Seat
The USSC Q91™ driver’s seat is
equipped with a pneumatic
suspension system, air adjustable
upper and lower lumbar support, a
retractable three-point seat belt, and
various electrical and manual
controls which enable a wide range
of comfort adjustments.
Manual Controls
1. 4-Way Adjustable Headrest
Support

lower it. Pull forward or push
back on the top of the headrest
to adjust the angle.
2. Backrest Inclination Handle
Adjust backrest by turning this
knob clockwise or counter
clockwise.

cushion angle to be adjusted
from 1° to +9°.
4. Air Lumbar Adjustments
Three rocker switches are used
to adjust the air lumbar
requirements.
Push switch forward to inflate

deflate. The switch next to the
auto actuator button is for the
bottom lumbar, next is for the
middle lumbar and then the top
lumbar adjustments.
5. Auto Actuator Button
Pressing this button activates
an air cylinder which in turn
releases the tracks so that the
seat can be moved foreward
and backward.
WARNING
Stop the vehicle and apply the
parking brake before adjusting
the seat. Failure to do so could
result in loss of vehicle control,
causing personal injury and/or
vehicle damage.
NOTE
A switch is installed inside the
front seat cushion which will
cause the Park Brake LED light
to illuminate and an audible
alarm to sound if the driver
leaves the seat without applying
the parking brake.
