WARNING: This page is about a different car, the 2004 Suzuki XL-7 and 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Hypoid gear oil must be used for differential.
It is highly recommended to use SAE 80W-90 viscosity.

Before oil change or inspection, be sure to stop engine and lift up vehicle horizontally.
Check oil level and existence of leakage. If leakage is found, correct its cause.
Drain old oil and pour proper amount of gear oil as specified below (roughly up to level hole).
