0B-8 MAINTENANCE AND LUBRICATION
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 or SJ
grade.
NOTE:
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 3 minutes. Stop it and wait 5 min-
utes before checking oil level. Add oil, as necessary, to bring
oil level to FULL level mark on dipstick.
[A]: Proper engine oil viscosity chart
H27 engine
Oil pan capacity liters (US/lmp pt.) About 5.0 (10.6/8.8)
Oil filter capacity liters (US/lmp pt.) About 0.5 (1.1/0.9)
Others liters (US/lmp pt.) About 0.7 (1.5/1.2)
Total liters (US/lmp pt.) About 6.2 (13.1/10.9)
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.)

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).
CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using refrigerant CFC-12 (R-12) and the other using refrigerant HFC-134a (R-134a).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to “REFRIGERANT TYPE” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
 For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in FOREWORD of this manual.
 For basic servicing method of the air conditioning system that is not described in this section, refer
to “AIR CONDITIONING BASIC MANUAL (99520-02130)”.

6F2-6 IGNITION SYSTEM (FOR H27 ENGINE)
Ignition Spark Check
1) Remove surge tank cover.
2) Disconnect injector coupler (1).
3) Remove spark plug and check it for condition and type, refer-
ring to “SPARK PLUG” in this section.
4) If OK, connect ignition coil coupler to ignition coil assembly
and connect spark plug to ignition coil assembly. Ground
spark plug.
5) Crank engine and check if each spark plug sparks.
If no spark is emitted, inspect the related parts as described
under “DIAGNOSIS” in this section.
6) After checking, install spark plug, referring to “SPARK PLUG”
in this section.
7) Connect injector coupler (1).
8) Install surge tank cover.
Ignition Timing Check and Adjustment
1) Start engine and warm it up to normal operating tempera-
ture.
2) Make sure that all of electrical loads except ignition are
switched off.
3) Check to be sure that idle speed is within specification.
Refer to Section 6E2.
4) Connect SUZUKI scan tool to DLC (1) with ignition switch
OFF, restart engine and fix ignition timing by using fixed
spark mode of SUZUKI scan tool.
Special tool
(A) : SUZUKI scan tool WARNING:
Without disconnection of injector coupler, combustible
gas may come out from spark plug holes during this test
and may get ignited in engine room.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
model), and set parking brake.

7B1-44 AUTOMATIC TRANSMISSION (4 A/T)
LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature (20 – 30 °C (68 – 86
°F)) performed after repair or fluid change before test driving is
just preparation for level check of normal operating temperature.
The checking procedure itself is the same as that described previ-
ously. If the fluid level is between FULL COLD and LOW COLD,
proceed to test drive. And when the fluid temperature has
reached the normal operating temperature, check fluid level again
and adjust it as necessary.
Fluid change
1) Lift up vehicle.
2) With engine is cool, remove drain plug (1) from oil pan and
drain A/T fluid.
3) Install drain plug (1).
Tightening torque
A/T fluid drain plug (a) :
23 N·m (2.3 kg-m, 17.0 lb-ft)
4) Lower vehicle and fill proper amount of an equivalent of
DEXRON
®-III.
5) Check fluid level referring to “LEVEL CHECK NORMAL
OPERATING TEMPERATURE” of “FLUID LEVEL” in this
section.
Fluid specification :
An equivalent of DEXRON
®-III
Fluid capacity
When draining from drain plug hole:
2.5 liters (5.28/4.40 US/lmp.pt.)
When overhauling:
6.8 liters (14.37/11.97 US/lmp.pt.)

module, and be sure to lock connector with lock lever.
a) Connect connector.
b) Lock connector with lock lever.
4) Install glove box.
5) Install “AIR BAG” fuse to “AIR BAG” fuse box.

NOSTIC SYSTEM CHECK” in this section.
Handling and storage
SDM
•Never attempt disassembly of SDM.
•When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
•If SDM has been dropped, replace it with a new one.
•If installation part of SDM was damaged, repair that part
completely before reinstallation.
•All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
WARNING:
Never power up air bag system when SDM is not rigidly
attached to the vehicle. Otherwise, personal injury may
result.
CAUTION:
After detecting one time of such collision as to meet
deployment conditions, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.

10B-56 AIR BAG SYSTEM
Repairs and Inspections Required after an Accident
Accident with deployment/activation - component replacement
Certain air bag system components must be replaced. Those components are:
•Driver and passenger air bag (inflator) modules
–Replace with new one.
•Driver and Passenger seat belt pretensioners
–Replace with new one.
•SDM after detecting such collision as to meet deployment conditions
–Replace with new one.
•Forward sensors
–Replace with new one. CAUTION:
All air bag system components, including the electrical harness (component mounting points),
must be inspected after an accident. If any components are damaged or bent, they must be replaced
even if air bag system activation did not occur.
Never use air bag system parts from another vehicle.
Do not attempt to service the parts below. Service of these parts is by replacement only.
–Driver/Passenger air bag (inflator) modules, Driver/Passenger seat belt pretensioners
–Forward sensors
–SDM
–Contact coil and combination switch assembly
–Air bag wire harness
Proper operation of the sensors and air bag system requires that any repairs to the vehicle struc-
ture return it to its original production configuration.
CAUTION:
After detecting one time of such collision as to meet deployment conditions, the SDM must not be
used.
Refer to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when checking the SDM.
