NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized 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 ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine. NOTE:
A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, 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 Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try 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 sec-
onds), 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.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:If the RKE transmitter is equipped with a screw,
reinstall and tighten the screw until snug.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
How to Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed

(BeltAlert) will alert the driver or front passenger to
buckle the seat belt. The driver should also instruct all
other occupants to buckle their seat belts. Once the
warning is triggered, BeltAlertwill continue to chime
and flash the Seat Belt Reminder Light for 96 seconds or
until the driver ’s or front passenger ’s seat belt is buckled.
BeltAlert will be reactivated if the driver ’s or passen-
ger ’s seat belt is unbuckled for more than 10 seconds and
the vehicle speed is greater than 5 mph (8 km/h).
For front passenger seats equipped with BeltAlert, your
vehicle is equipped to detect when it is occupied. The
BeltAlert warning system is not activated when the
front passenger seat is unoccupied. The BeltAlert warn-
ing system may be triggered when an animal or heavy
object is on the front passenger seat or when the seat is
folded flat (if equipped). It is recommended that pets be
restrained in the rear seat in pet harnesses or pet carriers
that are secured by seat belts and cargo is properly
stowed. BeltAlert
can be enabled or disabled by your authorized
dealer or by following these steps:
NOTE: The following steps must occur within the first
60 seconds of the ignition switch being turned to the ON
or START position. Chrysler Group LLC does not recom-
mend deactivating BeltAlert.
1. Turn the ignition switch to the OFF position, and
buckle the driver’s seat belt.
2. Turn the ignition key to the ACC/ON position (do not
start the engine), and wait for the Seat Belt Reminder
Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle
and then re-buckle the driver’s seat belt at least three
times within 10 seconds, ending with the seat belt
buckled.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ORC determines if a side collision requires the
side airbags to inflate based on the severity and type of
collision.
Based on the severity and type of collision, the side
airbag inflator on the crash side of the vehicle is trig-
gered, releasing a quantity of non-toxic gas. The inflating
side airbag exits through the seat seam into the space
between the occupant and the door. The side airbags fully
inflate in about 10 milliseconds. The side airbag moves at
a very high speed and with such a high force, that it
could injure you if you are not seated properly, or if items
are positioned in the area where the side airbag inflates.
This especially applies to children.
•The Knee Impact Bolsters help protect the knees of
the driver and the front passenger, and position front
occupants for the best interaction with the Advanced
Front Airbag.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
If a Deployment Occurs
The front airbags are designed to deflate immediately
after deployment.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Vary the Speed Setting
When the Electronic Speed Control is set, you can in-
crease speed by pushing up and holding the RESUME
ACCEL lever. If the lever is continually held in the
RESUME ACCEL position, the set speed will continue to
increase until the lever is released, then the new set speed
will be established.
Tapping RESUME ACCEL once will result ina1mph
(1.6 km/h) speed increase. Each time the Electronic
Speed Control lever is tapped, speed increases so that
tapping the Electronic Speed Control lever three times
will increase speed by 3 mph (4.8 km/h), etc.
To decrease speed while the Electronic Speed Control is
set, push down and hold the SET DECEL lever. If the
lever is continually held in the SET DECEL position, the
set speed will continue to decrease until the lever is
released. Release the lever when the desired speed is
reached, and the new set speed will be established.Tapping the SET DECEL lever once will result ina1mph
(1.6 km/h) speed decrease. Each time the lever is tapped,
speed decreases.
Manual Transmission
Pressing the clutch pedal will disengage the Electronic
Speed Control. A slight increase in engine RPM before the
Electronic Speed Control disengages is normal.
Vehicles equipped with manual transmissions may need
to be shifted into a lower gear to climb hills without
speed loss.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge and temperature gauge may not show accu-
rate readings. When the engine is not running, turn the
ignition switch to ON to obtain accurate readings.
2. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON, and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer. If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
3. Front Fog Light Indicator — If Equipped

damaged, a “noFUSE” message will display in the odom-
eter display area. For further information on fuses and
fuse locations refer to “Fuses” in “Maintaining Your
Vehicle”.CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 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 you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument

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 or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
26. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this 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 your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.

WARNING!
If a warning light remains on the system may not be
working and you will not have the benefit of ESP or
BAS. Under certain driving conditions, where ESP or
BAS would be beneficial, you - if you have not
adjusted your driving speeds and stopping in or to
account for the lack of the feature, may be in acci-
dent.
30. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash
depending on the nature of the problem. Cycle the
ignition key when the vehicle is safely and completely
stopped and the shift lever is placed in the PARK
position. The light should turn off. If the light remains on with the engine running, your vehicle will usually be
drivable; however, see an authorized dealer for service as
soon as possible.
If the light continues to flash when the engine 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 first turned ON and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
