Turn Signals
Move the multifunction lever up or down and
the  arrows  on  each  side  of  the  instrument
cluster flash to show proper operation of the
front and rear turn signal lights.
NOTE:
If either light remains on and does not flash,
or there is a very fast flash rate, check for a
defective  outside  light  bulb.  If  an  indicator
fails  to  light  when  the  lever  is  moved,  it
would  suggest  that  the  indicator  bulb  is
defective.
Lights-On Reminder
If  the  headlights,  parking  lights,  or  cargo
lights  are  left on after the  ignition is placed
in the OFF position, a chime will sound when
the driver’s door is opened.
Headlight Leveling System — If Equipped 
Your vehicle may be equipped with a headlight
leveling  system.  This  system  allows  the  driver
to  maintain  proper  headlight  beam  position
with the road surface regardless of vehicle load.
The control switch is located on the instrument
panel next to the dimmer control.

WARNING LIGHTS AND 
MESSAGES
The  warning/indicator  lights  will  illuminate
in the instrument panel together with a dedi-
cated  message  and/or  acoustic  signal  when
applicable.  These  indications  are  indicative
and  precautionary  and  as  such  must  not  be
considered  as  exhaustive  and/or  alternative
to  the  information  contained  in  the  Owner’s
Manual, which you are advised to read care -
fully in all cases. Always refer to the informa -
tion  in  this  chapter  in  the  event  of  a failure
indication.  All  active  telltales  will  display
first  if  applicable.  The  system  check  menu
may appear different based upon equipment
options  and  current  vehicle  status.  Some
telltales are optional and may not appear.
Red Warning Lights
 — Air Bag Warning Light 
This warning light will illuminate to indicate
a  fault with  the air  bag, and  will turn  on for
four to  eight  seconds  as  a bulb  check  when
the ignition is placed in the ON/RUN or ACC/
ON/RUN  position.  This  light  will  illuminate
with a single chime when a fault with the air
bag  has  been  detected,  it  will  stay  on  until the fault is cleared. If the light is either  not
on during startup, stays on, or turns on while
driving,  have  the  system  inspected  at  an
authorized dealer as soon as possible.
 — Brake Warning Light 
This  warning  light  monitors  various  brake
functions,  including  brake  fluid  level  and
parking  brake  application.  If the brake  light
turns  on  it  may  indicate  that  the  parking
brake is applied, that the brake fluid level is
low,  or  that  there  is  a  problem  with  the
anti-lock brake system.
If  the  light  remains  on  when  the  parking
brake  has  been  disengaged,  and  the  fluid
level  is  at  the  full  mark  on  the  master
cylinder  reservoir,  it  indicates  a  possible
brake hydraulic system malfunction or that a
problem  with  the  Brake  Booster  has  been
detected  by  the  Anti-Lock  Brake  System
(ABS)  /  Electronic  Stability  Control  (ESC)
system. In this case, the light will remain on
until the condition has been corrected. If the
problem  is  related  to  the  brake  booster,  the
ABS pump will run when applying the brake,
and  a  brake  pedal  pulsation  may  be  felt
during each stop.
The  dual  brake  system  provides  a  reserve
braking capacity in the event of a failure to a
portion  of  the  hydraulic  system.  A  leak  in
either  half  of  the  dual  brake  system is  indi
-
cated by the Brake Warning Light, which will
turn  on  when  the  brake  fluid  level  in  the
master  cylinder  has  dropped  below  a  speci -
fied level.
The  light  will  remain  on  until  the  cause  is
corrected.
NOTE:
The  light  may  flash  momentarily  during
sharp  cornering  maneuvers,  which  change
fluid  level  conditions.  The  vehicle  should
have service  performed,  and the  brake  fluid
level checked.
If  brake  failure  is  indicated,  immediate
repair is necessary.
 WARNING!
Driving  a  vehicle  with  the  red  brake  light
on  is  dangerous.  Part  of  the  brake  system
may have failed. It will take longer to stop
the  vehicle.  You  could  have  a  collision.
Have the vehicle checked immediately.

SAFETY
88
The  BSM  system  notifies  the  driver  of
objects  in  the  detection  zones  by  illumi-
nating the BSM warning light located in the
outside  mirrors  in  addition  to  sounding  an
audible (chime) alert and reducing the radio
volume.  Refer  to  “Modes  Of  Operation”  for
further information.
The  BSM  system  monitors  the  detection
zone from three  different  entry points (side,
rear, front)  while  driving to see if an alert is
necessary.  The  BSM  system  will  issue  an
alert during these types of zone entries.
Entering From The Side
Vehicles  that  move  into  your  adjacent  lanes
from either side of the vehicle.
Entering From The Rear
Vehicles  that  come  up  from  behind  your
vehicle  on  either  side  and  enter  the  rear
detection  zone  with  a  relative  speed  of  less
than 30 mph (48 km/h).
Overtaking Traffic
If you pass another vehicle slowly with a rela -
tive  speed  less than  15 mph  (24 km/h)  and
the  vehicle  remains  in  the  blind  spot  for
approximately 1.5 seconds, the warning light will be illuminated. If the difference in speed
between  the  two  vehicles  is  greater  than
15 mph (24 km/h), the warning light will not
illuminate.
The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts,  walls,  foliage,  berms,  etc.  However,
occasionally  the  system  may  alert  on  such
objects.  This  is  normal  operation  and  your
vehicle does not require service.
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.Rear Cross Path (RCP)
The  Rear  Cross  Path  (RCP)  feature  is
intended to  aid the  driver when backing  out
of  parking  spaces  where  their  vision  of
oncoming vehicles may be blocked. Proceed
slowly  and  cautiously  out  of  the  parking
space  until  the  rear  end  of  the  vehicle  is
exposed.  The  RCP  system  will  then  have  a
clear  view  of  the  cross  traffic  and  if  an
oncoming  vehicle  is  detected,  alert  the
driver.
RCP  monitors  the  rear  detection  zones  on
both sides of the vehicle, for objects that are
moving toward the side of the vehicle with a
minimum  speed  of  approximately  3 mph
(5 km/h),  to  objects  moving  a  maximum  of
approximately 20 mph (32 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on either
side.  If  the  sensors  are  blocked  by  other
structures or vehicles, the system will not be
able to alert the driver.
When  RCP  is  on  and  the  vehicle  is  in
REVERSE  (R),  the  driver  is  alerted  using
both the visual and audible alarms, including
reducing the radio volume.
 WARNING!
The  Blind  Spot  Monitoring  system  is  only
an  aid  to  help  detect  objects  in  the  blind
spot  zones.  The  BSM  system  is  not
designed  to  detect  pedestrians,  bicyclists,
or  animals.  Even  if  your  vehicle  is
equipped  with  the  BSM  system,  always
check  your  vehicle’s  mirrors,  glance  over
your  shoulder,  and  use  your  turn  signal
before changing lanes. Failure to do so can
result in serious injury or death.

Modes Of Operation
Three  selectable  modes  of  operation  are
available  in  the  Uconnect  System.  Refer  to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only
When  operating  in  Blind  Spot  Alert  mode,
the BSM system will provide a visual alert in
the  appropriate  side  view  mirror  based  on  a
detected  object.  However,  when  the  system
is operating in Rear Cross Path (RCP) mode,
the system will respond with both visual andaudible  alerts  when  a  detected  object  is
present.  Whenever  an  audible  alert  is
requested, the radio is muted.
Blind Spot Alert Lights/Chime
When  operating  in  Blind  Spot  Alert  Lights/
Chime mode, the BSM system will provide a
visual  alert  in  the  appropriate  side  view
mirror based on a detected object. If the turn
signal  is  then  activated,  and  it  corresponds
to an alert present on that side of the vehicle,
an  audible  chime  will  also  be  sounded.
Whenever  a  turn  signal  and  detected  object
are  present  on  the  same  side  at  the  same
time,  both  the  visual  and  audible alerts  will
be issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever  an  audible  alert  is  requested  by
the BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond  with  both  visual  and  audible  alerts
when a detected object is present. Whenever
an  audible  alert  is  requested,  the  radio  is
also  muted.  Turn/hazard  signal  status  is
ignored;  the  RCP  state  always  requests  the
chime.Blind Spot Alert Off
When the BSM system is turned off there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current oper
-
ating  mode  when  the  vehicle  is  shut  off.
Each  time  the  vehicle  is  started  the  previ -
ously stored mode will be recalled and used.
Forward Collision Warning (FCW) With 
Mitigation — If Equipped
The Forward Collision Warning (FCW) system
provides the driver with audible, visual warn -
ings (within the instrument  cluster  display),
and may apply a haptic  warning in  the form
of  a  brake  jerk,  to  warn  the  driver  when  it
detects  a  potential  frontal  collision.  The
warnings  are  intended  to  provide  the  driver
with enough time to react, avoid or mitigate
the potential collision.
NOTE:
FCW  monitors  the  information  from  the
forward looking sensors as well as Electronic
Brake  Controller  (EBC),  to  calculate  the
probability  of  a  forward  collision.  When  the
 WARNING!
Rear  Cross  Path  Detection  (RCP)  is  not  a
back  up  aid  system.  It  is  intended  to  be
used  to  help  a  driver  detect  an  oncoming
vehicle  in  a  parking  lot  situation.  Drivers
must  be  careful  when  backing  up,  even
when  using  RCP.  Always  check  carefully
behind  your  vehicle,  look  behind  you,  and
be sure  to check  for  pedestrians, animals,
other  vehicles,  obstructions,  and  blind
spots  before  backing  up.  Failure  to  do  so
can result in serious injury or death.

Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible  and  inflate  the  tires  with  low  pres -
sure (those in a different color in the instru -
ment  cluster  graphic)  to  the  vehicle’s
recommended  cold  placard  pressure  value.
Once  the  system  receives  the  updated  tire
pressures,  the  system  will  automatically
update,  the  pressure  values  in  the  graphic
display  in  the  instrument  cluster  will  return
to their original color, and the TPMS Warning
Light will turn off.  NOTE:
When  filling  warm  tires,  the  tire  pressure
may need to be increased up to an additional
4 psi (28 kPa) above the recommended cold
placard  pressure  in  order  to  turn  the  TPMS
Warning Light off.
The  vehicle  may  need  to  be  driven  for  up  to
10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
Service TPMS Warning
When  a  system  fault  is  detected,  the  TPMS
Warning  Light  will  flash  on  and  off  for  75
seconds  and  then  remain  on  solid.  The
system fault will also sound a chime. In addi
-
tion,  the  instrument  cluster  will  display  a
"SERVICE  TIRE  PRESSURE  SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pres -
sure  value  to  indicate  which  sensor  is  not
being received. If  the  ignition  is  cycled,  this  sequence  will
repeat, providing the system fault still exists.
If  the  system  fault  no  longer  exists,  the
TPMS Warning Light will no longer flash, and
the  “SERVICE  TIRE  PRESSURE  SYSTEM”
message  will  no  longer  display,  and  a  pres
-
sure value will display in place of the dashes.
A  system  fault  can  occur  due  to  any  of  the
following:
Jamming  due  to  electronic  devices  or
driving next to facilities emitting the same
radio frequencies as the TPMS sensors
Installing  some  form  of  aftermarket
window  tinting  that  affects  radio  wave
signals
Lots  of  snow  or  ice  around  the  wheels  or
wheel housings
Using tire chains on the vehicle
Using  wheels/tires  not  equipped  with
TPMS sensors

Enhanced Seat Belt Use Reminder System 
(BeltAlert) 
Front  Seat  and  Second  Row  BeltAlert  (If
Equipped) BeltAlert is a feature intended to remind
the driver and outboard front seat passenger
to  buckle  their  seat  belts.  The  BeltAlert
feature is active whenever the ignition switch
is in the START or ON/RUN position.
Initial Indication
If  the  driver  is  unbuckled  when  the  ignition
switch is first in the START or ON/RUN posi -
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger is
unbuckled when the ignition switch is first in
the START or ON/RUN position, the respec -
tive Seat Belt Reminder Light will turn solid
red  and  remain  red  until  the  seat  belt  is
buckled. The respective Seat Belt Reminder
Light will turn solid green once the seat belt
is  buckled.  After  the  driver  and  outboard
front seat passenger have buckled their seat
belts all Seat Belt Reminder Lights will turn
off.  The  outboard  front  passenger  seat
BeltAlert  is  not  active  when  the  outboard
front passenger seat is unoccupied. BeltAlert Warning Sequence
The BeltAlert warning sequence  is activated
when the vehicle is moving above a specified
vehicle  speed  range  and  the  driver  or
outboard  front  seat  passenger  is  unbuckled
(the outboard front  passenger  seat BeltAlert
is  not  active  when  the  outboard  front
passenger seat is unoccupied). The BeltAlert
warning  sequence  starts  by  blinking  the
respective  Seat  Belt  Reminder  Light  and
sounding  an  intermittent  chime.  Once  the
BeltAlert  warning  sequence  has  completed,
the  Seat  Belt  Reminder  Light  will  remain
solid red until  the  driver  and outboard  front
seat  passenger  are  buckled.  The  BeltAlert
warning  sequence  may  repeat  based  on
vehicle  speed  until  the  driver  and  occupied
outboard front seat passenger seat belts  are
buckled. The driver should instruct all occu
-
pants to buckle their seat belts.
Change of Status
If the driver or outboard front seat passenger
unbuckles their seat belt while the vehicle is
traveling,  the  BeltAlert  warning  sequence
will  begin  until  the  seat  belts  are  buckled
again. The  outboard  front  passenger  seat  BeltAlert
is  not  active  when  the  outboard  front
passenger seat is unoccupied. BeltAlert may
be  triggered  when  an  animal  or  other  items
are  placed  on  the  outboard  front  passenger
seat  or  when  the  seat  is  folded  flat  (if
equipped).  It  is  recommended  that  pets  be
restrained  in  the  rear  seat  (if  equipped)  in
pet harnesses or pet carriers that are secured
by seat belts, and cargo is properly stowed.
Rear Seat BeltAlert (If Equipped)
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled  (if  equipped  with  Rear  Seat
BeltAlert). When the ignition switch is in the
START  or  ON/RUN  position,  a  Seat  Belt
Reminder Light   located in the upper right
corner of the instrument cluster turns on for
each  second  row  seat  position  (if  equipped
with Rear Seat BeltAlert). The Rear BeltAlert
warning  sequence  is  activated  when  the
vehicle  is  moving  above  a  specified  vehicle
speed range.
If a second row seat belt is buckled, the Rear
BeltAlert  Reminder  light  for  that  seating
position will illuminate solid green. If a rear
seat  passenger  is  not  wearing  the  seat  belt,
the  BeltAlert  warning  sequence  will  start  (if
