Traction Control Tell Tale; Abs Tell Tale; Brake Tell Tale; Oil Pressure Tell Tale - Lotus Evora Service Notes

Lotus Service Notes
Traction Control should aways be active when driving on public roads in normal conditions. To re-activate LTC,
press momentarily the LTC off switch and check that the tell tale is extinguished. For LTC details, see later.
A bulb check will light the lamp for about 3 seconds following ignition switch on.

Traction Control Tell Tale

This amber tell tale will flicker whenever the Traction Control system is triggered to indicate to the driver
that the tractive limit is being broached.
A bulb check will light the lamp for about 3 seconds following ignition switch on, but if the tell tale lights
constantly, a fault has been detected, and traction control will not be enabled.
OFF

ABS Tell Tale

OFF
A bulb check will light the lamp for about 3 seconds following ignition switch on, but if the lamp then 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 the anti-lock feature. Heavy braking, or braking on slippery surfaces
may cause one or more wheels to lock and result in reduced steering response and possible loss of control.
The car may continue to be driven with appropriate care and anticipation, but should be checked and
repaired at the earliest opportunity.
Sport Tell Tale
OFF
This tell tale will light up amber to indicate that 'Sport' mode has been selected, delivering increased throttle
response and a reduced level of traction control. This selection will default off when the ignition is next turned
on. A bulb check will light the lamp for about 3 seconds following ignition switch on.
LOTUS

Brake Tell Tale

(red)
A circuit check will light this lamp for about 3 seconds following ignition switch on. The tell tale will then
remain lit if the parking brake is applied. Check that the tell tale is extinguished when the parking brake is re-
leased, as driving the car with the brake not fully disengaged will cause overheat damage to the rear brakes.
With the parking brake released, if the tell tale should light at any time after the 3 second check period,
stop the car immediately, as the circuit has detected a dangerously low level of brake fluid in the master cylinder
reservoir, possibly caused by a hydraulic leak in one of the separate front or rear brake circuits. In the event
of a leak there is a danger that air may enter the hydraulic system and cause spongy operation and extended
pedal travel. The divided brake circuit should ensure that emergency braking remains, but the car should not
be driven until the fault has been identified and rectified.
Note that in order to inhibit false warnings of low fluid level due to surge effects, this circuit incorporates
a 10 second delay, requiring that the signal be present for a minimum of this period.

Oil Pressure Tell Tale

This red tell tale warns of low engine oil pressure. The lamp will be lit whenever the ignition is on and the
engine is stopped, but should go out as soon as the engine is started. If the lamp fails to go out after engine
start up, or comes on when the engine is running, stop the engine immediately and do not restart until the cause
has been investigated and rectified.
WARNING: Continuing to run the engine with the oil tell tale lit could cause major engine damage or
seizure, resulting in loss of car control and a crash. You or others could be killed or seriously injured.
Battery Charging Tell Tale
This red tell tale will light whenever the ignition is on and the engine is stopped. If it lights any time when
the engine is running, it indicates that the battery is not being charged, which may be due to a broken auxiliary
drive belt, or an electrical fault.
Stop the car as soon as safely possible and turn off the engine. The auxiliary belt also drives the engine
water pump, without which function the engine will overheat very quickly. If it can be determined that the
auxiliary belt and water pump are functioning correctly, 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, as this may result in engine damage and the car being stranded
in a dangerous position.
