to raise the level from 0 (0 mm) to 1/8 inch
(3.2 mm) below the filler plug hole.

the bottom of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See Recommended Fluids and
Lubricants on page 7‑11.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps can be affected and adjustment can
be necessary.
If oncoming vehicles flash their high beams at you, this
can mean the vertical aim of your headlamps needs to
be adjusted.
