Operating Manual – Riversimple Rasa Beta
1. Introduction and scope
The purpose of this document is to provide information and instruction to allow safe
operation of Riversimple Rasa Beta Fuel Cell Electric Vehicles (FCEV). This includes:
● An overview of the main safety hazards and general precautions;
● Instructions on how to re-fuel the vehicle from the HRS and using compressed
hydrogen gas;
● Instructions on how to operate the vehicle;
● Details of safety systems.
Instructions within this document are applicable to Beta trial vehicles developed by
Riversimple for use on public roads by the general public. These are assigned VIN numbers
ending with six digits sequentially starting from 000001 up to 000017. Users should be
aware that these vehicles are of a trial nature and should be treated accordingly.
This manual should be read by anyone intending to use or operate Rasa Beta trial vehicles
produced by Riversimple.
2. General safety precautions
Compressed hydrogen gas and a high voltage electrical system are installed on Riversimple
vehicles. If not handled correctly these can present significant safety hazards. To minimise
any risks the following general safety precautions must be followed:
● Only trained technicians are allowed to work on Riversimple vehicles;
● Do not store vehicles in enclosed buildings unless approved by Riversimple;
● Do not attempt to raise or tow the vehicle by any means without consent from
Riversimple;
● High voltage enclosures are clearly marked with the high voltage symbol (Figure 1)
and should never be touched, tampered with or opened except by trained
technicians;
Figure 1: High voltage safety symbol
● High voltage wires and connectors are clearly identifiable as bright orange and
should never be tampered with or adjusted except by trained technicians;
● Areas of the vehicle that contain hydrogen components are clearly marked with the
hydrogen safety symbols (Figure 2) and should be treated with caution appropriate to
handling flammable substances and compressed gases;

Riversimple Operating Manual
Figure 2: Hydrogen, flammability and compressed gas safety symbols
● Hydrogen gas is extremely flammable and burns with an invisible flame. Keep any
potential ignitions sources well away from the vehicle;
● The hydrogen system working pressure on Riversimple vehicles is 35 MPa (5075
psi). Do not attempt to refuel or connect the vehicle hydrogen storage and delivery
system to sources of compressed hydrogen higher than the system working
pressure;
● If there’s any likelihood of damage to hydrogen components, including the storage
tank and supply lines, do not attempt to operate or refuel the vehicle;
● Hydrogen leak detection systems are installed on the vehicle. In case of a leak the
driver’s visual display unit will display a red triangular H2symbol between the dials
(Figure 3). An audible warning will also sound from the driver’s display. In this
circumstance turn-off and leave the vehicle immediately. The hydrogen supply will
have been isolated and the fuel cell will shut-off once any hydrogen in the supply
lines has been depleted;
●

● In case of a serious fault with the high voltage electrical system or its associated
controls the driver’s visual display unit will display a notify stop ‘!’ warning sign
(Figure 4). The audible warning will also sound from the display.

3. Operating the vehicle
Controls for the Riversimple FCEV differ from those of a traditional manual internal
combustion engine car. Being powered by electric motors there is no gearbox and hence no
gear lever or clutch pedal. There are three driving modes, neutral, forward and reverse, as
shown in Figure 5. Accelerator and brake pedals are laid out in a similar way to a normal
automatic car.
Figure 5: Vehicle driving mode controls (infotainment system may differ from that shown)
A Visual Display Unit (VDU) is incorporated into the dashboard, which communicates vehicle
speed, fuel economy, distance travelled and fuel levels to the driver (Figure 6). Approval
compliant warning symbols are included in the display. The VDU will also display a yellow
(Figure 7) or red (Figure 3) warning triangle in the event of a hydrogen system fault. In the
event of a yellow warning please contact Riversimple so the fault can be investigated. In the
5
Riversimple Operating Manual
case of a red warning triangle the vehicle must be stopped and switched off immediately.
Please contact Riversimple without delay.

The following functional safety features have been implemented on beta vehicles:
● When the car is started it will default to the neutral driving mode;
● It is not possible to change driving modes without being stationary and depressing
the brake pedal;
● Notifications will be given to the driver when the vehicle is in active driving mode
(vehicle “car not ready” will disappear from the dash);
Starting the vehicle
1. Ensure handbrake is up
2. Turn ignition key one click clockwise
3. Wait for the dash to power up (up to 15 seconds, but can be < 1 second if the car
was only just switched off)
4. [Optional] Set Driver ID:
a. The driver ID is shown in the lower-right part of the speedometer - repeatedly
pressing the 'i' button on the centre console cycles this I - II - III - IIII to select
the current driver. If the displayed selection is correct, proceed to step 5
otherwise press 'i' until the appropriate driver ID is displayed.

Riversimple Operating Manual
5. The 'car not ready' icon may be displayed above the fuel gauge. As soon as the car
is ready to drive, this is replaced by N (for neutral). Press 'F' (forwards) or 'R'
(reverse) on the centre console to start driving.
6. Disengage the handbrake and drive away. Note that pressing the accelerator pedal
sets the driver Id for this journey.
7. The fuel cell will start up and shut down automatically as needed by the car, with both
the start up and shut down processes
If you don't need to set the driver ID (i.e., it's already correct because the driver is the same
as for the previous journey), the process is:
1. Ensure handbrake is up
2. Turn key 1 click
3. Wait for dash to display 'N'
4. Press 'F' (or 'R'), handbrake down, drive off.
Stopping the vehicle
1. Bring the car safely to a stop using the brake pedal;
2. Engage the handbrake;
3. Turn the ignition keyone click in the anti-clockwise direction to the ‘off’ position.
In case of an accident
If the vehicle is involved in a collision, follow this procedure:
1. Turn off the car as soon as it is safe to do so by turning the ignition key one click in
the anti-clockwise direction to the ‘off’ position;
2. Move well clear of the vehicle;
3. Notify any assistance or emergency responders that it is a hydrogen fuelled vehicle
with a high voltage electrical system;
4. Do not attempt to restart or refuel the vehicle without consulting a trained technician;
5. If the vehicle needs to be moved use a flat-bed lorry; do not tow the vehicle.
Ancillary Equipment
The vehicle is fitted with front and rear demist units operated from the switches as shown in
Figure 5. These units will automatically switch off
The info switch can be used to toggle between outside temp, digital clock and trip. To reset
the trip, while in trip mode hold the button down until it resets, then release.
The vehicle is fitted with an infotainment system comprising DAB radio and Bluetooth
connectivity for audio and phone. Refer to separate instruction manual for use. The user is
responsible for compliance with applicable laws concerning the use of the phone while
driving.
A 5v USB power-only connection is incorporated into the heater control binnacle, for
charging mobile phones(see Figure 11 for location).
