Features of your vehicle
Engine coolant temperature gauge(if equipped)
This gauge shows the temperature of the
engine coolant when the ignition switchis ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in chapter 6.
Fuel gauge
The fuel gauge indicates the approximate amount of fuel remaining in the fuel tank.
The fuel tank capacity is given in chapter
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 warn-
ing light may come on earlier than usual
due to the movement of fuel in the tank.
OBA043107
CAUTION
If the gauge pointer moves beyondthe normal range area toward the
“H” it indicates overheating thatmay damage the engine.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

Features of your vehicle
Air conditioning (if equipped)
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Push the air condi-tioning button.
2. Set the mode to the position.
3. Set the air intake control to the recircu- lated air position. However, prolonged
operation of the recirculated air posi-
tion will excessively dry the air. In this
case, change the air position.
4. 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, set the air intake control to therecirculated air position, then set the
fan speed control to the highest speed.✽✽ NOTICE
 While using the air conditioning sys- tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
 While opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be used
with the windows closed.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.
To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehicle
by operating the air conditioning system.
During air conditioning system opera- tion, you may occasionally notice a slightchange in engine speed as the air con-
ditioning compressor cycles. This is a
normal system operation characteristic.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
When using the air conditioning system, you may notice clear water dripping (or
even puddling) on the ground under the
passenger side of the vehicle. This is a
normal system operation characteristic.
Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristics.

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. Good driving practices
Never move the shift lever from P
(Park) or N (Neutral) to any other posi-
tion with the accelerator pedaldepressed.
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 mayresult in an accident because of a loss
of engine braking and the transaxlecould 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.
When driving in sports 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.
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 controlresulting in an accident
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-
tor.
WARNING
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 flammable
materials, such as dry grass, paper
or leaves. They may ignite and
cause a fire.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off while driving, the power assist for the
brakes will not work. You can still stop
your vehicle by applying greater force to
the brake pedal than typical. The stop-
ping distance, however, will be longer
than with power brakes.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces. BRAKING SYSTEM (Continued)
To dry the brakes, lightly tap the brake pedal to heat up the brakes
while maintaining a safe forward
speed until brake performance
returns to normal. Avoid drivingat high speeds until the brakes
function correctly.WARNING
Take the following precautions:
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Applying the brakes
continuously will cause the
brakes to overheat and could
result in a temporary loss of brak-
ing performance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to oneside when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water.

Driving your vehicle
Check the Parking Brake Warning Light
by placing the ignition switch to the ON
position (do not start the engine). This light will be illuminated when the
parking brake is applied with the ignition
switch in the START or ON position.
Before driving, be sure the parking brake
is released and the Brake Warning Light
is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while engine is running, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-tion.
WK-23
CAUTION
Do not apply the accelerator
pedal while the parking brake is
engaged. If you depress theaccelerator pedal with the park-ing brake engaged, the warning will sound. Damage to the parking
brake may occur.
Driving with the parking brake on can overheat the braking systemand cause premature wear or
damage to brake parts. Make surethe parking brake is released andthe Brake Warning Light is offbefore driving.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud or sand:
Drive cautiously and allow extra distance
for braking.
Avoid sudden movements in braking or
steering.
If stuck in snow, mud, or sand, use sec-
ond gear. Accelerate slowly to avoid spin-
ning the drive wheels.
Use sand, rock salt, or other non-slip
material under the drive wheels to pro-
vide traction when stalled in ice, snow, or
mud. Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st and R
(Reverse, for manual transaxle vehicle)
or R (Reverse) and a forward gear (for
automatic transaxle vehicle). Try to avoid
spinning the wheels, and do not race the
engine.
To prevent transaxle wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator pedalwhile shifting, and press lightly on the
accelerator pedal while the transaxle is in
gear. Slowly spinning the wheels in for-
ward and reverse directions causes a
rocking motion that may free the vehicle.
SPECIAL DRIVING CONDITIONS
WARNING
Downshifting with an automatic
transaxle, while driving on slipperysurfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING
If the tires spin at high speed the
tires can explode, and you or oth-
ers may be injured. Do not attempt
this procedure if people or objects
are anywhere near the vehicle.
The vehicle can overheat causing
an engine compartment fire or
other damage. Spin the wheels as
little as possible and avoid spin-
ning the wheels at speeds over 56km/h (35 mph) as indicated on the
speedometer.
CAUTION
If you are still stuck after rocking the vehicle a few times, have thevehicle pulled out by a tow vehicle to avoid engine overheating, possi- ble damage to the transaxle, and
tire damage. See “Towing” in chap- ter 6.
To prevent damage to the transaxle,turn OFF the ESC (if equipped) priorto rocking the vehicle.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking
sound, the engine will probably be too
hot. If this happens, you should:
1. Pull the vehicle off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P (automatic transaxle) or Neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do notopen the hood until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leakage from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from it
when you stop). 5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call an authorized
HYUNDAI dealer. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, we recom-
mend that you call an authorized
HYUNDAI dealer.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and we recommend that the systembe checked by an authorized HYUNDAI dealer.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
