fuel VOLKSWAGEN CC 2008 Service Manual

When the ignition is switched on, several warning and indicator lights
come on briefly for a function check. They go out after a few seconds.
Fuel filler cap not properly closed

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.
The small arrow next to the gas pump symbol in the fuel gauge
⇒ fig. 160 shows the side of the vehicle with the fuel filler flap.
Refueling

Fig. 161 In driver door: Release switch for fuel filler flap.

Fig. 162 Fuel cap placed on the open fuel filler flap.

Opening the fuel filler cap
Pull the release switch  in the driver door upwards ⇒ fig. 161.
The fuel filler flap is on the right rear side of the vehicle.
Open the fuel filler flap.
Unscrew the fuel cap counterclockwise and remove. Use the slot or
the upper edge of the fuel filler flap to hold the cap while refueling
⇒ fig. 162.
Refueling
The correct fuel grade for your vehicle ⇒  Fuel is listed on a sticker on
the inside of the fuel filler flap ⇒ fig. 162 (arrow).
The fuel tank is full when the automatic filler nozzle pump switches
off the first time ⇒ .
Do not try to add fuel after the pump stops! Topping off the tank in
this way may fill the expansion space that the tank needs and cause
fuel to overflow, for example, if it gets warmer outside.
Closing the fuel filler cap
Screw the fuel cap clockwise onto the fuel filler neck until you hear
it click into place.
Close the fuel filler flap until you hear it latch shut. The fuel filler
flap must be flush with the vehicle body.
WARNING
Spilled fuel can cause fires, explosions, burns, and other se-
vere injuries.
Always stop refueling once the pump nozzle switches off so
that the tank does not overflow.
NOTICE
Remove fuel spills from all vehicle surfaces immediately to help
prevent damage to the paint, tires, and wheel housings.
Fuel spills may pollute the environment.

WARNING
Improper refueling or handling of fuel can cause fire, explosion,
and severe burns.
Fuel is highly explosive and flammable and can cause severe
burns and other injuries.
Heed applicable safety warnings and obey local fuel handling
regulations.
Always make sure the fuel cap is screwed on all the way. This
keeps fuel from spilling out and from evaporating.
Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the vehicle's filler neck could cause
fuel overflow and fuel spray. Fuel spray and overflowing fuel
are dangerous because they can cause fire or serious injury.
For safety reasons, the engine must be turned off when refu-
eling.
Never get back into your vehicle while refueling. If in excep-
tional circumstances you must get back in your vehicle while
refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle
again. Static electricity can cause sparks that can ignite fuel
vapors released during refueling.
Gasoline

TOP TIER Detergent Gasoline, please go to the official Web site,
http://www.toptiergas.com.
The gasoline grades most commonly sold in the United States and
Canada have the following octane ratings, which can usually be found
on the filler pump:
Premium grade: 91 to 96 AKI
Regular grade: 87 to 90 AKI
Unleaded gasoline
Unleaded gasoline is available throughout the USA and Canada.
Volkswagen recommends that you do not take your vehicle to places
where unleaded gasoline may not be available.
Gasoline containing alcohol or MTBE
You may use unleaded gasoline blended with alcohol or MTBE (me-
thyl tertiary butyl ether), commonly referred to as oxygenated fuels, if
the blended mixture meets the following criteria:
Blends of gasoline and methanol (wood alcohol or methyl alco-
hol):
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 3% methanol.
Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 15% ethanol.
Blends of gasoline and MTBE:
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 15% MTBE.
Seasonally adjusted gasoline
Many fuels are blended especially for winter or summer conditions.
When seasons change, Volkswagen suggests that you buy fuel at
busy stations where the seasonal adjustment is more likely to be
made earlier.

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.

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. Never use fuel line antifreeze offered for
gasoline engines.
Gasoline additives

If you must fuel your vehicle with gasoline whose octane rat-
ing 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.
Do not use fuel that is labeled at the pump as containing met-
al. Lead replacement fuel contains high concentrations of metal-
lic additives. Engine damage could result.
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.
