10-2 RESTRAINT SYSTEM
General Description
SEAT BELT WITH ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the
webbing 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.
SEAT BELT WITH PRETENSIONER (IF EQUIPPED)
The seat belt with ELR and a pretensioner has a pretensioner mechanism which operates in linkage with the air
bag in addition to the above described ELR. The pretensioner takes up the sag of the seat belt in occurrence of
a front collision with an impact larger than a certain set value, thereby enhancing restraint performance.
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 col-
lision with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supple-
ment 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
For more information, refer to Section 10B “Air Bag System”.

Service Precautions
Service and diagnosis
Before servicing or replacing seat belts, refer to following precautionary items.
•Seat belts should be normal relative to strap retractor and buckle portions.
•Keep sharp edges and damaging objects away from belts. Avoid bending or damaging any portion of belt
buckle, latch plate and ELR.
•Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)
•When installing a seat belt anchor bolt, start bolt by hand to prevent cross-threading.
•Use only the correct seat belt anchor bolts and screws and tighten to the correct torque value.
•Do not attempt any repairs on retractor mechanisms or retractor covers. Replace defective assemblies with
new replacement parts.
•Keep belts dry and clean at all times.
•If there exist any parts in question, replace such parts.
•Replace belts whose webbing is cut or otherwise damaged.
•Do not put anything into trim panel opening which seat belt webbing passes through.
For Seat Belt with Pretensioner
Refer to “SERVICE AND DIAGNOSIS” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
Disabling air bag system
Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
Enabling air bag system
Refer to “ENABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
Handling and storage
Refer to “HANDLING AND STORAGE” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
Disposal
Refer to “DISPOSAL” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Section 10B. WARNING:
If replacing seat belt is necessary, replace buckle and ELR (or webbing) together as a set. This is for
the reason of ensuring locking of tongue plate with buckle. If these parts are replaced individually,
such a locking condition may become unreliable. For this reason, SUZUKI will supply only the spare
buckle and ELR (or webbing) in a set part.
WARNING:
When performing service on or around air bag system components or air bag system wiring, disable
the air bag system. Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under
“ON-VEHICLE SERVICE” in Section 10B.
Failure to follow procedures could result in possible air bag activation, personal injury or unneeded
air bag system repairs.

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 pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) 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
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.
