GENERAL INFORMATION 0A-3
PRECAUTIONS
PRECAUTION FOR VEHICLES EQUIPPED
WITH A SUPPLEMENTAL RESTRAINT
(AIR BAG) SYSTEM
WARNING:
The configuration of air bag system parts are as shown in
the figure. When it is necessary to service (remove, rein-
stall and inspect) these parts, be sure to follow proce-
dures described in SECTION 10B. Failure to follow proper
procedures could result in possible air bag system activa-
tion, personal injury, damage to parts or air bag system
being unable to activate when necessary.
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, dashboard, or any other
air bag system components. Modifications can adversely
affect air bag system performance and lead to injury.
If the vehicle will be exposed to temperatures over 93C
(200F) (for example, during a paint baking process), re-
move the air bag system components beforehand to avoid
component damage or unintended air bag system activa-
tion.
DIAGNOSIS
When troubleshooting air bag system, be sure to follow
ªDIAGNOSISº in SECTION 10B. Bypassing these proce-
dures may result in extended diagnostic time, incorrect diag-
nosis, and incorrect parts replacement.
Never use electrical test equipment other than that specified
in this manual.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger) and seat belt preten-
tioners (driver and passenger). It is very dangerous as the
electric current from the tester may deploy the air bag or ac-
tivate the pretensioner.

09915-47330 (G16 and J20 engines)
NOTE:
Before fitting new oil filter, be sure to oil its O-ring. Use engine
oil for this purpose.
4) Screw new filter on oil filter stand by hand until the filter O-ring
contacts the mounting surface.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position at which at filter O-ring first contacts
the mounting surface.
5) Tighten the filter 3 / 4 turn from the point of contact with the
mounting surface using an oil filter wrench.

6) Replenish oil until oil level is brought to FULL level mark on dip-
stick. (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 SG, SH or SJ grade.
NOTE:
For temperature between ±20C (±4F) and 30C (86F), it
is highly recommended to use SAE 10W ± 30 oil.

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.).
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for three minutes. Stop it and wait five min-
utes before checking oil level. Add oil, as necessary, to bring oil
level to FULL level mark on dipstick.
NOTE:
Step 1) ± 7) outlined above must be performed with ENGINE
NOT RUNNING. For step 8), be sure to have adequate ven-
tilation while engine is running.
ITEM 1-5
Engine Coolant Change
WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator are still hot. Scalding fluid
and steam can be blown out under pressure if cap is taken
off too soon.
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug to drain coolant.
3) Remove reservoir, which is on the side of radiator, and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, and run engine for
2 or 3 minutes at idle. This drives out any air which may still be
trapped within cooling system. STOP ENGINE. Add coolant as
necessary until coolant level reaches the filler throat of radiator.
Reinstall radiator cap.

ON-VEHICLE SERVICE
WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
DO NOT USE YOUR HAND TO RUB AFFECTED EYE(S).
Instead, use quantities of fresh cold water to splash it over affected area to thus gradually raise its
temperature above the freezing point.
Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated
in the same manner as when skin is frostbitten or frozen.
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
(For identification between these two types, refer to page 1B-2).
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.
PRECAUTION
When servicing air conditioning system, the following rules must be observed.
PIPING
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling nuts
and O-ring.
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.

oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.

Take care not to cause damage to A / C condenser during
service operation, if equipped.

2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60C (122
± 140F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

INSPECTION AND CHANGE
1) Before changing or inspecting oil, be sure to stop engine and lift
vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage ex-
ists, correct or repair it.
3) Drain old oil and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
NOTE:
It is highly recommended to use SAE 75W-90 gear oil.
Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage and
status of breather hoses.
If water or rust is mixed in drained oil, be sure to check
breather hose and boot of transmission and transfer.

LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part by
measuring fluid pressure in fluid pressure line. Line pressure test
requires following conditions.
Automatic fluid is at normal operating temperature (70 to 80C /
158 ± 176F).
Fluid is filled to proper level (between FULL HOT and LOW HOT
on dipstick).
1) Apply parking brake securely and place checks against wheels.
2) Attach oil pressure gauge to fluid pressure check hole in trans-
mission case.
Special Tool
(A): 09925-37810
CAUTION:
After attaching oil pressure gauge, check that not fluid
leakage exists.
3) Depress foot brake fully, run engine at idle and stall and then
check fluid pressure in ªDº or ªRº range.
CAUTION:
Do not continue running engine at stall speed longer than
5 seconds.
