2006 JEEP LIBERTY warning light

the vehicle is safely and completely stopped and the gear
selector is placed in the P (Park) position. The light
should turn off. If the light remains on with the engine
running, your vehicle will usually be drivable, however,
see your dealer for service as soon as possible.
If the light continues to flash 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. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
NOTE: “Two-footed” driving is not recommended. In-
advertently driving with the brake pedal depressed for
more than a few seconds when the accelerator pedal is
held in place can cause the ETC system to assume that a
stuck accelerator pedal has occurred. This will result in a loss of power. Returning the brake pedal to its normal
position or moving the accelerator pedal will cancel this
condition. If the depressed brake pedal and the constant
accelerator pedal position are maintained for an extended
period of time, the ETC warning light will begin to flash
and continue until the ignition switch is cycled in the
same manner as above.
29. Glow Plug Indicator Light — Diesel Models Only
This light will illuminate when the ignition
switch is first turned to the ON position. Wait
until the light turns off before starting the
vehicle. Refer to “Starting Procedures — Nor-
mal Starting Diesel Engines” in Section 5 of this manual.

30. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light — If
EquippedThe ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the “ON” position. The light should
go out with the engine running. If the ESP/
BAS warning light comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at your authorized dealer
as soon as possible. Refer to “Electronic Brake Control
System” in Section 5 for more information. 31. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light —
If Equipped
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the ESP, or TCS — if
equipped. The indicator light will flash when the ESP or
TCS System is active and helping to improve vehicle
stability. If the indicator light is on solid, ESP or TCS may
not be able to function normally. Refer to “Electronic
Brake Control System” in Section 5 for more information.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle. 4WD Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.

operation may result in starter or battery damage. If
the engine does not start at once, repeat Steps 1
through 4.
•Cold engine speeds higher than necessary for driving
or higher than specified for idling may damage engine
components.
•Before turning off your Diesel engine, always allow
the engine to return to normal idle speed and then run
for several seconds. This assures proper lubrication of
the turbocharger. This is particularly necessary after
periods of high speed driving.
•“Two-footed” driving is not recommended. Inadvert-
ently driving with the brake pedal depressed for more
than a few seconds when the accelerator pedal is held
in place can cause the ETC system to assume that a
stuck accelerator pedal has occurred. This will result in
a loss of power. Returning the brake pedal to its
normal position or moving the accelerator pedal will cancel this condition. If the depressed brake pedal and
the constant accelerator pedal position are maintained
for an extended period of time, the ETC warning light
will begin to flash and continue until the ignition
switch is cycled in the following manner. Cycle the
ignition key when the vehicle is safely and completely
stopped and the gear selector is placed in the P (Park)
position.
Turbocharger “Cool Down”
NOTE:
Letting the engine idle after extended operation
allows the turbine housing to cool to normal operating
temperature.
The following chart should be used as a guide in deter-
mining the amount of engine idle time required to
sufficiently cool down the turbocharger before shut
down, depending upon the type of driving and the
amount of cargo.

Diesel Fuel-Water Separator
A diesel fuel-water separator separates the water nor-
mally found in diesel fuel. A manual hand prime pump is
located on the filter head for re-priming the fuel system.
The fuel-water separator is located on the driver side
cowl in the engine compartment. Refer to “2.8L Turbo
Diesel Engine Compartment” in Section 7 for location. NOTE:
If the “Water-In-Fuel Warning Light” (located in
the instrument cluster) comes on, this indicates that
water has collected in the fuel filter and should be
drained immediately. See your authorized dealer for
service.

CAUTION!
•Never press on the accelerator pedal with the
engine running, vehicle in gear, and the brakes
applied. Always apply the brakes when stopped
on a incline. Failure to follow these instructions
can cause overheating and damage to the trans-
mission.
•When “rocking” a stuck vehicle by moving be-
tween “First” and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
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.
NOTE:
•The torque converter clutch (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
232 STARTING AND OPERATING

TRAC-LOK™ REAR AXLE — IF EQUIPPED
The optional Trac-Lok™ rear axle provides a constant
driving force to both rear wheels and reduces wheel spin
caused by the loss of traction at one driving wheel. If
traction differs between the two rear wheels, the differ-
ential automatically proportions the usable torque by
providing more torque to the wheel that has traction.
Trac-Lok™ is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maxi-
mum traction. When starting with only one rear wheel on
an excessively slippery surface, slight application of the
parking brake may be necessary to gain maximum trac-
tion.WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to
lose control of your vehicle.
PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light.
NOTE: The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
STARTING AND OPERATING 243

To release the parking brake, pull up slightly, press the
center button, then lower the lever completely.
Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position. Make certain the
transfer case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).WARNING!
•Leaving children unattended in a vehicle is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up
may cause serious injury or death.
