Recommended Shift Speeds; Upshifts When Accelerating (Recommended For Best Fuel Economy); Hill Start Assist (Hsa) - Ford F-250 2012 Owner's Manual

Driving

Recommended shift speeds

Upshift according to the following chart:

Upshifts when accelerating (recommended for best fuel economy)

Shift from:
1 – 2
2 – 3
3 – 4
4 – 5
5 – 6
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, the SST will still automatically make some
downshifts if it has determined that you have not downshifted in time.
Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held
without shifting.

Hill start assist (HSA)

The hill start assist feature makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When the hill
start assist feature is active, the vehicle will remain stationary on the
slope for up to two seconds after you release the brake pedal. During
this time, you have time to move your foot from the brake to the
accelerator pedal and pull away. The brakes are released automatically
once the engine has developed sufficient drive to prevent the vehicle
from rolling down the slope. This is an advantage when pulling away on a
slope; for example from a car park ramp, traffic lights or when reversing
uphill into a parking space.
WARNING: The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and select first or reverse gear.
