SAFETY 101
maneuver to the driver. The coordinated action
of brakes and steering increases the safety and
car control feeling.
NOTE:
The DST is a driving aid system and does not
replace the driver’s actions while driving the
car.
Electronic Roll Mitigation (ERM)
The Electronic Roll Mitigation (ERM) system
anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When Electronic Roll
Mitigation (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, and it will only intervene during
these types of 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. Refer to Electronic Stability Control (ESC)
in Safety for a complete explanation of the avail-
able ESC modes.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system
enhances directional control and stability of the
vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the oversteer
or understeer condition. Engine power may also
be reduced to help the vehicle maintain the
desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will start
to flash as soon as the ESC system becomes
active. The “ESC Activation/Malfunction
Indicator Light” also flashes when the TCS is
active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during
acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing
road conditions.
WARNING!
Many factors, such as vehicle loading, road
conditions, 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 capabil-
ities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous man-
ner, which could jeopardize the user's safety
or the safety of others.
