After placing the ignition in the ON/RUN position,
the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on
after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than
10 seconds), it indicates that there is a fault in the
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer. All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics

EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery
Sensor (IBS) to perform additional monitoring of
the electrical system and status of the vehicle
battery. In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions will
take place to extend the driving time and distance
of the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a risk
of battery depletion to the point where the vehicle
may stall due to lack of electrical supply, or will not
restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On” or “Battery Saver Mode” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
NOTE:
The charging system is independent from load
reduction. The charging system performs a diag
-
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system

The electrical loads that may be switched off (if
equipped), and vehicle functions which can be
affected by load reduction:
Heated Seat/Vented Seats/Heated Wheel
Heated/Cooled Cup Holders — If Equipped
Rear Defroster And Heated Mirrors
HVAC System
115 Volts AC Power Inverter System
Audio and Telematics System
Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capability
of the charging system. The charging system is
still functioning properly.

Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights,
overloaded power outlets +12 Volts, 115 Volts AC,
USB ports) during certain driving conditions (city
driving, towing, frequent stopping).

Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volts portable appliances
like vacuum cleaners, game consoles and
similar devices.
What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte -
rior)
Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume) After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate 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.
Always refer to the information in this chapter in
the event of a failure indication. All active telltales
will display first if applicable. The system check
menu may appear different based upon

RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and will
turn on for four to eight seconds as a bulb
check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light will
illuminate with a single chime when a fault with the
air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during
startup, stays on, or turns on while driving, have
the system inspected at an authorized dealer as
soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may 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 hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition 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 indicated by the Brake Warning
Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a
specified 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.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic 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 required.
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 illuminate, have the light inspected by an
authorized 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 appli
-
cation.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays
on while the engine is running, there may
be a malfunction with the charging
system. Contact an authorized dealer as soon as
possible.
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.

Warning Light
This warning light will turn on when
there's a fault with the EPS system
Ú page 94.
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
indicate a problem with the ETC system.
If a problem is detected while the vehicle
is running, the light will either stay on or
flash depending on the nature of the problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed
in the PARK position. The light should turn off. If
the light remains on with the vehicle running, your
vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
NOTE:This light may turn on if the accelerator and brake
pedals are pressed at the same time.
If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on
when the ignition is placed in the ON/RUN or ACC/
ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting,
have the system checked by an authorized dealer.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too high,
this indicator will illuminate and a single
chime will sound. If the temperature reaches the
upper limit, a continuous chime will sound for four
minutes or until the engine is able to cool:
whichever comes first. If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (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
Ú
page 228.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to
indicate the engine oil temperature is
high. If the light turns on while driving,
stop the vehicle and shut off the engine
