Automatic Transmission - Aston Martin DB 9 2013 Manual

Starting From Cold
The Engine Control Module (ECM) automatically compensates for
cold or warm start conditions and makes appropriate adjustments to
the fuel and air mixture and ignition timing.
Stopping the Engine
Press the vehicle key fully in and release. The engine
will stop as the key returns to position 'I'. Withdraw
the vehicle key from the ignition control.
Maximum Engine Speed
The maximum safe engine speed is 6,850 rpm. If this speed is
exceeded, fuel supply to the engine is reduced. As the engine speed
reduces back to a safe level, fuel supply is progressively restored.

Automatic Transmission

The automatic transmission has two drive modes.
Auto Drive Mode
In auto drive mode gearshifts are made using the Park, Reverse,
Neutral and Drive (PRND) buttons mounted on the center stack.
While driving forward gearshifts are made automatically according to
various driving parameters, i.e. road speed, current selected gear and
accelerator demands. When the vehicle is stationary the transmission
will select first gear, ready to move off immediately when the
accelerator is pressed.
While in auto drive mode move to touchtronic mode at any time by
pulling back on either the upshift or downshift gearshift paddles,
mounted behind the steering wheel. As a paddle is pulled back a
gearshift will occur, this will be an upshift or downshift according to
which paddle is pulled.
Kick-Down
In auto drive mode kick-down is used in circumstances where rapid
acceleration is required, i.e. when overtaking. Kick-down operates
when the accelerator pedal is quickly and fully depressed, causing
the transmission to change down to the lowest gear possible to
achieve maximum acceleration. The gear engaged depends on the
road speed at the time of kick-down.
Touchtronic Mode
In touchtronic mode forward gears and Neutral are selected by using
the paddles located behind the steering wheel. Reverse and park
selected by using the PRND buttons.
While in touchtronic mode move to auto drive mode at any time by
pressing the DRIVE button.
Neutral can also be selected by pressing the NEUTRAL button.
