Maintenance and Specifications
Follow the periodic lubrication procedures and regular inspection
intervals as outlined. Have your dealer or service center inspect your
vehicle at least once a year. Remember that regular maintenance and
replacement of worn components will usually prevent serious problems
from developing later.
Making modifications to various parts, components and systems
of the vehicle, such as brake and steering systems can adversely
affect the quality, reliability and operation of your vehicle and could
result in property damage, personal injury or death. Such modifications
must be avoided.
The lubrication intervals present a good opportunity to inspect the
vehicle. It is suggested that the various points listed herein be checked
at the lubrication or other recommended intervals.
Failure to properly perform maintenance and servicing
procedures could result in vehicle damage, personal injury or
death.
If the owner/operator of the vehicle is a skilled technician and intends on
performing the vehicle maintenance and service, he is strongly urged to
purchase a service manual.
Take care when performing any maintenance, system check or
service on your vehicle. Some of the materials may also be
hazardous if used, serviced or handled improperly and could result in
property damage, personal injury or death.
Air conditioning system checks
Have your air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to air conditioning performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for dirt, lint, etc.
Replace the filter if necessary. Vehicles operating in unusually dusty
conditions may require inspecting and replacing the fresh air filter more
often.
Front axle - general service information
Maintaining the front axle alignment to specifications is very important
and should only be performed by a qualified technician. Toe-in
adjustment is particularly important with radial tires.
