"Sport Plus" mode activated:
In "Sport Plus" mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with "Sport" mode.
f Please see the chapter "SPORT MODE" on
Page 61.
Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evasive action due to the
rapid acceleration that this technology
permits.
f Launch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
f Use Launch Control only if conditions permit it
to be applied in a safe manner.
f Do not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving.
Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the
engine has reached operating temperature.
– "Sport Plus" mode must be switched on (light-
emitting diode in button is on and "SPORT
PLUS" is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully
(kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
"Launch Control active" is displayed on the
on-board computer.
3. Release the brake within a few seconds.
Remaining stationary for a long time with
"Launch Control active" can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced and the "Launch Control
active" process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily from automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering
built-up areas.
– Shifting down on downward slopes
(engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler-
ation) and overrunning,
– when the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless
cornering or overrunning),
– after driving off.
