Mercury Sable 1999 - Manual (Page 106)

If the parking brake is fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.
Driving with an automatic overdrive transaxle
Your automatic
overdrive transaxle
provides fully
automatic operation in
either
(Overdrive)
or D (Drive). Driving
with the shift selector
in
(Overdrive) gives
the best fuel economy
for normal driving conditions. For manual control
start in 1 (First) and then shift manually.
If your vehicle is
equipped with a
console mounted
gearshift, you must
press the thumb button
on the side of the
gearshift to move the
gearshift from P
(Park).
To put your vehicle in gear, start the engine, depress
the brake pedal, then move gearshift out of P
(Park).
Hold the brake pedal down while you move
the gearshift lever from P (Park) to another
position. If you do not hold the brake pedal down,
your vehicle may move unexpectedly and injure
someone.
