GETTING TO KNOW YOUR INSTRUMENT PANEL97
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
system 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 driveable 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 156.
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,
information stored in your vehicle
systems, including personal information.

98GETTING TO KNOW YOUR INSTRUMENT PANEL
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
the 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 not be ready if your vehicle
was recently serviced, recently had a depleted
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,
which 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,
but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to
start this test over.
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 things 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
is 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.

104STARTING AND OPERATING
(Continued)
(Continued)
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Never use the PARK (P) position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK without blinking.
Ensure that the vehicle is completely stopped,
and the PARK position is properly indicated,
before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL (N) if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the
ignition is in the OFF position, the transmis -
sion is locked in PARK, securing the vehicle
against unwanted movement.
WARNING!
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ACC or ON/RUN
position. A child could operate power
windows, other controls, or move the vehicle.
WARNING!

108STARTING AND OPERATING
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode Ú page 108). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the
transmission gear, and will display the current gear
in the instrument cluster as 1, 2, 3, etc.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the
engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer):

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible. If not, shift the transmission to
NEUTRAL (N).
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
In AutoStick mode, you can use the gear selector
(in the MANUAL position), or the paddle shifters to
the MANUAL (M) position (beside the DRIVE (D)
position), or tap one of the paddle shifters on the
steering wheel. Tapping the (-) paddle shifter to
enter AutoStick mode will downshift the
transmission to the next lower gear, while
tapping (+) to enter AutoStick mode will retain the
current gear. The current transmission gear will be
displayed in the instrument cluster.
NOTE:The paddle shifters (if equipped) may be disabled
using the Uconnect Personal Settings.

110STARTING AND OPERATING

AWD Control Switch

This electronically shifted transfer case provides
three positions:
All-wheel drive auto range (AWD AUTO)
All-wheel drive low range (AWD LOW)
N (Neutral)
When additional traction is required, the transfer
case AWD LOW position can be used to lock the
front and rear driveshafts together forcing the front
and rear wheels to rotate at the same speed. This
is accomplished by pushing the AWD LOW switch
Ú page 111. The AWD LOW position is designed for
loose, slippery road surfaces only. Driving in the
AWD LOW position on dry, hard surfaced roads
may cause increased tire wear and damage to the
driveline components.
Transfer Case Position Indicator Messages
The Transfer Case Position Indicator message
(AWD LOW) is located in the instrument cluster and
indicate the current and desired transfer case
selection Ú page 81. When you select a different
transfer case position, the position indicator lights
will do the following:
If All Shift Conditions Are Met:

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If shift conditions are not met, one or more of the
following events may occur:

1. The indicator light for the current position will remain on.

2. The newly selected position indicator light will continue to flash.
3. The transfer case will not shift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met Úpage 111.
The SERV AWD Warning Light monitors the
electronic shift all-wheel drive system. If this light
remains on after engine start-up or illuminates
during driving, it means that the all-wheel drive
system is not functioning properly and that service
is required.
NOTE:Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in AWD LOW, the
engine speed is approximately three times that of
the AWD AUTO position at a given road speed. Take
care not to overspeed the engine and do not
exceed 25 mph (40 km/h).
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD” Warning
Light is illuminated. Not engaging the parking
brake may allow the vehicle to roll which may
cause personal injury.

22_WD_OM_EN_USC_t.book Page 110

114STARTING AND OPERATING
7. New brake pads installed on old rotors require a burnish. New rotors installed with old brake
pads should be burnished at the track or
driven for 300 miles (485 km) of city driving to
develop an adequate lining transfer layer on
the rotor surface prior to track use.
8. Rotors that pulsate during track use should be replaced.
NOTE:Resurfacing of the rotors is not recommended, as
it removes mass from the rotor, reducing its
thermal capacity. Resurfacing also thins the rotor
cheek, making it less robust and increasing the
likelihood of pulsation in further track use.
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.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions and adjusts
accordingly.
Alternate electric power steering efforts can be
selected through the Uconnect System
Úpage 156.
If the Electric Power Steering warning icon is
displayed and the “SERVICE 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 89.
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
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, this
indicates 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 icon and message turn off.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or
pressing the accelerator pedal will automatically
re-start the engine.
This vehicle has been upgraded with a heavy duty
starter, enhanced battery, and other upgraded
engine parts, to handle the additional engine
starts.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

yellow Stop/Start telltale will appear in the
instrument cluster display Ú page 89.
If the “SERVICE STOP/START SYSTEM” message
appears in the instrument cluster display, have the
system checked by an authorized dealer.
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 takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.

Cruise Control Buttons

1 — On/Off
2 — CANC/Cancel
3 — SET (+)/Accel
4 — RES/Resume

22_WD_OM_EN_USC_t.book Page 116

124STARTING AND OPERATING
In these cases, the instrument cluster display will
display the above message and the system will
deactivate.
This message can sometimes be displayed while
driving in highly reflective areas (i.e. ice and snow,
or tunnels with reflective tiles). The ACC system will
recover after the vehicle has left these areas.
Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the center of the vehicle behind the lower grille.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snowplow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display, and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily blinded due to obstructions, such as mud, dirt, or
ice on windshield and fog on the inside of glass. In
these cases, the instrument cluster display will
read “ACC/FCW Limited Functionality Clean Front
Windshield” and the system will have degraded
performance.
This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward facing camera inspected at an authorized
dealer.

22_WD_OM_EN_USC_t.book Page 124

STARTING AND OPERATING125
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
display reads “ACC/FCW Unavailable Service
Required” or “Cruise/FCW Unavailable Service
Required”, there may be an internal system fault or
a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable
under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
ACC while towing a trailer is recommended only
with an Integrated Trailer Brake Controller.
Aftermarket trailer brake controllers will not
activate the trailer brakes when ACC is braking.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no vehicle in
front detected. Once the vehicle is out of the curve
the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.
ACC Hill Example

STARTING AND OPERATING131
Front Park Assist Audible Alerts
ParkSense will turn off the Front Park Assist
audible alert (chime) after approximately three
seconds when an obstacle has been detected, the
vehicle is stationary, and brake pedal is applied.
Adjustable Chime Volume Settings
Front and Rear chime volume settings can be
selected from the Uconnect system
Ú page 156.
The chime volume settings include low,
medium, and high.
ParkSense will retain its last known configura -
tion state through ignition cycles.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú page 81. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
The ParkSense Warning screen will only be
displayed if Sound and Display is selected from the
Customer Programmable Features section of the
Uconnect system Ú page 156.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled
with the ParkSense switch.
When the ParkSense switch is pushed to disable
the system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately five
seconds. When the gear selector is moved to
REVERSE and the system is disabled, the
instrument cluster display will display the
“PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
NOTE:When ParkSense is disabled and the gear selector
is moved to the DRIVE position, no warning
message will be displayed.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service. The
ParkSense switch LED will be off when the system
is enabled. If the ParkSense switch is pushed, and
the system requires service, the ParkSense switch
LED will blink momentarily, and then the LED will
be on.
OPERATION WITH A TRAILER
For vehicles equipped with an Integrated Trailer
Brake Module (ITBM), the operation of the rear
sensors is automatically deactivated when the
trailer's electric plug is inserted in the vehicle's tow
hook socket. The front system is still functional,
and the arcs will be overlaid with a “Trailer”
message. The rear sensors are automatically
reactivated when the trailer's cable plug is
removed.
When the vehicle is connected to a trailer, the
instrument cluster display will show the "Rear
ParkSense Unavailable Trailer Connected"
message in the following situations:
For five seconds at vehicle start up
For five seconds when the ParkSense button is
pushed, as long as an object is not detected in
the front
As long as the vehicle is in REVERSE (vehicle
graphic displayed with a trailer overlay)
NOTE:For more information on the Integrated Trailer
Brake Module, see Ú page 145.
For vehicles not equipped with ITBM, the
automatic braking may falsely be applied if a trailer
is hooked up, and Park Assist is not manually
deactivated. It is also possible, the trailer may be
mistaken as a close object.
