BENDIX ANTILOCK 4 BRAKE SYSTEM
1993 FRONT WHEEL DRIVE CAR
This manual supplements the 1993 Front-
Wheel-Drive Car Service Manual 81-270-3101,
and contains the service information on the new
Bendix Antilock 4 brake system. The Bendix
Antilock 4 brake system only affects the LeBaron
Landau, Spirit, Acclaim and LeBaron Coupe and
Convertible built at the Newark Assembly Plant
after April 19, 1993. Any of these model vehicles
built at other assembly plants, will continue to
use carryover antilock brake systems for the
remainder of the 1993 model year.
To order the special service tools used and
illustrated, please refer to the instructions on
inside back cover.

TOWING RECOMMENDATIONS
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams
use of a wheel lift or flat bed towing device (Fig. 8) is
recommended. When using a wheel lift towing de-
vice, be sure the unlifted end of disabled vehicle has
at least 100 mm (4 in.) ground clearance. If mini-
mum ground clearance cannot be reached, use a tow-
ing dolly. If a flat bed device is used, the approach
angle should not exceed 15 degrees.
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums or rotors.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to in-
crease the ground clearance at the opposite end of
the vehicle. Install lug nuts on wheel attaching studs
to retain brake drums or rotors.
LOCKED VEHICLE TOWING
When a locked vehicle must be towed with the
front wheels on the ground, use a towing dolly or flat
bed hauler.
FLAT TOWING WITH TOW BAR
² 4-speed automatic transaxle vehicles can be flat
towed at speeds not to exceed 72 km/h (44 mph) for
not more than 160 km (100 miles). The steering col-
umn must be unlocked and gear selector in neutral.
² 3-speed automatic transaxle vehicles can be flat
towed at speeds not to exceed 40 km/h (25 mph) for
not more than 25 km (15 miles). The steering column
must be unlocked and gear selector in neutral.
² Manual transaxle vehicles can be flat towed at any
legal highway speed with no distance restrictions.
The steering column must be unlocked and gear se-
lector in neutral. WARNING: DO NOT ALLOW TOWING ATTACH-
MENT DEVICES TO CONTACT THE FUEL TANK OR
LINES, FUEL LEAK CAN RESULT. DO NOT LIFT OR TOW VEHICLE BY FRONT OR
REAR BUMPER, OR BUMPER ENERGY ABSORBER
UNITS. DO NOT VENTURE UNDER A LIFTED VEHICLE IF
NOT SUPPORTED PROPERLY ON SAFETY
STANDS. DO NOT ALLOW PASSENGERS TO RIDE IN A
TOWED VEHICLE. USE A SAFETY CHAIN THAT IS INDEPENDENT
FROM THE TOWING ATTACHMENT DEVICE.
CAUTION: Do not damage brake lines, exhaust sys-
tem, shock absorbers, sway bars, or any other un-
der vehicle components when attaching towing
device to vehicle. Remove or secure loose or protruding objects
from a damaged vehicle before towing. Refer to state and local rules and regulations be-
fore towing a vehicle. Do not allow weight of towed vehicle to bear on
lower fascia, air dams, or spoilers.
TOWINGÐFRONT WHEEL LIFT
Chrysler Corporation recommends that a vehicle be
towed with the front end lifted, whenever possible.
TOWINGÐREAR WHEEL LIFT
If a front wheel drive vehicle cannot be towed with
the front wheels lifted, the rear wheels can be lifted
provided the following guide lines are observed.
CAUTION: Do not use steering column lock to se-
cure steering wheel during towing operation.
² Unlock steering column and secure steering wheel
in straight ahead position with a clamp device de-
signed for towing.
² Verify that front drive line and steering compo-
nents are in good condition.
² 4-speed automatic transaxle vehicles can be towed
at speeds not to exceed 72 km/h (44 mph) for not
more than 160 km (100 miles). The gear selector
must be in neutral position.
² 3-speed automatic transaxle vehicles can be towed
at speeds not to exceed 40 km/h (25 mph) for not
more than 25 km (15 miles). The gear selector must
be in neutral position.
² 3-speed automatic transaxle vehicles can be towed
at speeds not to exceed 40 km/h (25 mph) for not
more than 25 km (15 miles). The gear selector must
be in neutral position.

Ä LUBRICATION AND MAINTENANCE 0 - 7

CRANKCASE VENTILATION SYSTEM
Engine crankcase pressure and emissions are
vented into combustion chambers through the posi-
tive crankcase ventilation (PCV) system. The PCV
system consists of a crankcase filter (Fig. 6, 7, 8, 9,
or 10), PCV valve (Fig. 12, 13, 14 or 15) and hoses to
complete a vacuum circuit. The PCV system should
have enough volume to overcome crankcase pressure
created by piston backwash. If a PCV system be-
comes plugged, the crankcase pressure will increase
and force engine oil past the piston rings creating oil
consumption. Blockage of PCV system can occur at
the vacuum source coupling, PCV valve, crankcase
filter or a collapsed hose. Chrysler Corporation recommends that a PCV
valve not be cleaned. A new Mopar or equivalent
PCV valve should be installed when servicing is re-
quired. Over a period of time, depending on the en-
vironment where vehicle is used, deposits build up in
the PCV vacuum circuit. PCV system should be in-
spected at every oil change. Service PCV system if
engine oil is discharged into air cleaner.
