Safety notes on working in the engine compartment
The engine compartment of a motor vehicle is a hazardous area. You should only carry out work on the engine and in
the engine compartment if you know exactly how to perform the required tasks, are aware of the general safety
procedures and have access to the correct equipment, service fluids and suitable tools. Carrying out work incorrectly
can cause serious injuries. The work should be carried out by a qualified workshop if you are uncertain. Volkswagen
Commercial Vehicles recommends using a Volkswagen Commercial Vehicles dealership for this purpose.
Always park the vehicle on a level and stable surface before carrying out any work in the engine compartment.
WARNING
Unintentional vehicle movements during service work can cause serious injury.
● Never work underneath a vehicle if it is not secured against rolling away. If you are working underneath the
vehicle while the wheels are on the ground, the vehicle must be on a level surface, the wheels must be blocked
and the ignition switched off.
● If you have to work underneath the vehicle, use suitable stands to provide extra support for the vehicle. The
vehicle jack is not sufficient for this task and can fail, which can lead to serious injuries.
● The start/stop system must be manually deactivated.
WARNING
The engine/motor compartment of any motor vehicle is a dangerous area. Serious injuries can be sustained here.
● The utmost care and attention must be paid when carrying out any work and you must follow the general safety
rules. Never take any risks.
● Never do any work on the engine or in the engine compartment unless you know exactly how to carry it out. If
you are uncertain of what to do, the work should be carried out by a qualified workshop. Serious injuries can
result from work that has not been carried out properly.
● Never open the bonnet if you see steam or coolant escaping from the front compartment. Hot steam or hot
coolant can cause serious burns. Always wait until you can no longer see or hear steam or coolant coming from
the engine compartment.
● Always allow the engine to cool down before opening the bonnet.
● Hot parts of the engine or exhaust system can burn the skin.
● Observe the following points before opening the bonnet when the engine has cooled down:
● Switch on the electronic parking brake and move the selector lever to positionP or move the manual gear lever
to the neutral position.
● Switch off the ignition.
● Always keep children away from the engine compartment and never leave unsupervised.
● The cooling system is under pressure 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.
● Slowly and carefully turn the cap on the coolant expansion tank anti-clockwise while exerting gentle
downward 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 fluids on engine components or on the exhaust system. The spilt service
fluids can start a fire.
WARNING
There are rotating components in the engine compartment that can cause serious injury.
● Never reach into the radiator fan or into the area of the radiator fan. Touching the rotary blades can result in
serious injuries. The fan is temperature-controlled and could start automatically - even when the ignition is
switched off.
● 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 poly V-belt, alternator, radiator fan, etc., and
from the high-voltage ignition system. Always be particularly careful.
