
• When the engine oil pressure is
low.
If the engine oil pressure is low:
1.Drive carefully to the nearest safe
location and stop your vehicle.
2.Turn the engine off and check the
engine oil level (For more details,
refer to “Engine Oil” in section 7). If
the level is low, add oil as required.
If the warning light remains on after
adding oil or if oil is not available,
we recommend that you have the
vehicle inspected by an authorized
HYUNDAI dealer as soon as possi-
ble.
Low Fuel Level Warning
Light
This warning light illuminates:
When the fuel tank is nearly empty.
If the fuel tank is nearly empty:
Add fuel as soon as possible.
CAUTION - Engine Oil
Pressure
Warning light
•
If the engine does not stop
immediately after the Engine
Oil Pressure Warning Light is
illuminated, severe damage
could result.
•If the warning light stays on
while the engine is running, it
indicates that there may be
serious engine damage or
malfunction. In this case,
1. Stop the vehicle as soon as
it is safe to do so.
2. Turn off the engine and
check the oil level. If the oil
level is low, fill the engine
oil to the proper level.
3. Start the engine again. If the
warning light stays on after
the engine is started, turn
the engine off immediately.
In this case, we recommend
that you have the vehicle
inspected by an authorized
HYUNDAI dealer.
CAUTION - Low Fuel

Driving with the Low Fuel Level
warning light on or with the fuel
level below “E” can cause the
engine to misfire and damage
the catalytic converter (if
equipped).

Features of your vehicle
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
WARNING - Vehicles
equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

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.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
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 transmission
occurs, check the transmission
fluid level.
• Check automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
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.

Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.CAUTION
• Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
• Do not use steel wool, abra-
sive cleaners, or strong deter-
gents containing highly alka-
line or caustic agents on
chrome-plated or anodized
aluminum parts. This may
result in damage to the pro-
tective coating and cause dis-
coloration or paint deteriora-
tion.
CAUTION
• Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical
circuits or engine and related
part located in the engine
compartment.
• Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents and air duct inside the
vehicle as this may damage
them.

Maintenance

• When cleaning underneath the car,
give particular attention to the
components under the fenders and
other areas that are hidden from
view. Do a thorough job; just damp-
ening the accumulated mud rather
than washing it away will acceler-
ate corrosion rather than prevent it.
Water under high pressure and
steam are particularly effective in
removing accumulated mud and
corrosive materials.
• When cleaning lower door panels,
rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.
Keep your garage dry
Don't park your car in a damp, poor-
ly ventilated garage. This creates a
favorable environment for corrosion.
This is particularly true if you wash
your car in the garage or drive it into
the garage when it is still wet or cov-
ered with snow, ice or mud. Even a
heated garage can contribute to cor-
rosion unless it is well ventilated so
moisture is dispersed.Keep paint and trim in good con-
dition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as
soon as possible.
Don't neglect the interior
Moisture can collect under the floor
mats and carpeting to cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fertil-
izers, cleaning materials or chemi-
cals in the car.
These should be carried only in
proper containers and any spills or
leaks should be cleaned up, flushed
with clean water and thoroughly
dried.Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er, and air freshener from contacting
the interior parts because they may
cause damage or discoloration. If
they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to
clean vinyl.
CAUTION
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
