STARTING
PROCEDURES
WARNING
•
Fasten safety belts before driving.

•
Never
start or let the engine run in a
confined or enclosed, unventilated

area.
Exhaust fumes from the engine
contain carbon monoxide, which is a

colorless
and odorless gas. Carbon monoxide can be
fatal
if inhaled.

•
Never
leave engine idling unatten­

ded.
An unattended vehicle with a run­
ning
engine is potentially hazardous.

•
Do not park or operate the vehicle in

areas
where the hot exhaust system may come in contact with dry grass,

brush,
fuel
spill
or other
material,

which can cause a fire.

•
Do not leave engine unattended at

idle.
When starting engine, be ready to
drive off immediately. Maintain moder­
ate
speed until the engine is
com­

pletely warm. Remember that
your
en­
gine performs best at operating
tem­
perature.
Automatic
Transmission
Engine will only start with selector lever in
Neutral or Park.

Manual
Transmission
Start with gearshift lever in Neutral, clutch

pedal
depressed, so that the starter only

has
to crank the engine.

Starting
engine
•
Do not depress accelerator pedal
when starting. At extrem low temperatures
the engine will probably start better, if you depress accelerator pedal slighly.

•
As soon as the engine starts, release
the ignition key.

•
If the engine does not start the first time
or
stalls,
turn
the ignition off and restart. Depress the accelerator pedal slowly
during the second starting attempt.

•
Operate the starter for no more than

10
seconds.
•
Allow about 30 seconds between each

starting
attempt.
STOPPING
ENGINE

Do not stop engine immediately after
hard or extended driving. Keep engine
running for about two minutes to pre­

vent
excessive heat build-up.
WARNING
•
Before you check anything in the
engine compartment, stop the engine and let it cool down. Hot components

can
burn skin on contact.

•
The radiator fan switches on auto­

matically
when the coolant reaches a cer­

tain
temperature and will continue to run
(even
with ignition off) until the coolant
temperature drops.

engine rpm (revolutions per minute) for all gears after the break-in period. Before
'eaching this area, the next higher gear
snould be selected or the foot eased off
the accelerator pedal. Earlier shifting saves fuel and reduces noise.
Sniff to the next lower gear when the en-

4 - Coolant temperature
gauge X
tare applicable The needle in the coolant temperature
gauge will indicate the temperature of the
coolant shortly after the ignition is
switched on.
When ignition is switched on the warning light (c) will flash for a few seconds as a
functional check.
a - Engine cold
Avoid high engine speeds and heavy throt­ tle when the needle is still in this area of
the
dial.

b - Normal temperature During normal running the needle will re­
main somewhere in the middle of the
dial.
If the engine is working hard at hign a--
bient temperatures, the needle may as:
go further to the right, but this is no cause
for concern so long as the coolant
tem­
perature warning light does not start

flashing.

c - Warning light If the light flashes when driving first check
the coolant temperature gauge. If the nee­
dle is in the normal range, add coolant at the next opportunity. If the needle is in the warn­
ing range, either the coolant level is too low
or the coolant temperature is too high. Move the vehicle a safe distance off the

road,
stop the engine and depress the
emergency flasher switch.
The fan should be operating when the warning light is on (listen for fan, located in
front of car behind grille).
WARNING • To reduce the risk of being burned,
never open the hood if you see or hear
steam or coolant escaping from the
engine compartment. Wait until no
steam or coolant can be seen or heard
before carefully opening the hood.

AUXILIARY HEATER* (Syncro models only)
The auxiliary heater* heats the coolant in the heating circuit and supplies the heat exchanger in the normal heating system
and the additional heat exchanger* for the
passenger compartment heating with heated coolant.
The system is switched off and on or the
switch-
on time preselected by means of a
switch and indicator unit located on the left under the instrument panel.
Air distribution and regulation is done with the controls of the normal heating and
ven­

tilation system (see "Ventilation/Heating"
on page 51).
The auxiliary heater can be used with vehicle stationary or when it is moving.
When vehicle is stationary, the heater only runs for a maximum of 30 minutes in order
to avoid draining the battery. It also switches off automatically when a coolant
temperature of 80° C (175° F) is reached.
When the coolant temperature drops below 70° C (158° F) the heater is auto­matically switched on again. The heater runs on fuel from the vehicle
tank and uses up to half a litre (one quart) per hour. Controls

Gc not tow a trailer during the break-in kriod of your vehicle.
Keep an eye on your coolant tempera-
fere gauge. If coolant temperature warn- rc light comes on pull off the road to a sa's place to allow engine to cool down.
Maximum trailer weight
A vailer for your vehicle is limited to a
typi-

ca class I trailer. The maximum gross
Bier weight and the tongue load must not
eoeed the specifications listed in the
[fechnical Information/Data section of this
ranual.

Do not exceed the gross vehicle weight
•rhich is the weight of the driver, passen­ ger, luggage, trailer hitch and tongue
weight of the loaded trailer. Trailer hitch
Use a weight-carrying hitch conforming to
the gross trailer weight. The hitch must be suitable for your vehicle and trailer and
securely bolted to the body. Always check
with the trailer hitch manufacturer to make
sure that you are using the correct hitch. Do not use a bumper hitch.
The hitch must be installed in a way not to interfere with the impact-absorbing
bumper system. No modifications should
be made to the vehicle exhaust and brake
systems. From time to time check that all hitch mounting bolts remain securely fas­

tened.

If not towing a trailer for a long period of

time,
remove the trailer hitch. This pre­
vents the hitch from causing damage should your vehicle be struck from behind.
When removing the trailer hitch, seal all bolt holes to prevent water and exhaust
fumes from entering the vehicle.
Trailer brakes If your trailer is equipped with a braking

system,
check to be sure that it conforms
to all regulations.
The trailer brake system must not be di­ rectly connected to the vehicle's brake sys­

tem.
Tire pressure
When towing a trailer, inflate the tires of
your vehicle to the cold tire pressure listed on the label on the left front door jamb. In­
flate trailer tires to trailer and tire manufac­
turer's specifications.
Safety chains
Always use safety chains between your car and trailer.
Trailer lights
Trailer lights must meet all regulations. Do not connect the trailer light system directly
to the light system of your vehicle. Be sure
to check with your Volkswagen dealer for
correct wiring, switches and relays.
Before you tow a trailer
Correct and even load distribution. All ob­
jects inside the trailer should be held securely in place to guard against shifting, be it forward, backward or sideways.
Never allow a passenger in a moving
trailer.

CARE

COOLING
SYSTEM
The cooling system
is
sealed and gener­ ally requires little attention.
The cooling system has been filled at the factory with
a
permanent coolant which
does not need to be changed. The coolant

consists
of a
mixture
of
water
and the
manufacturer's coolant additive
G 11 —

antifreeze
on
glycol basis with anticorro-
sion additives (40% for USA
models;
50%
for Canadian models).
This
mixture
assures
the
necessary frost protection
and protects
the
entire cooling system
against corrosion and
scaling,
and raises
the boiling point of the coolant.
Do
not
reduce
the
concentration
of the

coolant
in the
summer
by
adding plain
water.
The coolant additive proportion
must
be at least
40%
but not more than

60%,
to
maintain the antifreeze protection
and the cooling efficiency. For year round driving, antifreeze is added
at the factory for temperatures down to:

-13°
F/-25°C(USA)

-40°
F/-40°
C
(Canada)

Only
use
quality phosphate-free
anti­

freeze containing ethylene glycol. Such antifreeze
is
available at
your
Volkswagen

dealer.

WARNING Antifreeze is poisonous. Always store antifreeze in its original container and

well
out of the reach of children. If you drain
the
coolant,
it must
be
caught
and

safely stored. Drained coolant should normally not be reused. Always des-

pose
of used coolant observing all en­
vironmental regulations.
Coolant losses
Coolant losses may indicate
a
leak in
the

cooling
system.
In
this
case,
the
cooling
system should
be
inspected immediately by
your
Volkswagen dealer.
It is not
suffi­

cient merely to add coolant.

In a
sealed system, losses can only occur
if
the
boiling point
of the
coolant
is ex­

ceeded as
a
result of overheating.
Overheating can occur
if:

•
the
flow
of air to the
radiator
is

obstructed
by
leaves, dust, insects
or by

additional
lights installed
in
front
of the
radiator grille;

•
the boiling point of the coolant has been
reduced
due to an
incorrect mixture
of

coolant and water;

•
the
radiator fan
is not
working
- see

"Radiator
fan",
or;

•
the vehicle is being driven up
a
long
hill
j

in
a
low gear with engine speed
very
high
and
at
very
high ambient temperature
-

see
"Radiator fan".

If
the cause for the overheating cannot
be

determined
and
corrected, contact
your

Volkswagen dealer immediately, other-
I
wise serious engine damage could result.

Checking
the coolant level

The coolant level should
be
checked from time
to
time, and always before going on
a
longer
trip.

WARNING

To
reduce the risk of being burned, never open the hood if you see or hear
steam or coolant
escaping
from the en­
gine compartment.
Wait
until
no steam

or
coolant can be seen or heard before
carefully opening the
hood.
Expansion
tank
The refill tank and
the
expansion tank are in
the
engine compartment.
The coolant level
is
normally checked only in
the
refill tank (behind
the
license plate
lid).
The expansion tank needs checking only
if
a
large amount
of
coolant
is
lost
or if the

warning
light
in the
water temperature gauge lights up.
On
the
refill
and the
expansion tank,
the

cap
need
not
be taken
off,
since the tanks
are transparent.

On
the refill tank, the coolant level must
be

between
the
min.
and
max. marks when
engine
is
cold
and not
running. When
engine
is
warm, coolant level
may be

slightly above max. mark.
The expansion tank
is
equipped
with
an
electric coolant level checking device.
When the coolant level is too low, the warn­ ing
light
in the
coolant temperature gauge

(see
page
43)
will flash
until
the
coolant
level has been restored
to
normal.

Always heed WARNINGS on page 97.
