3. Differential Gear Oil
A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the differential oil level gauge and wipe
it clean.
3) Reinsert the level gauge all the way. Make sure
the level gauge is inserted correctly and in the
proper orientation.
4) Remove the oil level gauge again, and check the
level of differential gear oil. If the differential gear oil
level is below “L” line, add oil to bring the level up to
“F” line.
NOTE:
To prevent overfilling the differential gear oil, do not
fill oil above the “F” line.
B: REPLACEMENT
1) Lift up the vehicle.
2) Remove the differential gear oil drain plug using
TORX
®
bit T70, and drain the differential gear oil
completely.
CAUTION:
• Immediately after driving the vehicle or after
idling for a long time, the differential gear oil
will be hot. Be careful not to receive burns.
• Be careful not to spill differential gear oil on
the exhaust pipe to prevent it from emitting
smoke or causing a fire. If differential gear oil is
spilled on the exhaust pipe, wipe it off com-
pletely.
3) Replace the gasket with a new part and tighten
the differential gear oil drain plug using the TORX
®
bit T70.
