On vehicles with the Integrated Trailer Brake Control

GAIN and OUTPUT display.
TRAILER GAIN shows the trailer gain setting. This
setting can be adjusted from 0.0 to 10.0 with either a
trailer connected or disconnected. To adjust this setting,
see "Integrated Trailer Brake Control System" under
Towing a Trailer on page 4-53 for more information.

a trailer with electric brakes is connected. Output is
displayed in 0 to 10 bars. Dashes may appear in
the OUTPUT display. See "Integrated Trailer Brake

Oil Life
To access this display, the vehicle must be in P (Park).
Press the trip odometer reset stem 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 3-66. You should change the
oil as soon as you can. 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 (Gasoline Engine) on page 6-4 for more
information.
Remember, you must reset the OIL LIFE display yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE display 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.
