Power Windows 
Use the switches  on the 
driver’s  door armrest  to 
operate  each of the 
windows  while the  ignition 
is  on  or while  Retained 
Accessory  Power  (RAP)  is active.  See “Retained 
Accessory  Power  (RAP)” 
under  Ignition  Positions 
on page 2- 79 for  more 
information.  To 
stop  the window  while  it is lowering,  press the front 
of  the  switch.  To  raise the  window,  press and hold 
the  front  of the switch. 
Window  Lock-Out 
The  driver’s  window  switch  includes a lock-out feature. 
Push 
LOCK OUT  to stop  front  and  rear  passengers 
from using their  window  switches.  The  driver  can 
still control  all the  windows  with  the  lock on.  Push 
LOCK OUT  again to return  to  normal window  operation. 
When  the colored  band  on  the  switch  is showing,  the 
passengers  can  operate their windows. 
In  addition,  each  passenger  door  has  a  window  switch. 
Express-Down  Window 
The driver’s window switch has  an  express-down 
feature. This switch is labeled  AUTO. Tap the rear  of 
the switch,  and  the driver’s window  will open  a 
small  amount. 
If the  rear  of the  switch  is fully  pressed 
and  released, the  window will go all the  way  down. 
Sun Visors 
To  block  out  glare, you  can  swing down  the  visors. 
You  can  also swing  them  from  front 
to side.  The visors 
also  have  extenders  that  you  can  pull out  for  added 
coverage. 
Visor  Vanity  Mirror 
Open  the cover  on the  sun  visor to expose  the  vanity 
mirror.  If the  vehicle  has the optional lighted  vanity 
mirrors, the  lamps  come  on  when  you  open  the  cover.

Mirrors 
Manual  Rearview  Mirror 
To reduce  glare  from  lamps behind you, pull the  lever 
located  in the center  of the  bottom  of the  mirror 
toward you  to  the  night  position. To return the  mirror 
back 
to the  day  position,  push the  lever  away from you.  The mirror also  has an eight-point compass and 
temperature display in the 
upper  right corner on the 
mirror face  and a three-button  Onstar@ system. 
When  the automatic dimming feature  is turned  on, 
the  mirror automatically changes 
to reduce glare from 
headlamps behind  you. A  photocell 
on the  mirror senses 
when  it is  becoming dark  outside. Another photocell 
built into the  mirror face  senses  when headlamps 
are  behind  you.

Automatic  Dimming  Rearview  Mirror 
with  Compass  and  Temperature  Display 
Your  vehicle  may  have  an automatic-dimming  rearview 
mirror  with  a  compass and  temperature  display. 
When turned  on, this  mirror  automatically  dims  to  the 
proper level to  minimize  glare  from  headlamps 
behind you  after  dark. 
The mirror has  an eight-point  compass  and  temperature 
display in the  upper  right  corner  of the mirror  face. 
The display shows  the  current  outside  temperature  and 
the  vehicle's current  direction. 
2-34  

Mirror  Operation 
The  automatic  dimming feature is turned on or  off  by 
briefly  pressing  the COMP  button located on the  bottom 
of the  mirror  face. A light on the mirror will be lit 
while  the  feature  is turned  on.  It will go out while the 
feature  is turned 
off. 
Temperature  Display 
The  TEMP  button located  on the  bottom  of the  mirror 
face  changes  the temperature  display. You can 
select 
OF, "C,  or  turn the display off. 
Compass  Variance 
Press  the  COMP  button  once briefly to turn the 
compass  on or 
off. When  on,  the display will  show the 
compass  direction,  with  a  maximum of two characters. 
For  example, 
NE is  displayed  for north-east. 
Compass  Calibration 
Press  and  hold the COMP button down  for  six seconds 
to  activate  the compass  calibration  mode. 
If your 
vehicle  has  the optional  mirror with the  compass, 
temperature  display  and  OnStar  system,  press the 
on/off  button  for  nine seconds. 
CAL will be displayed in the compass/temperature 
window  on the  mirror. 
The  mirror can be calibrated in one  of two  ways: 
Drive the vehicle ir! circles at 5 mph (8 km/h) 
or less until CAL  is no longer displayed in the 
compass  window. 
0 Drive the vehicle  on your  everyday  routine. 
(This method  may take  longer  to calibrate). 
Compass Variation 
Compass  variance is the difference between earth's 
magnetic north and true geographic north.  If not 
adjusted to  account  for  compass variance, your 
compass could  give false  readings. The  mirror  is set to 
zone  eight upon leaving the factory. 
It will be necessary 
to  adjust the compass  to compensate for  compass 
variance 
if you  live outside  zone  eight. Under certain 
circumstances, such as during  a long distance 
cross-country  trip,  it will be necessary to  adjust for 
compass  variance. 
2-35  

To adjust for compass variance,  do the following: 
1. Find  your  current  location  and variance  zone 
number  on  the map. 
2. Press  and hold  the  COMP  button for  three  seconds. 
If your vehicle  has the optional  mirror  with  the 
compass,  temperature display  and  Onstar@  system, 
press  the on/off  button  for  six  seconds.  Release 
the  button  when 
ZONE is displayed.  The  number 
shown  is the  current  zone  number. 
3. Scroll through the  zone  numbers  that  appear  in the 
compass/temperature  window  on  the  mirror  by 
pressing the  COMP button or  the  on/off  button. 
Once  you  find your  zone  number,  release  the 
button. After about  four  seconds,  the  mirror  will 
return 
to the  compass  and  temperature  display, 
and  the new  zone  number  will be  set. 
2-36  

Outside  Power  Mirrors Outside  Convex  Mirror 
The  power mirror 
control  is located  near 
the driver’s  window, 
on  the armrest. 
Turn  the control counterclockwise  to adjust the 
left  mirror  or  clockwise to  adjust  the right mirror. 
Then  move  the  control in the direction  you  want 
the  mirror  to go.  Your 
passenger’s side  mirror is convex. A convex 
mirror’s surface  is  curved 
so you  can  see more from 
the  driver’s  seat. 
A convex  mirror can make things (like other 
vehicles) 
look farther  away than they  really are. 
If you cut too  sharply into the  right lane, you 
could hit a vehicle on  your  right. Check your 
inside mirror  or glance  over  your  shoulder 
before changing lanes.
