1-32 In Brief
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
SeeTire Pressure Monitor System
on page 10‑57.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change. Resetting the Oil Life System
To reset the Engine Oil Life System
on most vehicles:
1. Display OIL LIFE REMAINING
on the DIC. If the vehicle does
not have DIC buttons, the
vehicle must be in P (Park) to
access this display.
2. Press and hold the SET/RESET button on the DIC, or the trip
odometer reset stem if the
vehicle does not have DIC
buttons, for more than
five seconds. The oil life will
change to 100%.
On all vehicles, the Engine Oil Life
System can be reset as follows:
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds. 3. Display OIL LIFE REMAINING
on the DIC. If the display shows
100%, the system is reset.
See Engine Oil Life System on
page 10‑9.
Fuel E85 (85% Ethanol)
Vehicles that have a yellow fuel cap
can use either unleaded gasoline or
ethanol fuel containing up to 85%
ethanol (E85). See Fuel E85 (85%
Ethanol) on page 9‑68. For all other
vehicles, use only the unleaded
gasoline described under
Recommended Fuel on page 9‑66.
