5 Driving & Shifting
5.1 Fully Automatic Shifting
COMPUSHIFT II uses information about throttle position, vehicle speed and gear level to decide when to shift.
As you increase the amount of applied throttle, COMPUSHIFT II decides to upshift at increasingly higher
vehicle speeds.
When you drive away with light throttle, COMPUSHIFT II upshifts relatively soon.
If you give the engine full throttle, COMPUSHIFT II will upshift at a higher vehicle speed and engine RPM.
Shift firmness is controlled in much the same way as shift speed.
Shift firmness is related to throttle position or engine load, not vehicle speed. This is because a firm shift is
required to prevent slippage when the engine is making more torque. Under less power, the shift can be
gentler.
5.2 Using a Paddle Shifter or Switch-Shift (Optional)
If you utilize the Switch-Shift feature, you can manually upshift and downshift the transmission via a pair of
pushbuttons or paddles. Here's how the feature works:
When you first put the transmission in gear, shifting will be automatic.
Press either the upshift or downshift button to change the transmission gear. The display will show "S" in
the GEAR meter instead of "A".
After a button press, the transmission will stay in switch shift mode and will not automatically shift without
another button press.
At a stop in automatic mode, the transmission is normally in 1st gear. If you press the downshift button, the
transmission remains in 1st gear, but changes to Switch Shift mode.
You must downshift manually when coming to a stop.
To cancel switch shift mode and return to fully automatic shifting, hold the downshift or upshift button for 2
seconds.
Moving the shift lever also exits you out of Switch-Shift mode, and COMPUSHIFT II reverts to automatic
mode.
Many transmissions do
not
have the ability to engine brake under automatic control. This means you
cannot
control your speed on a descent using the Switch-Shift controls. If you wish to use the engine while
decelerating, you
must
use the shift lever.
