Vehicle Information Menu Items
T
(Vehicle Information): Press this button to scroll
through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an estimate
of the oil's remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system
will alert you to change the oil on a schedule consistent
with your driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the display.
See "CHANGE ENGINE OIL SOON" under DIC
Warnings and Messages on page 3-60. You should
change the oil as soon as possible. See Engine Oil
on page 5-17. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. See Scheduled Maintenance on page 6-4 for
more information.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, see Engine Oil
Life System on page 5-20.
Units
Press the vehicle information button until UNITS
displays. This display allows you to select between
English or Metric units of measurement. Once in this
display, press the set/reset button to select between
ENGLISH or METRIC units.
Park Assist
If your vehicle has the Ultrasonic Rear Parking Assist
(URPA) system, this display allows the system to
be turned on or off. Press the vehicle information button
until PARK ASSIST displays. Once in this display,
press the set/reset button to select between ON or OFF.
If you choose ON, the system will be turned on. If you
choose OFF, the system will be turned off. The URPA
system automatically turns back on after each vehicle
start. When the URPA system is turned off and the
vehicle is shifted out of PARK (P), the DIC will display
the PARK ASSIST OFF message as a reminder that the
system has been turned off. See DIC Warnings and
Messages on page 3-60 and Ultrasonic Rear Parking
Assist (URPA) on page 2-38 for more information.
