2005 LOTUS ELISE air

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.

Air DistributionThe right hand rotary control determines the distribution of
air flow to the various outlet vents. A few moments should be
allowed for the flaps to operate following a new selection:
Face Level: Turned fully counterclockwise, all airflow is directed to the four
face level vents, each of which may be manipulated to adjust
volume and direction.

Footwell:
As the control is turned clockwise from the face level vents
symbol towards the footwell symbol, an increasing proportion
of air flow is directed towards the footwell vents.

Demist:
As the control is turned clockwise from the footwell symbol
to the windscreen symbol, more air flow is directed to the wind
-
screen vents. Select a warm temperature setting and a suitable
fan speed.
Full Defrost Per formance For maximum defrost per formance, turn the distribution
knob fully clockwise and select maximum temperature and fan
speed.For optimum demisting in ambient temperatures above
38°F (+3°C), switching on the a.c. will help de-humidify the air directed to the screen.
Ventilation Shut-Off To close off the ventilation, which you may want to do in heavy
traffic to reduce fumes coming into the car, select re-circulation,
turn off the fan, turn the distribution control fully counterclock
-
wise to the face level vent position, and manually shut off each of the face level vents.
Engine Bay Ventilation The engine bay is ventilated via intake ducts in the body sides
and engine undertray, with outlet grilles provided in the engine
cover and rear valance.

integral self diagnostics have switched out the anti-lock function.
See ‘ABS tell tale lamp’.
WARNING:
• The increased control that ABS provides should not induce you to take more risks with your safety. ABS will
not prevent a skid caused by abrupt steering movements,
or attempting to corner too quickly.
• Always maintain a safe following distance from other cars relative to the road surface and weather conditions.
Obey all traffic laws.
• Risk of accidents due to inappropriate speed cannot be reduced even by ABS. The driver is responsible for the
judgement of safe speed.
• The control unit of the ABS is set for standard tire size. If non-standard Tires are fitted, the control unit may mis-
interpret the speed of the car, because of the variant data
it receives from the wheel speed sensors. Fitting non standard tires would seriously affect the performance of
your ABS.
• The amber ABS tell tale in the instrument panel should light for about 4 seconds following ignition switch on, and
then go out. If the lamp remains lit, or comes on whilst driving, a fault in the anti-lock brake system is indicated.
The base brake system will continue to operate normally,
but without ABS. The car can be driven but should be
checked and repaired at the earliest opportunity.
• Activation of the ABS will vary according to the level of grip available at the Tires. On dry surfaces, activation
will occur only with a high pedal pressure. On slippery
surfaces, only a low pressure will be needed.
• On loose or uneven surfaces, such as gravel or snow, a car with ABS may need a longer stopping distance. Allow
a greater distance between cars in these conditions.

5. Unhook the two roof stays and pack in the roof bag. Stow the
bag in the rear luggage compartment.
NOTICE: If the roof is not fully dry, it should be stowed for no longer than 1 or 2 days before unrolling or refitting and allowing
to air dry completely. Prolonged stowage of a wet or damp roof
will promote rotting of the fabric.
HARD TOP ROOF
NOTICE:
• The hard top roof has been designed to provide a seasonal,
rather than single trip option. Some owners may prefer to
entrust the fitting and removal of the hard top roof to their
dealer.
• When stowing the roof off the car, care should be taken to
avoid damage to the roof corners; e.g. use a suitable soft
floor covering on which to stand the roof. Note that there is
no provision for on-board hard top roof stowage.
• Fitment or removal of the hardtop is made considerably easier
with the assistance of a second person.
• Use only the ‘Torx’ tool supplied in the car tool kit (in the
battery cover rear pocket), to tighten or release the roof

fixing screws.
• The hardtop roof fixings are tethered to the roof panel to guard
against their loss.
WARNING:
Take care to avoid trapping hands or fingers when fitting
or removing the hard top.

SERVICING AND MAINTENANCEBODYCARE
Body Features Lotus are among the world leaders in the field of automotive
composite moulding design and manufacturing techniques.
Composite materials have major advantages for specialist car bodies, and these brief notes introduce some features of the
construction and service properties of automotive composite bodies. The manufacturing process enables the thickness of com
-
posite mouldings to be varied in order to provide ef ficient structures of high strength and low weight. Composites will not
corrode, so the strength of composite components is retained regardless of age, unless physical damage is sustained. On
the Elise, the body construction utilises several mouldings to
form a single unit for the whole of the nose and front wings, and
a second unit for the whole of the rear body aft of the doors.
These two moulded assemblies are fixed using threaded fasten
-
ers to permit easy removal for access to chassis or powertrain
components, or to allow simple and economic accident repair.
Other composite mouldings include the door shells, sills, front access panels, windscreen frame and rear bulkhead, some panels being bonded to the aluminium alloy chassis with an
elastomeric adhesive.
Several different processes are used to manufacture the
various panels depending on the functional requirements, with the main outer panels using an injection compression mould
-
ing technique which eliminates the ‘gelcoat’ used on the outer
surface of conventionally manufactured composite panels. This
process provides considerably increased resistance to surface
damage from minor knocks, where a conventional composite panel would suffer cracking of the gel coat, or a steel panel be
-
come dented. If severe damage is caused to a composite panel
where the underlying structure is broken, repairs may take the
form of panel replacement, or of panel repair using techniques
where new composite material is integrated with the old to result in undiminished panel strength.

Soft Top Roof
1. Careful vacuuming of the soft top before washing may be
helpful in removing excess dust and other foreign particles.
2. Wash in partial shade rather than strong sunlight.
3. Using only clean lukewarm water and a sponge (a chamois or
cloth will leave lint, and a brush may abrade the threads), wash
the entire soft top uniformly. Do NOT use a detergent, which may
affect the waterproofing properties of the material.
4. Rinse the whole car to prevent streaking on the paintwork. 5. Remove surface water with a sponge and allow to air dry in direct sunlight. Ensure that the roof is fully dry before stow
-
ing, as prolonged stowage of a wet or damp roof will promote
rotting of the fabric.
Keeping the soft top clean by regular washing will enhance
the life and maintain the appearance of the roof, and facilitate subsequent cleaning. The use of stronger cleansers should be left to professionals experienced in handling this type of fabric
as discoloration and degradation of the material may result.
The application of wax finishes, dressings or preservatives may cause stains, and should be avoided. Your dealer will be able to advise on current Lotus approved soft top care products.
Windscreen Cleaning When washing the windscreen, take care to lift the wiper
blade only a small distance from the glass in order not to dam
-
age the wiper arm mechanism. Wash the wiper blade with

clean water.
Alloy Road Wheels It is recommended that the aluminium alloy road wheels
are washed with the same preparation as is used to wash the bodywork. Use a brush having only nylon bristles. During the
winter months, particularly when salt has been used on the
roads for the dispersal of snow and ice, remove all the wheels,
and wash thoroughly to remove all accumulated road filth from
the wheels and Tires. Be aware that on cars fitted with optional clear anodised
forged alloy wheels (with 7 twin-spokes), the anodised surface
finish may be attacked by some proprietary wheel cleaning products. Wash only using hot soapy water or car bodywork
shampoo. Advise tire fitting companies accordingly.
