ELECTRONIC STABILITY CONTROL (OPTION)

The Electronic Stability Control (ESC) is a feature
for ABS-equipped vehicles that reduces the risk
of rollovers and loss of control. The ESC system
features include the RSP Roll Stability Program
and Yaw Control.
The RSP system counteracts the tendency of a
vehicle to tip over while changing direction
(typically, while turning).
To reduce the risk of rollover, the RSP system
detects potential rollover conditions and slows
the vehicle both by reducing engine throttle (and
hence, engine torque) and by applying service
brakes as needed at the appropriate wheels.
WARNING
During an RSP system intervention, the vehicle
automatically decelerates. The RSP system can
slow the vehicle with or without you applying the
brake pedal, and even when you are applying the
throttle.
During an RSP system intervention, you can
always use your service brake pedal to increase
the braking pressure that will be applied.
However, if you were to apply less braking
pressure than needed or even if you release the
brake pedal entirely during an intervention, the
RSP system will continue to apply the necessary
amount of braking pressure automatically to the
appropriate wheels to mitigate a potential
rollover.
Yaw Control is a feature that reduces the risk of
loss of control. If a vehicle's tires start to slide
during a turn, Yaw Control counteracts the
tendency of that vehicle to spin (or yaw), thereby
reducing the risk of loss of control. Many factors,
including road conditions, load distribution and
driving behavior, can
development of a spin.
WARNING
In the case where a vehicle equipped with the
ESC system pulls a trailer, the latter must be
equipped with ABS.
WARNING
Even with ESC- equipped vehicles, the driver
remains responsible for ensuring vehicle stability
during operation.

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 L.H. DASHBOARD PANEL
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 or when the wheel chair lift (WCL) is in
function.
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
