SAFETY 227
NOTE:
The “ESC Activation/Malfunction Indicator Light” and
the “ES
C OFF Indicator Light” come on momentarily each
time the ignition is turned ON.
Each time the ignition is turned ON, the ESC system will
be on e
ven if it was turned off previously.
The ESC system will make buzzing or clicking sounds
when it
is active. This is normal; the sounds will stop when
ESC becomes inactive following the maneuver that caused
the ESC activation.
The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Stability
C
ontrol
(ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by moni-
toring the driver’s steering wheel input and the speed of the
v
ehicle.
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 maneu
-
vers; it cannot prevent wheel lift due to other factors, such as
road con
ditions, 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.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying tra
iler and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati
-
cally once an excessively swaying trailer is recognized.
WARNING!
Many factors, such as vehicle loading, road conditions
and drivi
ng 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 reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.
