HI.3 - PAS FLUID CHECK & REFILL PROCEDURE
Recommended fluid: PAS or Automatic Transmission Fluid meeting Dexron III
Capacity: 1.5 litre
Fluid Level Check
The PAS fluid reservoir is located at the right hand rear corner of the engine bay with the fluid level visible
through the translucent material of the reservoir. The level of fluid will rise as the oil temperature warms during
normal operation, and the best time to check the level (part of each routine service) is with the engine warm,
immediately after a run. With a warm engine, the level should be close to the 'MAX' mark, and if cold, close
to the 'MIN'. Note that there are two sets of marks on the reservoir, with hot markings on the outboard side,
and cold marks in the inboard side, the hot marks being at a slightly higher level. The fluid level will also drop
slightly when the engine is running.
Under normal circumstances, the PAS fluid should not require any topping up, and a drop in level is likely
to be an indication of a leak.
If topping up is required, the air outlet grille at the RH rear corner of the engine bay must first be removed
by releasing its two retaining screws. The reservoir cap may then be removed and a suitable funnel used to
aid the addition of an approved fluid. Do not overfill. Replace the cap securely, and refit the grille.
Fluid Change & Bleeding
In the normal course of operation, it is not necessary to change the hydraulic fluid, only to check the level.
If, however, the system becomes contaminated with dirt or other fluids, all pipework connections should be
released and fluid expelled using low pressure air. Dispel fluid from the rack mechanism by turning the steering
to each full lock. Dispel fluid from the pump by cranking the engine for a few moments with ignition disabled.
After draining the fluid, or after the loss of fluid during the course of repairs or hydraulic system discon-
nection;
- Fill the reservoir with an approved fluid.
- Raise the front of the car and turn the steering wheel slowly from lock to lock several times. Top up fluid
level if necessary.
- Lower the car, start the engine and idle for a few minutes, before turning the steering to full lock and hold-
ing for 3 seconds, then repeating for the opposite lock. Repeat this sequence several times.
- Stop the engine and check the reservoir level.
- Any foaming or emulsification of the oil is an indication of air in the system. Repeat the above procedure.
If symptoms persist, check for air/fluid leaks.
HI.4 - STEERING WHEEL
The alloy three spoke steering wheel features a flattened lower section to facilitate driver access, a leather
trimmed rim, buttons for the cruise control (if fitted) and an airbag module which also serves as a press pad
to operate the horns. The electrical supply for the steering wheel mounted equipment utilises a rotary coil as-
sembly surrounding the column.
The wheel comprises a cast magnesium rim and spokes, to which is bolted a machined alloy hub, with a
screw fixed alloy pressing to carry, via double sided tape, the cruise control buttons and/or trim.
To Remove Steering Wheel
WARNING: The following procedures must be followed in the order listed to temporarily disable the
airbag system whilst working in the immediate vicinity of an airbag. Failure to follow this procedure
could cause unintended airbag deployment, resulting in personal injury and unnecessary airbag sys-
tem repairs.
i) Turn off the ignition.
ii) Before disconnecting the battery, use the Lotus TechCentre to read any stored trouble codes.
iii) Disconnect the negative (earth) lead from the battery and tape back to ensure that no contact with the
battery negative terminal can be made.
iv) Wait for 30 seconds.
