But it differs from a conventional
automatic transmission because it
does not incorporate a torque con-
verter. Instead, the transition from
one gear to the next is managed by
clutch slip, especially at lower
speeds.
As a result, shifts are sometimes
more noticeable, and a light vibra-
tion can be felt as the transmission
shaft speed is matched with the
engine shaft speed. This is a nor-
mal condition of the dual clutch
transmission.
The dry-type clutch transfers
torque more directly and provides
a direct-drive feeling which may
feel different from a conventional
automatic transmission. This may
be more noticeable when launch-
ing the vehicle from a stop or when
traveling at low, stop-and-go vehi-
cle speeds.
When rapidly accelerating from a
lower vehicle speed, the engine
rpm may increase dramatically as
a result of clutch slip as the dual
clutch transmission selects the cor-
rect gear. This is a normal condi-
tion. When accelerating from a stop on
an incline, press the accelerator
smoothly and gradually to avoid
any shudder feeling or jerkiness.
When traveling at a lower vehicle
speed, if you release the accelera-
tor pedal quickly, you may feel
engine braking before the trans-
mission changes gears. This
engine braking feeling is similar to
operating a manual transmission at
low speed.
When driving downhill, you may
wish to move the gear shift lever to
Manual Shift mode and downshift
to a lower gear in order to control
your speed without using the brake
pedal excessively.
When you turn the vehicle on and
off, you may hear clicking sounds
as the system goes through a self-
test. This is a normal sound for the
dual clutch transmission.
During the first 1000 miles (1,500
km), you may feel that the vehicle
may not be smooth when acceler-
ating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.To reduce the risk of serious
injury or death:
ALWAYS check the surround-
ing areas near your vehicle for
people, especially children,
before shifting a vehicle into
D (Drive) or R (Reverse).
Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, then set the parking
brake, and place the Engine
Start/Stop button in the OFF
position. Unexpected and
sudden vehicle movement
can occur if these precautions
are not followed.
Do not use aggressive engine
braking (shifting from a high-
er gear to a lower gear) on
slippery roads. This could
cause the tires to slip and may
result in an accident.

Do not apply the accelerator
pedal while the parking brake is
engaged. If you depress the
accelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
brake may occur.
Driving with the parking brake
on can overheat the braking sys-
tem and cause premature wear
or damage to brake parts. Make
sure the parking brake is
released and the Brake Warning
Light is off before driving.Check the Parking
Brake Warning Light
by placing the Engine
Start/Stop button to
the ON position (vehi-
cle not in the ready
( ) mode).
This light will be illuminated when the
parking brake is applied with the
Engine Start/Stop button in the
START or ON position.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while the vehicle is in the
ready ( ) mode, there may be a
malfunction in the brake system.
Immediate attention is necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.
Electronic Parking Brake
(EPB) (if equipped)
Applying the parking brake
To apply EPB (Electronic Parking
Brake):
1. Depress the brake pedal.
2. Pull up the EPB switch.
Make sure the Parking Brake Warning
Light ( ) comes on.

Information
• For your safety, you can engage
EPB even though the ignition switch
is in the OFF position (only if bat-
tery power is available), but you
cannot release it.
• For your safety, depress the brake
pedal and release the parking brake
manually with the EPB switch when
you drive downhill or when backing
up the vehicle.
If the parking brake warning
light is still on even though EPB
has been released, we recom-
mend that the system be
checked by an authorized
HYUNDAI dealer.
Do not drive your vehicle with
the EPB applied. It may cause
excessive brake pad and brake
rotor wear.
EPB (Electronic Parking Brake)
may be automatically applied
when:
It is requested by other systems
The driver turns the vehicle off
while Auto Hold is operating.
Warning messages
To release EPB, fasten seatbelt,
close door, hood and liftgate
When you try to drive with EPB
applied, a warning will sound and a
message will appear.
If the driver's seat belt is unfas-
tened and the engine hood or lift-
gate is opened, a warning will
sound and a message will appear.
When there is a problem with the
vehicle, a warning may sound and
a message may appear.
If the situation occurs, depress the
brake pedal and release EPB by
pressing the EPB switch.

surrounding area near your vehicle
and release the parking brake man-
ually with the EPB switch.
• While operating Auto Hold, you may
hear mechanical noise. However, it is
normal operating noise.

Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
i
When you drive on a road hav-
ing poor traction, such as an icy
road, and apply your brakes
continuously, the ABS will be
active continuously and the
ABS warning light ( ) may
illuminate. Pull your car over to
a safe place and turn the vehicle
off.
Restart the vehicle. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
CAUTION
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.

Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and/or message illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the Engine Start/Stop button is
placed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the vehicle, ESC will auto-
matically turn on again.
Indicator lights
When the Engine Start/Stop button
is placed to the ON position, the ESC
indicator light illuminates, then goes
off if the ESC system is operating
normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.
The ESC OFF indicator light comes
on when ESC is turned off.Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.NOTICE
■ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)When ESC is blinking, this indi-
cates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off while the ESC indicator
light is blinking or you may lose
