SAFETY TIPS   
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas     The best protection against carbon monoxide
entry  into  the  vehicle  body  is  a  properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be  detected  inside  the  vehicle,  or  when  the
underside or rear of the vehicle is damaged,
have  a  competent  mechanic  inspect  the
complete exhaust system and adjacent body
areas  for  broken,  damaged,  deteriorated,  or
mispositioned  parts.  Open  seams  or  loose
connections  could  permit  exhaust  fumes  to
seep  into  the  passenger  compartment.  In
addition,  inspect  the  exhaust  system  each
time the vehicle is raised for lubrication or oil
change. Replace as required.
 WARNING!
Do  not  leave  children  or  animals  inside
parked  vehicles  in  hot  weather.  Interior
heat build-up may cause serious injury or
death.
It  is  extremely  dangerous  to  ride  in  a
cargo area, inside or outside of a vehicle.
In  a  collision,  people  riding  in  these
areas  are  more  likely  to  be  seriously
injured or killed.
Do not allow people to ride in any area of
your  vehicle  that  is  not  equipped  with
seats and seat belts.
Be  sure  everyone  in  your  vehicle  is  in  a
seat and using a seat belt properly.
 WARNING!
Exhaust  gases  can  injure  or  kill.  They
contain  carbon  monoxide  (CO),  which  is
colorless  and  odorless.  Breathing  it  can
make  you  unconscious  and  can  eventually
poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage or in
confined  areas  any  longer  than  needed  to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift-
gate/rear  doors  open,  make  sure  that  all
windows  are  closed  and  the  climate  control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle
with  the  engine  running,  adjust  your
heating  or  cooling  controls  to  force
outside  air  into  the  vehicle.  Set  the
blower at high speed.

Safety Checks You Should Make Inside 
The Vehicle 
Seat Belts   
Inspect  the  seat  belt  system  periodically,
checking  for  cuts,  frays,  and  loose  parts.
Damaged parts must be replaced immediately. Do
not disassemble or modify the system.
Front seat belt assemblies must be replaced
after  a  collision.  Rear  seat  belt  assemblies
must  be  replaced  after  a  collision  if  they
have been damaged (i.e., bent retractor, torn
webbing,  etc.).  If  there  is  any  question
regarding  seat  belt  or  retractor  condition,
replace the seat belt.
Air Bag Warning Light  
The Air Bag warning light   will turn on for
four to  eight  seconds  as  a bulb  check  when
the ignition switch is first turned to ON/RUN.
If  the  light  is  either  not  on  during  starting,
stays  on, or turns on while driving,  have  the
system inspected at an  authorized dealer as
soon  as  possible.  This  light  will  illuminate
with a single chime when a fault with the Air
Bag Warning Light has been detected, it will
stay on until the fault is removed. If the light
comes on intermittently or remains on while
driving, have an authorized dealer service the
vehicle  immediately.  Refer  to  “Occupant
Restraint  Systems”  in  “Safety”  for  further
information.
Defroster  
Check  operation  by  selecting  the  defrost
mode  and  place  the  blower  control  on  high
speed.  You  should  be  able  to  feel  the  air
directed  against  the  windshield.  See  an
authorized dealer for service if your defroster
is inoperable.
Floor Mat Safety Information
Always  use  floor  mats  designed  to  fit  your
vehicle.  Only  use  a  floor  mat  that  does  not
interfere  with  the  operation  of  the  pedal
assemblies.  Only  use  a  floor  mat  that  is
securely  attached  using  the  floor  mat
fasteners so it cannot slip out of position and
interfere with the pedal assemblies or impair
safe operation of your vehicle in other ways.
 WARNING!
An improperly attached, damaged, folded, or
stacked  floor  mat,  or  damaged  floor  mat
fasteners  may  cause  your  floor  mat  to
interfere  with  the  accelerator,  brake,  or
clutch  pedals  and  cause  a  loss  of  vehicle
control.  To  prevent  SERIOUS  INJURY  or
DEATH:
ALWAYS  securely  attach    your  floor
mat  using  the  floor  mat  fasteners.  DO
NOT  install  your  floor  mat  upside  down
or turn your floor mat over. Lightly pull to
confirm  mat  is  secured  using  the  floor
mat fasteners on a regular basis.

Periodic Safety Checks You Should Make 
Outside The Vehicle
Tires 
Examine tires for excessive tread wear and uneven
wear  patterns.  Check  for  stones,  nails,  glass,  or
other  objects  lodged  in  the  tread  or  sidewall.
Inspect the tread for cuts and cracks. Inspect side-
walls for cuts, cracks, and bulges. Check the wheel
nuts for tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights        
Have  someone  observe  the  operation  of  brake
lights  and  exterior  lights  while  you  work  the
controls.  Check  turn  signal  and  high  beam  indi -
cator lights on the instrument panel.
Door Latches 
Check  for  proper  closing,  latching,  and
locking.
Fluid Leaks 
Check  area  under  vehicle  after  overnight
parking  for  fuel,  coolant,  oil,  or  other  fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected, the
cause  should  be  located  and  corrected
immediately.
ALWAYS  REMOVE  THE  EXISTING
FLOOR  MAT  FROM  THE  VEHICLE 
before  installing  any  other  floor  mat.
NEVER  install  or  stack  an  additional
floor mat on top of an existing floor mat.
ONLY  install  floor  mats  designed  to  fit
your  vehicle.  NEVER  install  a  floor  mat
that  cannot  be  properly  attached  and
secured  to  your  vehicle.  If  a  floor  mat
needs  to  be  replaced,  only  use  a  FCA
approved floor mat for the specific make,
model, and year of your vehicle.
ONLY  use  the  driver’s  side  floor  mat  on
the driver’s side floor area. To check for
interference,  with  the  vehicle  properly
parked with the engine off, fully depress
the  accelerator,  the  brake,  and  the
clutch  pedal  (if  present)  to  check  for
interference.  If  your floor  mat  interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
 WARNING! (Continued)
ALWAYS  make  sure  objects  cannot  fall
or  slide  into  the  driver’s  side  floor  area
when the vehicle is moving. Objects can
become  trapped  under  accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
NEVER place any objects under the floor
mat  (e.g.,  towels,  keys,  etc.).  These
objects could change the position of the
floor  mat  and  may  cause  interference
with  the  accelerator,  brake,  or  clutch
pedals.
If  the  vehicle  carpet  has  been  removed
and  re-installed,  always  properly  attach
carpet  to  the  floor  and  check  the  floor
mat  fasteners  are  secure  to  the  vehicle
carpet.  Fully  depress  each  pedal  to
check  for  interference  with  the  acceler -
ator,  brake,  or  clutch  pedals  then
re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning,  always  check  your  floor  mat
has  been  properly  installed  and  is
secured  to  your  vehicle  using  the  floor
mat fasteners by lightly pulling mat.

ENGINE BREAK-IN 
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive  moderately  during  the  first  300 miles
(500 km).  After  the  initial  60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While  cruising,  brief  full-throttle  accelera-
tion  within  the  limits  of  local  traffic  laws
contributes  to  a  good  break-in.  Wide-open
throttle acceleration in low gear can be detri -
mental and should be avoided.
The engine oil installed in the engine at the
factory  is  a  high-quality  energy  conserving
type lubricant. Oil changes should be consis -
tent  with  anticipated  climate  conditions
under which vehicle operations will occur.
For  the  recommended  viscosity  and  quality
grades,  refer  to  “Fluids  And  Lubricants”  in
“Technical Specifications”. NOTE:
A new engine may consume some oil during
its  first  few  thousand  miles  (kilometers)  of
operation.  This  should  be  considered  a
normal  part  of  the  break-in  and  not  inter
-
preted as a problem.
AUTOMATIC 
TRANSMISSION  
NOTE:
You  must  press  and  hold  the  brake  pedal
while shifting out of PARK. CAUTION!
Never  use  Non-Detergent  Oil  or  Straight
Mineral  Oil  in  the  engine  or  damage  may
result.
 CAUTION!
Shift  into  or  out  of  PARK  or  REVERSE
only  after  the  vehicle  has  come  to  a
complete stop.
Do  not  shift  between  PARK,  REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your  foot  is  firmly  pressing  the  brake
pedal.
 WARNING!
Never use the PARK position as a substi -
tute for  the parking brake. Always  apply
the parking brake fully when exiting the
vehicle  to  guard  against  vehicle  move-
ment and possible injury or damage.
Your  vehicle  could  move  and  injure  you
and others if it is not in PARK. Check by
trying  to  move  the  transmission  gear
selector  out  of  PARK  with  the  brake
pedal released. Make sure the transmis-
sion  is  in  PARK  before  exiting  the
vehicle.
The transmission may not engage PARK
if the vehicle is moving. Always bring the
vehicle  to  a  complete  stop  before
shifting  to  PARK,  and  verify  that  the
transmission  gear  position  indicator
solidly  indicates  PARK  (P)  without
blinking.  Ensure  that  the  vehicle  is
completely stopped, and the PARK posi -
tion is properly indicated, before exiting
the vehicle.

(Continued)
Ignition Park Interlock
This  vehicle  is  equipped  with  an  Ignition
Park  Interlock  which  requires  the  transmis-
sion to be in PARK before the ignition can be
turned  to  the  OFF  mode.  This  helps  the
driver avoid inadvertently leaving the vehicle
without  placing  the  transmission  in  PARK.
This  system  also  locks  the  transmission  in
PARK  whenever  the  ignition  is  in  the  OFF
mode. NOTE:
The  transmission  is  NOT  locked  in  PARK
when the  ignition  is  in the ACC  mode (even
though  the  engine  will  be  off).  Ensure  that
the transmission is in PARK, and the ignition
is 
OFF   (not  in  ACC  mode)  before  exiting  the
vehicle.
Brake/Transmission Shift Interlock 
System 
This vehicle is equipped with a Brake Trans -
mission  Shift  Interlock  system  (BTSI)  that
holds the transmission gear selector in PARK
unless  the  brakes  are  applied.  To  shift  the
transmission  out  of  PARK,  the  engine  must
be  running  and  the  brake  pedal  must  be
pressed.  The  brake  pedal  must  also  be
pressed  to  shift  from  NEUTRAL  into  DRIVE
or  REVERSE when the  vehicle is stopped or
moving at low speeds.
It  is  dangerous  to  shift  out  of  PARK  or
NEUTRAL  if  the  engine  speed  is  higher
than idle speed. If your foot is not firmly
pressing  the  brake  pedal,  the  vehicle
could  accelerate  quickly  forward  or  in
reverse.  You  could  lose  control  of  the
vehicle  and  hit  someone  or  something.
Only  shift  into  gear  when  the  engine  is
idling  normally  and  your  foot  is  firmly
pressing the brake pedal.
Unintended movement of a vehicle could
injure  those  in  or  near  the  vehicle.  As
with all vehicles, you should never exit a
vehicle  while  the  engine  is  running.
Before exiting a vehicle, always come to
a complete stop, then apply the parking
brake, shift the transmission into PARK,
and turn the ignition OFF. When the igni -
tion  is  in  the  OFF  mode,  the  transmis-
sion  is  locked  in  PARK,  securing  the
vehicle against unwanted movement.
When  exiting  the  vehicle,  always  make
sure  the  ignition  is  in  the  OFF  mode,
remove the key fob from the vehicle, and
lock the vehicle.
 WARNING! (Continued)
Never  leave  children  alone  in  a  vehicle,
or  with  access  to  an  unlocked  vehicle.
Allowing children to be in a vehicle unat -
tended  is  dangerous  for  a  number  of
reasons. A child or others could be seri -
ously  or  fatally  injured.  Children  should
be  warned  not  to  touch  the  parking
brake,  brake  pedal  or  the  transmission
gear selector.
Do  not  leave  the  key  fob  in  or  near  the
vehicle  (or  in  a  location  accessible  to
children),  and  do  not  leave  the  ignition
in  the  ACC  or  ON/RUN  mode.  A  child
could  operate  power  windows,  other
controls, or move the vehicle.
