2007 JEEP LIBERTY overheating

If, after programming the HomeLink Wireless Control
System, the hand-held transmitter and/or other
HomeLink units in other vehicles fail to activate the
rolling code equipped device, you may need to clear (or
erase) the device’s receiver memory. Refer to your
garage door opener’s Owner’s Manual for the proce-
dure or contact HomeLink at 1-800-355-3515 or on the
Internet at www.homelink.com. After clearing the re-
ceiver, you must reprogram the original hand-held
transmitter(s) to the receiver using the procedure in the
garage door opener’s Owner’s Manual. Finally, repro-
gram the hand-held transmitter(s) to HomeLink using
the steps underProgramming HomeLink.
Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals totime-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 totime-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using theProgram-
ming HomeLinkprocedures (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
cyclingprocess 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 underProgramming
HomeLinkto complete.

time restores the Overdrive function. The lockout feature
is useful when towing a trailer or carrying a heavy load.
NOTE:If the vehicle is started in cold outside tempera-
tures, shifts into Overdrive may be delayed. Normal
Overdrive and shifting operation will resume when the
temperature of the transmission reaches the appropriate
temperature. Refer to the “Note” under “Torque Con-
verter Clutch” later in this section.
If the transmission temperature gets too hot, the trans-
mission may downshift out of Overdrive or engage
overdrive at higher vehicle speeds until the transmission
cools down. After cooldown, Overdrive will resume
normal operation.
2 (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.1 (First)
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 braking at low
speeds.
CAUTION!
•Never press on the accelerator pedal with the en-
gine running, vehicle in gear, and the brakes ap-
plied. Always apply the brakes when stopped on a
incline. Failure to follow these instructions can
cause overheating and damage to the transmission.
•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.
224 STARTING AND OPERATING

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, 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.
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.
WHAT TO DO IN EMERGENCIES 303

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
damage:
•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, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
