2011 JEEP LIBERTY torque

26. 4WD Indicator — Vehicles Equipped with
Selec-TracII
This light alerts the driver that the vehicle is in
the full-time four-wheel drive auto mode. In
this mode, the system operates with a normal
torque split of 42% front axle and 58% rear axle.
It can redirect up to 100% of torque to the front or rear
axle, if necessary.
27. Odometer Display/Trip Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven. The trip odometer shows indi-
vidual trip mileage. Refer to “Trip Odometer button” for
additional information.
NOTE: U.S. Federal regulations require that upon trans-
fer of vehicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has been
driven. If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he cannot do so, then the odometer must be set at zero, and
a sticker must be placed in the door jamb stating what the
mileage was before the repair or service. It is a good idea
for you to make a record of the odometer reading before
the repair/service, so that you can be sure that it is
properly reset, or that the door jamb sticker is accurate if
the odometer must be reset at zero.

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
Command-Trac IITransfer Case – If Equipped
Operating Information And Precautions
The Command-Trac II 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

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 “Starting
and Operating” for further information.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.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO 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. Tire rotation
schedule should be followed to balance tire wear.
328 STARTING AND OPERATING

Shift Positions
The transfer case switch is located on the center console
next to the shift lever.
2WD
Rear Wheel Drive High Range - This range is for normal
street and highway driving on dry hard-surfaced roads.4WD Auto
Four-Wheel Drive Auto High Range – This active on-
demand range makes available optimum traction for a
wide range of conditions, while maximizing driver con-
venience. This position is always in four-wheel drive
mode, with a normal 42% front axle, 58% rear axle torque
split. The system also anticipates and prevents slip by
redirecting torque as necessary, up to 100% to the front or
rear axle, if needed.
4WD Low
Four-Wheel Drive Low Range - This range is for 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).

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.

help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
WARNING!
The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the ve-
hicle, nor can it increase the traction afforded by
prevailing road conditions. ABS cannot prevent col-
lisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. 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.
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 system functions similar to
a limited slip differential and controls the wheel spin
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 or the “Full Off” mode. Refer to
“Electronic Stability Control (ESC)” in this section for
further information.

and reinstallation procedures, including flange orienta-
tion/alignment, use of thread-locking compound, proper
bolt torque specifications, etc.
CAUTION!
Towing with the rear wheels on the ground (while
the driveshaft is connected) will cause severe trans-
mission damage. Damage from improper towing is
not covered under the New Vehicle Limited War-
ranty.
Recreational Towing — Four-Wheel Drive Models
The transfer case must be shifted into NEUTRAL (N) and
the transmission must be placed in PARK for recreational
towing. The NEUTRAL (N) selection button is adjacent to
the transfer case selector switch. Shifts into and out of
transfer case NEUTRAL (N) can take place with the
selector switch in any mode position.
CAUTION!
•Front or rear wheel lifts should not be used.
Internal damage to the transmission or transfer
case will occur if a front or rear wheel lift is used
when recreational towing.
•Tow only in a forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
•The transmission must be placed in PARK for
recreational towing.
•Before recreational towing, perform the procedure
outlined under “Shifting into NEUTRAL (N)” to
be certain that the transfer case is fully in NEU-
TRAL (N). Otherwise, internal damage will result.
•Failure to follow these procedures can cause se-
vere transmission and/or transfer case damage.
•Do not use a bumper-mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.

and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause a collision. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and install
lug nuts with the cone-shaped end toward the wheel.
Lightly tighten the nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered. 8. Lower the vehicle by turning the jack screw to the left,
and remove the jack.
9. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. The correct
wheel nut tightness is 95 ft lb (130 N·m). If in doubt about
the correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service station.
10. Lower the jack to it’s fully closed position.
11. Secure the tire, jack, and tools in their proper loca-
tions.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop, could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
