IN CASE OF EMERGENCY 409
ENHANCED ACCIDENT RESPONSE SYSTEM (EARS) 
This  vehicle  is  equipped  with  an  Enhanced  Accident
Response System. Please refer to “Occupant Restraint Systems” in “Safety” for
further  information  on  the  Enhanced  Accident  Response
System (EARS) function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data Recorder (EDR).
The main purpose of an EDR is to record data that will assist
in understanding how a vehicle’s systems performed under
certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle.
Please refer to “Occupant Restraint Systems” in “Safety” for
further information on the Event Data Recorder (EDR).WARNING!
• Do  not  use  a  chain  for  freeing  a  stuck  vehicle.  Chains
may break, causing serious injury or death.
• Stand  clear  of  vehicles  when  pulling  with  tow  hooks.
Tow  straps  may  become  disengaged,  causing  serious
injury.
CAUTION!
Tow  hooks  are  for  emergency  use  only,  to  rescue  a
vehicle  stranded  off road. Do  not use  tow  hooks  for  tow
truck  hookup  or  highway  towing.  You  could  damage
your vehicle.

SERVICING AND MAINTENANCESCHEDULED SERVICING  
Your vehicle is equipped with an automatic oil change indicator
system. The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled maintenance.
Based  on  engine  operation  conditions,  the  oil  change  indi -
cator  message  will  illuminate.  This  means  that  service  is
required  for  your  vehicle.  Operating  conditions  such  as
frequent  short-trips,  trailer  tow,  extremely  hot  or  cold
ambient  temperatures,  and  E85  fuel  usage  will  influence
when  the  “Oil  Change  Required”  message  is  displayed.
Severe  Operating  Conditions  can  cause  the  change  oil
message to illuminate as early as 3,500 miles (5,600 km) since
last  reset.  Have  your  vehicle  serviced  as  soon  as  possible,
within the next 500 miles (805 km).
Your  authorized  dealer  will  reset  the  oil  change  indicator
message  after completing the  scheduled  oil  change. If  a sched -
uled oil change is performed by someone other than your autho -
rized  dealer,  the  message  can be  reset by referring to  the steps
described  under  “Instrument  Cluster  Display”  in  “Getting  To
Know Your Instrument Panel” for further information. Gasoline Engines:
Under  no  circumstances  should  oil  change  intervals  exceed
8,000 miles  (13,000 km),  twelve  months  or  350  hours  of
engine  run  time,  whichever  comes  first.  The  350  hours  of
engine  run  or  idle  time  is  generally  only  a  concern  for  fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time  if  the vehicle is  operated  in  a  dusty  and off
road  environment  or  is  operated  predominately  at  idle  or
very  low  engine  RPM’s.  This  type  of  vehicle  use  is  consid -
ered Severe Duty.

Heavy Duty Use Of The Vehicle
Change  engine  oil  at  4,000 miles  (6,500 km)  or  350  hours  of
engine run time  if  the vehicle is  operated  in  a  dusty  and off
road  environment  or  is  operated  predominately  at  idle  or
only  very  low  engine  RPM’s.  This  type  of  vehicle  use  is
considered Severe Duty.WARNING!
• You can be badly injured working on or around a motor
vehicle.  Do  only  service  work  for  which  you  have  the
knowledge  and  the  right  equipment.  If  you  have  any
doubt  about your ability  to perform  a  service job, take
your vehicle to a competent mechanic.
• Failure  to  properly  inspect  and  maintain  your  vehicle
could  result  in  a  component  malfunction  and  effect
vehicle handling and performance. This could cause an
accident.

Checking Oil Level — Gas Engine 
To  assure  proper  lubrication  of  your  vehicle's  engine,  the
engine oil must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel stop. The best
time to check the engine oil level is about five  minutes after
a fully warmed up engine is shut off.
Checking  the  oil  while  the  vehicle  is  on  level  ground  will
improve the accuracy of the oil level readings. Always main -
tain  the  oil  level  within  the  SAFE  zone  on  the  dipstick.
Adding one quart of oil when the reading is at the bottom of
the SAFE  zone  will result  in  a  reading  at  the  top  of  the  safe
zone on these engines.
Adding Washer Fluid  
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with  windshield  washer  solvent  only  (not  radiator  anti -
freeze). When refilling the washer fluid reservoir, take some washer  fluid  and  apply  it  to  a  cloth  or  towel  and  wipe  the
wiper blades clean. This will help blade performance.
To  prevent  freeze-up  of  your  windshield  washer  system  in
cold  weather,  select  a  solution  or  mixture  that  meets  or
exceeds  the  temperature  range  of  your  climate.  This  rating
information can be found on most washer fluid containers.
After the engine has warmed up, operate the defroster for a
few minutes to reduce the possibility of smearing or freezing
the  fluid  on  the  cold  windshield.  Windshield  washer  solu -
tion  used  with  water  as  directed  on  the  container,  aids
cleaning action, reduces the freezing point to avoid line clog -
ging, and is not harmful to paint or trim.CAUTION!
Overfilling or underfilling will cause oil aeration or loss
of oil pressure. This could damage your engine. WARNING!
Commercially  available  windshield  washer  solvents  are
flammable.  They  could  ignite  and  burn  you.  Care  must
be  exercised when filling or  working around the  washer
solution.

Maintenance-Free Battery 
Your  vehicle  is  equipped  with  a  maintenance-free  battery.
You  will  never  have  to  add  water,  nor  is  periodic  mainte -
nance required.
DEALER SERVICE 
An  authorized  dealer  has  the  qualified  service  personnel,
special  tools,  and  equipment  to  perform  all  service  opera -
tions  in  an  expert  manner.  Service  Manuals  are  available
which include detailed service information for your vehicle.
Refer to these Service Manuals before attempting any proce -
dure yourself.
NOTE:
Intentional  tampering  with  emissions  control  systems  may
void your warranty and could result in civil penalties being
assessed against you.WARNING!
• Battery  fluid  is  a  corrosive  acid  solution  and  can  burn
or even blind you. Do not allow battery fluid to contact
your eyes,  skin, or clothing. Do not lean  over a battery
when  attaching  clamps.  If  acid  splashes  in  eyes  or  on
skin, flush the area immediately with large amounts of
water.  Refer  to  “Jump  Starting Procedure” in “In  Case
Of Emergency” for further information.
• Battery gas is flammable and explosive. Keep flame or
sparks  away  from  the  battery.  Do  not  use  a  booster
battery  or  any  other  booster  source  with  an  output
greater  than  12  Volts.  Do  not  allow  cable  clamps  to
touch each other.
• Battery posts, terminals, and related accessories contain
lead and lead compounds. Wash hands after handling. CAUTION!
• It is essential  when replacing the cables on the battery
that  the  positive  cable  is  attached  to  the  positive  post
and the negative cable is attached to the negative post.
Battery  posts  are  marked  positive  (+)  and  negative  (-)
and  are  identified  on  the  battery  case.  Cable  clamps
should be tight on the terminal posts and free of corro -
sion.
• If  a  “fast  charger”  is  used  while  the  battery  is  in  the
vehicle,  disconnect  both  vehicle  battery  cables  before
connecting the charger to the battery. Do not use a “fast
charger” to provide starting voltage.
