6) Replenish oil until oil level is brought to FULL level mark on
dipstick. (oil pan and oil filter capacity). The filler inlet is at
the top of the cylinder head cover.
It is recommended to use engine oil of SE, SF, SG, SH, SJ or
SL grade.
Select the appropriate oil viscosity according to the proper
engine oil viscosity chart [A].
Engine oil specification
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for three minutes. Stop it and wait five
minutes before checking oil level. Add oil, as necessary, to
bring oil level to FULL level mark on dipstick.
Engine Coolant
CHANGE
Change engine coolant referring to “Cooling System Flush and
Refill” in Section 6B.
Exhaust System
INSPECTION
Oil pan capacity About 3.8 liters (8.0/6.7 US/lmp pt.)
Oil filter capacity About 0.2 liters (0.4/0.3 US/lmp pt.)
Others About 0.3 liters (0.6/0.5 US/lmp pt.)
Total About 4.3 liters (9.1/7.6 US/lmp pt.)
NOTE:
Engine oil capacity is specified. However, note that the
amount of oil required when actually changing oil may
somewhat differ from the data in the table depending on
various conditions (temperature, viscosity, etc.)
1. Full level mark (hole)
2. Low level mark (hole)
WARNING:
To avoid danger of being burned, do not touch exhaust
system when it is still hot. Any service on exhaust sys-
tem should be performed when it is cool.

CIRCUIT DESCRIPTION
DTC CONFIRMATION PROCEDURE
1) Turn ignition switch OFF. Clear DTC with ignition switch ON, check vehicle and environmental condition for :
–Altitude (barometric pressure) : 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
–Ambient temp. : –10 °C, 14 °F or higher
–Intake air temp. : 70 °C, 158 °F or lower
–Engine coolant temp. : 70 °C, 158 °F or higher
2) Warm up engine to normal operating temperature.
3) Increase vehicle speed to 30 – 40 mph, 50 – 60 km/h in 3rd gear or “D” range and hold throttle valve at that
opening position for 1 min.
4) Stop vehicle.
5) Check DTC in “DTC” mode and pending DTC in “ON BOARD TEST” or “PENDING DTC” mode.
INSPECTION
DTC DETECTING CONDITION POSSIBLE CAUSE
After engine warmed up.
Difference between actual throttle opening (detected from TP sensor)
and opening calculated by ECM (Obtained on the basis of engine
speed and intake manifold pressure) in larger than specified value.
✱2 driving cycle detection logic, continuous monitoringTP sensor malfunction
High resistance in the circuit
ECM malfunction
WARNING:
When performing a road test, select a place where there is no traffic or possibility of a traffic acci-
dent and be very careful during testing to avoid occurrence of an accident.
Road test should be carried out with 2 persons, a driver and a tester, on a level road.
Step Action Yes No
1Was “Engine Diag. Flow Table” performed? Go to Step 2. Go to “Engine Diag. Flow
Table”.
2 Is SUZUKI scan tool available? Go to Step 3. Go to Step 4.
3 Check TP Sensor and Its Circuit.
1) Turn ignition switch OFF and connect
SUZUKI scan tool to DLC. See Fig. 1.
2) Turn ignition switch ON and check TP sen-
sor output voltage when throttle valve is at
idle position and fully opened. See Fig. 3.
Dose voltage vary within specified value linearly
as shown in figure?Substitute a known-good
ECM and recheck.Go to Step 5.

DTC CONFIRMATION PROCEDURE
1) Turn ignition switch OFF.
Clear DTC with ignition switch ON, check vehicle and environmental condition for :
–Altitude (barometric pressure) : 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
–Ambient temp. : –10 °C, 14 °F or higher
–Intake air temp. : 70 °C, 158 °F or lower
–Engine coolant temp. : 70 – 110 °C, 158 – 230 °F
2) Start engine and drive vehicle at 35 – 45 mph, 55 – 65 km/h for 8 min. or longer.
While this driving, if “Catalyst Monitoring TEST COMPLETED” is displayed in “READINESS TESTS” mode
and DTC is not displayed in “DTC” mode, confirmation test is completed.
If “TEST NOT COMPLTD” is still being displayed, continue test driving.
3) Decrease vehicle speed at 30 – 40 mph, 50 – 60 km/h, and hold throttle valve at that opening position for 2
min. and confirm that short term fuel trim vary within – 20% – +20% range.
4) Stop vehicle (do not turn ignition switch OFF) and confirm test results according to following “Test Result
Confirmation Flow Table”. DTC DETECTING CONDITION POSSIBLE CAUSE
While vehicle running at constant speed under other than
high load.
Time from rich or lean switching command is output till HO2S-
2 output voltage crosses 0.45 V less than specified value.

Radiator Cap
A pressure-vent cap is used on the radiator. The cap contains a
pressure valve (1) and ventilation valve (2).
The cap has its face marked 1.1, which means that its pressure
valve opens at 1.1 kg/cm
2 (15.6 psi, 110 kPa).
Coolant Reservoir
A “see-through” plastic reservoir (1) is connected to the radiator
by a hose.
Coolant level should be between “FULL” level mark (2) and
“LOW” level mark (3) on the reservoir.
Coolant should be added only to the reservoir as necessary.NOTE:
Do not remove radiator cap to check engine coolant
level; check coolant visually at the see-through coolant
reservoir.
Coolant should be added only to reservoir as necessary.
WARNING:
As long as there is pressure in the cooling system, the
temperature can be considerably higher than the boiling
temperature of the solution in the radiator without caus-
ing the solution to boil. Removal of the radiator cap while
engine is hot and pressure is high will cause the solution
to boil instantaneously and possibly with explosive force,
spewing the solution over engine, fenders and person
removing cap. If the solution contains flammable anti-
freeze such as alcohol (not recommended for use at any
time), there is also the possibility or causing a serious
fire.
[A]: At air bleed 3. From reservoir
[B]: At valves closed 4. To reservoir
[C]: At pressure relief 5. Pressure in radiator
[D]: At vacuum relief
NOTE:
When installing reservoir cap, set arrow marks (4) on the
reservoir and cap as the figure.
