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.

zones indicate  the 
normal  operating  range. 
Readings 
in the low  warning  zone  may  occur when a large number of 
electrical  accessories are operating in the  vehicle and the engine  is  left at an 
idle for an extended  period. This condilion  is  normal  since the charging 
system  is 
not able to provide full power at engine  idlc. As engine speeds are 
increased, this  condition  should  correct  itself 
;IS higher engine speeds  allow 
the  charging system 
to create  nwximum  power. 
You can only drive  For a short  time with the  reading in either warning  zone.

c 
Run your  engine  only as long  as you  must.  This saves  fuel. When  you  run 
the  engine,  make 
it go a little faster than  just  idle.  That  is, push  the 
accelerator  slightly. This uses less fuel  for the heat that 
you get  and  it keeps 
the battery  (or batteries)  charged. You will need  a well-charged  battery (or 
batteries)  to  restart the vehicle,  and possibly  for signaling later on  with your 
headlights.  Let the heater  run for awhile. 
If you  have  a  diesel engine,  you  may  have to run it at a higher speed to get 
enough  heat.  Then,  shut  the engine  off and  close  the window  almost all the 
way 
to preserve  the heat.  Start the engine  again and repeat this only when 
you feel really uncomfortable  from the cold.  But do it as  little  as possible. 
Preserve  the  fuel  as long 
as you can. To help keep warm,  you can get out of 
the vehicle  and do some  fairly vigorous  exercises every half hour or so until 
help  comes. 
Power  Winches 
If  you wish  to use  a power winch  on your vehicle, only  use it when your 
vehicle 
is stationary  or anchored. 
NOTICE: 
Using  a  power  winch  with  the  transmission  in  gear  may  damage 
the  transmission.  When  operating  a  power  winch,  always  leave 
the  transmission  in  NEUTRAL 
(N). 
Use the  regular brakes, set the parking brake, or block  the wheels to keep 
your  vehicle 
from rolling.
