Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the ex-
haust system’s catalyst to trap and burn Par-
ticulate Matter (PM) pollutants, with no input
or interaction on your part.
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 exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. Refer to the following mes-
sages that may be displayed on your Instru-
ment Cluster Display:
• Exhaust Filter Nearing Full Safely Drive at
Highway Speeds to Clear — This message
will be displayed on the instrument cluster
display if the exhaust particulate filter
reaches 80% of its maximum storage ca-
pacity. Under conditions of exclusive short
duration and low speed driving cycles, your diesel engine and exhaust after-
treatment system may never reach the
conditions required to cleanse the filter to
remove the trapped PM. If this occurs, the
“Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy” message will
be displayed in the instrument cluster
display. If this message is displayed, you
will hear one chime to assist in alerting
you of this condition. By simply driving
your vehicle at highway speeds for up to
20 minutes, you can remedy the condition
in the particulate filter system and allow
your diesel engine and exhaust after-
treatment system to cleanse the filter to
remove the trapped PM and restore the
system to normal operating condition.
• Exhaust System Regeneration in Process
Continue Driving — This message indicates
that the Diesel Particulate Filter (DPF) is
self-cleaning. Maintain your current driv-
ing condition until regeneration is com-
pleted. •
Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed,
you will hear one chime to assist in alert-
ing you of this condition.
• Exhaust System Service Required - See
Dealer — This messages indicates regen-
eration has been disabled due to a system
malfunction. At this point the engine Pow-
ertrain Control Module (PCM) will register
a fault code, the instrument panel will
display a MIL light.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.
• Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
77

damage can occur. To correct this condi-
tion it will be necessary to have your ve-
hicle serviced by your local authorized
dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.

WARNING/INDICATOR
LIGHTS AND MESSAGES
IMPORTANT: The warning/indicator light
switches on in the instrument panel together
with a dedicated message and/or acoustic
signal when applicable. These indications
are indicative and precautionary and as such
must not be considered as exhaustive and/or
alternative to the information contained in
the Owner Manual, which you are advised to
read carefully in all cases. Always refer to the
information in this chapter in the event of a
failure indication.
All active telltales will display first, if appli-
cable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are
optional and may not appear.
Red Telltale Lights
– Seat Belt Reminder Warning Light
When the ignition switch is first turned to
ON/RUN, this light will turn on for four to
eight seconds as a bulb check. During the
bulb check, if the driver's seat belt is unbuck- led, a chime will sound. After the bulb check
or when driving, if the driver’s seat belt re-
mains unbuckled, the Seat Belt Reminder
Light will flash or remain on continuously and
a chime will sound.
– Air Bag Warning Light
This light will turn on for four to eight sec-
onds as a bulb check when the ignition
switch is first turned to ON/RUN. If the light
is either not on during startup, stays on, or
turns on while driving, have the system in-
spected at an authorized dealer as soon as
possible. This light will illuminate with a
single chime when a fault with the Air Bag
Warning Light has been detected, it will stay
on until the fault is cleared. If the light comes
on intermittently or remains on while driving,
have an authorized dealer service the vehicle
immediately.
– Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
GETTING TO KNOW YOUR INSTRUMENT PANEL
80

indicate that the parking brake is applied,
that the brake fluid level is low, or that there
is a problem with the anti-lock brake system
reservoir.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired. Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
two seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.

corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
– Engine Temperature Warning Light
This light warns of an overheated engine
condition. As engine coolant temperatures
rise and the gauge approachesH,this indica-
tor will illuminate and a single chime will
sound after reaching a set threshold.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
– Oil Temperature Warning Light
This telltale indicates engine oil temperature
is high. If the light turns on while driving,
stop the vehicle and shut off the engine as
soon as possible.
– Battery Charge Warning Light
This light illuminates when the battery is not
charging properly. If it stays on while the
engine is running, there may be a malfunc-
tion with the charging system. Contact your
authorized dealer as soon as possible. This
indicates a possible problem with the electri-
cal system or a related component.
If jump starting is required, refer to “Jump-
Starting” in “In Case Of Emergency.”
– Electronic Throttle Control (ETC)
Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a

Light
This light indicates that there is excessive
transmission fluid temperature that might
occur with severe usage such as trailer tow- ing. If this light turns on, stop the vehicle and
run the engine at idle, with the transmission
in NEUTRAL, until the light turns off. Once
the light turns off, you may continue to drive
normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
– Hood Open Warning Light
This indicator will illuminate when the hood
is left open and not fully closed.
Yellow Telltale Lights
– Engine Malfunction Warning Light
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control 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 illumi-
nate 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.
83

WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. 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.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the engine control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
– Electronic Stability Control (ESC)
Warning Light
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition switch
is turned to the ON/RUN position. It should
go out when the engine is running. If the “ESC Indicator 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.
• The “ESC Off Indicator Light” and the
“ESC Indicator Light” come on momen-
tarily 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.
This telltale indicates that an ESC event is
active.
– Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
– Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in se-
quence.
IMPORTANT: Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp brak-
ing and steering. Repair immediately using
the dedicated tire repair kit and contact your
authorized dealer as soon as possible.
