pg. 11 Warning lights
The warning lights described on this page should never be on when drivin\
g

When the ignition is turned on, and before the engine starts, all of the\
warning lights should be on to test
the function of the bulbs. Should a light not go off after the engine ha\
s started, the system indicated
should be inspected. (However, the parking brake reminder light will no\
t go off until the parking brake
is fully released.)

Alternator warning light (red)

If the light comes on while the engine is running,
check the tension of the alternator drive belt as soon
as possible. (See section titled "Cooling system".)
NOTE: This warning light is illuminated if the
alternator is not charging. However, alternator,
parking brake, brake failure, and bulb failure will
be illuminated at the same time due to the design
of the system
Parking brake reminder light (red)

This light will be on when the parking brake
(hand brake) is applied. The parking brake lever
is situated between the front seats. Canadian
models are equipped with this warning light:

Bulb failure warning light (yellow)

The light will come on if any of the following bulbs
are defective:
one of the lower beams
one of the tail lights
one of the brake lights (when the brake pedal is
depressed).
See section on "Replacing Bulbs."
Oil pressure warning light (red)

If the light comes on during driving, the oil
pressure is too low. Stop the engine immediately
and check the engine oil level. See section titled
"Engine Oil". Do not continue to drive the car
with this light on.
After hard driving, the light will come on
occasionally when the engine is idling. This is
normal, provided it goes off when the engine
speed is increased.

Precautionary steps to observe when towing

Please check with state and local authorities before attempting this typ\
e of towing as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
l Steering must be unlocked.
l Remember that power brake and power steering assists will not be availab\
le when engine is
inoperative. Pedal pressure required is 3 - 4 times above normal and gre\
ater steering effort must be
employed.
l Towing cars equipped with automatic transmission:
-- Gear selector in position N. Check transmission oil level (see secti\
on titled "Transmission oil").
-- Maximum speed: 20 mph (30 km/h).
-- Maximum distance with rear wheels on ground: 20 miles (30 km).

CAUTION!
Do not attempt to start the car by pushing or pulling as damage to catal\
ytic converter can
result.

Jump starting, see section titled "alternator, jump starting".
NOTE:
Refer lo the section regarding "On-
Call"
pg. 49 Tow-truck information
Only use wheel lift or flat bed equipment.
CAUTION:
Sling-type equipment applied at the font will damage radiator and air co\
nditioning lines. It is equally
important not to use sling-type equipment at the rear or apply lifting e\
quipment inside the rear wheels;
serious damage to the rear axle may result.

Check all cooling system hoses and connections for defects or deteriorat\
ion of hoses and loose clamps or
fittings.



Drive belts

The belt tension can be checked by depressing the fan belt at a point mi\
dway between the alternator and
fan pulleys as illustrated. It should be possible to press down the belt\
about 1/4" - 3/8" (5-10 mm). This
also applies to other drive belts on the engine.
If drive belts are replaced, recheck belt tension after driving 600 - 1,\
200 miles (1,000 - 2,000 km).

Cooling system

The risk of overheating is greatest, especially in hot weather, when:
- towing a trailer up steep inclines for prolonged periods at full throt\
tle, and at low engine rpm.
- idling for prolonged periods while the air conditioning system is in o\
peration.
- stopping the engine suddenly after high speed driving, so called after\
-boiling.
To avoid overheating. the following rules should be followed.
l Reduce speed and downshift when towing a trailer up long steep inclines.\
The risk of over heating can
be reduced by switching off the air conditioning system for a short whil\
e.
l Do not let the engine idle unnecessarily.
l Do not stop the engine immediately after high-speed driving, but allow t\
he engine to idle for 1/2 - 1
minute before switching off.
When the risk of overheating is imminent, or in the event of overheating\
, (the temperature gauge goes
repeatedly into, or stays continually in, the red section) the followin\
g precautions should be taken:
l Switch off the air conditioning system and switch the heater to full (m\
aximum) position.
l Stop the car and put the gear lever into neutral position-position N. Do\
not stop the engine!
l Increase the engine speed to approx. 2000 rpm (twice idling speed).
l Check the level of coolant in the expansion tank. Top-up, if necessary

Electrical System cautions

When changing the battery or when carrying out work involving the electr\
ical system, the following
should be observed:

1 A battery connection to the wrong terminal will damage the diodes. Bef\
ore connections are made,
check the polarity of the battery with a voltmeter.

2 If booster batteries are used for starting, they must be properly conn\
ected to prevent the diodes from
being damaged. For correct connection, see "Jump starting".

3 The battery leads should be disconnected any time the battery is being\
charged.

4 Never disconnect the battery circuit (for example, to change the batt\
ery) while the engine is running,
as this will immediately ruin the alternator. Always make sure that all \
the battery connections are
cleaned and properly tightened.

5 If any electrical welding work is performed on the vehicle, the ground\
lead and all the connecting
cables of the alternator must be disconnected and the welder wires place\
d as near the welding point as
possible.



Jump starting
CAUTION: Improper hook-up of jumper cables or the use of other than 12 v\
olt batteries could result
in damage to equipment and/or battery.

Check that cars are not touching to prevent premature completion of nega\
tive circuit.
Note the position of the battery terminals. When using jumper cables, fi\
rst connect booster battery
positive (+) terminal to car battery positive (+) terminal. Then con\
nect booster battery negative (-)
terminal to a stationary solid metal part on the engine at a point away \
from the battery. Do not connect
booster cable to any part of fuel system or any moving parts. Avoid touc\
hing hot manifolds.
