Seats
General Information
Unless otherwise noted, all seat adjustments should
be made while seated and before the engine is
started.
Due to the maximum adjustability of mid- and high-
back air suspension seats, it is possible to combine
the seat back recline adjustment and the seat slide
adjustment so that the seat back contacts the back-
wall. It is the responsibility of the driver to adjust the
seat to prevent damage to the seat and the cab inte-
rior.
WARNING
Keep hands, tools, and other objects away from
the scissor points under the seats. Failure to do
so could cause personal injury.
Seat Adjustments
The following is a description of adjustments that can
be made to various Freightliner-installed seats. Not
all seats have all of the adjustments listed below.
See
Fig. 5.1
.
1.
Back Cushion Tilt: This adjustment enables the
back cushion to pivot forward or backward.
2.
Lumbar Support: Lumbar support changes the
shape of the seat back to give more or less sup-
port to the occupant’s lumbar (lower back) area.
This adjustment is either mechanical or air con-
trolled, depending on make and model of the
seat.
3.
Isolator: This feature (also referred to as back-
slap isolator or Chugger-Snubber
®
) reduces the
amount of road shock by isolating the occupant
from the motion of the vehicle, and allowing the
upper seat to move in a simple pendulum mo-
tion. A lockout feature is used whenever the iso-
lator is not desired.
