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
turned to 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 274.
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 mechanical ignition switch.
Mechanical 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 — AVV (START)
2 — MAR (ACC/ON/RUN)
3 — STOP (OFF/LOCK)
WARNING!
Before exiting a vehicle, always shift the
automatic transmission into PARK, apply
the parking brake, turn the vehicle OFF,
remove the key fobs from vehicle, and lock
your vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.

21_VF_OM_EN_USC_t.book Page 12

GETTING TO KNOW YOUR VEHICLE13
NOTE:
Opening the driver's door when the key is in the
ignition and the ignition switch position is STOP
(OFF/LOCK) sounds a signal to remove the key.
VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the
vehicle doors and ignition for unauthorized
operation. When the Vehicle Security system is
activated, interior switches for door locks are
disabled. The system provides both audible and
visible signals. For the first three minutes, the
horn will sound, and the turn signal lights will
flash. For an additional 15 minutes, only the
turn signal lights will flash.
TO ARM THE SYSTEM
To arm the system, the Vehicle Security system
will set when you use the key fob to lock the
doors. If a door or the hood is not properly shut,
the system will not be armed.
TO DISARM THE SYSTEM
Use the key fob to unlock the door and disarm
the system.
The Vehicle Security system will also disarm if a
programmed Sentry Key is inserted into the
ignition switch. To exit the alarming mode,
push the key fob unlock button, or insert a
programmed Sentry Key into the ignition switch. The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security system.
REARMING OF THE SYSTEM
If the system has not been disabled, the Vehicle
Security system will rearm itself after the 15
additional minutes of turn lamps flashing. If the
condition which initiated the alarm is still
present, the system will ignore that condition
and monitor the remaining doors and ignition.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm/disarm
if you lock/unlock the doors using the manual
door lock.
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.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren. A child could operate power windows,
other controls, or move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!

An unlocked vehicle is an invitation. Always
remove the key from the ignition and lock all
the doors when leaving the vehicle unattended.

seat could cause you to lose control. The
seat belt might not be adjusted properly
and you could be injured. Adjust the seat
only while the vehicle is parked.
Do not ride with the seatback reclined so
that the shoulder belt is no longer resting
against your chest. In a collision, you could
slide under the seat belt and be seriously or
even fatally injured. Use the recliner only
when the vehicle is parked.

GETTING TO KNOW YOUR VEHICLE19

If the driver or the passenger seats are not locked
in the facing forward position before the first
vehicle movement, shifting out of park is not
allowed until the seats are both locked in the
facing forward position. When the seats are not in
the right position and the first vehicle movement
after ignition START is attempted, a chime and a
message will appear in the instrument cluster
display. Rotate and lock the swivel seats in the
correct position before trying again.

If the driver or the passenger seats are not
locked in the facing forward position during
movement of the vehicle, a message will appear
in the instrument cluster display and an
intermittent chime will sound until key-off or
until the swivel seats are locked in the facing
forward position. Stop and move the swivel
seats in the correct position before proceeding.
If a fault is present in the system and it is not
possible to check the correct position of the
swivel seats, a message and the generic
warning light appears in the instrument cluster
display to inform about the failure. In these
conditions, check the status of the swivel seats
and do not drive the vehicle until the swivel
seats are locked in the facing forward position.HEATED SEATS — IF EQUIPPED
On some models, the front driver and
passenger seats may be equipped with heaters
in both the seat cushions and seatbacks. The
controls for the front heated seats are located
on the lower outboard side of the seat.

Heated Seat Switch

Push the switch once to turn on the heated
seats. Push the switch a second time to shut the
heating elements off. NOTE:
Once a heat setting is selected, heat will be felt
within two to five minutes.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medica
-
tion, alcohol use, exhaustion or other phys -
ical condition must exercise care when
using the seat heater. It may cause burns
even at low temperatures, especially if
used for long periods of time.
Do not place anything on the seat or seat -
back that insulates against heat, such as a
blanket or cushion. This may cause the seat
heater to overheat. Sitting in a seat that has
been overheated could cause serious
burns due to the increased surface
temperature of the seat.

If it becomes difficult to see clearly in the display,
the camera may need to be cleaned. If snow, ice,
mud, or any foreign substance builds up on the
camera lens, clean the lens, rinse with water,
and dry with a soft cloth. Do not cover the lens.

Camera Location

OUTSIDE MIRRORS
To receive maximum benefit, adjust the outside
mirror(s) to center on the adjacent lane of traffic
with a slight overlap of the view obtained on the
inside mirror.
Outside Mirrors Folding Feature
All outside mirrors are hinged and may be
folded forward or rearward to avoid damage.
The hinges have three detent positions:
Full forward position
Full rearward position
Normal position
POWER MIRRORS — IF EQUIPPED
The power mirror controls are located on the
driver’s side door trim panel.
Power Mirror Controls

To adjust a mirror, turn the control knob toward
the left upper, left lower, right upper or right
lower mirror positions indicated by one of the
four arrows on the switch. Tilt the control knob
in the direction you want the mirror to move.
When you are finished adjusting the mirror, turn
the control to the center position “O” to prevent
accidentally moving a mirror.
NOTE:
If your vehicle is equipped with a power blind
spot mirror, you can adjust them when the
control knob is positioned to the lower arrows.
WARNING!
Vehicles and other objects seen in an outside
convex mirror will look smaller and farther
away than they really are. Relying too much
on side convex mirrors could cause you to
collide with another vehicle or other object.
Use your inside mirror when judging the size
or distance of a vehicle seen in a side convex
mirror.

NOTE:
Do not connect devices with power higher than
180 W to the socket. Do not damage the socket
by using unsuitable adapters.
Power Outlet Fuses — Under Hood
AUXILIARY SWITCHES — IF EQUIPPED
Your vehicle may be equipped with two auxiliary
switches located on the instrument panel to the
left of the steering column which can be used to
power various electronic devices. Connections
to the switches are found in the right central
pillar fuse panel at the base of the passenger
side B-pillar.
Auxiliary Upfitter Switches

Auxiliary Switch 1 is configured to constant
battery feed, while Auxiliary Switch 2 is
configured to ignition feed.
For further information on using the auxiliary
switches, please refer to the Ram Body Builders
Guide by accessing www.rambodybuilder.com
and choosing the appropriate links.
1 — F14 Fuse 20 Amp Yellow Front Power Outlet
2 — F09 Fuse 15 Amp Blue Rear Power Outlet
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.).
Eventually, 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 accesso -
ries, 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.
