maintenance TOYOTA SUPRA 1995 Service Repair Manual

4. COMPACT DISC PLAYER
Compact Disc (hereafter called ºCDº) Players use a laser
beam pick±up to read the digital signals recorded on the CD
and reproduce analog signals of the music, etc. There are 4.7
in. (12 cm) and 3.2 in. (8 cm) discs in the CD player.
HINT: Never attempt to disassemble or oil any part of the
player unit. Do not insert any object other than a disc into the
magazine.
NOTICE: CD players use an invisible laser beam which
could cause hazardous radiation exposure. Be sure to
operate the player correctly as instructed.
MAINTENANCE
Tape Player/Head Cleaning
(a) Raise the cassette door with your finger.
Next using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in cleaner,
clean the head surface, punch rollers and capstans.
CD Player/Disc Cleaning
If the disc gets dirty, clean the disc by wiping the surfaces
from the center to outside in the radial directions with a soft
cloth.
NOTICE: Do not use a conventional record cleaner or anti
±static preservative.

1. CHECK BATTERY ELECTROYTE LEVEL AND VOLTAGE
(a) Check the electrolyte quantity of each cell.
Maintenance±Free Battery:
If under the lower level, replace the battery (or add distilled
water if possible.). Need to check the charging system.
Except Maintenance±Free Battery:
If under the lower level, add distilled water.
(b) Except Maintenance±Free Battery:
Check the specific gravity of each cell.
Standard specific gravity:
1.27±1.29 at 205C (685F)
If the specific gravity is less than specification, charge the
battery.
(c) Maintenance±Free Battery:
Measure the battery voltage between the negative (±) and
positive (+) terminals of the battery.
Standard voltage:
12.7±12.9 V at 205C (685F)
HINT:
wBefore measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight,
blower motor, rear defogger etc.) for 60 seconds to
remove the surface charge.
wIf the vehicle has been running, wait 5 minutes or more
after the vehicle stops before measuring the battery
voltage.
If the voltage is less than specification, charge the battery.
HINT: Check the indicator as shown in the illustration.

MAINTENANCE
GENERAL NOTES:
wThere are two separate maintenance schedules,
namely A and B, which apply to different driving
conditions. Find out how the vehicle is driven, select the
appropriate schedule and service the vehicle
accordingly.
wEvery service item in the periodic maintenance list must
be performed.
wNext to the columns of periods in the schedule,
reference pages have been added for easy access to
service data and procedures necessary for each
operation.
wThe service interval for scheduled maintenance is
determined by the odometer reading or time interval,
whichever comes first, shown in the schedule.
wMaintenance services after the last period should be
performed at the same interval as before unless
otherwise noted.
wSkipping even one item in the list can cause the engine
to run poorly and increase exhaust emissions.
