Air ventilation seat (if equipped)
The air ventilation seat is provided to
cool the front seats during hot weath-
er by blowing air through small vent
holes on the surface of the seats.
While the engine is running, press
the cooling portion (blue color) of the
switch to cool the driver's seat or the
front passenger's seat.
When the operation of the seat cool-
er is not needed, keep the switches
in the OFF position.
WARNING
The seat warmers can cause a
SERIOUS BURN, even at low
temperatures 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 tem-
perature change or pain to the
skin should use extreme cau-
tion, especially the following
types of passengers:
Infants, children, elderly or
disabled persons, or hospital
outpatients.
People with sensitive skin or who burn easily.
Fatigued individuals.
Intoxicated individuals.
People taking medication that can cause drowsiness or
sleepiness.
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 damage to
the seat.
OANNSA2020CAUTION
To prevent damage to the seatwarmers and seats:
Never use a solvent such as paint thinner, benzene, alco-hol or gasoline to clean theseats.
Do not place heavy or sharp objects on seats equippedwith seat warmers.
Do not change the seat cover. It may damage the seatwarmer.

Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON.
CAUTION
Do not operate the engine with-in the tachometer's RED ZONE.This may cause severe enginedamage.
ODM046733
ODM046734WARNING

before adding coolant to the
reservoir.
CAUTION
If the gauge pointer movesbeyond the normal range areatoward the "H" position, it indi-cates overheating that maydamage the engine.
Do not continue driving with anoverheated engine. If your vehi-cle overheats, refer to "If theEngine Overheats" in chapter 6.

If the fuel tank is nearly empty:
Add fuel as soon as possible.
Low Tire PressureWarning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds and then goes off.
When one or more of your tires are significantly underinflated.
For more details, refer to "Tire

Operation Tips
To prevent dust or unpleasant
fumes from entering the vehicle
through the ventilation system,
temporarily set the air intake con-
trol to the recirculated air position.
Be sure to return the control to the
fresh air position when the irritation
has passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind- shield, 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
temperature.Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friend-
ly 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 operating the air
conditioning system 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 win-
dows closed.

AC inverter (if equipped)
The AC inverter supplies 115V/150W
electric power to operate electric
accessories or equipments.
(Continued)
Some electronic devices can cause electronic interferencewhen plugged into a vehicle’spower outlet. These devicesmay cause excessive audiostatic and malfunctions inother electronic systems ordevices used in your vehicle.
Make sure that the electric devices are plugged in secure-ly. If not, it could cause a mal-function of electric systems.
If you use an electric device with a battery, electric currentmay flow from the electricdevice into the vehicle andmay cause a malfunction ofelectric systems. Only useelectric devices which couldprevent inverse current.
WARNING
Do not put fingers or foreign
elements (pin, etc.) into a power
outlet and do not touch with a
wet hand. You may get an elec-
tric shock.
CAUTION
Use the power outlet only when the engine is runningand remove the accessoryplug after use. Using theaccessory plug for prolongedperiods of time with theengine off could cause thebattery to discharge.
Only use 10V electric acces- sories which are less than 10Ain electric capacity. If not, itcould lead to an overheatedpower outlet or electric wiringin the vehicle and electric sys-tems may malfunction.
Adjust the air-conditioner or heater to the lowest operatinglevel when using the poweroutlet.
Close the cover when not in use.
