The range calculates the remaining distance you can
drive without refueling. It's based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 krn), the display
will read RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions.
As your driving
conditions change, this data is gradually updated.
Resetting the fuel range causes the fuel economy data to
be updated immediately. Press RESET to reset the
fuel range.

Downloaded from www.Manualslib.com manuals search engine SERVICE RIDE CONTROL: This message is used to
indicate to the driver that the Selective Real Time
Damping (SRTD) system has detected a malfunction
and that the system must be serviced. The SERVICE
RIDE CONTROL message will always come on when a
failure is detected by the Selective Real Time Damping
system. If
a fault is present in the SRTD which causes
the shocks to be in their full soft condition, the
SERVICE RIDE CONTROL, SHOCKS
INOPERATIVE and MAXIMUM
80 MPH (129 km/h)
will display together. You will never get a SHOCKS
INOPERATIVE and MAXIMUM SPEED
80 MPH
(129

SHOCKS INOPERATIVE: You will hear four chimes
when this message is displayed. To acknowledge that
you have read the message and to remove it from the
display, press RESET. The message will reappear every
10 minutes until this condition changes.
This message indicates that a malfunction is present in
the Selective Real Time Damping system which is

Downloaded from www.Manualslib.com manuals search engine If the engine coolant exceeds 255 “F (124”C), this
message is displayed. If you have been operating your
vehicle under normal driving conditions, you should
pull off from
the road, stop your vehicle and turn off the
engine as soon as possible. You can monitor the coolant
temperature with the GAGES button on the DIC or the
engine coolant gage on the instrument panel cluster. See
“Engine Overheating” in the Index.
HIGH OIL TEMPERATURE REDUCE ENGINE
RPM: You will hear four chimes when this message is
displayed. To acknowledge the warning, press the
RESET button. After you press the RESET button, a
message will be displayed and you will hear a chime
every minute until this condition changes. If you do not
press RESET, the message will remain on the digital
display until the condition changes.
If the engine oil temperature exceeds
320°F (1 60” C),
this message is displayed. You should check the engine
coolant temperature and engine oil level. If your engine
is too hot, see “Engine Overheating’’ in the Index. Your
vehicle may need service,
so see your dealer. You can
monitor the oil temperature with the GAGES button on
the DIC.
HIGH TRANS TEMP: You will hear four chimes
when this message is displayed. To acknowledge this
warning, press the RESET button. After you press the
RESET button, the message will be displayed every
10 minutes until the condition changes. If you do not
press RESET, the message remains on the display until
the condition changes.
If the transmission fluid temperature rises above 263°F
(128°C) or rises rapidly, this message is displayed. The
transmission may shift gears or apply the torque
converter clutch to reduce the fluid temperature. Driving
aggressively or driving on long hills can cause the
transmission fluid temperature to be higher than normal.
If this message appears, you may continue to drive at a
slower speed. You should also monitor the transmission
fluid temperature and allow it to cool to at least 230°F
(1 10°C). The transmission fluid temperature can be
monitored with the GAGES button on the DIC. See
“Automatic Transmission Fluid” in the Index. You
should also check the engine coolant temperature.
If it is
also hot, see “Engine Overheating” in the Index.
If the HIGH TRANS TEMP message is displayed
during normal vehicle operation on flat roads, your
vehicle may need service. See your dealer for an
inspection.

+' LOWER: This setting directs most of the air
through the lower ducts to the floor area of the vehicle with some of the air also directed toward the windshield
and side window vents.
+# DEFOG: This setting divides the air between the
windshield and lower outlets with a small amount directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
DEFROST Use this setting to quickly remove fog
or frost from the windshield. This setting directs most of
the airflow to the windshield with
a small amount
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning and the rear window defogger operation.
FRESH AIR: Press this button and it will bring
outside air into your vehicle. The light on the button will
come on when operating. Use this setting while trying to
defrost or defog windows to help clear moisture.
RECIRCULATE: Press this button to limit the
amount of fresh air entering your vehicle by
recirculating most of the
air inside your vehicle. The
light on the button will come on when operating. This
setting is helpful when you are trying to cool the air
quickly or to limit odors entering your vehicle.
RECIRCULATE cannot be used while in the DEFROST
or
DEFOG modes.
e A/C: This button turns the air conditioning
compressor
off or on under most conditions. The light
on the A/C button comes on when the compressor is
operating. The air conditioning does not operate at
temperatures below approximately
35 OF to 40°F (2" C
to 4°C). The air conditioning cools and dehumidifies the
air coming into the vehicle. The air conditioning cannot
be turned
off in DEFROST as it helps to remove
moisture from the vehicle. It also helps to keep the
windows clear.
The air conditioning may be forced
off at high engine
speeds
or high engine oil or coolant temperatures.

Downloaded from www.Manualslib.com manuals search engine When adjusting the temperature, start with a driver-set
temperature of
73°F (23 "C) until you determine your
comfort zone. If you choose
60°F (16"C), the system
will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose
90°F (32"C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob to the right for
warmer air
on the passenger's side, to the left for cooler
air. If the driver-set temperature is set at
60°F (1 6 " C) or
90 OF (32 " C), turning the passenger knob has no effect
because the system is locked at a maximum setting.
Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five second display of the current settings, only the word
AUTO and the outside
temperature will be shown on the digital display. The
system will operate to achieve your comfort set
temperature as quickly as possible. If you have set the
driver temperature at
60°F (16°C) or 90°F (32"C), the
system will not operate automatically until a different
temperature is selected. The AUTO control system
works best with the windows up and the removable roof
installed or the convertible top up.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather (below
32 OF/ 0 " C) and you have set the driver
temperature at
73°F (23°C) and have selected the AUTO
mode. The system will automatically adjust the
temperature output to maximum heating. The fan will start
at a low speed. This is to avoid blowing cold
air into the
vehicle. The length of the delay depends on the amount of
time since the engine was last started, the outside
temperature and the engine coolant temperature. As the
coolant warms up, the fan speed will gradually increase.
Air will flow to the floor with some air to the windshield
to prevent fogging under most normal conditions.
