H2
Hyundai Hybrid Electric Vehicle (HEV)
uses a gasoline engine and an electric
motor for power. The electric motor is
run from a 280V high voltage HEV bat-
tery.
HEV computer decides according to
drive condition when to use engine
from when to use the electric motor or
even both at times.
Fuel is saved when the engine is not
running at idle at times or the vehicle
is driven by the electric motor from
the HEV battery.
The charge of the HEV battery has to
be maintained so at times the engine
becomes a generator which includes
when stopped at idle. Charging also
occurs when decelerating or by
regenerative braking.Display of Hybrid system
Many displays provide information about
the hybrid system, such as, ECO level
and ECO score.
Through the ECO LEVEL, the driver under-
stands the situation of economical driving.
If the driver drives the vehicle with eco-
nomical driving, the ECO LEVEL rises.
And it means the CO2 emission reduction.
In TOTAL ECO SCORE, when you get the
maximum step of ECO LEVEL, ECO sys-
tem adds the score and saves the score.Eco level display flower mode.1
When the hybrid vehicle is started, the
ECO level step 4 is displayed. If you drive
economically, ECO level will be upgrad-
ed.
- However, if you do not drive economical-
ly, the ECO level will be down-graded.

Eco level display flower mode.2
In the “vehicle setting”, if you change the
animation mode to "ON", the dynamic
image will be activated.
- This provides the driver with the
dynamic ECO mode.Total eco score display
If your ECO level achieves the top step,
your ECO score automatically saves 1
point.
In the “vehicle setting”, if you change the
animation mode to “ON”, the dynamic
image will be on.SOC Gauge (State of charge)
This State of Charge(SOC) gauge indi-
cates the left Hybrid battery power. If the
SOC is near L level, the vehicle automat-
ically operates the engine to charge the
battery. However, if the service indicator
and MIL(Malfunction indicator lamp) turn
on when the State of Charge(SOC) is
near L(Low), the vehicle should be
towed. Refer to the chapter 6.

Starting the engine
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 the P(Park)
position. In N(Neutral) position, you
can not start the vehicle.
4. Depress the brake pedal.
5. Press the engine start/stop button.
6. In extremely cold weather or after the
vehicle has not been operated for sev-
eral days, let the engine warm up with-
out depressing the accelerator.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.

if it is far away from you, the engine
may not start.

in the ACC or ON position, if any door
is open, the system checks for the
smart key. If the smart key is not in
the vehicle, the warning, "Key is not
in vehicle" will come on, and if all
doors are closed, the chime will also
sound for about 5 seconds. The indi-
cator will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC position
or if the vehicle engine is on.IF the starting procedure is followed,
the "READY" symbol on the instru-
ment cluster will turn on. For more
details, Please check chapter 5.
ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a mod-
erate rate and maintain a steady cruis-
ing speed. Don't make "jack-rabbit"
starts. Don't race between stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary 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 runs in "N" position,
the hybrid system can not generate
electricity. The hybrid battery cannot
recharge in "N" position. Please check
chapter 5.
✽ ✽
NOTICE
In the hybrid system, the engine auto-
matically runs and stops. If the hybrid
system operates, the "READY" symbol
is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is charged
- Depending on the temperature condi-
tion of the hybrid battery

H11
The special features of hybrid
vehicle.
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 a
sound. when you apply the brake pedal,
you may hear a sound from the regener-
ative brake system. When the hybrid sys-
tem 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 com-
partment. None of these sounds indicate
a problem. They are characteristics of
hybrid vehicles.
If any of following occur, it's not a unnor-
mal condition even if you may 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
engine may run or not. In this situation,
you may feel a vibration. This does not
indicate a malfunction. If the "READY"
symbol is turned on, the hybrid system
starts. Even if the engine is off, you can
operate the vehicle.
WARNING
The hybrid system contains many
electronic components. High volt-
age components like cables and
other parts may emit electromag-
netic waves. Even if the electro-
magnetic cover blocks electromag-
netic emissions, electromagnetic
waves may have an effect on elec-
tronic appliances. If you park the
vehicle for a long time, the hybrid
system will discharge. You need to
drive the vehicle several times per
month. We recommend driving at
least 1 hour or 10 miles when you
drive the vehicle. If the hybrid bat-
tery is discharged and if it is impos-
sible to jump start the vehicle con-
tact your Hyundai dealer.
WARNING
When you start the hybrid system
in the "P" transmission position,
the "READY" symbol is illuminat-
ed in the cluster. The driver can
drive the vehicle even if the
engine is stopped.
When you leave the vehicle, you
should turn off the hybrid system
or shift into the "P" position. If
you depress the accelerator
pedal by mistake and the vehicle
is not in the "P" position, the
vehicle will move abruptly. This
may result in serious injury or
death.

Introduction

"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
HYUNDAI recommends that customers
do not use fuel with an ethanol content
exceeding 10 percent.Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Gasolines for cleaner air
To help contribute to cleaner air,
HYUNDAI recommends that you use
good quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run clean-
er and enhance performance of the
Emission Control System.
