2005 LOTUS ELISE Owners Manual

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.

DRIVING CONTROLS
Foot PedalsThe clutch pedal, brake pedal and accelerator pedal are ar
-
ranged in the usual positions, and are grouped closely together for ready access and refined driving technique.
WARNING: Do not attempt to drive the car without suitable narrow
soled, flat heeled footwear. Bare feet may inhibit the ap
-
plication of full pressure to the brake pedal, and adversely affect your control of the car. Bare feet could also suffer
burns from sun heated metal surfaces in the car
Footwell Carpets
WARNING: It is essential that any floor covering in the footwell is
properly secured. Loose mats can interfere with the opera
-
tion of the pedals causing possible loss of control and a crash in which you or others could be killed or seriously
injured.
The carpets fitted in the footwells of the Elise are secured by
two button screws at the rear, and Velcro strips beneath the front edge. Always ensure that the carpets are replaced and secured
correctly, and never fit any loose mats on top.
Clutch Pedal NOTICE:
• To avoid unnecessary clutch wear, do not, for more than
a few moments, slip the clutch to ‘hold’ the car on a slope;

apply the parking brake until ready to drive off.
• The clutch pedal must be fully depressed during each
gear shift.
• Do not drive with the left foot resting on the clutch pedal, as
rapid wear of the clutch components can result. A left foot rest
is provided for comfort and convenience.

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
67

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
Driving Controls

oh_croft_InD.indd 6820/05/2004 07:58:57ProCarManuals.com

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.

Parking BrakeThe parking brake, which operates on only the rear wheels
is applied by a hand lever mounted between the seats. A red
tell tale icon in the instrument cluster warns of parking brake application (see ‘Tell Tale Lamps’). The brake should be applied by pulling up the lever with high
effort, and engaging the highest ratchet setting attainable. When
parking the car on a slope take the additional precaution of leav
-
ing the transmission in first (facing downhill) or reverse (facing uphill) gear and steering the wheels towards the kerb.
WARNING: If the parking brake is applied when the brakes are hot
(e.g. after prolonged or frequent hard use), special care
should be taken to ensure that the parking brake is securely engaged in order to allow for any potential brake force
reduction as the discs cool. Failure to do so may result in
the car rolling away and causing an accident in which you
or others may be killed or seriously injured.
To release the brake, pull up the lever, press and hold the
release button in the end of the handgrip, and lower the lever fully.
Before driving off, always check that the parking brake has been
fully released, as confirmed by the tell tale icon being turned off,
or damage to the brake system may be caused. Note that the parking brake uses a cable mechanism to
apply the rear brake calipers, and is totally independent of the
footbrake hydraulic circuit.
