NOTE
Tractors/Trucks and trailers built after

the standard method to turn it on. On
trailers built prior to 03/01/2001 verify
trailer ABS system status via the re-
quired external warning light mounted
on the trailer. The indicator light on the
trailer should be yellow and identified
with the letters ABS.

various Cruise Control functions, see

Differential, Inter-Axle Lock
Illuminates when the inter-axle differential
switch is ON thus locking the inter-axle
dif
ferential. This powers the forward rear
and the rear rear differentials equally.
When the switch is turned off (inter-axle
differential unlocked) the engine power is
allowed to flow to any of the four drive tires
based on the differential effect (mostly to
the forward rear differential). This feature is
standard on all tandem axles.
