tire type LOTUS ELISE 2005 Owners Manual

Soft Top Roof
1. Careful vacuuming of the soft top before washing may be
helpful in removing excess dust and other foreign particles.
2. Wash in partial shade rather than strong sunlight.
3. Using only clean lukewarm water and a sponge (a chamois or
cloth will leave lint, and a brush may abrade the threads), wash
the entire soft top uniformly. Do NOT use a detergent, which may
affect the waterproofing properties of the material.
4. Rinse the whole car to prevent streaking on the paintwork. 5. Remove surface water with a sponge and allow to air dry in direct sunlight. Ensure that the roof is fully dry before stow
-
ing, as prolonged stowage of a wet or damp roof will promote
rotting of the fabric.
Keeping the soft top clean by regular washing will enhance
the life and maintain the appearance of the roof, and facilitate subsequent cleaning. The use of stronger cleansers should be left to professionals experienced in handling this type of fabric
as discoloration and degradation of the material may result.
The application of wax finishes, dressings or preservatives may cause stains, and should be avoided. Your dealer will be able to advise on current Lotus approved soft top care products.
Windscreen Cleaning When washing the windscreen, take care to lift the wiper
blade only a small distance from the glass in order not to dam
-
age the wiper arm mechanism. Wash the wiper blade with

clean water.
Alloy Road Wheels It is recommended that the aluminium alloy road wheels
are washed with the same preparation as is used to wash the bodywork. Use a brush having only nylon bristles. During the
winter months, particularly when salt has been used on the
roads for the dispersal of snow and ice, remove all the wheels,
and wash thoroughly to remove all accumulated road filth from
the wheels and Tires. Be aware that on cars fitted with optional clear anodised
forged alloy wheels (with 7 twin-spokes), the anodised surface
finish may be attacked by some proprietary wheel cleaning products. Wash only using hot soapy water or car bodywork
shampoo. Advise tire fitting companies accordingly.

Always use the size and type of tires recommended
in this handbook.
• Using incorrect tires or tires which are excessively worn or improperly inflated can cause a crash in
which you can be killed or seriously injured.
• Please note your car is not fitted with a low tire pressure tell tale lamp so it is especially important
that you regularly check the tire pressures.
When driving on wet roads, surface water is squeezed
out from between the tire and road. However excessive
speed or water depth can overwhelm the water clearing capability of the tread and lead to a condition called 'aq
-
uaplaning' or ‘hydroplaning’, where the tire rides on a film of water and provides little or no grip on the road surface,
leading to a loss of control. This condition is more likely
to occur with worn tires having little depth of tread, or with incorrect tire pressures. Drivers should keep a vigilant check on tire wear and condition, and moderate their
speed in adverse weather conditions.
Tire Care Wear indicators are moulded into the bottom of the
tread grooves at intervals around the tire, indicated by small pointers on the outer tread blocks. The tires should
be replaced before being worn to this minimum legal
tread depth. The cold tire pressures should be checked every week,
or every 1,000 miles (1,700 km), whichever is the sooner,
and corrections made as necessary. See ‘Technical Data’
at the back of the handbook for tire pressures. For track
use, tire condition and pressures should be checked be
-
fore each run. Under-inflation will cause excessive wear, rapid deterioration of the tire sidewalls and heavy steering,
whereas over-inflation results in a hard ride and increased susceptibility to tire damage. Both conditions will cause a degradation in the handling qualities. It is important that the tire pressures are adjusted only
when the Tires are cold (when the car has been standing for a minimum of 3 hours, or driven less than 1 mile), as the pressures may increase by 0.3 - 0.5 bar (4 - 8 lb/in²)
when the Tires are warmed to normal running temperature.

handling feel and minimum steering wheel shake, it is very
important that the radial and lateral run out of the Tires are to the high standard required by Lotus Cars. If any difficulty is experienced with replacement Tires, refer to
the tire manufacturer.
Tire Characteristics The Yokohama AD07 or A048 Tires fitted to the Elise
are suitable for all normal weather conditions, but are optimised for dry road sports driving. The constructions
of both tire types have been specially tailored for the
Elise and are identified by the letters ‘LTS’ moulded on the tire sidewalls. Ensure that any replacement Tires are similarly marked. The tire characteristics include good
feedback (‘feel’) from the road surface to the steering
wheel, a high level of steering linearity and response, and little performance degradation with the high temperatures
which may be reached in sports use. However, tire performance will decrease at low ambi
-
ent temperatures, resulting in reduced levels of grip and
an increased susceptibility to damage from impacts. In
these conditions, especially below 15°F (-10°C), it is recommended to fit a car set of the recommended winter
Tires (see below).
Winter Tires If the car is to be used in ver y cold territories, or
driven on snow covered roads, it is recommended to fit a

car set of winter Tires developed specifically for such
conditions. Lotus approves the use of Pirelli 210 (front)
and 240 (rear) Snowsport winter Tires in sizes specified
in ‘Technical Data’. These Tires should be fitted on regular
Elise wheels.
WARNING:
• Winter Tires are optimised for use on snow covered roads. When used on roads free of snow, winter
Tires will produce different handling characteristics and less grip compared with regular Tires.
• When winter Tires are fitted, a maximum speed of 118 mph (190 km/h) must be observed.
• Pirelli Snowsport Tires are NOT suitable for stud

ding.
Tire Chains In extreme weather conditions, Lotus approves the fit
-
ment of Pewag Neon X3 - NX373 snow chains, used only in conjunction with winter Tires (see above) and fitted only on the rear wheels. Close attention should be paid
to the fitting and tensioning instructions supplied with the chains, and the chains should be removed as soon as
road conditions allow.
Uniform Tire Quality Grading Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system de
-
veloped by the United States National Highway Traffic
Safety Administration, which grades Tires by treadwear, traction and temperature performance (This applies only
to cars sold in the United States). The grades are moulded on the sidewalls of most
passenger car Tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow
Tires, space-saver or temporary use spare Tires, Tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production Tires. While the Tires available on Lotus cars may vary with
respect to these grades, they must also conform to federal safety requirements.
Treadwear The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under controlled
conditions on a specified government test course. For example, a tire graded 150 would wear one and a half
(1.5) times as well on the government course as a tire graded 100. The relative performance of Tires depends
upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in
driving habits, service practices, and differences in road

Storing Your EliseIf you intend to store your Elise for a prolonged period, con
-
sult your Lotus dealer who will be pleased to advise you. We recommend that the car is stored inside a secure garage. The
following guidelines are provided for your information:
• Ensure the engine oil and filter, coolant and brake fluid have recently been renewed. The a.c. system should be in good
working order and fully charged.
• Thoroughly clean the inside and outside of the car, including the engine compartment. If necessary, use a ‘jet’ washer to remove dirt and salt deposits from the underside, but do not
use around bearings, hydraulic components, painted surfaces or the soft top roof. Allow to dry completely.
• Chock the road wheels, leave off the parking brake, and engage reverse gear.
• Increase the tire pressures to 60 psi (4 bar). If possible, move the car slightly every month to help avoid flat spots on the
Tires.
• Either leave the battery in the car and connect a battery management (conditioner) type of charger, or remove the battery and trickle charge every two months. Note that with
the battery disconnected or removed, the alarm system is
de-activated.
• Unless the garage is equipped with a de-humidifier, the use of drying agents (Silica-Gel) is recommended in cars with
leather upholstery and in conditions of high humidity.
• The use of unapproved car covers may have a detrimental effect on the car’s paint finish and such damage will not be
covered by your car’s warranty.
In general, the Elise will be kept in best operating condition
by regular use.
