2013 VOLKSWAGEN JETTA Fuel

Winter diesel
At temperatures below 20 °F (-7 °C), wax separation in ULSD occurs. Wax may clog the fuel filter or
tank filter and keep the engine from running.
To help prevent the filter from being clogged with wax, the fuel filter in your vehicle is heated with
warm fuel when the engine is running (filter preheating system). Heating the fuel filter makes it
possible to use your vehicle with ULSD down to about -10 °F (-24 °C).
If you expect temperatures below +5 °F (-15 °C) ask your fuel dealer if their ULSD is sufficiently
winterized.
If non-winterized or insufficiently winterized diesel fuel has already thickened to the point that the
engine will not start, move the vehicle to a heated garage or workshop until it has warmed up.
Cold diesel engines normally produce louder noises during winter conditions than during warmer
periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The
exhaust gas volume varies depending on the outside temperature.
Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the
warm-up period.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.

NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x The vehicle is designed to run on diesel fuel containing methyl ester biodiesel in
concentrations of 5% or less. Never use methyl ester biodiesel in blend levels higher than 5%
(5%/ methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester biodiesel blends in levels greater than 5% may cause serious damage to the fuel injection
system and to the engine. This could lead to expensive repairs that will not be covered by any
Volkswagen Limited Warranty.
x 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.

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.
Getting ready to work in the engine compartment

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
Diesel engines with diesel particulate
filter
VW 507 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 .
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.
NOTICE
x 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.
x 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.

WARNING
Improper care and cleaning of vehicle components can impact the safety features of the
vehicle and cause severe injuries.
x Always clean and maintain vehicle components according to manufacturer's instructions.
x Only use approved or recommended cleaners.

NOTICE
Vehicle care products containing solvents can damage plastics and other vehicle the materials.
Wash the vehicle only at specifically designated wash locations to help prevent water
contaminated with oil, grease and fuel from entering the storm drain sewer system. In some areas it is
against the law to wash motor vehicles anywhere than other than at specified designated car washing
locations.
When buying vehicle care products, try to choose those that are not harmful to the environment.
Never throw out vehicle care products with ordinary household waste. Always read and heed all
the instructions and all WARNINGS on the package.

Unidirectional tires
Unidirectional tires are designed to rotate only in one direction. Unidirectional tires have arrows on the
sidewalls that show the direction of rotation . Unidirectional tires must always be mounted according to
the specified direction of rotation in order to deliver their best grip, braking performance, low road
noise, and good wear as well as good hydroplaning resistance.
If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully,
since the tire is no longer being used as designed. This is particularly important on wet roads. You
must replace or remount the tire as soon as possible in order to restore the correct direction of
rotation.
Rotating tires
To help ensure even wear on all tires, regular tire rotation according to the diagram ⇒fig. 139 is
recommended. In this way all tires can have about the same service life.
Volkswagen recommends that you have your tires rotated by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
Tires more than 6 years old
Tires age even if they are not being used. Physical and chemical processes reduce tire strength and
performance and cause them to harden and become brittle. Old tires can fail suddenly and without
warning.
Volkswagen recommends replacing tires that are 6 years and older. This also applies to tires that look
new (including the tire on the compact spare wheel) or that seem to still be usable with tread depth
that has not yet reached the legal minimum depth ⇒.
The age of each tire can be determined with the manufacturing date that is part of the U.S. DOT tire
identification number (TIN) .
Tire storage
Mark tires before removing them to help make sure that the previous location (left, right, front, rear)
and rolling direction can be maintained when remounting them. Store tires in a cool, dry and preferably
dark place. Do not store tires mounted on wheels standing up.
Tires not mounted on wheels should be covered to help protect them from dirt and stored vertically
(sitting on the tread).
WARNING
Aggressive fluids and materials can cause visible and invisible tire damage that can cause
tire blowouts.
x Always keep chemicals, oils, grease, fuels, braking fluids and other aggressive
substances away from tires.

WARNING
Tires age even if they are not being used and can fail suddenly, especially at high speeds,
causing loss of vehicle control, accidents, and severe personal injuries.
x Tires that are more than 6 years old can be used only in an emergency and even then only
with special care and at low speed.

Winter tires improve the handling characteristics of your vehicle significantly when driving under wintry
road conditions. Summer tires have less traction on snow and ice because of their design (width,
rubber composition, tread design). Volkswagen strongly recommends that you always have winter
tires or all-season tires installed on all 4 wheels on your vehicle, especially when winter road
conditions are expected. Winter tires also improve the vehicle's braking performance and help reduce
stopping distances during winter weather. Volkswagen recommends installing winter tires once
temperatures are below +45 °F (+7 °C).
Winter tires are no longer suitable for winter driving once the tread pattern is worn down to a depth of
3/16 in (4.8 mm). In addition, winter tire performance decreases with age – independent of the tread
profile depth.
When using winter tires:
x Obey state and country-specific legal requirements.
x Install winter tires on all 4 wheels.
x Use winter tires only under wintry road conditions.
x Only use winter tires with dimensions approved for the vehicle.
x Use only winter tires of the same tire belt design, the same dimensions (tread circumference), and
the same tread design.
x Follow speed restrictions according to the winter tire's speed rating code letter ⇒.
Speed restrictions
Winter tires are certified up to a top speed identified by speed rating code letters on the side wall .
In some vehicle models it is possible to set a speed warning in the menu in the instrument cluster
display
Top speed rating and tire inflation pressure for V winter tires depend on the engine installed in your
vehicle. Be sure to ask you authorized Volkswagen dealer or authorized Volkswagen Service Facility
about the maximum permissible speed and the required tire inflation pressure for the winter tires that
you plan to use.
WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were
designed can cause sudden tire failure including a blowout and sudden deflation, loss of
control, crashes and serious personal injuries.
x Winter tires have a maximum speed rating that may be lower than your vehicle's maximum
speed.
x Never drive faster than the maximum speed for which the winter tires installed on your
vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Never exceed the maximum load rating for the winter tires installed on your vehicle.
Install summer tires promptly in the spring. Summer tires offer better handling characteristics for
temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel
consumption.
The Tire Pressure Monitoring System must be recalibrated using the SET button whenever you
remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement

NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
As long as the indicator lights ÷, x or EPC are on, expect engine malfunctions, increased fuel
consumption, and loss of engine efficiency.
