9-36 BODY SERVICE
Sealer is applied to the specific joints of a vehicle dur-
ing production. The sealer is intended to prevent dust
from entering the vehicle and serves also as an anti-
corrosion barrier. The sealer is applied to the door and
hood hem areas and between panels. Correct and re-
seal the originally sealed joints if damaged. Reseal
the attaching joints of a new replacement panel and
reseal the hem area of a replacement door or hood.
Use a quality sealer to seal the flanged joints, overlap
joints and seams. The sealer must have flexible char-
acteristics and paintability after it's applied to repair
areas.
For the sealer to fill open joints, use caulking material.
Select a sealer in conformance with the place and
purpose of a specific use. Observe the manufactur-
er's label-stand instructions when using the sealer.
In many cases, repaired places require color painting.
When this is required, follow the ordinary techniques
specified for the finish preparation, color painting and
undercoating build-up.
Rust proof wax, a penetrative compound, is applied
to the metal-to-metal surfaces (door and side sill in-
sides) where it is difficult to use ordinary undercoating
material for coating. Therefore, when selecting the
rust proof wax, it may be the penetrative type.
During the undercoating (vinyl coating) application,
care should be taken that sealer is not applied to the
engine-related parts and shock absorber mounting or
rotating parts. Following the under coating, make
sure that body drain holes are kept open.
he sequence of the application steps of the anti-corro-
sion materials are as follows:
1) Clean and prepare the metal surface.
2) Apply primer.
3) Apply sealer (all joints sealed originally).
4) Apply color in areas where color is required such
as hem flanges, exposed joints and under body
components.
5) Apply anticorrosion compound (penetrative wax).
6) Apply undercoating (rust proof material).
PAINT AND COATINGS
ANTI-CORROSION TREATMENT
WARNING:
Standard shop practices, particularly eye
protection, should be followed during the per-
formance of the below-itemized operations to
avoid personal injury.
As rust proof treatment, steel sheets are given corro-
sion resistance on the interior and / or exterior.
These corrosion resistance steel sheet materials are
called one of two-side galvanized steel sheets.
It is for the sake of rust protection that these materials
are selected and given a variety of treatments as de-
scribed blow.
1) Steel sheets are treated with cathodic electroprim-
er which is excellent in corrosion resistance.
2) Rust proof wax coatings are applied to door and
side sill insides where moisture is liable to stay.
3) Vinyl coating is applied to body underside and
wheel housing inside.
4) Sealer is applied to door hem, engine compart-
ment steel sheet-to-steel sheet joint, and the like
portions to prevent water penetration and resulting
in rust occurrence.
In panel replacement or collision damage repair, leav-
ing the relevant area untreated as it is in any operation
which does disturb the above-mentioned rust proof
treatment will cause corrosion to that area. Therefore,
it is the essential function of any repair operation to
correctly recoat the related surfaces of the relevant
area.
All the metal panels are coated with metal condition-
ers and primer coating during vehicle production. Fol-
lowing the repair and / or replacement parts installa-
tion, every accessible bare metal surface should be
cleaned and coated with rust proof primer. Perform
this operation prior to the application of sealer and
rust proof wax coating.

YH4
GRAND
VITARA
When the welding or heating operation causes the
original galvanization or other anticorrosive materials
to be burnt, the interior and under-body panel sur-
faces must be cleaned.
Removal of residues of the burning should be carried
out carefully when the relevant place has boxtype
construction or has shape which limits the access to
the interior surfaces. In general, the following method
can be used satisfactorily for the removal of those res-
idues.Scrape the accessible places. If a standard putty knife
or scraper does not fit to the elevant place, consider
to use a more flexible scraper to a place narrowly en-
closed by sheet metals.
A jet of compressed air can remove most residues,
and is effective to limited areas.
However, this type of operation absolutely requires
eye protection.
BODY SERVICE 9-37
The metal service replacement parts (or assemblies)
are coated with electro-deposition primer.
For the proper adhesion of a paint, the following finish
process (refinish steps) becomes necessary.
1) Use wax or grease-removing solvent to clean the
part.
2) Use a wet or dry sand-paper (No. 400) to polish the
panel lightly. Do not polish it forcibly to produce any
scratch. Clean the part again.
3) If factory-applied primer coating is cut through to
the bare metal, apply metal conditioner to the bare
metal exposed to open air. As for method of use of
the metal conditioner, follow directions on the con-
tainer.
4) Apply primer-surfacer to the part completely dry
before starting sand-paper polishing. As for drying
time, follow directions advised on the primer-sur-
facer container.
5) Use a wet or dry sand-paper (No. 400) and water
to polish the panel lightly.
6) Wash the part again.
7) Apply color, coating to the part.
8) Different paints demand different drying methods.
Hence, follow directions advised on the pertinent
paint container.9) When lacquer coating (quick-drying paint coat-
ing) is applied, dry coated surface and polish it
with compound.
In the case of the melamine or acrylic coating,
compound polishing can be omitted after drying.
10) If the case of lacquer coating, wax should not be
applied to coated surface until the surface has
dried completely (for approx. two months).
Before replacing exterior parts or assemblies, check
paint conditions of all the covered or hidden interior
surfaces. If any rust scale is found at these places,
proceed as follows:
1) Use a proper wire brush, adhesive or liquid rust re-
moving agent to remove rust. As for the method of
use, follow directions advised for respecitve mate-
rials.
2) If necessary, wash parts with detergent, rinse, and
dry them.
3) Before installing exterior body parts, apply anticor-
rosive compound to all cleaner surfaces of exterior
body parts. Also, apply anticorrosive compound to
inner surfaces of exterior body parts to be
installed.

GENERAL DESCRIPTION
Seat belt with ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the web-
bing from being pulled out of the retractor any further) when any of the following items is detected as exceeding
each set value; speed at which the webbing is pulled out of the retractor, acceleration or deceleration of the vehicle
speed, and inclination.
Seat belt with A-ELR
The automatic and emergency locking retractor (A-ELR) works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further, unless it is wound all the way back into the retractor, which
releases the lock and allows the webbing to be pulled out.
Driver and front passenger side air bags
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front collision
with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supplement
protection offered by the driver and front passenger seat belts.

the driver air bag (inflator) module is deployed from the center of the steering column

the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger seat

AIR BAG SYSTEM 10B-3
GENERAL DESCRIPTION
With the air bag system which includes air bags for both the driver's
and passenger's sides as well as the seat belt pretensioners (if
equipped), the sag of the seat belt is taken up, the driver air bag (in-
flator) module is deployed from the center of the steering column
and the passenger air bag (inflator) module from the top of the
instrument panel in front of the front passenger seat in occurrence
of a front collision with an impact larger than a certain set value to
supplement protection offered by the driver and front passenger
seat belts.
The air bag system is designed to activate only in severe frontal col-
lisions. It is not designed to activate in rear impacts, side impacts,
rollovers, or minor frontal collisions, since it would offer no protec-
tion in those types of accidents.
