2001 SUZUKI GRAND VITARA Owners Manual

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”.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
procedures are not followed, parts or system damage could result.

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.

INSPECTION ON VEHICLE
Seat belts with ALR
As to seat belts with ALR (other than driver side seat belt), check them as follows in addition to above check.
•With vehicle at stop, pull seat belt all the way out, let it retract a little and try to pull it. It should not be pulled
out, that is, it should be locked where retracted.
•Let seat belt retract to its original state. Next, pull it half way out, let it retract a little and try to pull it again. It
should be pulled out smoothly, that is it should not be locked at this time.
WARNING:
Never attempt to disassemble or repair the seat belt pretensioner (retractor assembly). If any abnor-
mality is found, be sure to replace it with new one as an assembly.
Be sure to read “SERVICE PRECAUTIONS”, before starting to work and observe every precaution
during work. Neglecting them may result in personal injury or unactivation of the seat belt preten-
sioner, if necessary.

INSPECTION
Seat belts and attaching parts can affect the vital components and systems of a vehicle. Therefore, they should
be inspected carefully and replaced with genuine parts only.
Seat belt
•The seat belt webbing or strap should be free from damage.
•Fully extend the seat belt to make sure there are no twists or tears in it.
Retractor assembly
1) Let the seat belt retract fully to confirm its easy retraction.
•The retractor assembly should lock webbing when pulled quickly.
•The retractor assembly should lock webbing even when tilted (approx. 15°) toward the fore and aft or right
and left directions.
2) Check retractor assembly with seat belt pretensioner appearance visually for following symptoms and if any
one of them is applicable, replace it with a new one as an assembly.
•Pretensioner has activated.
•There is a crack in seat belt pretensioner (retractor assembly).
•Wire harness or connector is damage.
•Seat belt pretensioner (retractor assembly) is damaged or a strong impact (e.g., dropping) was applied to it.
Anchor bolt
•Inspect all seat belt anchor bolts to verify that they are secure.
•All anchor bolts should be secure and torqued to specification.
Belt latch
•Belt latch should be secure when latched.
•Inspect the seat belt buckle, ensuring that it locks and unlocks easily.
•After buckling the seat belt, tug sharply on the belt, checking that the buckle remains locked.WARNING:
Never measure resistance of pretensioner or disassem-
ble it. Otherwise, personal injury may result.
CAUTION:
If seat belt pretensioner (retractor assembly) was
dropped from a height of 30 cm (1 ft) or more, it should
be replaced.
