1-26 In Brief
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. 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. It is the
driver’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑58.
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 10‑10.
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and 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 9‑64. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑62.

Compass
The vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer will
set the correct zone for your
location.Under certain circumstances,
such as during a long-distance,
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:
Compass Variance (Zone)
Procedure
1. Do not set the compass zone
when the vehicle is moving. Only
set it when the vehicle is in
P (Park). Press the vehicle information
button until PRESS
VTO
CHANGE COMPASS ZONE
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
CHANGE COMPASS ZONE
displays.
2. Find the vehicle's current location and variance zone
number on the map.
Zones 1 through 15 are
available.

3. Press the set/reset button toscroll through and select the
appropriate variance zone.
4. Press the trip/fuel button until the vehicle heading, for
example, N for North, is
displayed in the DIC. Or, if the
vehicle does not have DIC
buttons, press and hold the trip
odometer reset stem for
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass. See
“Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger. It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB
or cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone is
set to the variance zone in which
the vehicle is located. See
“Compass Variance (Zone)
Procedure” earlier in this
section.
Do not operate any switches
such as window, sunroof,
climate controls, or seats during
the calibration procedure.
2. Press the vehicle information button until PRESS
VTO
CALIBRATE COMPASS
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
CALIBRATE COMPASS
displays.

CIRCLES. Drive the vehicle in

Power Outlet 110 Volt
Alternative Current
The vehicle may have a power
outlet that can be used to plug in
electrical equipment that uses a
maximum limit of 150 watts.
The power outlet is located on the
rear of the center console.An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is in
ON/RUN and equipment requiring
less than 150 watts is plugged into
the outlet, and no system fault is
detected.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the Remote
Accessory Power (RAP) off and
then back on. See
Retained
Accessory Power (RAP) on
page 9‑27 The power outlet is not designed for
and may not work properly, if the
following are plugged in:
.Equipment with high initial
peak wattage such as:
compressor-driven refrigerators
and electric power tools.
.Other equipment requiring
an extremely stable power
supply such as:
microcomputer-controlled
electric blankets, touch sensor
lamps, etc.
