2009 JEEP LIBERTY wheel 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/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer button” for additional
information.
NOTE: U.S. Federal regulations require upon transfer of
vehicle ownership, the seller certify the mileage the
vehicle has been driven. Therefore, if the odometer
reading is changed because of repair or replacement, be sure to keep a record of the reading before and after the
service so that the correct mileage can be determined.
Vehicle Warning Messages
When the appropriate conditions exist, messages such as
“door” (door ajar), “gATE” (liftgate ajar), “gLASS”
(flip-up glass ajar), “gASCAP” (fuel cap fault), “LoW
tirE” (low tire pressure), or “CHANgE OIL” will display
in the odometer.
LoW tirE
When the appropriate condition exists, the odometer
display will toggle between LoW and tirE for three
cycles.
NOTE:
If the instrument cluster is equipped with the
optional Electronic Vehicle Information Center (EVIC),
then most warnings will display in the EVIC.

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.

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).
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, 4 LOW) are
located in the instrument cluster. The NEUTRAL indica-
tor light is located on the 4WD Control Switch. If there is
no indicator light on or flashing, the transfer case posi-
tion is two-wheel drive (2WD). If the indicator light is on,
the desired position (4WD AUTO, 4WD LOW, or NEU-
TRAL) 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.

Traction Downhill
Shift the transmission into a low gear and the transfer
case to 4WD LOW range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•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 brake rotors, wheels,
brake linings, and axle yokes inspected and cleaned as
soon as possible.

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 acci-
dents, including those resulting from excessive speed
in turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ABS-
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 andstability. 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 ESP are in the
“Partial Off” mode or the “Full Off” mode. Refer to
“Electronic Stability Program (ESP)” in this section for
more information.
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
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the

WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause an accident. 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. To avoid the risk of forcing the
vehicle off the jack, do not tighten the nuts fully until the
vehicle has been lowered.
8. Lower the vehicle by turning the jack screw to the left,
and remove the jack and wheel blocks. 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.
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.
11. Secure the tire, jack, and tools in their proper
locations.
