DIC Messages
These messages will appear if there is a problem sensed
in one of your vehicle's systems. Vehicles that are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
APPLY BRAKE TO SHIFT
appear if your vehicle is in PARK (P) for about 15
seconds and the brake is not pressed in. To remove this
message from the DIC display, hold the OFF and the
blue (cooler) buttons on the digital cluster control panel
for about five seconds. On the analog climate control
panel, press the OFF button (next to the MODE button)
and the down arrow on the PASS TEMP button for
about five seconds. Hold the same two buttons to
display the message again.
BATTERY NOT CHARGING

electrical system checked by your dealership at your
earliest convenience.
