WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause
serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always
follow commonly accepted safety practices and use common sense. Never risk personal
injury.
x Never perform any work in the engine compartment unless you know exactly how to carry
out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician. Serious personal injury may
result from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant
can cause serious burns. Always wait until you no longer see or hear steam or coolant
escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or
Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out
of range of the vehicle and that the vehicle cannot be started by depressing the starter
button .
– Always keep children and others away from the engine compartment and never leave
them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the
coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause
severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying
light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by
covering the cap with a large, thick rag.

7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.

If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for
example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to
alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common
sense.

WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot.
