Kickdown
Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.

gear depending on the engine speed.

Rocking the vehicle free
Shifting back and forth between transmission
positions h and k can help to free up the
vehicle if it gets stuck in mud or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift repeatedly
between transmission positions h and k,
move the DIRECT SELECT lever up and down
beyond the pressure point.

X

use the left-hand steering wheel paddle
shifter (Y page 152) to select a lower gear,
even if cruise control or Active Distance
Assist DISTRONIC is activated.
