BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towingin theTires, Wheels and Loadingchapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.

In the event of a multiple warning situation, the message center will cycle
the display to show all warnings by displaying each one for 4 seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages are divided into four categories:
•They cannot be cleared until the condition is corrected.
•They will reappear on the display ten minutes from the reset if the
condition has not been corrected.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
•They reappear if the condition clears then reoccurs within the same
ignition ON-OFF cycle.
This acts as a reminder that these warning conditions still exist within
the vehicle.
