NOTE
To maximize the drive axle wheel traction, the
tag axle will automatically unload when the
snow chain system is active. The tag axle air
springs will return to normal pressure once this
system deactivates.
Engine Stop Override (With Automatic Fire
Detection And Suppression System)
Press the Engine Stop Override
switch on the dashboard or the Delay
Engine Stop switch on the AFSS
protection panel to delay the engine
shutdown and extinguisher discharge
by an additional 15 seconds.
CAUTION
Use this function if you are not
prepared to bring the vehicle to a safe
stop (i.e. on a railroad track, in
intersection).
This switch is functional only if the
vehicle
is equipped with the
Automatic Fire Detection and
Suppression System.
Traction Control System Mud/Snow Mode
On certain road conditions, it may
be useful to retard the intervention
of the traction control system TCS
during vehicle acceleration. The
Mud/Snow function allows greater
engine power and more wheel spin
during TCS operation. This function
may be helpful to set the vehicle in
motion on iced roads, for example.
Press the Mod/Snow switch to turn
on this function. The TCS icon
blinks slowly in the DID when the
TCS Mud/Snow mode is active.
Always
remember to turn the
Mud/Snow feature off when driving
on a firm road surface.
A new ignition cycle or a second
pressing of the Mud/Snow switch
will turn this function off.
Transmission Retarder
Press this rocker switch to activate
the transmission retarder. Refer also
to
"Transmission Retarder” in
OTHER FEATURES section.
NOTE
Deactivating the transmission
retarder will turn on the indicator light
located at the front of the coach.
Secondary Use - Regeneration Inhibit Override
Flip this rocker switch 4 times (4 transitions from
OFF to ON) within 2 seconds to override the
regeneration inhibit function through geofencing
and allow parked regeneration.
Starting Switch
Use this switch to start the engine.
The ignition switch has to be in the
''ON'' position.
Fast Idle
For extended idling periods, run the
engine at fast idle. Press down this
rocker switch to engage fast idle.
This increases the engine speed to
approximately 1,000 rpm. Return to
normal idle before driving or when
stopping the engine.
CAUTION
If the parking brake is released and/or the
transmission is engaged with the engine
running at fast idle, the engine will return to
normal idle and remain there as long as the
parking
brake is not applied and/or
transmission is not placed in neutral (n).
The engine will return to fast idle once the
parking brake is applied or neutral (n) selected.
CAUTION
Return the engine to normal idle before shutting
the engine off.
