light stays on, it may be an indication that the parking
brake has not been released, or there is a low brake fluid
level. If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full mark on
the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction. In this case, the light will
remain on until the condition has been corrected. If the
parking brake is applied, the light will flash when the
gear position is out of park for automatic transmissions.
If brake failure is indicated, immediate repair is neces-
sary. Operating the vehicle in this condition is danger-
ous!
22. Low Washer Fluid Indicator
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled. 23. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.

and blower speed to maintain comfort. High blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates on the inside of windows can increase the
rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration of engine coolant to distilled water is
recommended. See coolant section of Owner’s manual. When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and depress the accelerator slightly
for fast idle operation.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

STARTING PROCEDURES
The starter should not be operated for more than 15
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in NEUTRAL and depress clutch pedal to the floor before
starting the vehicle. This vehicle is equipped with a
clutch interlocking ignition system. It will not start unless
the clutch is depressed.
Automatic Transmission
Start the engine with the shift lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully.

WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
AUTOMATIC TRANSMISSION
Automatic Transmission
The electronic PRNDL on the instrument cluster indicates
the transmission gear selected. The selector lever is
mounted on the right side of the steering column. To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull selector lever toward you
when shifting into Reverse, Second, First or Park, or
when shifting out of Park.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress the brake
pedal first, before moving the gear selector out of PARK.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
“P” Park
Supplements parking brake by locking the transmission.
Engine can be started in this range. Never use Park while
vehicle is in motion. Apply parking brake when leaving
vehicle in this range. Always apply parking brake first,
then place selector in Park position.
204 STARTING AND OPERATING
Page 206 of 408

“N” Neutral
Shift to Neutral when vehicle is standing for prolonged
periods with engine running. Engine may be started in
this range. Set the parking brake if you must leave the
vehicle.
“D” Drive
For most city and highway driving.
“2” Second
For driving slowly in heavy city traffic or on mountain
roads where more precise speed control is desirable. Use
it also when climbing long grades, and for engine brak-
ing when descending moderately steep grades. To pre-
vent excessive engine speed do not exceed 45 miles per
hour (72 km/h) in this range. “1” First
For driving up very steep hills and for engine braking at
low speeds 25 mph (40 km/h) or less when going down
hill. To prevent excessive engine speed do not exceed 25
mph (40 km/h) in this range.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth (if equipped) speed
(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:
•the transmission selector is in Drive;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph (48
km/h);
•the “TOW/HAUL” switch has not been activated;
206 STARTING AND OPERATING
Page 207 of 408

•transmission has reached normal operating tempera-
ture.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion. The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use “TOW/HAUL” Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the “TOW/HAUL” button. This will improve
STARTING AND OPERATING 207

performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in “TOW/HAUL” mode, 5th gear (if
equipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The “TOW/HAUL” light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the “TOW/HAUL” mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy is included
in all automatic transmissions. A clutch within the torque
converter engages automatically at a calibrated speed at light throttle. It engages at higher speeds under heavier
acceleration. This may result in a slightly different feeling
or response during normal operation in high gear. When
the vehicle speed drops below a calibrated speed, or
during acceleration, the clutch automatically and
smoothly disengages. The feature is operational in Over-
drive and in Drive.
NOTE:
The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Pressing the TOW/HAUL button, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
NOTE: If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
