DRIVER CONTROLLED
DIFFERENTIAL LOCK (DCDL)
By actuating the electric switch, the driver can
lock or unlock differential action.
The purpose of the DCDL is to provide
maximum vehicle traction and control on
unfavorable road surfaces. When the DCDL is
actuated, a clutch collar completely locks the
differential case, gearing, and axle shafts
together. This feature maximizes traction to both
wheels. The lock position will also protect
against spinout damage to the differential. The
DCDL should not be actuated when favorable
road conditions exist.
OPERATION TIPS
1. The DCDL can be locked or unlocked if the
vehicle is standing still or moving at a
constant low speed when the wheels are not
spinning, slipping, or losing traction.
2. When the DCDL is locked, operate the
vehicle at low speeds. DCDL will not engage
and will disengage in speed higher than 5
MPH (8 km/h).
3. When the DCDL is locked, the vehicle’s
turning radius will increase. This condition is
called “understeer.” The driver must use
caution, good judgment and drive at low
speeds when operating the vehicle with the
DCDL locked.
4. Always unlock the DCDL as soon as the
need for maximum traction has passed and
the vehicle is traveling on a good road.
5. Do not lock the DCDL when the wheels are
slipping or losing traction, or damage to the
axle can result.
6. Do not lock the DCDL when the vehicle is
traveling down steep grades, or potential
loss of vehicle stability could occur.
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, stop the coach, set the transmission
to neutral (N), then push down the rocker switch
located on the dashboard. (Refer to "Controls &
Instruments" chapter). The parking brake will be
applied automatically and a status line pictogram
will appear on the DID to indicate that the front of
the coach is being lowered.
To raise the front of the coach to its normal
height, push up the rocker switch. The front end
will rapidly rise up. The system will release the
parking brake and shift the transmission to the
previously selected range.
NOTE
For further details, consult “
Bendix ABS Operator’s Manual”.
NOTE
The DCDL system is not available on
vehicles equipped with a ZF A-132 drive axle.
NOTE
This coach is equipped with an interlock
system which automatically applies the
parking brake when the kneeling system is
activated.
