Hill Start Assist - Aston Martin One-77 2010 Owner's Manual

When Sport mode is ON while in:
Auto Drive -
Upshifts and downshifts occur at higher
engine speeds to provide a sportier drive.
If sport mode is selected while in auto drive sixth
gear a downshift to fifth gear will occur (this will not
happen if cruise control is ON) and sixth gear will be
inhibited until sport mode is set to OFF.
Paddle Shift -
Automatic upshifts are prevented, the
upshift paddle must be pulled back and released to
make an upshift (downshifts will occur automatically if
the engine speed lowers to its minimum operating
limits).
To maintain speed and smoothness while driving in
paddle shift sport mode, the current gear, shown in the
GPID, will flash red at the optimum time to make an
upshift.

Hill Start Assist

The hill start assist function gives assistance and safety
for driving off on an incline. If the foot brake is applied
for a time when the vehicle is stationary on an incline,
when moving off, the brake pressure is retained for a
brief moment when you change from the brake to the
accelerator pedal. This stops the vehicle from rolling
back without the need to apply the park brake.
