LED Rear Lamps

Introduced on all 6-speed Elise variants for ’06 M.Y. are new rear lamp clusters incorporating LEDs in the

annular segments of the lamps. The central elements continue to use ﬁlament bulbs. The non-USA Elise also

adopts the USA centre high mounted stop lamp (CHMSL) featuring red LEDs behind a white lens. The light

emitting diodes are extremely durable and are serviced only by lamp cluster replacement. The turn indicators in

the centre of the outboard lamps, and the reverse lamps in the centre of the inboard units, use W16W bayonet

ﬁtting ﬁlament bulbs in twist release holders. Note that on USA cars, the outboard lamps are ﬁtted with ballast

modules secured by the lamp ﬁxing nuts.

MP.12 - 2008 M.Y. SUPPLEMENT

VEHICLE SECURITY ALARM

The Lotus Elise/Exige for ‘08 model year onwards is ﬁtted as standard with a PFK 457 immobiliser/alarm

which includes the following features:

•

Lotus branded transmitter key.

•

U.K. approval to Thatcham category 1.

•

‘Dynamic coding’ of the transmitter keys; Each time the transmitters are used, the encrypted rolling code

is changed to guard against unauthorised code capture.

•

Passive activation of immobiliser, central locking and alarm system.

•

Ingress protection using sensing switches on the latches of both doors, the front body access panels, and

the engine lid/tailgate.

•

Selectable cockpit intrusion sensing using a microwave sensor.

•

Self powered siren to maintain protection if the vehicle battery is disconnected.

•

Personal protection by ‘on demand’ activation of the siren.

•

Emergency alarm override and transmitter key programming using an alarm/owner speciﬁc Personal

Identiﬁcation Number (PIN).

Transmitter Keys

Two new Lotus designed and badged

transmitter keys are provided with the car, and

combine a mechanical key blade with a three

button transmitter unit incorporated into the

key head. The mechanical key operates the

ignition switch, emergency instruction door locks,

fuel ﬁller cap (not USA) and Elise engine/boot

lid. The transmitter operates the electronic

immobiliser, alarm system and the central

locking. The two transmitter keys should be

kept separate, and a replacement obtained

immediately after any loss to ensure that a

spare is always available.

The 4-digit code for the mechanical key, the unique serial number of the immobiliser/alarm, and the vehicle

owner’s 5-digit alarm Personal Identiﬁcation Number (PIN), are supplied on plastic tags attached to the key ring

of a new vehicle. In order to allow replacement transmitter keys to be programmed, it is essential that these

numbers are recorded and kept safely by the owner with the vehicle documents. It is also recommended that

the dealer stress this issue to their customers and, in the interests of customer service, keep a record in their

own database.

Replacement Keys: Additional or replacement transmitter keys may be purchased uncut/uncoded from Lotus

under part number A120H0008S and will be supplied with a blank mechanical blade for copy cutting to an existing

key. Alternatively, a cut key may be ordered from Bolton Lock Company, quoting the 4 digit ‘L’ key code, under

part number A120H0009S (using form LSL482c). In either case, the transmitter will then need matching to

the vehicle using the vehicle owner's 5-digit PIN, as described later in this bulletin.

Disarming the Alarm/Unlocking

When approaching the car, it is likely that the vehicle is locked and the alarm armed. The alarm red tell

tale lamp in the speedometer face will be triple ﬂashing. To disarm the alarm and unlock the doors:

Press the central, unlock, button on the transmitter key. The ﬁrst press will unlock just the driver’s door.

Two presses in quick succession will unlock both the driver and passenger doors.

This command will be acknowledged by a double ﬂash of the hazard lamps.

The engine will be mobilised (see below).

The interior lamp will fade on, and remain lit for up to 2 minutes (if set to the 'courtesy' position).

The alarm tell tale will be extinguished.

If a door is not opened within 2 minutes, the doors will passively re-lock and the alarm system re-arm.

Passive Immobilisation

In order to provide a measure of automatic vehicle security, independent of any driver initiative, the sys-

tem will ‘passively’ immobilise the engine’s cranking and fuel pump circuits after the ignition has been turned

off for 40 seconds, or a similar period has elapsed since the last mobilising command. With the ignition off,

the alarm tell tale will indicate that immobilisation is in effect by brieﬂy ﬂashing every second. With ignition on,

immobilisation is indicated by a continuously lit tell tale.

To mobilise the car (i.e. allow engine starting) with ignition on or off, press once the transmitter centre

button; the alarm tell tale will be extinguished.

Arming the Alarm/Locking the Doors

To lock the doors and arm the alarm, remove the ignition key, close both doors, and check that the engine

lid/tailgate and body front access panels are secure:

Press once the raised logo button on the transmitter fob.

This command will be acknowledged by a single ﬂash of the hazard lamps.

Both doors will be locked, the engine immobilised and the alarm system armed. A settling period of 40

seconds must expire before the ingress sensors become active.

The alarm tell tale will repeatedly triple ﬂash.

Note:

If the system is armed when a door is not fully shut, three

triple beeps will sound as a warning and the

doors will not be locked. Opening a door will not trigger the alarm.

ii) If the system is armed when the engine lid/tailgate or a front access panel is not fully closed, three warning

double beeps will be heard, and the doors will not be locked. Opening a door in this instance will trigger

the alarm.

iii) If one transmitter is used to disarm the alarm, and a second transmitter to re-arm, a system test mode will

be initiated, and operational variations will occur. Allow an undisturbed period of 2 minutes to elapse to

restore normal operation.

When fully armed, and after the settling period of 40 seconds has expired, the alarm will be triggered by

any of the following actions:

Interruption of the car battery power supply or siren cables.

Energising the ignition circuit (‘hot wiring’).

Opening a door;

Opening the engine lid/tailgate or a front access panel.

Movement detected within the cabin (unless de-selected).

If the alarm is triggered, the hazard warning lamps will ﬂash and the wailing siren sound for a period of

approximately 30 seconds before closing down and resetting, ready for any further triggering input. If a trigger

is continuously present (e.g. door left open), the alarm will repeat for a maximum of eight 30 second cycles

before excluding the triggering sensor for the remainder of the armed period.

To silence the siren, press once the central, disarm button on the transmitter key. If necessary, press a

second time to disarm the alarm.

Alarm Tell Tale Summary

Tell tale off; Alarm disarmed, engine mobilised.

Tell tale on; Immobilised with ignition on.

Brief ﬂash every second; Immobilised with ignition off.

Repeating triple ﬂash; Alarm armed.

Interior Movement Sensor

A microwave sensor is mounted behind the cabin rear bulkhead trim panel, and is able to detect substantial

physical movement within the cockpit, and trigger the alarm. Microwave transmissions are blocked by metal

objects, so it is important not to shield the signal by placing such items on the bulkhead ledge.

If an animal is to be left in the vehicle, or if for any other reason it is desired to exclude the interior move-

ment sensor when the alarm is set, press once the transmitter logo button in the normal way to set the alarm,

and then press a second time (within 2 seconds) to exclude the interior movement sensor. A single beep will

be heard as conﬁrmation. This exclusion will be automatically cancelled when the alarm is disarmed.

Section MP

The sensitivity of the sensor is factory

set for the Elise/Exige, and should never need

any adjustment. Such a faciltity is, however,

provided on the unit, and is accessible after

removal of the cabin rear bulkhead trim panel.

Turning the adjustment screw clockwise will

increase sensitivity.

Instruction Activation of Siren

If, for personal security reasons, it is desired to instructionly activate the siren at any time when the ignition

is off, press for 3 seconds the transmitter auxiliary (3rd) button. The wailing siren will sound, and the hazard

lamps ﬂash for a period of 30 seconds. To stop the siren, press once any of the transmitter buttons.

Instruction siren activation will not affect the status of the alarm arming.

Transmitter Key Battery Replacement

The transmitter keys will normally operate

within a range of 5 metres from the car, but this

may be reduced by the presence of other radio

signals in the vicinity. The transmitters are

CR2032, which with normal use should last for

3 years. To ensure continuity of operation, it

is recommended to renew the batteries every

12 months:

Using a small screwdriver, prise open the

back panel of the key case using the slot

by the keyring hole.

Remove the old battery and wait for 10 seconds before inserting the new battery with +ve sign uppermost,

and holding the battery only by the periphery.

Reﬁt the back panel, engaging the retaining tongue, and pressing ﬁrmly to engage the clip.

The transmitter should now operate normally.

Disconnecting the Vehicle Battery

In order to prevent the alarm being triggered, before disconnecting the vehicle battery, ensure that the

alarm is disarmed.

Emergency Disarming/Mobilising

If the key head transmitters are lost or damaged, the alarm system owner’s 5-digit PIN may be used to

disarm the alarm and start the engine

provided that the cabin is accessible, and a correct mechanical key

blade is available. Note that if the alarm is armed, accessing the cabin, or turning on the ignition will trigger the

alarm until completion of this emergency process.

Turn on the ignition. The alarm tell tale will light.

Within 10 seconds, turn the ignition off; the tell tale will begin to ﬂash.

After a number of ﬂashes corresponding to the ﬁrst digit of the PIN, turn on the ignition. Note that the ﬁrst

ﬂash may not be of full duration (but is still to be counted) dependent on the waveform position at time of

ignition switch off.

Turn off the ignition and after a number of ﬂashes corresponding to the second digit of the PIN, turn on

the ignition. Repeat this process until all 5 digits have been completed. Note that 10 ﬂashes correspond

to a zero digit.

If the PIN is entered correctly, the alarm will now be overridden and the engine mobilised. However, pas-

sive immobilisation will still occur after an ignition off time of 40 seconds, requiring a repeat of the above

procedure to mobilise. Passive arming and passive door locking cannot occur until a transmitter is used

to operate the alarm.
