Starting the vehicle
1. Carry the smart key or leave it
inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in P (Park). With the shift lever in N (Neutral),
you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on and a
double chime can be heard.
Whether the engine is cold or warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, " " indicator on the
instrument cluster will turn on.
For more information, please
check Chapter 5. ECONOMICAL and SAFE OPERA-
TION 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 pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral).
Information
In the hybrid system, the engine auto-
matically 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 beingcharged
- Depending on the temperature con- dition of the hybrid battery
i
To avoid serious injury, turn off
hybrid system and be sure " "
indicator is off before working
under hood. Engine may start
unexpectedly.
WARNING

H23
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 compart-
ment. None of these sounds indicate
a problem. These are normal charac-
teristics 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.
When the hybrid system is turned
ON, the gasoline engine may acti-
vate or may not. In this situation, you
may feel a vibration. This does not
indicate a malfunction. When the
" " indicator illuminates, the
hybrid system is ready to begin driv-
ing. Even if the engine is off, you can
operate the vehicle as long as the
" " indicator is illuminated. The hybrid system contains many
electronic components. High volt-
age components, such as cables
and other parts, may emit electro-
magnetic waves. Even when the
electromagnetic cover blocks elec-
tromagnetic emissions, electro-
magnetic waves may have an
effect on electronic appliances.
When your vehicle is not used for
a long period of time, the hybrid
system will discharge. You need to
drive the vehicle several times a
month. We recommend driving at
least for 1 hour or 10 miles. When
the hybrid battery is discharged,
or when it is impossible to jump
start the vehicle, contact your
HYUNDAI dealer.

Check regenerative brakes
This warning message is displayed
when the brake performance is low
or the regenerative brake does not
work properly due to a failure in the
brake system.
In this case, it may take longer for the
brake pedal to operate and the brak-
ing distance may become longer.
Check Virtual Engine SoundSystem
This message is displayed when
there is a problem with the Virtual
Engine Sound System (VESS).
In this case, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Coasting guide (if equipped)
A chime will sound and the coasting
guide indicator will blink four times to
inform the driver when to take the
foot off from the accelerator by antic-
ipating a decelerating event* based
on the analysis of driving routes and
road conditions of the navigation. It
encourages the driver to remove foot
from the pedal and allow coasting
down the road with EV motor only.
This helps prevent unnecessary fuel
consumption and increases fuel effi-
ciency.

When the hybrid vehicle shuts
off
When the high voltage battery is dis-
charged, when the 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 followings:
1.Gradually reduce the vehiclespeed. Pull over your vehicle off
the road in a safe area.
2.Locate the shift lever in P (Park).
3. Turn ON the hazard warning flashers.
4.Turn OFF the Engine Start/Stop button, and try to start the hybrid
system, while depressing the
brake pedal and pressing the
Engine Start/Stop button. 5.When the hybrid system still does
not operate, refer to "EMERGENCY
STARTING" in the chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to "EMERGENCY
STARTING" in the chapter 6. When
the fuel level is low, do not attempt
to drive the vehicle only with the
battery power. The high voltage bat-
tery may be discharged, and the
hybrid system will turn OFF.
