OIL 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
exists, correct or repair it.
3) Drain old oil, tighten drain plug (3) after applying sealant to
its thread and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
“A” : Sealant 99000-31230
Tightening torque
Transfer oil drain plug (a) : 21 N·m (2.1 kg-m, 15.5 lb-ft)
Transfer gear oil
:Hypoid gear oil API GL-5
For oil viscosity, refer to the chart.
Oil Capacity
: 0.5 liters (1.1/0.9 US/lmp. pt)
4) Torque level/filler plug (4) as specified below after applying
sealant to its thread.
“A” : Sealant 99000-31230
Tightening torque
Transfer oil level / filler plug
(b) : 21 N·m (2.1 kg-m, 15.5 lb-ft) NOTE:
 It is highly recommended to use SAE 80W-90 Hypoid
gear oil API GL-5.
 Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage.

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).
