of the switches to warm the driver's seat
or front passenger's seat.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the switches in the
OFF position.
NOTICE
The seat warmers can cause a
SERIOUS BURN, even at low tem-
peratures and especially if used for
long periods of time.
Passengers must be able to feel if
the seat is becoming too warm so
they can turn it off, if needed.
People who cannot detect tempera-
ture change or pain to the skin
should use extreme caution, espe-
cially the following types of pas-
sengers:
Infants, children, elderly or dis-
abled persons, or hospital outpa-
tients.
People with sensitive skin or who
burn easily.
Fatigued individuals.
Intoxicated individuals.
People taking medication that
can cause drowsiness or sleepi-
ness.
WARNING
NEVER place anything on the seat
that insulates against heat when
the seat warmer is in operation,
such as a blanket or seat cushion.
This may cause the seat warmer to
overheat, causing a burn or dam-
age to the seat.

If the gauge pointer moves beyond the
normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the Engine
Overheats" in chapter 6.
Fuel gauge
This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in chap-ter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will illuminate
when the fuel tank is nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
NOTICE
iNOTICE
Running out of fuel can expose
vehicle occupants to danger. You
must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
"E (Empty)" level.
WARNINGNever remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severely burn.
Wait until the engine is cool before
adding coolant to the reservoir.

Operation Tips
To keep dust or unpleasant fumes fromentering the car through the ventilation
system, temporarily set the air intake
control to the recirculated air position.
Return the control to the fresh air posi-
tion when the irritation has passed.
This will help keep the driver alert and
comfortable.
To prevent the inside of the windshield from fogging, set the air intake control
to the fresh air position and fan speed
to the desired position, turn on the air
conditioning system, and adjust the
temperature control to desired temper-
ature.
Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly R-
134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recir- culated air position. However, pro-
longed operation of the recirculated air
position will excessively dry the air. In
this case, change the air position.
5. Adjust the fan speed control and tem- perature control to maintain maximum
comfort.
When maximum cooling is desired, set
the temperature control to the extreme
left position then set the fan speed con-
trol to the highest speed.
When using the air conditioning sys-
tem, monitor the engine temperature
gauge closely while driving up hills or
in heavy traffic when outside temper-
atures are high. Air conditioning sys-
tem operation can cause engine over-
heating. Continue to use the blower
fan, but turn the air conditioning sys-
tem off if the engine temperature
gauge indicates engine overheating.
Air conditioning system operation
tips
If the vehicle has been parked in direct sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
After sufficient cooling has been achieved, switch back from the recircu-
lated air to the fresh outside air posi-
tion.
To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system with the windows and sunroof
closed.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
If you operate air conditioner exces- sively, the difference between the tem-
perature of the outside air and that of
the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility. In this case,
set the mode selection knob or button
to the position and fan speed con-
trol to the lower speed.

Driving your vehicle
(Continued)
• When driving in Manual Shift Mode,slow down before shifting to a lower
gear. Otherwise, the lower gear may not
be engaged if the engine rpms are out-
side of the allowable range.
Shift-lock system
For your safety, the automatic transmis-
sion has a shift-lock system which pre-
vents shifting the transmission from P
(Park) into R (Reverse) unless the brake
pedal is depressed.
To shift the transmission from P (Park)
into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition switch in the ON position.
3. Move the shift lever.
Shift-lock release
If the shift lever cannot be moved from the
P (Park) position into R (Reverse) position
with the brake pedal depressed, continue
depressing the brake, and then do the fol-
lowing:
1. Place the ignition switch in the LOCK/OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) covering the shift-lock release access hole.
4. Insert a tool (e.g. flathead screwdriver) into the access hole and press down
on the tool.
5. Move the shift lever.
6. Remove the tool from the shift-lock override access hole then install the
cap. If you need to use the shift-lock release,
have your vehicle inspected by an author-
ized HYUNDAI dealer immediately.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
When you stay in the vehicle with
the engine running, be careful not
to depress the accelerator pedal
for a long period of time. The
engine or exhaust system may
overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away
from the exhaust system compo-
nents.
Do not stop or park over flamma-
ble materials, such as dry grass,
paper or leaves. They may ignite
and cause a fire.

Good Driving Practices
Never move the shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift into
R (Reverse) or D (Drive).
Do not move the shift lever to N (Neutral) when driving. Doing so may
result in an accident because of a loss
of engine braking and the transmission
could be damaged.
Do not drive with your foot resting on the brake pedal. Even light, but consis-
tent pedal pressure can result in the
brakes overheating, brake wear and
possibly even brake failure.
Depressing both accelerator and brake pedals at the same time can trigger
logic for engine power reduction to
assure vehicle deceleration. Vehicle
acceleration will resume after the
brake pedal is released.
Always apply the parking brake when leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving. Exercise extreme caution when driving
on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-
tor. To reduce the risk of SERIOUS
INJURY or DEATH:
ALWAYS wear your seatbelt. In a
collision, an unbelted occupant is
significantly more likely to be
seriously injured or killed than a
properly belted occupant.
Avoid high speeds when corner-
ing or turning.
Do not make quick steering
wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly
increased if you lose control of
your vehicle at highway speeds.
Loss of control often occurs if
two or more wheels drop off the
roadway and the driver over
steers to reenter the roadway.
In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
HYUNDAI recommends you fol-
low all posted speed limits.
