radiator cap VOLKSWAGEN TRANSPORTER 2020 Owners Manual

A WARNING (Continued)
-Remove the vehicle key from the igni-tion lock.
-Always keep children away from the en-gine compartment and never leave the ve-hicle unattended.
• The engine cooling system Is under pres-sure when the engine Is hot. Never open the cap of the coolant expansion tank when the engine Is hot. Coolant may spray out and cause serious burns and other Injuries.
-Turn the cap slowly and very carefully anti-clockwise while exerting gentle down-ward pressure on the cap.
-Always protect the face, hands and arms from hot coolant or steam with a large, thick cloth.
• When refilling, do not spill any service flu-ids on engine components or on the exhaust system. The spilt service fluids can start a fire.
A WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries and death!
• Never short circuit the electric system. The vehicle battery could explode.
• Please note the following guidelines to help reduce the risk of an electric shock and serious Injuries while the engine is running or being started:
-Never touch the electrical wiring of the Ignition system.
A WARNING
There are rotating components in the engine compartment that can cause serious injury.
• Never place your hand near these compo-nents or In the radiator fan. Touching the ro-tary blades can result in serious injuries. The fan Is temperature-controlled and can start automatically, even if the engine has been switched off and the vehicle key has been re-moved from the ignition lock.
• If any work has to be performed when the engine Is started or with the engine running, there is an additional, potentially fatal, safety risk from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always be particularly careful.
A WARNING (Continued)
-Always ensure that no body parts, jew-ellery, ties, loose items of clothing or long hair can be caught up in rotating engine components. Before starting work, re-move any jewellery and ties, tie up long hair and pull clothes In tightly to avoid them getting caught In the engine com-partment.
-Always depress the accelerator careful-ly and never without due consideration. The vehicle can start to move even if the handbrake is applied.
• Always ensure that you have not left any objects, such as cleaning cloths and tools, in the engine compartment. Any forgotten items can cause malfunctions, engine damage and fires.
A WARNING
Additional insulating materials such as cov-ers in the engine compartment could disrupt the operation of the engine, cause damage and lead to severe Injuries.
• Never cover the engine with any Insulating materials.
A WARNING
Service fluids and some materials In the en-glne compartment are highly flammable and can cause fires and serious Injuries!
• Never smoke while working on the vehl-cl e.
• Never work near naked flames or sparks .
• Never spill fluids onto the engine. They could Ignite on hot engine components and hence cause injuries.
• Please note the following when carrying out any work on the fuel system or the elec-trlcal system:
-Always disconnect the vehicle battery. Ensure that the vehicle Is unlocked when the vehicle battery Is disconnected as oth-erwlse the anti-theft alarm will be activa-ted.
-Never work in the direct proximity of heating systems, water heaters or any oth-er open flames.
• Always have a fully functional and tested fire extinguisher to hand.

If you notice misfiring, uneven running or loss of power when the vehicle is moving, reduce speed Immediately. The vehicle should be inspected at
Diesel particulate filter
r-f'n First read and observe the Introductory L-J,:,.IJ Information and safety warnings & on page 407.
The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles gather in the filter and are burnt under high temperatures peri-odically (regeneration). Heat produced can warm the engine.
Regeneration can cause noises, light smells and delay in radiator fan irrespective of the outside temperature, even after the engine is switched off.
To assist the regeneration of diesel particle filter, Volkswagen recommends that you avoid making only short journeys. In vehicles with a DSG® dual clutch gearbox the engine speed can increase while the vehicle is being driven. However, the indi-cator lamp • will not light up.
Observe the following points to ensure that the ex-haust system and the diesel particulate filter will work properly for a long time:
the nearest qualified workshop. If this happens, un-bumt fuel can enter the exhaust system and es-cape into the atmosphere. The catalytic converter can also be damaged by overheating.
Even when the exhaust purification system is W working perfectly, there may be a smell of sulphur from the exhaust in some conditions. This depends on the sulphur content of the fuel being used. <1
• Only use diesel with low sulphur levels 343.
• Never use biodiesel, petrol or heating oil.
• Do not allow the fuel tank to run empty.
• Do not overfill engine oil 353.
• Do not tow-start the vehicle. Use jump leads =page 443.
