If your vehicle has no electrical power, the electrical
solenoid lock must be overridden to shift from
PARK
(P)
to NEUTRAL (N). Follow these steps:
1. Push the base of the leather shift lever boot forward
with your thumb.
2. Lift the boot and find the white solenoid lever.
3. Move the white
lever toward the
driver's side to
unlock it.
4. While holding the white solenoid lever in the unlock
position, press the shift lever button and shift
into NEUTRAL (N).
5 . Release the solenoid lever and snap the boot back
into place.
Don't have your vehicle towed on the drive wheels
unless you must. If the vehicle must be towed on the
drive wheels, be sure not to exceed 35 mph (56 km/h)
and not to travel more than 50 miles (80 km) or your
transmission will be damaged. The drive wheels have to
be supported on a dolly.
