BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application and
greater pedal force required to slow or stop the vehicle. In
addition, if the malfunction is caused by a leak in the
hydraulic system, the “Brake Warning Light” will turn on
as the brake fluid level drops in the master cylinder.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WARNING!
• Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. You would not
have your full braking capacity in an emergency.
• Driving a vehicle with the “Brake Warning Light”
on is dangerous. A significant decrease in braking
performance or vehicle stability during braking
may occur. It will take you longer to stop the
vehicle or will make your vehicle harder to control.
You could have a collision. Have the vehicle
checked immediately.

SAFETY 197

•If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in the “Multimedia” section for
further information.
For vehicles not equipped with the EVIC, perform the
following steps:
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within
twenty seconds. The “ESC Off Indicator Light” should
turn on and turn off two times. 7. Rotate the steering wheel back to center and then an
additional slightly more than one-half turn to the
right.
8. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial and controls the wheel spin across a driven axle. If
6
SAFETY 203

one wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied
to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects 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. En-
gine 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 matchthe intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” lo-
cated 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.
204 SAFETY

WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Par-
tial Off” mode, the engine power reduction feature of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
(Continued)
WARNING!(Continued)
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user ’s safety or the safety of
others.
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
6
SAFETY 205

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.
WARNING!
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
(Continued)
WARNING! (Continued)
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.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and EPS
modules that provides torque at the steering wheel for
certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain
vehicle stability. The only notification the driver receives
that the feature is active is the torque applied to the
steering wheel.
206 SAFETY

WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint Controller
System serviced as well.
NOTE:
• Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•
Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power or for 15 minutes from the
intervention of the Enhanced Accident Response Sys-
tem.
• Unlock the power door locks.
• Turn off the Fuel Pump Heater.
• Turn off the HVAC Blower Motor.
• Close the HVAC Circulation Door.

message regarding fuel cutoff is displayed. Turn the
ignition switch from ignition AVV/START or MAR/
ACC/ON/RUN to ignition STOP/OFF/LOCK. Care-
fully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine com-
partment and fuel tank before resetting the system and
starting the engine.
Depending on the nature of the event the left and right
turn signal lights, located in the instrument panel, may
both be blinking and will continue to blink. In order to
move your vehicle to the side of the road, you must

The air bags must be ready to inflate for your protection in a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If the
ignition switch is in the STOP/OFF/LOCK position the
air bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first turned to
