Regenerative braking level indi-
cator
While using the regenerative brakes,
you may select the regenerative
braking level from 0 to 3 by pulling
the paddle shifter.For more details, refer to "Paddle
shift" in chapter 5.
Warning and Indicator Lights
Information
Make sure that all warning lights are
OFF after starting the engine. If any
light is still ON, this indicates a situa-
tion that needs attention.
Ready Indicator
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 : Emergency driving.
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.

When the brake fluid level in the
reservoir is low.
- If the warning light illuminates
with the parking brake released, it
indicates the brake fluid level in
the reservoir is low.
When the regenerative brake does
not operate.
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check
the brake fluid level immediately
and add fluid as required (For
more details, refer to "Brake
Fluid" in chapter 7). After adding
brake fluid, check all brake com-
ponents for fluid leaks. If a brake
fluid leak is found, or if the warning
light remains on, or if the brakes
do not operate properly, do not
drive the vehicle. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure is
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
In this case, have the vehicle
inspected by an authorized
HYUNDAI dealer.WARNING

Convenient features of your vehicle
Regenerative Brake
Warning Light
This warning light illuminates :
When you place the Engine Start/
Stop button to the ON position.
- It illuminates for approximately 3
seconds.
When the regenerative brake does
not operate and the brake does not
perform well. This causes the Brake
Warning light and Regenerative
Brake Warning Light to illuminate
simultaneously.
In this case, drive safely and have
your vehicle inspected by an author-
ized HYUNDAI dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase.
Anti-lock Brake System
(ABS) Warning Light
This warning light illuminates:
When you place the Engine Start/
Stop button to the ON position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a malfunction with
the ABS (The normal braking sys-
tem will still be operational without
the assistance of the anti-lock
brake system).
In this case, have the vehicle inspect-
ed by an authorized HYUNDAI deal-
er.
Electronic Brake Force
Distribution (EBD)
System Warning Light
These two warning lights illuminate
at the same time while driving:
When the ABS and regular brake
system may not work normally.
In this case, have the vehicle inspect-
ed by an authorized HYUNDAI deal-
er.
Electronic Brake Force
Distribution (EBD) System
Warning Light
When both ABS and Parking
Brake & Brake Fluid Warning
Lights are on, the brake system
will not work normally and you
may experience an unexpected
and dangerous situation during
sudden braking.

does not work properly.
If this warning message is displayed,
have the vehicle inspected by an
authorized HYUNDAI dealer.
Check Virtual Engine Sound
System
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.

Regen B mode
The paddle shifter is used to adjust
the regenerative braking level from 0
to 3 when the vehicle is in ECO
mode.
Left side (-): Increases the regen-
erative braking level and decelera-
tion.
Right side (+): Decreases the
regenerative braking level and
deceleration.
Information
• The Regen B function starts from
level 0 when starting your vehicle
and the system works only in D
(Drive).
• The Regen B function is cancelled
when the vehicle is shifted to the P
(Park), R (Reverse), N (Neutral) and
Sport mode.
• The Regen B function is cancelled
while ABS (Anti-lock Braking
System) and ESC (Electronic
Stability Control) is operating.
• Deceleration differences occur even
in the same system level according
to driving speeds (You may recog-
nize significant deceleration differ-
ences during city driving but you
may not feel differences while high
speed driving.)
Information
The paddle shifter does not operate
when:
• Both paddle shifters are pulled at
the same time.
• The vehicle is decelerating by
depressing the brake pedal.
• The Cruise Control system or Smart
Cruise Control system is activated.

Operating the paddle shifter will
not enable the vehicle to come
to a complete stop. Depress the
brake pedal to stop the vehicle
completely.
CAUTION
The Regen B function may not
operate depending on the
motor's chargeable state (over
charged, high temperature or
low temperature). Always pay
attention to road and driving
conditions, while driving. If nec-
essary, depress the brake pedal
to reduce your driving speed.

The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric 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 off 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
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.
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.
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 being
charged
- Depending on the temperature con-
dition of the hybrid battery
