NOTICE: 
After  you’ve  used  the  coolant  heater, be  sure  to  store  the  cord  as 
it  was  before  to keep 
it away from moving  engine  parts.  If  you 
don’t, 
it could  be  damaged. 
How  long should  you keep  the coolant  heater plugged in? The  answer 
depends  on  the weather,  the  kind  of  oil  you  have. and  some other things. 
Inste.ad  of  trying 
to list everything  here, we ask  that  you  contact your GM 
dealer in the area  where  you‘ll be parking your vehicle. The dealer can give 
you  the  best  advice  for that particular  area. 
Automatic  Transmission 
There  are several different positions  for your  shift lever. 
If your vehicle  is equipped with an  automatic  transmission, it now  features 
an  electronic  shift position  indicator 
within the instrument cluster.  This 
display  must  be  powered  anytime the shift lever is  capable 
of being moved 
out  of  the 
PARK (P) position.  This means that if your  key  is in the OFF 
position, but  not locked,  there will be a small current drain on your battery 
which  could discharge your battery  over 
a period  of time. If you  have  a need 
to  leave  your key 
in the ignition in the OFF position  for an extended  period 
for  any  reason, 
it is recommended  that you disconnect  the battery  cable 
from  the battery  to prevent  discharging  your battery. 
PARK  (P) -This  locks your rear wheels.  It’s  the best position to use 
when  you start  your  engine  because your vehicle can’t move easily.

Electrochromic  Inside  Rearview  Mirror  with  Compass (Option) 
Your  vehicle  may have  an optional electrochromic  inside rearview mirror. 
An  electrochromic  inside rearview  mirror,  when 
on, automatically dims to 
the proper  level to minimize glare  from lights behind  you after  dark. 
The mirror also includes  an eight  point  compass  display in the upper right 
corner 
of the mirror face. When on, the  compass automatically calibrates as 
the vehicle is driven. 
To use the electrochromic  mirror only, move the switch  at the bottom  of the 
mirror to  the 
M position. To use the electrochromic  mirror as well as the 
compass,  move the switch  to the 
C/M position.  To turn  both  features off, 
move the switch to the OFF position. 
Compass Operation 
When the ignition  is on and the mirror switch  is in the C/M position, the 
compass  display 
will show two  character  boxes for approximately  two 
seconds. 
If, after  two seconds,  the display  does not show  a compass heading 
(“N”  for  North, for  example),  there may  be  strong magnetic  field interfering 
with the  compass.  Such  interference may include  magnetic antenna mounts, 
a magnetic  note  pad holder,  or a similar magnetic item. If removing these 
items  does  not correct the condition,  see your 
GM dealer  for assistance. 
When  cleaning 
the mirror, use a paper towel  or similar material  dampened 
with  glass  cleaner. 
Do not spray glass cleaner directly on the mirror as that 
may cause  liquid cleaner to  enter the mirror housing.

Compass Variance 
Under certain  circumstances,  as during a long  distance  cross-country  trip, it 
will be necessary  to adjust the  compass to compensate  for  cornpass 
variance.  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. 
To adjust for compass  variance: 
1. Press and  hold the CAL  switch,  located  at the bottom  of the mirror 
housing,  for  five  seconds 
until a zone number appears in the display. 
2. Find  your  current  location  and variance zone number  on the  following 
zone  map. 
3. Press and  hold  the CAL switch until the new zone number  appears in 
the display. After  you release  the switch,  the display will show a 
compass  direction  within  a few  seconds.

Warning  Lights  and Indicators 
This  part describes  the warning  lights and gages that  may  be  on  your 
vehicle.  The pictures  will help  you locate them. 
Warning lights and  gages can signal  that something  is wrong before 
it 
becomes  serious  enough to cause an expensive repair  or replacement. 
Paying attention  to your warning lights  and gages  could also save  you or 
others  from  injury. 
Warning  lights  come  on when there  may  be or is a problem 
with one  of your 
vehicle’s  functions. 
As you will see in the details  on the  next  few  pages, 
some  warning  lights come on briefly when  you start  the engine  just 
to let 
you  know they’re  working.  If  you are familiar 
with this section,  you should 
not  be alarmed when 
this happens. 
Gages  can  indicate when there  may  be or is a problem  with one of your 
vehicle’s  functions.  Often gages and warning lights work together to let  you 
know when there’s 
a problem  with your vehicle. 
When  one 
of the warning lights  comes on and stays on when  you are 
driving,  or when  one 
of the gages  shows there may  be  a problem,  check the 
section that tells  you what 
to do about it. Please  follow  this manual‘s  advice. 
Waiting to 
do repairs  can  be costly - and  even dangerous. So please  get to 
know your warning  lights and gages.  They’re  a  big help.
