Environmental Protection Precautions
It is illegal to pour used oil on to the ground, down
sewers or drains, or into water courses.
Burning of used engine oil in small space heaters or
boilers should only be considered for units of
approved design and in compliance with the
equipment manufacturer's recommendations. The
heating system must meet the regulatory standards
of HMIP for small burners of less than 0.4 MW. If in
doubt check with the appropriate local authority and/
or manufacturer of the approved appliance.
Dispose of used oil and filters through authorised
waste disposal contractors and licensed waste
disposal sites, or through the waste oil reclamation
trade. If in doubt, contact the Local Authority for
advice on disposal facilities.
Safety instructions
Whenever possible, use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
Jacking
Always use the recommended jacking points. The
recommended jacking points are shown in
theLIFTING AND TOWING sub-section of the
INFORMATION section.
Always ensure that any lifting apparatus has
sufficient load capacity for the weight to be lifted.
Ensure the vehicle is standing on level ground prior
to lifting or jacking.
Apply the handbrake and chock the wheels.
WARNING: Do not work on or under a vehicle
supported only by a jack. Always support the
vehicle on safety stands.
Do not leave tools, lifting equipment, spilt oil, etc.,
around or on the work bench area. Always keep a
clean and tidy work area.
Brake shoes and pads
Always fit the correct grade and specification of
brake linings. When renewing brake pads and brake
shoes always replace as complete axle sets only.

Self-locking bolts and screws
Self-locking bolts and screws, i.e. nylon patched or
trilobular thread can be re-used providing resistance
can be felt when the locking portion enters the
female thread.
Nylon patched bolts and screws have a locking agent
pre-applied to the threads. They are identified by the
presence of a coloured section of thread which
extends for up to 180° around the thread.
Trilobular bolts (i.e. Powerlok) have a special thread
form which creates a slight interference in the
tapped hole or threads of the nut into which it is
screwed.
DO NOT re-use self-locking fasteners in critical
locations (e.g. engine bearings, flywheel). Always
use the correct replacement self-locking nut, bolt or
screw.
DO NOT fit non self-locking fasteners in applications
where a self-locking nut, bolt or screw is specified.
Nut identification
Nut identification
A nut with an ISO metric thread is marked on one
face or on one of the flats of the hexagon with the
strength grade symbol 8, 12, or 14. Some nuts with a
strength grade 4, 5 or 6 are also marked and some
have the metric symbol M on the flat opposite the
strength grade marking.
A clock face system is sometimes used as an
alternative method of indicating the strength grade.
The external chamfers or a face of the nut is marked
in a position relative to the appropriate hour mark on
a clock face to indicate the strength grade.
A dot is used to locate the 12 o'clock position and a
dash to indicate the strength grade. If the grade is
above 12, two dots identify the 12 o'clock position.
When tightening a slotted or castellated nut, never
loosen it to insert a split pin except where
recommended as part of an adjustment. If difficulty is
experienced, alternative washers or nuts should be
selected, or the washer thickness reduced.
Where bearing pre-load is involved, nuts should be
tightened in accordance with special instructions.

Rolling road testing
General
IMPORTANT: Use a four wheel rolling road for
brake testing if possible.
The front and rear wheels cannot be driven
independently due to the viscous coupling. This
eliminates the need for differential lock by
progressively applying more torque to the rear
wheels if the front wheels start to slip.
DO NOT attempt to drive individual wheels with
vehicle supported on floor jacks or stands.
Four wheel rolling road
Provided that front and rear rollers are rotating at
identical speeds and that normal workshop safety
standards are applied, there is no speed restriction
during testing, except any that may apply to the tyres.
Before testing a vehicle with anti-lock brakes on a
four wheel rolling road, disconnect the ABS
modulator. The ABS function will not work, the ABS
warning light will illuminate. Normal braking will be
available.
Two wheel rolling road
ABS will not function on a two wheel rolling road. The
ABS light will illuminate during testing. Normal
braking will be available.
If brake testing on a two wheel rolling road is
necessary, the following precautions should be
taken:
lpropeller shaft to the rear axle is removed/
disconnected;
lneutral selected in gearbox;
lhill descent control not selected.
When checking brakes, run engine at idle speed to
maintain servo vacuum.

GENERAL INFORMATION
03-21
It should be noted that these precautions are not
restricted to operations performed when servicing
the SRS system, the same care should be exercised
when working on ancillary systems and components
located in the vicinity of SRS components; these
include but are not limited to:
lSteering system – steering wheel airbag,
rotary coupler.
lFront fascia – passenger front airbag (where
fitted); SRS DCU behind centre console, on
transmission tunnel under the HeVAC system.
lFront seats – seat belt pre-tensioners, integral
with seat belt buckle assembly.
lElectrical system – SRS harnesses, link leads
and connectors.
Making the SRS system safe
Before working on or in the vicinity of SRS
components, ensure the system is rendered safe by
performing the following procedures:
lRemove the ignition key from the ignition switch.
lDisconnect both battery leads, earth lead first.
lWait 10 minutes for the SRS DCU back-up
power circuit to discharge.
The SRS system uses energy reserve capacitors
that keep the system active in the event of electrical
supply failure under crash conditions. It is necessary
to allow the capacitor sufficient time to discharge (10
minutes) in order to avoid the risk of accidental
deployment.
WARNING: Always disconnect both battery leads
before beginning work on the SRS system.
Disconnect the negative battery lead first. Never
reverse connect the battery.Installation
In order to assure system integrity, it is essential that
the SRS system is regularly checked and maintained
so that it is ready for effective operation in the event
of a collision. Carefully inspect SRS components
before installation. Do not install a part that shows
signs of being dropped or improperly handled, such
as dents, cracks or deformation.
WARNING: The integrity of SRS system
components is critical for safety reasons. Ensure
the following precautions are always adhered to:
lNever install used SRS components from
another vehicle or attempt to repair an SRS
component.
lWhen repairing an SRS system only use
genuine new parts.
lNever apply electrical power to an SRS
component unless instructed to do so as
part of an approved test procedure.
lSpecial Torx bolts are necessary for
installing the airbag module — do not use
other bolts. Ensure bolts are tightened to the
correct torque.
lAlways use new fixings when replacing an
SRS component.
lEnsure the SRS Diagnostic Control Unit
(DCU) is always installed correctly. There
must not be any gap between the DCU and
the bracket to which it is mounted. An
incorrectly mounted DCU could cause the
system to malfunction.
CAUTION: Ensure SRS components are not
contaminated with oil, grease, detergent or
water.
Ensure that SRS component fixings are correctly
positioned and torqued during service and repair.
CAUTION: Torque wrenches should be regularly
checked for accuracy to ensure that all fixings
are tightened to the correct torque.
If you suspect an airbag assembly could be
defective, install a new unit and dispose of the old
unit. Manually deploy the old unit before disposal.

SRS Harnesses and Connectors
CAUTION: Always observe the following
precautions with regards to SRS system
electrical wiring:
lNever attempt to modify, splice or repair
SRS wiring.
lNever install electronic equipment (such as
a mobile telephone, two-way radio or in-car
entertainment system) in such a way that it
could generate electrical interference in the
airbag harness. Seek specialist advice when
installing such equipment.
NOTE: SRS system wiring can be identified by a
special yellow outer sleeve protecting the wires
(black with yellow stripe protective coverings are
sometimes used).
WARNING: Always ensure SRS wiring is routed
correctly. Be careful to avoid trapping or
pinching the SRS wiring. Do not leave the
connectors hanging loose or allow SRS
components to hang from their harnesses. Look
for possible points of chafing.CAUTION: Ensure all SRS harness connectors
are mated correctly and securely fastened. Do
not leave the connectors hanging loose.
Rotary Coupler
CAUTION: Always follow the procedure for fitting
and checking the rotary coupler as instructed in
the SRS repairs section. Comply with all safety
and installation procedures to ensure the system
functions correctly. Observe the following
precautions:
lDo not install a rotary coupler if it is
suspected to be defective.
lDo not attempt to service, modify or repair a
rotary coupler.
lDo not cut, splice or modify the wires
attached to the rotary coupler.
lAlways ensure the rotary coupler
connectors are mated correctly and securely
fastened.
lAlways ensure the battery is disconnected
before working on the rotary coupler.
lDo not unlock and rotate the rotary coupler
when it is removed from the vehicle.
lDo not turn the road wheels when the rotary
coupler is removed from the vehicle.
lAlways ensure the rotary coupler is removed
and installed in its centred position and with
the front road wheels in the straight ahead
position - refer to the SRS repair section for
the correct removal and installation
procedure.
lIf a new rotary coupler is being installed,
ensure the locking tab holding the coupler's
rotational position is not broken; units with a
broken locking tab should not be used.

VEHICLE RECOVERY
Observe the following procedures for vehicle towing
after a collision has taken place:
Towing – SRS components not deployed
Normal towing procedures are unlikely to cause an
SRS module to deploy. However, as a precaution,
switch the ignition off and then disconnect both
battery leads. Disconnect the negative '-' lead first.
Towing – SRS components deployed
Once the driver's airbag has been deployed, the
vehicle must have a front suspended tow. However,
as a precaution, switch the ignition off and then
disconnect both battery leads. Disconnect the
negative '-' lead first.

GENERAL INFORMATION

SRS component replacement policy
The following information details the policy for
replacement of SRS components; either as a result
of a vehicle accident or as a result of vehicle age.
Impacts which do not deploy the airbags or seat
belt pre-tensioners
Check for structural damage in the area of the
impact, paying particular attention to bumper
armatures, longitudinals, crash cans and bracketry.
Impacts which deploy the airbags and/or seat
belt pre-tensioners
The inspection and replacement policy is dependent
on the type and severity of the crash condition. The
following guidelines are the minimum that should be
exercised as a result of the deployment of specific
SRS components.
Front airbag/ seat belt pre-tensioner deployment
(driver and passenger)
If the front airbags and/or seat belt pre-tensioners are
deployed as a result of a front, front angled or side
impact, the following parts must be replaced:
lDriver airbag module
lPassenger airbag module (where fitted)
lSRS flyleads
lSRS DCU
lRotary coupler
lFront seat belt pre-tensioners
In addition, the following should be inspected for
damage and replaced as necessary:
lFront seat belt and buckle tongue (anchorage
points, webbing etc.)
lFascia moulding adjacent to passenger airbag
module (where fitted)
lSteering wheel (if damage is evident)
lFront seat frames and head restraints (if there is
evidence of damage to the seat frame or
cushion pan)
lSteering column (if adjustment is lost or there
are signs of collapse)
lFront seat belt height adjusters on 'BC' posts (5
door models only)
lRear seat belts and seat belt buckles (webbing,
buckle covers, body anchorage and tongue
latching function)Rear Impact
If the seat belt pre-tensioners are deployed during a
rear impact, the following components must be
replaced:
lSeat belt pre-tensioners
lFront and rear automatic seat belt assemblies
used during an impact.
lSRS DCU
In addition, the following components should be
inspected for damage and replaced as necessary:
lFront seat frames
lFront seat belts and buckle (retractors,
webbing, tongue latching, buckle covers, body
anchorages and 'D' loops)
lSeat belt height adjusters (5 door models only)
lRear seat belts and seat belt buckles (webbing,
buckle covers, body anchorage and tongue
latching function)
Periodic replacement of SRS components
The performance of the propellants within airbags
and seat belt pre-tensioners will deteriorate over a
period of time. As a result, it is essential that the
airbags and seat belt pre-tensioners are periodically
replaced to maintain occupant safety. Airbags, seat
belt pre-tensioners and the rotary coupler should be
replaced at the recommended intervals.
