JEEP LIBERTY 2009 KK / 2.G Owners Manual

Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 4th speed (OVERDRIVE). The trans-
mission will automatically shift from 3rd gear to OVER-
DRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL button has not been activated
•the transmission has reached normal operating
temperature
NOTE:
•If the vehicle is started in extremely cold temperatures,
the transmission may not shift into OVERDRIVE and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
OVERDRIVE until the transmission cools down. After
the transmission cools down, the transmission will
resume normal operation.
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift to 3rd gear.
NOTE:TOW/HAUL mode locks out Overdrive.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.

Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will remain in second gear in any forward driving range.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.
3. Turn OFF the engine and be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only second gear range will operate in the DRIVE
position. Have the transmission checked at your autho-
rized dealer as soon as possible.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.

FOUR-WHEEL DRIVE OPERATION
MP1522 Command-TracTransfer Case — If
Equipped
Operating Information and Precautions
The Command-Trac transfer case provides four posi-
tions:
•Two–wheel drive (2WD) high range
•Four-wheel drive (4WD LOCK) high range
•Four-wheel drive (4WD LOW) low range
•Neutral (N)
This transfer case is intended to be driven in the two-
wheel drive position (2WD) for normal street and high-
way conditions such as dry hard-surfaced roads.
When additional traction is required, select the transfer
case 4WD LOCK position or 4WD LOW position. This position locks the front driveshaft and rear driveshaft
together and forces the front and rear wheels to rotate at
the same speed.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in this
section for specific procedures on shifting into and out of
NEUTRAL.
CAUTION!
•Do not attempt to make a shift while only the front
wheels or rear wheels are spinning. The MP1522
Command-Trac
transfer case is not equipped
with a synchronizer and therefore the speed of the
front driveshaft and rear driveshaft must be equal
for the shift to take place. Shifting while only the
front wheels or rear wheels are spinning can cause
damage to the transfer case.
(Continued)
302 STARTING AND OPERATING

CAUTION! (Continued)
•The 4WD LOCK position and 4WD LOW position
are intended for loose or slippery road surfaces
only. Driving in these positions on dry hard-
surfaced roads may cause increased tire wear and
damage to the driveline components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD LOCK position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
WARNING!
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging
the parking brake. The transfer case NEUTRAL
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.
•Always engage the parking brake when powering
down the vehicle if the “SERV 4WD Warning
Light” is illuminated. Not engaging the parking
brake may allow the vehicle to roll, which may
cause personal injury.(Continued)

WARNING! (Continued)
•Since four-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit. You or others could be injured.
Shift Positions
The electronic transfer case switch is located on the center
console next to the shift lever.2WD
Rear Wheel Drive High Range - This range is used for
normal street and highway driving on dry hard-surfaced
roads.
4WD Control Switch
304 STARTING AND OPERATING

4WD Lock
4-Wheel Drive High Range - This range locks the front
driveshaft and rear driveshaft together forcing the front
and rear wheels to rotate at the same speed. Additional
traction for loose or slippery road surfaces only.
4WD Low
4-Wheel Drive Low Range - This range provides low
speed four-wheel drive. Locks the front driveshaft and
rear driveshaft together forcing the front and rear wheels
to rotate at the same speed. Additional traction and
maximum pulling power for loose or slippery road
surfaces only. Do not exceed 25 mph (40 km/h).
N
Neutral - This range disengages both the front driveshaft
and rear driveshaft from the powertrain. To be used for
flat towing behind another vehicle. Refer to “Recreational
Towing” in this section for more information.Transfer Case Position Indicator Lights
The four-wheel drive indicator lights (4WD and 4 LOW)
are located in the instrument cluster. The NEUTRAL
indicator light is located on the 4WD Control Switch. If
there is no indicator light on or flashing, the transfer case
position is two-wheel drive (2WD). If the indicator light
is on, the desired position (4WD LOCK, 4WD LOW, or
NEUTRAL) has been obtained.
If one or more shift requirements are not met:
•An indicator light will flash.
•The transfer casewill notshift.
NOTE: The “SERV 4WD Warning Light” monitors the
electric shift four-wheel drive system. If this light re-
mains on after engine start up, or it illuminates during
driving, it means that the four-wheel drive system is not
functioning properly and that service is required.

Shifting Procedures
NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain on, and the newly selected position indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift, move
the 4WD Control Switch back to the original position,
make certain all shift requirements have been met, wait
five seconds, and try the shift again.
2WD to 4WD Lock
Move the 4WD Control Switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after mov-
ing the 4WD Control Switch. If the vehicle is stopped, the
ignition switch must be in the ON position with the engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
NOTE:
The four-wheel drive system will not allow
shifts between 2WD and 4WD LOCK if the rear wheels
are spinning (no traction). In this situation, the selected
position indicator light will flash and the original posi-
tion indicator light will remain ON. At this time, reduce
speed and stop spinning the wheels to complete the shift.
There may be a delay up to 10 seconds for the shift to
complete after the wheels have stopped spinning.
Delayed shifting out of 4WD LOCK may be experienced
due to uneven tire wear, low tire pressure, or excessive
loading.
4WD Lock to 4WD Low
When shifting into or out of 4WD LOW, some gear noise
may be heard. This noise is normal and is not detrimental
to the vehicle or its occupants
306 STARTING AND OPERATING

Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) using the “Preferred Procedure” or
completely stopped using the “Alternate Procedure.”
Preferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, move the 4WD Control Switch to
the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear.
Alternate Procedure
1. Bring the vehicle to a complete stop.2. With the ignition switch in the ON position, and the
engine OFF or RUNNING, shift the transmission into
NEUTRAL.
3. Move the 4WD Control Switch to the desired position.
4. After the desired position indicator light is on (not
flashing), shift the transmission into gear.
NOTE:
Steps 1 and 2 in the “Preferred Procedure” and
the “Alternate Procedure” are requirements for shifting
the transfer case. If these requirements are not met prior
to attempting the shift or while the shift attempt is in
process, then the indicator light will flash, and the
current transfer case position will be maintained. To retry
a shift, move the 4WD Control Switch back to the original
position, make certain all shift requirements have been
met, wait five seconds, and try the shift again.
The ignition switch must be in the ON position for a shift
to take place and for the position indicator lights to be

operable. If the ignition switch is not in the ON position,
then the shift will not take place and no position indicator
lights will be on or flashing.
MP3022 Selec-Trac IITransfer Case — If
Equipped
Operating Information and Precautions
The Selec-Trac II active on-demand transfer case pro-
vides four positions:
•Two-wheel drive (2WD) high range
•Four-wheel drive Auto (4WD AUTO) high range
•Neutral (N)
•Four-wheel drive (4WD) low range
This transfer case is intended to be driven in either the
two-wheel drive position (2WD) or the four-wheel drive
Auto position (4WD AUTO) for normal street and high-
way conditions such as dry hard-surfaced roads. For added capability when traversing steep grades,
rough terrain, or extremely poor traction surfaces, select
the transfer case 4WD LOW position. This position locks
the front driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the same
speed while multiplying engine torque.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in this
section for specific procedures on shifting into and out of
NEUTRAL.
CAUTION!
•The 4WD LOW position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline
components.
