Front Axle; Headlamp Aiming - Hummer 2009 H3 Owner's Manual

Front Axle

It is not necessary to regularly
check front axle fluid unless a leak
is suspected or an unusual noise
is heard. A fluid loss could indicate
a problem.
It is recommended that the front
axle fluid be checked and filled by
your dealer/retailer.

Headlamp Aiming

The vehicle may have a visual
optical headlamp aiming system.
The aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim
may be affected and adjustment
may be necessary.
If oncoming vehicles flash their
high beams at you, this may also
mean the vertical aim needs to
be adjusted.
It is recommended that the vehicle
is taken to your dealer/retailer
for service if the headlamps need to
be re-aimed. It is possible however,
to re-aim the headlamps as
described.
