Hill Start Assist (HSA)

The HSA system is designed to assist the driver when

starting a vehicle from a stop on a hill. HSA will maintain

the level of brake pressure the driver applied for a short

period of time after the driver takes his foot off the brake

pedal. If the driver does not apply the throttle during this

short period of time, the system will release brake

pressure and the vehicle will roll down the hill. The

system will release brake pressure in proportion to the

amount of throttle applied as the vehicle starts to move in

the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to

activate:

• Vehicle must be stopped.
• Vehicle must be on a 5% grade or greater hill.

• Gear selection matches vehicle uphill direction (i.e.,

vehicle in NEUTRAL (manual transmission), vehicle

facing uphill is in forward gear; vehicle backing uphill

is in REVERSE gear).

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.

Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be done

using the Customer Programmable Features in the Elec-

tronic Vehicle Information Center (EVIC). Refer to “Elec-

tronic Vehicle Information Center (EVIC)” in “Understand-

ing Your Instrument Panel” for further information.
