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.

- Remove the plug, and check that the oil is level with the bottom of the hole. Note that the release of oil trapped
by the plug, should not be confused with an indication of

correct oil level.
- If necessary, add only the specified lubricant (see ‘Recom
-
mended Lubricants’) via the level plug hole until the oil level
stabilises at the bottom of the plug hole.
- Refit the level plug with a new sealing washer, and tighten securely. Refit the undertray.
To renew transmission oil:
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.

Use only a non-mineral type DOT 4 brake fluid from a sealed
container marked with a yellow and black (non-mineral) symbol.
Do not use DOT 5 silicone fluid, or any fluid which has been
exposed to the atmosphere for more than a brief period, or
any fluid suspected of being wet, dirty or contaminated. Do not over fill, and replace the cap securely. Brake fluid, being hygroscopic, absorbs water from the atmos
-
phere over a period of time, resulting in a lowering of the boiling
point of the fluid, and corrosion of the hydraulic system. For
optimum safety and brake performance, the brake fluid should be renewed every twelve months by your Lotus Dealer.
WARNING:
• Brake fluid is hazardous to health and may be fatal if swallowed. Keep out of children’s reach.
• Using the wrong type of brake fluid can damage brake system components and result in brake failure causing a
crash in which you and others could be killed or seriously
injured. See ‘Recommended Lubricants’.
Brake Pads The thickness of the brake pad lining material should be
checked at every service, and under no circumstances be al
-
lowed to fall below 0.1 inch (2.5 mm). If the brakes are in very frequent or arduous use, as when driving in mountainous terrain,
or on race circuits, it is recommended that they be examined
more frequently. The pads should be renewed if of insufficient
thickness to ensure safe braking until the next scheduled service.
Note that in order to ensure that brake pads with the correct
material specification are used, only genuine Lotus replacement parts should be fitted, and in the interests of safety, pad renewal
should be entrusted to your Lotus dealer.
WARNING: Using incorrect brake pads, or pads below 0.1 inch
(2.5mm) thickness, may cause a crash in which you or
others could be killed or seriously injured. With a new car, or new brake system components, maxi
-
mum braking efficiency will be achieved if, for the first few
hundred miles, needless heavy braking is avoided, and the
brake pads and discs are allowed to ‘bed in’ fully before
being used to their full potential (see also ‘Footbrake’).

Air Cleaner ElementThe air filter should be inspected at intervals dependent on
the operating conditions. When the car is operated in a relatively
clean environment, the element should be renewed at intervals
specified in the Maintenance Schedule, but where a dusty or
smog laden atmosphere prevails, or other factors contribute to
filter contamination, more frequent replacement will be required
dependent on the level of pollution. A disposable folded paper type air cleaner element is fitted in
a housing at the left hand front of the engine bay. For access to
the element, the left hand rear wheel and wheelarch liner must
first be removed so this operation is best entrusted to your dealer.
Before opening the air cleaner housing, the wheelarch area
should be cleaned to reduce the possibility of filter or housing contamination with road dirt. To open the filter housing, release the two spring clips at the
outboard end of the housing, and hinge open sufficiently to allow
the element to be removed. If necessary, remove the air intake scroll for improved access. Clean the inside of the housing, including the joint faces,
taking care not to contaminate the ‘clean’ engine side of the as
-
sembly. Fit the new filter element into position with the shallow
side towards the engine, and taking care to ensure that the two
hinges of the filter housing are properly mated, and that the filter
is seated correctly, close the housing and secure with the two
spring clips. Refit the wheelarch liner and rear wheel.

Other tire markings are self explanatory.
Tire Inflator Aerosol (if fitted) In order fully to exploit the benefits of light weight, and
to maximise stowage space, the Elise has no provision for spare wheel carriage or lifting jack. A temporary puncture
repair facility is provided in the form of a tire inflator aerosol
which is mounted in spring clips at the extreme right hand front corner of the rear luggage compartment. If possible avoid driving on a deflated tire, or irreparable damage to
the tire may be caused. When the aerosol is connected to the tire valve, and the
button pressed, a mixture of liquid latex and propellant is
injected into the tire, such that the solidifying latex is forced
into the puncture site at the same time as the tire is inflated, effecting a temporary repair and enabling the car to be driven at low speed to the nearest tire repair facility.
WARNING:
• Use of the aerosol does not constitute a permanent repair, but is designed to allow the car to be driven
to the nearest tire repair facility. At the earliest op
-
portunity, the tire should be either professionally repaired or replaced dependent on the severity of
the damage.
• Until the tire is repaired or replaced, the car should be driven in a moderate manner, not exceeding 30
mph (45 km/h).
• Do not use the aerosol for large holes or repairs, or when the tire sidewall has been damaged, or if the
tire has been displaced from the rim.
• For safety reasons, the aerosol should at all times be carried only in the designated secure stowage
position. Never carry loose in the passenger com
-
partment.

WheelsEnsure that only original equipment, or Lotus approved wheel
and tire combinations are fitted. After the car has been used
on track, or in competition conditions, the wheels should be removed and thoroughly inspected for damage.
WARNING: After striking a pothole or kerb, the wheels should be
removed and the wheel and tire thoroughly inspected for
damage. Renew the wheel and /or tire if necessary. Safety
considerations should always be paramount and new parts
fitted in any cases of doubt.
Wheel Bolts The wheel bolts used on the Elise are of a special design to
suit the small diameter fixing tunnels in the wheel centres. The bolts have a 10 spline socket head, for which a special extension
tool is supplied with the car. A 17mm a/f deep socket and 1/2
inch square drive wrench should be applied to the extension tool,
with a tightening torque of 77 lbf.ft (105 Nm) required. To protect against wheel theft, one of the four bolts securing
each wheel is key coded, and requires a corresponding coded
socket wrench and 1/2 inch square drive extension. Rotate the coded socket until full engagement with the bolt head is ensured and take care to maintain the extension tool perpendicular to
the wheel face before applying release torque.
NOTICE: It is not recommended to use hammer action air tools on the coded bolts - use only manual tools.
Both the standard extension and coded socket tools are
stowed in the car tool kit, and should remain with the car at all
times to ensure that servicing may be performed. The key code
included in the tool kit should be recorded and kept safely with
the car documents, in case a replacement socket tool needs
to be ordered.
Wheel Alignment and Tire Balance The wheels on your car were aligned and balanced carefully
during the manufacture of your car to give you the longest tire
life and best overall performance.
