VEHICLE CARE
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.

VEHICLE
CARE

AIR CLEANER
A
dirty
filter
element reduces engine
out­
put and increases fuel consumption and

can
cause premature engine wear.
Normally, it is not required to service the
air cleaner more often than recommended in the Maintenance booklet. If the vehicle

is
driven on very dusty roads, the air

cleaner
must be serviced more frequently,

even
daily. We recommend
that
you have
the air cleaner serviced by your
Volks­

wagen dealer or a qualified workshop.
If
your
air
filter
must
be
changed more
frequently,
we
recommend
that
you have
your
Volkswagen dealer show
you the
procedure
before
you
attempt
doing
it

yourself.

The
paper
filter
element must never
be
cleaned
or
soaked
with
gasoline, clean­

ing
solvents or oil. POWER STEERING*
The
fluid
reservoir is located behind the
licence
plate lid.

The
power steering is filled
with
ATF Dexron®.

A
correct
fluid
level in the reservoir is im­
portant
for the proper functioning of
power steering.
With the engine running, the
fluid
level in the power steering system must be
checked
at regular intervals. The
fluid
level
should always be between the "max"
and "min" markings. If the level should go below the "min" marking, have the power
steering system inspected by your
Volks­

wagen dealer. It is not sufficient to
just
add hydraulic fluid.
WARNING

•
Be
sure
not to
confuse brake fluid

and
hydraulic fluid.
If
the wrong fluid
is
used,
the systems may fail.

•
If the
power steering system should

fail,
or if the
engine
is not
running
(for

example
while
being
towed),
you
will
still
be
able
to
steer
the
vehicle, how­
ever, more
effort
will
be required.
Note

Since
the hydraulic
fluid
also functions as

a
lubricant, serious damage to the pump
and to other components of the system
could result if there is insufficient hydraulic

fluid
in the system.

Always
heed WARNINGS on page
97. "where applicable
