Driving your vehicle
6-24
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 1000 miles (1,500km),
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.
