Rear Drive Module
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. See Scheduled
Maintenance on page 6-4.
How to Check Lubricant
(A) Filler Plug (B) Drain Plug
To get an accurate reading, the vehicle should be on a
level surface.
5-46
If the level is below the bottom of the filler plug hole,
you will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the filler
plug hole. Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See Recommended Fluids
and Lubricants on page 6-11.

Headlamp Aiming

Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers flash their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your
dealer/retailer for service.
