If, at any stage of the process, a number is entered incorrectly, the system will immediately revert to the

start, so that the whole PIN must be re-entered.

Programming Additional Transmitters

A maximum of 6 transmitters may be programmed to the car, any thereafter overwriting the ﬁrst to have

been programmed.

With the engine immobilised (tell tale ﬂashes brieﬂy once per second), turn on the ignition.

Enter the PIN as detailed above, followed by the additional two digits 1, 1.

The tell tale will ﬂash rapidly for one second, then turn off.

Within 8 seconds, press any button on the transmitter to be programmed. The tell tale will then pulse

rapidly and the siren will beep.

Within 10 seconds press any button on the next transmitter to be programmed (if applicable), and repeat

this process for all remaining transmitters.

When all transmitters have been programmed, wait for 10 seconds, or turn off the ignition.

To disable a lost or stolen transmitter from the system, use the above procedure to programme 6 trans-

mitters, if necessary repeatedly reprogramming the same transmitter if less than 6 programmed transmitters

are to be used.

Trigger Report Back and Feature Selection

A facility is provided to identify the source of an alarm triggering event (trigger report back), as well as

allowing certain features of the system to be selected or de-selected. The same procedure described above

to input a PIN is used, but in this case to input the programming code '123'; the tell tale will then ﬂash rapidly

for 1 second, then remain lit. Commencing within 10 seconds, continue this procedure to input the two digits

of the feature code, after which the tell tale will ﬂash rapidly for 1 second then beep once or twice to indicate

the new status of that feature; one for 'ON', twice for 'OFF'. Selection will alternate each time that feature code

is entered. Note that within 10 seconds, a second feature code (or repeat) may be selected from this point by

entering only the 2-digit code. To exit programme mode, simply wait for 10 seconds.

Feature Code Default 1 Beep 2 Beeps

Revert to defaults 123 00

Trigger report back 123 11 see below

Unlock with ignition 123 33 OFF ON OFF

Lock with ignition 123 34 OFF ON OFF

Selective door unlock 123 41 ON ON OFF

Audible tones* 123 61 OFF ON OFF

Lock with auto re-arm 123 87 ON ON OFF

Door open audible warning 123 88 ON ON OFF

* When selected, a single beep will sound when the alarm is armed, and a double beep when disarmed. To

silence for a single activation, press brieﬂy the transmitter auxiliary (3rd) button prior to pressing the arm or

disarm button.

Trigger report back: After the code 12311 has been entered, the tell tale ﬂashes out a code(s) to indicate the

source of the alarm trigger:

No. of ﬂashes Triggering sensor

1 Microwave movement sensor

2 Door, bonnet or boot lid

3 Ignition energisation

4 Instruction siren activation

Quick Test

To facilitate testing of the alarm system, the unit can be placed into a 'Quick Test' mode by arming the

alarm with one transmitter key, and disarming with another. In this mode, the system will shorten the siren time

to 2 seconds, the immobiliser arm time to 5 seconds, and the settling time to zero. To exit this mode, simply

wait for 2 minutes without any further inputs.

Note that in Quick Test mode, any movement detected by the microwave sensor will trigger only the tell

tale and not the siren. The 2 minute timer will not be extended.

Component Location

The location of the PFK alarm components is unchanged from the equivalent earlier Cobra parts; the

controller is mounted on top of the scuttle beam at the LH extreme end. Access requires removal of the fascia

top. The immobiliser is incorporated into the controller as a single unit. The siren is mounted on the front of the

radiator duct LH extension, beneath the LHF turn lamp. Accessible only after removal of the front clamshell.

The microwave sensor is ﬁxed to the cabin rear bulkhead, requiring removal of the rear bulkhead trim panel

for access.

CDL Module; The Central Door Locking module is different on PFK cars, but is mounted in the same position

as previously, on top of the scuttle beam at the RH extreme end. Note that this unit is speciﬁc to PFK cars, and

does not require the inverter relay (on underside of scuttle beam) for inertia switch operation of the CDL.

TYRE PRESSURE MONITORING SYSTEM (TPMS) - USA ONLY

All USA Elise/Exige models from ‘08 model year onwards are ﬁtted with a tyre pressure monitoring system.

A sensor incorporated into each of the tyre valves monitors the air pressure inside the tyre, and supplies an

onboard control module with this data by radio transmission. If any tyre pressure should fall below 75% of the

recommended value, an alert message is sent to the instrument panel, and the tyre pressure tell tale

will light up amber. The fuel gauge display will then be overwritten with a message to indicate which tyre is

concerned, with text such as:

LF Low (left hand front tyre low pressure). This message will show for 5 seconds

before the display reverts to the fuel level bar graph, but will repeat for 5 seconds at 30 second intervals.

The TPMS incorporates self-malfunction recognition, and if a fault is detected, the tell tale will ﬂash for one

minute and then remain constantly lit. The LCD panel will also ﬂash ‘TPMS FAULT’ for 5 seconds, and repeat

at 30 second intervals; no indication of low tyre pressure will be displayed.

Tyre ﬁtters and service technicians should be made aware that TPMS is ﬁtted, and that the tyre valves

include pressure sensors. If the emergency tyre inﬂator aerosol has been used, it will be necessary to renew

the tyre valve/pressure sensor. If a fault is indicated after wheel or tyre replacement, it is likely that a sensor

has been incorrectly ﬁtted or damaged. If a tyre valve is renewed, or is moved to a different wheel position, the

TPMS will automatically identify the new conﬁguration.

Note that the pressure sensors are powered by integral batteries, with an average service life of 10 years.

It is recommended to renew all pressure sensors at this time interval.

WARNING ‘TELL TALE’ LAMPS

The instrument panel tell tales and LCD functionality have been revised for '08 M.Y. New features are

described below:

Security Tell Tale

The security function is separated from the combined security/rpm tell tale and is moved into the face of

the speedometer.

High RPM Tell Tales

Three red tell tales are incorporated into the tachometer face to warn that maximum engine speed is being

approached. Maximum transient engine speed in all gears at normal running temperature, is 8,500 rpm (7150

rpm for Elise S), at which point the engine is governed, but as the rate of rpm increase is potentially greater in

the lower gears, the tell tale trigger points are tailored to accommodate the reaction time available. As maximum

rpm is approached, the tell tales will light in the following left to right sequence:

one red light

two red lights

three rapidly ﬂashing lights

When exploiting maximum acceleration, gearchange upshifts should be made immediately the three

ﬂashing lights appear.

NOTICE:

A 6,000 rpm limit is imposed on a cold engine to reduce possible damage and wear from an unsympathetic

driving style.

At normal running temperature, maximum continuous engine speed is 8,000 rpm (6,800 rpm Elise S).

Using maximum rpm and the above tell tale facility should be restricted to occasions when maximum ac-

celeration is required. Overuse will compromise powertrain service life.

The engine is not protected from overspeeding caused by erroneous or premature downchanging. Such

misuse could result in catastrophic failure, not covered by the vehicle warranty.

SCHEDULED SERVICE TELL TALE (IF FITTED)

Under normal usage conditions, a routine maintenance service should be performed at the ﬁrst occurring

of 9,000 miles (15,000 km) or 12 months from the previous service (USA; 7,500 miles/6 months). The approved

service period extends to 500 miles before/after or one month before/after the stipulated distance/time.

As a driver aid to distance servicing, an amber wrench icon in the face of the speedometer will ﬂash for 10

seconds following each ignition turn on, when within 500 miles (800 km) of the service period, allowing plenty

of time for booking arrangements to be made. Once the service period is reached, the tell tale will remain

constantly lit with ignition until reset by your dealer.

Note that this feature is provided only as a secondary aid, and uses only

distance criteria, and not the

time factors which may predominate. It is the owner’s responsibility to ensure that servicing is carried out at

the prescribed intervals..

TRIP DISTANCE/DIGITAL SPEED DISPLAY/TIME CLOCK

The top left portion of the LCD panel may be cycled through the following displays:

Trip distance (in same units as analogue speedometer).

Digital road speed in alternative units to those indicated by the analogue instrument (either mph or km/

h).

Digital time clock (if ﬁtted - this feature will not be available initially).

To cycle, one at a time, through these three displays, brieﬂy press the small button on the right hand side

of the steering column shroud. (Note that this button also adjusts the brightness of the instrument and HVAC

panel illumination if held pressed when road speed is selected).

Trip distance: Units displayed are miles, and range from 000.0 to 999.9. To reset to zero; when the trip function

is displayed, press the button on the column shroud for longer than 1 second.

Time Clock Setting: To adjust the 24 hour time clock (if ﬁtted);

when the time function is displayed, press the button on the column shroud for longer than 1 second. The

hour display will then ﬂash.

Repeated brief presses of the button will increment the hour ﬁgure. Pressing the button for longer then 1

second will store the hour setting and start the minute display ﬂashing.

Further brief button presses will increment the minute ﬁgure.

When the correct time is displayed, press the button for longer than 1 second to store the setting and start

the clock.

VARIABLE TRACTION & LAUNCH CONTROL (IF FITTED)

Exige S models speciﬁed with the ‘Performance Pack’ option, include variable Lotus Traction Control

(LTC), allied with Variable Launch Control (see below) and have a rotary control knob mounted on the left hand

side of the steering column shroud.

Each time the ignition is turned on, normal full LTC is activated. To enable variable traction control, turn

on the ignition and hold the LTC ‘off’ button pressed for 2 seconds. Check that the tell tale in the switch button

is lit. Start the engine. Note that if the ignition is switched off (e.g. prior to a second start attempt), the above

procedure must be repeated in sequence.

With the switch button tell tale lit and the engine running, the rotary knob may then be used to select the

degree of traction control desired, with the setting shown on the instrument panel LCD in the form ‘#% SLIP’, with

a possible range between 0 and 9%. The display will revert to showing the fuel level after a few seconds.

•

For maximum traction control (0% slip) turn the knob fully counterclockwise to ‘MAX’.

•

To reduce traction control (to allow up to 9% slip), turn the knob progressively clockwise.

•

Fully clockwise (‘0’), traction control is disabled, as indicated by the lighting of the instrument panel tell

tale, and an LCD message of ‘LTC OFF’.

If at any time during that ignition cycle, the control knob is turned, the LCD will again show the traction

control setting for a few seconds.

When the ignition is next turned on, normal full LTC will be activated unless the above procedure is re-

peated.

Variable Launch Control

CAUTION: This feature is designed for competition use, and as such, its employment will invalidate

vehicle warranty on any components subject to the extreme loads associated with racing starts.

Variable Launch Control allows the engine rpm to be limited during a competition start in order to balance

engine power against available grip and provide a controlled degree of wheelspin for the ﬁrst moment of ac-

celeration, until superseded by the traction control system at around 6 mph.

To enable this feature, turn on the ignition and hold the LTC ‘off’ button pressed for 2 seconds. Check that

the tell tale in the switch button is lit. Then;

•

With ignition on, engine

stopped, fully depress the throttle pedal for 5 seconds.

•

Tacho will now show launch rpm. Turn the rotary knob as necessary to select any desired launch rpm

between 2000 and 8000.

•

Release throttle and start engine.

•

Turn the rotary knob to select the desired level of traction control (see above), noting that the launch control

setting will not be affected.

•

Engage ﬁrst gear, apply full throttle (ECU limits engine speed to selected launch rpm), and rapidly ‘drop’

clutch.

•

Maintain full throttle throughout the transition from launch to traction control (at around 6 mph) until the

ﬁrst gear change is required.

•

To disable launch control when variable traction control is still required, reset launch rpm to 8,000.

NOTE

•

Do not attempt to slip the clutch during this process, as overheating or damage to the clutch mechanism

may occur. An instant clutch engagement is required to ‘break’ rear tyre traction and initiate wheelspin.

Note that an hydraulic damper valve is incorporated into the clutch release pipework to protect the driveline

from excessive shock loading when using this technique.

•

Do not attempt LC starts in any gear other than ﬁrst.

•

Do not hold the engine at or near maximum rpm for more than a few seconds.

•

Under no circumstances should this track feature be employed on the public road.
