HSA Activation Criteria

~1min read

The following criteria must be met in order for HSA to activate:

• Vehicle must be stopped.

• Vehicle must be on a 6% (approximate) grade or greater hill.

• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle backing uphill is in REVERSE gear).

HSA will work in REVERSE and all forward gears when the activation criteria have been met. The system will not activate if the vehicle is placed in NEUTRAL or PARK.
