2010 JEEP LIBERTY transmission

the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever in the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.
REVERSE
This range is for moving the vehicle rearward. Use this
range only after the vehicle has come to a complete stop.
NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with shift lever in NEUTRAL can result in
severe transmission damage. Refer to “Recreational Tow-
ing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
This range is used for most city and highway driving.
306 STARTING AND OPERATING

2 (Second)
This range is used for moderate grades and to assist
braking on dry pavement or in mud and snow. Begins at
a stop in low gear with automatic upshift into second
gear. Will not shift into third gear.
1 (First)
This range is used for hard pulling at low speeds in mud,
sand, snow, or on steep grades. Begins and stays in low
gear with no upshift. Provides engine compression brak-
ing at low speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth gear (OVERDRIVE). The
transmission will automatically shift from third gear into
OVERDRIVE if the following conditions are present:
•the shift lever is in DRIVE
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL button has not been activated
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 into third gear.5
STARTING AND OPERATING 307

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 nor-
mal 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 into the PARK position.
3. Turn the engine off and turn the key to the LOCK
position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever into the desired gear range.

308 STARTING AND OPERATING

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 positions:
•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

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.

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 transfer case 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.
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 transfer case switch to the
desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear.
314 STARTING AND OPERATING

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 transfer case 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 transfer case 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.
