Torque Lock
The parking brake should be set first whenever leaving the driver's seat. I f
you are parked on a hill and the transmission is placed in
P (Park) before
the parking brake is
set,
the weight of the vehicle may put
too
much force
on the parking pawl in the transmission. It
may
be difficult to
pull
the selector
lever out
of P (Park). This is called "torque lock." 'To prevent this, the parking
brake should be set BEFORE moving the selector lever
to P (Park).
When preparing to move the vehicle, the selector lever should be. moved out
of P (Park) B€FORE releasing the parking brake. Set the parking brake first,
Then release the transmission from P (Park),
,
even on level surfaces.
I f "torque lock" does occur, you may need
to have another vehicle nudge this
vehicle uphill
to
take some of the pressure
off the transmission while you pull
the selector lever out of
P
(Park).
