Catalytic Converter
54G236
The purpose of the catalytic converter is to
minimize the amount of harmful pollutants
in your vehicle’s exhaust. Use of leaded
fuel in vehicles equipped with catalytic
converters is prohibited by federal law,
because lead deactivates the pollutant-
reducing components of the catalyst sys-
tem.
The converter is designed to last the life of
the vehicle under normal usage and when
unleaded fuel is used. No special mainte-
nance is required on the converter. How-
ever, it is very important to keep the engine
properly tuned. Engine misfiring, which
can result from an improperly tuned
engine, may cause overheating of the cat-
alyst. This may result in permanent heat
damage to the catalyst and other vehicle
components.
54G584S
CAUTION
To minimize the possibility of catalyst
or other vehicle damage:
 Maintain the engine in the proper
operating condition.
 In the event of an engine malfunc-
tion, particularly one involving
engine misfire or other apparent
loss of performance, have the vehi-
cle serviced promptly.
 Do not shut off the engine or inter-
rupt the ignition when the transaxle
is in gear and the vehicle is in
motion.
 Do not try to start the engine by
pushing or towing the vehicle or
coasting down a hill.
 Do not idle the engine with any
spark plug wires disconnected or
removed, such as during diagnos-
tic testing.
 Do not idle the vehicle for pro-
longed periods if idling seems
rough or there are other malfunc-
tions.
 Do not allow the fuel tank to get
near the empty level.
WARNING
Be careful where you park and drive;
the catalytic converter and other
exhaust components can get very
hot. As with any vehicle, do not park
or operate this vehicle in areas where
combustible materials such as dry
grass or leaves can come in contact
with a hot exhaust system.

The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform recom-
mended maintenance items enclosed with a rectangle will not nullify the emission warranty or limit recall liability prior to the completion
of the vehicle’s useful life. SUZUKI, however, urges that all recommended maintenance services be performed at the indicated inter-
vals and the maintenance recorded.
Periodic Maintenance Schedule: 1, 2, 3, 4, 5, 6, 9, 10

9-7INSPECTION AND MAINTENANCE

Changing OilSince special procedures, materials and
tools are required to change the automatic
transaxle oil, it is recommended that you
trust this job to your authorized SUZUKI
dealer.
Engine Coolant
56KN049
60A208
Selection of CoolantTo maintain optimum performance and
durability of your engine, use SUZUKI
Genuine Coolant or equivalent.
This type of coolant is best for your cooling
system as it:
 Helps maintain proper engine tempera-
ture.
 Gives proper protection against freezing
and boiling.
 Gives proper protection against corro-
sion and rust.
Failure to use the proper coolant can dam-
age your cooling system. Your authorized
SUZUKI dealer can help you select the
proper coolant.
CAUTION
After checking or adding oil, be sure
to insert the dipstick securely.
EXAMPLE
FULL
LOW
CAUTION
To avoid damaging your cooling sys-
tem:
 Always use a high quality ethylene
glycol base phosphate type coolant
diluted with distilled water at the
correct mixture concentration.
 Make sure that the proper mix is 50/
50 coolant to distilled water and in
no case higher than 70/30. Concen-
trations greater than 70/30 coolant
to distilled water will cause over-
heating conditions.
 Do not use straight coolant nor
plain water.

INSPECTION AND MAINTENANCE
80J21-03E
Spark Plugs
65D180
You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.
To access the spark plugs,
1) disconnect the coupler while pushing
the release lever,
2) remove the bolt, and
3) pull the ignition coil out.
80G093
EXAMPLE
CAUTION
 When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
 When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads. Tighten
with a torque wrench to 25 Nm (2.5
kg-m, 18.0 lb-ft). Do not allow con-
taminants to enter the engine
through the spark plug holes when
the plugs are removed.
 Never use spark plugs with the
wrong thread size.
CAUTION
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
brand of spark plug other than the
specified plugs, consult your SUZUKI
dealer.
