fuel filter VOLKSWAGEN JETTA 2013 1B / 6.G Owners Manual

WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause unconsciousness and death.
x Never leave the vehicle unattended with the engine running. The vehicle could move suddenly or some other unexpected event could occur, resulting in property damage or personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away” vehicle condition.

WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Never apply additional undercoating or rust proofing on or near the exhaust manifold, exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.

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 or the diesel particulate filter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with
the fuel filler flap.

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.

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.

Obey all legal requirements regarding protecting a broken-down vehicle. For example, turning on the
emergency flashers and wearing a safety vest are mandatory in many countries.
