CHANGE ENGINE OIL SOON
This message will display 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 441 for information on how to
reset the message. This message will clear itself
after 10 seconds until the next ignition cycle
or until the message is reset. See Engine Oil on
page 438 and Scheduled Maintenance on
page 555 for more information.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display when the
pressure in one or more of the vehicle's tires need
to be checked. This message will also display
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 your Tire Loading Information Label.
See Tires on page 482, Loading Your Vehicle on
page 390, and Inflation - Tire Pressure on
page 490. 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 will
come on. See Tire Pressure Light on page 235.
DRIVER DOOR OPEN
If the driver's door is not fully closed and the
vehicle is in a drive gear, this message will display
and a chime will sound. 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.
