The intermittent wiping has seven speed settings, 3, 6, 9, 12, 15, 18 seconds and speed dependant. The driver also has the capacity to select these via a switch with seven settings.

The programmable wash and wipe sequence is driver controlled. With a depression of the wash/wipe switch between 40 milliseconds and 1.2 seconds the wash pump will be activated for a duration of 1.2 seconds. When the wash/wipe switch is depressed for longer than 1.2 seconds the wash pump will be activated for the duration of switch depression, a 10 second duration is the maximum available. The wiping system is automatically activated with the depression of the wash switch.

Where fitted, moisture sensitive wiping will be initiated when the vehicle is running and not in the PARK or NEUTRAL gear selection (gear engaged on manual vehicles). The wiper switch must be in the AUTO position.
