Changing bulbs

Before
starting to replace a bulb, switch off
the light concerned.

Do
not touch the glass part of the new bulb

with
bare fingers because the finger marks
left
on the glass evaporate when the bulb

becomes
hot, the vapour settles on the re­
flector and dims it.

Always
use the same type of bulb. The
des­

ignation is marked on the base of the bulb
or on the
glass.

It is advisable to always a carry a box of

spare
bulbs in the vehicle. These can be ob­
tained from Volkswagen dealers. It should contain at least the following bulbs which

Tow
starting/towing

General
notes

• "owing eyes are provided on the
right
under
front
and rear bumpers.

Tow-ropes
or bars should be attached at

these
points only.

On
vehicles
with
a factory
fitted
towing bracket a towing eye is not fitted. On those

vehicles
the towing bracket can be used for
towing.
• The tow-rope should be slightly elastic to reduce the risk of damage to both ve­
hicles.
It is advisable to use synthetic fibre

ropes,
or ropes of similar elastic material. It
is
however
safer
to use a
tow-bar!

Avoid
excessive towing
effort
and do not

jerk.
During towing operations on other than
surfaced
roads there is always the danger

that
the attachment points will be over­
loaded
and damaged.
•
Before
trying
to
start
engine
by
towing,
the
battery
from
another
ve­
hicle
should be used for
starting
if
possible - see previous page. If the
vehicle
has to be tow
started

or
towed
at any
time,
the
following

must
be noted:
•
Check
whether there are any local traffic regulations concerning the towing of ve­

hicles.

• Both drivers must be familiar
with
tow­ ing procedures. Inexperienced drivers

should
not attempt to tow start or tow.
• When using a tow-rope the driver of the towing vehicle must engage the clutch very gently when moving off and changing gear.
• The driver of the vehicle being towed must ensure
that
the tow-rope is always

taut.
• The emergency lights must be switchec
on on both vehicles - unless local regula­
tions differ.
• Turn ignition key to "Drive" position sc
that
the steering wheel is free and the
turr
signals,
horn, and, if necessary, the wind­

screen
wiper and washer can be
used.

• As the brake servo only works when the engine is running, considerably more pres­

sure
is required on the brake pedal when the
engine is not running.
• On vehicles
with
power assisted steer­ ing more force is required to
turn
steering
wheel when engine is not running.
• When there is no lubricant in the manua or automatic gearbox, the vehicle may only

be
towed
with
driving wheels lifted.

ROUTINE
CHECKS
WHEN
FILLING
THE TANKS
n order to ensure
that
your vehicle remains ready for the road at all
times between Inspections you should carry out a few checks reg-
jlarly
- preferably when filling the tank.
Attention

Take
particular
care
when
working
in the
engine
compartment
- see
page
95.

We
have listed the most important points to be checked here. How
to open the bonnet is explained on page 94. 1 -
Coolant
reservoir
(expansion
tank)

Attention
Do not
open
expansion
tank
when
engine
is hot -

danger
of scalding!
If the level is below the min. mark, top it up
with
coolant additive G 11 V 8 B and water - see page 101. When unavoidable plain water

can
be used temporarily.
2 -
Brake
fluid
reservoir

The fluid level must always be between the min. and max. marks

-see
page 104.
3 - Engine oil
level
Every
engine
uses
a certain amount of oil. If the level is too low it

can
lead to serious engine damage. For this reason the level must be checked regularly - see page 97.
4- Engine oil
filler
opening

The approved types of oil are given on page 96.
5 -
Windscreen
washer
container

Always
fill
with
water and a glass cleaner. Think about frost precau­
tions in winter.
