Volkswagen Golf Service & Repair Manual: Safety precautions for working on vehicles with auxiliary/supplementary
heater
| Danger of fire and explosion from auxiliary/supplementary heater |
| In fire and explosion-endangered areas a spark or the high
temperature of the auxiliary/supplementary heater can cause a fire or an
explosion. Burn injuries are also possible. |
| – |
Switch the auxiliary/supplementary heater off in fire and
explosion-endangered areas. |
| Danger of poisoning from exhaust fumes |
| Auxiliary/supplementary heaters produce poisonous exhaust fumes.
Injuries to airways and poisoning are possible. |
| – |
In closed areas, only switch on the auxiliary/supplementary heated
when it is exclusively connected to an exhaust extractor system. |
| – |
In closed areas without an exhaust extractor system, switch off the
auxiliary/supplementary heater. |
| Danger of damage when starting the engine. |
| If the fuel system components (e.g. metering pump, fuel lines, fuel
gauge sender) are removed or opened, there is a possibility of causing
damage to the auxiliary/supplementary heater. |
| – |
Never attempt to start the engine when fuel system components are
removed or opened. |
| Malfunctions caused by air in the fuel system |
| After working on the fuel tank or the fuel delivery pump the
metering pump will draw air and supply it to the auxiliary/supplementary
heater. The air in the fuel system may cause the auxiliary/supplementary
heater to malfunction. |
| – |
Fill the fuel take-off pipe with fuel. |
| Risk of accidents and risk of injury due to activated timer of
auxiliary heater |
| On vehicles with activated timer for the auxiliary heater, the
auxiliary heater may be switched on unexpectedly. This poses a risk of
poisoning from exhaust gases, a risk of burns caused by hot auxiliary
heater components as well as a risk of fire and explosions caused by
high temperatures. |
| – |
Deactivate timer for auxiliary heater. |
Risk of scalding by hot coolant
When the engine is warm, the cooling system is under pressure.
Danger of scalding due to steam and hot coolant.
