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).
NOTE:
Whether following systems (parts) are used in the particular vehicle or not depends on specifications.
Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor (s) or CO adjusting resistor
Three way catalytic converter (TWC) and warm up three-way catalytic converter (WU-TWC)

Exhaust Manifold .......................................... 6K-2
Exhaust Pipe ................................................. 6K-2

General Description
The exhaust system of this vehicle consists of the exhaust manifold, exhaust center pipe, muffler, seals, etc.
The catalytic converter is an emission control device added to the exhaust system to lower the level of Hydro-
carbon (HC), Carbon Monoxide (CO) and Oxides of Nitrogen (NOx) pollutants in the exhaust gas. The catalyst
in the catalytic converter is of “Three way” type.
Maintenance
At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust
system as follows:
Check rubber mountings for damage, deterioration and out of position.
Check exhaust system for leakage, loose connection, dent and damage.
If bolts or nuts are loosened, tighten them to specified torque. Refer to “Components” in this section.
Check nearby body areas for damaged, missing, or mispositioned part, open seam, hole, loose connection
or any other defect which could permit exhaust fumes to seep into vehicle.
Make sure that exhaust system components have enough clearance from underbody to avoid overheating
and possible damage to passenger compartment carpet.
Any defect should be fixed at once. NOTE:
Whether following parts are used in the particular vehicle or not depends on specification. Be sure to
bear this in mind when performing service work.
Three-Way Catalytic Converter (TWC)
CAUTION:
Be sure to use UNLEADED FUEL for the catalytic converter equipped vehicle. Use of LEADED FUEL
will affect performance of the catalytic converter adversely to a great extent.
WARNING:
To avoid danger of being burned, do not touch exhaust system when system is hot.
Any service on exhaust system should be performed when system is cool.
