If the level is below the bottom of the filler plug
hole, located on the front axle, you may need
to add some lubricant:
•
When the differential is cold, add enough
lubricant to raise the level from 0 (0 mm)
to 1/8 inch (3.2 mm) below the filler plug hole.
•
When the differential is at operating
temperature (warm), add enough lubricant
to raise the level to 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 584 .
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 an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles flash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.
It is recommended that the vehicle is taken to
your dealer for service if the headlamps need to
be adjusted. It is possible however, to re-aim
the headlamps as described in the following
procedure.
