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

Operations After Refilling
Proceed as follows:
Fit the cap back on the AdBlue® (UREA)
filler by turning it clockwise and screwing
it completely.
Place the ignition in RUN (it is not neces-
sary to start the engine).
Wait  for  the  indication  on  the  instrument
panel  to  switch  off  before  moving  the  car.
The indication may stay on for a few seconds
to approximately half a minute. If the engine
is  started  and  the  car  is  moved,  the  indica-
tion  will  remain  on  for  longer.  This  will  not
compromise engine operation.
If  the  AdBlue®  (UREA)  was  topped  up
when  the  tank  was  empty,  wait  for
2 minutes before starting the engine.
NOTE:
If  AdBlue®  (UREA)  is  spilled  out  of  the
filler  neck,  clean  up  well  the  area  and
proceed  to  filling  up  again.  If  the  liquid
crystallizes, eliminate it with a sponge and
warm water.
DO NOT EXCEED THE MAXIMUM LEVEL:
this  could  cause  damage  to  the  reservoir.
AdBlue®  (UREA)  freezes  at  under  12°F
(-11°C).  Although  the  system  is  designed
to operate below the  freezing point of  the
AdBlue® (UREA), it is advisable not to fill
the  tank  beyond  the  maximum  level
because  if  the  AdBlue®  (UREA)  freezes
the  system  can  be  damaged.  Follow  the
instructions in this section.
If  the  AdBlue®  (UREA)  is  spilled  on
painted  surfaces  or  aluminum,  immedi -
ately  clean  the  area  with  water  and  use
absorbent material to collect the fluid that
has been spilled on the ground.
Do  not  try  to  start  the  engine  if  AdBlue®
(UREA)  was  accidentally  added  to  the
diesel fuel tank, this can result in serious
engine  damage,  contact  an  authorized
dealer.
Do  not  add  additives  or  other  fluids  to
AdBlue® (UREA), doing so could damage
the system.
The  use  of  non-conforming  or  degraded
AdBlue®  (UREA) may  lead to  indications
appearing on the instrument panel display
refer to “Warning Lights And Messages” in
the  “Getting  To  Know  Your  Instrument
Panel” for further information.
Never pour AdBlue® (UREA) into another
container: it could be contaminated.
If the AdBlue® (UREA) runs out, see refer
to “Warning Lights And Messages”  in  the
“Getting To Know Your Instrument Panel”
for  further  information  to  continue  using
the car normally.

FUSES 
General Information
The  fuses  protect  electrical  systems  against
excessive current.
When  a  device  does  not  work,  you  must
check the fuse element inside the blade fuse
for a break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine  off  may  result  in  vehicle  battery
discharge.
 CAUTION!
Do  not  touch  the  new  bulb  with  your
fingers.  Oil  contamination  will  severely
shorten  bulb  life.  If  the  bulb  comes  in
contact  with  any  oily  surface,  clean  the
bulb with rubbing alcohol.
 WARNING!
When replacing a blown fuse, always use
an  appropriate  replacement  fuse  with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a blown
fuse with metal wires or any other mate-
rial.  Failure  to  use  proper  fuses  may
result in serious personal injury, fire and/
or property damage.
Before  replacing  a  fuse,  make sure  that
the  ignition  is  off  and  that  all  the  other
services  are  switched  off  and/or  disen -
gaged.
If the replaced fuse blows again, contact
an authorized dealer.
If  a  general  protection  fuse  for  safety
systems  (air  bag  system,  braking
system),  power  unit  systems  (engine
system,  gearbox  system)  or  steering
system  blows,  contact  an  authorized
dealer.
