2012 DODGE JOURNEY Owners Manual

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 con-
trol. You could have a collision. Have the vehicle
checked immediately.

Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up to help
avoid skidding on slippery surfaces during braking. Refer
to “Anti-Lock Brake System (ABS)” under “Electronic
Brake Control System” in this section for more information.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. ABS
cannot prevent collisions, including those resulting
from excessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. The capabilities of an
ABS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Traction Control System (TCS),
Electronic Roll Mitigation (ERM), Electronic Stability
Control (ESC), and Trailer Sway Control (TSC). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
400 STARTING AND OPERATING

related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS is
working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•The clicking sound of solenoid valves,
•Brake pedal pulsations, and
•A slight drop or fall away of the brake pedal at the end
of the stop.These are all normal characteristics of ABS.
WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.

WARNING! (Continued)
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The Anti-Lock Brake Light monitors the ABS.
The light will turn on when the ignition switch
is turned to the ON position and may stay on
for as long as four seconds.
If the ABS Light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the Brake System Warning Light is not on.
If the ABS Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock brakes. If the ABS Light does not come on
when the ignition switch is turned to the ON position,
have the light repaired as soon as possible.
402 STARTING AND OPERATING

If both the Brake System Warning Light and the ABS
Light remain on, the ABS and Electronic Brake Force
Distribution (EBD) systems are not functioning. Immedi-
ate repair to the ABS system is required.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
ABS. Applying the brakes very quickly results in the best
BAS assistance. To receive the benefit of the system, you
must apply continuous braking pressure during the
stopping sequence, (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
BAS cannot prevent the natural laws of physics from
acting on the vehicle, nor can it increase the traction
afforded by prevailing road conditions. BAS cannot
prevent accidents, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a BAS-
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.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS functions similar to a
limited slip differential and controls the wheel spin
5
STARTING AND OPERATING 403

across a driven axle. If 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.
This feature remains active even if TCS and ESC are in
the “Partial Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for more information.
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 will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce thechance 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 road-
way, or striking objects or other vehicles.
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 rollovers, 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.
404 STARTING AND OPERATING

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering and under-steering the vehicle by
applying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of over-steer or under-steer.
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started the system will be in this mode. This
mode should be used for most driving situations. ESC
should only be turned to “Partial Off” for specific reasons
as noted. Refer to “Partial Off” for additional informa-
tion.
Partial Off
The “ESC OFF” button is located in the switch bank
above the climate control. To enter the “Partial Off”
mode, momentarily press the “ESC OFF” button and the
“ESC Activation/Malfunction Indicator Light” will illu-
minate. To turn the ESC on again, momentarily press the
5
STARTING AND OPERATING 405

“ESC OFF” button and the “ESC Activation/Malfunction
Indicator Light” will turn off. This will restore the normal
“ESC On” mode of operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the “Partial Off” mode by momentarily pressing the “ESC
OFF” button. Once the situation requiring “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC OFF” button. This may be done while
the vehicle is in motion.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
