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

Tire
care
Inspect your tires at least every 2,000
miles (3,000 km) for wear and damage.

WARNING
• Avoid
damaging
tires
and
wheel

rims.
If you
must
drive
over
a
curb
or

other
obstacle,
drive
slowly
and at an
angle.
Frequently
check
tires
for un­

even
wear
and
damage.

•
Remove
imbedded
material.

•
Replace
worn
or
damaged
tires

immediately.

•
Replace
missing
valve
dust
caps.
• Keep oil,
fuel,
brake
fluid,
etc.
away

from
tires.

• Keep
tires
inflated
correctly.

• Mark tires before removing them.
Remount tires on the same vehicle side

because
the rotation direction should stay
the same.
• Store removed tires in a
cool,
dry and
preferably dark place. Tires which are not
on wheels should be stored standing up.

Tires
age even if they are not being
used.

Tires
which are older than 6 years should only be used cautiously in an emergency.
Wheels
and
tire
replacement

Wheels
and tires approved by the manu­
facturer have been specially matched to
your vehicle and contribute largely to the road-holding and driving characteristics of
the vehicle.
• Fitting and repairing tires requires
expert knowledge and special tools. This
work should only be performed by a
spe­
cialist.
• For safety reasons, tires should be

replaced
in pairs and not individually. The
tires
with
the deepest tread should always be mounted on the
front
wheels.
• In the interest of maximum safety and
best all-around vehicle handling, always
buy replacement radial tires
that
have the

same
specifications
with
regard to
tire

size,
design, load carrying capacity, tread pattern, tread depth etc. This also applies
to Volkswagen recommended alternate replacement tires.
• Never mount used tires if you are not
sure of their previous history.
• Whenever replacing a tubeless tire,
always install a new valve stem. Tire repair
should only be performed by a specialist.
WARNING

•
Never
mix
tires
of
different
design
such as
steel
belted
radials
with
radial
bias
belted
or
bias
ply
tires
etc.
Mixing

tire
types
will
adversely
affect
road
holding
and can
lead
to loss of
vehicle

control
and
personal
injury.

• New
tires
do not possess
maximum

traction.
They
tend
to be
slippery.
Break
new
tires
in by
driving
cautiously

at
moderate
speed for the
first
100

miles
(160
kilometers).

Applies
additionally
to the Syncro:

All
four wheels on the vehicle must always have tires of the same
size,
construction
and tread type so
that
the viscous coupling

does
not abnormally activate the
front

wheel drive. Different tires on the
front
or rear wheels exert additional stress on the
drive
train
components, causing increa­

sed
tire
wear and impair vehicle control.
