The MIL is a part of an Onboard Diagnostic
System called OBD II that monitors engine and
automatic transmission control systems. This
warning light will illuminate when the ignition is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch 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 by an authorized dealer as soon as
possible if this occurs.
AdBlue® (UREA) Injection System Failure
Warning Light — If Equipped
This warning light will illuminate along with a
dedicated message on the display (if equipped)
if an unknown fluid not conforming with
acceptable characteristics is inserted, or if an
average consumption of AdBlue® (UREA) over 50% is
detected. Contact an authorized dealer as soon as
possible.
If the problem is not solved, a specific message will appear
on the instrument cluster display whenever a certain
threshold is reached until it will no longer be possible to
start the engine.
When about 125 miles (200 km) are remaining before the
AdBlue® (UREA) tank is empty, a continuous dedicated
message will appear on the instrument panel,
accompanied by a chime.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the 4WD system. If the light stays on or

nearest service center and have the vehicle serviced
immediately.
Service Adaptive Cruise Control Warning
Light — If Equipped
This light will turn on when a ACC is not
operating and needs service Úpage 152.
WARNING!
A malfunctioning catalytic converter, as previously
referenced, 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.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle 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.

Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the Forward Collision Warning System.
Contact an authorized dealer for service
Úpage 255.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control system is not functioning
properly and service is required. Contact an
authorized dealer.
Sway Bar Fault Warning Light
This light will illuminate when there is a fault in
the sway bar disconnect system Úpage 145.
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 consumption may not
be guaranteed. Should one or more tires be in the condition previously
mentioned, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under inflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoid
-
ing sharp braking and steering. If a tire puncture occurs,
repair immediately using the dedicated tire repair kit and
contact an authorized dealer as soon as possible.

CAUTION!
The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inopera -
ble. After using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an authorized
dealer to have your sensor function checked.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see an authorized dealer for service as soon as possible.
CAUTION!
 Prolonged driving with the MIL on could cause further
damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle
must be serviced before any emissions tests can be
performed.
 If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

23_JL_OM_EN_USC_t.book Page 124

GETTING TO KNOW YOUR INSTRUMENT PANEL125
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a connection
port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this information to
assist with the diagnosis and service of your vehicle and
emissions system
Úpage 184.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies the
Malfunction Indicator Light (MIL) is functioning
and is not on when the engine is running, and
that the OBD II system is ready for testing.
The OBD II system may not be ready if your vehicle was
recently serviced, recently had a depleted battery or a
battery replacement. If the OBD II system should be
determined not ready for the I/M test, your vehicle may fail
the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to start this
test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction Indicator Light
(MIL) symbol come on as part of a normal bulb check. 3. Approximately 15 seconds later, one of two things will
happen:
 The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that
your vehicle's OBD II system is not ready and you
should not proceed to the I/M station.
 The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off posi -
tion or start the engine. This means that your
vehicle's OBD II system is ready and you can
proceed to the I/M station.
If your OBD II system is not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the previously mentioned test
routine may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system is
ready or not, if the MIL is illuminated during normal vehicle
operation you should have your vehicle serviced before
going to the I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine running.
WARNING!
 ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.
