● Have the necessary work carried out by a suitably qualified workshop if you are unsure how to carry out work in the bonnet space.
Volkswagen recommends using an authorised Volkswagen repairer.
● Switch on the electronic parking brake before working in the bonnet space.
● Engage the gear selector position .
● Switch off the ignition and keep the vehicle key in a safe place far enough away from the vehicle so that the engine cannot be
started accidentally.
● Never touch hot components of the engine.
● Always ensure you have not left any objects, such as cleaning cloths and tools, in the bonnet space.
● Always keep children away from the bonnet space and never leave children unsupervised.
WARNING
There are rotating parts in the bonnet space. When working in the bonnet space, particularly if the engine is started or running,
contact with rotating parts, e.g. rotor blades of the radiator fan, can cause serious or fatal injuries.
● Never reach into the radiator fan or into the area of the radiator fan even if the engine or ignition are switched off. The fan is
temperature-controlled and could start automatically.
● Before starting work, remove any jewellery and ties, tie up long hair and pull clothes in tightly.
● Always take due care and attention when depressing the accelerator. The vehicle could start moving even if the electronic parking
brake is switched on.
WARNING
Escaping hot steam or hot coolant and hot vehicle parts can cause severe burns.
● Never open or close the bonnet if steam or coolant is escaping.
● Always wait until you can no longer see or hear steam or coolant coming from the bonnet space.
WARNING
The cooling system is under pressure when the engine is hot. If the cap is opened carelessly, coolant can spray out and cause severe
burns or fatal injuries.
● Never open the cap of the coolant expansion tank when the engine is hot.
● If you have to open the cap of the coolant expansion tank, always protect your face, hands and arms from hot coolant or steam
with a large, thick cloth.
● Turn the cap of the coolant expansion tank slowly and very carefully anticlockwise while exerting slight downwards pressure on the
cap.
WARNING
Additional insulating materials, e.g. blankets in the bonnet space, or objects left in the bonnet space, e.g. cleaning cloths or tools, can
cause malfunctions, damage to the combustion engine and fire. This can result in serious or fatal injuries.
● Never cover the engine with blankets or other insulating materials.
● Never leave objects in the bonnet space.
Always park the vehicle on a horizontal and firm surface before carrying out any work in the bonnet space →
(→ Parking).
WARNING
If the vehicle is not secured against rolling away during maintenance work, unintended vehicle movement may occur. This can result
in accidents and severe or fatal injuries.
● Deactivate the start/stop system manually.
● Never work underneath a vehicle if it is not adequately secured against rolling away.
● Make sure that the vehicle is on a horizontal and firm surface and that the wheels are blocked when working under the vehicle
while the wheels are touching the ground.
● In addition, support the vehicle securely with suitable trestles when working under the vehicle. The jack is not sufficient for this
task and can fail.
