Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.i
Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.

Convenient features of your vehicle
When the gauge indicator gets out
of the normal range, toward the
“H” position, it indicates overheat-
ing of the engine. It may damage
the engine.
Do not continue driving with the
overheated engine. For further
information, refer to “If the Engine
Overheats” in the chapter 6.
Outside Temperature Gauge
This gauge indicates the current out-
side air temperatures either in
Celsius (°C) or Fahrenheit.
- Temperature range : -40°F ~ 140°F
(-40°C ~ 60°C)
The outside temperature on the dis-
play may not immediately change
like a general thermometer not to
distract the driver.
The temperature unit (from °F to °C
or ~ °F to °C) can be changed by: - User Settings Mode in the Cluster :
You can change the temperature
unit in the “Other Features -
Temperature unit” .
- Automatic climate control system : While pressing the OFF button,
press the AUTO button for 3 sec-
onds or more.
The temperature unit of the instru-
ment cluster and climate control sys-
tem will change at once.
NOTICE
OLFH045208N
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and may cause severe burn. Wait
until the engine cools down
before adding coolant to the
reservoir.
CAUTION

What to do in an emergency7. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. 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.
8. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Never remove the
radiator cap and/or
inverter coolant cap
or the drain plug
while the engine and
radiator are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap and/or
inverter coolant cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

Maintenance
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/Inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage con-
ditions. But in severe conditions, the
fluid should be changed at an author-
ized HYUNDAI dealer in accordance
to the scheduled maintenance at the
beginning of this chapter.
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker. This is a normal con-
dition and you should not judge
the need to replace the fluid based
upon the changed color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
NOTICE
The use of a non-specified fluid
could result in transaxle mal-
function and failure. Use only
the specified automatic
transaxle fluid (refer to
“Recommended Lubricants and
Capacities” in chapter 8).

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.Checking the engine/inverter
coolant level

■ Radiator cap
■Inverter coolant cap
Never remove the
radiator cap and/or
inverter coolant cap
or the drain plug
while the engine and
radiator are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the hybrid system off and
wait until the engine cools
down. Use extreme care when
removing the radiator cap
and/or inverter coolant cap.
Wrap a thick towel around it,
and turn it counterclockwise
slowly to the first stop. Step
back while the pressure is
released from the cooling sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turn-
ing counterclockwise to remove
it.

Maintenance
Changing engine coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this chapter.
To prevent damage to engine
parts, put a thick towel around the
radiator cap before refilling the
coolant to prevent the coolant
from overflowing into engine
parts, such as the generator.
Checking the hybrid starter &
generator (HSG) belt
Have the hybrid starter & generator
(HSG) belt inspected or replaced
according to the Maintenance
Schedule in this chapter by an
authorized HYUNDAI dealer.

Turn the vehicle off while you
inspect the engine or hybrid
starter & generator(HSG) belt.
Otherwise it may result in
serious injury.
Keep hands, clothing etc.
away from the hybrid starter &
generator (HSG) belt.
WARNING
When the HSG belt is worn out
or damaged, replace the belt.
Otherwise, it may cause engine
overheating or battery dis-
charge.
CAUTIONDo not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control
resulting in an accident.
Engine coolant may also cause
damage to paint and body trim.
