Buick 2009 Enclave - Manual (Page 305)

All-Wheel Drive
It is recommended that the all-wheel
drive lubricants be checked and
filled by the dealer/retailer.
When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check
the lubricant. See Scheduled
Maintenance on page 6-3.
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.
Bulb Replacement
For the proper type of replacement
bulbs, see Replacement Bulbs
on page 5-35.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
