HSA Off
If you wish to turn off the HSA system, follow this

transmission) or NEUTRAL with clutch out (manual
transmission) with wheels straight. Apply parking brake
on manual transmission vehicle.
2. Start the engine.
3. With the engine running, the brake applied, and the
clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESC OFF switch four times within
twenty seconds.
5. Rotate the steering wheel 360° clockwise (180° clock-
wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the "ESC
Activation/Malfunction Indicator Light" will blink
several times to confirm HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.

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 applies the appropriate
brake and may reduce engine power to lessen the chance
that wheel lift will occur. ERM will only intervene during
very severe or evasive driving maneuvers.
