Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake discs, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.After off-road driving, completely inspect the underbody
of your vehicle. Check tires, body structure, steering,
suspension and exhaust system for damage. Check
threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
Service Manual. Also check for accumulations of vegeta-
tion or brush that could become a fire hazard, or conceal
damage to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service to prevent excessive
wear.
414 MAINTAINING YOUR VEHICLE

²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

SUGGESTIONS FOR OBTAINING SERVICE FOR
YOUR VEHICLE
Prepare For The Appointment
If you're having warranty work done, be sure to have the
right papers with you. Take your warranty folder. All
work to be performed may not be covered by the
warranty, discuss additional charges with the service
manager. Keep a maintenance log of your vehicle's
service history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle's problems or the
specific work you want done. If you've had an accident,
or work done that is not on your maintenance log, let the
service advisor know.
Be Reasonable With Requests
If you list a number of items, and you must have your
vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.
At many dealers, you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is advisable
to make these arrangements when you call for an ap-
pointment.
