2009 JEEP LIBERTY overheating

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to “time-out” (or quit) after several seconds of
transmission – which may not be long enough for
HomeLinkto pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to “time-out” in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace “Programming
HomeLink” Step 3 with the following:
3. Continue to press and hold the HomeLink button
while you press and release - every two seconds
(“cycle”) your hand-held transmitter until HomeLink has successfully accepted the frequency signal. The
indicator light will flash slowly and then rapidly when
fully trained.
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under “Programming
HomeLink” earlier in this section.
Using HomeLink
To operate, simply press and release the programmed
HomeLink
button. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
Security system, entry door lock, home/office lighting,
etc. The hand-held transmitter of the device may also be
used at any time.

20. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Indicator Light – If EquippedThe malfunction indicator for the Electronic
Stability Program (ESP) is combined with the
Brake Assist System (BAS). The yellow “ESP/
BAS Warning Light” in the instrument cluster
comes on when the ignition switch is turned to the ON
position. It 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, or both. If this light
remains on after the several ignition cycles, and the
vehicle has been driven several miles/kilometers at
speeds greater than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE: The ESP Control System will make buzzing or
clicking sounds when it is active. This is normal; the sound will stop when the ESP becomes inactive following
a maneuver that caused the ESP activation.
21. SERV (Service) 4WD Indicator Light — If Equipped
The “SERV 4WD Indicator Light” will turn on
when the ignition key is turned to the ON
position and it will stay on for two seconds. If
the light stays on or turns on during driving, it
means that the 4WD system is not functioning properly
and that service is required.
22. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H, this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H, the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pressing the RECIRCULATION button.
However, under certain conditions, while in Auto-
matic Mode, the system is blowing air out the defrost
vents. When these conditions are present, and the
RECIRCULATION button is pressed, the indicator will
flash and then turn off. This tells you that you are
unable to go into recirculation mode at this time. If you
would like the system to go into Recirculation mode,
you must first move the Mode Knob to Panel, Panel/
Floor and then press the RECIRCULATION button.
This feature reduces the possibility of window
fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift to 3rd gear.
NOTE:TOW/HAUL mode locks out Overdrive.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.

300 STARTING AND OPERATING

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located in the
switch bank below the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition switch is in the LOCK position.
NOTE: With extended use, the Hazard Warning flasher
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating your engine by taking the
appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately and call for service.
394 WHAT TO DO IN EMERGENCIES

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, safely
bring the vehicle to a complete stop, turn off the engine,
and allow it to cool. Service, including a tune up to
manufacturer’s specifications, should be obtained imme-
diately.
