affected by it done by qualified, trained technicians who have the know-how, experience,
documentation, and tools to do the work safely.
x All work on the high-voltage electrical system and the high-voltage battery must be done
in compliance with Volkswagen standards and guidelines.
x Vehicle keys must be safely stored a safe distance from vehicle so that the ignition cannot
be switched on and energize the electrical system.
x Gases vented or released from the high-voltage battery vapors are potentially poisonous
and can burn.
x Physical damage to the vehicle or the high-voltage battery can result in immediate or
delayed release of poisonous gases that can also cause a fire.
x Always avoid contact with leaking fluids and gases escaping from the battery, particularly
one that has been damaged.
x Always tell emergency responders that the vehicle has a high-voltage battery.
WARNING
Unintended vehicle movement during maintenance work can cause serious personal injuries.
x Never work under the vehicle unless you have safely secured the vehicle from moving. If
you must work under the vehicle with the wheels on the ground, always make sure that the
vehicle is on level ground, that all 4 wheels are chocked to keep them from moving, and that
the key is not in the ignition.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle
is safely supported on safety stands intended for that purpose that are strong enough to
support the weight of the vehicle. The jack supplied with the vehicle is not strong enough for
this purpose and can collapse causing serious personal injury.

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).

– 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.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot
parts of the engine or exhaust system can cause a fire.
WARNING
High voltage systems in the engine compartment can cause electrical shocks or even
electrocution, severe burns, other serious injuries, and even death!

cause serious personal injury. Always remember that the radiator fan is temperature-
controlled and can come on suddenly even when the engine has been switched off for a while
and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks
from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the
high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in
rotating engine parts. Before starting any work remove your jewelry, take off your necktie,
tie back and cover your hair, and do not wear clothing that can hang down and get caught
in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a
check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools.
Objects left behind can cause malfunctions, engine damage, and even fires.
