KEYS
Key Fob
Your vehicle uses a keyless ignition system. The
ignition system consists of a key fob and a
START/STOP push button ignition system. The
Remote Keyless Entry (RKE) system consists of
a key fob and Keyless Enter-N-Go feature.
NOTE:
The key fob may not be found if it is located next
to a mobile phone, laptop or other electronic
device; these devices may block the key fob’s
wireless signal.
The key fob allows you to lock or unlock all
doors, tailgate, and the RamBox (if equipped),
as well as release the tailgate, and activate the
Panic Alarm from distances up to approximately
66 ft (20 m). The key fob does not need to be
pointed at the vehicle to activate the system. NOTE:
In the ON/RUN position, all key fob buttons
will work until the vehicle reaches 2 mph
(4 km/h).
The key fob should not be placed next to the
wireless charging pad (if equipped).

Key Fob
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or fully depleted battery. A low key fob battery
can be verified by referring to the instrument
cluster, which will display directions to follow.
In a situation where the battery is low or fully
depleted, a back up method can be used to
operate the ignition switch. Put the nose side of
the key fob (side opposite of the emergency key)
against the START/STOP ignition button and
push to operate the ignition switch.
To Unlock The Doors And Tailgate
Push and release the unlock button on the key
fob once to unlock the driver’s door. Push the
unlock button twice within five seconds to
unlock all doors, the tailgate and the RamBox (if
equipped). The turn signal lights will flash to
acknowledge the unlock signal. The illuminated
entry system will also turn on.
NOTE:
All doors can be programmed to unlock on the
first push of the unlock button. Refer to “Ucon
-
nect Settings” in “Multimedia” for further infor -
mation.

Battery Saver On/Battery Saver Mode
Message — Electrical Load Reduction
Actions — If Equipped
This vehicle is equipped with an Intelligent
Battery Sensor (IBS) to perform additional moni -
toring 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.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster.
These messages indicate the vehicle battery
has a low state of charge and continues to lose
electrical charge at a rate that the charging
system cannot sustain.
