2005 LOTUS ELISE catalytic

Engine Exhaust
California Proposition 65 Warning
WARNING: Engine exhaust, some of its constituents, and certain
car components contain or emit chemicals known to the
State of California to cause cancer and birth defects or other reproductive harm. In addition, certain fluids contained in cars and certain
products of component wear contain or emit chemicals
known to the State of California to cause cancer and birth
defects or other reproductive harm.
WARNING: If you ever suspect exhaust gas is entering the cockpit,
do not drive the car until the fault has been repaired.
In particular, running the engine in an enclosed space
can let exhaust gas into the car, even more quickly if the interior fan is switched on. NEVER park in a garage with the engine running.
WARNING:Engine exhaust can kill. It contains the gas carbon
monoxide (CO), which you can’t see or smell. It can cause
unconsciousness and death. You might have exhaust gas entering the cockpit if:
• Your exhaust system sounds strange or different.
• Your car was damaged in a collision.
• Your car was damaged when driving over high points in the
road or over road debris.
• Repairs weren’t carried out correctly.
• Your car or exhaust system had been modified improperly.
Make sure your car is checked by an authorised dealer before
driving it again.
NOTICE: The Elise is fitted with a ‘three way’ catalytic converter
in the exhaust system in order to reduce the noxious content of
the exhaust gases and comply with emission control regulations.
It is essential that ONLY UNLEADED FUEL is used (see ‘Fuel Requirement’). The use of leaded fuel, or lead replacement

petrol (LRP), will cause irreversible contamination of the pre-
cious metal catalysts and of the exhaust gas sensor used by the
computer controlled engine management system.
It is important that the Maintenance Schedule (see separate
booklet) is followed at the specified time and distance intervals
(this is a requirement of the warranty), and that the car is kept in proper operating condition. Failure to do so may result not only
in a loss of fuel economy and emission control, but may cause damage to the catalytic converter.
WARNING:
• If the engine malfunctions in any way (e.g by a change in sound) have the fault diagnosed and repaired promptly.
Continuing to drive the car with an engine misfire could cause the catalytic converter to overheat, with possible heat damage to other car components, and an engine bay
fire. Operation of the ‘Malfunction Indicator Lamp’ (MIL)
is fully described later in this handbook on page 49.
• DO NOT park or drive the car in areas where combustible material, such as dry grass or leaves, could come into
contact with the hot exhaust system. Under certain wind and weather conditions a grass fire could be initiated.
• DO NOT tamper with any electrical components with the battery connected. You could receive an electric shock
from the spark plug coils or initiate a car fire.
• DO NOT check or adjust any engine bay equipment with the engine running. Failure to comply with this may result
in you or your clothing becoming trapped.
• DO NOT use the car if a fuel leak is suspected, as may be indicated by a persistent smell of fuel. Have the fault

diagnosed and rectified without delay. A fuel leak may result in a fire or explosion.
• DO NOT touch or approach, any part of a hot exhaust

system. Failure to comply with this may result in you
receiving severe burns.
• DO NOT allow servicing or repairs to be carried out by unskilled persons as this may adversely affect the han
-
dling and safety features on your car. Lotus dealers have
trained staff who are best qualified to maintain your car
to the correct specification.

NOTICE: DO NOT push or tow start the car; or turn off the igni-
tion at engine speeds above idle; or run the fuel tank dry: Any of these actions may damage the catalytic converter.
Before driving the car:
• Check tires for damage, wear and proper inflation.
Under-infla-
tion causes increased rolling resistance and uses more fuel.

(Please refer to the section in this handbook on tires, page 115).
• Check all windows, mirrors and lights are clear and unob
-
structed and all lights are correctly working.
• Check that the engine cover and front body access panels
are correctly latched;
• Adjust the seat and mirrors, and familiarise yourself with

the controls.
• Check all instruments and warning lamps (‘tell tales’) are reading correctly.
• Ensure that both driver and passenger are properly restrained
by their seat belts.
Care of the Environment By virtue of its light weight, simple content, constructional
process and fuel efficiency, the Elise has a low environmental im
-
pact compared with many road cars. All drivers should, however,
be aware of the effect of motor car exhaust emissions on the
environment and drive in a way which minimises pollution by:
• Anticipating traffic flow to avoid needless acceleration

and braking.
• Using the highest suitable gear.
• Switching off rather than idling for long periods.
• Driving off as soon as it is safe to do so; it is not necessary or beneficial to the engine to allow extended idling from cold.
• Having the car serviced regularly as a poorly maintained car will use more fuel; have any engine faults attended to imme
-
diately.
• Considering the need to use the car for very short journeys.
The emissions produced by an engine are many times greater
when cold than when warm.

will also disable the engine coolant pump and result in rapid overheating; stop the engine as soon as it is safe to do so, and
summon assistance. If the drive belt is intact and the cooling
system unaffected, it may be possible in favourable daylight conditions, to drive a short distance to a repair facility, but do not, under any circumstances, allow the battery to become
completely discharged by continuing to drive.
Engine Malfunction Indicator Lamp
The engine Malfunction Indicator Lamp (MIL) is provided to
warn the driver that the engine management system has de
-
tected a fault which may result in increased noxious emissions from the exhaust. In order to minimise emissions and potential
engine damage, various operational limitations may automati
-
cally be applied. i) If the MIL lights continuously whilst driving, immediately reduce
speed and adopt a moderate driving style. Seek dealer advice
without delay and avoid all unnecessary journeys.
ii) If the MIL flashes, an engine misfire has been detected which is likely to cause overheat damage to the catalytic converter.
Slow down immediately and be prepared to stop.
- If the MIL then stops flashing, and is lit continuously, proceed with caution and seek dealer advice.
- If the MIL continues to flash, stop the car as soon as it is safe to do so, and switch off the engine. Seek dealer advice.
NOTICE:
Continuing to drive the car with a flashing MIL may
cause overheat damage to the catalytic converter, possible en
-
gine damage, increased emissions, and impaired fuel economy and driveability.
In order to comply with emissions regulations, data regarding
activation of the MIL is recorded in the engine electronic control
-
ler, and may be downloaded by Lotus dealers.
Security/RPM Tell Tale The security tell tale is located at the top of the tachometer
display, and indicates the status of the immobiliser and alarm.
• Tell tale out; engine is mobilised, and the alarm is off.
• Tell tale flashing; engine is immobilised, or alarm is armed
and engine immobilised.
For full details of the car security system, refer to the earlier
section ‘Car Security’.

When only a single segment remains, representing approxi-
mately 1.3 U.S. gall. (5 litres), the amber low fuel tell tale will
flash. Refuel at the next opportunity.
NOTICE: Do not allow the tank to run completely dry, as this may damage the catalytic converter and fuel pump. This may
affect the terms of your warranty.
Coolant Temperature Display The engine coolant temperature will be displayed at the bot
-
tom right hand corner of the panel as soon as the temperature reaches 162°F. The running temperature will fluctuate a cer
-
tain amount as the operating conditions change, and during periods of idling or in heavy traffic, the temperature may rise to
over 212°F, with the cooling fans switching on at half speed at
approximately 208°F and at full speed at approximately 217°F.
The temperature display will flash at temperatures over 226°F to prompt closer monitoring by the driver of high temperatures.
The pressurised cooling system has a boiling point of over 248°F.

If the temperature approaches this level then the driver should be concerned. If this should occur, allow the engine to idle for a
few minutes whilst monitoring the temperature, and if it continues to rise, switch off and seek qualified assistance.
NOTICE: After a heavy snowfall, ensure that the radiator cooling
outlet grilles in the front body are cleared of snow before driving
the car, or overheating may occur.
Odometer An odometer (total distance recorder) reading is displayed at
the bottom left hand corner of the panel.
Trip Recorder A trip distance recorder is provided at the top left hand corner
of the panel. In order to zero the trip display, switch on the ignition, and
press for a moment (less than 1 second), the small button
on the steering column shroud ahead of the ignition switch.

This dual function button also controls the panel illumination
- see ‘Instrument & Switch Illumination’.

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

EXTERNAL OPERATIONS
Fuel Requirement USE UNLEADED PREMIUM GR ADE GASOLINE.
Use only unleaded gasoline meeting ASTM specifications.
Use of fuels not meeting ASTM specifications could cause poor performance and increase emissions.
For optimum car performance and fuel economy, the use
of super or premium unleaded gasoline, with a minimum
octane rating of 91 (RON+MON)/2 is recommended. Where
super or premium fuel is not available, the Elise will operate
satisfactorily on unleaded gasoline having a minimum rating
of 87 (RON+MON)/2, but car performance and economy will be reduced. Using fuel with a lower octane rating may cause knocking
(pinking) which, if severe, can cause serious engine damage.
Light knocking may occasionally be heard for short periods when accelerating or driving up hills, and this should cause no concern,
although using a lower gear would be advised. If, however, you hear persistent heavy knocking when using the specified fuel,
consult your dealer without delay.
The use of good quality fuels containing proper detergent ad
-
ditives is advised for good performance and emission control.
NOTICE: Do NOT use leaded fuel: damage caused by the use of leaded or other improper fuel is not covered by the New Car
or Emission Control System Warranty. The effectiveness of
the catalytic converter decreases after as little as one tankful
of leaded fuel. Also, the car is fitted with a fuel injection system
which includes an oxygen sensor. Leaded fuel will damage the sensor, and cause emission control to deteriorate.
Gasolines Containing Alcohol - Some gasolines sold at service stations contain alcohol although they may not be so identified.
Use of fuels containing alcohol is not recommended, unless the nature of the blend can be determined as being satisfactory.
Gasohol - A mixture of 10% ethanol (grain alcohol) and 90% unleaded gasoline may be used in the Lotus Elise. If driveabil
-
ity problems are experienced as a result of using gasohol, it is recommended that the car is operated on gasoline.

v) A spark will occur at the first disconnection of a jumper cable, so it is essential that the first disconnection is made from the
slave car earth. Both batteries (especially the
discharged one) will be ‘gassing’ heavily at this time, and if the first disconnection is made at a battery terminal, there is
a danger that the hydrogen gas may be ignited by the spark
with a resultant explosion.
vi) Have the cause of the flat battery investigated and rectified,
and trickle charge the battery as detailed above.
WARNING:
• Risk of damage and serious personal injury due to

shortcircuit.
• Use only jumper cables of adequate cross-section, fitted
with completely insulated alligator clamps. The cables must be long enough to allow that neither cars nor cables
touch each other.
• Follow all warnings and instructions of the jumper cable
manufacturer.
• When connnecting the jumper cables, keep them away
from engine moving parts.
• The two cars must not contact each other, or current could flow as soon as the positive terminals are connected.
• When the first clamp on each cable is connected, the other clamp on that cable must be held carefully to make sure it does not come into contact with either another cable
clamp or either car.
• Ensure that tools or metal watches or jewellery do not contact the battery terminals or live car parts.
NOTICE:

• Improper jumper cable connection can damage the alternator
and other electrical components.
• Do not attempt to push or tow start the car, as damage to the
catalytic converter or other parts could be caused.
