Transmission ranges
The indicator in the instrument cluster
displays the gear position when the
ignition switch is in the ON position.
WARNING
To reduce the risk of serious injury or
death: • ALWAYS check the surrounding
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 gear is in
the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• If equipped, do not use the engine
brake (shifting from a high gear to
lower gear using the paddle shifters)
rapidly on slippery roads.
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.
The gear must be in P (Park) before
turning the engine off.
WARNING
• 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 gear is in P (Park),
apply the parking brake, and turn
the engine off.
• Do not use the P (Park) position in
place of the parking brake.
R (Reverse)
Use this position to drive the vehicle
backward.
NOTICE
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.
When the vehicle is stopped in
R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear is shifted to P (Park)
position automatically.
However when the vehicle moves
in R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear may be not shifted
to P (Park) position automatically for
protecting the automatic transmission.
N (Neutral)
The wheels and transmission are not engaged.
Use N (Neutral) if you need to restart a
stalled engine, or if it is necessary to stop
with the engine ON. Shift into P (Park)
if you need to leave your vehicle for any
reason.
Always depress the brake pedal when
you are shifting from N (Neutral) to
another gear.
WARNING
Do not shift into gear unless your foot is
firmly on the brake pedal. Shifting into
gear when the engine is running at high
speed can cause the vehicle to move
very rapidly. You could lose control of
the vehicle and hit people or objects.

6-15
D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 8-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition switch in the ON position.
3. Depress the brake pedal and push the R (Reverse) or D (Drive) button. Stay in N (Neutral) position when engine is Off
ODN8069006
ODN8069008
If you want to keep the N (Neutral)
position after the engine is OFF, do the
following.
1. Deactivate the AUTO HOLD and release the parking brake when the
ignition switch is ON.
2. Start the engine. Push the N (neutral) button while depressing the brake
pedal. If the message ("Press and
hold OK button to stay in Neutral
when vehicle is OFF") appears on the
cluster LCD display, press and hold
the OK button on the steering wheel
for more than 1 second.
3. When the message ("Vehicle will stay in (N). Change gear to cancel")
appears on the cluster LCD display,
turn off the engine.
In this situation, if you unfasten the
driver's seat belt and open the driver's
door within 3 minutes, the gear stays in
the N (Neutral) position and the ignition
switch is turned off.

Dual clutch transmission operation
The dual clutch transmission has eight forward speeds and one reverse speed.
The individual speeds are selected automatically when the shift button is in the D
(Drive) position.

•
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 transmission.
• When D (Drive) is selected, the
transmission will automatically
shift through the gears similar to a
conventional 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
incorporates a wet-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driving.
But it differs from a conventional
automatic transmission because
it does not incorporate a torque
converter. 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 vibration can
be felt as the transmission shaft speed
is matched with the engine shaft
speed. This is a normal condition of
the dual clutch transmission.
• The wet-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 launching the vehicle
from a stop or when traveling at low,
stop-and-go vehicle 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 correct gear. This is a normal condition.
• 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 accelerator
pedal quickly, you may feel engine
braking before the transmission
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/button 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 vehicle may not
be smooth when accelerating at low
speed. During this break-in period, the
shift quality and performance of your
new vehicle is continuously optimized.

While Driving

•
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.
