Battery Replacement
Under normal use, the battery in your key fob
transmitter should last about 18 months.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.

AVERAGE 5.3 L/100 km

yellowblue
2-94
The average fuel economy is viewed as a long-term
approximation of your overall driving conditions. If you
press RESET in this mode while you're driving, the
system will begin figuring fuel economy from that point
in time.
Press FUEL again to display instantaneous fuel
economy, such as:

INST. 20.1 MPG or

INST. 5.3 L/100 km
Press FUEL again to display the range, such as:

RANGE 20 MI or

RANGE 32 km
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 km), 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.2 GAGES
The GAGES button allows you to scroll through the
functions listed below when you press it.
Press the GAGE button to display the oil pressure,
such as:

OIL PRESSURE 40 PSI or

3-4 Automatic Electronic Dual Climate Control
System (If Equipped)
Your vehicle may be equipped with an Automatic
Electronic Dual Climate Control System. This system
can automatically adjust and control temperature output,
fan speed, air delivery mode, air conditioning operation
and air intake. You can use the AUTO (automatic)
setting or override the automatic operation with
manual control settings. The control settings will be
remembered each time you turn the ignition off
and restart in the same settings. You can use the
memory option to store and recall your settings.
(See ªMemoryº in the Index.)Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric) on
the Driver Information Center (DIC). When you start
the vehicle, the display will show the current fan speed,
air delivery mode and the driver
-set temperature for
approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver's and passenger's side of the vehicle. Turn the
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Whenever you turn this knob, the temperature will be
displayed for approximately five seconds along with the
current fan speed and air delivery mode.

yellowblue
3-5
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 clockwise for
warmer air on the passenger's side, counterclockwise for
cooler air. If the driver
-set temperature is set at 60
F
(16
C) or 90
F (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
F/ 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.

3-6
As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating
from the sun or outside temperature increases, the
system may switch to other air delivery modes
(typically DEFOG or BI
-LEVEL).
A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather (above 70
F/ 21
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 cooling. The blower
will start at a low speed momentarily to push the hot air
to the floor of the vehicle and then go to a higher blower
speed with cold airflow out of the instrument panel
outlets. A small amount of airflow will continue through
the lower ducts to cool the floor area.The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set temperature, the
fan speed will decrease and the temperature output may
become warmer. The air intake may shift from
recirculation to fresh air mode. If the interior continues
to cool due to a decrease in the amount of heat the
vehicle is absorbing from the sun or a decrease in the
outside temperature, the system could switch to other air
delivery modes (typically BI
-LEVEL or DEFOG).
Manual Settings
With the Automatic Electronic Dual Climate Control
System, there are several manual settings you can use to
control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.
