I - Tachometer*
"he red shaded area at the end of the scale indicates the maximum permissible
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-
; ne rpm drops below 1500 rpm.
~ne green shaded area on the scale snows the speed at which the engine is de-
•
eloping its most favourable torque.
3 - Normal clock*

~J
set the clock, depress the knob in the : al center and
turn.
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.

WARNING continned •
The
engine compartment
of any

motor vehicle
is a
potentially hazard­
ous
area.
Before you check anything in the engine compartment, stop
the

engine and
let it
cool down. Always
exercise extreme caution when work­
ing
one the

all of the

WARNINGS on page
97.

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
turn
cap
one

turn
to
allow excess pressure
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
have
the
cause located
and

corrected.
For more details see "Cooling system"
on

page 104.

If the
coolant gauge needle nears
the

upper end
of
the scale and the engine ap­
pears
to be
overheating,
turn
off the air

conditioner.
Do
not
install accessories
(fog
lights
or
in­
sect screens,
for
example)
on top of the

front
bumper.
They
may
restrict engine
cooling.

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
impaired,
proceed carefully to
your

nearest Volkswagen dealer or qualified
workshop to have the braking system inspected and corrected.

- Engine Oil pressure

When
the
ignition
is
turned
on, the oil
pressure warning light comes on for a bulb

check.
It
should
go out
after
the
engine
has
started.

If the
warning light does
not go out or

flashes
while driving
(above
2000
engine rpm a buzzer
will
sound simultaneously),
it

indicates,
that the oil pressure is too low.

Stop the engine immediately, check the
engine
oil
level
and add
oil, if necessary.
If engine oil level is normal, but the
light

continues to flash, do not continue to
operate the vehicle. This could damage
the engine.

Turn
the engine off and contact the nearest Volkswagen dealer for assistance.

The oil pressure warning
light
is not an indicator for low engine oil level. To

check
the oil level, always use dipstick
(see page 99).

Make
it a habit to have the engine oil
level checked
with
every
fuel filling.

TURN SIGNAL / HEADLIGHT DIMMER SWITCH LEVER
Turn signals
The turn signal indicator light flashes when you operate the lever (ignition on).
Lever up - right turn signal
Lever down - left turn signal
The turn signals are cancelled automatic­ ally when you have completed a turn (for
example when turning a corner), and the
steering wheel returns to the straight-
ahead position.
If a turn signal fails, the indicator light
flashes about twice as fast. A light bulb may have to be replaced. Headlight dimmer
With headlights on (light switch in second
stop),
you can switch to either high or low beam by pulling the lever toward the steer­ing wheel past the point of resistance.
When high beam is on, the indicator light will light up.
Headlight flasher
With headlights on or off, you can signal with your headlights (in lieu of horn), by repeatedly pulling the lever just up to the
point of resistance.
Lane changer
Move the lever up or down just to the point
of resistance - the indicator light must also flash at the same time. The lever will
return to the OFF position when released.

CRUISE
CONTROL*

JB33-509

The cruise control allows you
to
maintain a constant cruising speed above
22 mph
35
km/h),
without
actuating
the ac­

celerator pedal.

Any
manual operation, such
as
acceler­ ating, gearshifting
or
braking can be done independently
of
the cruise control.
The cruise control
is
operated
with
sliding
button
A
and pressure
button
B
positioned
at the end
of
the
turn
signal/headlight dim­ mer switch lever.
WARNING

•
To help keep the vehicle under
con­

trol do not use the cruise control when driving on winding or slippery
roads,
in heavy or in varying traffic.

•
Do not
use
the
Resume
feature when
the previously set speed is too fast for the existing traffic
conditions.

Sliding
button
A to
position
ON
actuates
the cruise control system.

Accelerate
to the
desired speed
and de­
press
button
B
(SET).
This sets
the
cruis­ing speed and stores
it in a
memory. The

foot
can then
be
taken
off the
accelerator
pedal.

With
button
B, the programmed speed can
also
be
increased. When
the
button
is
de­
pressed,
the
vehicle accelerates
until
the

knob
is
released.

If
you accelerate
- for
example when
pas­

sing
- the
previously programmed speed
will
be
resumed automatically after the ac­ celerator pedal
is
released.
When the cruise control is switched on,

do
not shift into Neutral without de­

clutching!
The engine
will
rev up imme­
diately and may
possibly
be damaged.

The cruise control
is
temporarily disen­ gaged when brake
or
clutch pedal
is de­
pressed
or
when
the
road speed drops
considerably below programmed
speed,

for example when driving uphill.

To
re-engage the system, slide
button
A to
RES
(Resume) and
the
vehicle will auto­
matically accelerate
to the
previously
programmed
speed.

A
programmed speed can
be
completely
erased
from the memory
of
the cruise
con­

trol
system
by
sliding
button
A to the
OFF position.
A
programmed speed
is
always

erased
when the ignition
is
switched
off.
WARNING
Do
not remove key from steering lock,
while you are driving or while the vehi­
cle
is rolling to a stop. The steering
wheel
will
lock when you remove the key, and
you
will
not be able to steer the

vehicle.
