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.

NOTE:

When the ESC is switched OFF, a feature of the

system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential. If
one wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that is
not spinning. To improve the vehicle’s traction when
driving with tire chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the “Partial
Off” mode by momentarily pressing the “ESC Off” switch.

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.
