LOCKING THE DCDL
When encountering poor road conditions where
maximum traction is needed, follow the
recommended procedures:
1. Without the wheels spinning, slipping or
losing traction, flip the DCDL control switch
to the “LOCK” position while maintaining a
constant vehicle speed.
2. Let up momentarily on the accelerator to
relieve torque on the gearing, allowing the
DCDL to lock.
3. When the DCDL is fully locked, the vehicle
will have an “understeer” condition when
making turns. Proceed cautiously over poor
road conditions.
UNLOCKING THE DCDL
When the vehicle can safely operate and driving
conditions have improved, disengage the DCDL
following the recommended procedures:
1. Flip the control switch to the “UNLOCK”
position, when the vehicle is stopped or when
traveling at low speed while the wheels are
not spinning, slipping or losing traction.
2. Let up momentarily on the accelerator to
relieve torque on the gearing, allowing the
DCDL to unlock.
3. Resume driving at normal speed using good
driving judgment.
KNEELING SYSTEM
This system lowers the front end, enabling
passengers to get on and off the coach without any
difficulty.
To operate:
1. Stop the coach and apply the parking brakes
2. Set the transmission to neutral (N) ;
3. Momentarily press the rocker switch
downwards to lower the front end of the coach
4 inches (100 mm). Refer to "CONTROL
SWITCHES" on page12 in Section 4
Controls and Instruments.
A pictogram will appear in the DID status line
indicating that the coach is being lowered.
To raise the front of the coach to normal height;
1. Momentarily press the rocker switch
upwards. The front end will rapidly rise up.
NOTE
The parking brakes must be applied to allow the
use of the kneeling.
NOTE
Kneeling is disabled when the entrance door is
open.
CAUTION
Avoid parking the coach too close to the sidewalk
or to other obstacles which could damage the
coach during kneeling.
HI-BUOY
The coach may be equipped with the optional front
Hi-Buoy or full Hi-Buoy. The front Hi-Buoy system
has the same functions as front kneeling. In addition
it enables passengers to get on or off the coach
easily by raising the front end about 4 inches (100
mm), which may prove useful when the dock is
higher than usual. The front Hi-Buoy is combined
with front kneeling to increase flexibility of the
system. Refer to "CONTROL SWITCHES" on
page12 in Section 4 Controls and Instruments.
The full Hi- Buoy system raises the whole coach
about 4 inches (100 mm). It can be used to enable
passengers to get on or off the coach easily, and to
safely travel roads with high obstacles. Refer to
"CONTROL SWITCHES" on page12 in Section 4
Controls and Instruments.
NOTE
The Hi-Buoy system does not operate when the
coach is traveling over 5 mph (8 km/h).
Consequently, the driver cannot inadvertently
operate the Hi-Buoy system at higher speeds.
LOW-BUOY
This system lowers the coach about 4 inches (100
mm). It enables the coach to drive under overhead
