Safety precautions

2002 Volkswagen Golf GLS, 2.0 K, StandardSECTION Safety precautions
WARNING: This page is about a different variant/trim than selected.
WARNING:

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, 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.

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 glow plug system, always observe the following:

  • Only disconnect and reconnect wires for glow plug and fuel injection systems, including test leads, when ignition is turned off.
