2009 JEEP COMMANDER Radio

CD/DVD MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch-
ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners,
or antistatic sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e. scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have theft protection encoding. Try a
known good disc before considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being ON in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.

Removing and Re-Installing the Engine Start/Stop
Button
The ENGINE START/STOP button may be removed
from the receptacle to allow the vehicle ignition to be
controlled conventionally by inserting the FOBIK. The
button may be removed using the valet key from the
FOBIK as a thin tool. Insert the metal part of the valet key
under the chrome bezel at the 6 o’clock position, and
gently pry the button loose.
To reinstall the button, position it with its lettering
oriented horizontal and readable. Gently insert the but-
ton into the receptacle by pressing on the center of the
button. If the button slips in easily, it has been installed
correctly. Press firmly on the center of the button to seat
the button into the receptacle.
The ENGINE START/STOP button should only be re-
moved or inserted with the ignition in the OFF position.

engine is obtained without pumping or depressing the
accelerator pedal.
STARTING AND OPERATING 293

The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition
of the vehicle brakes and tires or the traction
afforded.
(Continued)
WARNING! (Continued)
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
CAUTION!
The Anti-Lock Brake System (ABS) is subject to
possible detrimental effects of electronic interference
caused by improperly installed aftermarket radios or
telephones.
STARTING AND OPERATING 321

The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. In addition, a “CHECK TPM
SYSTEM” message will be displayed for 75 seconds when
a system fault is detected, and a chime will sound. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The Tire Pressure Moni-
toring Telltale Light will turn off when the fault condition
no longer exists. A system fault can occur by any of the
following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the Tire Pressure Monitoring Telltale Light to be
ON, a “TIRE LOW PRESSURE” message will be
displayed in the instrument cluster for 60 seconds, and
a chime to sound. Driving the vehicle for up to
20 minutes above 15 mph (24 km/h) will turn OFF the
Tire Pressure Monitoring Telltale Light as long as none
of the road tires are below the low pressure warning
threshold.
360 STARTING AND OPERATING

NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, theCHECK TPM SYSTEMmessage will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display aCHECK TPM SYSTEM
message for three seconds when a system fault is de-
tected possibly related to the trigger component. In this
364 STARTING AND OPERATING

2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the transmission in PARK, and turn
the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection, and personal
injury could result.5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.
6. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent.
•Personal injury or property damage due to battery
explosion.
