2005 LOTUS ELISE turn

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

Filler Cap: The fuel filler cap is located in the right hand rear
quarter panel, concealed beneath a spring loaded flap. To remove, pull open the flap and turn the cap anticlockwise.
As the cap is turned, any slight pressure differential between the tank and atmosphere will be released, and a brief hiss may be heard, which is completely normal. Note that the cap is tethered by a short strap to protect against loss.
To refit, place the cap into the filler neck and turn clockwise
until the ratchet mechanism clicks several times. Push the flap closed.
Filling Procedure:
Insert the pump nozzle fully into the neck, and
fill until the auto-shut off mechanism is triggered. Do not attempt to ‘brim’ the tank to the top of the filler neck, as expansion of the
fuel due to temperature change (cold underground fuel storage) may cause flooding of the fuel tank breather system charcoal
canister, or spillage of fuel. The useable fuel tank capacity is 10.6 U.S. gall. (40 litres).

Engine Cover/Trunk LidThe engine cover/trunk lid provides access to the engine and
rear luggage compartment.
To open the lid: Insert the key into the lock and turn clockwise. When released, a spring plunger will lift the lid sufficiently to allow it to be raised fully by hand. Support the lid by engaging
the prop provided on the trunk bulkhead, in the slotted plate adjacent to the latch mechanism.
WARNING:
• When using the rear luggage compartment, beware of any hot surfaces exposed in the engine bay. Touching hot

surfaces could cause serious burns.
• Before closing the lid, ensure that no persons or objects
will be trapped.
• If necessary, protect and/or secure heavy objects as required.
To close: Stow the support prop in its bulkhead clip, and, keeping
fingers well clear of entrapment, and ensuring that no obstruction is present, lower the lid. Fully engage the latch mechanism by pressing down on the lid just forward of the key lock, NOT at
the extreme rear end of the panel.

cover panel by locating first with the central screw, and then by the outer screws before tightening in the same order.
WARNING:
• Do not drive the car with the trim cover panels removed. Injury could result from contact with the roof brackets in
a car collision.
• Before driving check that the roof is secure by pulling upwards on each corner in turn. If any upward movement
is evident, check the correct fitment of all mounting brack

ets. An insecure or incorrectly fitted roof could cause
death or serious injury to other road users or a crash in
which you or others could be killed or seriously injured.

pressing firmly to ensure that the handle is fully seated. With-
draw the dipstick again to inspect the oil level, which should lie between the two dimples on the end of the stick. The oil level
should be maintained at the upper of these two marks in order
to provide optimum engine protection.
Topping Up
: If topping up is necessary, unscrew the oil filler cap
from the left hand end of the cam cover. Add a suitable quantity of the recommended engine oil (see ‘Recommended Lubricants’)
taking care not to spill any oil onto engine or electrical compo
-
nents; use a funnel if necessary. The difference between high and low dipstick marks is equiv

alent to 1.6 U.S. quarts (1.5 litre). Allow several minutes for the oil to drain through to the sump before re-checking the oil level.
Do NOT over fill, or lubrication will be degraded and consump

tion increased as the oil becomes aerated. Refit the filler cap,
turning clockwise until secure.
Engine Oil Change The use of high quality oil, renewed at the specified intervals,
is the key to engine longevity and sustained performance. Ad
-
here strictly to the engine oil and filter change intervals specified
in the Maintenance Schedule.
For access to the engine sump and filter, the engine bay
undertray must first be removed. This is most easily achieved
with the car raised on a garage hydraulic lift, or alternatively, parked over an inspection pit.
The drain plug is located at the rear of the sump, and should
be removed to drain the sump immediately after a run when
the oil is warm and the impurities are still held in suspension.
On cars fitted with front mounted oil coolers, it is not necessary routinely to attempt to drain the cooler circuit. Servicing & Maintenance

Oil FilterThe canister type oil filter is vertically mounted at the front
of the engine, and is accessible from beneath after removal of
the engine bay undertray. The filter should be renewed along
with the engine oil, at intervals specified in the Maintenance
Schedule.
WARNING:
• Engine oil is hazardous to your health and may be fatal
if swallowed.
• Take all suitable precautions to guard against scalding
from the hot oil.
• Prolonged and repeated contact with used engine oil may cause serious skin disorders, including dermatitis

and cancer.
• Use protective gloves to avoid contact with skin as far
as possible and wash thoroughly after any contact.
• Keep out of reach of children.
Remove the filter by turning in a counterclockwise direction,
if necessary using an oil filter wrench, and dispose of safely
(see ‘Used Engine Oil’). Ensure that only a Lotus specified filter is fitted, as parts with
identical outward appearance can contain different internal
features. Before fitting a new filter, clean the mating face on the engine, and smear the new seal on the filter with clean oil. Add

a small amount of clean engine oil into the filter, screw onto its
spigot and tighten BY HAND sufficiently to make a secure seal,
typically 2/3 to 3/4 of a turn after the sealing faces have made
contact. Overtightening using a filter wrench may damage the
canister and/or complicate subsequent removal. Before refitting the undertray, start the engine and check for
oil leaks. Re-check the security of the filter, further tightening
by hand if necessary. Check the oil level (see above) when the
engine is fully warm.
Used Engine Oil NOTICE: PROTECT THE ENVIRONMENT: Do not pollute
drains, water courses or land with oil. Use only authorised waste
collection facilities, including civic amenity sites and garages providing facilities for disposal of used oil and used oil filters. If
in doubt, contact your local authority for advice on disposal.
Transmission Oil The transmission should be checked for oil leaks, for the cor
-
rect oil level, and the oil renewed, at intervals specified in the
Maintenance Schedule.
To check the oil level:
- A garage lift or inspection pit must be used.
- Remove the engine bay undertray.
- Wipe clean the area around the socket headed level plug on
the front face of the transmission end casing.

As a precaution, every week when the engine is completely
COLD, and without disturbing the filler cap, check that the level of coolant in the translucent tank is between the ‘FULL’
and ‘LOW’ marks moulded on the front of the tank. If topping
up is required, wait until the coolant has fully cooled before
turning the cap a quarter turn counterclockwise and allowing any remaining pressure to escape. Only then may the cap be
completely unscrewed. In order to maintain protection from freezing damage and
metal corrosion, use only an approved coolant mixture (see below) to top up the tank to the ‘FULL’ mark. Refit the cap, and
turn clockwise until the leg on the cap locates in the slot at the
front of the tank.
NOTICE: If the cap is removed when the engine is warm, the coolant may boil and a small coolant loss may occur. The com
-
pletely cold header tank level should be checked at the first subsequent opportunity.
Cooling Fans
: Two cooling fans are fitted below the radiator in
the air intake duct. The fans are energised at high coolant tem
-
peratures, or when the air conditioning (if fitted) is selected. The
fans will also run if certain types of engine fault are detected, and
may operate during a 20 minute period following ignition switch off to prevent ‘hot soak’ boiling. An electric coolant circulation pump may also be heard running during this period.
WARNING: Keep hands, tools and clothing away from the radiator
cooling fan area, as personal injury could result from the
fans starting up without warning.
At service intervals, the air duct and matrices of the engine
cooling radiator, a.c. condenser and oil coolers, should be
checked externally for clogging by insects, leaves or other debris,
and if necessary, a water jet used to clear the finning. Take care not to damage or distort the delicate finning of the radiator or
the cooling performance will be degraded.
