Left Buttons, top to bottom
- N The neutral button. Used to
select neutral gear and reverse.
- PC This is a confirm button to let the
engineers know that the driver has heard a request
(mainly used for pit confirming).
- Talk This latches the radio on for 30
seconds or alternatively the driver can press it again
to turn the radio off. A red LED light illuminates while
the radio is latched on.
- 10 This button has two
functionalities. Firstly I need to explain the
functionality of the driver defaults. The driver can
select a "driver default" from 1 to 77. These defaults
are used to enable/disable sensors/functions which are
in error or need to be modified (for instance activating
a fuel pump). When the MFS rotary is in the DEF position
the "10" and "1" buttons allow the driver to scroll
through driver default numbers. When the MFS is in any
position other than the DEF position the "+" and "-"
button allows the driver to scroll up/down the map
number assigned to that MFS position.
- SC When the safety car is deployed a
reference lap time (supplied by the FIA) is displayed on
the dash. The driver must remain above this lap time to
ensure he is not deemed to be driving too fast under the
safety car. The SC button allows the driver to turn off
this reference lap time once he has joined the train
behind the safety car.
- Drink Simply gives the driver a drink.
Right buttons, top to bottom
- Pit The driver presses this coming up
to the pit limiter line. The driver keeps the throttle
pedal pressed and the SECU controls the engine to keep
the car speed at the pit limit target (100km/h for
races). To slow down below the pit limit speed the
driver simply lifts off the throttle pedal
- Wing When pressed the rear wing flap
position is adjusted to the angle corresponding to the
- ACK This confirms any driver default
- 1+ The "1" button changes the index
numbers of the driver defaults. The "+" button scrolls
up the maps selected by the MFS rotary.
- Oil Activates transfer of oil from the
auxiliary tank to the main engine oil system
- BPF This enable the Bite-Point-Finder(BPF).
The BPF engages the clutch three times until the engine
speed drops allowing the bite point to be measured
- RED Button Spare button.
Rotaries (from top left, counter clockwise)
- MID This modifies the differential
torque demand as the driver comes off the brakes and
into the corner apex (MIDdle
of the corner).
- EXIT This modifies the differential
torque demand as the driver goes on the throttle pedal
exiting the corner (corner
- ENTRY This modifies the differential
torque demand under braking (corner
- MIX modifies the fuel/air ratio (MIXTURE).
Basically selects lean or rich maps
- EB modifies the engine torque demand
when braking (engine speed dependant)
- MFS multifunction switch as per last
year (any function can be allocated to this rotary)
- RPM The driver selects different
engine mapping from this rotary. Maps vary from maximum
performance, as used in qualifying, to maps used when
driver is behind a safety car.
- Clutch This modifies the clutch bite
- Tyres The driver must rotate this to
match the tyre fitted. When an intermediate or wet tyre
is selected the rain light is turned on. The tyre
circumference is also changed in the SECU to ensure the
measured speed is accurate. Changing tyre type can also
modify the many control strategies such as the speed of
a gear shift and the torque map.
