the Engine Start/Stop button will illu-
minate and will go off 30 seconds
after the door is closed.
OAE056001R
To turn the hybrid system 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 hybrid system
without depressing the brake
pedal by pressing the Engine
Start/Stop button with the shift
lever in the N (Neutral) position.
WARNING
NEVER press the Engine
Start/Stop button whilst the
vehicle is in motion except in
an emergency. This will result
in the hybrid system turning
off and loss of power assist
for the steering and brake
systems. This may lead to
loss of directional 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 position, and
take the Smart Key with you.
Unexpected vehicle movement
may occur if these precautions
are not followed.

Starting the hybrid system Information
• The vehicle will start by pressing theEngine Start/Stop button, only when
the smart key is in the vehicle.
• Even if the smart key is in the vehi- cle, and when it is far away from the
driver, the hybrid system may not
start.
• When the Engine Start/Stop button is in the ACC or ON position, any
door is open, the system checks for
the smart key. When the smart key
is not in the vehicle, the " " indi-
cator will blink and the warning
"Key not in vehicle" will come on.
When 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
hybrid system is ON. 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.
i
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 which
can lead to an accident.

Information
• Do not wait for the engine to warmup whilst the vehicle remains sta-
tionary.
Start driving at moderate engine
speeds. Steep accelerating and
decelerating should be avoided.
• Always start the vehicle with your foot on the brake pedal. Do not
depress the accelerator whilst start-
ing the vehicle. Do not race the
engine whilst warming it up.
• If ambient temperature is low, the " " indicator may remain illumi-
nated longer than the normal amount
of time. To prevent damage to the vehicle:
If the " " indicator turns off
whilst you are in motion, do not
attempt to move the shift lever
to the P (Park) position.
Do not push or tow your vehicle to start the vehicle. To prevent damage to the vehicle:
Do not press the Engine Start/Stop
button for more than 10 seconds
except when the stop lamp fuse is
blown.
When the stop lamp fuse is blown,
you cannot normally start the
hybrid system. Replace the fuse
with a new one. If you are not able
to replace the fuse, you can start
the vehicle by pressing and hold-
ing the Engine Start/Stop button
for 10 seconds with the Engine
Start/Stop button in the ACC posi-

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 whilst
driving. But it differs from a con-
ventional 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.

The shift lever can freely operate. Depress the brake pedal and press the shift button whilst moving the shift lever.
Press the shift button whilst moving the shift lever.
Manual shift mode
Dual clutch transmission operation
The dual clutch transmission has six forward speeds and one reverse speed.
The individual speeds are selected automatically in the D (Drive) position.
❈ To move the shift lever from/to P (Parking) or between R (Reverse) and D (Drive), you must
depress the brake pedal for the vehicle to stand still.

5-16
Driving your vehicleAs 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
travelling 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 travelling 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 1000 miles (1500km), you may feel that the
vehicle may not be smooth when
accelerating at low speed. During
this break-in period, the shift quali-
ty and performance of your new
vehicle is continuously optimised. 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 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.
