(Continued)
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 ignition keys which have an
embedded electronic chip (transponder) to
prevent unauthorized vehicle operation.
Therefore, only keys that are programmed to
the vehicle can be used to start and operate the
vehicle.
If the vehicle security light is on after the key is
placed in the MAR (ACC/ON/RUN) position, it
indicates that there is a problem with the
electronics.
All of the keys provided with your new vehicle
have been programmed to the vehicle
electronics.NOTE:
A key which 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
Ú
page 265.
IGNITION SWITCH

1. Place the gear selector in PARK.

2. Rotate the key to the STOP (OFF/LOCK)
position.
3. Remove the key from the ignition switch lock cylinder.

Ignition Switch Positions

CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
1 — STOP (OFF/LOCK)
2 — MAR (ACC/ON/RUN)
3 — AVV (START)
WARNING!
Before exiting a vehicle, always shift the
transmission into PARK, apply the parking
brake, and remove the key fob from the
vehicle. When leaving the vehicle, always
lock your vehicle. In case you switch off the
vehicle and the transmission is not in
PARK, a warning message will appear on
the cluster which suggests you to shift the
transmission into PARK and, then, you can
remove the key within 15 seconds. If
15 seconds expire, you have to rotate the
key from the OFF/LOCK position to the ON/
RUN position and come back to the OFF/
LOCK position in order to remove the key.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 gear selector.

Values Displayed
Range
This indicates the distance which may be
traveled with the fuel remaining in the tank,
assuming that driving conditions will not
change. The message “----” will appear on the
display in the following cases:
Distance less than 30 miles (or 50 km).
The vehicle is parked for a long time with the
engine running.
NOTE:
The range depends on several factors: driving
style, type of route (freeway, residential, moun -
tain roads, etc.), conditions of use of the vehicle
(load, tire pressure, etc.). Trip planning must
take into account the above notes.
Travel Distance
This value shows the distance covered since the
last reset.
Average Fuel Consumption
This value shows the approximate average
consumption since the last reset.
Current Fuel Consumption
This indicates the fuel consumption. The value
is constantly updated. The message “----” will
appear on the display if the vehicle is parked
with the engine running.
Average Speed
This value shows the vehicle's average speed as
a function of the overall time elapsed since the
last reset.
Travel Time
This value shows the time elapsed since the last
reset.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedicated
message and/or acoustic signal when
applicable. These indications are indicative and
precautionary and as such must not be
considered as exhaustive and/or alternative to
the information contained in the Owner’s
Manual, which you are advised to read carefully
in all cases. Always refer to the information in
this chapter in the event of a failure indication.
All active telltales will display first if applicable.
The system check menu may appear different based upon equipment options and current
vehicle status. Some telltales are optional and
may not appear.
Red Warning Lights
Air Bag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the
ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is
either not on during startup, stays on, or turns
on while driving, have the system inspected by
an authorized dealer as soon as possible. This
light will illuminate with a single chime when a
fault with the Air Bag Warning Light has been
detected, it will stay on until the fault is cleared.
If the light comes on intermittently or remains
on while driving, have an authorized dealer
service the vehicle immediately.
Brake Warning Light
This warning light monitors various
brake functions, including brake fluid
level and parking brake application. If
the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a
problem with the Anti-Lock Brake System
reservoir.

21_VM_OM_EN_USC_t.book Page 49

50GETTING TO KNOW YOUR INSTRUMENT PANEL
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system
malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability
Control (ESC) system. In this case, the light will
remain on until the condition has been
corrected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected. NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Electronic
Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn
on along with the ABS Light. Immediate repair to
the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
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 electrical system or a related
component.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.

52GETTING TO KNOW YOUR INSTRUMENT PANEL
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, 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 153.
Transmission Fault Warning Light
This light will illuminate (together with
a message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Oil Level Warning Light
This warning light appears on the
panel when the engine oil level falls
below the minimum recommended
value. Restore the correct engine oil
level or contact your authorized dealer for
service.
Yellow Warning Lights
Anti-Lock Brake System (ABS) Warning Light
This light monitors the ABS. The light
will turn on when the ignition is placed
in the ON/RUN or MAR/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. However, the conventional brake system will continue to operate normally if the
brake warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light
does not turn on when the ignition is placed in
the ON/RUN or MAR/ON/RUN position, have
the light inspected by an authorized dealer.
Low Fuel Warning Light
When the fuel level reaches
approximately 2–3 gal (9–11 L) this
light will turn on, and remain on until
fuel is added.
Generic Warning Light
The Generic Warning Light will
illuminate if any of the following
conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure,
Parking Sensor Failure, Fuel Cut-Off Fail/
Intervention, Generic Failure on Trailer, or Air
Bag telltale recovery.
The telltale will blink in case of an Air Bag
Warning Light Failure. Contact an authorized
dealer immediately for service.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning Light
is illuminated you could cause the fluid to boil
over, come in contact with hot engine or
exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission
damage or transmission failure.

60STARTING AND OPERATING

1. Locate the engine block heater cord
(behind the driver’s side headlamp).

2. Undo the hook-and-loop strap that secures the heater cord in place.
3. Pull the cord to the front of the vehicle and plug it into a grounded, three-wire extension
cord.
4. After the vehicle is running, reattach the cord to the hook-and-loop strap and
properly stow away behind the driver’s side
headlamp.
NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from an
authorized Mopar dealer.
The engine block heater will require 110 Volts
AC and 6.5 Amps to activate the heater
element.
The engine block heater must be plugged in
at least one hour to have an adequate
warming effect on the engine.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contributes
to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with
anticipated climate conditions under which
vehicle operations will occur. For the
recommended viscosity and quality grades
Ú page 259. NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera
-
tion. This should be considered a normal part of
the break-in and not interpreted as a concern.
Please check your oil level with the engine oil
indicator often during the break in period. Add
oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave an automatic transmission in PARK.
The parking brake lever is located in the center
console. To apply the parking brake, pull the
lever up as firmly as possible. To release the
parking brake, pull the lever up slightly, push
the center button, then lower the lever
completely.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
