|he fuel filler neck is located above the -gnt
front
wheel. Syncro model: above the
-;nt rear wheel.
mm key A (see page 7) is used for the lock-
acle
tank cap. The syncro model has a separate key for the lockable tank cap.
capacity of the tank is 16.0 gal/60

:ers
(Reserve is 2.5 gal/10 liters of
total

rapacity).
5/ncro model: 18.5 gal/70 liters (Reserve

2
5 gal/10 liters of
total
capacity). Trouble-free refueling depends on the cor­
rect use of the filler nozzle.

Always
insert the nozzle fully
into
the fuel filler neck, to completely open the spring-loaded flap located
just
below the filler
neck opening. Make sure the filler nozzle

is
not tilted.

Do
not
fill
the fuel tank too quickly, other­
wise the fuel may foam up and cause the
nozzle
to switch off too
soon.

As
soon as the nozzle switches off auto­ matically for the
first
time, the tank is full.
Do
not try to add more fuel, because the

expansion
space in the fuel tank will be
filled - the fuel can then overflow when it
becomes
warm.
WARNING

Never
carry
additional
fuel
containers

in
your
vehicle.
Such
containers,
full
or

empty,
may
leak,
cause an explosion,
or
result
in

FUEL SUPPLY
Your vehicle is equipped with a catalytic converter and requires unleaded fuel.
For maximum engine performance, un­
leaded fuel with an octaine rating of 91
RON,
which corresponds to an anti-knock
index (AKI) of 87, is recommended.
Do not use leaded gasolines.
Deposits from leaded gasolines deacti­
vate the catalytic converter and thus
defeat its purpose to control exhaust emis­

sions.

Unleaded fuels may not be available
outside the continental USA and Cana­

da.
Therefore, we recommend you do not take your vehicle to areas or coun­
tries where unleaded fuel may not be
available. Octane rating
Octane rating indicates a gasoline's ability to
resist detonation. Therefore, buying the cor­
rect octane gas is important to prevent en­
gine "knock", which reduces performance and may cause engine damage.
Under high load operating conditions, un­
leaded premium gasoline may be used.
The 91 RON octane rating which you will find above the filler neck is based on the re­ search method. The AKI octane rating unsu-
ally displayed on USA gasoline pumps is
calculated as follows: Research octane number plus motor octane number, divided
by 2.
Regular fuels have an octane rating ranging
from 91 to 95 RON (Research Octane Number) or 87 to
91
AKI.
Do not use any fuel with octane ratings
lower than 91 RON or 87 AKI.
Gasolines containing alcohol
Gasoline containing alcohol is available at
gas stations in some areas. The gas pump may not be labeled to identify that alcohol
is present in the gasoline. If it is labeled, it
may not identify what amount and type(s)
of alcohol are used. We recommend you
use quality gasoline that is NOT blended
with alcohol. The use of fuel containing alcohol can cause loss of fuel econorr
and driveability and performance pre:

lems.
If these problems are experience:
we recommend you switch to anothe brand of gasoline.
Seasonally adjusted gasoline
Many gasolines are blended to perfor-
especially well for winter or summer drl
ing.
During seasonal change-over, wl
suggest that you fill up at busy gas statior I
where the seasonal adjustment is mo-r likely to be made in time.
Gasoline additives
A major concern among many aut: manufacturers is carbon deposit build-i:
caused by the type of gasoline you use.
Although gasolines differ from onr manufacturer to another, there is a cor-
mon thread. All gasolines contain props'
ties that can cause deposits to collect ad essential engine components, specificali
fuel injectors and intake valves. Althoug- most gasoline brands include additives tc
keep engine and fuel systems clean, the;,
are not equally effective.

Recent
fuel developments

Over
the past few years, more manufactu­ rers have been advertising detergent addi­
tives in their gasoline. These additives are primarily intended to keep fuel injectors

clean.

However,
they are not all equally effective
in reducing carbon deposit build-up on
intake valves. We are aware
that,
as of the

time
of printing, some manufacturers advertise and sell gasoline
that
contains
the proper deposit control additives
that

will

To
assure the long

performance of your car's engine, you should use gasoline brands
that
include these deposit control

additives.

If gasolines
with
additives are not
avail­

able,
contact your Volkswagen dealer
about proper fuel additives.

CORROSION
PROTECTION

The transmission,
front
and rear axle
assembly
surfaces have been treated at
the factory
with
a wax based coating for protection against corrosion. However, we
recommend to have the and the underside
inspected twice a year for any damage to
the protective coating preferably before and after the winter
season.
Have
neces­

sary
repairs done as soon as possible.
See
your dealer for correct procedures
and materials.

WARNING
Do not
apply
additional
undercoating

or
rustproofing
on or
near
the
exhaust
manifold,
exhaust
pipes,
catalytic

converter
or
heat
shields.
During
driv­
ing, the substance used for
under-

coating
could
overheat
and cause a

fire.

Engine
Compartment
When washing the engine compartment, only use commercially available grease
cutting solvents made especially for this
purpose.
Carefully follow directions
print­

ed
on the container by the manufacturer.
WARNING

Never
use gasoline,
Diesel
fuel
or sol­

vents
which
could
damage
rubber
parts
or
painted
surfaces and could
cause a
fire.

Chassis

The lower body shell of your Volkswagen
is
thoroughly protected against corrosion. However, it is recommended to have the
underside inspected twice a year. Any de­
tected damage to the undercoating, due to road hazards, should be repaired prompt­
ly. Oil based protective sprays must not be

applied.
Only tar or wax based anticorro-

sion
protectors are compatible
with
the
factory applied undercoating. Before ap­ plication, road
dirt,
salt spray deposits and
oily substances must be removed.

Whenever
the lower body
shell,
axle, transmission or engines assemblies have been repaired, the lost anti-corrosion
coating of the affected surfaces should be
reapplied.

Your
Volkswagen dealer has the appro­ priate materials, the necessary equipment
and is familiar
with
the application proce­
dure. Therefore, any additional corrosion protection work should be performed by a

Volkswagen
dealer.
Body
cavity sealing

All
body cavities which could be affecte: by corrosion have been given a thorouc"
protection at the factory.

This
sealing does not require any inspe:
tion
or additional treatments. If any wa should seep out of the cavity when tN
ambient temperature is high, it can M removed
with
a plastic scraper and -.
suitable solvent. Be sure to observe a
safety and environmental regulations.

VEHICLE CARE

Important
Consideration
for you and your car:

A
thorough and detailed preventive maintenance schedule has been de­

veloped
for your vehicle, which if followed

should
help assure you of years of reliable

and
dependable use. We strongly urge
you to give your dealer the opportunity to perform all scheduled maintenance and

necessary
repairs. He has the facilities,
original parts and trained specialists to
keep
your car running properly.

The
increasing use of electronics, sophisti­
cated
fuel injection and emission control

systems
together
with
the generally in­

creasing
technical complexity of today's automobiles has steadily reduced the

scope
of maintenance and repairs which

can
be carried out by vehicle owners.
Maintenance,
adjustments and repairs

usually
require special tools, testing de­

vices
and other equipment by specially
trained workshop personnel in order to as­
sure
proper performance, reliability and
safety of the vehicle and its many
sys­

tems.
Improper maintenance, adjust­ ments and repairs can impair the opera­
tion and reliability of your car and even
void your vehicle warranty. Above all oper­ ational safety can be adversely affected
creating unnecessary risks for vehicle oc­
cupants and others.
This
section describes a limited number of

procedures
which can be performed upon

Engine
Your engine was factory filled with an all- season high quality engine oil. If you need
to add oil between oil changes use any high quality petroleum or synthetic based
oil with correct specifications.
The following term must appear on the oil container singly or in combination with
other designations: "API Service SF or
SG".

Engine oils are graded according to their
viscosity. The proper grade to be used in your engine depends on existing climatic
or seasonal conditions. Refer to the temperature chart when
selecting engine oil. As temperature ranges of the different oil grades overlap,
brief variations in outside temperatures
are no cause for alarm. It is also permissi­ ble to mix oil of different viscosities if you
find it necessary to add oil.
When using SAE 10 W or SAE 5 W-20 or SAE 5 W-30 engine oil, avoid high speed
long distance driving if outside tempera­
ture rises above the indicated limits.
Engine Oil Identification Symbol
Select an oil for your vehicle which
con­

forms to the standards of the American Pe­
troleum Institute (API). A symbol has been added to the top of some oil containers to help in selecting the correct oil.
