NOTICE: DO NOT push or tow start the car; or turn off the igni-
tion at engine speeds above idle; or run the fuel tank dry: Any of these actions may damage the catalytic converter.
Before driving the car:
• Check tires for damage, wear and proper inflation.
Under-infla-
tion causes increased rolling resistance and uses more fuel.

(Please refer to the section in this handbook on tires, page 115).
• Check all windows, mirrors and lights are clear and unob
-
structed and all lights are correctly working.
• Check that the engine cover and front body access panels
are correctly latched;
• Adjust the seat and mirrors, and familiarise yourself with

the controls.
• Check all instruments and warning lamps (‘tell tales’) are reading correctly.
• Ensure that both driver and passenger are properly restrained
by their seat belts.
Care of the Environment By virtue of its light weight, simple content, constructional
process and fuel efficiency, the Elise has a low environmental im
-
pact compared with many road cars. All drivers should, however,
be aware of the effect of motor car exhaust emissions on the
environment and drive in a way which minimises pollution by:
• Anticipating traffic flow to avoid needless acceleration

and braking.
• Using the highest suitable gear.
• Switching off rather than idling for long periods.
• Driving off as soon as it is safe to do so; it is not necessary or beneficial to the engine to allow extended idling from cold.
• Having the car serviced regularly as a poorly maintained car will use more fuel; have any engine faults attended to imme
-
diately.
• Considering the need to use the car for very short journeys.
The emissions produced by an engine are many times greater
when cold than when warm.
Safety Information

Note that the tell tale also functions as a high engine speed
(rpm) warning - see ‘Tachometer’.
NOTICE: The car is not fitted with a low pressure tell tale. You should check the tire condition and pressure regularly. See
section in the handbook on tires which specifies tire care and pressures.

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.

efforts are likely to reduce during the break-in process.After 600 miles (1,000 km) have been covered, full throttle
and/or maximum rpm may be used for short periods, but not
until the first ‘After Sales’ service has been carried out should
full car performance be exploited. Note that various operating parameters are continuously
monitored and recorded in the engine electronic controller. This
data may be downloaded by Lotus dealers on demand to assist
fault diagnosis and identify vehicle misuse.
Tires:
New tires also require a short ‘break-in’ period before
providing optimum grip.
Engine Special Features The engine of the Elise is designated V VTL-i for ‘Variable
Valve Timing and Lift - intelligent’. Using microprocessor control, the inlet camshaft timing is advanced or retarded according to
immediate operating conditions, and the lift of both inlet and
exhaust valves is increased at high engine speed. This technol
-
ogy is used to provide high power output whilst retaining good
low speed response.

EMERGENCY RELEASE HANDLE (viewed from lid underside)
WARNING:The maximum weight of goods which may be carried in the
trunk is 110 lb (50 kg). Exceeding this limit can overload the
Tires and affect the handling of the car, and result in a crash in which you or others could be killed or seriously injured.
Refer also to the ‘Tires’ section in this handbook.
Child Entrapment If a child should become trapped in the rear luggage com
-
partment, an emergency internal release handle is provided to facilitate their escape.
To release the latch, pull the fluorescent handle on the un
-
derside of the lid. Parents should decide if their children should be shown how
to use this feature.

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.

TIRES AND WHEELS
TiresGlossary of Terms:Recommended inflation pressure: The cold tire inflation pressure which is recommended for this car and is speci
-
fied in the ‘Technical Data’ section of this handbook.
Cold tire inflation pressure: All tires must be cold, meaning
that the car has been stationary for a minimum of 3 hours, or has been driven less than 1 mile. Adjust pressures only
in ambient conditions.
Maximum inflation pressure: The maximum inflation pres
-
sure to which the tire should be subjected. For the Elise,
use only the recommended inflation pressure.
Lotus engineers have worked with tire manufacturers
to produce tire specifications for the Elise which optimise performance on both road and track. To ensure that any
replacement tires are to the correct Lotus specification,
always refer to your Lotus dealer, who will have the latest recommendations.
WARNING: In order to achieve the optimum handling char
-
acteristics, the wheel and tire sizes on the Elise are different front and rear. This means that interchanging
of wheels and tires between axles is not permissible.
Failure to adhere to this requirement will adversely affect the handling of the car and may result in an
accident in which you or others could be killed or seriously injured,
The tires should be regularly inspected for signs of cuts,
abrasions or other damage, and for any uneven tread
wear patterns. Uneven treadwear may indicate that the suspension geometry or dampers require attention from
your dealer.

NOTICE:
• On cars used on a race track or in a competitive manner,
special vigilance is required due to the severity of tire operating conditions, with careful inspections carried
out between sessions.
• Take care when parking to avoid tire contact with high
or sharp edged kerbs. Such mistreatment can cause
internal damage to the tire structure and this may not be readily apparent. The wheel rims may also be distorted or damaged by careless parking, and result in wheel
imbalance or loss of tire pressure. Similar damage may also be caused by potholes, rocks or other highway
debris.
WARNING:
• Damage to wheels and tires may cause an accident in which you or others may be killed or seriously
injured. If the wheels or tires have been damaged,
have them replaced.
• Safety considerations should always be paramount when assessing tire condition and serviceability, and the tires replaced if any doubt exists, or if the
legal tread depth limits are approached.
• Poorly maintained and improperly used tires are dangerous.
• Overloading your tires can cause overheating as a result of too much friction. You could have a blow
out and a serious accident in which you could be killed or seriously injured. See ‘Tire Placard La
-
bel’.
• Underinflated tires pose the same danger as over loaded tires. The resulting accident could cause serious injury, or death. Check all tires frequently
and maintain at the recommended pressure. Tire
pressures should be checked only when the tires
are cold.
• Overinflated tires are more likely to be cut, punc- tured or broken by a sudden impact - such as hitting a pothole. Keep tires at the recommended pressure.
• Installing improper tires on your car can affect handling and stability. This can cause a crash
in which you can be killed or seriously injured.

Tires & Wheels

oh_croft_InD.indd 11620/05/2004 07:59:09ProCarManuals.com

Always use the size and type of tires recommended
in this handbook.
• Using incorrect tires or tires which are excessively worn or improperly inflated can cause a crash in
which you can be killed or seriously injured.
• Please note your car is not fitted with a low tire pressure tell tale lamp so it is especially important
that you regularly check the tire pressures.
When driving on wet roads, surface water is squeezed
out from between the tire and road. However excessive
speed or water depth can overwhelm the water clearing capability of the tread and lead to a condition called 'aq
-
uaplaning' or ‘hydroplaning’, where the tire rides on a film of water and provides little or no grip on the road surface,
leading to a loss of control. This condition is more likely
to occur with worn tires having little depth of tread, or with incorrect tire pressures. Drivers should keep a vigilant check on tire wear and condition, and moderate their
speed in adverse weather conditions.
Tire Care Wear indicators are moulded into the bottom of the
tread grooves at intervals around the tire, indicated by small pointers on the outer tread blocks. The tires should
be replaced before being worn to this minimum legal
tread depth. The cold tire pressures should be checked every week,
or every 1,000 miles (1,700 km), whichever is the sooner,
and corrections made as necessary. See ‘Technical Data’
at the back of the handbook for tire pressures. For track
use, tire condition and pressures should be checked be
-
fore each run. Under-inflation will cause excessive wear, rapid deterioration of the tire sidewalls and heavy steering,
whereas over-inflation results in a hard ride and increased susceptibility to tire damage. Both conditions will cause a degradation in the handling qualities. It is important that the tire pressures are adjusted only
when the Tires are cold (when the car has been standing for a minimum of 3 hours, or driven less than 1 mile), as the pressures may increase by 0.3 - 0.5 bar (4 - 8 lb/in²)
when the Tires are warmed to normal running temperature.
