2015 VOLKSWAGEN PASSAT CC Fuel system

Never drive until the fuel tank is completely empty. The irregu-
lar fuel supply can cause the engine to misfire. This allows un-
burned fuel to get into the exhaust system and damage the cata-
lytic converter.

WARNING
Starting fluids can explode and cause a run-away vehicle condi-
tion.
Never use starting assist fluids.
NOTICE
Never use fuel with an octane rating lower than 87 AKI /
91 RON. Using lower octane fuel may cause expensive engine
damage.
Never use leaded gasoline! Leaded gasoline will severely
damage your vehicle's catalytic converter.
Methanol-blended fuels that do not meet the criteria listed
above may cause corrosion and may damage plastic and rubber
parts in the fuel system.
Never use fuels that contain lead or other metals (check listing
on the fuel pump). Even lead replacement gasoline (LRP fuels)
contain metallic additives in high concentrations. They can
damage the engine.
Do not use fuels that fail to meet the criteria above, or with
contents that cannot be identified.
If you cannot tell whether a particular fuel blend meets the cri-
teria above, ask your service station or its fuel supplier. If you
notice a loss of fuel economy or drivability and performance
problems using one of these fuel blends, we recommend that
you switch to unblended fuel.
Using fuels that are different from those specified above can
damage your vehicle's engine and fuel system and cause per-
formance problems.
Damage to the engine and fuel system and performance prob-
lems caused by using fuels that are different from those speci-
fied above or by using “starting assist fluids” are not the re-
sponsibility of Volkswagen and are not covered under the Emis-
sion warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the
catalytic converter and degrade its effectiveness in reducing polluting
emissions.

WARNING
Operating fluids and some materials in the engine compartment
can catch fire easily, causing burns and other serious personal
injuries!
Never smoke near the engine compartment.
Never work next to open flames or sparks.
Never pour or spill operating fluids or other flammable liq-
uids on the engine. These fluids can ignite on hot engine parts
and cause injuries.
If work on the fuel system or the electrical system is neces-
sary:
– 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.
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 author-
ized Volkswagen dealer or authorized Volkswagen Service Facility.
Dispose of leaked operating fluids properly.

Government regulations in the United States and Canada require that
automobiles meet specific emission regulations and safety standards.
Therefore, vehicles built for the U.S. and Canada differ from vehicles
sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that:
Unleaded fuels for vehicles with catalytic converters may not be
available.
Fuel may have a considerably lower octane rating and may cause
engine damage.
Service may be inadequate due to lack of proper service facilities,
tools or testing equipment.
Replacement parts may not be readily available.
DVD navigation systems for vehicles built for the United States and
Canada will not necessarily work in Europe, and may not work in oth-
er countries outside of North America.

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:
Traffic suddenly slows down or stops in front of you to warn those
approaching from behind.
In any emergency situation.
If the vehicle breaks down.
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.
Always review and follow the checklist. Follow accepted safe-
ty practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter get very
hot. They can cause fires and serious personal injury.
Never park where parts of the hot exhaust system or catalytic
converter could ignite flammable materials, such as dry grass,
brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are
on for a long time – even if the ignition is switched off.

WARNING
Improper use of jumper cables when jump-starting a vehicle
with a dead battery can cause the battery to explode, leading to
serious personal injury. To help reduce the risk of battery ex-
plosion:
All work on the batteries or the electrical system in your ve-
hicle can cause serious acid burns, fires, or electrical shocks.
Always read and heed the following WARNINGS and safety pre-
cautions before working on the batteries or the electrical sys-
tem ⇒  Vehicle battery.
Always make sure that the battery providing starting assis-
tance (the booster battery) has the same voltage as the dead
battery (12 V) and about the same amperage capacity (see bat-
tery label).
Never jump-start a vehicle with a thawed or frozen vehicle
battery. The battery can explode. A dead battery can freeze at
temperatures around +32 °F (0 °C).
A battery that is frozen or was frozen, but has since thawed,
must be replaced.
When the vehicle battery is jump-started, it gives off hydro-
gen gas, which is highly explosive! Always keep fire, sparks,
open flame, and smoking materials far away from vehicle bat-
teries. Never use a mobile telephone while connecting or dis-
connecting jumper cables.
Jump-start batteries only in well-ventilated areas. Batteries
give off highly explosive hydrogen gas during jump-starting.
Always route the jumper cables so that they cannot get
caught in any moving parts in the engine compartment.
Never short out the battery terminals by connecting the posi-
tive (+) and negative (-) terminals with each other.
Never connect the negative cable from the other vehicle di-
rectly to the negative terminal of the dead battery, as this may
cause the hydrogen gas given off by the dead battery to ex-
plode.
Never attach the negative cable from the vehicle providing
starting assistance to any part of the fuel system or to the
brake hoses or brake lines.
