If 
the  Light 
Is 
On 
Steady 
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. 
Have  you  recently  changed  brands 
of 
fuel? 
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  retailer  or  qualified  service  center check the 
vehicle. Your retailer has the proper  test  equipment  and 
diagnostic  tools  to fix any  mechanical  or  electrical 
problems  that  may  have  developed.
