Dome Lamps 
The dome lamps will come on when  you open  a  door, 
except  with the  liftgate  glass  (if  equipped). 
You can  also turn the dome lamps  on by turning the 
thumbwheel, located next  to the exterior lamp control, 
all the  way  up.  In this position,  the dome lamps will 
remain  on whether  a  door is opened or  closed. 
You can  use  the 
DOME OVERRIDE button, located 
near the  exterior lamp control,  to  set the dome lamps 
to  come on automatically  when  a  door is opened, 
or to  remain 
off. To turn the  lamps off, press the  button 
into the 
in position,  the dome lamps will  remain off 
when a  door  is open.  To return the  lamps to  automatic 
operation, press the  button again and  return it to the 
out  position.  With the  button in this  position, the  dome 
lamps will  come on when  you open  a  door. 
Battery Run-Down Protection 
This feature  shuts off the dome,  courtesy,  vanity, reading 
and glove  box lights 
if they are  left on for more than 
20 minutes  when the ignition  is off. This will keep your 
battery  from running  down. 
If the battery run-down protection  shuts off the  interior 
lamps, it  may be necessary to  do  one  of the following  to 
return to  normal operation: 
Shut off all lamps and close all  doors,  or 
turn the  ignition key to RUN. 
Accessory  Power Outlets 
If your vehicle has this  feature,  you can plug  accessory 
electrical  equipment  into  an accessory  power  outlet. 
Just  pull on the  outlet  cover  to remove  it  and  follow  the 
proper installation  instructions  that are included  with 
any  electrical  equipment  that  you  install. 
The accessory power  outlet is located  on the 
passenger’s  side of the  front  storage  compartment. 
These circuits are  protected  by  a  fuse  and  have 
maximum  current levels. 
Certain power  accessory  plugs  may  not  be  compatible 
to the power  accessory outlet and could  result  in 
blown vehicle or  adapter  fuses. 
If you experience  a 
problem,  see  your  dealer  for additional information  on 
the power accessory  plugs. 
Notice: When  using an accessory  power  outlet, 
maximum  electrical  load  must not  exceed 
25 amps. 
Always  turn 
off any electrical  equipment  when 
not  in use.  Leaving  electrical  equipment  on  for 
extended  periods  will  drain  your  battery. 
Notice: 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  not  covered 
by  your  warran-ly.

Safety Belt  Reminder  Light 
When the key  is turned  to RUN or  START,  a  tone will 
come  on for  several  seconds  to remind  people to fasten 
their safety belts, unless the driver’s safety  belt is 
already buckled. 
The safety belt light will 
also  come  on  and stay on 
for  several seconds, 
then  it will flash  for 
several more. 
If  the driver’s belt  is already buckled, neither the tone 
nor  the  light will  come 
on. 
Air Bag  Readiness  Light 
There is an  air bag  readiness  light on  the  instrument 
panel,  which  shows  AIR  BAG  or the air bag  symbol. 
The  system  checks  the air bag’s electrical  system 
for  malfunctions.  The light tells  you 
if there is  an 
electrical problem.  The  system  check  includes  the 
air  bag  sensor,  the air bag  modules,  the wiring  and 
the  crash sensing and  diagnostic  module.  For more 
information  on the  air  bag  system,  see 
Air Bag System 
on page 1-62.

This  light will 
come  on  when  you  start  your  vehicle,  and 
it will flash  for a few  seconds.  Then  the  light  should 
go  out.  This  means  the system  is ready. 
3-26  

If the air bag  readiness light stays  on after  you start  the 
vehicle  or  comes  on  when 
you are driving, your air 
bag  system  may  not work  properly.  Have your vehicle 
s iced right away. 
Charging System 
If  the  air  bag  readiness light stays  on  after  you 
start  your  vehicle, 
it means  the  air  bag  system 
may  not  be  working  properly.  The  air bags  in 
your  vehicle  may  not  inflate 
in a  crash,  or  they 
could  even  inflate  without  a  crash.  To  help  avoid 
injury  to yourself  or  others,  have  your  vehicle 
serviced  right  away if  the  air  bag  readiness  light 
stays  on  after  you  start  your  vehicle. 
The  air  bag  readiness light should flash  for  a  few 
seconds  when  you  turn the ignition key to 
RUN. 
If  the  light doesn’t  come  on then,  have it fixed so 
it will  be  ready  to  warn  you if there is  a problem. 
Light 
This  light should  come on 
briefly when you turn  on 
the  ignition, before starting  the  engine,  as a  check 
to  show  you  it  is working. 
After  the engine starts,  the light should go  out. 
if it stays 
on  or  comes  on  while you are driving,  you may  have 
a  problem  with your charging system.  It could indicate  a 
problem  with the generator drive  belt, or some  other 
charging  system problem.  Have it checked  right away. 
Driving while this  light  is on  could drain your battery. 
If you  must  drive  a short  distance with this  light 
on, 
it helps  to turn off all  your accessories,  such as 
the  radio and air conditioner.

BRAKE 
This light should come  on 
briefly  when  you  turn 
the ignition key  to 
RUN. 
If it doesn’t  come  on  then, 
have  it fixed 
so it will 
be  ready to  warn  you 
if there’s a problem. 
If  the  light comes  on  while  you are driving, pull 
off the 
road  and  stop  carefully.  You  may  notice that the  pedal 
is  harder  to push.  Or, the  pedal  may 
go closer  to the 
floor. It  may take  longer  to stop.  If the light  is still 
on,  have  the  vehicle towed  for  service. See

You- -)rake  system  may  not be working 
properly 
if the  brake  system warning light  is 
on.  Driving  with  the  brake system  warning light 
on can  lead  to  an  accident. If the  light is still 
on after  you’ve  pulled off the  road and stopped 
carefully,  have the vehicle  towed  for  service. 
Anti-Lock Brake System 
Warning  light 
With the anti-lock brake 
system,  this light will  come 
on  when  you start your 
engine  and may  stay on 
for  several seconds. 
That’s  normal. 
If  the  light stays  on,  or  comes  on  when  you’re driving, 
your vehicle  needs service.  If the  regular brake 
system  warning light  isn’t on, you  still have  brakes, 
but  you  don’t  have  anti-lock brakes.  If the  regular 
brake  system  warning light  is also  on, you  don’t  have 
anti-lock brakes  and there’s  a  problem  with your  regular 
brakes.  See  “Brake  System  Warning  Light” earlier in 
this section. 
The  anti-lock brake  system warning light should  come 
on  briefly  when  you  turn the  ignition  key  to

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. 
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. 
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.  See 
Filling Your Tank  on  page 5-8. 
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 
Gasoline  Octane on  page 5-5. 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.

According to the American  Medical Association,  a 180  Ib 
(82  kg) person  who drinks three  12 ounce 
(355 ml) 
bottles  of beer 
in an  hour  will end  up with  a  BAC 
of  about 
0.06 percent.  The person  would reach the 
same  BAC  by drinking three 
4 ounce  (120 ml) glasses 
of  wine  or three  mixed drinks 
if each  had  1-1/2 ounces 
(45 ml) of a liquor like whiskey, gin  or vodka. 
I 
It’s the  amount  of alcohol  that  counts.  For  example, 
if the same  person  drank three double  martinis 
(3 ounces  or 90 ml of liquor  each) within an hour, 
the  person’s  BAC  would  be  close to 0.12  percent. 
A  person  who  consumes  food just  before  or during 
drinking will  have  a  somewhat  lower  BAC  level. 
There  is a  gender  difference,  too.  Women  generally 
have  a  lower relative  percentage of body  water 
than  men.  Since alcohol is carried  in body  water,  this 
means  that a  woman  generally  will  reach  a  higher  BAC 
level than  a  man of her  same  body  weight  when 
each  has the same  number 
of drinks. 
The  law  in an  increasing  number of  U.S. states,  and 
throughout  Canada,  sets  the  legal limit at  0.08  percent. 
In  some  other countries, the limit  is even  lower. 
For 
example,  it is 0.05 percent in both  France  and  Germany. 
The  BAC  limit for all commercial  drivers in the  United 
States  is 
0.04 percent. 
The  BAC  will be over 
0.10 percent  after  three  to 
six drinks (in  one hour).  Of course,  as  we’ve  seen, 
it  depends  on  how  much  alcohol is  in the  drinks, 
and  how  quickly  the person drinks  them.

Power  Steering Fluid 
When to Check  Power  Steering Fluid 
It is  not  necessary  to  regularly  check  power  steering fluid 
unless  you suspect there  is a leak  in  the  system  or 
you  hear  an  unusual noise.  A fluid  loss  in  this system 
could  indicate a problem.  Have the system  inspected 
and  repaired.  See 
Engine  Compartment  Overview 
on page 
5-14 for  reservoir location. 
How  to  Check  Power  Steering  Fluid 
Turn the key off, let the engine  compartment cool down, 
wipe  the cap  and the  top of the  reservoir  clean, then 
unscrew  the cap  and  wipe  the  dipstick  with  a clean rag. 
Replace  the cap  and  completely  tighten 
it. Then  remove 
the  cap  again  and 
look at the fluid level  on the dipstick. 
The  level should  be  at the 
FULL COLD mark.  If 
necessary,  add only  enough  fluid to  bring  the level  up to 
the  mark. 
What  to  Use 
To determine  what kind of fluid to  use,  see Part D: 
Recommended  Fluids  and Lubricants on page 6-32. 
Always  use  the proper  fluid. Failure to  use  the proper 
fluid  can  cause  leaks and  damage  hoses  and  seals.
