Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. It is also used
to display driver personalization features and
warning/status messages. The DIC display is located on
the instrument panel cluster. The DIC buttons are
located on the steering wheel.
The DIC comes on when the ignition is on. After a short
delay the DIC will display the current driver and the
information that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will appear
on the display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.

pressing the four buttons located on the steering wheel.

(Fuel Information):Press this button to scroll
through the range, average fuel economy, instant fuel
economy, and engine oil life.
Fuel Range
Press the fuel information button until RANGE appears to
display the remaining distance you can drive without
refueling. It is based on fuel economy and the fuel
remaining in the tank. The display will show FUEL LEVEL
LOW and a chime will sound if the fuel level is low. The
check gages warning light on the instrument panel cluster
will also be illuminated. SeeCheck Gages Warning Light
on page 3-38for more information.
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.
Fuel range cannot be reset.
Average Fuel Economy
Press the fuel information button until AVG. ECON
appears in the display. Average fuel economy is how
many miles per gallon (MPG), kilometers per liter (km/L),
or liters per 100 kilometers (L/100 km) your vehicle is
getting based on current and past driving conditions.
Press and hold the select button while AVG. ECON is
displayed to reset the average fuel economy. Average
fuel economy will then be calculated starting from
that point. If the average fuel economy is not reset, it
will be continually updated each time you drive.
Instant Fuel Economy
Press the fuel information button until INST. ECON
appears in the display. Instant fuel economy is
how many miles per gallon (MPG), kilometers per
liter (km/L), or liters per 100 kilometers (L/100 km) your
vehicle is at the particular moment in time. The
instant fuel economy cannot be reset.

When operating the top in low temperatures, such as
below 32°F (0°C), the time needed to cycle the top will
increase. This may cause the top movement to stop

convertible top switch and press it again to continue the
cycle. Make sure nothing is blocking the path of the
top before pressing the switch again. It may be
necessary to do this several times to complete the
cycle, depending on the outside temperature. See
Convertible Top on page 2-45for more information.
Notice:If you operate the convertible top switch
continuously while the ignition is in ACCESSORY,
the battery will drain and you might not be able
to start your vehicle. Do not use the convertible top
switch for extended periods of time when the
ignition is in ACCESSORY.

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may feel
the brakes vibrate, or you may notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
(Automatic Transmission)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the rear wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also up-shift the transmission to limit wheel spin.
You may feel or hear the system working, but this
is normal.If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-10.
The Traction Control System operates in all transmission
shift lever positions except for FIRST (1). This is
normal. The system is deactivated when the
transmission is shifted into FIRST (1). In this situation,
the traction control system warning light on the
instrument panel cluster will come on. This is normal.
The system can upshift the transmission only as high as
the shift lever position you’ve chosen, so you should
use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-19.
When the system is on,
this warning light will come
on to let you know if
there’s a problem.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
