Driving your vehicle
To reduce risk of serious injury
or death, NEVER allow children
or any person who is unfamiliar
with the vehicle to touch the
Engine Start/Stop button or
related parts. Unexpected and
sudden vehicle movement can
occur.
WARNING
OAE056001
NEVER press the Engine
Start/Stop button while the
vehicle is in motion except in
an emergency. This will result
in the engine turning off and
loss of power assist for the
steering and brake systems. (Continued)
WARNING
To turn the vehicle off in an
emergency:
Press and hold the Engine
Start/Stop button for more than
two seconds OR rapidly press
and release the Engine Start/
Stop button three times (within
three seconds).
If the vehicle is still moving, you
can restart the engine without
depressing the brake pedal by
pressing the Engine Start/Stop
button with the shift lever in the
N (Neutral) position.
WARNING (Continued)This may lead to loss of direc-
tional control and braking
function, which could cause
an accident.
Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, set the parking
brake, press the Engine Start/
Stop button to the OFF posi-
tion, and take the Smart Key
with you. Unexpected vehicle
movement may occur if these
precautions are not followed.
NEVER reach through the
steering wheel for the Engine
Start/Stop button or any other
control while the vehicle is in
motion. The presence of your
hand or arm in this area may
cause a loss of vehicle control
resulting in an accident.

Starting the VehicleInformation
• The vehicle will start by pressing the
Engine Start/Stop button, only when
the smart key is in the vehicle.
• Even if the smart key is in the vehi- cle, if it is far away from the driver,
the vehicle may not start.
• When the Engine Start/Stop button is in the ACC or ON position, if any
door is open, the system checks for
the smart key. If the smart key is not
in the vehicle, the " " indicator
will blink and the warning "Key not
in vehicle" will come on and if all
doors are closed, the chime will also
sound for about 5 seconds. Keep the
smart key in the vehicle when in the
ACC position or if the vehicle is in
the ready ( ) mode. 1. Always carry the smart key with
you.
2. Make sure the parking brake is applied.
3. Make sure the shift lever is in P (Park).
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the vehicle starts, the " "
indicator will come on.
Information
• Do not wait for the engine to warmup while the vehicle remains station-
ary. Start driving at moderate
engine speeds. (Aggressive accelerat-
ing and decelerating should be
avoided.)
• Always start the vehicle with your foot on the brake pedal. Do not
depress the accelerator while start-
ing the vehicle. Do not rev the
engine while warming it up.

Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes, such as
high heels, ski boots, sandals,
flip-flops, etc., may interfere
with your ability to use the
brake and accelerator pedals.
Do not start the vehicle with the
accelerator pedal depressed.
The vehicle can move and lead
to an accident.
Wait until the engine rpm is
normal. The vehicle may sud-
denly move if the brake pedal
is released when the rpm is
high.
WARNING

5-10
Driving your vehicle
To prevent damage to the vehicle:
If the " " indicator turns off while you are in motion, do not
attempt to shift to the P (Park)
position.
If traffic and road conditions
permit, you may put the shift
lever in the N (Neutral) position
while the vehicle is still moving
and press the Engine Start/Stop
button in an attempt to restart
the engine.
Do not push or tow your vehicle to start the vehicle. To prevent damage to the vehicle:
When the stop lamp switch fuse is
blown, you can't start the engine
normally. Replace the fuse with a
new one. If you are not able to
replace the fuse, you can start the
vehicle by pressing and holding
the Engine Start/Stop button for
10 seconds with the Engine Start/
Stop button in the ACC position.
Do not press the Engine Start/Stop
button for more than 10 seconds
except when the stop
lamp switch
fuse is blown.
For your safety always depress
the brake pedal before starting the
vehicle.
Information
If the smart key battery is weak or the
smart key does not work correctly,
you can start the engine by pressing
the Engine Start/Stop button with the
smart key in the direction of the pic-
ture above.

Dual Clutch Transmission
Operation
The dual clutch transmission has six
forward speeds and one reverse
speed.
The individual speeds are selected
automatically when the shift lever is
in the D (Drive) position.
The dual clutch transmission canbe 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 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.
