Electronic Roll Mitigation (ERM)

This system anticipates the potential for wheel lift by

monitoring the driver’s steering wheel input and the

speed of the vehicle. When ERM determines that the rate

of change of the steering wheel angle and vehicle’s speed

are sufficient to potentially cause wheel lift, it then

applies the appropriate brake and may also reduce

engine power to lessen the chance that wheel lift will

occur. ERM will only intervene during very severe or

evasive driving maneuvers. ERM can only reduce the

chance of wheel lift occurring during severe or evasive

driving maneuvers. It cannot prevent wheel lift due to

other factors, such as road conditions, leaving the road-

way, or striking objects or other vehicles.
NOTE:

ERM is disabled anytime the ESC is in “Full Off”

mode. Refer to Electronic Stability Control (ESC) for a

complete explanation of the available ESC modes.

WARNING!

Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. Electronic Roll
Mitigation (ERM) cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous manner,
which could jeopardize the user’s safety or the safety
of others.

Hill Start Assist (HSA)

The HSA system is designed to help the driver accelerate

the vehicle from a complete stop while on an incline. If

the driver releases the brake while stopped on an incline,

HSA will continue to hold the brake pressure for a short

period. If the driver does not apply the throttle before this
