Operation Manual

167Starting and driving
If the gear selector lever is moved from position D to 1, a
change-down to 3rd gear will occur at about 110 mph (180 km/h).
A change-down to 2nd gear will occur at about 75 mph (120 km/h)
and to 1st gear at about 40 mph (65 km/h).
When position 1 is selected, all the other gears will be locked out.
Manual gear-changing is not recommended on slippery roads.
If one of the drive wheels spins excessively, the engine torque will
be reduced to avoid damaging the transmission
Adaptive gear-change patterns
Adaptive gear-change patterns are selected automatically depend-
ing on the engine load. This function applies in the Normal and Sport
modes.
The change occurs at a higher rotation speed and the gear remains
engaged for a longer period, if the control module senses that the
load does not drop. These change patterns avoid unnecessary gear
changes when, for example, driving on long inclines with a trailer,
and to prevent overheating of the transmission oil. This function cuts
in automatically if the oil becomes too hot, to protect the transmis-
sion from damage, and lowers the oil temperature.
The adaptive change pattern function is not activated at speeds over
93 mph (150 km/h). If a pattern is in operation when this speed is
exceeded, it will be maintained until the control module senses that
a more suitable one can be activated.
The adaptive gear-change pattern function is deselected when:
• Winter mode is selected.
• The engine is switched off.
• The load is reduced by so much that this function is no longer
required.
• “Automatic transmission fault indicator” appears on the
main instrument panel, see page 165.
