Driving your vehicle
• The dual clutch transmission can
be thought of as an automatically
shifting manual transmission. It
gives the driving feel of a manual
transmission, yet provides the
ease of a fully automatic transmis-
sion.
• When D (Drive) is selected, the
transmission will automatically shift
through the gears similar to a con-
ventional automatic transmission.
Unlike a traditional automatic
transmission, the gear shifting can
sometimes be felt and heard as the
actuators engage the clutches and
the gears are selected.
• The dual clutch transmission incor-
porates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driv-
ing. But it differs from a conven-
tional automatic transmission
because it does not incorporate a
torque converter. Instead, the tran-
sition 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 engine 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 1,500 km (1000
miles), you may feel that the vehi-
cle may not be smooth when accel-
erating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.

• Always come to a complete stop
before shifting into D (Drive) or
R (Reverse).
• Do not put the shift lever in N
(Neutral) while driving.
DCT warning messages
This warning message is displayed
when vehicle is driven slowly on a
grade and the vehicle detects that
the brake pedal is not applied.
Steep grade
Driving up hills or on steep grades:
• To hold the vehicle on an incline
use the foot brake or the parking
brake.
• When in stop-and-go traffic on an
incline, allow a gap to form ahead
of you before moving the vehicle
forward. Then hold the vehicle on
the incline with the foot brake.
NOTICE
To reduce the risk of serious
injury or death:
•ALWAYS check the surround-
ing areas near your vehicle
for people, especially chil-
dren, 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 ignition
switch in the LOCK/OFF posi-
tion. Unexpected and sudden
vehicle movement can occur
if these precautions are not
followed.
•Do not use the engine brake
(shifting from a high gear to
lower gear) rapidly on slip-
pery roads. The vehicle may
slip causing an accident.
WARNING
OTLE055018
•To avoid damage to your
transmission, do not try to
accelerate in R (Reverse) or
any forward gear position with
the brakes applied.
•When stopped on a slope, do
not hold the vehicle with
accelerator pedal. Use the
brake pedal or the parking
brake.
CAUTION
Due to transmission failure, you
may not continue to drive and
the position indicator and the
position indicator (D, P) on the
instrument cluster will blink. We
recommend that you contact an
authorized HYUNDAI dealer and
have the system checked.
WARNING

5-18
Driving your vehicle
• If the vehicle is held or creeping
forward on an incline by applying
the accelerator pedal, the clutch
and transmission may overheat
which can result in damage. At this
time, a warning message will
appear on the LCD display.
• If the LCD warning is active, the
foot brake must be applied.
• Ignoring the warnings can lead to
damage to the transmission.
To hold the vehicle on a hill use
the foot brake or the parking
brake. If the vehicle is held by
applying the accelerator pedal on
a hill, the clutch and transmission
will be overheated resulting in
damage.
Transmission high temperature
• Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase exces-
sively.
• When the clutch temperatures are
too high, the "Transmission temp is
high! Stop safely" warning mes-
sage will appear on the LCD dis-
play, a chime will sound, and the
transmission shifting may not be
smooth.• If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park),
and allow the transmission to cool.
• If you ignore this warning, the driv-
ing condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness.
• When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
• When possible, drive the vehicle
smoothly.

Transmission overheated
• If the vehicle continues to be driv-
en and the clutch temperatures
reach the maximum temperature
limit, the "Trans Hot! Park with
engine on" warning will be dis-
played. When this occurs the clutch
is disabled until the clutch cools to
normal temperatures.
• The warning will display a time to
wait for the transmission to cool.
• If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park),
and allow the transmission to cool.• When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
• When possible, drive the vehicle
smoothly.
If any of the warning messages in the
LCD display continue to blink, for
your safety, we recommend that you
contact an authorized HYUNDAI
dealer and have the system checked.
Shift lever position
The indicator in the instrument clus-
ter displays the shift lever position
when the ignition switch is in the ON
position.
P (Park)
Always come to a complete stop
before shifting into P (Park).
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
If you have done all of the above
and still cannot shift the lever out of
P (Park), see "Shift-Lock Release"
in this chapter.
The shift lever must be in P (Park)
before turning the vehicle off.

R (Reverse)
Use this position to drive the vehicle
backward.
Always come to a complete stop
before shifting into or out of R
(Reverse); you may damage the
transmission if you shift into R
(Reverse) while the vehicle is in
motion.
N (Neutral)
The wheels and transmission are not
engaged.
D (Drive)
This is the normal driving position.
The transmission will automatically
shift through a 6-gear sequence, pro-
viding the best fuel economy and
power.
For extra power when passing anoth-
er vehicle or driving uphill, depress
the accelerator fully. The transmis-
sion will automatically downshift to
the next lower gear (or gears, as
appropriate).
If you drive the vehicle with the shift
lever in D (Drive), the vehicle will
automatically change to ECO mode.
The indicator will illuminate on
the instrument cluster.
When driving in ECO mode, the vehi-
cle improves fuel efficiency for eco-
friendly driving.
NOTICE
•Shifting into P (Park) while the
vehicle is in motion may
cause you to lose control of
the vehicle.
•After the vehicle has stopped,
always make sure the shift
lever is in P (Park), apply the
parking brake, and turn the
vehicle off.
•Do not use the P (Park) posi-
tion in place of the parking
brake.
•When parking on an incline,
place the shift lever in P (Park)
and apply the parking brake to
prevent the vehicle from
rolling downhill.
•For safety, always engage the
parking brake with the shift
lever in the P (Park) position
except for the case of emer-
gency parking.
