engine DODGE JOURNEY 2012 1.G Repair Manual

During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid
is warm (refer to the “Note” under “Torque Converter
Clutch” in this section). During extremely cold tempera-
tures (-16°F [-27°C] or below), operation may briefly be
limited to third gear only. Normal operation will resume
once the transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in third gear regardless of which forward gear is selected.PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Limp Home Mode allows the vehicle to be driven to
an authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
388 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, it is
recommended that you visit an authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (sixth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
•the shift lever is in the DRIVE position,
•the transmission fluid has reached an adequate tem-
perature,
•the engine coolant has reached an adequate tempera-
ture, and
•vehicle speed is sufficiently high.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because the engine speed is higher when the torque
converter clutch is not engaged, it may seem as if the
transmission is not shifting into Overdrive when cold.
This is normal. Using the AutoStick feature, when the
transmission is sufficiently warm, will demonstrate that
the transmission is able to shift into and out of Overdrive.

AUTOSTICK— IF EQUIPPED
AutoStickis a driver-interactive feature providing
manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
When the shift lever is in the AutoStick position (below
the DRIVE position), it can be moved from side to side.
This allows the driver to manually select the transmission
gear being used. Moving the shift lever to the left (-)
triggers a downshift and to the right (+) an upshift. The
gear position will display in the instrument cluster on the
transmission range indicator. NOTE:
In AutoStick mode, the transmission will only
shift up or down when the driver moves the shift lever to
the right (+) or left (-), except as noted below. AutoStick
is deactivated when the shift lever is moved out of the
AutoStick (+/-) position.
General Information
•
You can launch the vehicle from a stop in any gear
except top gear. The system will ignore attempts to
upshift into top gear at too low of a vehicle speed.
•If a ratio other than first is selected, and the vehicle is
brought to a stop, the transmission control logic will
automatically select the first gear ratio.
•Starting out in second gear is helpful in snow or icy
conditions. To select second gear after the vehicle is
brought to a stop, tap the shift lever to the right (+)
once.
390 STARTING AND OPERATING

•Avoid using speed control when AutoStickis en-
gaged.
•Transmission shifting will be more noticeable when
AutoStick is engaged.
•If a downshift would cause the engine to over-speed,
that shift will not occur until it is safe for the engine.
•The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
•Mostly the transmission will stay in the manually
selected ratio, however:
If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
If the system detects a problem, it will disable the
AutoStick mode and the transmission will return to
the automatic mode until the problem is corrected.
ALL WHEEL DRIVE (AWD) — IF EQUIPPED
This feature provides on-demand All-Wheel Drive
(AWD). The system is automatic with no driver inputs or
additional driving skills required. Under normal driving
conditions, the front wheels provide most of the traction.
If the front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a pre-emptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
394 STARTING AND OPERATING

checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for the correct fluid
type.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the
transmission in PARK.
The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
park brake, firmly push the park brake pedal fully. To
release the parking brake, press the park brake pedal a
second time and let your foot up as you feel the brake
disengage.
396 STARTING AND OPERATING

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.
5
STARTING AND OPERATING 399

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
