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.

Refueling
Engine control and exhaust system

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 refueling.
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

Please first read and note the introductory information and heed the WARNINGS

Octane rating

Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition.
Using the correct grade of gasoline is very important to help prevent engine damage and loss of
engine performance.

The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler
flap. This rating may be specified according to AKI (CLC) or RON (ROZ) standards.

If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using
TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more
information on 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 (methyl 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 alcohol):

  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 condition.

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 criteria 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 performance problems.

Damage to the engine and fuel system and performance problems caused by using fuels

that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission 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

Please first read and note the introductory information and heed the WARNINGS

Additives are used to improve the quality of the gasoline.

Fuel quality impacts the operating performance, efficiency and service life of the engine. Therefore,
use high quality gasoline that is already blended by the fuel supplier with suitable gasoline additives
that do not contain metal. The additives provide corrosion protection, clean the fuel system, and help
prevent deposits on the engine.

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.

Using incorrect gasoline additives can cause extensive engine damage as well as damage

to the catalytic converter.

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.

Working in the engine compartment

Introduction

In this section you’ll find information about:

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.

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.

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.

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.

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.

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.

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.

Always let the engine cool down completely before carefully opening the hood.
Hot parts of the engine and the exhaust system will burn skin on contact.

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) (automatic) or
Neutral (manual only).

– 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

⇒ Starter button.

– Always keep children and others away from the engine compartment and never leave
them unsupervised.

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.

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!

Never short-circuit the electrical system. Be especially careful when using jumper cables.

The vehicle's battery could explode!

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.

Read and heed the important information and warnings on cleaning the engine

compartment

⇒ Cleaning the engine compartment.

WARNING

Moving parts in the engine compartment can cause serious personal injury on contact.

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.

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.

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!

  Never smoke near the engine compartment.
  Never work next to open flames or sparks.
  Never pour or spill operating fluids or other flammable liquids 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 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.

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.

Engine oil specifications

Please first read and note the introductory information and heed the WARNINGS

The engine oil used must conform to exact specifications.

Using the proper engine oil is important for the functionality and service life of the engine. Your engine
was factory-filled with a high-quality multi-grade oil which can usually be used throughout the entire
year.

Engine oils are constantly being improved. Authorized Volkswagen dealers and authorized
Volkswagen Service Facilities are always up-to-date regarding new developments and changes.
Volkswagen therefore recommends that you have the engine oil changed by an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility.

Engine oil quality is based not only on requirements for engines and exhaust treatment systems, but
also on fuel quality. Engine oil comes into contact with fuel and fuel residue in all internal combustion
engines, causing engine oil to age and its lubricating qualities to deteriorate.

Your engine was factory-filled with a high-quality, “synthetic” all-season engine oil that meets strict
Volkswagen oil quality standards and has a viscosity grade of SAE 5W-40. or SAE 5W-30. You can
use this oil for normal driving in all temperatures.

If you need to add oil between oil changes, use only a high quality oil that expressly complies with the
Volkswagen oil quality standard specified for your vehicle's engine:

Engines

Engine oil specification

Gasoline engines

VW 502 00
VW 503 00
VW 504 00

At the time this Manual was printed, the engine oils available in the U.S. that meet these Volkswagen
standards are “synthetic” oils. This does not mean, however, that any “synthetic” engine oil will meet
Volkswagen standards. Always use an approved oil that expressly complies with the Volkswagen oil
quality standard that applies to your vehicle's engine.

General recommendations:

If “synthetic” oil that meets the applicable Volkswagen oil quality standard with viscosity grade
SAE 5W-40 or SAE 5W-30 is not available in your area, be sure to use a viscosity grade suitable for
the climate, season, and operating conditions that exist where the vehicle is used. Make sure the oil

meets the quality standard listed in

⇒ table on page 287.

NOTICE

If you need to add oil and there is none available that meets the Volkswagen oil quality

standard your engine requires, you may add a total of no more than 1/2 quart (0.5 liter) of a
high-quality “synthetic” oil that meets ACEA A3 specifications and has a viscosity grade of
SAE 5W-40 or SAE 5W-30.

Use only a high quality engine oil that expressly complies with the Volkswagen oil quality

standard specified for your vehicle's engine. Using any other oil can cause serious engine
damage that will not be covered by any Volkswagen Limited Warranty.

Do not mix any lubricants or other additives into the engine oil. Doing so can cause engine

damage! Damage caused by these kinds of additives are not covered by any Volkswagen
Limited Warranty.
