Engine Coolant Temperature
Gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is in the ON position.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.WARNING
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could cause severe burns.
Wait until the engine is cool
before adding coolant to the
reservoir.
CAUTION
If the gauge pointer moves
beyond the normal range area
toward the “H” position, it indi-
cates overheating that may
damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to “If the
Engine Overheats” in chapter 6.

Charging System
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 there is a malfunction with
either the alternator or electrical
charging system.If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
alternator drive belt for looseness
or breakage.
If the belt is adjusted properly,
there may be a problem in the
electrical charging system.
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer as soon as pos-
sible.
Engine Coolant
Temperature Warning
Light (if equipped)
This warning light illuminates:
When the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 6.
CAUTION - Engine
Overheating
Do not continue driving with the
engine overheated. Otherwise
engine may be damaged.

Low Tire Pressure
Warning Light
This warning light illuminates:
Once you set the ignition switch or
Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
When one or more of your tires are
significantly underinflated.
For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 6.This warning light remains on after
blinking for approximately 60 seconds
or repeats blinking and off at the
intervals of approximately 3 seconds:
When there is a malfunction with
the TPMS.
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer as soon as possi-
ble.
For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 6.
WARNING - Safe Stopping
The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
If you notice any vehicle insta-
bility, immediately take your
foot off the accelerator pedal,
apply the brakes gradually with
light force, and slowly move to
a safe position off the road.
WARNING - Low tire
pressure
Significantly low tire pressure
makes the vehicle unstable
and can contribute to loss of
vehicle control and increased
braking distances.
Continued driving or low pres-
sure tires will cause the tires to
overheat and fail.

Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the
recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
4. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed.
✽ ✽
NOTICE
• While using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation may cause engine over-
heating. Continue to use the blow-
er fan but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
• Opening the windows in humid
weather while air conditioning
operates may create water
droplets inside the vehicle. Since
excessive water droplets may
cause damage to electrical equip-
ment, 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
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
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 sys-
tem operation characteristic.

Clothes hanger (if equipped)
To hang items, pull down the upper
portion of the hanger. (Type A)
These hangers are not designed to
hold large or heavy items.
CAUTION
To prevent damage to the Power
Outlets:
Use the power outlet only
when the engine is running
and remove the accessory
plug after use. Using the
accessory plug for prolonged
periods of time with the
engine off could cause the
battery to discharge.
Only use 12V electrical acces-
sories which are less than 15A
in electrical capacity.

Adjust the air-conditioner or
heater to the lowest operating
level when using the power
outlet.
Close the cover when not in
use.
Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices
may cause excessive audio
static and malfunctions in
other electronic systems or
devices used in your vehicle.
Push the plug in as far as it
will go. If good contact is not
made, the plug may overheat
or the internal temperature
fuse may open.WARNING
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outlet
with a wet hand.

Good driving practices
Never take the vehicle out of gear
and coast down a hill. This is
extremely dangerous.
Don't "ride" the brakes. This can
cause the brakes and related parts
to overheat and malfunction.
When you are driving down a long
hill, slow down and shift to a lower
gear. Engine braking will help slow
down the vehicle.
Slow down before shifting to a
lower gear. This will help avoid
over-revving the engine, which can
cause damage.
Slow down when you encounter
cross winds. This gives you much
better control of your vehicle.
Be sure the vehicle is completely
stopped before you shift into R
(Reverse) to prevent damage to
the transaxle. 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 accidentCAUTION
To prevent damage to the
engine, clutch and transaxle:
When downshifting from 5th
gear to 4th gear, be careful not
to inadvertently push the shift
lever sideways engaging the
2nd gear. A drastic downshift
may cause the engine speed
to increase to the point the
tachometer will enter the red-
zone.
Do not downshift more than
two gear at a time or down-
shift the gear when the engine
is running at high speed
(5,000 RPM or higher).
WARNING
Do not use the engine brake
(shifting from a higher gear to
lower gear) rapidly on slippery
roads. The vehicle may slip
causing an accident.
