HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• Vehicle must be stopped.
• Vehicle must be on a 3% (manual transmission), 3.5%
(automated manual transmission), or 8% grade or
greater (automatic transmission) hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing 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.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
Towing With HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
