WARNING/CAUTION/NOTE
Please read this manual and follow its instructions carefully. To emphasize special information, the words
WARNING, CAUTION and NOTE have special meanings. Pay special attention to the messages highlighted by
these signal words.
WARNING:
Indicates a potential hazard that could result in death or injury.
CAUTION:
Indicates a potential hazard that could result in vehicle damage.
NOTE:
Indicates special information to make maintenance easier or instructions clearer.
WARNING:
This service manual is intended for authorized Suzuki dealers and qualified service mechanics only.
Inexperienced mechanics or mechanics without the proper tools and equipment may not be able to
properly perform the services described in this manual.
Improper repair may result in injury to the mechanic and may render the vehicle unsafe for the driver
and passengers.
WARNING:
For vehicles equipped with a Supplemental Restraint or 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.
• If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.
• Do not modify the steering wheel, instrument panel or any other air bag system component on or
around air bag system components or wiring. Modifications can adversely affect air bag system
performance and lead to injury.
• If the vehicle will be exposed to temperatures over 93°C (200°F), for example, during a paint baking
process, remove the air bag system components, that is air bag or inflator modules, SDM and/or
seat belt with pretensioner, beforehand to avoid component damage or unintended activation.

  • Page 18: Electrical Circuit Inspection Procedure

    GENERAL INFORMATION 0A-13 Electrical Circuit Inspection Procedure While there are various electrical circuit inspection methods, described here is a general method to check its open and short circuit by using an ohmmeter and a voltmeter. Open circuit check Possible causes for the open circuit are as follows. As the cause is in the connector or terminal in many cases, they need to be checked particularly carefully.
  • Page 19 0A-14 GENERAL INFORMATION CONTINUITY CHECK 1) Measure resistance between connector terminals at both ends of the circuit being checked (between A-1 and C-1 in the figure). If no continuity is indicated (infinity or over limit), that means that the circuit is open between terminals A-1 and C-1. 2) Disconnect the connector included in the circuit (connector-B in the figure) and measure resistance between terminals A-1 and B-1.

Generally, the only adjustment required for front wheel alignment is toe setting. Camber and caster can’t be adjusted. Therefore, should camber or caster be out of specification due to the damage caused by hazardous road conditions or collision, whether the damage is in body or in suspension should be determined.
