control  systems. SERVICE 
ENGINE 
SOON 
This  system  is  called  OBD II (On-Board 
Diagnostics-Second  Generation)  and  is intended  to 
assure  that  emissions  are  at  acceptable  levels  for the  life 
of  the  vehicle,  helping  to  produce  a  cleaner 
environment.  The

Downloaded from www.Manualslib.com manuals search engine NOTICE: 
If you  keep  driving  your  vehicle  with  this  light 
on,  after  a  while,  your  emission  controls  may  not 
work 
as well,  your  fuel  economy  may  not  be  as 
good  and  your  engine  may  not  run  as  smoothly. 
This  could  lead  to  costly  repairs  that  may  not  be 
covered  by  your  warranty. 
This light  should  come  on, as a  check  to  show  you  it is 
working,  when  the  ignition  is on  and  the engine  is  not 
running. 
If the  light  doesn’t  come  on,  have  it repaired. 
This  light  will  also  come  on  during  a  malfunction  in  one 
of  two  ways: 
0 Light  Flashing -- A  misfire  condition  has  been 
detected.  A  misfire  increases  vehicle  emissions  and 
may  damage  the  emission  control  system  on  your 
vehicle.  Dealer  or  qualified  service  center  diagnosis  and  service  may  be  required. 
Light  On  Steady -- An  emission  control  system 
malfunction  has  been  detected  on  your  vehicle. 
Dealer  or  qualified  service  center  diagnosis  and  service  may  be  required. 
If the  Light Is Flashing 
The  following  may  prevent  more  serious  damage  to 
your  vehicle: 
Reducing  vehicle  speed. 
Avoiding  hard  accelerations. 
Avoiding  steep  uphill  grades. 
0 If  you  are  towing  a  trailer,  reduce  the  amount  of 
cargo  being  hauled 
as soon  as  it is  possible. 
If the  light  stops  flashing  and  remains  on  steady,  see “If 
the  Light 
Is On  Steady’’  following. 
If  the  light  continues  to  flash,  when  it  is  safe  to  do 
so, 
stop  the vehicle. Find  a  safe  place  to  park  your  vehicle. 
Turn  the  key  off,  wait  at  least 
10 seconds  and  restart  the 
engine.  If  the  light  remains 
on steady,  see “If the  Light 
Is  On  Steady’’  following.  If  the light  is  still flashing, 
follow  the  previous  steps,  and  drive  the  vehicle  to  your 
dealer  or  qualified  service  center  for  service.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady Have  you  recentIy  changed  brands of fuel? 
You  may  be  able to  correct  the emission  system 
malfunction  by  considering  the  following: 
Did  you  recently  put  fuel into  your  vehicle? 
If 
so, reinstall  the fuel  cap,  making  sure  to  fully  install 
the  cap.  The diagnostic  system  can  determine  if the  fuel 
cap  has been  left 
off or  improperly  installed. A loose  or 
missing  fuel  cap  will  allow  fuel to  evaporate  into  the 
atmosphere. 
A few  driving  trips  with  the  cap  properly 
installed  should  turn  the light 
off. 
Did  you  just drive  through  a  deep  puddle  of  water? 
If so, your  electrical  system  may  be  wet.  The condition 
will  usually  be  corrected  when  the electrical  system 
dries  out.  A  few  driving  trips  should  turn  the light  off. 
Are  you  low  on  fuel? 
As your engine  starts  to  run  out  of fuel,  your  engine  may 
not  run  as  efficiently  as designed  since  small  amounts  of 
air  are  sucked  into the fuel  line  causing  a  misfire.  The 
system  can  detect  this.  Adding  fuel should  correct  this 
condition.  Make  sure  to  install  the fuel  cap  properly. 
It 
will  take  a  few  driving  trips  to  turn  the light off.  If 
so, be  sure  to  fuel  your  vehicle  with  quality  fuel  (see 
“Fuel”  in  the  Index).  Poor  fuel  quality  will  cause  your \
engine  not  to  run  as efficiently  as  designed.  You  may 
notice  this  as  stalling  after  start-up,  stalling  when  you 
put  the vehicle  into  gear,  misfiring,  hesitation  on 
acceleration  or  stumbling  on  acceleration.  (These 
conditions  may 
go away  once  the  engine  is  warmed  up.) 
This  will  be  detected  by  the  system  and  cause  the  light 
to  turn  on. 
If  you  experience  one  or more  of these  conditions, 
change  the fuel  brand  you  use. 
It will  require  at  least one 
full  tank  of the  proper  fuel to  turn  the  light  off. 
If  none  of the  above  steps  have  made  the  light turn 
off, 
have  your  dealer  or  qualified  service  center  check  the 
vehicle.  Your dealer  has  the proper  test  equipment  and 
diagnostic  tools  to  fix any  mechanical 
or electrical 
problems  that  may  have  developed.

This  light  tells  you if  there 
could  be  a  problem  with 
your  engine  oil  pressure. 
The  light  goes  on  when  you 
turn your  key  to RUN or 
START. It  goes off once  you  start  your  engine.  That’s  a 
check  to  be  sure  the  light  works. 
If it  doesn’t  come  on, 
be  sure 
to have  it fixed so it  will  be  there to warn  you if 
something  goes  wrong. 
When  the  light 
comes on  and stays on,  it means 
that  oil  isn’t  flowing  through  your  engine  properly.  You 
could  be  low 
on oil and you  might  have  some  other 
system  problem. 
/!1 CAUTION: 
Don’t  keep  driving if the oil pressure is low. If 
you  do, your  engine  can  become so hot that it 
catches  fire. You or others  could  be  burned. 
Check your oil as soon as possible  and have  your 
vehicle serviced. 
NOTICE: 
Damage  to  your engine  from  neglected oil 
problems  can  be  costly and 
is not  covered  by 
your  warranty.
