2009 JEEP LIBERTY fuel

•Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. DTE cannot be reset through the FUNCTION
SELECT button.
NOTE: Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to a text display of LOW FUEL.This display will
continue until the vehicle runs out of fuel. Adding a
significant amount of fuel to the vehicle will turn off the
LOW FUEL text and a new DTE value will display.•Elapsed Time
Shows the total elapsed time of travel since the last reset
when the ignition switch is in the ACC position. Elapsed
time will increment when the ignition switch is in the ON
or START position.
•Display Units of Measure in:
To make your selection, press and release the FUNC-
TION SELECT button until “ENGLISH” or “METRIC”
appears.
To Reset The Display
Reset will only occur while a resettable function is being
displayed. Press and release the FUNCTION SELECT
button once to clear the resettable function being dis-
played. To reset all resettable functions, press and release
the FUNCTION SELECT button a second time within
three seconds of resetting the currently displayed func-
tion (reset ALL will display during this three-second
window).

•MixAir is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to
the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
•Defrost Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in
Mix, Defrost, Floor, or a blend of these modes, even if the
Air Conditioning (A/C) button is not pressed. This
dehumidifies the air to help dry the windshield. To
improve fuel economy, use these modes only when
necessary.
•Recirculation Control Use this button to block the flow of outside air
from coming into the passenger compartment.
A light will illuminate when the system is in
recirculation mode. Only use the recirculation
mode as a temporary means to block out any outside
odors, smoke, or dust, and to cool the interior rapidly
upon initial start up in very hot or humid weather.
NOTE:
•Continuous use of the recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
•The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.

290 STARTING AND OPERATING

If Engine Fails to Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
292 STARTING AND OPERATING

With Tip Start
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded three-wire extension cord.
•The engine block heater cord is found under the hood
clipped to the heater line on the left side of the engine.

Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will remain in second gear in any forward driving range.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.
3. Turn OFF the engine and be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.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.

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.
