Power Inverter — If Equipped 
There is a 230 Volt, 150 Watt inverter outlet
located on the back of the center console to
convert DC current to AC current.
This outlet can  power  cellular  phones, elec-
tronics and other low power devices requiring
power  up  to  150  Watts.  Certain  high-end
video game consoles exceed this power limit,
as will most power tools.
Power Inverter
The  power  inverter  is  designed  with  built-in
overload  protection.  If  the  power  rating  of
150  Watts  is  exceeded,  the  power  inverter
automatically  shuts  down.  Once  the  elec -
trical  device  has  been  removed  from  the
outlet,  the  inverter  should  automatically
 WARNING!
To avoid serious injury or death:
Do  not  insert  any  objects  into  the
receptacles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause
an electric shock and failure.
 CAUTION!
Do  not  exceed  the  maximum  power  of
160 Watts (13 Amps) at 12 Volts. If the
160  Watt  (13  Amp)  power  rating  is
exceeded the fuse protecting the system
will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object
in the power outlets as this will damage
the  outlet  and  blow  the  fuse.  Improper
use  of  the  power  outlet  can  cause
damage not covered by your New Vehicle
Limited Warranty.
 CAUTION!
Many accessories that can be plugged in
draw  power  from  the  vehicle's  battery,
even  when  not  in  use  (i.e.,  cellular
phones,  etc.).  Eventually,  if  plugged  in
long  enough,  the  vehicle's  battery  will
discharge sufficiently to degrade battery
life  and/or  prevent  the  engine  from
starting.
Accessories that draw higher power (i.e.,
coolers,  vacuum  cleaners,  lights,  etc.),
will  degrade  the  battery  even  more
quickly.  Only  use  these  intermittently
and with greater caution.
After the use of  high power  draw acces-
sories, or long periods of the vehicle not
being  started  (with  accessories  still
plugged in), the vehicle must be driven a
sufficient  length  of  time  to  allow  the
alternator  to  recharge  the  vehicle's
battery.
Power outlets are designed for accessory
plugs  only.  Do  not  hang  any  type  of
accessory  or  accessory  bracket  from the
plug.  Improper  use  of  the  power  outlet
can cause damage.

ENVIRONMENTAL PROTECTION 
SYSTEMS — IF EQUIPPED
Gasoline  Particulate  Filter  (GPF)  —  2.0L  T4
Petrol Versions Only
The Gasoline Particulate Filter is a mechan-
ical  filter,  integral  to  the  exhaust  system,
which  physically  traps  carbon  particles present  in  the  exhaust  gases  of  2.0L  T4
petrol engines.
The  particulate  filter  is  needed  to  eliminate
almost  all  carbon  particle  emissions  in
compliance  with  current/future  regulations
and standards.
Since this filter physically traps particulates,
it  must  be  cleaned  (regenerated)  during
normal  driving  operation  to  remove  carbon
particles.  The  regeneration  procedure  is
controlled  automatically  by  the  engine
control unit according to the filter conditions
and car use conditions.
The following may occur during regeneration:
increased  levels  of  noise  vibration  and
harshness  (NVH)  and  reduced  engine
performance.
Dedicated  messages  can  appear  in  the
instrument  cluster display as a result  of  the
condition  of  the  filter.  Refer  to  the  opening
paragraph  of  the  "Warning  Lights  And
Messages" section for further information.
 WARNING!
Cargo  must  be  securely  tied  down  before
driving  your  vehicle.  Improperly  secured
loads  can  fly  off  the  vehicle,  particularly
at  high  speeds,  resulting  in  personal
injury or property damage. Follow the roof
rack cautions when carrying cargo on your
roof rack.
 CAUTION!
To  avoid  damage  to  the  roof  rack  and
vehicle, do not exceed the maximum roof
rack  load  capacity.  Always  distribute
heavy  loads  as  evenly  as  possible  and
secure the load appropriately.
Long loads, which extend over the wind
-
shield,  should  be  secured  to  both  the
front and rear of the vehicle.
Place  a  blanket  or  other  protection
between the  surface  of  the  roof and  the
load.
Travel  at  reduced  speeds  and  turn
corners  carefully  when  carrying  large  or
heavy  loads  on  the  roof  rack.  Wind
forces,  due  to  natural  causes  or  nearby
truck  traffic,  can  add  sudden  upward
loads.  It  is  recommended  to  not  carry
large flat  loads, such  as  wood  panels  or
surfboards, which may result in damage
to the cargo or your vehicle.
Load  should  always  be  secured  to  cross
bars  first,  with  tie  down  loops  used  as
additional securing points if needed. Tie
loops are intended as supplementary tie
down  points only. Do not use ratcheting
mechanisms  with  the  tie  loops.  Check
the straps frequently to be sure that the
load remains securely attached.
 CAUTION! (Continued)

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

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.

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.
