| Safety precautions when working on the SCR system |
WARNING | t
| The reducing agent can irritate skin, eyes and respiratory organs. |
| t
| After skin contact with this agent, wash immediately with plenty of water. |
| t
| If necessary, call a doctor. |
|
Caution | Protect separated electrical connections against wetting from reducing agent by suitable means, e.g. plastic bag and cable ties. Electrical connections may be damaged due to the high penetration ability along with subsequent crystallisation of the reduction agent. |
|
Caution | Immediately seal all openings and connections using suitable plugs to stop ingress of dirt. The smallest particle of dirt can cause extensive damage to the system. |
|
Caution | Make sure that no reducing agent gets onto the trim panels or body components. |
| If this occurs, wash out reducing agent using clear water and a lint-free cotton cloth. |
| If the reducing agent has already crystallised, use warm water and a sponge. |
| Reduction agent that has not been removed will crystallise and damage the surface after some time. |
