Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and the gauge approachesH, this
indicator will illuminate and a single chime will sound after reaching a set threshold. Further overheating will cause a con-
tinuous chime sound for 4 minutes, or until the engine is allowed to cool, whichever comes first.
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 normal, turn the engine off
immediately and call for service. Refer to “If Your Engine Overheats” in “What To Do In Emergencies” for further informa-
tion.

Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale Light What It Means
Engine Check/Malfunction Indicator Light (MIL)The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic System called OBD II that monitors en-
gine 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 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 Malfunction Indicator
Light (MIL) on could cause damage 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.
WARNING!
A malfunctioning catalytic converter, as ref-
erenced above, can reach higher tempera-
tures than in normal operating conditions.
This can cause a fire if you drive slowly or

Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change Re-
quired” message will display in the EVIC display
for approximately five seconds after a single
chime has sounded to indicate the next sched-
uled oil change interval. The engine oil change
indicator system is duty-cycle based, whichmeans the engine oil change interval may fluc-
tuate dependent upon your personal driving
style.
Unless reset, this message will continue to
display each time you place the ignition in the
ON/RUN position. To turn off the message
temporarily, push and release the Trip Odom-
eter button on the instrument cluster. To reset
the oil change indicator system (after perform-
ing the scheduled maintenance), refer to the
following procedure.

CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wireless
networks. These networks allow your vehicle to
send and receive information. This information
allows systems and features in your vehicle to
function properly.
Your vehicle may be equipped with certain
security features to reduce the risk of unauthor-
ized and unlawful access to vehicle systems
and wireless communications. Vehicle software
technology continues to evolve over time and
FCA US LLC, working with its suppliers, evalu-
ates and takes appropriate steps as needed.
Similar to a computer or other devices, your
vehicle may require software updates to im-prove the usability and performance of your
systems or to reduce the potential risk of unau-
thorized and unlawful access to your vehicle
systems.
The risk of unauthorized and unlawful access to
your vehicle systems may still exist, even if the
most recent version of vehicle software (such
as Uconnect software) is installed.WARNING!
•It is not possible to know or to predict all of
the possible outcomes if your vehicle’s
systems are breached. It may be possible
that vehicle systems, including safety re-
lated systems, could be impaired or a loss
of vehicle control could occur that may
result in an accident involving serious in-
jury or death.
