Gear Shift Indicator (GSI) — If Equipped
The  Gear  Shift  Indicator  (GSI)  system  is
enabled  on  vehicles  when  automatic  trans-
mission  is  in  manual  shift  mode.  The  GSI
provides  the  driver  with  a  visual  indication
when the recommended gear shift point has
been  reached.  This  indication  notifies  the
driver that changing gears will allow a reduc -
tion in fuel consumption. When the up shift
indicator is shown on the instrument cluster
display,  the  GSI  is  advising  the  driver  to
engage  a  higher  gear.  When  the  down  shift
indicator is shown on the display, the GSI is
advising the driver to engage a lower gear.
The GSI remains illuminated until the driver
changes  gear,  or  the  driving  conditions
return to a situation where changing gears is
not required to improve fuel consumption.
Diesel Displays
When  the  appropriate  conditions  exist,  the
following messages display in the instrument
cluster display:

Diesel Particulate Filter (DPF) Messages 
This engine meets all required diesel engine
emissions standards. To achieve these emis -
sions  standards,  your  vehicle  is  equipped
with  a  state-of-the-art  engine  and  exhaust
system.  These  systems  are  seamlessly  inte -
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages  engine  combustion  to  allow  the
exhaust  system’s  catalyst  to  trap  and  burn
Particulate  Matter  (PM)  pollutants,  with  no
input or interaction on your part.
 WARNING!
A hot exhaust system can start a fire if you
park  over  materials  that  can  burn.  Such
materials  might  be  grass  or  leaves  coming
into  contact  with  your  exhaust  system.  Do
not  park  or  operate  your  vehicle  in  areas
where  your  exhaust  system  can  contact
anything that can burn.
 CAUTION!
Always drive  at  a  speed appropriate  to the
traffic  conditions,  the  weather  and  traffic
regulations.  The  engine  may  be  switched
off even if the warning light is on: repeated
interruptions  of  the  regeneration  process
could  cause  an  early  deterioration  of
engine  oil.  For  this  reason  it  is  always
advisable  to  wait  for  the  symbol  to  go  off
before turning off the engine, following the
instructions  above.  Do  not  complete  the
DPF regeneration process when the vehicle
is stopped.

Refer  to  “Starting  The  Engine”  in  “Starting
And Operating” for further information.
NOTE:
The  “Wait  To  Start”  telltale  may  not  illumi-
nate  if  the  intake  manifold  temperature  is
warm enough.
 — Low Diesel Exhaust Emissions Additive 
AdBlue® Indicator Light — If Equipped
The  Low  Diesel  Exhaust  Emissions  Additive
AdBlue®  indicator  light  illuminates  when
the AdBlue® (UREA) level is low.
Fill  the  AdBlue®  tank  as  soon  as  possible
with  at  least  1.3  gallons  (5  liters)  of
AdBlue®.
If  filling  the  tank  is  done  with  a  remaining
range of AdBlue® in the tank equal to zero,
you  may  need  to  wait  two  minutes  before
starting the vehicle.
Refer to “Adding AdBlue®” in “Starting And
Operating” for further information.
 — Water In Fuel Indicator Light — If 
Equipped
The “Water In Fuel Indicator Light” will illu -
minate  when  there  is  water  detected  in  the
fuel  filter.  If  this  light  remains  on,  DO  NOT start  the  vehicle  before  you  drain  the  water
from  the  fuel  filter  to  prevent  engine
damage,  and  please  see  an  authorized
dealer.
Green Indicator Lights
 — Adaptive Cruise Control (ACC) Set With 
No Target Detected Indicator Light — If 
Equipped
This  light  will  turn  on  when  the  Adaptive
Cruise  Control  is  set  and  there  is  no  target
vehicle  detected.  Refer  to  “Adaptive  Cruise
Control  (ACC)  —  If  Equipped”  in  “Starting
And Operating” for further information.
 — Adaptive Cruise Control (ACC) Set With 
Target Light — If Equipped
This  will  display  when  the  ACC  is  set  and  a
target vehicle is detected. Refer to “Adaptive
Cruise  Control  (ACC)  —  If  Equipped”  in
“Starting And Operating” for further informa -
tion.
 — 4WD Auto Indicator Light — If 
Equipped
This light alerts the driver that the vehicle is
in  the  four-wheel  drive  auto  mode.  The
system  will  provide  power  to all  four  wheels
and  shift  the  power  between  the  front  and
rear  axles  as  needed.  This  will  provide
maximum traction in dry and slippery condi -
tions.
 — Active Speed Limiter SET Indicator 
Light — If Equipped With A Premium 
Instrument Cluster
This indicator  light will illuminate when  the
Active  Speed  Limiter  is  on  and  set  to  a
specific speed.
Refer  to  “Active  Speed  Limiter  —  If
Equipped”  in  “Starting  And  Operating”  for
further information.
 CAUTION!
The  presence  of  water  in  the  fuel  system
circuit  may  cause  severe  damage  to  the
injection  system  and  irregular  engine
operation.  If  the  indicator  light  is
illuminated,  contact  an  authorized  dealer
as soon as possible to bleed the system. If
the  above  indications  come  on
immediately  after  refuelling,  water  has
probably been poured into the tank: switch
the engine off immediately and contact an
authorized dealer.

As the air bags deflate, you may see some
smoke-like  particles.  The  particles  are  a
normal  by-product  of  the  process  that
generates  the  non-toxic  gas  used  for  air
bag inflation. These airborne particles may
irritate  the  skin,  eyes,  nose,  or  throat.  If
you  have  skin  or  eye  irritation,  rinse  the
area with cool water. For nose or throat irri-
tation,  move  to  fresh  air.  If  the  irritation
continues, see your  doctor. If these parti -
cles  settle  on  your  clothing,  follow  the
garment  manufacturer’s  instructions  for
cleaning.
Do  not  drive  your  vehicle  after  the  air  bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you. NOTE:
Air  bag  covers  may  not  be  obvious  in  the
interior trim, but they will open during air
bag deployment.
After  any  collision,  the  vehicle  should  be
taken to an authorized dealer immediately.
Enhanced Accident Response System 
In the event of an impact, if the communica
-
tion  network  remains  intact,  and  the  power
remains  intact,  depending  on  the  nature  of
the event, the Occupant Restraint Controller
(ORC)  will  determine  whether  to  have  the
Enhanced  Accident  Response  System
perform the following functions:
Cut off fuel to the engine (If Equipped)
Cut off battery power to the electric motor
(If Equipped)
Flash  hazard  lights as  long as  the  battery
has power
Turn  on  the  interior  lights,  which  remain
on as long as the battery has power or for
15 minutes  from  the  intervention  of  the
Enhanced Accident Response System.
Unlock the power door locks. Your vehicle may also be designed to perform
any  of  these  other  functions  in  response  to
the Enhanced Accident Response System:
Turn  off  the  Fuel  Filter  Heater,  Turn  off
the  HVAC  Blower  Motor,  Close  the  HVAC
Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
 WARNING!
Deployed  air  bags  and  seat  belt
pretensioners  cannot  protect  you  in
another  collision.  Have  the  air  bags,  seat
belt  pretensioners,  and  the  seat  belt
retractor  assemblies  replaced  by  an
authorized  dealer  immediately.  Also,  have
the  Occupant  Restraint  Controller  System
serviced as well.
