Ignition Switch - PREVOST X3-45 Commuter 2020 Operating Manual

6-2 Starting and Stopping Procedures

IGNITION SWITCH

The vehicle is equipped with a starting aid system
which allows cranking the engine even if the
batteries are depleted. Reserve power is stored
in a super capacitor located next to the
wheelchair lift platform.
An ignition switch (ON and OFF positions) and an
independent ignition button (momentary switch)
are used instead of an ignition key. Both are
located side to side on the lower left side of the
dashboard. To start the vehicle, turn the ignition
switch to the ON position and then push the start
button.

NOTE
The vehicle is equipped with a "wake- up"
function that will maintain power to important
circuits for a period of 15 minutes when

Beside accessories directly connected to the
battery, the following electrical circuits are
activated when the switch is in the ON position:
transmission, engine and accessories, ABS
system, wipers, dashboard cluster gauges and
buzzers, temperature display, radio, Wi- Fi,
cameras and information systems, air horn, air
dryer as well as the interior and exterior lighting
(excluding headlights).
Do not leave the key in this position unless the
engine is running.
NOTE
When the hazard flashers are activated, the
vehicle electrical circuit switches to the ON
position even if the ignition switch is at the OFF
position.
NOTE
To prevent discharge of the batteries when the
engine in not running, some functions are
automatically switched off if the battery SOC
(State Of Charge) falls below 65% for more
than 30 seconds. A pictogram (alternator) and
a message will appear in the DID while this
protection mode is active. Set the ignition key to
the OFF position and then turn the ignition key
to the ON position to reactivate the functions for
a period of 30 seconds before they switch off
again. If a prolonged use of the functions with
the engine not running is necessary, connect
the battery to a charger.
START BUTTON – With the ignition switch set at
the ON position, use this momentary switch to
crank and start the engine.
NOTE
If the engine was shut down by the automatic
idle shutdown timer (after 15 minutes of idling)
the ignition switch must be switched to the OFF
position 10 seconds prior to
