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!
•If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there may
not be enough brake pressure to hold both the
vehicle and the trailer on a hill when the brake
pedal is released. In order to avoid rolling down
an incline while resuming acceleration, manually
activate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake pedal.
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
•Failure to follow these warnings can result in an
accident or serious personal injury.
Disabling and Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
For vehicles equipped with the Electronic Vehicle Infor-
mation Center (EVIC), refer to “Hill Start Assist,” under
Personal Settings (Customer Programmable Features),”
under “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.
For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within
90 seconds.
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
