Engine Coolant Temperature
Warning Light
This light tells you that
your engine has
overheated. As a check,
the light should come
on for a few seconds when
you start your engine.
If this light comes on and stays on, you should stop your
vehicle and turn the engine off as soon as possible. A
warning chime should also sound if this light comes on.

This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
That reading means the same thing as the warning
light – the engine coolant has overheated. SeeEngine

To reset the average fuel economy, press the INFO
button until the MPG AVG is displayed on the DIC.
Press and hold the INFO RESET button until both the
fuel data display and DIC display reads 0.0.
The RANGE display shows how far the computer thinks
you can travel with the fuel that is in the tank. The
computer does not know what driving conditions will be
like for the rest of your trip, so the range is estimated
based on the recent fuel economy. Therefore, the range
reading may change as your driving habits change.
Going from city to highway driving may increase
the range reading.
On the analog cluster, fuel data can be obtained by
pressing the INFO button. SeeDriver Information
Center (DIC) on page 3-62.Driver Information Center (DIC)
This display gives you the status of many of your
vehicle’s systems. The DIC is also used to display driver
personalization features and warning/status messages.
All messages will appear in the DIC display, located
at the bottom of the instrument panel cluster.
DIC Controls and Displays
The Driver Information Center (DIC) buttons are located
to the right of the steering wheel on the instrument

DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle’s systems. Vehicles that
are rst sold in Canada will have a number after
each message. This number helps to identify the
problem. You must then press INFO or INFO RESET to
clear the display screen for further use. However, be
sure to take any message that appears on the display
screen seriously and remember that pressing the
INFO or INFO RESET button will only make the
message disappear, not the problem.

German, Spanish and Japanese. Contact your dealer to
have the language display adjusted for your vehicle.BATTERY NOT CHARGING – 7:This message will
appear if the battery is not being charged. Have
the electrical system checked by your dealership at your
earliest convenience.
BATTERY SAVER ACTIVE – 27:This message is
displayed when the vehicle has detected that the battery
voltage is dropping beyond a reasonable point. The
battery saver system will start reducing certain features
of the vehicle that you may not be able to notice. At
the point that features are disabled, this message
is displayed. It means that the vehicle is trying to save
the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.
BATTERY VOLTAGE HIGH – 8:This message shows
that the electrical charging system is overcharging
(more than 16 volts). To avoid being stranded, have the
