Axle Shift Switch
CAUTION
To prevent transmission and axle damage, make
sure the automatic transmission is in high range
when performing an axle shift with the vehicle
moving.
The axle shift switch is a two-position guarded rocker
switch installed on vehicles with two-speed axles.
See
Fig. 4.26 .
To shift the axle from low speed to high speed, press
the upper half of the rocker momentarily (at the
LED). To turn the axle shift off (switch from high
speed back to low speed), press the upper half of
the rocker again.
NOTE: On vehicles with tandem drive axles,
there is an interlock that prevents a 2-speed
axle from shifting whenever the interaxle lock is
on.
When the panel lights are on, the AXLE SHIFT leg-
end is backlit in green.
IMPORTANT: The axle shift switch is guarded to
prevent unintentional switch activation. If the
LED in the switch begins to blink during normal
operation, when the switch has not been acti-
vated, this indicates an error condition. Bring the
vehicle to an authorized Freightliner service fa-
cility as soon as possible.
AWD Controls
The AWD switch allows the driver to direct power to
the steer axle. For more information about transfer
cases and driven steer axles, see
Chapter 8 .
AWD Operation Switch
The AWD operation switch (LOCKED AWD) is a two-
position rocker switch. See
Fig. 4.27 .
To engage the steer axle, press the upper half of the
rocker switch. To disengage it, press the lower half of
the switch.
Transfer Case Range Switch
CAUTION
Before selecting the neutral (N-TRL) position,
stop the vehicle and set the parking brake to pre-
vent the vehicle from rolling and causing damage
and/or personal injury.
NOTICE
To prevent damage to the transfer case and the
driveline, stop the vehicle and put the transmis-
sion in neutral before using the range switch.
IMPORTANT: Use this switch only when the
steer axle has been engaged.
There are two transfer case range switches: a two-
position rocker switch with LO and HIGH RANGE,
and a three-position switch that has a neutral (N-
TRL) position in the middle for vehicles with a power
take-off (PTO) unit. See
Fig. 4.28 .
For operating guidelines for Meritor MTC transfer
cases, see
Chapter 8 .
