WF.6 - SAFETY PRECAUTIONS, SHIPPING, STORAGE & DISPOSAL
WARNING: The SDM can maintain sufficient voltage to cause an airbag deployment for up to 20 seconds
after the battery has been disconnected. Before working on the airbag system, or in close proximity to
an airbag, first take the following precautions to temporarily disable the airbag system:
1. Turn off the ignition.
2. Before disconnecting the battery, use the Lotus TechCentre to read any stored trouble codes.
3. Disconnect the negative (earth) lead from the battery and tape back to ensure that no contact with the
battery negative terminal can be made.
4. Wait for 30 seconds.
5. If working on or near the steering wheel, first unclip the top part of the column shroud, then remove the
lower part after releasing the three retaining screws.
6. Locate and unplug the airbag harness from the rotary connector. Note that the connector socket is fitted
with 'shorting bars' which automatically interconnect the high and low terminals of the airbag to prevent
unschedules deployment caused by a voltage differential.
When service work has been completed, reconnect the harness plug secured with its locking feature, and
reconnect the battery. Ensure the airbag tell tale lights for a few seconds with ignition and then goes out.
Storage
- Airbag modules and SDMs should not be stored at temperatures above 176°F (80°C).
- Airbag modules and SDMs should not be stored in damp conditions.
- Do not store airbag module or SDM boxes more than two high.
- Always store and handle airbag modules and SDMs in an upright position. Never store SDMs upside
down.
Sensor & Diagnostic Module (SDM) & Forward Crash Sensors
The SDM and forward crash sensors are calibrated specifically to the Evora, and are mounted in a
dedicated manner in specific positions. Never use SRS components from any other vehicle, or modify their
mounting to the Evora.
WARNING:
• Handle the SDM with great care. Never strike or jar the SDM as this could cause airbag deployment
and result in personal injury or improper operation of the SRS.
• All module and mounting bracket bolts must be correctly installed and tightened to assure proper
security and operation.
• Never power up the SRS when the SDM is not properly mounted and secured, since the SDM is
easily triggered when not attached, and could result in deployment causing personal injury.
• Do not use or attempt to repair a damaged SDM.

Inflator Module

Live (Undeployed) Inflator Modules: Special care is necessary when handling and storing a live (undeployed)
inflator module. In the unlikely event of accidental deployment, violent movement of the inflator module could
result in personal injury.
WARNING:
• When carrying a live inflator module, make sure the bag and trim cover are pointed away from you.
In case of an accidental deployment, the bag will then deploy with minimal chance of injury.
• When placing a live inflator module on a bench or other surface, always face the bag and trim cover
upwards, away from the surface. This is necessary so that a free space is provided to allow the
air bag to expand in the unlikely event of accidental deployment. Otherwise, personal injury may
result.
• Never carry the inflator module by the wires or connector on the underside of the module.
