All Wheel Drive (AWD) Status — If Equipped
The instrument cluster display will normally display
the main menu or the screens of a selected feature
of the main menu. The main display area also
displays “pop-up” messages that consist of
approximately 60 possible warning or information
messages. These pop-up messages fall into
several categories:
Five Second Stored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Most of the messages of
this type are then stored (as long as the condi-
tion that activated it remains active) and can be
reviewed from the “Messages” main menu item.
Examples of this message type are “Right Front
Turn Signal Lamp Out” and “Low Tire Pressure.”
Unstored Messages
This message type is displayed indefinitely or
until the condition that activated the message is
cleared. Examples of this message type are
“Turn Signal On” (if a turn signal is left on) and
“Lights On” (if driver leaves the vehicle with the
lights on).
Unstored Messages Until RUN
These messages deal primarily with the Remote
Start feature. This message type is displayed
until the ignition is in the RUN state. Examples of
this message type are “Remote Start Canceled -
Door Ajar” and “Press Brake Pedal and Push
Button to Start.”
Five Second Unstored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. An example of this
message type is “Automatic High Beams On.”
ENGINE OIL LIFE RESET
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required”
message will display in the instrument cluster
display for five seconds after a single chime has
sounded, to indicate the next scheduled oil change
interval. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate, dependent upon
your personal driving style.
Unless reset, this message will continue to display
each time the ignition is placed in the ON/RUN
position. To turn off the message temporarily, push
and release the OK or arrow buttons. To reset the
oil change indicator system (after performing the
scheduled maintenance), refer to the following

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
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.

Vehicle Security Warning Light —
If Equipped
This light will flash at a fast rate for
approximately 15 seconds when the
vehicle security system is arming, and
then will flash slowly until the vehicle is
disarmed.
YELLOW WARNING LIGHTS
Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (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.
Electronic Stability Control (ESC) Active
Warning Light
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light in the instrument cluster will come
on when the ignition is placed in the
ON/RUN or ACC/ON/RUN position, and when ESC
is activated. It should go out with the engine
running. If the ESC Indicator Light comes on
continuously with the engine running, a
malfunction has been detected in the ESC system.
If this warning light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diagnosed
and corrected.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.

GETTING TO KNOW YOUR INSTRUMENT PANEL95
The ESC OFF Indicator Light and the ESC Indi-
cator Light come on momentarily each time the
ignition is placed in the ON/RUN or ACC/ON/
RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.
Electronic Stability Control (ESC) OFF
Warning Light
This warning light indicates the ESC is off.
Each time the ignition is turned to
ON/RUN or ACC/ON/RUN, the ESC
system will be on, even if it was turned off
previously.
Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low
Ú page 270.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

21_WD_OM_EN_USC_t.book Page 95

96GETTING TO KNOW YOUR INSTRUMENT PANEL
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Low Fuel Warning Light
When the fuel level reaches
approximately 2 gal (7.5 L), this light will
turn on and a chime will sound. The light
will remain on until fuel is added.
Anti-Lock Brake System (ABS) Warning
Light
This warning light monitors the ABS. The
light will turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN
position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is required as
soon as possible. However, the conventional brake
system will continue to operate normally,
assuming the Brake Warning Light is not also on.
If the ABS light does not turn on when the ignition
is placed in the ON/RUN or ACC/ON/RUN position,
have the brake system inspected by an authorized
dealer.
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 199.
Service Adaptive Cruise Control (ACC)
Warning Light — If Equipped
This light will turn on when the ACC is not
operating and needs service
Úpage 121.
Service AWD Warning Light — If Equipped
This telltale will turn on to indicate the All
Wheel Drive (AWD) system is not
functioning properly and that service is
required. Contact an authorized dealer.
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.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

GETTING TO KNOW YOUR INSTRUMENT PANEL99
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 158.
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,
including personal information.

STARTING AND OPERATING107
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK (P) before the ignition can be turned to the
OFF mode. This helps the driver avoid inadvertently
leaving the vehicle without placing the
transmission in PARK. This system also locks the
transmission in PARK whenever the ignition is in
the OFF mode.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC mode)
before exiting the vehicle.
BRAKE TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed. The
brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle
is stopped or moving at low speeds.
FUEL ECONOMY (ECO) MODE
The Fuel Economy (ECO) mode can improve the
vehicle's overall fuel economy during normal
driving conditions. Push the ECO button in the
center stack of the instrument panel to activate or
disable ECO mode. A light on the button indicates
when ECO mode is disabled.

ECO OFF Button

When the Fuel Economy (ECO) Mode is enabled,
the vehicle control systems will change the
following:
The transmission will upshift sooner and
downshift later.
The overall driving performance will be more
conservative.
Some ECO mode functions may be temporarily
inhibited based on temperature and other
factors.
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
mode. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
Shift into or out of PARK or REVERSE (R) only
after the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE (D) when the engine is
above idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
