properly restrained. Children, and short adults are at the great-
est risk. Be sure to follow all instructions and warnings in the handbook (See page 21 to 27).
Don’t Drink and Drive Alcohol and driving don’t mix. Even one drink can reduce your
ability to respond to changing conditions, and your reaction time
gets worse with every additional drink. So don’t drink and drive,
and don’t let your friends drink and drive, either.
Control Your Speed Excessive speed is a major factor in crash injuries and deaths.
Generally, the higher the speed the greater the risk, but serious accidents can also occur at lower speeds. Never drive faster
than is safe for current conditions, regardless of the maximum speed posted.
Keep Your Car in Safe Condition Having a tire blowout or a mechanical failure can be extremely
hazardous. To reduce the possibility of such problems, check
your tire pressures and condition frequently, and perform all
regularly scheduled maintenance (see separate Maintenance
Record booklet).

CAR IDENTIFICATIONThe Vehicle Identification Number (V.I.N.) is a unique 17-digit
number used to identify the car for warranty, spares order
-
ing and administrative purposes. For reference, the number may be viewed from outside the car at the left hand bottom
corner of the windscreen. The number is also printed on

a label stuck to the inside of the chassis sideframe alongside
the driver’s seat. It is repeated on the certification label on the
driver’s door jamb. This label contains tire pressure information.
The chassis frame is stamped with the V.I.N. in the right hand front wheelarch area, viewable with the front wheels turned to right full lock.
It is essential that the complete V.I.N. is quoted in any corre
-
spondence concerning the car, or when ordering spare parts.

Note that the tell tale also functions as a high engine speed
(rpm) warning - see ‘Tachometer’.
NOTICE: The car is not fitted with a low pressure tell tale. You should check the tire condition and pressure regularly. See

stopping distance, a locked wheel provides little or no steering
force, such that with both front wheels locked, movement of the steering wheel has no effect on car direction. With the anti-lock
system, even panic braking results in controlled deceleration and the retention of steering response. ABS is especially ad
-
vantageous when braking on slippery road surfaces and in bad driving conditions, but it is important to realise that the ABS
cannot increase the friction level at the road surface, but can only make optimum use of the grip available.
WARNING: When driving in adverse weather, or on poor road sur
-
faces, always be alert to the possibility of slippery condi
-
tions and make the necessary allowance for increased stop
-
ping distances. Failure to do so may result in an accident in which you or others may be killed or seriously injured.
Normal braking, controlled by the pressure applied to the
brake pedal, occurs when the road conditions allow for decel
-
eration to be achieved without danger of wheel lock. The relative
speeds of the four wheels are continuously monitored by the
ABS when the brakes are applied, and if one or more wheels begin to lock, the brake pressure to that wheel(s) is modulated
by the ABS to help keep the wheel rotating and provide the
maximum controlled braking force. The wheels may appear
to lock momentarily as the wheel speed rapidly changes, and some tire noise (intermittent screeching) may be heard which is normal and will vary with road and tire conditions. Note that the
ABS does not function at speeds below 5 mph (7 km/h). When the ABS is activated, the driver is will feel a ‘pulsing’
sensation at the brake pedal as the fluid pressure is modulated, and also by audible clicking sounds. These signals indicate to
the driver that maximum braking is occuring, and that driving style should be modified to suit the conditions.
The minimum stopping distance is achieved by applying the
brakes firmly and steadily, and allowing the ABS to modulate
hydraulic pressure. The driver should not attempt to emulate
this process by ‘pumping’ the brake pedal, as modulation at the pedal will treat all four wheels similarly, rather than the individual
wheel control allowed by the electronics. An ABS tell tale lamp in the instrument panel is provided
to warn of any problems in the system and to indicate that the

integral self diagnostics have switched out the anti-lock function.
See ‘ABS tell tale lamp’.
WARNING:
• The increased control that ABS provides should not induce you to take more risks with your safety. ABS will
not prevent a skid caused by abrupt steering movements,
or attempting to corner too quickly.
• Always maintain a safe following distance from other cars relative to the road surface and weather conditions.
Obey all traffic laws.
• Risk of accidents due to inappropriate speed cannot be reduced even by ABS. The driver is responsible for the
judgement of safe speed.
• The control unit of the ABS is set for standard tire size. If non-standard Tires are fitted, the control unit may mis-
interpret the speed of the car, because of the variant data
it receives from the wheel speed sensors. Fitting non standard tires would seriously affect the performance of
your ABS.
• The amber ABS tell tale in the instrument panel should light for about 4 seconds following ignition switch on, and
then go out. If the lamp remains lit, or comes on whilst driving, a fault in the anti-lock brake system is indicated.
The base brake system will continue to operate normally,
but without ABS. The car can be driven but should be
checked and repaired at the earliest opportunity.
• Activation of the ABS will vary according to the level of grip available at the Tires. On dry surfaces, activation
will occur only with a high pedal pressure. On slippery
surfaces, only a low pressure will be needed.
• On loose or uneven surfaces, such as gravel or snow, a car with ABS may need a longer stopping distance. Allow
a greater distance between cars in these conditions.

TIRES AND WHEELS
TiresGlossary of Terms:Recommended inflation pressure: The cold tire inflation pressure which is recommended for this car and is speci
-
fied in the ‘Technical Data’ section of this handbook.
Cold tire inflation pressure: All tires must be cold, meaning
that the car has been stationary for a minimum of 3 hours, or has been driven less than 1 mile. Adjust pressures only
in ambient conditions.
Maximum inflation pressure: The maximum inflation pres
-
sure to which the tire should be subjected. For the Elise,
use only the recommended inflation pressure.
Lotus engineers have worked with tire manufacturers
to produce tire specifications for the Elise which optimise performance on both road and track. To ensure that any
replacement tires are to the correct Lotus specification,
always refer to your Lotus dealer, who will have the latest recommendations.
WARNING: In order to achieve the optimum handling char
-
acteristics, the wheel and tire sizes on the Elise are different front and rear. This means that interchanging
of wheels and tires between axles is not permissible.
Failure to adhere to this requirement will adversely affect the handling of the car and may result in an
accident in which you or others could be killed or seriously injured,
The tires should be regularly inspected for signs of cuts,
abrasions or other damage, and for any uneven tread
wear patterns. Uneven treadwear may indicate that the suspension geometry or dampers require attention from
your dealer.

NOTICE:
• On cars used on a race track or in a competitive manner,
special vigilance is required due to the severity of tire operating conditions, with careful inspections carried
out between sessions.
• Take care when parking to avoid tire contact with high
or sharp edged kerbs. Such mistreatment can cause
internal damage to the tire structure and this may not be readily apparent. The wheel rims may also be distorted or damaged by careless parking, and result in wheel
imbalance or loss of tire pressure. Similar damage may also be caused by potholes, rocks or other highway
debris.
WARNING:
• Damage to wheels and tires may cause an accident in which you or others may be killed or seriously
injured. If the wheels or tires have been damaged,
have them replaced.
• Safety considerations should always be paramount when assessing tire condition and serviceability, and the tires replaced if any doubt exists, or if the
legal tread depth limits are approached.
• Poorly maintained and improperly used tires are dangerous.
• Overloading your tires can cause overheating as a result of too much friction. You could have a blow
out and a serious accident in which you could be killed or seriously injured. See ‘Tire Placard La
-
bel’.
• Underinflated tires pose the same danger as over loaded tires. The resulting accident could cause serious injury, or death. Check all tires frequently
and maintain at the recommended pressure. Tire
pressures should be checked only when the tires
are cold.
• Overinflated tires are more likely to be cut, punc- tured or broken by a sudden impact - such as hitting a pothole. Keep tires at the recommended pressure.
• Installing improper tires on your car can affect handling and stability. This can cause a crash
in which you can be killed or seriously injured.

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.

Use a good quality proprietary tire pressure gauge and always replace the tire valve dust cap to prevent the
ingress of dirt and moisture into the valve, which could cause leakage. Many fuel filling stations provide tire inflation facilities,
which specific usage instructions should be carefully fol
-
lowed. For tire pressure information, refer to ‘Technical
Data’ or the Certification Label on the driver’s door jamb
(see page 121).
Replacement Tires When replacing tires, refer to the ‘Technical Data’ sec
-
tion in this handbook, or consult your dealer to check the current Lotus specification and recommendations. Do not
use tires which differ from these specifications.
WARNING: Note that some tread patterns are directional, so
that the tire must be fitted onto the wheel with regard
to which side of the car the wheel is to be used. In
these cases, a direction of rotation arrow is included in the tire sidewall markings.
When balancing the wheel and tire assemblies, the
wheels should be located by the centre spigot hole - NOT by the wheel bolt holes. In order to maintain the correct

Directions for use of the aerosol: Before using, carefully read all the instructions on the canister, or on any literature
accompanying the product. The following instructions ap
-
ply to the use of Holts Tireweld:
1. Remove the object causing the puncture, and position the wheel with the puncture site lowermost. Deflate tire
fully.
2. Shake the can vigorously. In cold conditions, warm the
can using the car's heater outlets, or by body warmth.
3. Screw the aerosol tube onto the tire valve, remove the cap, hold the can upright and press the button until the
tire is firmly inflated.
4. Immediately drive for 6 - 12 miles (10 - 20 km) (or to the tire repair facility if nearer) in a moderate manner and not exceeding 30 mph (45 km/h), to allow the sealant
to spread. Then check and adjust the tire pressure as necessary.
5. Have the tire professionally repaired or replaced at the earliest opportunity, and until such time, limit speed to
30 mph (45 km/h) with a moderate driving manner. Note that some tire repairers may make an additional charge
for cleaning the sealant off the tire before repair, and
that any subsequent repairs may not be guaranteed.
6. Renew the puncture repair aerosol.
