Jeep Liberty (2012 year). Instruction — part 29

FREEING A STUCK VEHICLE

If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the
wheels, is most effective.

CAUTION!

Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.

NOTE:

If your vehicle is equipped with Traction Con-

trol or Electronic Stability Control (ESC), turn the system
OFF before attempting to “rock” the vehicle.

CAUTION!

• When “rocking” a stuck vehicle by moving be-

tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.

• Revving the engine or spinning the wheels too fast

may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).

448

WHAT TO DO IN EMERGENCIES

WARNING!

Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.

SHIFT LEVER OVERRIDE

If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:

1. Firmly apply the parking brake.

2. Using a screwdriver or similar tool, carefully remove
the shift lever override access cover, located on the
PRNDL bezel.

3. Turn the ignition to the ON/RUN position without
starting the engine (engine Off).

4. Press and maintain firm pressure on the brake pedal.

5. Using a screwdriver, reach into the opening and press
and hold the shift override lever down.

6. Move the shift lever to the NEUTRAL position.

7. The vehicle may then be started in NEUTRAL.

8. Reinstall the shift lever override access cover.

TOWING A DISABLED VEHICLE

This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to

main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws applying to
vehicles under tow must be observed.

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.

WHAT TO DO IN EMERGENCIES

451

If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.

CAUTION!

• Do not attempt to use sling type equipment when

towing. When securing the vehicle to a flat bed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.

• If the vehicle being towed requires steering, the

ignition must be in the ON/RUN or ACC position,
not in the LOCK/OFF position.

Towing Without The Ignition Key Fob

Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.

Two-Wheel Drive Models

The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.

If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) with the transmission in NEU-
TRAL

. Speed must not exceed 30 mph (48 km/h) and the

distance must not exceed 15 miles (24 km).

452

WHAT TO DO IN EMERGENCIES

CAUTION!

Towing faster than 30 mph (48 km/h) or farther than
15 miles (24 km) with rear wheels on the ground can
cause severe damage to the transmission. Such dam-
age is not covered by the New Vehicle Limited
Warranty.

If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
15 miles (24 km), tow with the rear wheels OFF the
ground (on a flatbed, or with the rear wheels raised using
a wheel lift or towing dolly), or remove the driveshaft.

WARNING!

If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.

The parking brake must be firmly engaged and the
wheels chocked

during driveshaft removal and installa-

tion. The parking brake must remain engaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and

reinstallation

procedures,

including

flange

orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.

Four-Wheel Drive Models

The manufacturer recommends towing with all wheels
OFF

the ground. Acceptable methods are to tow the

vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.

If flatbed equipment is not available, and the transfer
case is operable, the vehicle may be towed (in the
forward direction, with ALL wheels on the ground), IF
the transfer case is in NEUTRAL and the transmission is
in PARK. Refer to “Recreational Towing” in “Starting
And Operating” for detailed instructions.

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 towing.

• Failure to follow these towing methods can cause

severe damage to the transmission and/or transfer
case. Such damage is not covered by the New
Vehicle Limited Warranty.

ONBOARD DIAGNOSTIC SYSTEM — OBD II

Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.

If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.

CAUTION!

• Prolonged driving with the MIL on could cause

further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.

• If the MIL is flashing while the engine is running,

severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

Loose Fuel Filler Cap Message

If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer or a
“CHECK gASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to

458

MAINTAINING YOUR VEHICLE

“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until a

⬙clicking⬙ sound is heard.

This is an indication that the gas cap is properly tight-
ened.

Press the odometer reset button to turn the message off.
If the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL light off.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS

In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.

For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not

on when the engine is running, and that the OBD II
system is ready for testing.

Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.

Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:

1. Turn the ignition switch to the ON position, but do not
crank or start the engine.

7

MAINTAINING YOUR VEHICLE

459

2. If you crank or start the engine, you will have to start
this test over.

3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.

4. Approximately 15 seconds later, one of two things will
happen:

a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not ready and you should
not

proceed to the I/M station.

b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.

If your OBD II system is not ready, you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.

Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

REPLACEMENT PARTS

Use of genuine MOPAR

威 parts for normal/scheduled

maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR

威 parts for maintenance

and repairs will not be covered by the manufacturer’s
warranty.

DEALER SERVICE

Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.

NOTE:

Intentional tampering with emissions control

systems may void your warranty and could result in civil
penalties being assessed against you.

WARNING!

You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.

MAINTENANCE PROCEDURES

The pages that follow contain the required maintenance
services determined by the engineers who designed your
vehicle.

Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.

MAINTAINING YOUR VEHICLE

461

CAUTION!

• Failure to properly maintain your vehicle or per-

form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized Chrysler Group LLC
dealership or qualified repair center.

• Your vehicle has been built with improved fluids

that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.

Engine Oil

Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed up engine is shut off.

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding 1 quart (0.9 L) of oil when the reading is
at the bottom of the SAFE zone will result in a reading at
the top of the safe zone on these engines.

462

MAINTAINING YOUR VEHICLE

CAUTION!

Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.

Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.

NOTE:

Under no circumstances should oil change

intervals exceed 8,000 miles (13 000 km) or six months,
whichever occurs first.

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer recom-
mends engine oils that are API Certified and meet the
requirements of Chrysler Material Standard MS-6395.

American Petroleum Institute (API) Engine Oil
Identification Symbol

This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
