This warning light illuminates:
When the power is limited for the
safety of the electric vehicle.
The power is limited for the following
reasons.
- The high voltage battery level is
below a certain level or voltage is
decreasing
- The temperature of the motor or
high voltage battery is too high or
too low
- There is a problem with the cooling
system, or a failure that may inter-
rupt normal driving Do not accelerate or start the
vehicle suddenly when the
power down warning light is ON.
When the high voltage battery
level is low, the power down
warning illuminates and the
power output from the vehicle is
limited. Charge the battery
immediately since your vehicle
may not drive uphill or skid on a
slope with the warning light ON.

Battery Overheated!
Stop vehicle
This warning message is displayed
to protect battery and electric vehicle
system when the high voltage bat-
tery temperature is too high.
Turn off the POWER button and stop
the vehicle so that the battery tem-
perature decreases.
Power limited
In the following cases, this warning
message is displayed when the vehi-
cle’s power is limited for safety.
When the high voltage battery is
below a certain level, or voltage is
decreasing.
When the temperature of the motor
or high voltage battery is too high
or too low.
When there is a problem with the
cooling system or a failure that
may interrupt normal driving. When this warning message is
displayed, do not accelerate or
start the vehicle suddenly.
When the high voltage battery
level is low, the power down
warning illuminates and the
power output from the vehicle is
limited. Charge the battery
immediately since your vehicle
may not drive uphill or skid on a
slope with the warning light ON.

Never place anything near the
sensor to ensure better control of
the heating and cooling system.
Manual Heating and Air
Conditioning
The heating and cooling system can
be controlled manually by pushing
buttons other than the AUTO button.
In this case, the system works
sequentially according to the order of
buttons selected.
When pressing any button except the
AUTO button while using automatic
operation, the functions not selected
will be controlled automatically.
1. Start the vehicle ( indicator
ON).
2. Set the mode to the desired posi-
tion.
To improve the effectiveness of
heating and cooling:
- Heating:
- Cooling:3. Set the temperature control to the
desired position.
4. Set the air intake control to the
outside (fresh) air position.
5. Set the fan speed control to the
desired speed.
6. If air conditioning is desired, turn
the air conditioning system on.
7. Press the AUTO button in order to
convert to full automatic control of
the system.

Air conditioning
All HYUNDAI Air Conditioning
Systems are filled with environmen-
tally friendly R-134a refrigerant.
1. Start the vehicle.
2. Push the air conditioning button.
3. Set the mode to the Face Level
mode.
4. 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.
5. 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.
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
recirculated air to the fresh outside
air position.
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 with the win-
dows and sunroof closed.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance. If you operate air conditioner
excessively, the difference between
the temperature 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
control to the lower speed.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set the
mode to the floor-defrost position.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, side view mirrors, and all side
windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.To Defog Inside Windshield
1. Select desired fan speed.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically.
If the outside (fresh) air position is
not selected automatically, adjust the
corresponding button manually.
If the position is selected, lower
fan speed is adjusted to a higher fan
speed.

Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious or
death. In this case, set the mode
selection knob or button to the
position and fan speed con-
trol knob or button to a lower
speed.
WARNING

Driving your vehicle
5
Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects or
materials in the motor compart-
ment
Placement of foreign object or mate-
rials which prevent cooling of the
vehicle, in the motor compartment,
may cause a failure. The manufactur-
er is not responsible for the damage
caused by such placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

What to do in an emergency
6
1. Pull off the road and stop as soon
as it is safe to do so.
2. Shift to P (Park) and set the park-
ing brake. If the air conditioning is
on, turn it off.
3. If coolant is running out under the
vehicle or steam is coming out
from the hood, stop the vehicle.
Do not open the hood until the
coolant has stopped running or
the steaming has stopped. If there
is no visible loss of coolant and no
steam, leave the vehicle running
and check to be sure the vehicle
cooling fan is operating. If the fan
is not running, turn the vehicle off.
4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If coolant is leaking out, stop the
vehicle immediately and call the
nearest authorized HYUNDAI
dealer for assistance.6. If you cannot find the cause of the
overheating, wait until the radiator
temperature has returned to nor-
mal. Then, if coolant has been
lost, call an authorized HYUNDAI
dealer for assistance.
Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by an author-
ized HYUNDAI dealer.
