FUEL USED: Shows the total amount of fuel used
since you last reset this mode. The amount can be
displayed in gallons
or liters.
AVG ECON: Shows your average fuel economy since
you last reset this mode.
OIL LIFE: Shows a percentage of the oil’s remaining
useful life. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. Each time
you get an oil
change, be sure to reset this function
so that it will give
you an accurate percentage.
To reset the Oil Life Indicator after the oil has been

will appear next to that
door on the vehicle outline.

open, a light will outline the trunk
area on your
vehicle outline.

See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle.
To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can
turn the

turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle”
in the Index.)
To turn the system off,
press the TCS button on
the far right end of the
trip computer.
The traction control system warning light will come
on and stay on. If the system is limiting wheel spin
when you press the button, the warning light will come
on -- and the system will shut-off instantly. It will wait
until there’s no longer
a current need to limit
wheel spin.
You can
turn the system back on at any time by pressing
the button again. The traction control system warning
light should go
off.
