WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Always make sure that the fuel filler cap is screwed on all the way. This helps keep fuel
from spilling out or evaporating.
x Fuel is highly flammable and explosive; it can cause severe burns and other severe
injuries.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle all the way
into the fuel filler neck can cause fuel to overflow and to spray out. Fuel spray and
overflowing fuel are dangerous because they can cause fire and serious personal injury.
x During refueling, the engine and the ignition must be switched off for safety reasons.
x Never use a cellular telephone, CB radio, or other radio equipment while refueling. The
electromagnetic radiation can cause sparks that can ignite fuel vapors and cause a fire.
x Never get back into your vehicle while refueling. If in exceptional 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. This helps avoid the
build-up of static electricity, which can cause sparks that can ignite fuel vapors released
during refueling.
x Never smoke or have an open flame (or sparks, cigarettes, or other smoldering objects)
anywhere in or near your vehicle when refueling or filling a portable fuel container.
x Follow all safety instructions and procedures that apply at the service station where you
refuel.
x Never spill fuel in the vehicle or the luggage compartment.

WARNING
Driving with a fuel tank that is almost empty can lead to stalling in traffic, a collision, and
serious personal injuries.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted,
especially when driving over bumps, across slopes, and up and down hills.
x Steering and braking assistance as well as ESC and related systems will not work if the
engine “sputters” or stalls due to lack of fuel.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel and stalling
in traffic.
NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x Never drive until the fuel tank is completely empty. The irregular fuel supply can cause the
engine to misfire. This allows unburned fuel to get into the exhaust system and damage the
catalytic converter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with
the fuel filler flap.

x Unscrew the fuel filler cap counterclockwise and remove. Place the cap on the top of the fuel filler
flap while refueling ⇒ fig. 147.
Refueling
The correct fuel grade for your vehicle is listed on a sticker on the inside of the fuel filler flap (arrow).
x The fuel tank is full when the automatic filler nozzle pump switches off the first time ⇒ .
x 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
x Screw the fuel cap clockwise onto the fuel filler neck until you hear it click into place.
x 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 severe injuries.
x 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.

The correct fuel grade for your engine is shown on a sticker located on the inside of the fuel filler flap
⇒ fig. 147.
Bad or poor quality fuel reduces operating performance, efficiency and service life of the engine. If you
notice any symptoms like rough engine idle or performance or “bucking,” immediately reduce the
vehicle speed, accelerate slowly, and keep the engine speed in the middle of the rpm range. Avoid
high rpm and rapid acceleration. If these symptoms should appear right after refueling, switch off the
engine. In both cases contact an authorized Volkswagen dealer or an authorized Volkswagen Service
Facility to have the engine checked.

WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Fuel is highly explosive and flammable and can cause severe burns and other injuries.
x Heed applicable safety warnings and obey local fuel handling regulations.
x Always make sure the fuel cap is screwed on all the way. This keeps fuel from spilling out
and from evaporating.
x 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.
x For safety reasons, the engine must be turned off when refueling.
x Never get back into your vehicle while refueling. If in exceptional 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 additives

Volkswagen recommends TOP TIER Detergent Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official Web site http://www.toptiergas.com.
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.
