2010 JEEP LIBERTY overheating

7. Return to the vehicle and press the programmed
HomeLinkbutton twice (holding the button for two
seconds each time). If the device is plugged in and
activates, programming is complete.
If the device does not activate, press the button a third
time (for two seconds) to complete the training.
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
www.HomeLink.com for information or assistance.
To program the remaining two HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
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
HomeLink to 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 (“cycle”), your handheld
transmitter every two seconds until HomeLink has
successfully accepted the frequency signal. The indica-
tor light will flash slowly and then rapidly when fully
trained.
If you unplugged the device for training, plug it back in
at this time.

20. Electronic Stability Control (ESC) OFF Indicator
Light — If EquippedThis light indicates the Electronic Stability Con-
trol (ESC) is off.
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.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.
23. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
Recirculation to be selected while in floor, defrost, or
defrost/floor mode. Attempting to use the recircula-
tion while in these modes will cause the LED in the
control button to blink and then turn off.
•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 Automatic 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 thesystem 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 solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in Section 7 of this
manual for proper coolant selection.

2 (Second)
This range is used for moderate grades and to assist
braking on dry pavement or in mud and snow. Begins at
a stop in low gear with automatic upshift into second
gear. Will not shift into third gear.
1 (First)
This range is used for hard pulling at low speeds in mud,
sand, snow, or on steep grades. Begins and stays in low
gear with no upshift. Provides engine compression brak-
ing at low speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth gear (OVERDRIVE). The
transmission will automatically shift from third gear into
OVERDRIVE if the following conditions are present:
•the shift lever is in DRIVE
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL button has not been activated
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
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 into third gear.5
STARTING AND OPERATING 307

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.
404 WHAT TO DO IN EMERGENCIES

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
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.
