All-Wheel Drive
It is recommended that the all-wheel
drive lubricants be checked and
lled by the dealer/retailer.
When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check
the lubricant. SeeScheduled
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 ash
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, seeReplacement Bulbs
on page 5-34.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
Halogen Bulbs
{CAUTION
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
