CHANGE ENGINE OIL SOON
This message displays when the engine oil needs
to be changed. When you change the engine
oil, be sure to reset the CHANGE ENGINE OIL
SOON message. See Engine Oil Life System
on page 466 for information on how to reset the
message. This message clears itself after

CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the
pressure in one or more of the vehicle’s tires need
to be checked. This message also displays
LEFT FRONT, RIGHT FRONT, LEFT REAR, or
RIGHT REAR to indicate which tire needs to
be checked. You can receive more than one tire
pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button or the trip
odometer reset stem. If a tire pressure message
appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label.
See Tires on page 510, Loading Your Vehicle on
page 411, and Inflation - Tire Pressure on
page 518. The DIC display also shows the tire
pressure values for the front and rear tires
by pressing the vehicle information button. See
“DIC Operation and Displays (With DIC Buttons)”
earlier in this section. If the tire pressure is
low, the low tire pressure warning light comes on.
See Tire Pressure Light on page 253.
DRIVER DOOR OPEN
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.
