Mist Feature
Push upward on the wiper lever to activate a
single  wipe  to  clear  off  road  mist  or  spray
from a  passing  vehicle.  As  long  as  the  lever
is  held  up,  the  wipers  will  continue  to
operate.
NOTE:
The  mist  feature  does  not  activate  the
washer pump; therefore, no washer fluid will
be  sprayed  on  the  windshield.  The  wash
function must  be  used in  order  to spray  the
windshield with washer fluid.
Rear Window Wiper/Washer — If Equipped  
A  rotary  switch  on  the  center  portion  of  the
windshield  wiper/washer  lever  controls  the
operation of the rear wiper/washer function.Rear Wiper/Washer Control
Rotate the switch  upward to  the first detent
position for intermittent operation and to the
second  detent  for  continuous  rear  wiper
operation. Push  the  wiper  lever  toward  the  instrument
panel to activate the rear washer. The washer
pump  and  wiper  will  continue  to  operate  as
long as the lever is held.
If  the  rear  wiper  is operating  when  the  igni
-
tion is placed in the OFF position, the wiper
will  automatically  return  to the  “park”  posi -
tion. When the vehicle is restarted, the wiper
will  resume  function  at  whichever  position
the switch is set at.
CLIMATE CONTROLS
The  Climate  Control  system  allows  you  to
regulate the temperature, air flow, and direc -
tion of air circulating throughout the vehicle.
The controls are located on the touchscreen
(if  equipped)  and  on  the  instrument  panel
below the radio.

SAFETY FEATURES
Anti-Lock Brake System (ABS) 
The Anti-Lock  Brake System (ABS) provides
increased  vehicle stability  and brake  perfor-
mance  under  most  braking  conditions.  The
system  automatically  prevents  wheel  lock,
and enhances vehicle control during braking.
The  ABS  performs  a  self-check  cycle  to
ensure that the ABS is working properly each
time the vehicle is started and driven. During
this  self-check,  you  may  hear  a  slight
clicking sound as well as some related motor
noises.
ABS  is  activated  during  braking  when  the
system detects  one or more  wheels begin to
lock.  Road  conditions  such  as  ice,  snow,
gravel,  bumps,  railroad  tracks,  loose  debris,
or panic stops may increase the likelihood of
ABS activation(s). You also may experience the following when
ABS activates:
The  ABS  motor  noise  (it  may  continue  to
run for a short time after the stop)
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.
ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modi-
fication  may  result  in  degraded  ABS  perfor -
mance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is placed in the
ON/RUN  mode  and  may  stay  on  for  as  long
as four seconds.
 WARNING!
The  ABS  contains  sophisticated  electronic
equipment  that may  be  susceptible  to  inter -
ference  caused  by  improperly  installed  or
high  output  radio  transmitting  equipment.
This  interference  can  cause  possible  loss  of
anti-lock  braking  capability.  Installation  of
such  equipment  should  be  performed  by
qualified professionals.
Pumping  of  the  Anti-Lock  Brakes  will
diminish  their  effectiveness  and  may
lead  to  a  collision.  Pumping  makes  the
stopping  distance  longer.  Just  press
firmly  on  your  brake  pedal  when  you
need to slow down or stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can  it  increase  braking  or  steering  effi -
ciency  beyond  that  afforded  by  the
condition of the vehicle brakes and tires
or the traction afforded.
The  ABS  cannot  prevent  collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The  capabilities  of  an  ABS  equipped
vehicle  must  never  be  exploited  in  a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.

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

 WARNING!
NEVER  use  a  rearward  facing  child
restraint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERIOUS
INJURY to the CHILD can occur.
It is advisable to always carry children in
a child restraint system on the rear seat,
which  is  the  most  protected  position  in
the event of a collision.
Should it be necessary to carry a child on
the  passenger  side  front  seat  in  a
rear-facing  child  restraint  system,  the
passenger  side  front  air  bag  must  be
deactivated.  Always  make  sure  the
airbag deactivation indicator light is illu -
minated  when  using  a  child  restraint
system. The passenger seat must also be
positioned backward as far as possible to
avoid  the  child  restraint  system  from
coming into contact with the dashboard.
A  deploying  passenger  front air bag  can
cause  death  or  serious  injury  to  a  child
12 years or younger, including a child in
a rear-facing child restraint.
Children  12  years  or  younger  should
always ride buckled up in the rear seat of
a vehicle with a rear seat.
 WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do  not  mount  any  accessories  to  the
knee  impact  bolsters  such  as  alarm
