SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system will shut the engine off in two seconds if an
invalid key fob is used to start the engine.
After placing the ignition switch 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 used an invalid key fob to start the
engine. Either of these conditions will result in the
engine being 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
Ú
page 312.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button as long as
the key fob is in the passenger compartment.
The START/STOP ignition button has several
operating modes that are labeled and will
illuminate when in position. These modes are OFF,
ACC, ON/RUN, and START.
START/STOP Ignition Button

The push button ignition can be placed in the
following modes:
OFFThe engine is stopped
Some electrical devices (e.g. power locks,
alarm, etc.) are still available
ACC
Engine is not started
Some electrical devices are available (e.g.
power windows, etc.)
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket Remote Start
systems. Use of these systems may result in
vehicle starting problems and loss of security
protection.

POWER INVERTER — IF EQUIPPED
There is a 115 Volt, 150 Watt inverter outlet
located on the back of the center console to
convert DC current to AC current. This outlet can
power cellular phones, electronics and other low
power devices requiring power up to 150 Watts.
Certain video game consoles exceed this power
limit, as will most power tools.
Power Inverter
The power inverter is designed with built-in
overload protection. If the power rating of
150 Watts is exceeded, the power inverter
automatically shuts down. Once the electrical
device has been removed from the outlet the
inverter should automatically reset. To avoid
overloading the circuit, check the power ratings on
electrical devices prior to using the inverter.
WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while driving
the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in draw
power from the vehicle's battery, even when
not in use (i.e., cellular phones, etc.). Eventu
-
ally, if plugged in long enough, the vehicle's
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.) will
degrade the battery even more quickly. Only
use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the generator to recharge the vehicle's
battery.
CAUTION!
WARNING!
To avoid serious injury or death:
Do not insert any objects into the receptacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause an
electric shock and failure.

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.
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 186.
WARNING!
A malfunctioning catalytic converter 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.

23_WD_OM_EN_USC_t.book Page 92

96GETTING TO KNOW YOUR INSTRUMENT PANEL
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 153.
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.

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.

23_WD_OM_EN_USC_t.book Page 96

GETTING TO KNOW YOUR INSTRUMENT PANEL97
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 previously mentioned 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.3
