Safety system of your vehicle
Each time you push the switch, the
temperature setting of the seat is
changed as follows :
The seat warmer defaults to the OFF
position whenever the Engine Start/
Stop button is placed in the ON posi-
tion.
Information
With the seat warmer switch in the
ON position, the heating system in the
seat turns off or on automatically
depending on the seat temperature.
Battery cooling duct
The high voltage battery cooling duct
is located on the left side of the rear
seats. The cooling duct cools down
the high voltage battery. When the high voltage battery cool-
ing duct is blocked, the high voltage
battery may be overheated. Do not
obstruct the cooling duct with any
other objects.

Hybrid battery SOC (State of Charge) gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "L (Low)" level, the vehicle
automatically operates the engine to
charge the battery. However, if the
Service Indicator ( ) and
Malfunction Indicator Lamp (MIL)
( ) turn on when the SOC gauge
is near the "L (Low)" level, have the
vehicle be checked by an authorized
HYUNDAI dealer. Never try to start the vehicle if the
fuel tank is empty. In this condi-
tion, the engine cannot charge the
high voltage battery of the hybrid
system. If you try to start the vehi-
cle when the fuel is empty, the
high voltage battery will become
discharged and be damaged.

CD (Charge Depleting, Electric)
mode : The high-voltage (hybrid)
battery is used to drive the vehicle.
CS (Charge Sustaining, Hybrid) mode : The high-voltage (hybrid)

Information
Even when the battery charging rate
is high and driving in electric mode is
possible, engine may turn on in some
areas to protect the system.

Range
The range is the estimated distance
the vehicle can be driven with the
remaining fuel in the fuel tank
(Gasoline) and high-voltage (hybrid)
battery (Electric).
If the estimated distance is below 1
mph (1 km/h), the trip computer will
display "---" as the range.
Information
• If the vehicle is not on level groundor the battery power has been inter-
rupted, the range function may not
operate correctly.
• The range may differ from the actu- al driving distance as it is an esti-
mate of the available driving dis-
tance.
• The trip computer may not register additional fuel if less than 1.6 gallons
(6 liters) of fuel are added to the vehi-
cle.
• The range may vary significantly based on driving conditions, driving
habits, and condition of the vehicle.

What to do in an emergency
If You Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P (Park),
and apply the parking brake, and
place the Engine Start/Stop button
in the OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow the instructions provided later in
this chapter.
Hybrid vehicle
Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu- lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully. Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

Before Jump Starting
This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the HEV high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw to
prevent full discharge.
Using the 12V Battery ResetSwitch
1. Press the 12V Battery Reset
switch to reconnect the 12V bat-
tery.
2. Start the vehicle within 15 sec- onds of pressing the 12V Battery
Reset switch.
3. After starting vehicle ( indica- tor on), operate the vehicle safely
outdoors in ready mode stopped
and/or drive it for 30 minutes total
to charge the 12V battery fully. If you do not start the vehicle imme-
diately after pressing the 12V Battery
Reset switch, the power of 12V bat-
tery is automatically disconnected
after few seconds to save the 12V
battery from additional discharge. If
the 12V battery is disconnected prior
to starting the vehicle, press the 12V
Battery Reset switch again and then
immediately start the vehicle as
explained.
Repeated use of the 12V Battery
Reset switch without a sufficient
engine ON cycle (30 Min+) may
cause over discharge of the 12V bat-
tery, which will prevent the vehicle
from starting. If the 12V battery is
over discharged to a point that the
reset does not work, try to jump-start
the vehicle.
Information
After starting the vehicle ( indica-
tor on), the 12V battery is being
charged whether the engine is running
or not. Although there is no engine-
sound, it is unnecessary to depress the
accelerator pedal.

What to do in an emergency
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer.
Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1).
Information
The voltage range of the charger
should be 13.3~14V and its current
range should be less than 60A. (13.8V
is recommended).
Information
An inappropriately disposedbattery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
To prevent damage to your vehi-
cle:
• Only use a 12-volt power supply (battery or jumper system) to
jump start your vehicle.
Do not attempt to jump start your vehicle by push-starting.
NOTICE
ii
Pb
The use of an improper charg-
er with a voltage and current
range higher than specified
may cause overheating and
damage to the 12V battery.
The use of an incorrect charg-
er will lead to a power shut-off
to save the 12V battery. Stop
using the incorrect charger
once the power of the vehicle
is shut off.
CAUTION
