To Unlock From The Passenger Side
With a valid Passive Entry key fob within 5 ft
(1.5 m) of the passenger door handle, grab
the front passenger door handle to unlock all
four doors and the liftgate automatically.
NOTE:
All doors will unlock when the front
passenger door handle is grabbed regardless
of the driver’s door unlock preference setting
(“Unlock Driver Door 1st Press” or “Unlock
All Doors 1st Press”).
Preventing Inadvertent Locking Of Passive
Entry Key Fob In Vehicle (FOBIK-Safe)

To minimize the possibility of unintentionally
locking a Passive Entry key fob inside your
vehicle, the Passive Entry system is equipped
with an automatic door unlock feature which
will function if the ignition is OFF.

FOBIK-Safe only executes in vehicles with
Passive Entry. There are three situations that
trigger a FOBIK-Safe search in any Passive
Entry vehicle:
A lock request is made by a valid Passive
Entry key fob while a door is open.
A lock request is made by the Passive
Entry door handle while a door is open.
A lock request is made by the door panel
switch while the door is open.
When any of these situations occur, after all
open doors are shut, the FOBIK-Safe search
will be executed. If it finds a Passive Entry
key fob inside the car, the car will unlock and
alert the customer.
NOTE:
The vehicle will only unlock the doors when
a valid Passive Entry key fob is detected
inside the vehicle. The vehicle will not
unlock the doors when any of the following
conditions are true:
The doors are manually locked using the
door lock knobs.
If a paired key fob is found outside of the
vehicle, FOBIK-Safe will not activate.
Three attempts are made to lock the doors
using the door panel switch and then close
the doors.
If the liftgate is opened and then all four
doors are locked, the key fob will become
locked in the vehicle if the liftgate is
closed and will not alert the customer. To Unlock/Enter The Liftgate
With a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate, push the Passive
Entry button located to the left of the liftgate
release handle to open the liftgate with one
fluid motion.
To Lock The Liftgate
NOTE:
Always take the key with you once a door or
the liftgate is locked to prevent locking the
key fob inside of the vehicle. If the key has
been locked inside of the vehicle, it can be
recovered using the second provided key fob.
With a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate, push the Passive
Entry button located to the left of the liftgate
release handle.
NOTE:
The liftgate passive entry lock button will
lock all doors and the liftgate.

uted over the cargo area.
Crossbars should always be used whenever
cargo is placed on the roof rack. Check the
straps frequently to be sure that the load
remains securely attached.
NOTE:
Crossbars can be purchased at an authorized
dealer through Mopar parts.
External racks do not increase the total load
carrying capacity of the vehicle. Be sure that
the total occupant and luggage load inside
the vehicle, plus the load on the luggage
rack, do not exceed the maximum vehicle
load capacity.
WARNING!
To avoid serious injury or death:
Do not insert any objects into the recep -
tacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause
an electric shock and failure.
WARNING!
Cargo must be securely tied down before

ENVIRONMENTAL
PROTECTION SYSTEMS — IF
EQUIPPED
Gasoline Particulate Filter (GPF) — 2.0L T4
Petrol Versions Only
The Gasoline Particulate Filter is a mechan-
ical filter, integral to the exhaust system,
which physically traps carbon particles
present in the exhaust gases of 2.0L T4
petrol engines.
The particulate filter is needed to eliminate
almost all carbon particle emissions in
compliance with current/future regulations
and standards. Since this filter physically traps particulates,
it must be cleaned (regenerated) during
normal driving operation to remove carbon
particles. The regeneration procedure is
controlled automatically by the engine
control unit according to the filter conditions
and car use conditions.
The following may occur during regeneration:
increased levels of noise vibration and harsh
-
ness (NVH) and reduced engine perfor -
mance.
Dedicated messages can appear in the
instrument cluster display as a result of the
condition of the filter. Refer to the opening
paragraph of the "Warning Lights And
Messages" section for further information.
Travel at reduced speeds and turn
corners carefully when carrying large or
heavy loads on the roof rack. Wind
forces, due to natural causes or nearby
truck traffic, can add sudden upward
loads. It is recommended to not carry
large flat loads, such as wood panels or
surfboards, which may result in damage
to the cargo or your vehicle.
Load should always be secured to cross
bars first, with tie down loops used as
additional securing points if needed. Tie
loops are intended as supplementary tie
down points only. Do not use ratcheting
mechanisms with the tie loops. Check
the straps frequently to be sure that the
load remains securely attached.
