2006 JEEP LIBERTY overheating

garage door opener’s Owner’s Manual. Finally, repro-
gram the hand-held transmitter(s) to HomeLink using
the steps under Programming HomeLink .
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-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using the Program-
ming HomeLink procedures (regardless of where you
live), replace step two with the following:
NOTE: If programming a garage door opener or gate
operator, it is advised to unplug the device during the
 cycling process to prevent possible overheating. Press and hold the HomeLink button while you press
and release - every two seconds (
cycle) your hand-held
transmitter button until the radio signal has success-
fully been accepted by HomeLink. (The message
TRAINED will appear on the HomeLink display.)
Proceed with the remaining steps under Programming
HomeLink to complete.
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.). For convenience, the hand-held transmitter of the
device may also be used at any time. In the event that
there are still programming difficulties or questions,
contact HomeLink at: www.homelink.comor1-800-355-

150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Summer Operation
Air conditioned equipped vehicle’s cooling systems must
be protected with a high quality engine coolant during
summer to provide proper corrosion protection and to
raise the boiling point of the coolant for protection
against overheating. A 50% concentration is recom-
mended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

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

(48 km/h). To understand the difference in operation,
drive the vehicle so that TCC engagement conditions
are correct, and then press and release the “O/D OFF”
button once to disengage the TCC. Wait a few seconds,
and then press and release the “O/D OFF” button
again to engage the TCC. You will notice that the
engine runs at a higher RPM when driving at vehicle
speeds above approximately 30 mph (48 km/h) with
the TCC not engaged. This is a normal condition.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Rocking the Vehicle
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between “First” and R (Reverse),
while applying slight pressure to the accelerator.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
the vehicle, may lead to transmission overheating and
failure. Allow the engine to idle with the transmission
selector in N (Neutral) for at least one minute after every
five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during
prolonged efforts to free a stuck vehicle.
STARTING AND OPERATING 233

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in N
(Neutral), but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
Control to maximum heat, the Mode Control to floor, and
the Fan Control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system. If the pointer rises to the “H” (hot mark) on a vehicle
equipped with a
gasoline engine, pull over and stop the
vehicle. Do not turn the engine off. Idle the vehicle with
the air conditioning turned off, until the pointer drops
back into the normal range.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.
WHAT TO DO IN EMERGENCIES 301

If the coolant temperature of a vehicle equipped with a
diesel engine approaches the “H” (hot mark) a warning
chime will sound to alert the driver. The air conditioning
system will turn off automatically and power loss will
occur until the engine temperature returns to the normal
range.
If the overheating condition persists a continuous chime
will sound to alert the driver. Reduce the vehicle speed
and or stop the vehicle while allowing the engine to idle
and cool the engine.JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
302 WHAT TO DO IN EMERGENCIES

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 ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing.
•Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
•Do not allow vehicle to run out of fuel.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
