Manual Transmission
Engine Speed Limiter
If you exceed the maximum speed
for the gear you are in, the engine
speed will enter into the tachometer's
red zone. If this occurs, you may feel
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.
Before downshifting, make sure the
engine will not go into the
tachometer's red zone.

Reverse Lockout
6-speed manual transmission only
The manual transmission has a
lockout so you cannot accidentally
shift from any forward gear to
reverse while the vehicle is moving
at a certain speed. If you cannot shift
to reverse when the vehicle is
stopped, do the following:
Move the shift lever in sequence.
1. With the clutch pedal pressed,
move the shift lever to the first/
second gear side of the neutral
gate, then shift to reverse.

2. If you are still unable to shift to
reverse, apply the parking brake,
and turn the ignition key to the
ACCESSORY (I) or LOCK (0)
position.
3. Press the clutch pedal, and shift to
reverse.
4. With the clutch pedal still pressed,
start the engine.
If you need to use this procedure to
shift to reverse, your vehicle may be
developing a problem. Have it
checked by your dealer.
