Safety Precautions


CAUTION:
Observe the following for all installations, especially in engine compartment due to lack of room:
- Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
- Watch for sufficient clearance to all moving or hot components.
- Fuel system is under pressure. Before opening system, place rags around the connection point. Then release pressure by carefully loosening connection.


If special testing equipment is required during road test, note the following:
- Test equipment must always be secured to the rear seat and operated from there by a second person.
If test and measuring equipment is operated from the passenger seat, the person seated there could be injured in the event of an accident involving deployment of the passenger-side airbag.

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:
- Do not touch or disconnect ignition wires when engine is running or turning at starting RPM.
- Only disconnect and reconnect wires for injection and ignition system, including test leads, when ignition is turned off.
- If engine is to be cranked at starting RPM without starting.
