Isolator
Also called a Chugger Snubber
®
, the isolator reduces
the amount of road shock by isolating the occupant
from the motion of the vehicle and allowing the seat
to move in a simple pendulum motion. To use the
isolator feature, turn the isolator handle to the hori-
zontal position. Turn the isolator handle down when
the isolator feature is not desired.
Lumbar Support
To adjust the lumbar support, use the lumbar support
switch on the side of the seat to give more or less
support to your lower back.
Bottom Cushion Front Height
To adjust the height of the front of the bottom cush-
ion, lift the bottom cushion front height adjustment
handle, and pull forward or push back to the desired
setting.
Seat Belts and Tether Belts
General Information
Seat belt assemblies are designed to secure persons
in the vehicle to help reduce the chance of injury or
the amount of injury resulting from accidents or sud-
den stops. For this reason, Daimler Trucks North
America LLC urges that the driver and
all
passen-
gers, regardless of age or physical condition, use
seat belts when riding in the vehicle.
WARNING
Always use the vehicle’s seat belt system when
operating the vehicle. Failure to do so can result
in severe personal injury or death.
Seat belt assemblies in Daimler Trucks North
America (DTNA) vehicles meet Federal Motor Ve-
hicle Safety Standard 209, "Type 1" and "Type 2" re-
quirements.
When transporting a child, always use a child re-
straint system or the vehicle seat belts as appropri-
ate. To determine whether a child restraint system is
required, review and comply with applicable state
and local laws. Any child restraint used must comply
with Federal Motor Vehicle Safety Standard 213,
"Child Restraint Systems." When providing a child
restraint system, always carefully read and follow all
instructions pertaining to installation and usage for
the child. Make certain the child remains in the re-
straint system at all times when the vehicle is in mo-
tion.
In addition to seat belt assemblies, tether belts are
installed on suspension-type seats. Tether belts help
secure the seat to the floor and are intended to re-
strain the seat and seat belt in case of an accident or
sudden stop.
IMPORTANT: Seat belts have a finite life which
may be much shorter than the life of the vehicle.
Regular inspections and replacement as needed
are the only assurance of adequate seat belt
security over the life of the vehicle.
