brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESC are in
the Partial Off mode. Refer to "Electronic Stability Con-
trol (ESC)" in this section for further information.

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 2.5% (manual transmission) or
7% grade or greater (automatic transmission) 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).
