ODE MESSAGE — ELECTRICAL LOAD
R
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
fa

ilure, 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
r u

nning. 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
“ B

attery Saver On” or “Battery Saver Mode” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a
l ow

state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.

GETTING TO KNOW YOUR INSTRUMENT PANEL 71
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
Ú page 73.
The electrical loads that may be switched off (if
e q

uipped), and vehicle functions which can be
affected by load reduction:
Heated Seat/Vented Seats/Heated Wheel —
If Equipped
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
m or

e 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
c
on

ditions (city driving, towing, frequent stop -
ping).
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 Volt portable appliances
like vacuum cleaners, game consoles and
similar devices.
What to do when an electrical load reduction
a c

tion 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.
PROGRAMMABLE FEATURES

GETTING TO KNOW YOUR INSTRUMENT PANEL 73
Seat Belt Reminder Warning Light
This warning light indicates when the
driver or passenger seat belt is
un
buckled. When the ignition is first
placed in the ON/RUN or ACC/ON/RUN
position and if the driver’s seat belt is unbuckled,
a chime will sound and the light will turn on. When
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime
will sound
Ú page 151.
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.
This indicates a possible problem with the
e l

ectrical system or a related component.
Door Open Warning Light
This indicator will illuminate when a door
is ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single
c h
ime.
Electric Power Steering Fault Warning
Light
This warning light will turn on when
there's a fault with the Electric Power
St
eering (EPS) system Ú page 92.
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
indicate a problem with the ETC system.
I
f
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
p e
dals are pressed at the same time. If the light continues to flash when the vehicle is
r
u

nning, 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
e n
gine 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
a n

d 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 190.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.3

GETTING TO KNOW YOUR INSTRUMENT PANEL 79
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
sy

stem 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.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an 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
Ú page 121.
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
th

e 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.
Normally, the OBD II system will be ready. The
OBD II system may n
ot
be ready if your vehicle was
recently serviced, recently had a dead 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,
w h

ich 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, b
ut do not crank or start the engine.

NOTE:
If you crank or start the engine, you will have to
s t
art this test over.
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.
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, infor -
mation stored in your vehicle systems,
i n
cluding personal information.

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 t
hings 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 illuminated until you place the ignition
in the off position 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 above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
i s

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.

STARTING AND OPERATING 83
NOTE:
For Keyless Enter ‘n Go™ equipped vehicles, the
e n
gine will turn off and the ignition switch will
change to ACC Mode.
If the vehicle is not in PARK and the driver exits the
v e

hicle with the engine running, the vehicle may
AutoPark.
AutoPark will engage when all of these conditions
a r

e met:
Vehicle is equipped with a rotary selector and an
eight speed transmission
Vehicle is not in PARK
Vehicle speed is 1.2 mph (1.9 km/h) or less
Driver’s seat belt is unbuckled
Driver’s door is ajar
Brake pedal is not pressed
The message “ Au
toPark Engaged Shift to P then
Shift to Gear ” will display in the instrument cluster.
NOTE:
In some cases the ParkSense graphic will be
d i
splayed in the instrument cluster. In these cases,
the gear selector must be returned to “P” to select
desired gear.
If the driver shifts into PARK while moving, the
ve
hicle may AutoPark.
AutoPark will engage ON
LY when vehicle speed is
1.2 mph (1.9 km/h) or less. The message “
Ve
hicle Speed is Too High to Shift to
P” will be displayed in the instrument cluster if
vehicle speed is above 1.2 mph (1.9 km/h).
ALWAYS DO A VISUAL CHECK
that your vehicle is in
PARK by looking for the “P” in the instrument
cluster display and near the gear selector. As an
added precaution, always apply the parking brake
when exiting the vehicle.
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” or “Cold Weather Operation”
procedure, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there.
Crank the engine for no more than 15 seconds.
This should clear any excess fuel in case the
engine is flooded. Leave the ignition key in the RUN
position, release the accelerator pedal and repeat
the “Normal Starting” procedure.
WARNING!

If vehicle speed is above 1.2
mph (1.9 km/h), the
tr
ansmission will default to NEUTRAL until the
vehicle speed drops below 1.2 mph (1.9 km/h). A
ve

hicle left in the NEUTRAL position can roll. As an
added precaution, always apply the parking brake
when exiting the vehicle.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
w a

y. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly

FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:
This system may take some time to return to full
f u
nctionality after a battery disconnect.
POWER STEERING
The Electric Power Steering system will give you
good vehicle response and increased ease of
maneuverability in tight spaces. The system will
vary its assist to provide light efforts while parking
and good feel while driving. If the electric steering
system experiences a fault that prevents it from
providing assist, you will still have the ability to
steer the vehicle manually. Alternate electric power steering efforts can be
s
e

lected through the Uconnect system
Ú page 122.
If the Electric Power Steering Fault
Warning Light is displayed and the
“ S

ERVICE POWER STEERING” or the
“POWER STEERING ASSIST OFF –
SERVICE SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for service
Ú page 71.
NOTE:

Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substan
-
tial increase in steering effort, especially at low
s p

eeds and during parking maneuvers.

If the condition persists, see an authorized
dealer for service.
If the Electric Power Steering Fault Warning Light is
di
splayed and the “POWER STEERING SYSTEM
OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that
extreme steering maneuvers may have occurred
which caused an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the Electric Power Steering Fault
Warning Light and message turn off.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control system takes
over accelerator operations at speeds greater than
25 mph (40 km/h), or 20 mph (32 km/h)
de

pending on engine size and axle ratio.
