Reduce the risk
of
scalding from
hot

coolant by following these steps.
• If the coolant reservoir cap must be
removed, wait until
the
engine
has

cooled down.
• Protect face, hands
and
arms
by

covering
the cap
with
a
large, thick
rag
to
protect against escaping fluid
and
steam.

• Carefully and slowly

to es­
cape before completely removing

cap.

•
To
help avoid being burned,
do not

spill
antifreeze
or
coolant
on the ex­

haust system
or hot
engine parts.
Under
some conditions, the ethylene
glycol
in
engine coolant
is
combusti­
ble.
If a
visual check shows that coolant level
and V-belt
are
normal,
but the
warning light continues to
flash,
contact
your
near­
est dealer
to

WARNING If the brake warning
light
does not go
out
with
the engine running and the parking brake released or lights up
while driving, the fluid level
in
the brake
fluid reservoir may
be
too low.
This might be
due
to
a
leak in one of the two independently functioning brake circuits.
If the brake pedal travel has increased,
one of the brake circuits may have

failed.
Avoid driving the vehicle and have it towed to the nearest Volkswa­
gen dealer or qualified workshop for re­ pair.
If brake pedal travel has not increased

and
braking performance remains un­

Malfunctions

if the
unit
does not
operate

• Outside temperatures may be below
41° For + 5°C.
• The air conditioner fuse may have blown. Turn the
unit
off and check fuse.

See
page 129 for use panel location.
General
hints

If
water
drips
under
the
vehicle

When outside temperature is high and the
air very humid, condensed water can drip
off the evaporator under the vehicle. This
is
normal and does not indicate a leak.

Payload
reduction

The weight of the air conditioner installed in your vehicle reduces the vehicle's load
carrying capacity. For weight information,

see
sticker on
left
doorjamb.

Maintenance
The condenser should be checked peri­
odically for cleanliness. If clogged
with

dirt
or insects, the condenser should be
washed down
with
water.
After the winter months and before ex­
tended summer
usage,
the air conditioner should be checked and, if necessary, ser­
viced by your Volkswagen dealer.

Notes

• Every time the heater is switched off,
the warm air and combustion air blowers continue running briefly to cool the heater
down quicker.
• To avoid draining the battery, do not
run the heater repeatedly when the engine

is
not running.
• When the heater is running on the
clockwork time switch, it must be switched
off by hand before attempting to start the
engine at low temperatures so
that
the

full
battery capacity is available to
turn
the
engine.

WARNING
Never
start
the
heater
or let the
engine

or the
heater
run in an enclosed, un-

ventilated
area.
Exhaust
fumes
from

the
engine
or the
heater
contain
carbon monoxide,
which
is colorless and
odorless. Carbon monoxide,
however
is a
very
harmful
gas, and may be
fatal

if inhaled.
Due to the
risk
of
fire
the
heater
must

not be used
when

VEHICLE OPERATION

OPERATE
YOUR VEHICLE ECONOMICALLY AND
MINIMIZE
POLLUTION
Your
personal
style
of
driving
determines your operating costs,
exhaust
emissions and noise levels. To obtain the best
possi­

ble fuel economy,
minimize
pollution
and

save
wear and tear on the engine, brakes
and tires, observe the following points:
• Keep a
light
foot
on the accelerator.
• Drive smoothly, avoid abrupt changes
in speed as much as possible.
• Avoid jack rabbit starts and sudden

stops.

• Avoid unnecessary idling. Turn the
engine off.
• "Warm up" idling wastes gas. Start the
engine
just
before you are ready to drive.

Accelerate
slowly and smoothly.
• Do not drive longer than necessary in
the lower gears. By upshifting early you
can
economize on fuel consumption. • Organize your trips to include in several
errands.
• Any additional weight carried in the
vehicle reduces fuel economy. Always keep cargo to a minimum and remove all

unnecessary
items.
• Remove roof and ski racks when not in

use.

• All electrical consumers contribute to

increased
fuel consumption. Therefore,

use
fan, rear window defogger, etc., only
when needed.
• Check your vehicle's fuel consumption
regularly. Keep a
written
tally sheet or use
the
trip
odometer. Fuel consumption will
vary
with
traffic, road and weather condi­
tions.
• Have your vehicle serviced by an

Volkswagen
dealer at the specified inter­
vals
(see page 95 and your Maintenance brochure). • Air cleaner should be inspected to

assure
proper engine "breathing".
• Battery should be fully charged.
• Wheels should be properly aligned.
• Tires should be inflated to correct pres­

sures.
Check
tire
pressures regularly - at least once a month.
• The published ENVIRONMENTAL-
PROTECTION AGENCY (EPA) and Trans­

port
Canada
mileage
estimates
may not

agree
with
your
actual
highway
mileage

which
will
vary,
depending
upon
vehicle
load
and speed,
road
and
weather
condi­

tions,
trip
length,
etc.
• Have the engine oil level checked
with

every fuel filling. Engine oil consumption
is
normal but tends to be higher when the
engine is new. The use of quality engine oil
and a correct engine oil level are essential
for vehicle performance and economical operation at all times.
