FLOOR PAN INSPECTIONM42FIADA common result of body leaks is a soaked floor mat pad or
carpet, and it’s not unusual to find that the water is getting in
through the floor pan to some other low point
jn the body. It is
possible however, for water to enter higher up and run
downward to soak the mat.
Since a soaked mat should be removed for drying, it’s a good
way to start your check. Of course, mat removal means you’ll
have to take off door sill plates and pull out seats or seat
cushion. But, this gives you a clear field for action so you can
check body seam sealing and the plugs in the floor pan.
It’s usually not practical to water test for floor pan or
wheelhousing leaks unless a special underbody water spray
arrangement is available. As an alternate, the best way to
locate these leak points is to look for rusty seam edges or other
traces of leaks after the mats and cushions are removed.
Traces of mud are an indication that the water is coming in from
below.

52B-2SUPPLEMENTAL RESTRAINT SYSTEM (SRS) - General informationGENERAL INFORMATION
INTRODUCTIONThe Supplemental Restraint System (SRS) is de-
signed to supplement the driver’s seat belt to help
reduce the risk or severity of injury to the driver by
activating and deploying a driver’s-side air bag in
certain frontal collisions.
The SRS consists of: left front and right front impact
sensors located, one each, on the right and left front
upper frame lowers; an air bag module located in
the center of the steering wheel, which contains the
folded air bag and an inflator unit; the SRS diagnosis
unit located under the rear console assembly, which
monitors the system, and which contains a safing
impact sensor; an SRS warning light located on the
instrument panel, which indicates the operational
status of the SRS; a clock spring interconnection
located within the steering column; system wiring
and wiring connectors; and a knee bolster located
SRS warning light
M52BAAFunder the steering column.
The SRS is designed so that the air bag will deploy
when the safing sensor, plus either or both of the
left front and right front impact sensors simul-
taneously activate while the ignition switches
“ON”.
That is designed to occur in frontal or near-frontal
impacts of moderate to severe force.
Only authorized service personnel should do work
on or around the SRS components. Those service
personnel should read this manual carefully before
starting any such work. Extreme care must be used
whenservicing the SRS, to avoid injury to the
service personnel (by inadvertent deployment of the
air bag) or the driver (by rendering the SRS inopera-
tive).
SELF-DIAGNOSIS/SRS WARNING LIGHT FUNCTION
The diagnosis unit monitors the SRS system and stores data
concerning any detected faults in the system. When the
ignition key is in “ON” or “START” position, the SRS warning
light should illuminate for about 7 seconds and then turn off.
That indicates that the SRS system is in operational order. If the
SRS warning light does any of the following, immediate
inspection by an authorized dealer is needed.
(1) The SRS warning light does not illuminate as described
above.
(2) The SRS warning light stays on for more than 7 seconds.
(3) The SRS warning light illuminates while driving.
If a vehicle’s SRS warning light is in any of these three
conditions when brought in for inspection, the SRS system
must be inspected, diagnosed and serviced
In accordance wrth
this manual.

iiCAUTION: SRS diagnosis unit
This unit cannot be repaired.
If defective, remove and replace entire unit per
service manual instructions.
Do not disassemble or tamper.
See service manual for handling and storage
instructions.Driver’s air bag information
This vehicle
ha% an air bag which will supple-
ment the driver’s seatbelt in certain frontal
collisions. The air bag is not a substitute for the
driver’s seatbelt in any type of collision. The
driver, and all other occupants, should wear
seatbelts at all times.
WARNING!
If the “SRS” warning light does not come.on
for about 7 seconds when ignition key is turned
to “ON” or engine is started, or if it stays on
while driving, drive the vehicle to your nearest
authorized dealer right away. Also do so if
vehicle’s front end is damaged or if air bag has
deployed.
The air bag system must be inspected by an
authorized dealer ten years after vehicle manu-
facture date shown on certification label lo-
cated on left front door-latch post or door
frame.Read “SRS” section of your owner’s manual
before driving, for important information, about
Dperation, service and disposal of the air bag
svstem.
Do no drop: keep dry.
Failure to follow instructions could render air
bag inoperative and result in driver injury.
F. CAUTION: SRS
Before replacing steering wheel, read service
manual, center front wheels
ahd align SRS
clock spring neutral marks.
Failure to do so may render SRS system
inoperative, risking serious driver injury.
