Seat Belt Tell Tale
The red seat belt tell tale is provided as a reminder that both
driver and passenger should always wear the seat belts, no
matter how short the journey. The lamp will flash until the driv
-
er’s seat belt is fastened, accompanied for the first 8 seconds by a buzzer.
Brake Tell Tale
This tell tale will glow red with the ignition switched on
whenever the parking brake is applied. Driving the car with the brake not fully released will cause overheat damage to the rear
brakes. Each time the parking brake is released, check that the
tell tale is extinguished. With the parking brake released, if the tell tale should light
at any time after the six second check period, stop the car im
-
mediately, as the circuit has detected a dangerously low level of brake fluid in the master cylinder reservoir, possibly caused
by a hydraulic leak in one of the separate front or rear brake
circuits. In the event of a leak there is a danger that air may enter the hydraulic system and cause spongy operation and
extended pedal travel. The divided brake circuit should ensure
that emergency braking remains, but the car should not be driven until the fault has been identified and rectified.
WARNING: If the tell tale remains lit when the parking brake has been
released, the footbrake may not be working properly. Stop
the car immediately it is safe to do so, and do not continue until the fault has been rectified. Continuing to drive could cause a crash and result in death or serious injury.
Oil Pressure Tell Tale
This red tell tale warns of low engine oil pressure. The lamp
will be lit whenever the ignition is on and the engine is stopped, but should go out as soon as the engine is started. If the lamp
fails to go out after engine start up, or comes on when the engine is running, stop the engine immediately and do not restart until
the cause has been investigated and rectified.

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.

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

Storing Your EliseIf you intend to store your Elise for a prolonged period, con
-
sult your Lotus dealer who will be pleased to advise you. We recommend that the car is stored inside a secure garage. The
following guidelines are provided for your information:
• Ensure the engine oil and filter, coolant and brake fluid have recently been renewed. The a.c. system should be in good
working order and fully charged.
• Thoroughly clean the inside and outside of the car, including the engine compartment. If necessary, use a ‘jet’ washer to remove dirt and salt deposits from the underside, but do not
use around bearings, hydraulic components, painted surfaces or the soft top roof. Allow to dry completely.
• Chock the road wheels, leave off the parking brake, and engage reverse gear.
• Increase the tire pressures to 60 psi (4 bar). If possible, move the car slightly every month to help avoid flat spots on the
Tires.
• Either leave the battery in the car and connect a battery management (conditioner) type of charger, or remove the battery and trickle charge every two months. Note that with
the battery disconnected or removed, the alarm system is
de-activated.
• Unless the garage is equipped with a de-humidifier, the use of drying agents (Silica-Gel) is recommended in cars with
leather upholstery and in conditions of high humidity.
• The use of unapproved car covers may have a detrimental effect on the car’s paint finish and such damage will not be
covered by your car’s warranty.
In general, the Elise will be kept in best operating condition
by regular use.
