Gearshift Modes
Automatic Mode
When the gear selector lever is operated in the right half of
the selector gate ('A' showing in the instrument panel
display), the transmission is in Automatic mode.
The gearbox functions as a standard automatic five speed transmission. The
selector lever may be placed into the P, R, N or D positions. When D is
selected, gearshifts will be made automatically at points dependant on
vehicle speed, throttle position and engine load.
Sport Mode
The Sport mode can be selected by moving the gear selector
lever to the left from the 'D' position. The Sport warning lamp
on the instrument panel will illuminate on entering Sport
mode.
Sport mode may be cancelled by moving the selector lever back to the right
half of the selector gate to return to Auto mode. Sport mode is also cancelled
by selecting a gear in Touchtronic mode.
Touchtronic Mode
From the Sport position, Touchtronic mode is selected by any forward or
rearward movement of the selector lever or by pressing one of the steering
wheel gearshift buttons.
Any forward movement of the selector lever will engage the next higher
gear. Any rearward movement of the selector lever will engage the next
lower gear. The lever will return to the centre position after each movement.
In Touchtronic mode, all gearshifts are under driver control. The number of
the current gear appears in the digital selector display.

C - Driving
1-C-15 When at a standstill, Touchtronic mode is engaged by pushing the lever
forward or by pressing the '+' button on the steering wheel. The gearbox
controller will always initially select 2nd gear. If first gear is required, it may
be selected by pulling the lever rearwards or by pressing the - button on the
steering wheel.
When Touchtronic mode is engaged whilst driving, the transmission will
remain in the current gear. Gearshift control will revert from automatic to
manual control.
Touchtronic mode may be deselected whilst driving by moving the selector
lever to the right. The transmission will revert to Automatic mode and may
shift to a more appropriate gear.
Minimum Upshift Speeds
The transmission controller will only allow upshifts when vehicle speed is
above the following minimum limits:
Upshifts enabled 2nd to 3rd gear above 15 km/h (10 mph)
3rd to 4th gear above 35 km/h (22 mph)
4th to 5th gear above 52 km/h (32 mph)
During deceleration, if road speed falls below the minimum limit for each
gear, the transmission will automatically downshift to eliminate the possibility
of the engine stalling.
Gearshift Inhibit
In Touchtronic mode, any attempted gearshift which would cause the
engine speed to rise over 6,500 rpm, or fall below 1,300 rpm will be
prevented by the transmission controller.

Additional Automatic Gearbox Functions
Kickdown (Automatic and Sport Modes Only)
If maximum power is demanded from the engine by opening the throttle to
more than about 95%, the kickdown function is automatically actuated.
With kickdown in operation, the gearbox may shift to the next lower gear
and further upshifts will occur at much higher engine speeds than when
using modest throttle openings. This mode is useful to achieve maximum
acceleration when, for example, overtaking another vehicle.
Torque Converter Lock-up
When driving in 3rd, 4th or 5th gears, a further change takes place within
the transmission. The torque convertor, transmitting power from engine to
transmission, will lock to improve the transmission efficiency. This is a
completely automatic function of the transmission system and will occur at
predetermined speeds.
