Lotus Service Notes
LCD Panel
A liquid crystal display (LCD) panel is provided below the instruments in order to display fuel level, coolant
temperature, total mileage and trip functions. The panel is blank until the ignition is switched on.
Fuel Contents Display
An indication of the level fuel in the tank is
displayed in the form of a bar graph at the right
hand top of the LCD panel in the instrument
cluster. When completely full (approximately
43.5 litres (9.6 U.K. gal), the display will show
six black segments. As the fuel level falls,
a white band will extend from the right to
represent the empty portion.
When only a single segment remains,
representing approximately 5 litres, the amber
low fuel tell tale will flash. Refuel at the next
opportunity.
Coolant Temperature Display
The engine coolant temperature will be displayed at the bottom right hand corner of the panel as soon
as the temperature reaches 72°C. The running temperature will fluctuate a certain amount as the operating
conditions change, and during periods of idling or in heavy traffic, the temperature may rise to over 100°C, with
the cooling fans switching on at half speed at approximately 98°C and at full speed at approximately 103°C.
The display will flash at temperatures over 110°C in order to prompt closer monitoring of high temperatures,
but as the pressurised cooling system has a boiling point of over 120°C, only if the temperature approaches
this level need there be any cause for concern. If this should occur, allow the engine to idle for a few minutes
whilst monitoring the temperature, and if it continues to rise, switch off and seek qualified assistance.
After a heavy snowfall, ensure that the radiator cooling outlet grilles in the front body are cleared of snow
before driving the car, or overheating may occur.
Odometer
An odometer (total distance recorder) reading is displayed at the bottom left hand corner of the panel, and
is calibrated in the same units (miles or kilometres) as is the speedometer.
Trip Recorder
A trip recorder is provided at the top left hand corner of the panel, calibrated in the same units as is the
speedometer.
In order to zero the trip display, switch on the ignition, and press for a moment (less than 1 second), the
small button on the steering column shroud between the ignition switch and steering wheel. This dual function
button also controls the panel illumination - see 'Instrument & Switch Illumination'.
Fascia Switches
Lighting functions are controlled by a vertical row of three push button switches mounted in the fascia
outboard of the steering column. Each switch is pressed once to switch on, and pressed a second time to
switch off. A symbol is positioned alongside each switch to indicate its function, and is backlit orange when
the lights are switched on.
Sidelamp Switch
The topmost switch functions with or without ignition, and switches on the sidelamps. A tell tale in the
switch button lights up green to indicate when the circuit is active. Note that the headlamps must be off before
the sidelamps can be switched off.
Headlamp Switch
The centre switch functions with or without ignition, and switches on the headlamps together with the side-
lamps if not already selected by the sidelamps switch. A tell tale in the switch button lights up green to indicate
when the circuit is active. The steering column lever switch (see later) is used to select main beam or dip.
Pressing the switch a second time will switch off the headlamps, but leave on the sidelamps.
