µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone. Set the Parking brake.
With the lever in this
position, the transmission locks in
First gear.
If you shif t into First position when
the vehicle speed is above 31 mph
(50 km/h), the transmission shif ts
into Second gear f irst to avoid
sudden engine braking. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal does not work. This procedure
is also used to release the Reverse
Lockout.
Make sure the key is in the
ignition switch LOCK (0) position.
To release the Reverse Lockout,
make sure the key is in the
ACCESSORY (I) position.
