Checking the Brake Fluid
Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination. If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized HYUNDAI dealer.
Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
Brake fluid, which has been exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Do not use the wrong kind of brake fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.

Electric Vehicle
An electric vehicle is driven using a
battery and an electric motor. While
general vehicles use an internal
combustion engine and gasoline as
fuel, electric vehicles use electrical
energy that is charged inside the
high voltage battery. As a result,
electric vehicles are eco-friendly in
that they do not require fuel and do
not emit exhaust gases.
Characteristics of Electric
Vehicles
1. It is driven using the electricalenergy that is charged inside the
high voltage battery. This method
prevents air pollution since fuel,
like gasoline, is not required,
negating the emission of exhaust
gases.
2. A high performance motor is used in the vehicle as well. Compared
to standard, internal combustion
engine vehicles, engine noise and
vibrations are much more minimal
when driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This minimizes energy
loss and increases the distance to
empty.
4. When the battery charge is not sufficient, normal charge, quick
charge and trickle charge are
available. (Refer to "Charge Types
for Electric Vehicle" for details.)
Information
What does regenerative braking do?
It uses the electric motor when decel-
erating or braking which transforms
vehicle motion (kinetic energy) to elec-
trical energy to charge the high volt-
age batteries. (Torque is applied in the
opposite direction when decelerating
to generate braking force and electric
energy.)
Battery Information
• The vehicle is composed of a highvoltage 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 ( ) mode or the high
voltage battery is being charged.

On-Board Charger (OBC) : External device (low speed) to charge the high
voltage battery.
Inverter : Transforms direct current into alternate current to supply power
to the motor, and transforms alternate current into direct current to charge
the high voltage battery.
LDC : Transforms power from the high voltage battery to low voltage (12 V)
to supply power to the vehicle (DC-DC).

Main Components of Electric Vehicle
Motor : Uses electrical energy

like an engine in a standard vehi-
cle).
Reduction Gear : Delivers rota-
tional force of the motor to the tires
at appropriate speeds and torque.
High voltage battery (lithium-ion
polymer) : Stores and supplies
power necessary for the electric
vehicle to operate (12 V auxiliary
battery provides power to the vehi-
cle features such as lights and
wipers).

5. Check if the " " indicator isturned OFF on the instrument
cluster.
When the " " indicator is ON
and the gear is in a position other
than P (Park), the driver can acci-
dently depress the accelerator
pedal, causing the vehicle to move
unexpectedly.
Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestri-
ans to hear vehicle sound because
there is no sound while the Electric
Vehicle (EV) is operating.
If the vehicle is moving at lowspeed, the VESS will operate.
When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
Distance to Empty
The distance to empty is displayed
differently according to the selected
drive mode in the Drive Mode
Integrated Control System.
For more information, refer to "Drive
Mode Integrated Control System" in
chapter 5.
OAEEQ016055
The vehicle does not generate
a sound. Be aware of your
driving environment and drive
safely.
After you park the vehicle or
while you are waiting at a traf-
fic light, check whether there
are children or obstacles
around the vehicle.
Check if there is something
behind the vehicle when driv-
ing in reverse. Pedestrians
may not hear the sound of the
vehicle.

When this warning message is
displayed, do not accelerate or
start the vehicle suddenly.
Charge the battery immediately
when the high voltage battery
level is not enough.
Stop vehicle and check powersupply
This warning message is displayed
when a failure occurs in the power
supply system.
In this case, park the vehicle in a
safe location and recommend that
you tow your vehicle to the nearest
authorized HYUNDAI dealer and
have the vehicle inspected.
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 inspect-
ed by an authorized HYUNDAI dealer.
