VEHICLE OPERATION
After driving over
difficult
terrain,
espe­
cially through water or mud, the following
is
important:
• Disengage the differential lock*.
• After long drives through deep mud, the
brakes must be checked and cleaned if
they are
dirty.
This will prevent damage to
the brakes and premature wear.
• After driving through deep water, take
out oil dipstick and check to see whether
there are drops of water on the dipstick or if the oil level has risen. In
that
case,
the oil
must be changed immediately.
• If during an off-road drive the vehicle

has
become stuck (dug its way
into
the
ground) or the underside was stuck by
rocks
or similar, check undercarriage,
brake lines and oil pan for damage. • The engine compartment and vehicle
underbody must be cleaned if they are
very
dirty
so
that
the function of all mova­ ble and electrical/electronic parts is main­
tained.
•
Clean
heavy soil from wheels and tires,

check
tires for damage or foreign objects in treads.
•
Clean
turn
signals, lights and license
plate.
• Dry brake system by driving a short dis­
tance
with
brake pedal slightly depressed.

This
will help regaining normal braking ac­
tion
and help prevent the possibility of the
vehicle pulling to one side while braking.
Performance
testing

If the
Vanagon/Transporter
Syncro re­

quires
testing
on a
dynamometer
(en­

gine
output
analysis and
brake
test)
the

transaxle
drive
shaft
must
be discon­ nected.
The
differential
lock
must
not be en­ gaged.

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
your vehicle
with
ordinary tools, should the
need
arise and trained personnel be un­

available.

VEHICLE CARE
ENGINE OIL
Engine oil consumption t 3 normal for your engine to consume oil.

T-Q
rate of oil consumption depends on
re quality and viscosity of
oil,
the speed at
Mich
the engine is operated, the climate,

read
conditions as well as the amount of : ution and oxidation of the lubricant.

Because
of these variables, no standard
•e:e
of oil consumption can be esta-
:
shed,
but drivers should expect an in­
creased
oil consumption at high speeds
s.nd when the engine is new.
• The
engine
in your
vehicle
depends
on oil to
lubricate
and cool all of its
mov­

ing
parts.
Therefore
the
engine
oil
should be checked
regularly
and
kept
at
the
required
level.
•
Make
it a
habit
to
have
the
engine
oil

level
checked
with
every
fuel
filling.

• Lack of
sufficient
engine
oil may
lead

to
severe
engine
damage.

• The oil pressure
warning
light
is not
an oil
level
indicator.

Always
heed
WARNINGS
on
page
97.
The
engine oil dipstick and the oil filler

neck
are located behind the license plate

lid.

Checking the
engine
oil
level

The
best time to check the engine oil level
is
when the oil is warm.
• Turn off the engine.
• To get a true reading, the vehicle should

be
on level ground. After turning off the en­

gine,
wait a few minutes for the oil to return
to the crankcase.
• Flip license plate down.
• Pull out dipstick and wipe it clean
with
a

rag.

• Reinsert dipstick; push it in all the way. • Pull dipstick out again. The oil level is
correct if it is between the "max" and "min" marks on the dipstick.
• If oil level is below "min" mark, or not
showing on dipstick, add oil immediately.
• Make sure
that
the dipstick is com­
pletely in.
Adding
engine
oil • Unscrew cap from oil filler neck.
• Pull extension tube out of filler neck as
far as it will go.
• Only add the amount of oil needed. The
difference between the "min" and "max" marks on the dipstick is about
1
U.S. quart
or
1
liter. Always select a quality oil
with
the
correct specification. See "Lubricants" on
page
85.
Do not exceed the MAX
marking.

Otherwise,
the excess oil may be drawn in
through the crankcase breather into the exhaust system. The oil would then burn in
the catalytic converter and cause dam­
age.

•
Push
in the extension tube, replace fil­
ler cap and hand tighten securely.

WARNING

The oil
filler
cap
must
be secure to avoid oil spill causing
fire
hazard.

VEHICLE CARE
Changing the
engine
oil
Have
your engine oil changed regularly,
but at least twice a year (see Maintenance
booklet).

This
is very important because the lubri­ cating properties of oil diminish gradually
during normal operation of the vehicle.
If you drive mostly short distances, or if
you operate the vehicle in dusty
areas,
or under predominantly stop-and-go traffic
conditions, or when temperatures remain below freezing for extended periods, the
engine oil should be changed more fre­
quently.

Due
to the detergent additives in the oil,
the fresh oil will look dark after the engine
has
been running for a short time. This is
normal and there is no reason to change
the oil more often than recommended by
the manufacturer.

Always
heed
WARNINGS

WARNING

•
Drain
the oil
into
a
container
that
is
designed for
this
purpose, one
that
is
large
enough to hold at
least
the oil

filling
of your
engine.

•

• Engine oil is poisonous. Keep it
well

out of the
reach
of children. Con­

tinuous
contact
with
used
engine
oil is
harmful
to your skin.
Always
protect

your skin by

oil by
taking
it to
a used
engine
oil collection
facility
in
your
area,
or
contact
a service
station.
• Turn off the engine.
• Remove the oil drain plug (arrow) when
the engine is still warm and allow the oil to
drain.

•
Always
use a new
gasket
when

reinstalling
the plug. Do not
overtighten.

•
Fill
the engine
with
oil. Do not
overfill.

Always
check engine oil level
with
dipstick
as
described on previous page.

Engine
oil capacity is listed under

"Capacities",

AUTOMATIC TRANSMISSION FLUID / MANUAL TRANSMISSION OIL
Automatic Transmission Fluid
The torque converter and the transmis­
sion are lubricated with Automatic Trans­ mission Fluid (ATF).
The final drive requires hypoid oil SAE 90,
which does not have to be changed.
Checking the ATF level
The ATF has to be checked at frequent intervals, for instance, when the engine
oil is being checked or at least at the intervals specified in your Maintenance
booklet.
Always heed WARNINGS on page 97. A correct ATF level is very important for
transmission operation.
To obtain an accurate reading, the
vehicle must be on level ground, and the
fluid must have reached operating
tem­

perature. Normally, after a cold-start the
fluid will reach operating temperature when the vehicle has been driven for ab­
out 6 miles or 10 km. If the ATF is too cool
or too hot, the fluid level reading will be inaccurate.
WARNING Before checking the ATF, the selector
lever must be securely locked in the Park position and the parking brake ap­
plied firmly.
Checking the ATF level is potentially hazardous because the hot engine has
to be running during the check. Do not
attempt to check the ATF before read­ ing all WARNINGS on page 97.
The ATF filler neck is in the engine com- partement on the left hand side. The dip­
stick is attached to the
plug.
Pull it out
and wipe clean first before inserting it to
take a reading. The Automatic transmission may be da­
maged by even a tiny speck of dirt.
Only use lint free rags to wipe the dip­
stick.
To get a true reading, the ATF must be at operating temperature.
You have enough ATF if the fluid level is between the two marks on the dipstick. I:
should never be above or below these marks. If level is too high or too low do not
just add or drain ATF. Have your dealer check and correct the cause as soon as possible.
For correct ATF specifications, see "Lub­
ricants" on page 85.
Changing the ATF
The ATF has to be changed at the inter­ vals specified in your Maintenance boo­klet.
Do not tow the vehicle or run the engine
without ATF in the transmission.
Manual Transmisson Oil Both transmission and final drive are
combined in one housing. The lubrican: used is hypoid oil which does not have tc
be checked or changed. If you shoulc
suspect a leak, contact your VW dealer.

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.
