2013 VOLKSWAGEN JETTA HYBRID engine

If quality gasoline with additives that do not contain metal is not available or engine malfunctions
occur, you should add the required additives while refueling ⇒ .
Not all gasoline additives are effective. Using the wrong additives can cause significant and expensive
damage to the engine and the catalytic converter. Never use additives that contain metal. Please note
that metal can be included in some aftermarket gasoline additives that are available to be added to
gasoline during or after refueling to help improve knock resistance or increase the octane rating.
Volkswagen recommends using only additives approved by Volkswagen. Appropriate additives as well
as instructions on how to use them are available from your authorized Volkswagen dealer or
authorized Volkswagen Service Facility. Do not add any other gasoline additives.
NOTICE
You can damage the engine by using incorrect additives.
x Using incorrect gasoline additives can cause extensive engine damage as well as damage
to the catalytic converter.
x If you must fuel your vehicle with gasoline whose octane rating is too low, only drive with
the engine speed in the middle of the rpm range and with low engine load. Avoid high rpm and
heavy engine load. Otherwise, the engine could be damaged. Refuel your vehicle with gasoline
with the required octane rating as soon as possible.
x Do not use fuel that is labeled at the pump as containing metal. Lead replacement fuel
contains high concentrations of metallic additives. Engine damage could result.
x Fueling your vehicle just one time with leaded fuel or fuel that contains other metallic
additives can affect the performance of the catalytic converter and cause extensive damage to
it.

Preparations for working in the engine compartment

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).
– 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.
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!
x Never short-circuit the electrical system. Be especially careful when using jumper cables.
The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or
being started:
– Never touch ignition cables. Never touch other components of the high voltage
electronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine
compartment or! Bookmark not defined., Cleaning the engine compartment

WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can
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.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing
burns and other serious personal injuries!
x Never smoke near the engine compartment.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids
can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when
you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the
ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct
reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and
engine damage.
Fluid leaks and spills are harmful to the environment. Regularly check the ground underneath
your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your
authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating
fluids properly.
