Seat Belt Tell Tale (red)
As a reminder to fasten the seat belts, the seat belt tell tale in the instrument cluster will flash red for about
six seconds following ignition switch on, accompanied, if the driver’s belt is not fastened, by an intermittent
audible tone. Thereafter, if the driver’s belt remains unfastened, the lamp will light continuously, but if vehicle
speed should exceed 15 mph (20 km/h) the lamp will flash, accompanied by a beeping tone for a period of two
minutes, unless curtailed by a speed reduction below 10 mph (15 km/h) before this time.
Airbag Tell Tale (red)
The airbag safety system, including the pre-tensioning seat belts, has a self-diagnostic feature which lights
the red tell tale if a fault is detected. As a bulb check, the tell tale will light for about six seconds following igni-
tion switch on, and then go out, but if the lamp remains lit, or comes on at any other time, a fault in the airbag
system is indicated, which should be rectified without delay by your Lotus dealer.
INSTRUMENTS
Speedometer
This analogue display uses an illuminated pointer to indicate road speed in either mph or km/h dependent
on market. Each time the ignition is switched on, a re-setting routine will be performed with the pointer sweep-
ing to full scale and back to zero. The scale backlighting and pointer will be illuminated whenever the ignition
or sidelamps circuits are active.
Note that a digital speed display in alternative units (mph or km/h) is available in the information panel
menu (see later).
Tachometer
This analogue display uses an illuminated pointer to indicate engine speed in revolutions per minute. The
engine management system graduates the maximum engine speed allowed during the warming up phase, and
once normal running temperature has been reached, limits continuous engine speed to 6,600 rpm (or 7,000
rpm in Sport mode). During maximum acceleration through the lower gears, very short bursts up to 6,800 rpm
are allowed (or 7,200 rpm in Sport mode).
Each time the ignition is switched on, a re-setting routine will be performed with the pointer sweeping
to full scale and back to zero. The scale backlighting and pointer will be illuminated whenever the ignition or
sidelamps circuits are active.
Three red tell tale rings are incorporated into the tachometer face to warn that maximum engine speed is
being approached, but as the rate of rpm increase is potentially greater in the lower gears, the tell tale trigger
points are tailored to accommodate the reaction time available. The tell tales will light in the following left to
right sequence:
- one red light;
- two red lights;
- three rapidly flashing lights with an audible warning.
When exploiting maximum acceleration, gear upshifts should be made immediately the three flashing
lights appear.
NOTICE:
• The use of wide throttle openings and/or high rpm before normal running temperature has been reached
should be avoided. A graduated engine speed limit is imposed on a cold engine to reduce possible dam-
age and wear from a delinquent driving style.
• Do not run the engine continuously at its maximum speed.
• The engine is not protected from overspeeding caused by erroneous or premature downchanging, the
consequences of which could be catastrophic failure not covered by the vehicle warranty.
• Use of maximum rpm and the above tell tale facility should be restricted to occasions when maximum
acceleration is required. Overuse will compromise powertrain service life.
Odometer
A vehicle total distance travelled indicator, in miles or kilometers, dependent on market, is displayed at
the centre top of the instrument panel whenever the ignition key is inserted. See later for the trip distance
function.
