DRIVING AND OPERATING

Automatic Transmission

The shift pattern is displayed in the
top of the shift lever. The selected
gear position will illuminate red on
the shift lever, while all others will be
displayed in white. If the shift is not
immediate, as in very cold conditions,
the indicator on the shift lever may
blink until it is fully engaged.
The shift lever always starts from a
center position, represented by an up/
down arrow on the shift pattern. After
releasing the shift lever, it will return
to the center position.
