For a vehicle with tandem axles, there are several
differential lock switch options available:
•
one switch to control the differential lock on
only one of the drive axles (this switch will
show only one dot on one drive axle, varying
slightly from the switch shown in
Fig. 5.19 ).
•
one switch to control the differential locks on
both drive axles (
Fig. 5.19 ).
•
two switches, each of which controls the differ-
ential lock on one drive axle.
When the differential lock switch is pressed, the LED
in the switch blinks until the differential lock is en-
gaged. When the differential lock is fully engaged,
the LED illuminates steadily.
Interaxle Lock Switch
The interaxle lock switch ( Fig. 5.20 ) allows the driver
to lock the drive axles together, causing the drive
axle shafts to rotate together. Use this feature only
under adverse road conditions where greater traction
is needed.
NOTICE
The interaxle lock should only be engaged when
the vehicle is moving slowly at low throttle. En-
gagement at high speed or power can damage
the axle(s).
When the interaxle lock switch is pressed, the LED in
the switch blinks until the interaxle lock is engaged.
When the interaxle lock is fully engaged, the LED
illuminates steadily.
Cruise Control Switches
NOTE: See Chapter 10 for detailed information
about cruise control operation.
Cruise control is activated by two dash-mounted
switches (
Fig. 5.21 ).
•
On/Off Switch—a two-position rocker labeled
SPD CNTL on the lower half of the switch.
When cruise control is on, an amber light illu-
minates the top part of the switch.
•
Set/Resume Switch—a three-position paddle
switch labeled RES/ACC above the paddle and
SET/CST below the paddle.
NOTICE
When the cruise control is engaged, do not at-
tempt to shift gears without using the clutch
pedal. Failure to follow this precaution will result
in a temporarily uncontrolled increase in engine
speed. Transmission damage and gear stripping
could result.
