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 16 km (10 miles).
When the hybrid battery is dis-
charged, or when it is impossible
to jump start the vehicle, contact
your HYUNDAI dealer.

Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates engine sounds for pedes-
trians to hear vehicle sound because
there is limited sound while electric
power is used.
What Does RegenerativeBraking Do?
It uses an electric motor when decel-
erating and braking and transforms
kinetic energy to electrical energy in
order to charge the high voltage bat-
tery.
Battery
The vehicle is composed of a high- voltage battery that drives the
motor and air-conditioner, and an
auxiliary battery (12 V) that drives
the lamps, wipers, and audio sys-tem.
The auxiliary battery is automati- cally charged when the vehicle is in
the ready ( ).
Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving conditionis fuel efficient or not.
When you start the hybrid
system with the shift lever in
P (Park), the “ ” indicatorilluminates on the instrument
cluster. The driver can drive
the vehicle, even when the
gasoline engine is off.
When you leave the vehicle,
you should turn OFF the vehi-
cle and place the shift lever in
P (Park). If you depress the
accelerator pedal by mistake,
or when the shift lever is not
in P (Park), the vehicle will
abruptly move, possibly
resulting in serious injury ordeath.

Shows that the vehicle is beingdriven in an Eco-friendly manner.
POWER : Shows that the vehicle is exceeding
the Eco-friendly range.
According to the hybrid systemgauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is driven using the electric motor or thegasoline engine is stopped.
- "EV" indicator OFF : Vehicle is driv- en using the gasoline engine.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 (State of
charge) gauge is near the "L (Low)"
level, have the vehicle checked by an
authorized HYUNDAI dealer.

This indicator illuminates :
When the vehicle is ready to be driven.
- ON : Normal driving is possible.
- OFF : Normal driving is not possible,
or a problem has occurred.
- Blinking : Limp home driving mode. When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, have your vehi-
cle inspected by an authorized
HYUNDAI dealer.

Check Hybrid system. Do notstart engine.
This warning message is displayed
when the hybrid battery power
(SOC) level is low. A warning chime
will sound until the problem is solved.
In this case, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Stop vehicle and check powersupply
This warning message is displayed
when a failure occurs in the powersupply system.
In this case, park the vehicle in a
safe location and tow your vehicle to
the nearest authorized HYUNDAI
dealer and have the vehicle inspect-ed.
Park with engine On to charge battery
This warning message is displayed
when the hybrid battery power
(SOC) level is low.
In this case, park the vehicle in a
safe location and wait until the hybrid
battery is charged.
You can increase the hybrid battery
charging rate by holding the acceler-

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 VirtualEngine 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 fuelconsumption and increases fuel effi-ciency

❈ Example of a deceleration event is
going down an extended hill, slow-
ing down approaching a toll booth,and approaching reduced speed
zones.

Press the Engine Start/Stop button and put the shift lever in P(Park). In the
User Settings Mode, select Driving Assist, Coasting Guide, and then On to
turn on the system. Cancel the selection of coasting guide to turn off the sys-
tem. For the explanation of the system, press and hold the [OK] button.

To activate the system, take the following procedures. Enter your destination
information on the navigation and select the driving route. Select the ECO
mode in the Integrated Driving Control System. Then, satisfy the following.
- The driving speed should be between 60 km/h (37 mph) and 160 km/h (99 mph). ❈The operating speed may vary due to difference between instrument clus-
ter and navigation effected by tire inflation level.

Information
Coasting guide is only a supplemental
system to assist with fuel-efficient driv-
ing. Thus, the operating conditions
may be different in accordance with
traffic/road conditions (i.e. driving in a
traffic jam, driving on a slope, driving
on a curve). Thus, take the actual driv-
ing conditions into consideration, such
as distances from the vehicles ahead/
behind, while referring to the coasting
guide system as guidance. Unplugging vehicle to start (Plug-in hybrid)
The message is displayed when you
start the engine without unplugging
the charging cable. Unplug the
charging cable, and then start the
vehicle.
Remaining time to fully chargethe battery (Plug-in hybrid)
The message is displayed to notifythe remaining time to fully charge the
battery.
