Gearshift paddles (example illustration)
1Left shift paddle: limiting gear range or
downshift (in MANUAL program mode)
2Right shift paddle: extending gear
range or upshift (in MANUAL program
mode)
The following instructions describe opera-
tion of the steering wheel gearshift control
when driving in the automatic program
modeC orS.Limiting gear rangeBriefly pull left shift paddle1.
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously
limits the gear range of the transmis-
sion (
page 176).Extending gear range
Briefly pull right shift paddle2.
The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the transmis-
sion.
iYou cannot shift with the steering wheel
gearshift paddles when the gear selector lever is
in positionP,N orR.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iTo avoid overrevving the engine when down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be
exceeded.
iIf you press on the accelerator when the en-
gine has reached its rpm limit, the transmission
will upshift beyond any gear range limit selected.
