In addition to standard maintenance
items, vehicles that are driven under
special operating conditions require
further maintenance service. These
special operating conditions, which
put added demands on a vehicle,
include:
•
Driving off-road, on dirt roads or
on dusty roads
•
Towing a trailer, using a car-top
carrier or heavy vehicle loading
•
Repeated trips of less than five
miles in temperatures below
32° F or 0°C
•
Extensive idling and/or low-
speed driving for long distances,
such as police, taxi or door-to-
door delivery use
If you drive primarily under any
of the conditions noted above,
you should replace the engine
oil and oil filter every six months
or 5,000 miles. Some of these
special operating conditions
require other maintenance items;
these items are indicated in each
maintenance chart.
SPECIAL OPERATING CONDITIONS
Note: If you drive only occasionally
under any of the special operating
conditions noted, it is not necessary
to change the oil every six months or
5,000 miles or to perform the addi-
tional services listed in the charts. This
added maintenance is required only if
you drive primarily under any of the
special operating conditions.
