146 Controls in detailAutomatic transmissionAccelerator position
Your driving style influences the transmis-
sion’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting

resistance.
The transmission shifts into a lower
gear.

Ease on the accelerator when you have
reached the desired speed.

mode, only 2nd gear and reverse gear can
be activated.
Stop the vehicle.

Move selector lever toP.

Turn off the engine.

Wait at least ten seconds before re-
starting.
