CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
24. Odometer / Trip Odometer Display Area
The odometer display shows the total distance the vehicle
has been driven. The trip odometer shows individual trip
mileage. Refer to “Odometer / Trip Odometer / ECO
(Fuel Saver Indicator) Button” for additional information.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.

driving habits in order to increase fuel economy. LoW tirE
When the appropriate condition exists, the odometer
display will toggle between LoW and tirE for three
cycles.
“HOTOIL” Transmission Temperature Warning
Message
The “HOTOIL” cluster message will appear in the odom-
eter accompanied with a chime to indicate that there is
excessive transmission fluid temperature that might oc-
cur with severe usage such as trailer towing. It may also
occur when operating the vehicle in a high torque
converter slip condition, such as 4-wheel drive operation
(e.g., snow plowing, off-road operation). If this “HOT-
OIL” message turns on, stop the vehicle and run the
engine at idle or faster with the transmission in NEU-
TRAL until the message turns off.
278 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
Continuous driving with the Transmission Tempera-
ture “HOTOIL” Warning message illuminated will
eventually cause severe transmission damage or
transmission failure.
WARNING!
If the Transmission Temperature “HOTOIL” Warn-
ing message is illuminated and you continue operat-
ing the vehicle, in some circumstances you could
cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
noFUSE
If the vehicle diagnostic system determines that the
Ignition Off Draw (IOD) fuse is improperly installed, or
damaged, a “noFUSE” message will display in the odom-
eter display area. For further information on fuses and
fuse locations refer to “Fuses” in “Maintaining Your
Vehicle”.
CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty-cycle based, which
4
UNDERSTANDING YOUR INSTRUMENT PANEL 279

means the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure:1. Turn the ignition switch to the ON/RUN position
(do not start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure. 25. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON position before engine start. If the bulb does
not come on when turning the key from OFF to ON/
RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.

30. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash
depending on the nature of the problem. Cycle the
ignition key when the vehicle is safely and completely
stopped and the shift lever is placed in the PARK
position. The light should turn off. If the light remains on
with the engine running, your vehicle will usually be
drivable; however, see an authorized dealer for service as
soon as possible.
If the light continues to flash when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned to ON/RUN and remain on briefly as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer.

NOTE:The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.
The following displays can be reset or changed:
•Compass/Temperature
•AVG ECO (changes to present fuel economy)
•ET (will reset display)
•DTE (distance to empty)
These messages can be cycled through by pressing the
STEP button on the steering wheel. To reset the AVG ECO
or ET, press and hold the STEP button for approximately
three seconds.
Compass/Temperature Display
NOTE: If the vehicle is equipped with a Chrysler
Uconnect™ gps (Navigation Radio), the NAV system will
provide the compass direction, and the variance and
calibration menus will be unavailable. The compass will
perform accurately, based on GPS signals instead of the
Earth’s magnetic field.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly set,
the compass will automatically compensate for the differ-
ences and provide the most accurate compass heading.
NOTE:
•A good calibration requires a level surface and an
environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.

UNDERSTANDING YOUR INSTRUMENT PANEL 285

•Magnetic materials should be kept away from the top
of the center of the instrument panel. This is where the
compass sensor is located.
To Set The Variance
Start the engine and leave the transmission gear selector
lever in the PARK position. Press and hold the RESETbutton on the steering wheel (for approximately ten
seconds) until the current variance zone number is dis-
played. To change the zone, press and release the STEP
button to increase the variance one step. Repeat as
necessary until the desired variance is achieved.
NOTE:
The factory default zone is 8. During program-
ming, the zone value will wrap around from zone 15 to
zone 1.
Manual Compass Calibration
If the compass appears erratic, inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-
ing the compass, make sure the proper zone is selected.
1. Start the engine and leave the transmission in the
PARK position.
2. Press and hold the RESET button (for approximately
10 seconds) until the current variance zone number is
displayed.
