normal running temperature has been reached. Ver y shor t bursts up to 8500 rpm are allowed during maximum acceleration
through the lower gears. A 6000 rpm limit is imposed on a cold engine in order to
reduce possible damage from a harsh driving style.
NOTICE:
• The use of wide throttle openings and/or high rpm before
normal running temperature has been reached will result in
premature wear and should be avoided.
• Do not run the engine continuously at its maximum speed,
or allow overspeeding to occur on the overrun by downshift
-
ing prematurely, as the high engine loads imposed could

result in catastrophic failure.

FootbrakeVentilated disc brakes are fitted to all four wheels of the
Elise. These are operated by separate front and rear hydraulic
circuits, supplied from a tandem master cylinder with vacuum
servo. Anti-lock control is provided by a microprocessor based

electro-hydraulic unit, integrated into the base braking system. The braking system is designed to provide good pedal feed
-
back, with efficient disc cooling to inhibit brake fade. With a
new car, or new brake system components, maximum braking
efficiency will be achieved if, for the first few hundred miles, needless heavy braking is avoided. Allow the brake pads and discs to ‘bed in’ fully before using the brakes to their full potential.
Pedal effort will reduce as the brakes are bedded in, and as they
are warmed from cold to normal working temperature. Note that
the hard grade pad material may give rise to a certain amount of brake noise under some conditions; such noise is not harmful
and does not affect the life or efficiency of the brakes.
WARNING:
• After driving through a ford, or a flooded road, some loss of braking response may be experienced until the brakes
have dried out. As soon as it is safe to do so after such an encounter, apply the brakes until normal operation
is restored. Failure to do so may result in an accident in
which you or others may be killed or seriously injured.
• The brake assistance servo uses vacuum supplied from the engine intake plenum, such that assistance is avail
-
able only when the engine is running. Never coast down
-
hill with the engine stopped. If this situation accidently arises, avoid repeated application of the brakes, or the
stored vacuum supply will be rapidly used up. Greater
pedal pressures will be required. This may adversely affect performance of the brakes which may result in an
accident in which you or others may be killed or seriously
injured.
Anti-lock Brake System The Anti-lock Brake System (ABS) is used to optimise brake
performance in extreme conditions and reduce the potential
for any wheel to lock up. Under most conditions, the maximum braking force is provided by a wheel which is rotating at about
90% of road speed. Apart from the likelihood of increasing the
Driving Controls

oh_croft_InD.indd 6720/05/2004 07:58:57ProCarManuals.com

stopping distance, a locked wheel provides little or no steering
force, such that with both front wheels locked, movement of the steering wheel has no effect on car direction. With the anti-lock
system, even panic braking results in controlled deceleration and the retention of steering response. ABS is especially ad
-
vantageous when braking on slippery road surfaces and in bad driving conditions, but it is important to realise that the ABS
cannot increase the friction level at the road surface, but can only make optimum use of the grip available.
WARNING: When driving in adverse weather, or on poor road sur
-
faces, always be alert to the possibility of slippery condi
-
tions and make the necessary allowance for increased stop
-
ping distances. Failure to do so may result in an accident in which you or others may be killed or seriously injured.
Normal braking, controlled by the pressure applied to the
brake pedal, occurs when the road conditions allow for decel
-
eration to be achieved without danger of wheel lock. The relative
speeds of the four wheels are continuously monitored by the
ABS when the brakes are applied, and if one or more wheels begin to lock, the brake pressure to that wheel(s) is modulated
by the ABS to help keep the wheel rotating and provide the
maximum controlled braking force. The wheels may appear
to lock momentarily as the wheel speed rapidly changes, and some tire noise (intermittent screeching) may be heard which is normal and will vary with road and tire conditions. Note that the
ABS does not function at speeds below 5 mph (7 km/h). When the ABS is activated, the driver is will feel a ‘pulsing’
sensation at the brake pedal as the fluid pressure is modulated, and also by audible clicking sounds. These signals indicate to
the driver that maximum braking is occuring, and that driving style should be modified to suit the conditions.
The minimum stopping distance is achieved by applying the
brakes firmly and steadily, and allowing the ABS to modulate
hydraulic pressure. The driver should not attempt to emulate
this process by ‘pumping’ the brake pedal, as modulation at the pedal will treat all four wheels similarly, rather than the individual
wheel control allowed by the electronics. An ABS tell tale lamp in the instrument panel is provided
to warn of any problems in the system and to indicate that the

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.

NOTICE: The Elise is not equipped with conventional separate shock absorbing bumpers, so extra care should be taken when parking to guard against body damage. The Lotus Elise does
not offer the same kind and degree of impact resistance or
energy absorption afforded by conventional U.S. bumper sys
-
tems. Care is also required, due to the low ground clearance, to guard against car underside damage caused by ramps, kerbs
and road humps.
Paint Care The acr ylic enamel finish of the Lotus Elise is extremely
resistant to all normal forms of atmospheric attack. Following
the simple maintenance procedure summarised below will help retain the gloss, colour and protective properties of the paint
throughout the life of the car. However, car finishes are not im
-
mune to damage and amongst the more common causes of deterioration are:
- Atmospheric contaminants; dust, soot, ash, and acidic or
alkaline aerosol mist can chemically attack paint.
- Abrasion; blowing sand and dust, or a dirty washing cloth.
- Tree sap and insect fluids; can form a water-insoluble polymer
that adheres to the paint.
- Bird excrement; highly acidic or alkaline, they can chemically etch the paint. Wash off immediately.
- Leaves; contain tannic acid which can stain light finishes.
- Impact damage; granite chippings thrown up from poor or recently dressed road surfaces can subject the body to severe
localised impact, and result in paint chips, especially around
the vulnerable frontal panels. Do not follow other cars too closely in such circumstances. For optimum paintwork pro
-
tection, Lotus recommends the use of a self adhesive film kit
which your dealer will be pleased to supply and/or fit.
- Moisture entrapment; Long term use of a non-breathable car cover can trap moisture and/or induce condensation and promote water penetration of the paint film.
Ventilation Water lying on the paint surface for a lengthy period will even
-
tually penetrate the paint film. Although the effects will not be
visible immediately, a deterioration in the protective properties
of the paint film will ultimately result.

DIPSTICK
Engine Oil Level Check
WARNING:
• Engine oil is hazardous to your health and may be fatal
if swallowed.
• Use protective gloves to avoid contact with skin as far as possible and wash thoroughly after any contact.
The engine oil level should be checked regularly, such as
every two or three fuel stops, and the oil level maintained near
the top mark on the dipstick. It is especially important to keep a check on the oil level during the car’s first 1,000 miles (1,600
km), as both the fuel and oil consumption will be prone to some
variance until the engine components have bedded in. The best time to check the level is when the oil is warm, such
as during a fuel stop. Ensure that the car is parked on a level
surface and that a few minutes have elapsed since stopping
the engine to allow oil to drain back into the sump. If the engine is stopped before reaching normal running temperature, the oil
will not drain back so readily, and the dipstick will display an artificially low reading.
Dipstick: The dipstick is identifiable by its yellow loop handle,
and is located at the right hand front of the engine. Withdraw
the dipstick, and wipe with a paper towel. Replace the dipstick, if necessary feeding the blade into the tube with the towel, before
