To shift to fourth gear, press on the upper part of the
rocker (at the LED). The LED will come on and stay
illuminated until the bottom part of the rocker switch
is pressed.
On vehicles with Allison MD Series automatic trans-
mission or Eaton Autoshift automated transmission, a
push-button shift selector provides four, five, or six
forward ranges and one reverse range. See
Chap-
ter 8 for more information about the push-button shift
selector.
Axle Switches
All axle switches contain a red LED (light-emitting
diode) that illuminates the switch from within when
the switch is turned on (the upper part of the rocker
is pressed). The legend under the LED, if any, is not
visible until the switch is turned on.
IMPORTANT: A guard is positioned around all
axle switches to prevent unintentional activation.
NOTE: For more information on axle switch
function, see
Chapter 8 .
Differential Lock Switch
CAUTION
Differential lock should only be engaged when
the vehicle is stopped or moving slowly at low
throttle. This will prevent internal axle damage.
The differential lock switch is a two-position guarded
rocker switch. See
Fig. 4.24 . It causes the wheels on
each axle governed by the switch to rotate together.
It is also known as side-to-side wheel lock.
To lock the wheels together, press the upper half of
the rocker momentarily (at the LED). To turn off dif-
ferential lock, press the upper half of the rocker
again.
When the panel lights are on, the double-axle icon is
backlit in green.
IMPORTANT: The differential lock switch is
guarded to prevent unintentional switch activa-
tion. If the LED in the switch begins to blink dur-
ing normal operation, when the switch has not
been activated, this indicates an error condition.
Bring the vehicle to an authorized Freightliner
service facility as soon as possible.
Interaxle Lock Switch
CAUTION
The interaxle lock should not be engaged on a
vehicle with obviously spinning wheels. Engage-
ment at high speed or power can damage the
axle(s).
The interaxle lock switch is a two-position guarded
rocker switch installed on vehicles with dual drive
axles. See
Fig. 4.25 . It causes both axle shafts to
rotate together.
To lock the axles together, press the upper half of the
rocker momentarily (at the LED). To turn off interaxle
lock, press the upper half of the rocker again.
When the panel lights are on, the double-axle icon is
backlit in green.
IMPORTANT: The interaxle lock rocker switch is
guarded to prevent unintentional switch activa-
tion. This switch does not have a diagnostic
blink function when inactive.
