You can use the DOME OVERRIDE button, located Mirrors 
below the parking/headlamp knob, to set the  dome 
lamps  to come 
on automatically  when the doors  are Electrochromic  Daymight Inside Rearview 
opened, or to remain  off. To turn the  lamps  off, press the Mirror 
button  once into the “in” position.  With the button  in 
this position, the  dome lamps  will remain  off when the 
doors  are 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  the door. This  will 
not  override  the illuminated entry  feature. 
Battery Run-Down  Protection 
This feature shuts off the dome,  courtesy,  vanity, 
reading,  glove 
box and underhood  lamps 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: 
0 Shut  off  all  lamps and  close all doors,  or 
Turn the ignition  key to RUN. 
This  mirror automatically  changes to reduce glare from 
headlamps  behind you. A photocell  on 
the back of the 
mirror  senses when it is  becoming dark  outside. Another 
photocell 
built into  the mirror  surface  senses when 
headlamps  are behind you. 
At night,  when the glare  is too  high, the mirror  will 
gradually darken 
to reduce  glare  (this change may take a 
few  seconds).  The  mirror will return  to its  clear  daytime 
state  when  the glare 
is reduced.  The vehicle will  also 
return to its  clear daytime  state when  the vehicle is  put 
into 
REVERSE (R).

Press  the OFF AUTO  button  at  the  base of the  mirror  to 
turn  on the  automatic  feature.  The button  has 
an 
indicator  light  to  show it is  on.  Press  the OFF AUTO 
button  to  turn  the  automatic  feature 
off. 
Time  Delay 
The  automatic  mirror  has  a time  delay  feature  which 
prevents  unnecessary  switching  from  the  night  back  to 
the  day  position.  This  delay  prevents  rapid  changing  of 
the  mirror  as  you  drive  under  lights  and  through  traffic. 
Cleaning  the  Photocells 
Use  a cotton  swab  and  glass  cleaner  to  clean  the 
photocells  when  necessary.  The 
control  is  located  on  the 
driver’s  door  armrest. 
Move  the  upper  control  to  the  left  or  right  to  choose  the  mirror,  then  press  the 
arrows on  the  control  pad  to  adjust 
the  mirror.

Convex Outside  Mirror 
Your passenger’s side mirror is convex. A convex 
mirror’s  surface 
is curved so you can  see more from the 
driver’s seat. 
Storage Compartments 
Glove Box 
To open your  glove box, lift the lever on the front of the 
glove  box and lower the door. 
The glove box should not 
1 be open while driving. 
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. 
4 Overhead Console 
Heated  Outside  Rearview  Mirror 
When you operate the rear  window defogger,  a defogger 
also  warms the heated driver’s  and passenger’s  outside 
rearview  mirrors 
to help  clear  them  of ice and snow. 
See  “Rear  Window Defogger” in the Index  for 
more information.  The 
overhead console includes reading  lamps,  a driver 
information  system, 
a storage compartment  for 
sunglasses and  a universal transmitter.

Reading La ~  ~ ps 
Press the button near  each 
lamp  to  turn the  reading 
lamps 
on and off. 
The  lamps  can  also  be  swiveled 
to point  in the 
desired  direction. 
Driver  Information System 
This  system  displays  the outside  air  temperature, 
compass  direction  and trip information  in the 
overhead  console. 
USMET The USMET  (United Statedmetric)  button 
allows  you to switch the display  between 
the English 
and  metric  system. 
MODE: The  MODE  button can be used to  toggle 
between  three  modes 
of operation: OFF, COMP/TEMP 
and  TRIP. 
OFF: This  button turns the system off. 
COMP/TEMP: The display provides  the  outside 
temperature  and  one 
of eight  compass  readings to 
indicate  the direction  the vehicle  is facing. 
Before  you turn  on the ignition  and move 
the vehicle, 
the  temperature  indicated  will  be the last  outside 
temperature  recorded with the ignition  on. If the  outside 
temperature  is 
37°F (3°C) or lower, the display  will 
toggle between  the word  ICE and the  current 
temperature  every  eight  seconds.  This  is a warning 
to 
the driver that road conditions may be icy, and that 
appropriate  precautions  should be taken. 
The  compass  is  self-calibrating, 
so it does  not  need  to  be 
manually  set.  However,  if C  (Calibration)  is  displayed,  the 
compass  will  need 
to be  calibrated.  You  may also  place  the 
compass  in  a noncalibrated  mode  by  pressing  and  holding 
the  MODE  and USMET  buttons  simultaneously  while  in 
the  COMPREMP  mode.  After  about  10  seconds,  the 
compass  will  display 
C and you  can  release  the  buttons. 
Drive 
the vehicle in a  complete 360" circle  three  times  at 
a speed  of less  than 5 mph (8 km/h), and  the  compass  will 
function  normally.  Once  the  calibration  is  complete,  the 
display  will  return 
to a  compass  reading.

Variance is the difference between magnetic north and 
geographic north.  In some  areas,  the difference between 
the two can be great enough to  cause  false  compass 
readings.  If this happens, follow these instructions to set 
the variance for your particular location: 
1. Find your location on the zone  map  earlier in this 
section.  Note your zone number. 
2. Press and  hold  both the MODE  and the USMET 
buttons 
in the  COMP/TEMP  mode. 
3. After five  seconds,  the compass will acknowledge 
the  variation mode  by displaying  the current zone 
number, 
When it  does,  release both buttons. 
4. Press US/MET  until your zone number appears on 
the display. 
5. Press  MODE  to enter your zone  number. Your 
variance  is  now set and  the display will return to the 
COMP/TEMP  mode.

button  will step 
you through the following 
TRIP functions: 
0 AVG ECON: The  average  fuel economy  since the

distance that can  be travelled  with  the remaining fuel 
in the tank, based  on the fuel economy  for the last 
few hours 
of driving. 
FUEL USED: The  fuel  used since the last reset 
is displayed. 
AVG SPEED: The  average  speed since the last reset 
is  displayed.

thrown  about  the  vehicle  during  a collision or 
sudden  maneuver.  You or others  could  be 
injured. 
If you  remove  the  cover,  always store it 
outside of the  vehicle.  When  you  put  it back, 
always  be  sure  that  it is  securely  reattached.  Cargo  Tie  Downs

If you try to carry  something on  top of your 
vehicle  that 
is longer or wider than  the  luggage 
carrier 
-- like paneling,  plywood, a mattress,  and 
so forth -- the  wind  can catch  it  as you  drive 
along.  This can cause  you to lose  control.  What 
you  are  carrying 
could be  violently  torn off, and 
this  could  cause  you or other  drivers 
to have a 
collision,  and of course  damage  your vehicle. You 
may  be  able to carry something like this inside. 
But, never  carry something longer  or wider  than 
the  luggage  carrier on top 
of your  vehicle. 
Use GM accessory racks  that are compatible  with your 
luggage  carrier  for  transporting sports  equipment.  These 
are available  through  your 
GM dealer. 
You can adjust the  crossrails  to  handle  loads of various 
sizes. Just loosen the  slider knobs at each  end of the 
crossrail and move them  to where  you want  them.  Make 
sure  both  sides 
of the crossrails  are  even,  then tighten 
the  slider knobs. 
Be sure  the  cargo  is  properly loaded. Follow 
these guidelines: 
Carrying  small, heavy loads on the roof  is 
Tie the load  to the  tie down  (at either  end of the 
crossrails).  When loading  cargo directly  on the 
roof  panel,  use the  crossrails  to  keep  the  load 
from  shifting. 
not recommended. 
If you  need  to carry  long  items,  move the crossrails 
as  far  apart  as possible. Tie  the load  to the  tie downs 
provided.  Also tie the  load  to the  bumpers. 
Do not tie 
the load 
so tightly  that the crossrails or side  rails 
are  damaged. 
The 
luggage  carrier  has slats,  side  rails  and crossrails 
attached  to  the roof to secure cargo.  The  adjustable  tie 
downs,  at  either  end of the  crossrails,  should be used  to 
secure  loads to  the  luggage  carrier.

NOTICE: 
Loading cargo that weighs  more than 200 Ibs. 
(91 kg) on  the luggage  carrier may damage your 
vehicle.  When you carry  large things, never let 
them  hang over the rear  or  the sides  of your 
vehicle.  When loading  cargo on the  roof  panel,  be 
sure  it rests  on the  slats  and does not  scratch or 
damage  the  vehicle. 
Put  the  cargo  against the side  rails  and fasten  it 
securely  to  the luggage  carrier. Put the main 
weight  as 
far forward as you can  and  move the 
rear  crossrail  forward  as 
far as possible  to keep 
the  load  from  shifting. 
Don’t  exceed  the  maximum vehicle  capacity  when 
loading  your vehicle.  For  more  information  on vehicle 
capacity and  loading,  see  “Loading  Your  Vehicle“ 
in 
the Index. 
To prevent  damage  or loss of cargo as you’re  driving, 
check  now and then to  make  sure the luggage  carrier  and 
cargo  are  still securely  fastened. 
Ashtrays and Cigarette Lighter 
The  ashtray is located in the center  floor  console,  in 
front 
of the shift lever.  Flip the cover to expose 
the  ashtray. 
NOTICE: 
Don’t  put  papers  and  other  things that  burn  into 
your  ashtray. 
If you do, cigarettes  or  other 
smoking  materials  could set them  on fire 
causing damage. 
To  remove  the front  ashtray,  pull the bin  upward. 
The  lighter  is located 
in the instrument panel below the 
climate  controls. 
To use the  lighter, press it in all the 
way,  and let 
go. When  it’s ready, it will pop back 
by  itself.
