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
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:
Turn the ignition switch to the ON/RUN position (do not
start the engine). Fully depress the accelerator pedal slowly three times
within 10 seconds.
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.
CAUTION!Prolonged driving with the MIL on could cause damage
to the engine control system. It also could affect fuel
economy and drivability. If the MIL is flashing, severe
catalytic converter damage and power loss will soon
occur. Immediate service is required. WARNING!A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
26. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the312 UNDERSTANDING YOUR INSTRUMENT PANEL

engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
The “ESC Off Indicator Light” and the “ESC Activation/
Malfunction Indicator Light” come on momentarily each
time the ignition switch is turned to ON/RUN.
Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously. The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver that
caused the ESC activation.
WARNING!The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent acci-
dents, including those resulting from excessive speed
in turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of an ESC-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

27. Sway Bar Indicator Light — If Equipped
This indicator will illuminate when the front
sway bar is disconnected.
28. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
29. Electronic Throttle Control (ETC) Light
This 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.314 UNDERSTANDING YOUR INSTRUMENT PANEL

Under certain conditions, the mobile 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 mobile 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 mobile phone operation when
not using Uconnect™ (if equipped).

• Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
• The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
• The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or Bi-Level.
• The A/C can be deselected manually without disturb-
ing the mode control selection.
