HEATING, VENTILATION & AIR CONDITIONINGThe small size of the Elise together with the method of
construction and emphasis on lightweight, have resulted in heating and a.c. sytems which perform well under non-extreme
climatic conditions. In extreme temperatures and humidity the operational limits of the systems may be reached before the
desired temperature, or rate of temperature change inside the
car is achieved. The heating and ventilation controls comprise three rotary
switches to regulate; heater temperature, fan speed and air dis
-
tribution. Push button switches are provided for air conditioning and air re-circulation.
Air Conditioning The left hand push button selects air conditioning, but the
following conditions must first be met before the system will
operate:
• The engine must be running;
• A fan speed must be selected;
• Ambient temperature must be above 3°C.
With a fully cold temperature setting, refrigerated air will be
supplied. For dehumidified warm air, select air conditioning in
conjunction with a warm temperature setting. The tell tale in the switch button will light up blue when the
circuit is active. Note that the a.c. will default to ‘off’ when the ignition is turned off.

INTERIOR CLIMATE CONTROLS

oh_croft_InD.indd 6120/05/2004 07:58:56ProCarManuals.com

Air Re- circulation The air supply for the interior climate system is normally drawn
from both the car interior and from the fresh air intake duct ahead
of the engine cooling radiator. When the re-circulation button is pressed, the fresh air intake port is closed down to provide 90%
re-circulation air supply to the cabin interior. The re-circulation
facility should be used when maximum refrigeration is desired.
The tell tale in the switch button will light up blue when the
circuit is active.
Heater Temperature With the left hand rotary control turned fully counterclockwise,
no heating is provided. If cooled air is required, use this tem
-
perature position in conjunction with air conditioning. Turning the control progressively clock wise provides in
-
creasing levels of heat until at the fully clockwise position, maximum heat is supplied.
Fan Speed The centre rotary switch provides three fan speeds to boost air
circulation. Turned fully counterclockwise, the fan is off; Turning
the switch progressively clockwise operates the blower fan at increasing speed in three steps. Note that the fan operates only with the ignition switched on.

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

Auxiliary Drive BeltA single, multi-rib type auxiliary belt is used to transmit drive
from the crankshaft to the alternator, water pump, and (if fitted)
air conditioning compressor. The belt is automatically tensioned,
and requires no periodic maintenance other than a visual check of its condition. If the belt exhibits any evidence of physical dam
-
age, cracking, fraying, perishing, abrasion or contamination, it
should be renewed. In the case of contamination, the cause
must be identified and rectified, and each of the pulleys must be thoroughly degreased before the new belt is fitted. It is recommended that auxiliary belt replacement be en
-
trusted to your Lotus dealer.
Sparking Plugs The Elise uses a direct ignition system with an individual
high tension coil mounted atop each of the four spark plugs and protected by a plastic cover, screw fixed to the engine.
WARNING: The voltages produced with this ignition system can
cause serious and potentially fatal injur y. Never touch
any ignition components when the engine is running or being cranked.
The spark plugs should be renewed in accordance with the
Maintenance Schedule, with the gaps set to 0.043 in. (1.1 mm).
This operation should be entrusted to your Lotus dealer.
