Downloaded from www.Manualslib.com manuals search engine Be sure to use the
correct fuse.
Spare fuses are provided, however if you ever have a problem on the road
and don’t have a spare fuse, you
can “borrow” one of the correct value. Just
pick some feature of your vehicle that you can get along without-like the
radio or cigarette lighter-and use its fuse, if it is of the value you need.
Replace it as soon as you
can. See “Fuses and Circuit Breakers” in this
section.
To reinstall the fuse panel cover, push in and turn the fastener clockwise.

3- The California Air Resources Board has determined that the failure to
perform this maintenance item will
not nullify the emission warranty or
limit recall liability prior to the completion of vehicle useful life. We,
however, urge that all recommended maintenance services be perfo\
rmed at
the indicated intervals and the maintenance be recorded.
** Drive axle service:
0 Locking Differential - Drain fluid and refill at first engine oil change.
At subsequent oil changes, check fluid level and add fluid as needed. If
driving
in dusty areas or towing a trailer, drain fluid and refill every
15,000 miles
(25 000 km).
Standard Differential - Check fluid level and add fluid as needed at
every oil change. If driving in dusty areas or towing a trailer, drain
fluid and refill every
15,000 miles (25 000 km).
More frequent lubrication may be required for heavy-duty or off-road
use.
