VEHICLE DATA COLLECTION

AND EVENT DATA

RECORDERS

This vehicle is equipped with an event

data recorder (EDR). The main purpose

of an EDR is to record, in certain crash

or near crash-like situations, such as

an air bag deployment or hitting a

road obstacle, data that will assist in

understanding how a vehicle’s systems

performed. The EDR is designed to

record data related to vehicle dynamics

and safety systems for a short period of

time, typically 30 seconds or less. The

EDR in this vehicle is designed to record

such data as:

•

How various systems in your vehicle

were operating;

•

Whether or not the driver and

passenger safety belts were buckled/

fastened;

•

How far (if at all) the driver was

depressing the accelerator and/or

brake pedal; and,

•

How fast the vehicle was traveling.

These data can help provide a better

understanding of the circumstances in

which crashes and injuries occur. NOTE:

EDR data is recorded by your vehicle

only if a non-trivial crash situation

occurs; no data are recorded by the EDR

under normal driving conditions and

no personal data (for example, name,

gender, age, and crash location) are

recorded. However, other parties, such

as law enforcement, could combine the

EDR data with the type of personally

identifying data routinely acquired

during a crash investigation.
To read data recorded by an EDR,

special equipment is required, and

access to the vehicle or the EDR is

needed. In addition to the vehicle

manufacturer, other parties, such as

law enforcement, that have the special

equipment, can read the information if

they have access to the vehicle or the

EDR.

HEV (HYBRID ELECTRIC VEHICLE) SYSTEM

The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the

electric motor for power. The electric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between

the engine and the electric motor or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the

electric motor with the HEV battery.
The HEV battery charge must be maintained, so at times the engine will come on even

at idle to act as a generator. Charging also occurs when decelerating or by regenerative

braking.

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 lever is in P (Park).

With the shift lever in N (Neutral), you

cannot start the vehicle.

4. Depress the brake pedal.
5. Turn on the vehicle. 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 lever in N (Neutral), the hybrid

system cannot generate electricity.

The hybrid battery cannot recharge

with the shift lever 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

1-11

When the hybrid system is turned ON,

the gasoline engine may run 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

driving. Even if the engine is off, you can

operate the vehicle as long as the

“

” indicator is illuminated.

NOTICE

The hybrid system contains many

electronic components. High voltage

components, such as cables and other

parts, may emit electromagnetic waves.

Even when the electromagnetic cover

blocks electromagnetic emissions,

electromagnetic waves may have an

effect on electronic devices. 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. Have driving at least

for 1 hour or 10 miles (16 km). When the

hybrid battery is discharged, or when it

is impossible to jump start the vehicle,

contact your authorized HYUNDAI

dealer.

WARNING

•

When you start the hybrid system

with the shift lever in P (Park), the

“

” indicator illuminates 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 hybrid system

or locate the shift lever in P (Park).

When 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 or death.

Virtual Engine Sound System (VESS)

The Virtual Engine Sound System

generates engine sound for pedestrians

to hear vehicle sound because there is

limited sound while motor power is used.

•

If the gear shifts out of P (Park) after

start-up, the VESS sound is output.

•

When the gear is shifted to R

(Reverse), an additional warning

sound will be heard.

What does regenerative braking do?

It uses an electric motor when

decelerating and when braking. It

transforms kinetic energy to electrical

energy in order to charge the high

voltage battery.

Battery

•

The vehicle is composed of a high

voltage battery that drives the motor

and air conditioner, and an integrated

12 V lithium ion battery with the HEV

battery that drives the lamps, wipers,

and audio system.

•

The integrated 12 V battery is

automatically charged when the

vehicle is in the ready (

) mode.
