EXTERIOR LIGHTS  
Headlight Switch
The  headlight  switch is  located  on  the  right
side  of  the  instrument  panel.  This  switch
controls  the  operation  of  the  headlights,
parking  lights,  automatic  headlights  (if
equipped),  instrument  panel  lights,  instru-
ment  panel  light  operation,  interior  lights,
fog  lights  (if  equipped),  and  headlight
leveling (if equipped). Headlight Switch
Rotate the headlight switch clockwise to the
first detent for parking light  and  instrument
panel  light  operation.  Rotate  the  headlight
switch  to  the  second  detent  for  headlight,
parking  light,  and  instrument  panel  light
operation.
Daytime Running Lights — If Equipped 
The Daytime Running Lights (DRLs) are in a
dedicated  position  below  the  headlight
assembly.  DRLs  are  active  when  the  Low Beams  are  not  and  when  the  vehicle  is
shifted into any position other than PARK.
NOTE:
The  Daytime  Running  Lights,  on  the  same
side of the vehicle as the active turn  signal,
will turn off automatically when a turn signal
is  in  operation  and  turn  on  again  when  the
turn signal is not operating.
High/Low Beam Switch  
Push  the  multifunction  lever  toward  the
instrument panel to switch the headlights to
high  beams.  The  lever  will  return  to  the
centered position. To return the headlights to
low beam, pull the lever toward the steering
wheel,  or  push  the  lever  toward  the  instru
-
ment panel.
Multifunction Lever
 WARNING!
Persons  who  are  unable  to  feel  pain  to
the  skin  because  of  advanced  age,
chronic  illness,  diabetes,  spinal  cord
injury,  medication, alcohol  use, exhaus-
tion,  or  other  physical  conditions  must
exercise  care  when  using  the  steering
wheel heater. It may cause burns even at
low  temperatures,  especially  if  used  for
long periods.
Do  not  place  anything  on  the  steering
wheel  that  insulates  against  heat,  such
as  a  blanket  or  steering  wheel  covers  of
any  type  and  material.  This  may  cause
the steering wheel heater to overheat.1 — Instrument Panel Dimmer Control

Automatic High Beam — 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 vehicle’s header. 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  High  Beam”  within  your
Uconnect  settings,  as  well  as  turning  the
headlight  switch  to  the  AUTO  position  and
placing  the  multifunction  lever  in  the  high
beam position. Refer to “Uconnect Settings”
in  “Multimedia”  in  the  Owner’s  Manual  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  wind-
shield  or  camera  lens  will  cause  the
system to function improperly.
Flash-To-Pass  
You  can  signal  another  vehicle  with  your
headlights  by  lightly  pulling  the  multifunc -
tion  lever  toward  you.  This  will  cause  the
high beam headlights to turn on, and remain
on, until the lever is released.
Automatic Headlights — If Equipped 
This  system  automatically  turns  the  head -
lights  on  or  off  according  to  ambient  light
levels.  To  turn  the  system  on,  rotate  the
headlight switch clockwise to the last detent
for automatic headlight operation. When the
system  is  on,  the  headlight  time  delay
feature is also on. This means the headlights
will  stay  on  for  up  to  90  seconds  after  you
place  the  ignition  into  the  OFF  position.  To
turn  the  automatic  system  off,  move  the
headlight switch out of the AUTO position.
NOTE:
The engine must be running before the head -
lights will come on in the automatic mode.
Front And Rear Fog Lights — If Equipped  
The fog light switches are built into the head -
light switch. Fog Light Switch Location
To  activate  the  front  fog  lights,  push  the
upper  half  of  the  headlight  switch.  To  turn
off  the  front  fog  lights,  push  the  upper  half
of the headlight switch a second time.
To activate the rear fog lights, push the lower
half  of  the  headlight  switch.  To  turn  off  the
rear  fog  lights,  push  the  lower  half  of  the
headlight switch a second time.
NOTE:
To turn on the rear fog lamps, the low beam
lamps or front fog lamps must first be active.
An  indicator  light  in  the  instrument  cluster
illuminates when the fog lights are turned on.

SERVICING AND MAINTENANCE
242
If you are storing your vehicle for more than
21  days,  we  recommend  that  you  take  the
following steps to minimize the drain on your
vehicle's battery:
Disconnect  the  negative  cable  from
battery.
If your vehicle is equipped with Stop/Start
system then disconnect both the main and
supplemental negative battery cables.
Any time you store your vehicle or keep it
out of service (i.e., vacation) for two weeks
or more, run the air conditioning system at
idle for about five minutes in the fresh air
and  high  blower  setting.  This  will  ensure
adequate  system  lubrication  to  minimize
the  possibility  of  compressor  damage
when the system is started again.
If  assistance  is  needed  to  disconnect  the
battery system, see your authorized dealer.Battery Cable Disconnect
NOTE:
You must isolate the supplemental battery
connection  point,  as  well  as  the  main
battery terminal from the post, as shown in
the  image,  to  fully  de-energize  both
batteries  for  storage.  If  assistance  is
needed  to  disconnect  the  battery  system,
see an authorized dealer.
Do  not  disconnect  the  Intelligent  Battery
Sensor  (IBS),  or  your  Stop/Start  system
may  not  function  for  up  to  24  hours,  due
to the IBS being set into learn mode.
BODYWORK
Body And Underbody Maintenance
Cleaning Headlights 
Your  vehicle  is  equipped  with  plastic  head -
lights and fog lights that are lighter and less
susceptible  to  stone  breakage  than  glass
headlights.
Plastic  is  not  as  scratch  resistant  as  glass
and  therefore  different  lens  cleaning  proce -
dures must be followed.
To minimize the possibility of scratching the
lenses  and  reducing  light  output,  avoid
wiping with a dry cloth. To remove road dirt,
wash  with  a  mild  soap  solution  followed  by
rinsing.
Do  not  use  abrasive  cleaning  components,
solvents, steel wool or other aggressive mate -
rial to clean the lenses.
 CAUTION!
If  the  negative  battery  cables  are  not
isolated  properly  it  can  cause  a  potential
power  spike  or  surge  in  the  system,
resulting  in  damage  to  essential  electrical
components.

2 — Main Negative Battery Cable
