Starting the Vehicle
Vehicles with smart key system
1. Carry the smart key or leave it inside
the vehicle.
2. Make sure the parking brake is firmly
applied.
3. Make sure the shift button is in P
(Park). With the shift button in N
(Neutral), you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop button.
If the hybrid system starts, the “” indicator will come on.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.
After following the start procedures, “
” indicator on the instrument cluster will turn on. For more details, please
check chapter 6.
ECONOMICAL and SAFE OPERATION of
Hybrid system
• Drive smoothly. Accelerate at a
moderate rate and maintain a steady
cruising speed. Do not make “jack-
rabbit” starts. Do not race between
stoplights.
• Avoid heavy traffic whenever possible.
Always maintain a safe distance
from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
• The regenerative brake generates
energy when the vehicle decelerates.
• When the hybrid battery power is
low, the hybrid system automatically
recharges the hybrid battery.
• When the engine is running with the
shift button in N (Neutral), the hybrid
system cannot generate electricity.
The hybrid battery cannot recharge
with the shift button in N (Neutral).
Information
In the hybrid system, the engine
automatically runs and stops. When
the hybrid system operates, the “
” indicator is illuminated.
In the following situation, the engine may
operate automatically.
-When the engine is ready to run
-When the hybrid battery is being
charged
-Depending on the temperature
condition of the hybrid battery
Special Features
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear
a sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear
an unconventional sound. When you
apply the brake pedal, you may hear
a sound from the regenerative brake
system. When the hybrid system is
turned off or on, you may hear a sound
in the engine compartment. If you
depress the brake pedal repeatedly
when the hybrid system is turned on,
you may hear a sound in the engine
compartment. None of these sounds
indicate a problem. These are normal
characteristics of hybrid vehicles.
If any of following occur, it’s a normal
condition if you hear a motor sound in
the engine compartment:
-After turning off the hybrid system,
the brake pedal is released.
-When the hybrid system is turned off,
the brake pedal is applied.
-When the driver door is opened.
DRIVING THE HYBRID VEHICLE

WARNING
If a fire occurs:
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P
(Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to
start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not
operate, refer to “If the 12 Volt Battery
Is Discharged” section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “If the 12 Volt Battery
Is Discharged” section in chapter
8. When the fuel level is low, do not
attempt to drive the vehicle only with
the battery power. The high voltage
battery may be discharged, and the
hybrid system will turn OFF.
