HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• Vehicle must be stopped
• Vehicle must be on an 8% (approximately) or greater
incline (approximately 3% for manual transmission
equipped vehicles)
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer where the system
will not activate and slight rolling may occur, which

could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
The system will only work if the intended direction of the
vehicle and vehicle gear match. For example, if the
intended direction is forward up a hill and the vehicle is
in DRIVE (automatic transmission equipped vehicle),
and the activation criteria are met, HSA will activate.
HSA On Automatic Transmission Vehicles
The system will work in REVERSE, and all forward gears
on vehicles equipped with an automatic transmission.
The system will not activate if the vehicle is placed in
NEUTRAL.
