536 STARTING AND OPERATING

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 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 roadway, or striking objects

or other vehicles.

NOTE: ERM is disabled anytime the ESC is in "Full Off"

mode (if equipped). Refer to "Electronic Stability Control

(ESC)" in this section for a complete explanation of the

available ESC modes.

Many factors, such as vehicle loading, road condi-

tions and driving conditions, influence the chance

that wheel lift or rollover may occur. ERM cannot

prevent all wheel lift or roll overs, 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 reck-

less or dangerous manner which could jeopardize the

user's safety or the safety of others.

TSC uses sensors in the vehicle to recognize an exces-

sively swaying trailer and will take the appropriate

actions to attempt to stop the sway. TSC will become

active automatically once an excessively swaying trailer

is recognized. Note that TSC cannot stop all trailers from

swaying. Always use caution when towing a trailer and
