The bodyshell and underframe on all
models is of all-steel welded construction,
incorporating progressive crumple zones at
the front and rear, and a rigid centre safety
cell. The bulkhead behind the engine
compartment incorporates crash grooves
which determine its energy-absorption
characteristics, and special beams to prevent
the intrusion of the front wheels into the
passenger compartment during a serious
accident. All passenger doors incorporate
side impact bars.
All sheet metal surfaces which are prone tocorrosion are galvanized. The painting
process includes a base colour which closely
matches the final topcoat, so that any stone
damage is not noticeable.
Hatchback, Saloon and Estate versions are
available. The front section of the vehicle up to
the “B” pillar is identical on all models.
Automatic seat belts are fitted to all models,
and the front seat belt stalks are mounted on
automatic tensioners (also known as
“grabbers”) (see illustration). In the event of a
serious front impact, a spring mass sensor
releases a coil spring which pulls the stalk
buckle downwards and tensions the seat belt.
It is not possible to reset the tensioner once
fired, and it must therefore be renewed.
In the UK, central locking is standard on all

3Peel back the protective paper from the
rear face of the new moulding or emblem.
Carefully fit it into position on the panel
concerned, but take care not to touch the
adhesive. When in position, apply hand
pressure to the moulding/emblem for a short
period, to ensure maximum adhesion to the
panel.1The sunroof should operate freely, without
sticking or binding, as it is opened and
closed. When in the closed position, check
that the panel is flush with the surrounding
roof panel.
2If adjustment is required, open the sun
blind, but leave the glass panel shut. Unscrew
and remove the three lower frame-to-glass
panel retaining screws. Slide the lower frame
back into the roof.
3Loosen the central and front securing
screws. Adjust the glass roof panel so that it is
flush at its front edge with the roof panel, then
retighten the securing screws.
4Pull the lower frame forwards, and insert
and tighten its retaining screws to complete.

Warning: Before carrying out any
work on the electrical system,
read through the precautions
given in “Safety first!” at the beginning of
this manual.The electrical system is of 12-volt negative
earth type. Power for the lights and all
electrical accessories is supplied by a
lead/acid battery which is charged by the
alternator.
This Chapter covers repair and service
procedures for the various electrical
components not associated with the engine.
Information on the battery, ignition system,alternator, and starter motor can be found in
Chapter 5.
All models are fitted with a driver’s air bag,
which is designed to prevent serious chest
and head injuries to the driver during an
accident. A similar bag for the front seat
passenger is also available (see illustration).
The sensor and electronic unit for the air bag
is located next to the steering column inside
the vehicle, and contains a back-up capacitor,
crash sensor, decelerometer, safety sensor,
integrated circuit and microprocessor (see
illustration). The air bag is inflated by a gas
generator, which forces the bag out of the
module cover in the centre of the steering
wheel. A “clock spring” ensures that a good
electrical connection is maintained with the air
bag at all times - as the steering wheel is
turned in each direction, the spring winds and
unwinds.
All UK models are fitted with an alarm
system incorporating a movement sensor and
ignition immobiliser. On Saloon and
Hatchback models, the alarm system horn is
located on the left-hand side of the luggage

Introduction
A selection of good tools is a fundamental
requirement for anyone contemplating the
maintenance and repair of a motor vehicle.
For the owner who does not possess any,
their purchase will prove a considerable
expense, offsetting some of the savings made
by doing-it-yourself. However, provided that
the tools purchased meet the relevant national
safety standards and are of good quality, they
will last for many years and prove an
extremely worthwhile investment.
To help the average owner to decide which
tools are needed to carry out the various tasks
detailed in this manual, we have compiled
three lists of tools under the following
headings: Maintenance and minor repair,
Repair and overhaul, and Special. Newcomers
to practical mechanics should start off with
the Maintenance and minor repairtool kit, and
confine themselves to the simpler jobs around
the vehicle. Then, as confidence and
experience grow, more difficult tasks can be
undertaken, with extra tools being purchased
as, and when, they are needed. In this way, a
Maintenance and minor repairtool kit can be
built up into a Repair and overhaultool kit over
a considerable period of time, without any
major cash outlays. The experienced do-it-
yourselfer will have a tool kit good enough for
most repair and overhaul procedures, and will
add tools from the Specialcategory when it is
felt that the expense is justified by the amount
of use to which these tools will be put.
Maintenance and minor repair
tool kit
The tools given in this list should be
considered as a minimum requirement if
routine maintenance, servicing and minor
repair operations are to be undertaken. We
recommend the purchase of combination
spanners (ring one end, open-ended the
other); although more expensive than open-
ended ones, they do give the advantages of
both types of spanner.
MCombination spanners:
Metric - 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,
19, 21, 22, 24 & 26 mm
MAdjustable spanner - 35 mm jaw (approx)
MTransmission drain plug key (Allen type)
MSet of feeler gauges
MSpark plug spanner (with rubber insert)
MSpark plug gap adjustment tool
MBrake adjuster spanner (where applicable)
MBrake bleed nipple spanner
MScrewdrivers:

Cross blade - approx 100 mm long x
6 mm dia
MCombination pliers
MHacksaw (junior)
MTyre pump
MTyre pressure gauge
MOil can
MOil filter removal tool
MFine emery cloth
MWire brush (small)
MFunnel (medium size)
Repair and overhaul tool kit
These tools are virtually essential for
anyone undertaking any major repairs to a
motor vehicle, and are additional to those
given in the Maintenance and minor repairlist.
Included in this list is a comprehensive set of
sockets. Although these are expensive, they
will be found invaluable as they are so
versatile - particularly if various drives are
included in the set. We recommend the half-
inch square-drive type, as this can be used
with most proprietary torque wrenches. If you
cannot afford a socket set, even bought
piecemeal, then inexpensive tubular box
spanners are a useful alternative.
The tools in this list will occasionally need to
be supplemented by tools from the Special
list:
MSockets (or box spanners) to cover range in

sockets) (see illustration)

Special tools
The tools in this list are those which are not
used regularly, are expensive to buy, or which
need to be used in accordance with their
manufacturers’ instructions. Unless relatively
difficult mechanical jobs are undertaken
frequently, it will not be economic to buy
many of these tools. Where this is the case,
you could consider clubbing together with
friends (or joining a motorists’ club) to make a
joint purchase, or borrowing the tools against
a deposit from a local garage or tool hire
specialist. It is worth noting that many of the
larger DIY superstores now carry a large range
of special tools for hire at modest rates.
The following list contains only those tools
and instruments freely available to the public,
and not those special tools produced by the
vehicle manufacturer specifically for its dealer
network. You will find occasional references
to these manufacturers’ special tools in the
text of this manual. Generally, an alternative
method of doing the job without the vehicle
manufacturers’ special tool is given. However,
sometimes there is no alternative to using
them. Where this is the case and the relevant
tool cannot be bought or borrowed, you will
have to entrust the work to a franchised
garage.

Whenever servicing, repair or overhaul work
is carried out on the car or its components, it
is necessary to observe the following
procedures and instructions. This will assist in
carrying out the operation efficiently and to a
professional standard of workmanship.
Joint mating faces and gaskets
When separating components at their
mating faces, never insert screwdrivers or
similar implements into the joint between the
faces in order to prise them apart. This can
cause severe damage which results in oil
leaks, coolant leaks, etc upon reassembly.
Separation is usually achieved by tapping
along the joint with a soft-faced hammer in
order to break the seal. However, note that
this method may not be suitable where
dowels are used for component location.
Where a gasket is used between the mating
faces of two components, ensure that it is
renewed on reassembly, and fit it dry unless
otherwise stated in the repair procedure.
Make sure that the mating faces are clean and
dry, with all traces of old gasket removed.
When cleaning a joint face, use a tool which is
not likely to score or damage the face, and
remove any burrs or nicks with an oilstone or
fine file.
Make sure that tapped holes are cleaned
with a pipe cleaner, and keep them free of
jointing compound, if this is being used,
unless specifically instructed otherwise.
Ensure that all orifices, channels or pipes
are clear, and blow through them, preferably
using compressed air.
Oil seals
Oil seals can be removed by levering them
out with a wide flat-bladed screwdriver or
similar implement. Alternatively, a number of
self-tapping screws may be screwed into the
seal, and these used as a purchase for pliers
or some similar device in order to pull the seal
free.
Whenever an oil seal is removed from its
working location, either individually or as part
of an assembly, it should be renewed.
The very fine sealing lip of the seal is easily
damaged, and will not seal if the surface it
contacts is not completely clean and free from
scratches, nicks or grooves.
Protect the lips of the seal from any surface
which may damage them in the course of
fitting. Use tape or a conical sleeve where
possible. Lubricate the seal lips with oil before
fitting and, on dual-lipped seals, fill the space
between the lips with grease.
Unless otherwise stated, oil seals must be
fitted with their sealing lips toward the
lubricant to be sealed.
Use a tubular drift or block of wood of the
appropriate size to install the seal and, if the
seal housing is shouldered, drive the seal
down to the shoulder. If the seal housing is
unshouldered, the seal should be fitted with
its face flush with the housing top face (unless
otherwise instructed).
Screw threads and fastenings
Seized nuts, bolts and screws are quite a
common occurrence where corrosion has set
in, and the use of penetrating oil or releasing
fluid will often overcome this problem if the
offending item is soaked for a while before
attempting to release it. The use of an impact
driver may also provide a means of releasing
such stubborn fastening devices, when used
in conjunction with the appropriate
screwdriver bit or socket. If none of these
methods works, it may be necessary to resort
to the careful application of heat, or the use of
a hacksaw or nut splitter device.
Studs are usually removed by locking two
nuts together on the threaded part, and then
using a spanner on the lower nut to unscrew
the stud. Studs or bolts which have broken off
below the surface of the component in which
they are mounted can sometimes be removed
using a proprietary stud extractor. Always
ensure that a blind tapped hole is completely
free from oil, grease, water or other fluid
before installing the bolt or stud. Failure to do
this could cause the housing to crack due to
the hydraulic action of the bolt or stud as it is
screwed in.
When tightening a castellated nut to accept
a split pin, tighten the nut to the specified
torque, where applicable, and then tighten
further to the next split pin hole. Never slacken
the nut to align the split pin hole, unless stated
in the repair procedure.
When checking or retightening a nut or bolt
to a specified torque setting, slacken the nut
or bolt by a quarter of a turn, and then
retighten to the specified setting. However,
this should not be attempted where angular
tightening has been used.
For some screw fastenings, notably cylinder
head bolts or nuts, torque wrench settings are
no longer specified for the latter stages of
tightening, “angle-tightening” being called up
instead. Typically, a fairly low torque wrench
setting will be applied to the bolts/nuts in
the correct sequence, followed by one or
more stages of tightening through specified
angles.
Locknuts, locktabs and washers
Any fastening which will rotate against a
component or housing in the course of
tightening should always have a washer
between it and the relevant component or
housing.
Spring or split washers should always be
renewed when they are used to lock a critical
component such as a big-end bearing
retaining bolt or nut. Locktabs which are
folded over to retain a nut or bolt should
always be renewed.
Self-locking nuts can be re-used in non-
critical areas, providing resistance can be felt
when the locking portion passes over the bolt
or stud thread. However, it should be noted
that self-locking stiffnuts tend to lose theireffectiveness after long periods of use, and in
such cases should be renewed as a matter of
course.
Split pins must always be replaced with
new ones of the correct size for the hole.
When thread-locking compound is found
on the threads of a fastener which is to be re-
used, it should be cleaned off with a wire
brush and solvent, and fresh compound
applied on reassembly.
Special tools
Some repair procedures in this manual
entail the use of special tools such as a press,
two or three-legged pullers, spring
compressors, etc. Wherever possible, suitable
readily-available alternatives to the
manufacturer’s special tools are described,
and are shown in use. Unless you are highly-
skilled and have a thorough understanding of
the procedures described, never attempt to
bypass the use of any special tool when the
procedure described specifies its use. Not
only is there a very great risk of personal
injury, but expensive damage could be
caused to the components involved.
Environmental considerations
When disposing of used engine oil, brake
fluid, antifreeze, etc, give due consideration to
any detrimental environmental effects. Do not,
for instance, pour any of the above liquids
down drains into the general sewage system,
or onto the ground to soak away. Many local
council refuse tips provide a facility for waste
oil disposal, as do some garages. If none of
these facilities are available, consult your local
Environmental Health Department for further
advice.
With the universal tightening-up of
legislation regarding the emission of
environmentally-harmful substances from
motor vehicles, most current vehicles have
tamperproof devices fitted to the main
adjustment points of the fuel system. These
devices are primarily designed to prevent
unqualified persons from adjusting the fuel/air
mixture, with the chance of a consequent
increase in toxic emissions. If such devices
are encountered during servicing or overhaul,
they should, wherever possible, be renewed
or refitted in accordance with the vehicle
manufacturer’s requirements or current
legislation.
Note: It is
antisocial and
illegal to dump
oil down the
drain. To find

your local oil
recycling
bank, call this
