Sitting Posture
Before driving, adjust the seat to support good sitting
posture as shown in
Fig. 7.1. Good posture supports
the safe operation of the vehicle and the driver’s
fitness and comfort. When correctly seated, all
instruments and controls should be within easy reach
and the driver should have a clear view of the road
and mirrors.
ISRI Elite High Back Seat
NOTE: The seat should only be adjusted when the
vehicle is parked.
The seat is designed to hold a maximum weight of
330 lb.
The ISRI Elite seat has ten different features; the
controls are shown in
Fig. 7.2 .

Backrest Tilt: Pull the handle out completely
and lean back or forwards to adjust the backrest
tilt. Release the handle when the correct position
is achieved. The backrest has a 52 degree range
of movement.
When adjusted, the backrest inclination should
allow the driver to reach the steering wheel with
angled arms.

flow through the cushions can cause the seat to
overheat and damage the seat.
