NOTE:
When cleaning rear window glass, use a dry cloth to
wipe it along heat wire (1) direction.
When cleaning glass, do not use detergent or abra-
sive-containing glass cleaner.
When measuring wire voltage, use a tester with nega-
tive probe (2) wrapped with a tin foil (3) which should
be held down on wire by finger pressure.

Wire damage inspection.
a) Turn ignition switch ON.
b) Turn defogger switch ON.
c) Check voltage at the center (1) of each heat wire as shown
below.
If measured voltage is 10 V, wire must be damaged
between its center and positive end (5).
If voltage is 0 V, wire must be damaged between its center
and ground end (6).
Damage point locating.
a) Turn ignition switch ON.
b) Turn defogger switch ON.
c) Touch voltmeter positive (+) lead to heat wire positive ter-
minal end (1).
d) Touch voltmeter negative (-) lead with a foil strip to heat
wire positive terminal end (1), then move it along wire to the
negative terminal end (2).
e) The place where voltmeter fluctuates from 0 - 2 V (3) to
several volts (4) is where there is damage.
REPAIR
1) Use white gasoline for cleaning.
2) Apply masking tape (1) at both upper and lower sides of heat
wire (2) to be repaired.
3) Apply commercially-available repair agent (3) with a fine-tip
brush (4).
4) 2 to 3 minutes later, remove masking tapes (1).
5) Leave repaired heat wire as it is for at least 24 hours before
operating rear defogger again.Voltage Criteria

HOW TO REGISTER IGNITION KEY ........... 8G-23 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).
