SPEED LIMIT: XXX MPH (SPEED LIMIT:
XXX Km/h) or ADVISORY: XXX MPH
(ADVISORY: XXX Km/h)
(On Vehicles without HUD)
This display will show the speed limit or the advised
speed as determined by the information on the map
disc in the navigation system. If there is no map disc in
the navigation system, this display will not be available.
The speed limit and speed advisory displays on the
DIC and the HUD, if equipped, are for reference only.
There may be segments of road where speed data
has not been captured or times where incorrect speed
data, or no speed data, will be displayed by the DIC and
the HUD due to the navigation system not correctly
matching the vehicle’s position to the actual road.
Be aware of this and obey posted speed limits
wherever you drive.
SPEED ALERT
This display will allow you to customize the speed alert
warning. You can choose to have no warning display,
or to have it display at the limit, at 5 mph (km/h) over
the limit, or at 10 mph (km/h) over the limit. The DIC
will toggle between OFF, AT LIMIT, +5, +10 (MPH
or Km/h). Press the reset button to make your selection.

This display can be used like a stopwatch. You can
record the time it takes to travel from one point to
another. To access the timer, press the information
button until 00:00:00 TIMER OFF displays. To turn on
the timer, press the reset button until TIMER ON displays.
The timer will then start. To turn off the timer, press the
reset button again until TIMER OFF displays. The timer
will stop and display the end timing value. To reset the
timer, press and hold the reset button after the timer has
been stopped. The display will return to zero.
BATTERY VOLTS
This display shows the current battery voltage. If the
voltage is in the normal range, the value will display.
For example, the display may read 13.2 BATTERY
VOLTS. If the voltage is low, the display will have LOW
after it. If the voltage is high, the display will have HIGH
after it. Your vehicle’s charging system regulates voltage
based on the state of the battery. The battery voltage
may uctuate when viewing this information on the DIC.
This is normal. SeeCharging System Light on page 3-61
for more information.
If there is a problem with the battery charging system,
the DIC may display a message. SeeDIC Warnings
and Messages on page 3-79andElectric Power
Management on page 3-42for more information.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the

indicated.
Some messages may not require immediate action, but
you can press the reset button to acknowledge that
you received the messages and to clear them from
the display.
Some messages cannot be cleared from the DIC display
because they are more urgent. These messages require
