Hill Start Assist - Tesla Model S Owner's Manual

Hill Start Assist

Hill Start Assist automatically engages the
brakes for approximately one second when on
a hill. This prevents Model S from rolling
during the time it takes for you to move your
foot from the brake pedal to the accelerator
pedal. Hill Start Assist engages the brakes
only if Model S is in Drive and facing uphill, or
in Reverse and facing downhill.
Warning: After approximately one
second, Hill Start Assist no longer brakes
your vehicle and it could roll. Therefore,
quickly move your foot from the brake
pedal to the accelerator pedal. Never rely
on Hill Start Assist to prevent Model S
from rolling for more than one second.
Failure to do so can result in a collision.
