2006 JEEP COMMANDER overheating

Canadian Programming/Gate 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-
mingprocedures (regardless of where you live),replace
Programming HomeLinkstep 3with 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.
3. Continue to press and hold the HomeLink button
while youpress and release every two seconds(cycle)
your hand-held transmitter until the frequency signal has
successfully been accepted by HomeLink. The EVICdisplay will show “CHANNEL X TRAINED” (where X is
Channel 1, 2, or 3). Proceed withProgrammingstep
four 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.com or 1-800-355-
3515.
Erasing HomeLink Buttons
To erase programming from the three buttons (individual
buttons cannot be erased but can bereprogrammed-
note below), follow the step noted:

•When the temperature knob is in the cold (Blue)
position, cold air will be delivered from the outlets. As
the temperature knob is turned towards the hot (Red)
position, the air will get warmer.
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. (See page 351 for more
information.)
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
NOTE:Refer to the “Operating Tips” chart (for Manual
A/C Control) in this section for suggested control set-
tings in different weather conditions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

overheating or failure due to excessive shifting. When
operating in “TOW/HAUL” mode, the transmission will
shift to 3rd gear and 4th will be enabled under steady
cruise conditions.
The “TOW/HAUL” light will illuminate in the instru-
ment cluster to indicate when the switch has beenactivated. 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.
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 the current gear until the vehicle is brought to
a stop.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the P (Park) position.
3. Turn off the engine, be sure to turn the key to the
LOCK position.

cause damage to the transmission. The torque converter
will refill within five seconds of shifting from 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 D (Drive) and R (Reverse),
while applying slight pressure to the accelerator.
NOTE:The Electronic Stability Program (ESP) and
Traction Control (if equipped) should be turned OFF
before attempting to rock the vehicle. Refer to Section 3 of
this manual. (See page 131 for more information.)
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 transmissionselector 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.
CAUTION!
When “rocking” a stuck vehicle by moving between
“First” and R (Reverse), do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.

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.
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 331

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
vehicle.
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.
