•
Service intervals that are programmable via the
keypad.
•
An audible warning and alert message to warn
the driver if the door is opened without first set-
ting the parking brake.
•
A flashing alert message that appears on the
driver message center in low engine oil pres-
sure or high coolant temperature conditions.
With the parking brake off, only the odometer and
alert screens will display. Park the vehicle and set
the parking brake to access additional screens.
The dash message center displays alert screens
when certain conditions occur. They are warnings,
cautions, or other messages that require the driver's
attention, but not all of them are critical to the opera-
tion of the vehicle. Warning messages always display
at full brightness.
More important messages take priority over less im-
portant messages. The order of priority is:
1. parking brake set (with the vehicle moving)
2. parking brake off (with the door open)
3. low oil pressure or high coolant temperature
4. hard brake warnings (if equipped with roll stabil-
ity advisor)
5. low battery voltage
6. turn signal on
7. service warnings
8.
no datalink activity
Alert Screens
NOTE: If there is more than one alert message
to display, tap any key to access the next mes-
sage, and so on, until all the messages have
been viewed.

Parking Brake On
This warning message and an audible warning come
on whenever the parking brake is applied and the
vehicle is moving faster than 2 mph (3 km/h). The
screen and audible warning go away only when the
parking brake is released, or speed is reduced below
2 mph.
Low Oil Pressure
This warning message and an audible warning come
on whenever the oil pressure falls below the mini-
mum oil pressure, whether the vehicle is idling or in
motion. Tap any key to dismiss the message.
If the fault is still active 30 seconds after the mes-
sage is dismissed, the warning message will come
on again.
High Coolant Temp
This message and an audible warning come on
whenever the engine coolant temperature exceeds
the maximum allowable temperature.
If the fault is still active 30 seconds after the mes-
sage is dismissed, the warning message will come
on again.
Low Voltage
On some vehicles, this optional message and an au-
dible warning come on whenever the ICU detects a
low voltage condition.
Turn Signal On
This warning message and audible warning come on
whenever the turn signal remains on for four minutes
or five miles of travel.
To dismiss this message, either turn off the turn sig-
nal or tap any key.
Service Warnings
Service warning screens display during the ignition
sequence and indicate that a service interval has
been reached or exceeded and maintenance is re-
quired. The messages may indicate the number of
miles (KM) or hours until the next required service or,
once passed, the number of miles (KM) or hours ago
that maintenance should have been performed.
