If you have to leave your vehicle with the engine running, be sure your
vehicle is
in “P7, (Park) and your parking brake is firmly set before you
leave
it. After you’ve moved the shift lever into the “P” (Park) position,
hold the regular brake pedal down. Then, see if you can move the shift
lever away from “P” (Park) without first pulling
it toward you (or, if you
have the console shift lever, without first pushing the button). If you can,
it means that the shift lever wasn’t
fully locked into “P7, (Park).
SHIFTING OUT OF “P” (PARK)
Your Cadillac has a brake-transaxle shift interlock. You have to fully
apply your regular brake before you can shift from
“P7’ (Park) when the
ignition is
in the “Run” position. See “Automatic Transaxle” in the Index.
If you cannot shift
out of “P” (Park), ease pressure on the shift lever --
push the shift lever all the way into “P” (Park) and also release the shift
lever button
on floor shift console models as you maintain brake
application. Then move
the shift lever into the gear you wish. (Press the
shift lever button before moving the shift lever.)
If you ever hold the
brake pedal down but still can’t shift out of “P” (Park), try this:
1. Turn the key to “Off.” Open and close the driver’s door to turn off the

will appear to tell you that the air conditioning compressor has
been turned
off. Air conditioned air will not be delivered to cool your
vehicle. If the pressure returns
to a normal operating range, you must
select “AUTO”, “DEFOG”
, or Defrost to start the compressor. If this
message continues to appear, have the system repaired as soon as
possible to avoid compressor damage.

This message will appear if your battery is not being charged. Have your
electrical system checked by
your Cadillac dealership at your earliest
convenience.

(more than
16 volts). To avoid being stranded have the electrical system

reduce the charging overload
by using the accessories. Turn on the lights,
radio, set the Climate Control on
“AUTO” and the fan speed on “HI”
and turn the rear window defogger on. You can monitor battery voltage
on the Driver Information Center by toggling the “INFORMATION’’
button. When the engine is running, the normal range is
11.5 to 15.5
volts.
BATTERY VOLTS LOW
This message will appear when the electrical system is charging less than
10 volts, or if the battery has been drained. If this message appears
immediately after starting it is possible
that the generator can still
recharge the battery. The battery should recharge after driving a few
miles and the message should go out. If this message appears while
driving or after starting
your vehicle and stays on, have it checked
immediately to determine the cause
of this problem. To help the
generator recharge the battery quickly, you can reduce the load on the
electrical system by turning
off your accessories. You can monitor battery
