FORD 2015 F-150 - Manual (Page 199)

Note: There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed.
2. If the sensors detect that your vehicle
is on a slope, the system activates
automatically.
3. When you remove your foot from the
brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The
system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
When you switch the ignition on, the
system automatically turns on. You can
switch the system on or off in the
information display. See General
Information (page 105). The system
remains off until you switch the ignition off.
Note: For vehicles with a manual
transmission, the system can be switched
on or off.
Note: For vehicles with an automatic
transmission, the system cannot be
switched off.
