AutoPowr - Cold Weather Starting

To avoid damage at temperatures below freezing, an automatic function prevents the drive system from engaging too soon. After the engine is started, diagnostic trouble code UIC 305057.01 (INFORMATION FOR OPERATOR: Transmission Warm-up Routine is Active) appears on the display.

The warm-up routine can only be started if the reverser lever is in the "corner park" position. If the reverser lever is in any position other than park, code UIC 305058.01 (INFORMATION FOR OPERATOR: Transmission Warm-up Routine Cannot be Activated, Park must be Engaged) is displayed.

The time required for the transmission to warm up will vary depending on temperature:

Temperature range	Warm-up time
above -7° C (19.4° F)	none
between -8° C (17.6° F) and -15° C (5° F)	96 seconds
between -16° C (3.2° F) and -20° C (-4° F)	156 seconds
between -21° C (-5.8° F) and -30° C (-22° F)	246 seconds

At temperatures below -30° C (-22° F) only the transmission input shaft is turned. The warm-up routine starts as soon as the transmission oil temperature has reached -30° C (-22° F).

NOTE: Engine speed may rise up to 1500 rpm during the warm-up routine.
