Active mast rear tilt speed control
• At a high lift, the mast has a backward tilt speed controlled 
(slowed down) irrespective of a load. If the high lift is changed 
over to the low lift while tilting the mast backward, the control-
led speed will last.
• At a low lift, the mast can be tilted at the full speed irrespec-
tive of a load. If the mast is tilted backward at a low lift with 
the tilt knob switch pressed, the mast has a backward tilt 
speed controlled (slowed down) as long as the tilt lever knob 
switch is pressed.
• If the low lift is changed over to the high lift while tilting the 
mast backward, the controlled speed will last as long as the 
tilt lever knob switch is pressed. And the mast may be tilted 
backward at the full speed so long as the tilt lever knob switch 
is not pressed.
Key-lift interlock
With the engine killed (the ignition switch positioned at OFF), the
fork will not move down even if the lift lever is so operated.
Active steering synchronizer
If the steering wheel knob is not angularly matched with tires,
such an out-of-position will be automatically corrected while
turning the steering wheel. Thus, the knob is kept at a constant
position relative to tires. 
If SAS feature should fail:
An SAS model is controlled with a controller, a sensor and vari-
ous actuators. If any of them is found not to be operating nor-
mally, it tells you that: 
• Steering wheel knob out-of-position may not be corrected.
• Such features as automatic fork leveling control, active mast 
front tilt angle control and active mast rear tilt speed control.
• Swing lock may not be unlocked.
If any of the phenomena referred to above should take place,
• SAS warning lamp will blink.
• Error code will be displayed in hour meter.
• Buzzer will sound.
Thus, the operator will be informed. In such event, move the 
vehicle to a safe location and ask a BT dealer for a repair.
