Light comes on with the ignition switch in the "ON" position
as a bulb check, but should go out shortly after engine is started. If
light remains on or comes on while driving, it indicates low oil
pressure and possible system malfunction. Have the system checked and
serviced immediately. Do not operate vehicle until cause is located
and corrected.
ALTERNATOR WARNING LIGHT
Light comes on with the ignition switch in the "ON" position
as a bulb check and goes out after engine is started. If light remains
on or comes on while driving, it indicates possible fault in the
electrical charging system. The alternator belt may be loose or
broken. Have the system checked and serviced promptly. Do not drive
vehicle if alternator belt is loose or broken.
"BRAKE" WARNING LIGHT
Light comes on with the ignition switch in the "ON" position
as a bulb check and goes out after engine is started. Light will also
come on with the parking brake fully or partially engaged. If light
remains on or comes on at any other time, it indicates low brake fluid
level in the master cylinder reservoir or the parking brake switch may
be damaged. Have the system checked and serviced immediately if brake
fluid level is low. Do not continue driving if further trouble is
experienced.
"CHECK ENGINE" WARNING LIGHT (IF EQUIPPED)
Light is designed to come on briefly with the ignition switch
in the "ON" position as a bulb check. If light remains on or comes on
while driving, it indicates fault in an exhaust gas related component
and the system is not functioning properly. Have the system checked
and serviced as soon as possible.
"MAINTENANCE REQUIRED" WARNING LIGHT (IF EQUIPPED)
Light comes on at 50,000 miles, 80,000 miles, 100,000 miles
and 120,000 miles (150,000 miles on 1990-91 models) as a service
reminder that it is time for the periodic maintenance of the emission
control system. Have the system inspected and serviced as necessary
when light comes on. Continued operation of vehicle without having
system serviced after warning light comes on may adversely affect
proper performance of the emission control system. Reset warning
light, after the system has been checked, by pushing the reset switch
in front of the combination meter. Remove the warning light bulb after
the last maintenance service at 120,000 miles (150,000 miles on 1990-
91 models).
"A/T TEMPERATURE" WARNING LIGHT (IF EQUIPPED)
Light comes on when the automatic transmission fluid
temperature becomes abnormally high. If light comes on, reduce engine
speed, stop car and put it in "P" (Park) position. Leave engine
running until light goes out. Normal vehicle operation may be resumed
after light has gone out. If light does not go out, have the system
checked and serviced as necessary.
WHEEL LOCK INDICATOR LIGHT (IF EQUIPPED)
Light comes on when automatic free-wheeling hubs are locked.
If ignition is turned off, indicator light will not come on when

LUBRICATION
TRANSAXLE/TRANSMISSION SERVICE INTERVALS
Check fluid level every 12 months or 15,000 miles. Change
fluid and filter every 30,000 miles. If vehicle is operated under
severe condition, change fluid more often. If severe darkening of
fluid and strong odor are noted, bands should also be adjusted (if
equipped).
TRANSFER CASE SERVICE INTERVALS
On 4WD and AWD models, change transfer case fluid every 30,
000 miles.
CHECKING FLUID LEVEL
TRANSAXLE/TRANSMISSION
1) Park vehicle on level area. Ensure oil is at normal
operating temperature, parking brake is engaged, and engine is at
idle. Move gear selector through each position, stopping briefly in
each position.
2) Place gear selector in Neutral, and clean area around
dipstick tube. Ensure fluid level is between lower and upper marks,
but never over upper mark, in HOT range. Add or drain fluid if
necessary.
Page 1174 of 1333
CAUTION: If severe darkening of fluid and strong odor are noted,
change fluid and filter, and adjust bands.
TRANSFER CASE (3000GT)
Lubricant level should be approximately .5" (13 mm) below
fill hole on side of transfer case.
TRANSFER CASE (ALL OTHERS)
Lubricant level should be to bottom of fill hole on side of
transfer case.
RECOMMENDED FLUID
TRANSAXLE/TRANSMISSION
Use Chrysler Plus/Mitsubishi Plus ATF, Dexron and Dexron-II
ATF.
