Supplemental Restraint System - Air Bag Supplemental Restraint System
(SRS)
Description and Operation
Supplementary Restraint Air Bag System

Airbag/SRS units provided for driver and fro nt seat passemger protection, are installed in the center of the steering wheel,
the passenger side fascia and the oute r wing of each front seat. A single point sensing unit (SPS) mounted on the
transmission tunnel, below the ra dio, provides fully electronic impact sensing, control and diagnostics for the front airbags
Deployment of each side airbag is initia ted by a side impact sensing module (SISM) installed in the adjacent 'B' post. Each
SISM senses and electronically processes a crash pulse and if this exceeds the 'must fire' threshold, transmits a fire signal
to the SPS unit. The SPS unit monitors wh ole vehicle motion and on confirmation of a crash condition, transmits a firing
current pulse to the appropriate airbags. In the event of a side only impact, the SPS will send a current pulse to the airbag
on the struck only. Neither th e non-struck side airbag nor the frontal restraint system will be deployed under these
conditions. The airbag system can only be activated wh en the ignition switch is in position II or III.

The body is pre-treated to ensure high resistance to corrosion and stone chip dama ge. Prior to the first major pre-treatment process, the body shell is high-pressure washed to remove any metal dust and residual oil.
The first major pre-treatment process consists of phosphate and electro-paint deposition, which together with zinc coating,
forms the basis of the corrosion protection. This process includes high pressure knock-off, alkali de-greasing, zinc phosphate
conversion of body steel (dissolving iron and coating with zinc phosphate crystals), trivalent chrome rinsing and
demineralized water rinsing, seal ing all chemicals and impurities.
Both dip and spray techniques are employed and the bodies are submerged to the waistline during the first and third rinses
of the main phosphate clean. Chemical strengths and soluti on temperatures are continuously monitored and accurately
controlled throughout the process.
An 80% water primer is then cathodic elec tro-deposition applied to the thoroughly cleansed bodies in a uniform 'sag-free'
film 18 to 32 micron thick. Optimum durabi lity of the electroprimer is achieved by finally curing in a stoving oven at 165 °C
for a period of 20 minutes.
All underbody seams of the fully primed bo dies are then manually sealed, to prevent water and dust ingress into the vehicle
and to enhance corrosion protection.
An 800 to 1000 g/m2 PVC coating is semi-automatic airless sp ray applied to the underside of the main floor panels, trunk
floor and rear wheel arches (ref. illustration above).
The upper panels of primed and external ly sealed bodyshells are next lightly scuffed to remove imperfections and a PVC
coating is applied to all internal seams by an airless spray technique. A PVC bead seal is also applied to the doors, hood and
trunk clinch joints.
Following anti-corrosion, sealing and primin g treatment, the bodies enter the first stage of 'cosmetic' painting. This consists
of the application of two coats of a highly chip resistant po lyester surfacer, employing high voltage electrostatic 'spinning
bells', to achieve a final film thickness of 35 to 50 micron. Between surfacer coats, a polyurethane coat is automatically
applied to the sills to impart even greater resistance to stone chipping.
All interior panels are then painted us ing a color keyed sealer, wet-on-wet wi th a surfacer material, after which the
bodyshells are stoved at 160 °C for a period of 20 minutes. Further protection agai nst corrosion is provided by a medium
solids black pigmented wax which is airless spray applied to vehicle undersides.
Wax Injected Box Sections
Critical body box-sections are si milarly protected by spray injecting a high solids wax. This is then re-flowed at 70 to 90 °C
to achieve optimum seam/joint penetratio n and form a resilient and durable internal coating (ref. illustration above).
After full wet sanding, rinsing and drying to provide a good su bstrate, a color-keyed semi-matt sealer co at is applied using
electrostatic bells to achieve a film build of 25 to 35 micron . The bodies are then stoved for a further 20 minutes at a
temperature of 145 °C and subjected to a local 'seek-and-find' de -nib operation prior to the final two coat process. The final
top coat finish is achieved by using poly ester base coat colors and an acrylic sag resistant clear coat. This clear over base
(COB) process produces a high gloss, durabl e paint finish with a film thickness of 50 to 65 micron, which is finally cured at a
temperature of 135°C for 20 minutes.
The Munsell three dimensional system of color management is em ployed to achieve highly accurate control of vehicle colors.
This system ensures that paint pigmentations are accurately maintained and facilitates vigorous final checking of finished
vehicles for color match. The hu e of individual panels such as trunk lids, doors and hoods is in some instances adjusted to
offset the effects of differing light angles. Where applicable, coachlines are manually applied and radiant heat cured on the
completed and valeted vehicle prior to hand spray applic ation of a protective wax coat.
Introduction
All repairs, whether structural or cosmetic must return the vehicle to the original manufactured condition with regard to
occupant safety, dimensional accuracy, fi nish and corrosion protection, and ensure continuation of the Paint Surface and
Corrosion warranty where applicable.
Similarly, repaired vehicles must be fu lly checked, and where appropriate reset, with regard to steering, suspension,
braking, and occupant restraint systems.

Generally, resistance spot welding equipment used in the motor vehicle repair industry does not produce welds of equivalent strength to those achieved during manufactu re. The expression 'single row of resistance spot welds' indicates that the spots
should be spaced on a pitch of 19mm to 25mm, which normally results in mo re spot welds than those produced in the
original factory joint.
Resistance spot welds should be removed using a resistance spot weld cutter. If the new joint is to be MIG plug welded, old
resistance spot welds should be cut from the panel to be reta ined and the resulting holes used for plug welding. Suitable
holes may also be drilled or punched; 8,0 mm dia for sect ions up to 1,6 mm, and 10,0 mm dia for thicker sections.
PLASTICS-EXPLANATORY NOTES
Plastic component and trim materials
This table, in conjunction with the illu strations on the following pages will enable rapid identification of the particular
material of any major plastic part.
• NOTE: Only those components suitable for economic reclamation are identified.
Plastics - Handling Notes
The exterior panel temperature of a vehicle must not exceed 95°C at any time and may only be held at this level for a
maximum of two hours. Similarly, interior vehicle temperatur e must be limited to 86°C for a maximum duration of two
hours. Exposure to temperatures above those specified may result in distorted or permanently damaged components. If
there is doubt concerning temperature limitations, components that may be adversel y affected by exposure to heat should
be removed from the vehicle.
Plastic components that become greasy may be clea ned with an 'SBP 3' spirit wipe, or equivalent.
Recycled Materials
Any of the materials listed in this section, may be recycled provided that they ar e not contaminated by other incompatible
plastics or metals. For instan ce, the air conditioning unit case, manufactur ed from PP (polypropylene), must be separated
from the heater matrix, evaporator, contro l devices (electronic and mechanical) and all fixings before it can be considered
for recycling. After removal, the case mu st only be placed for disposal with materials of the same generic type. Bumper
cover assemblies similarly have side arma tures of dissimilar materials rivetted to them, these together with their fixings
must be removed prior to recy cling. Components manufactured from 'blended' materials must not be recycled with pure
materials. For example do not mix PC/ABS (wheel trim) with ABS ('B' pillar upper trim).

BODY ALIGNMENT
The Body Dimensions Plan, and Body Dimensions Side View, provide specified BIW dimensions to facilitate damage
assessment and location of replacemen t parts. These dimensions must be strictly applied when used for damage
assessment, component location or post repair verification.
• NOTE: The right-hand side is always looking towards the front, from the rear of the vehicle.
The nominated plan view master datums are on the right-hand side of the body with the left-hand datums dimensioned
from them. Right-hand datums must therefore be known to be correct before any other cross-car dimensions are checked.
