General Fitting Instructions
Pressordrifttheseal in tothefull depthofthe housing ifthe housing is shouldered,orflush withthefaceofthe housing
where no shoulder is provided.
Note: Careless fitting of oil seals, which can result in damage to the seal and sealing surfaces, accounts for most
cases of failure of seals. Care in fitting is essential
if good results are to be obtained.
A3.2.7 joints And joint Faces
Remove all traces of old jointing materials prior to reassembly. Inspect joint faces for scratches or burrs and remove
with a fine file or oilstone; do not allow swarf or dirt to enter tapped holes or enclosed parts. Blow out any pipes, chan- nels or crevices with compressed air, refitting or renewing any 0-rings or seals which have been displaced by the com- pressed air.
Always use the specified gaskets. Use jointing compound only when recommended, otherwise fit joints dry. When
jointing compound is used, apply in
a thin film to metal surfaces; take great care to prevent it from entering oilways, pipes or blind tapped holes.
A3.2.8
Before removing a hose from the brake or power steering systems, thoroughly clean the end fittings and the area sur- rounding them. Obtain blanking caps beforedetaching hosefittings,sothat portscan becovered to excludedirt. Clean
the hose externally and blow through with compressed air. Examine the hose carefully for cracks, separation of plies,
security of end fittings and external damage. Reject any hose found to be faulty. When refitting the hose, ensure that
no unnecessary bends are introduced and that the hose is not twisted before or during tightening of union nuts.
Do not store hydraulic fluid in an unsealed container because it will absorb water. Fluid in this condition would be dan- gerous to use due to a lowering of its boiling point. Do not allow hydraulic fluid to be contaminated with mineral oil,
or use a container which has previously contained mineral oil.
Do not re-use fluid bled from the system. Always use clean brake fluid, or a recommended alternative, to clean the
hydraulic components. Fit a blanking cap to the hydraulic union and
a plug to its mating socket, after removal from
the vehicle, to prevent ingress of dirt. Absolute cleanliness must be observed with hydraulic components at all times.
After any work has been performed on hydraulicsystems, inspect carefully for leaks underneath the car while a second
operator applies maximum pressure to the brakes (with the engine running) and operates the steering.

A3.2.9 Metric
Bolt Identification
An IS0 metric bolt or screw, made of steel and larger than
6mm in diameter can be identified by the symbols ISOM or M embossed on top of the head (Fig. 1 ). In addition to marks
to identify the manufacturer, the head is also marked with
symbols to indicate the strength grade eg
8.8, 10.9, 12.9 or 14.9. The first figure gives the minimum strength of the bolt
material in tens of kgf / mm2. Zinc plated IS0 metric bolts
and nuts are chromate passivated and coloured greenish- khaki to gold-bronze.
A3.2.10 Metric Nut Identification
A nut with an IS0 metricthread is marked on one face (1 Fig. 2) or on one of the flats (2 Fig. 2) of the hexagon with the
strength grade symbol 8, 12 or 14. Some nuts with a
strength 4,5 or 6 are also marked and some have the metric
symbol M on the flat which is opposite to the strength grade
marking.
Aclockfacesystem is used as an alternative method of indi
- cating the strength grade (3 Fig. 2). The external chamfers
or a face of the nut is marked in a position relative to the ap-
propriate 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. Fig.

A5.3.2 Security system
Base system
Provides standard vehicle arming, ie door ajar, actuator lockstatus, trunk lid or hood ajar and passenger door unlock- ing, does not include inclination or
Intrusion sensing
Detection of intrusion into the passenger compartment by removal or breakage of any glazed area, entry via any pro- tected enclosure and unauthorized door opening detection.
Inclination (tilt) sensing
Detection of unauthorized jacking /towing.
Passive arming
Arming of the security system, excluding intrusion sensors, without audible confirmation.
Audible tones
Audible indication of driver error when attempting to arm the system, or on initiation of deadlocking.
Engine immobilization
Automatic immobilization of the engine crank facility whenever the ignition key is turned to position 0.
A5.3.3 Convenience
All close
Automatic closure of open windows and sliding roof by prolonged action of key, or remote fob transmitter after door
locking.
Headlamp convenience
Automatic illumination of headlamps for driver convenience on operation of key fob button after locking sequence
completed.
Remote trunk lid release
Automatic release of the trunk lid lock on operation of the smaller key fob button after door unlocking.
Trunk valet isolate
Independent locking of the trunk lid to eliminate unauthorized entry to the luggage compartment.
Driver seat memory select
Automatic recall of a memorized driving position on operation of the smaller key fob button.
Intrusion sensing override
Allows intrusion sensing to be disabled until the next disarm action.
A5.3.4 Alarms
There are eight possible alarm activation modes; driver's door, hood, ignition key in (ignition auxiliary position, ignition ON), inclination, inner door handle action (causing actuator status switches to operate), intrusion, passenger door and
trunk.
Any of the above conditions occurring after the vehicle is fully armed will cause full alarm state.
Any of the above conditions, except door opening, occurring
after the vehicle is fully armed and active disarming is
selected will cause full alarm state. Door opening after active disarming selection will give a 30 second audible tick
period before full alarm is entered.
Any of the above conditions occurring
after the vehicle has been passively armed will give a 30 second audible tick
period before full alarm is entered.
Activation of full alarm state causes sidelights, direction indicators, interior lights or headlamps to flash (dependant
upon market variations), the security sounder to operate and the vehicle horns to operate
(if programmed to do so).
An error tone is generated if active arming is selected with either hood or trunk open, or the transmitter is pressed with
ignition key in auxiliary position.
