Mercury 1996 Sable Manual page 284

If you must work with the engine running,
avoid wearing loose clothing or jewelry that
could get caught in moving parts. Take
appropriate precautions with long hair.
Do not work on a vehicle in an enclosed
space with the engine running, unless you are
sure you have enough ventilation.
Never get under a vehicle while it is
supported by a jack only. If you must work
under a vehicle, use safety stands.
Keep all lit cigarettes and other smoking
materials away from the battery and all
fuel-related parts.
If you disconnect the battery, the engine must
"relearn" its idle conditions before your vehicle
will drive properly. To find out how the engine
does this, see Battery in this chapter.
Working with the engine off:
1. Set the parking brake fully and make sure
that the gearshift is securely latched in P

2. Remove the key from the ignition after you
turn the engine off.
3. Block the wheels. This will prevent your
vehicle from moving unexpectedly.
