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.

position at the windshield. The mirror installs on
the windshield button with a counterclockwise
rotation and requires no tools for mounting. The
mirror head can be adjusted up, down, left, and
right for various drivers. The mirror should be
adjusted to center on the view through the rear
window.

Lights (DRLs) will turn off. Also, if a turn signal is
activated, the DRL lamp on the same side of the
vehicle may turn off for the duration of the turn
signal activation. Once the turn signal is no
longer active, the DRL lamp will illuminate.
NOTE:
If allowed by law in the country in which the
vehicle was purchased, the Daytime Running
Lights can be turned on and off using the Ucon -

“Multimedia” for further information.
High/Low Beam Switch
Push the multifunction lever toward the instru-
ment panel to switch the headlights to high
beam. Pulling the multifunction lever back
toward the steering wheel will turn the low
beams back on, or shut the high beams off.
Automatic High Beam Headlamp Control —
If Equipped
The Automatic High Beam Headlamp Control
system provides increased forward lighting at
night by automating high beam control through
the use of a digital camera mounted on the
inside rearview mirror or forward facing camera.
This camera detects vehicle specific light and automatically switches from high beams to low
beams until the approaching vehicle is out of
view.
NOTE:
The Automatic High Beam Headlamp Control
can be turned on or off by selecting “ON”
under “Auto Dim High Beams” within your
Uconnect settings, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” for
further information.
Broken, muddy, or obstructed headlights and
taillights of vehicles in the field of view will
cause headlights to remain on longer (closer
to the vehicle). Also, dirt, film, and other
obstructions on the windshield or camera
lens will cause the system to function improp
-
erly.
To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter
Reduced High Beam Sensitivity Control (not
recommended), on vehicles equipped with
mirror controlled automatic high beams and
without the forward facing camera, toggle the
high beam lever six full on/off cycles within 10 seconds of placing the ignition in the ON
position. The system will return to the default
setting when the ignition is OFF.
If the windshield or Automatic High Beam Head -
lamp Control mirror is replaced, the mirror must
be re-aimed to ensure proper performance. See
a local authorized dealer.
To Activate

WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a
switch in the multifunction lever, and can only
be operated with the ignition in the ACC or ON/
RUN position. Turn the end of the lever to select
the desired wiper speed.

Windshield Wiper/Washer Switch
Rotate the end of the lever upward, to the first
detent past the intermittent settings for
low-speed wiper operation. Rotate the end of
the lever upward to the second detent past the
intermittent settings for high-speed wiper oper

ation.
Intermittent Wiper System
The intermittent feature of this system was
designed for use when weather conditions
make a single wiping cycle, with a variable
pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob
upward to the first detent.
The delay interval decreases as you rotate the
knob until it enters the low continual speed
position. The delay can be regulated from a
maximum of about 18 seconds between cycles,
to a cycle every one second. The delay intervals
will double in duration when the vehicle speed
is 10 mph (16 km/h) or less.
