pos­

sible.

•
Do not allow battery acid to contact

eyes
or
skin.
Flush any contacted area

with
water
immediately.

•
Improper use of booster battery to

cause
an
explosion.

•
Vehicles batteries generate explo­

sive
gases.
Keep sparks, flame and lighted cigarettes away from batteries.

•
Do not charge a frozen battery; allow
it to thaw out first. Gas trapped
in the ice may cause an explosion.

•
Do not try to jump start any vehicle

with
a low electrolyte level in the bat­ tery.

•
The voltage of the booster battery
must also have a 12-volt rating. The

capacity
(Ah) of the booster battery

should
not be lower than
that
of the
dis­

charged
battery. Use of batteries of dif­
ferent voltage or substantially different

Ah
rating may cause an explosion and
personal
injury.
•
Applying
a
higher
voltage
booster

battery
will
cause
expensive
damage
tc

sensitive
electronic
components,
such
as
relays,
radio,
etc...

•
Vehicle

LIFTING
VEHICLE

The vehicle should
never
be lifted or
jacked
up from underneath the engine
oil
pan, the transmission housing, or the

front
or rear axle.
This
could lead to serious damage.
The same lifting points as illustrated for the hoist also apply when using a floor jack. To
avoid damage to the underbody or chassis

frame,
it is necessary to insert a rubber pad between the floor jack and the lift

points.

Lifting
with workshop hoist
and with floor jack

Make
sure there is sufficient clearance
between pads and vehicle before driving
vehicle on to hoist.
WARNING
When removing components such as engine block, transmission housing,

fuel
tank, wheels,
front
or rear axle, anchor vehicle to hoist or add corre­
sponding weights to maintain the cen­
ter of
gravity.
Otherwise the vehicle
might tilt or slip off the hoist, causing
serious damage or personal
injury.
•
To reduce the risk of serious perso­

nal
injury
and vehicle damage, lift
vehicle only at the special workshop hoist and floor jack lift points illustra­

ted.
Failure to lift vehicle at these points could cause the vehicle to tilt or
fall

from a lift when, for example,
heavy
components such as the engine block
or transmission are removed result­
ing
in a change in vehicle weight and

balance.

•
If you must lift
your
vehicle with a
floor jack to work underneath, be sure
the vehicle is safely supported on
stands
intended for this purpose.
Lifting
points

Front

At the
front
jacking point.
Rear

At rear cross member.
The vehicle must be lifted only at the lift
points illustrated.

Lifting
with vehicle jack Refer to the "Changing a wheel" on page

TECHNICAL
DESCRIPTION

EMISSION
CONTROL SYSTEM
In the
interest
of
clean
air Pollution of our environment has become

a
problem
that
is of increasing concern to
all of us. We urge you to
join
us in our ef­

forts
for cleaner air in controlling the pollu­
tants emitted from the automobile.

You
can make a significant contribution to
keeping our air clean by:
• Always using lead free gasoline.
• Not
letting
your vehicle idle
unnecessa­

rily.
• Following the recommended preven­
tive maintenance schedule contained in
the maintenance booklet.
• Not removing or altering the emission
control system.
• Taking the precautions described
below to prevent damage to the emission
control system in your vehicle.

Volkswagen
warrants the Emission
Con­
trol
System in your new vehicle under the
terms and conditions set
forth
in the War­ ranty booklet.

Your
Volkswagen is equipped
with
such a
system,
which contains the following major components.
Catalytic
converter

The catalytic converter is an efficient
"clean-up"
device
built
into
the exhaust system of the vehicle. The catalytic conver­
ter burns the undesirable pollutants in the exhaust gas before it is released
into
the
atmosphere.
The
exclusive
use of
unleaded
fuel
is cri­
tically
important
for the
life
of the
cataly­

tic
converter
and
proper
functioning
of
the
engine.

The
catalytic
converter
will
be
perma­
nently
damaged
by
•
exceeding
the "max"
marking
when

adding
engine
oil (see
page
99)
• push or tow
starting
your
vehicle

•
misfiring
of the
engine

•
turning
off the
ignition
while
the

vehicle
is
moving
or
•
other
unusual
operating
conditions. Do not
continue
to
operate
your
vehicle

under
these
conditions, as
otherwise

fuel
can
reach
the
catalytic
converter.

This could
result
in
overheating
of the
converter,
requiring
its
replacement.

For
maintenance intervals refer to your
Maintenance booklet.

Oxygen
Sensor (OXS)
The oxygen sensor, installed in the exhaust manifold, continuously
senses

the oxygen content of the exhaust and

signals
the information to an electronic
control
unit.

Carbon
canister

The vehicle is equipped
with
a carbon canister to prevent fuel vapor from
esca­
ping
into
the atmosphere.
The vapor is passed
into
the carbon canister, where it is retained when the
engine is turned off. When the engine is running, a valve allows air
into
the canister,
and the fuel vapor is passed to the engine
for combustion.
The system does not require any main­
tenance.

Notes

Spark
plugs are replaced during the Volks­
wagen scheduled Maintenance service. If
you replace the spark plugs between the

Volkswagen
Maintenance services, the
following should be noted: • Engine, spark plugs and the ignition
system are matched. To avoid faulty opera­

tion
or engine damage, use only Original

Volkswagen
spark plugs. It is especially important to note the number of electrodes
and heat value. • Since spark plug specifications may

change
for technical reasons during a cur­
rent
model year, we recommend
that
you
obtain your spark plugs from a Volks­
wagen dealer who has the latest informa­
tion.

TECHNICAL DATA

WEIGHTS

The vehicle capacity weight (max. load), the
Gross
Vehicle Weight Rating
(GVWR),

and
the
Gross
Axle Weight Ratings
(GAWR)
for
front
and rear, are listed on the

Safety
Compliance Sticker on the
left
door-
jamb.
The gross vehicle weight rating includes the weight
of the
basic
vehicle plus
full

fuel tank,
oil and
coolant, plus max. load which combines passenger (150 pounds/
68 kg per designated seating position) and luggage weight. Luggage weight
is not

increased
by the use of a
roof rack,

unless
passenger capacity
is
reduced
accordingly.
The gross axle weight rating
is the
maxi­ mum load
that
can be applied
at
each axle
of the vehicle.

Syncro

When driving off-road,
the
Gross
Vehicle
Weight
(GVWR)
must
be
reduced
by 440
lbs (200 kg).
WARNING

•
The actual
gross
axle
weight
rating
at the
front
and rear axles should not
exceed the permissible weights, and

their
combination must not exceed the
Gross
Vehicle Weight Rating.

•
Exceeding permissible
weight

ratings can result in vehicle damage,
accidents and personal injury.
Note

The vehicle capacity weight figures apply when
the
load
is
distributed evenly
in the

vehicle (passengers
and
luggage). When
transporting
a
heavy load
in the
luggage
compartment,
the
load should be carried
as
near
to
the rear axle as possible so
that
the

vehicle's
handling
is not
impaired.
On no
account should
you
exceed
the
maximum
permissible axle loads
or the
maximum

gross
vehicle weight. Always remember
that

the vehicle's handing
will
be
affected by
the
extra
load,
and
adjust your speed accord­ingly.
Roof
weights

The maximum permissible roof weight
on
the station wagon
and
kombi
is 220 lb,
100
kg. The
roof luggage rack
on the

campmobile
with
pop-up roof allows only 110 lb/50 kg.

For
more details see page 68.

Maximum permissible
trailer

weights

Braked
trailer 900 kg (2,000 lb.) Unbraked trailer 600 kg (1,3201b.)
Tongue load 75 kg
(
1651b.)

Do not exceed the
weight
limitations of
your
trailer
hitch.
