Hill start assist
Hill start assist helpsyou when pulling awa yfor-
wards or in reverse on an uphill gradient. Hill
start assist automatically maintains the brake
pressure for about another second, after you
have taken you rfoot off the brake pedal. This
gives you enoug htime to move you rfoot from
the brake pedaltot he accelerator pedala nd
depress it before the vehicleb egins to roll.
GWARNING
After ashort time, hil lstart assist wil lnolon-
ger brake you rvehicl eand it coul droll away.
There is arisk of an accident and injury.
Therefore, quickly move you rfoot from the
brake pedaltot he accelerator pedal. Never
