reset.  If  the  power  rating  exceeds  approxi-
mately  170  Watts,  the  power  inverter  may
have to be reset manually.
Auxiliary Switches — If Equipped 
Four  auxiliary  switches  located  in  the  lower
switch  bank  of the  instrument  panel  can be
used to power various electrical devices. You
have the ability to configure the functionality
of  the  auxiliary  switches  via  the  Uconnect
settings.
All switches can be configured as follows:
Switch type operation:  Latching or Momentary
Power source: Battery or Ignition
Ability  to  hold  last  state  across  key  cycles:
On or Off Auxiliary Switches
NOTE:
Holding  last  state  conditions  are  met  when
switch  type  is  set  to  latching  and  power
source is set to ignition.
For  more  information,  refer  to  “Uconnect
Settings”  in  “Multimedia”  in  your  Owner’s
Manual.
For  the  connection  and  installation  of  your
electrical  devices  refer  to  your  authorized
dealership.
ROOF LUGGAGE RACK — IF 
EQUIPPED  
NOTE:
Roof  rack  applications  are  for  Hard  Top
models  ONLY.
The load carried on the roof, when equipped
with a luggage rack, must not exceed 100 lbs
(45 kg), this includes the weight of the cross -
bars, and  it  should  be  uniformly  distributed
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 receptacles.
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.

system determines that a forward collision is
probable,  the  driver  will  be  provided  with
audible  and  visual  warnings  as  well  as  a
possible  haptic  warning  in  the  form  of  a
brake jerk. 
If the driver does not take action based upon
these progressive warnings, then the system
will provide a limited level  of  active  braking
to  help  slow  the  vehicle  and  mitigate  the
potential  forward  collision.  If  the  driver
reacts  to  the  warnings  by  braking  and  the
system determines that the driver intends to
avoid  the  collision  by  braking  but  has  not
applied  sufficient  brake  force,  the  system
will  compensate  and  provide  additional
brake force as required.
If  a  FCW  with  Mitigation  event  begins  at  a
speed  below 32 mph  (52 km/h), the  system
may  provide  the  maximum  braking  possible
to mitigate the potential forward collision. If
the  Forward  Collision  Warning  with  Mitiga-
tion  event  stops  the  vehicle  completely,  the
system will hold  the vehicle at standstill for
two seconds and then release the brakes. FCW Message
When  the  system  determines  a  collision  with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
NOTE:
The minimum speed for FCW activation is
3 mph (5 km/h).
The  FCW  alerts  may  be  triggered  on  objects
other than vehicles such as guard rails or sign
posts  based  on  the  course  prediction.  This  is
expected  and  is  a  part  of  normal  FCW  activa-
tion and functionality.
It is unsafe to test the FCW system. To prevent
such  misuse  of  the  system,  after  four  Active
Braking  events  within  a  key  cycle,  the  Active Braking  portion  of  FCW  will  be  deactivated
until the next Key Cycle.
The  FCW  system  is  intended  for  on-road
use  only.  If  the  vehicle  is  taken  off-road,
the FCW system  should be deactivated to
prevent  unnecessary  warnings  to  the
surroundings.
FCW  may  not  react  to  irrelevant  objects
such  as  overhead  objects,  ground  reflec-
tions,  objects  not  in  the  path  of  the
vehicle,  stationary  objects  that  are  far
away, oncoming traffic, or leading vehicles
with the same or higher rate of speed.
FCW  will  be  disabled  like  ACC,  with  the
unavailable screens.
 WARNING!
Forward  Collision  Warning  (FCW)  is  not
intended  to  avoid  a  collision  on  its  own,
nor can FCW detect every type of potential
collision.  The  driver  has  the  responsibility
to  avoid  a  collision  by  controlling  the
vehicle via braking and steering. Failure to
follow  this  warning  could  lead  to  serious
injury or death.

Maintaining Your Air Bag System 
 WARNING!
Modifications  to  any  part  of  the  air  bag
system could cause it to fail when you need
it.  You  could  be  injured  if  the  air  bag
system  is  not  there  to  protect  you.  Do  not
modify  the  components  or  wiring,
including  adding  any  kind  of  badges  or
stickers  to  the  steering  wheel  hub  trim
cover  or  the  upper  passenger  side  of  the
instrument panel.  Do  not  modify  the  front
bumper,  vehicle  body  structure,  or  add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of
the  air  bag  system  yourself.  Be  sure  to
tell  anyone  who  works  on  your  vehicle
that it has an air bag system.
Do not attempt to modify any part of your
air  bag  system.  The  air  bag  may  inflate
accidentally or may not function properly
if  modifications  are  made.  Take  your
vehicle to an authorized dealer for any air
bag  system  service.  If  your  seat,
including  your  trim  cover  and  cushion,
needs  to  be  serviced  in  any  way
(including  removal  or  loosening/
tightening  of  seat  attachment  bolts),
take the vehicle to an authorized dealer.
Only  manufacturer  approved  seat
accessories  may  be  used.  If  it  is
necessary  to  modify  the  air  bag  system
for  persons  with  disabilities,  contact  an
authorized dealer.

Suitability of Passenger Seats for i-Size 
Child Restraint System Use
The  rear  outboard  seats  of  the  vehicle  are
type-approved  to  house  the  state-of-the-art
i-Size child restraint systems.
These  child  restraint  systems,  built  and
type-approved  according  to  the  i-Size  (ECE
R129) standard, ensure better safety condi-
tions to carry children on board a vehicle:
The  child  must  be  transported  rearward
facing until 15 months:
Child  restraint  system  protection  is
increased in the event of a side collision:
The use of the ISOFIX system is promoted
to  avoid  faulty  installation  of  the  child
restraint system:
Efficiency  in  the  choice  of  the  child
restraint  system,  which  isn't  made
according  to  weight  anymore  but
according  to  the  child's  height,  is
increased:
Compatibility  between  the  vehicle  seats
and  the  child  restraint  systems  is  better:
the  i-Size  child  restraint  systems  can  be
considered as "Super ISOFIX"; this means
that  they  can  be  perfectly  fitted  in
type-approved i-Size seats, but can also be
fitted in ISOFIX (ECE R44) type-approved
seats.
NOTE:
The  vehicle  seats,  i-Size  type-approved,  are
marked by the symbol shown in Figure XX. The  following  table,  according  to  European
standard  ECE  129,  indicates  the  possibility
of i-Size child restraint system installation.

Periodic Safety Checks You Should Make 
Outside The Vehicle
Tires 
Examine tires for excessive tread wear and uneven
wear  patterns.  Check  for  stones,  nails,  glass,  or
other  objects  lodged  in  the  tread  or  sidewall.
Inspect the tread for cuts and cracks. Inspect side-
walls for cuts, cracks, and bulges. Check the wheel
nuts for tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights        
Have  someone  observe  the  operation  of  brake
lights  and  exterior  lights  while  you  work  the
controls.  Check  turn  signal  and  high  beam  indi -
cator lights on the instrument panel.
Door Latches 
Check  for  proper  closing,  latching,  and
locking.
Fluid Leaks 
Check  area  under  vehicle  after  overnight
parking  for  fuel,  coolant,  oil,  or  other  fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected, the
cause  should  be  located  and  corrected
immediately.
ALWAYS  REMOVE  THE  EXISTING
FLOOR  MAT  FROM  THE  VEHICLE 
before  installing  any  other  floor  mat.
NEVER  install  or  stack  an  additional
floor mat on top of an existing floor mat.
ONLY  install  floor  mats  designed  to  fit
your  vehicle.  NEVER  install  a  floor  mat
that  cannot  be  properly  attached  and
secured  to  your  vehicle.  If  a  floor  mat
needs  to  be  replaced,  only  use  a  FCA
approved floor mat for the specific make,
model, and year of your vehicle.
ONLY  use  the  driver’s  side  floor  mat  on
the driver’s side floor area. To check for
interference,  with  the  vehicle  properly
parked with the engine off, fully depress
the  accelerator,  the  brake,  and  the
clutch  pedal  (if  present)  to  check  for
interference.  If  your floor  mat  interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
 WARNING! (Continued)
ALWAYS  make  sure  objects  cannot  fall
or  slide  into  the  driver’s  side  floor  area
when the vehicle is moving. Objects can
become  trapped  under  accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
NEVER place any objects under the floor
mat  (e.g.,  towels,  keys,  etc.).  These
objects could change the position of the
floor  mat  and  may  cause  interference
with  the  accelerator,  brake,  or  clutch
pedals.
If  the  vehicle  carpet  has  been  removed
and  re-installed,  always  properly  attach
carpet  to  the  floor  and  check  the  floor
mat  fasteners  are  secure  to  the  vehicle
carpet.  Fully  depress  each  pedal  to
check  for  interference  with  the  acceler -
ator,  brake,  or  clutch  pedals  then
re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning,  always  check  your  floor  mat
has  been  properly  installed  and  is
secured  to  your  vehicle  using  the  floor
mat fasteners by lightly pulling mat.
