— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
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.
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 illumi-
nate the light after engine start. The vehicleshould 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.
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-

CAUTION!
age 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.
— 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 conform-
ing with acceptable characteristics is in-
serted, or if an average consumption of Ad-
Blue (UREA) over 50% is detected. Contact
an authorized dealer as soon as possible.
If the problem is not solved, a specific mes-
sage 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 mi (200 km) are remaining
before the AdBlue (UREA) tank is empty, a
continuous dedicated message will appear on
the instrument panel, accompanied by a
buzzer sound (If Equipped).
SERV4WD— 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 comes on during driving, it means that
the 4WD system is not functioning properly
and that service is required. We recommend
you drive to the nearest service center and
have the vehicle serviced immediately.
— 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 autho-
rized dealer for service.
— Speed Control Fault Warning Light
This warning light will illuminate to indicate
the Speed Control System is not functioning
properly and service is required. Contact an

— Sway Bar Fault Warning Light
This light will illuminate when there is a fault
in the sway bar disconnect system.
— 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.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-GETTING TO KNOW YOUR INSTRUMENT PANEL

mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact an autho-
rized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (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 Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
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 under-inflation 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 se-
quence will continue upon subsequent ve-
hicle 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 replace-ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion 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!
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 replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
your 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 operatingproperly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag-
nostic 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 dam-
age and power loss will soon occur. Im-
mediate service is required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (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.
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 ve-
hicle control could occur that may
result in an accident involving seri-
ous injury or death.
