If your speed drops below 20 mph (30 km/h), or if the
engine is not running smoothly,
you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good performance.

If you skip more than one gear when you
downshift, or if you race the engine when you
downshift,
you can damage the clutch or
transmission.

Leaving Your Vehicle With the Engine
Running (Automatic Transmission Models
Only) Torque Lock (Automatic Transmission)
If you
are parking on a hill and you don’t shift your
transmission
into PARK (P) properly, the weight of the
vehicle may put too much force
on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out
of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To find out how, see “Shifting Into
PARK (P)” in the Index.
When you are ready to drive, move the shift lever out of
PARK (P)
before you release the parking brake.
If “torque lock” does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the transmission,
so you can pull the
shift lever out of PARK
(P).
