IVT — Starting in Cold Weather

LX1026066-UN-10MAY01

LX1037175-UN-06JUN06

To avoid damage at temperatures below freezing, an automatic function prevents the drive system from engaging too soon. After the engine has 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 corner park, code UIC 305058.01 (INFORMATION FOR OPERATOR: Transmission warm-up routine cannot be activated, park lock should be engaged) appears on the display.

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: The engine speed may rise up to 1500 rpm during the warm-up routine.
