The system will activate automatically on any
slope that will cause significant vehicle
rollback.
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 will activate
automatically.
3. When you remove your foot from the
brake pedal, your vehicle will remain on
the slope without rolling away for about
two or three seconds. This hold time will
automatically be extended if you are in
the process of driving off.
4. Drive off in the normal manner. The
brakes will release automatically.
