Introduction
The purpose of this operation guide is
to provide drivers with information to
help them to operate their vehicles
safely and efficiently. It is
recommended that it is kept with the
vehicle.
Care and attention given at the right
time will ensure efficient and
satisfactory performance. Periodic
attention is necessary, and should help
to avoid breakdowns. Never run the
vehicle in a doubtful condition, always
report back to the garage for inspection
and attention.
Vehicles manufactured by Alexander
Dennis, when delivered, comply with all
current Department of Transport
Regulations and Codes of Practice
appertaining.
Whilst every effort is made to ensure
the information given in this handbook
is correct at the time of going to print,
the Alexander Dennis policy is one of
continuous improvement and the right
to change specifications and
equipment without notice is reserved.
In all communications quote the
relevant V.I.N. and engine number.
This will ensure prompt attention.
Gross Vehicle Weight and Axle
loadings are based upon the maximum
seating capacity of the vehicle, as
delivered, (including Driver).

It is recommended that this
handbook is kept with the
vehicle.
This handbook is based on
the Trident 2 axle chassis with
Euro 3 engine and original
equipment fitted at the
factory. You should therefore
bear in mind that the
bodybuilder may have made
changes to the vehicle.
For this reason, you may find
illustrations and/or certain
parts of the text in this
handbook which do not
correspond exactly to the
particular situation on your
own vehicle.

General Description
The Alexander Dennis two axle Trident
is, powered by a 6 cylinder turbo
charged diesel engine driving a portal
rear axle through a three or five speed
automatic transmission.
The air operated braking system is
powered by an engine-driven
compressor supplying five reservoirs
through an air dryer which also
regulates pressure.
Service One and Service Two
reservoirs each supply a separate
system for the brakes on the front and
rear drive axles. The park reservoir
supplies the spring-applied, air
released brakes on the Drive axle. The
Auxiliary reservoirs supply the air
suspension system and body services
such as the doors.
The hydraulic system is powered by an
engine driven tandem pump which
supplies the steering box and cooling
fan.
The front and drive axle suspension are
multilink with anti-roll bars and
supported by air springs and hydraulic
dampers.
The 24 volt electrical system is
powered by an engine driven alternator
and two batteries. The system supplies
the lighting, warning and indicating
systems.
An electronically - controlled air system
is installed which allows a kneeling
system to operate. The kneeling
system allows the front suspension air
springs to be deflated, to lower the
passenger entrance of the vehicle
almost to kerb level then re-inflate the
suspension springs to raise it again
before moving off.

17
Warning Lights
Warning Light Function
The warning lamp informs the driver of
the system condition and to transmit
blink codes for system and diagnostic
information.
If the warning lamp fails to go out when
the vehicle is driven off, or if it comes
on shortly after drive off, this is an
indication that the ABS system is either
disabled or partially disabled due to a
fault. If the system is disabled the driver
still has full use of the conventional
braking system. When the warning
lamp lights up this indicates increased
danger of wheel lock-up. The driver
should exercise caution when braking
to avoid loss of control due to wheel
skid.
The warning lamp is switched on (bulb
check) after “ignition on”. If a wheel
speed sensor fault was not stored in
the fault memory before the last
“ignition off”, the warning lamp will be
switched off about 2 seconds after
“ignition on”, provided the static system
test was successfully completed. The
warning lamp the remains switched off
when the dynamic system test has
successfully concluded
If a wheel speed sensor fault was
stored before the last “ignition off”, the
warning lamp remains on until the
static and dynamic system test has
successfully been completed - a stored
fault.
• The driver is responsible for
taking note of the warning
lamp. If the warning lamp fails
to light up immediately after
“ignition on” this indicates that
the lamp bulb is defective. It
MUST be replaced without
delay.
• When a fault occurs, it is
essential that the ABS is
checked immediately in an
authorised workshop in order to
repair the fault and return the
system to normal operation.
Failure to do so may result in
unforeseen consequences.
Safety Instruction
While the ABS increases the vehicle
safety, it is not able to overcome natural
physical laws. ABS can only optimise
the utilisation of the available traction
between the tyres and the road. ABS is
not able to compensate for poor
driving, to avoid the consequences of
driving too close to the vehicle in front,
and/or driving into a bend with
excessive speed.
