TAG AXLE SUSPENSION
SYSTEM
Freightliner
®
Chassis
(Model 42E only)
Your coach is equipped (Model 42E only)
with a Tag Axle Suspension System, which is
designed to increase the Gross Vehicle Weight
Rating (GVWR). This system is to be used when
the rear suspension/axle will be loaded to a
weight greater than 20,000 lbs. When certain
conditions arise, air can be exhausted from the air
springs to improve maneuverability or traction
on the rear axle by operating the Tag Axle switch
(located on dash).
Tag Axle Switch Operation
Tag Dump Position
•
Press and Hold Tag Axle switch in the TAG
DUMP position for the Tag Axle air pressure
to remain reduced and maintain the
maneuverability or traction benefit desired.
Auto Dump Position
•
This mode is activated automatically when in
reverse gear, when the Tag Axle switch is in
the MIDDLE position. The Auto Dump
feature gives you better maneuverability
while driving in reverse.
Off Position
•
The Tag Dump mode is inactive when the Tag
Axle switch is in the OFF position.
WARNING
Do not activate the engine exhaust
braking system while on icy or extremely
wet roads or in any other situation where

or loss of vehicle control.
