REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
(a) Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
(b) During disassembly, keep parts in the appropriate order to facilitate reassembly.
(c) Installation and removal of battery terminal: (1) Before performing electrical work, disconnect the
negative (−) terminal cable from the battery.
(2) If it is necessary to disconnect the battery for in- spection or repair, first disconnect the negative ( −)
terminal cable.
(3) When disconnecting the terminal cable, to prevent damage to battery terminal, loosen the cable nut
and raise the cable straight up without twisting or
prying it.
(4) Clean the battery terminals and cable ends with a clean shop rag. Do not scrape them with a file or oth-
er abrasive objects.
(5) Install the cable ends to the battery terminals after loosening the nut, and tighten the nut after installa-
tion. Do not use a hammer to tap the cable ends
onto the terminals.
(6) Be sure the cover for the positive (+) terminal is properly in place.
(d) Check hose and wiring connectors to make sure that they
are connected securely and correctly.
(e) Non−reusable parts (1) Always replace cotter pins, gaskets, O−rings, oilseals, etc. with new ones.
(2) Non−reusable parts are indicated in the component illustrations by the ” ” symbol.
(f) Precoated parts Precoated parts are bolts, nuts, etc. that are coated with
a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened orcaused to move in any way, it must be recoated with
the specified adhesive.
(2) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then apply
the specified seal lock adhesive to the bolt, nut or
threads.

6. FOR VEHICLES WITH AN AUDIO SYSTEM WITH
BUILT−IN ANTI−THEFT SYSTEM
Audio System displaying the sign ANTI −THEFT SYSTEM
shown on the left has a built −in anti −theft system which makes
the audio system soundless if stolen.
If the power source for the audio system is cut even once, the
anti0theft system operates so that even if the power source is
reconnected, the audio system will not produce any sound un-
less the ID number selected by the customer is input again. Ac-
cordingly, when performing repairs on vehicles equipped with
this system, before disconnecting the battery terminals or re-
moving the audio system the customer should be asked for the
ID number afterwards, or else a request made to the customer
to input the ID number. For the method to input the ID number
or cancel the anti−theft system, refer to the Owner’s Manual.
