TOWING
Proper towing equipment is necessary to prevent damage to
the vehicle.
Y
Laws and regulations applicable to vehicles in tow must al-
ways be observed.
As a general rule, towed vehicles should be pulled with the
driving wheels off the ground. If excessive damage or other
conditions prevent towing the vehicle with the driving wheels
off the ground, use wheel dollies.
With either automatic or manual transaxle:
1. Set the ignition switch in the ACC position;
2. Place the selector lever or shift lever in N (Neutral);
3. Release the parking brake.
Caution
l Do not tow the vehicle backward with driving wheels
on the ground. This may cause internal damage to
the transaxles.
l Do not use the hook loops under the front and rear
of the vehicle for towing purposes. These hook
loops are designed ONLY for transport tie-down. If
tie-down hook loops are used for towing, the
front/rear bumper will be damaged.

INSTALLATION OF MOBILE TWO-WAY RADIO SYSTEM
If a mobile two-way radio system is installed improperly or if a high-powered type is used, the EGI system
and other systems may be affected.
When the vehicle is to be equipped with a mobile two-way radio, observe the following precautions:
1. Install the antenna at the farthest point from control units.
2. Install the antenna feeder as far as possible from the control unit harnesses (at least 30 cm [11.8 in]).
3. Ensure that the antenna and feeder are properly adjusted.
4. Do not install a high-powered mobile two-way radio system.

REMOVAL OF IGNITION KEY ON AUTOMATIC
TRANSAXLE MODEL
The selector lever must be in P (PARK) to turn the ignition key
to the OFF position. If the switch seems to be off but the key
cannot be removed, the switch may still be in the ACC posi-
tion, or the selector lever may not be in P (PARK). Shift the
selector lever to P (PARK), and turn the ignition key to the
LOCK position. The key should now be free for removal.

Test Light
The test light, as shown in the figure, uses a 12V bulb. The
two lead wires should be connected to probes.
The test light is used for simple voltage checks and for check-
ing for short circuits.
Caution
l When checking the control unit, never use a bulb
over 3.4W.

Jumper Wire
The jumper wire is used for testing by shorting across switch
terminals and ground connections.
Caution
l Do not connect a jumper wire from the power source
line to a body ground; this may cause burning or
other damage to harnesses or electronic com-
ponents.
Voltmeter
The DC voltmeter is used to measure of circuit voltage. A volt-
meter with a range of 15V or more is used by connecting the
positive (-t-) probe (red lead wire) to the point where voltage
is to be measured and the negative (-) probe (black lead
wire) to a body ground.
-,’
Diagnosis Connector
Insert the probe into the service hole when connecting a jum-
per wire to the diagnosis connector.
Caution
. Do not insert the jumper wire probe into the diag-
nosis connector terminal, which may damage the
terminal.
Ohmmeter
The ohmmeter is used to measure the resistance between two
points in a circuit and also to check for continuity and diagno-
sis of short circuits.
Caution
l Do not attempt to connect the ohmmeter to any cir-
cuit to which voltage is applied; this may burn or
otherwise damage the ohmmeter.

Connectors can be removed by pressing or pulling the lock
lever as shown.
Locking of connector
When locking connectors, make sure to listen for a click that
will indicate they are securely locked.

1. When a tester is used to check for continuity or to measure
voltage, insert the tester probe from the wire harness side.

2. Check the terminals of waterproof connectors from the con-
nector side, as they cannot be accessed from the wire har-
ness side.
Caution
l Use fine wire to prevent damage to the terminal.
l Do not damage the terminal when inserting the
tester lead.

Inspection
Pull lightly on individual wires to check that they are secured
in the terminal.
Replacement of terminals
Use the appropriate tools to remove the terminal as shown.
When installing the terminal, be sure to insert it until it locks
securely.
< Female >
Insert a thin piece of metal from the terminal side of the con-
nectar, and then, with the terminal locking tab pressed down,
pull the terminal out from the connector.
< Male >
Sensors, Switches, and Relays
Handle sensors, switches, and relays carefully. Do not drop
them or strike them against other parts.
