WARNING!

In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability.
؆ESC Off؆ mode is intended for off-highway
or off-road use only.

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 their foot off of 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 6% (approximate) grade or

greater 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.
