GETTING TO KNOW YOUR INSTRUMENT PANEL 137
Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low
Ú page 376.
Engine Check/Malfunction Indicator
Warning Light (MIL)
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 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 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 Ú page 304.
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.
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.
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.
