L

N = Neutral – Disconnects drive to the
wheels. Use the parkbrake when stopping
temporarily.

D = Drive – All six forward gears are
changed automatically.

S = Sport – All six forward gears are
changed automatically with modified gear
shift points.

Stationary vehicle

When the vehicle is stationary the gear
selector may be left in D, or S, unless the
vehicle is to be parked. When stopping for
extended periods, either select P or apply
the parkbrake and select N.

Shift inhibit

Reverse is inhibited when the vehicle is
moving forward.

Note: Reverse inhibit will not function in
limp-home mode.

Note:

The engine is limited to a maximum
speed of 4 500 rev/min. when N or P
is selected.

After selecting forward or reverse
drive ranges from N or P, wait briefly
for the transmission to engage before
accelerating.

Automatic operating modes

There are two available automatic modes:

D - Drive: All six gears are changed
automatically. The shift points are
determined by accelerator pedal position
and road speed to provide the best
balance of performance, refinement and
fuel economy for the large majority of
driving conditions.

S - Sport: The transmission operates
automatically, but the gearshift points are
modified to maximise the vehicle
response in demanding driving
conditions. This mode is not suitable for
town or highway cruising.

The automatic modes also offer additional
features:

Kick-down: Is operated when the
accelerator pedal is fully depressed
beyond the normal operating spring
pressure to provide maximum engine
performance. Kick-down is used in
circumstances where rapid acceleration
is required, such as when overtaking.

Kick-down causes the transmission to
change down to the lowest gear possible
to achieve maximum acceleration. The
gear engaged depends on the road speed
at the time of kickdown.

Driver type recognition: The
transmission monitors driving style and in
combination with sensors in the vehicle,
varies the shift schedule, fast-off, corner
recognition and shift adapt under braking
functions proportionally with driving style.

Note: This feature is only active in S -
Sport mode.

Fast-off: Activated when rapidly lifting-off
the accelerator pedal and takes account
of road gradient. This feature inhibits
up-shifts enhancing performance.

Note: This feature will vary its activation,
dependant upon the driver type if S -
Sport is selected.
