will also disable the engine coolant pump and result in rapid overheating; stop the engine as soon as it is safe to do so, and
summon assistance. If the drive belt is intact and the cooling
system unaffected, it may be possible in favourable daylight conditions, to drive a short distance to a repair facility, but do not, under any circumstances, allow the battery to become
completely discharged by continuing to drive.
Engine Malfunction Indicator Lamp
The engine Malfunction Indicator Lamp (MIL) is provided to
warn the driver that the engine management system has de
-
tected a fault which may result in increased noxious emissions from the exhaust. In order to minimise emissions and potential
engine damage, various operational limitations may automati
-
cally be applied. i) If the MIL lights continuously whilst driving, immediately reduce
speed and adopt a moderate driving style. Seek dealer advice
without delay and avoid all unnecessary journeys.
ii) If the MIL flashes, an engine misfire has been detected which is likely to cause overheat damage to the catalytic converter.
Slow down immediately and be prepared to stop.
- If the MIL then stops flashing, and is lit continuously, proceed with caution and seek dealer advice.
- If the MIL continues to flash, stop the car as soon as it is safe to do so, and switch off the engine. Seek dealer advice.
NOTICE:
Continuing to drive the car with a flashing MIL may
cause overheat damage to the catalytic converter, possible en
-
gine damage, increased emissions, and impaired fuel economy and driveability.
In order to comply with emissions regulations, data regarding
activation of the MIL is recorded in the engine electronic control
-
ler, and may be downloaded by Lotus dealers.
Security/RPM Tell Tale The security tell tale is located at the top of the tachometer
display, and indicates the status of the immobiliser and alarm.
• Tell tale out; engine is mobilised, and the alarm is off.
• Tell tale flashing; engine is immobilised, or alarm is armed
and engine immobilised.
For full details of the car security system, refer to the earlier
section ‘Car Security’.

engine speed is being approached. When exploiting full accel-
eration, gearchange upshifts should be made immediately the
tell tale comes on.
Note that this lamp also functions as a security system tell
tale (see ‘Car Security’). Recalibration of the speedo and tacho needle zero positions
will occur during a 3 second period following ignition switch on,
but if a needle becomes ‘stranded‘ outside of the re-calibration
range, the following procedure should be followed:
With the car stationary;
• Open driver‘s door;
• Press and hold trip reset button on steering column shroud;
• Turn on ignition.
LCD DISPLAY 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 Level Display An indication of the level of 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
10.6 U.S. gall. {40 litres}), the display will show 6 black segments. As the fuel level falls, a white band will extend from the right to represent the empty proportion.

When only a single segment remains, representing approxi-
mately 1.3 U.S. gall. (5 litres), the amber low fuel tell tale will
flash. Refuel at the next opportunity.
NOTICE: Do not allow the tank to run completely dry, as this may damage the catalytic converter and fuel pump. This may
affect the terms of your warranty.
Coolant Temperature Display The engine coolant temperature will be displayed at the bot
-
tom right hand corner of the panel as soon as the temperature reaches 162°F. The running temperature will fluctuate a cer
-
tain amount as the operating conditions change, and during periods of idling or in heavy traffic, the temperature may rise to
over 212°F, with the cooling fans switching on at half speed at
approximately 208°F and at full speed at approximately 217°F.
The temperature display will flash at temperatures over 226°F to prompt closer monitoring by the driver of high temperatures.
The pressurised cooling system has a boiling point of over 248°F.

If the temperature approaches this level then the driver should be concerned. 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.
NOTICE: 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.
Trip Recorder A trip distance recorder is provided at the top left hand corner
of the panel. 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 ahead of the ignition switch.

This dual function button also controls the panel illumination
- see ‘Instrument & Switch Illumination’.

Cooling SystemThe engine cooling system uses a header tank to ensure that
the system remains completely filled, and also to accommodate
expansion of the coolant with increasing engine temperature.
The tank is mounted at the left hand side of the engine bay, and is fitted with a 108 kPa (15 psi) pressure cap to raise the boiling point of the coolant to over 120°C (250°F).
WARNING:
• Do NOT attempt to remove the pressure cap or air bleed plug from the header tank when the engine is warm
as serious scalding could result from boiling water

and/or steam.
• Coolant is hazardous to your health and may be fatal

if swallowed.
• Keep coolant out of reach of children.
• Coolant is hazardous to animals and may be fatal if

swallowed. Clean up spilled coolant and do not leave in
open containers.
The level of coolant in the translucent header tank will rise
as the engine warms up, and fall as it cools down, and under
normal circumstances it should not be necessary to add any
coolant to the system between services. If overfilled, the excess
coolant will be ejected when the engine is warm. If under filled, overheating may result.

Air bleed plugCoolant header tank cap

oh_croft_InD.indd 10620/05/2004 07:59:07ProCarManuals.com

As a precaution, every week when the engine is completely
COLD, and without disturbing the filler cap, check that the level of coolant in the translucent tank is between the ‘FULL’
and ‘LOW’ marks moulded on the front of the tank. If topping
up is required, wait until the coolant has fully cooled before
turning the cap a quarter turn counterclockwise and allowing any remaining pressure to escape. Only then may the cap be
completely unscrewed. In order to maintain protection from freezing damage and
metal corrosion, use only an approved coolant mixture (see below) to top up the tank to the ‘FULL’ mark. Refit the cap, and
turn clockwise until the leg on the cap locates in the slot at the
front of the tank.
NOTICE: If the cap is removed when the engine is warm, the coolant may boil and a small coolant loss may occur. The com
-
pletely cold header tank level should be checked at the first subsequent opportunity.
Cooling Fans
: Two cooling fans are fitted below the radiator in
the air intake duct. The fans are energised at high coolant tem
-
peratures, or when the air conditioning (if fitted) is selected. The
fans will also run if certain types of engine fault are detected, and
may operate during a 20 minute period following ignition switch off to prevent ‘hot soak’ boiling. An electric coolant circulation pump may also be heard running during this period.
WARNING: Keep hands, tools and clothing away from the radiator
cooling fan area, as personal injury could result from the
fans starting up without warning.
At service intervals, the air duct and matrices of the engine
cooling radiator, a.c. condenser and oil coolers, should be
checked externally for clogging by insects, leaves or other debris,
and if necessary, a water jet used to clear the finning. Take care not to damage or distort the delicate finning of the radiator or
the cooling performance will be degraded.
Anti-Freeze/Corrosion Inhibitor It is most important that the correct coolant specification is
used in order to inhibit boiling and protect the engine and heat

exchangers from both frost damage, and metal corrosion. The
Elise is factory filled with a 50% concentration of Havoline XLC
Extended Life Coolant, which contains Organic Acid Technology
(OAT) based corrosion inhibitors to provide long coolant change intervals combined with freedom from environmentally damaging phosphates, silicates and nitrites.
NOTICE: No other type of coolant should be mixed with this
OAT coolant.
Havoline XLC may be identified by its orange colouration, and
by a label around the header tank filler neck. The 50% concen
-
tration provides freezing protection down to - 40°F (- 40°C), and is recommended to be maintained throughout the life of the car.
Stronger concentrations should not be used. In an emergency, if an OAT coolant is not available, the
cooling system should be topped up using water only, but the reduction in freezing protection should be recognised, and the
concentration corrected promptly. In areas where the tap water is extremely hard (exceeding 250 parts per million), distilled, de-ionised or filtered rain water should be used for the water
content of the coolant mix. The effective level of ethylene glycol (anti-freeze) in the sys
-
tem may be measured by your dealer using a hydrometer, but in order to ensure that the required level of corrosion protection is
maintained, the coolant should be renewed every 4 years. For coolant capacity, refer to ‘Recommended Lubricants‘
and ‘Technical Data’.
NOTICE: Using an incorrect coolant mixture may result in ex
-
pensive damage to your engine and/or other car parts caused by overheating, freezing or corrosion effects. This damage would
not be covered by your new car warranty.
Coolant Drain /Refill Procedure The cooling system of the Lotus Elise has been carefully
optimised to allow the required cooling performance using the
minimum volume of coolant. This provides for high cooling sys
-
tem efficiency, with quick engine warm up and interior heating. When refilling the cooling system, it is vital to ensure that
the correct bleeding procedure is followed, and that no air pockets remain. This operation should be entrusted to your
Lotus dealer.

WARNING:Inexper t modifications or additions to the electrical
system could jeopardise safety.
Inertia Switch The safety inertia switch is designed to operate on impact,
typified by car collision, to switch off the fuel pump, and thus
minimise any fire hazard. The central door locking will also be
triggered to unlock the doors. The inertia switch is mounted at the left hand bottom of the
engine bay, on the inboard face of the rear subframe, and is ac
-
cessible from between the coolant header tank and windscreen
washer reservoir. The switch is reset by pressing the rubber
diaphragm button on the top of the unit.
Fuses The main fusebox is located in the front services compartment,
on the passenger side, and is protected by a plastic cover. For
access, remove the passenger side front body access panel,
and unclip the fusebox lid. Twenty two slots are provided for ‘Littel’ type fuses which are
numbered, and coloured according to their amperage rating, and
may be pulled out from their slots using the fuse extractor tool provided on the fusebox lid.
