2005 LOTUS ELISE Owners Manual

WARNING:Inexper t modifications or additions to the electrical
system could jeopardise safety.
Inertia Switch The safety inertia switch is designed to operate on impact,
typified by car collision, to switch off the fuel pump, and thus
minimise any fire hazard. The central door locking will also be
triggered to unlock the doors. The inertia switch is mounted at the left hand bottom of the
engine bay, on the inboard face of the rear subframe, and is ac
-
cessible from between the coolant header tank and windscreen
washer reservoir. The switch is reset by pressing the rubber
diaphragm button on the top of the unit.
Fuses The main fusebox is located in the front services compartment,
on the passenger side, and is protected by a plastic cover. For
access, remove the passenger side front body access panel,
and unclip the fusebox lid. Twenty two slots are provided for ‘Littel’ type fuses which are
numbered, and coloured according to their amperage rating, and
may be pulled out from their slots using the fuse extractor tool provided on the fusebox lid.

WARNING:Replacing a fuse with one which has a higher rating may
cause extensive damage to the electrical system and pos
-
sibly cause a fire. If a fuse of the correct rating is not avail
-
able, use one of a lower rating as a temporary measure.

Engine Compartment FusesFuses associated with the engine management system are
contained in two 4-position fuse holders located at the front of
the engine bay on the cabin bulkhead, adjacent to the engine ECM. To access the fuses, unclip rear edge of the cover.

WARNING:
• To avoid injury, beware of rotating engine components and guard against entrapment of body parts, tools and
loose clothing.
• Stop engine before servicing fuses.
• Beware of hot surfaces in the engine bay. You could be seriously burned if you touch a hot engine part.
• Take great care not to drop flammable liquids or objects onto a hot engine and start a fire.

Headlamp AlignmentThe headlamps of your Elise were correctly adjusted during
the manufacture of the car, and should only require subsequent
adjustment if the headlamp assembly or front body is disturbed.
Simply replacing the bulb will not affect alignment. Incorrectly adjusted headlamps can cause poor lighting performance or dazzle to oncoming traf fic. Special headlamp setting equip
-
ment is required to correctly set the headlamps, such that only
qualified technicians using appropriate equipment should be
entrusted with this procedure:
1. Using beam setting equipment compatible with local regu
-
lations, position the machine between 300 and 700mm in
front of the LH headlamp, and parallel with the two headlamp
units using the sight bar or similar device dependent on the machine design, to ensure cross car match. Use the guides provided on the machine to ensure the correct height and
lateral setting.
2. Switch on the headlamp low beams (uppermost lamps) and check the lateral beam alignment. The ‘knee point’ of the beam cut off line must lie within a tolerance of 2% to the pas
-
senger side, and 0%. Check the vertical alignment of the low beam which must lie within a tolerance of - 0.5% and -2%.

3. If adjustment is required, the clear cover and mask must be removed from the body. From within the wheelarch, remove
the access panel from the wheelarch liner to expose the
headlamp cover retaining screws. Use the hexagonal key provided in the toolkit (in the rear pocket on the batter y
cover) to release the three socket head retaining screws and washers, and withdraw the cover assembly complete
with rubber edge seal from the body. When refitting, do not overtighten the fixings.
4. To adjust the low beam laterally, adjust the dome headed screw at the upper inboard side of the low beam (uppermost)
lamp, accessed from the front of the lamp. Turn clockwise to
adjust the beam to the right. Optimum setting is 0%. To adjust
the vertical aim of the low beam, adjust the dome headed screw at the lower outboard side of the lamp, accessed
from the front of the lamp. Turn clockwise to raise the beam.
Optimum setting is -1.5%.
5. Repeat for the RH lamp. 6. Centralise the machine on the LH high beam (lowermost) lamp, and switch on the high beams. Check the high beam
alignment which should be centralised with the marker dot on
the machine screen or slightly below the horizontal. Optimum
setting is 0%.

- To adjust the high beam laterally, adjust the dome headed screw at the upper inboard side of the lamp, accessed from behind the lamp. Turn clockwise to adjust the beam to the
right.
- To adjust the vertical aim of the high beam, adjust the dome headed screw at the lower outboard side of the lamp, ac

beam.
7. Repeat for the RH lamp. 8. Re-fit the cover/mask assemblies complete with edge seal to the body, and secure with the three socket head screws and
washers. Refit the wheelarch access panel.

BULB REPLACEMENT
Headlamp BulbMounted in the front body are the two headlamp units, each
of which houses a halogen projector type low beam lamp
(upper), and a halogen high beam lamp (lower) including the sidelamp bulb. For access to the headlamp bulbs, first remove the clear cover
and mask from the body (see previous pages).
WARNING:
• Allow bulbs to cool before attempting removal, or your fingers could be burnt.
• Halogen bulbs have pressurised gas inside and can burst if you drop or scratch the bulb. You or others could be
injured.
• Be sure to read and follow instructions on the bulb

packaging.
NOTICE: Do not touch a halogen bulb glass envelope with the
fingers, as the greasy deposit left behind will greatly reduce bulb life. Use a paper tissue to handle the bulb.
Low beam bulb: Disconnect the single cable, release the spring wire clip, and withdraw the 55W H1 bulb. On refitting, note that the bulb is keyed to allow only one orientation.
