JEEP LIBERTY 2010 KK / 2.G Service Manual

MP3022 Selec-Trac II®
Transfer Case
• The Selec-Trac II®active on-demand
transfer case provides 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 highway 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.
• When operating in 4WD LOW, the engine speed is approximately three
times that of the 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).
• Use the transfer case NEUTRAL position for recreational towing only.
2WD To 4WD AUTO
• Move transfer case lever to the desired
position.
• Shifts between 2WD and 4WD AUTO 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
moving the transfer case lever.
• If the vehicle is stopped, the key must be in the ON/RUN position.
• Shifts can not be completed if the key is in the ACC position.
4WD AUTO To 4WD LOW
• With the engine running, slow thevehicle speed to 2 to 3 mph (3 to
5 km/h) and shift the transmission into
NEUTRAL.
• While still rolling, move the transfer case lever to the 4WD LOW position.
• After the indicator light is ON (not flashing) shift the transmission into
gear.
• If the indicator light in the instrument cluster is flashing, the shift did not
occur and the current transfer case
position will be maintained.

INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Program (ESP) Indicator Light
• If this indicator light flashes during acceleration, apply as little throttle as possible. Whiledriving, ease up on the accelerator. Adapt your speed and driving to the prevailing road
conditions. To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESP system off.
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly, when cold andinflated to the inflation pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
• As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more
of your tires is significantly under-inflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire
to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s handling and stopping ability.
• Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
• Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists.
WHAT TO DO IN EMERGENCIES
44

• When the malfunction indicator is illuminated, the system may not be able to detect orsignal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to ensure
that the replacement or alternate tires and wheels allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over and stopthe vehicle. If the A/C system is on, turn it off. Also, shift the transmission into NEUTRAL
and idle the vehicle. If the temperature reading does not return to normal, turn the
engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant. You may want to call an authorized service center for
service if your vehicle overheats.

WHAT TO DO IN EMERGENCIES

BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or theparking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an Anti-Lock
Brake System problem.
• We recommend you drive to the nearest service center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have an accident.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., mayilluminate the MIL after engine start. The vehicle should be serviced if the light stays on
through several typical driving cycles. In most situations, the vehicle will drive normally
and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We recommend
you do not operate the vehicle. Have the vehicle serviced immediately.
- Electronic Stability Program (ESP) Indicator Light/Brake Assist
System (BAS) Warning Light
• If the ESP/BAS warning light comes on continuously with the engine running, a
malfunction has been detected.
• If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), we recommend you
drive to the nearest service center and have the vehicle serviced immediately.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging system lightremains on, it means that the vehicle is experiencing a problem with the charging

PARK position; the light should turn off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Airbag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have the vehicleserviced by an authorized service center immediately.
- SERV (Service) 4WD Indicator Light
• If the light stays on or comes on during driving, it means that the 4WD system is notfunctioning properly and that service is required. We recommend you drive to the nearest
service center and have the vehicle serviced immediately.
- Transmission Temperature Warning Light
• This light indicates that there is excessive transmission fluid temperature that mightoccur with severe usage such as trailer towing. If this light turns on, stop the vehicle and
run the engine at idle, with the transmission in NEUTRAL, until the light turns off. Once

WHAT TO DO IN EMERGENCIES

Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as gASCAP) appears, tighten the gas cap until a “clicking”sound is heard.
• Press the odometer reset button to turn the message off.
• If the message continues to appear for more than three days after tightening the gas cap, see your authorized service center.
Oil Change Indicator
Message
• If an “oil change” message (shown as CHAngE OIL) appears and a single chime sounds,it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating by takingthe appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the
radiator and aids in removing heat from the engine cooling system.
• If the temperature reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
