RUNNING-IN
Running-In
Running-in (or bedding-in) of a new engine
and transmission contributes to achieving
the highest levels of efficiency, durability,
smooth operation and performance. By
following the simple guidelines described,
a solid foundation will be built for the car's
lifetime use.

Engine

It is important during the car's early life,
not to overload the engine and to control
the amount of engine heat generated. This
is dependent primarily on throttle opening
(accelerator position) and engine speed.
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 4,000 rpm. Occasional
short bursts at wider throttle and higher
engine speed will be beneficial, as will a
constantly changing cruising speed and
making full use of the gearbox. Do not
allow the engine to labour in too high a
gear ratio; change down and let the engine
operate in its natural power band.

After 600 miles (1,000 km) have been
covered, full throttle and/or maximum
engine speed may be used for short
periods, but do not attempt to exploit full
vehicle performance until after the first
'After Sales' service has been carried out.

Transmission

Use a light touch to guide the gear lever.
Forcing the change will cause unnecessary
wear on system components and impair
subsequent gearchange quality.

Brakes

Allow the brakes to bed-in by avoiding
needless heavy braking for the first 100
miles (160 km). Thereafter, the first time
the brakes are used aggressively, some
loss of brake feel may be evident as the
brake pads undergo a final conditioning
phase. After the brakes have cooled, full
brake performance will be restored. Both
the brake pedal and gearchange efforts
are likely to reduce during the running-in
period.

Tires

New tires also require a short 'running-in'
period before providing optimum grip.

Stopping the Engine

After running the engine at high speed
or under heavy load and generating
substantial engine heat, if possible before
switching off the engine, drive for a short
period in a gentler manner, or allow the
engine to idle for a few minutes in order
for normal temperatures to be resumed.
This will reduce the effects of heat soak
and benefit the long term durability of the
powertrain.

Engine Data Recording

Note that various operating parameters
are continuously monitored and recorded
in the engine electronic controller. This
data may be downloaded by Lotus dealers
on demand in order to assist with fault
diagnosis.
NOTICE: Failure to comply with the
running-in provisions could invalidate
the terms of the New Vehicle Warranty.
