2005 LOTUS ELISE brake

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.

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.

STARTING PROCEDURE & ENGINE BREAK-IN
WARNING:CARBON MONOXIDE - Be aware of the danger of carbon
monoxide! Never run the engine in an enclosed space. The
exhaust gases contain carbon monoxide, a deadly gas
which is particularly dangerous, as being colourless odour
-
less and tasteless, its presence is very difficult to detect.
Before starting the engine, always check that the parking
brake is firmly applied, the transmission is in neutral, and as
an extra precaution, depress the clutch pedal. Switch off any
unnecessary electrical loads.
Starting a Cold or Warm Engine
The fuel injection and engine management system controls fuel delivery and engine settings under all normal operating conditions.
i) Insert the key into the steering lock/ignition switch and turn to
position ‘l’ to unlock the column. Before turning on the igni

tion; if the security tell tale in the tachometer face is flashing, mobilise the engine by pressing once, and for a full second,
the larger of the two buttons on the transmitter fob.
ii) Turn the key to position ‘II’ to switch on the ignition, and pause
for a moment to allow the fuel system to prime.
iii) Depress the clutch pedal as a precaution, and without moving
the accelerator, press the ‘Start’ button at the left hand end of
the dashboard to engage the starter motor. Release the button
as soon as the engine starts. Allow a cold engine to idle for
10 seconds before driving off, but if ambient temperatures are below freezing, allow the engine and screen heating systems
to warm up for a few minutes before driving.
iv) If the engine fails to start within 15 seconds, stop cranking
and pause for 10 seconds before a second attempt.
v) If further efforts are unsuccessful, contact your dealer or seek
other expert help.
WARNING:
An unattended car with a running engine is potentially
hazardous. Turn off the engine before leaving the car.

NOTICE: The use of wide throttle openings and/or high rpm before the engine has reached normal running temperature will
result in premature wear, and should be avoided.
Idle Speed Engine idle speed is controlled electronically by the engine
management computer, and is normally about 850 rpm. A
raised idle speed is required under certain operating conditions
including the engine warm up phase, when the increased speed helps the catalytic converter to reach operating temperature, as
well as inhibiting engine stall. Idle speed will return to normal automatically when the engine has warmed sufficiently.
Engine Break-In Although the Elise powertrain is built to close tolerances
using modern technology, the progressive and sympathetic
breaking-in (or bedding-in) of a new engine and transmission
remains a major factor in attaining ef ficient operation with
smooth, durable and economic performance to last throughout
the life of the car.
NOTICE: Failure to comply with the following break-in provi
-
sions could invalidate the terms of the car warranty:
It is important during the car’s early life to limit the workload on
the engine and thus control the heat generated within it, which is primarily a function of throttle opening and rpm. However, being
too sympathetic on the car will not allow the piston rings to bed in
satisfactorily, so a balance of spirited and gentle use is required.
For the first 600 miles (1,000 km), use no more than moderate
throttle openings (about half of the available accelerator pedal
travel) and do not run the engine continuously at engine speeds over 4,500 rpm. Occasional short bursts at wider throttle and
higher rpm will be beneficial, as will a constantly changing cruis

ing speed and making full use of the gearbox. Do not allow the
engine to labour in too high a gear ratio, but change down and
let the engine operate in its natural power band. When changing gear, use only a light touch on the gear lever.
Forcing the change will cause unnecessary wear on the system components and result in higher shift efforts being required. Al

REMOVING ACCESS PANEL
Front Service Access PanelsThe front body has two removable access panels to allow
servicing of the brake/clutch fluid reservoir and main fusebox.
To remove an access panel:
Use the hexagonal key supplied
in the car tool kit (in the battery cover rear pocket), to release
the single threaded fastener securing the outboard corner of
the panel, and withdraw the panel from the two locating holes in the front body spine. Guard against the lightweight panel being blown away and
damaged by a strong wind.
To refit a panel: Hook the extended lip on the front edge of the panel beneath the rear edge of the louvre panel before engaging
the two locating pegs on the inboard side of the access panel
with the holes in the front body spine. Fit the single screw at
the outboard corner of the panel into the captive nut in the body,
taking care not to cross-thread or overtighten the screw. Re-stow
the hexagonal key in the tool kit.
WARNING: Ensure the access panels are refitted and properly se
-
cured before driving.

Brake Fluid ReservoirUnder normal circumstances, there is no requirement for
routine 'topping up' of the brake master cylinder reservoir. A
visual safety check is all that is required. Every week, check the level of fluid in the brake fluid reservoir
located in the driver’s side of the front services compartment, beneath the access panel: Without disturbing the filler cap,
check that the level lies between the 'MA X' and 'MIN' marks moulded on the translucent reservoir body. As the brake pads
wear, the level will drop gradually from the 'MA X' mark towards the 'MIN', but if the level drops rapidly over a short period, have
your Lotus dealer investigate without delay. If the level is found
to be below the 'MIN’ mark, it is likely there has been some fluid loss, and that air will have entered the hydraulic system. The car
should not be driven until the fault has been investigated and rectified. Note that a single reservoir is used to supply both of
the independent hydraulic circuits for the front and rear brakes, and also serves the hydraulic clutch release circuit. If any fluid is to be added, first clean the surrounding area
to guard against dirt ingress before unscrewing the reservoir cap.
NOTICE: Spilled brake fluid can seriously damage the car’s paintwork and some plastic compoments, for example, the side
marker lamps. Take suitable precautions to protect the paintwork
from contamination, and in case of spillage, rinse the affected area with water immediately: DO NOT WIPE.

oh_croft_InD.indd 11020/05/2004 07:59:08ProCarManuals.com

Use only a non-mineral type DOT 4 brake fluid from a sealed
container marked with a yellow and black (non-mineral) symbol.
Do not use DOT 5 silicone fluid, or any fluid which has been
exposed to the atmosphere for more than a brief period, or
any fluid suspected of being wet, dirty or contaminated. Do not over fill, and replace the cap securely. Brake fluid, being hygroscopic, absorbs water from the atmos
-
phere over a period of time, resulting in a lowering of the boiling
point of the fluid, and corrosion of the hydraulic system. For
optimum safety and brake performance, the brake fluid should be renewed every twelve months by your Lotus Dealer.
WARNING:
• Brake fluid is hazardous to health and may be fatal if swallowed. Keep out of children’s reach.
• Using the wrong type of brake fluid can damage brake system components and result in brake failure causing a
crash in which you and others could be killed or seriously
injured. See ‘Recommended Lubricants’.
Brake Pads The thickness of the brake pad lining material should be
checked at every service, and under no circumstances be al
-
lowed to fall below 0.1 inch (2.5 mm). If the brakes are in very frequent or arduous use, as when driving in mountainous terrain,
or on race circuits, it is recommended that they be examined
more frequently. The pads should be renewed if of insufficient
thickness to ensure safe braking until the next scheduled service.
Note that in order to ensure that brake pads with the correct
material specification are used, only genuine Lotus replacement parts should be fitted, and in the interests of safety, pad renewal
should be entrusted to your Lotus dealer.
WARNING: Using incorrect brake pads, or pads below 0.1 inch
(2.5mm) thickness, may cause a crash in which you or
others could be killed or seriously injured. With a new car, or new brake system components, maxi
-
mum braking efficiency will be achieved if, for the first few
hundred miles, needless heavy braking is avoided, and the
brake pads and discs are allowed to ‘bed in’ fully before
being used to their full potential (see also ‘Footbrake’).
