DIC Buttons
The buttons are the trip/fuel, vehicle
information, customization, and set/reset
buttons. The button functions are detailed in
the following pages.
3:Press this button to display the
odometer, trip odometers, fuel range,
average economy, fuel used, timer, average
speed, and digital tachometer.
T: Press this button to display the oil
life, rear park assist, units, tire pressure
readings for vehicles with the Tire Pressure
Monitor System (TPMS), engine hours, Tire
Pressure Monitor System (TPMS)
programming for vehicles with the TPMS and without a Remote Keyless Entry (RKE)
transmitter, and compass zone and compass
calibration on vehicles with this feature.
U:
Press this button to customize the
feature settings on the vehicle. See Vehicle
Personalization 086 for more information.

Trip/Fuel Menu Items
3: Press this button to scroll through
the following menu items:
Odometer
Press
3until XX km (mi) displays. This
display shows the distance the vehicle has
been driven in either kilometers (km) or
miles (mi).
Trip Odometers
Press
3until A or B displays. This
display shows the current distance traveled
in either kilometers (km) or miles (mi) since
the last reset for each trip odometer. Both
trip odometers can be used at the
same time. Each trip odometer can be reset to zero
separately by pressing
Vwhile the desired
trip odometer is displayed.
The trip odometer has a feature called the
retro-active reset. This can be used to set
the trip odometer to the number of
kilometers (miles) driven since the ignition
was last turned on. This can be used if the
trip odometer is not reset at the beginning
of the trip.
To use the retro-active reset feature, press
and hold
Vfor at least four seconds. The
trip odometer will display the number of
kilometers (km) or miles (mi) driven since
the ignition was last turned on and the
vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate
mileage. For example, if the vehicle was
driven 8 km (5 miles) before it is started
again, and then the retro-active reset feature
is activated, the display will show 8 km
(5 miles). As the vehicle begins moving, the
display will then increase to 8.1 km
(5.1 miles), 8.2 km (5.2 miles), etc.
If the retro-active reset feature is activated
after the vehicle is started, but before it
begins moving, the display will show the
number of kilometers (km) or miles (mi) that
were driven during the last ignition cycle.

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. You should change
the oil as soon as possible. SeeEngine Oil
0 184. In addition to the engine oil life
system monitoring the oil life, additional
maintenance is recommended. See
Maintenance Schedule 0249.
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 0186.

Units
Press
Tuntil UNITS displays. This display
allows you to select between metric or
English units of measurement. Once in this
display, press
Vto select between METRIC
or ENGLISH units.
Tire Pressure
If the vehicle has the Tire Pressure Monitor
System (TPMS), the pressure for each tire
can be viewed in the DIC. The tire pressure
will be shown in either kilopascals (kPa) or pounds per square inch (psi). Press
Tuntil
the DIC displays FRONT TIRES PSI (kPa)
LEFT ## RIGHT ##. Press
Tagain until the
DIC displays REAR TIRES PSI (kPa) LEFT ##
RIGHT ##.
If a low tire pressure condition is detected
by the system while driving, a message
advising you to check the pressure in a
specific tire will appear in the display. See
Tire Pressure 0216.
If the tire pressure display shows dashes
instead of a value, there may be a problem
with the vehicle. If this consistently occurs,
see your dealer for service.
Engine Hours
Press
Tuntil ENGINE HOURS displays. This
display shows the total number of hours the
engine has run.
Relearn Tire Positions
The vehicle may have this display. To access

the Spare Tire”underTire Changing

The outer tire on a dual wheel setup
generally wears faster than the inner
tire. Tires last longer and wear more
evenly if they are rotated. See Tire
Inspection 0220 and
Tire Rotation 0220. Also see
Maintenance Schedule 0249.
If the full-size spare tire is part of the
tire rotation, make sure the tire rotated
into the spare position is stored
securely. Push, pull, and then try to
rotate or turn the tire. If it moves, use
the wheel wrench/hoist shaft to tighten
the cable. See Tire Changing0228.
Use this rotation pattern when rotating
the tires if the vehicle has dual rear
wheels.
When installing dual wheels, check that
the vent holes in the inner and outer
wheels on each side are lined up.
Adjust the front and rear tires to the
recommended inflation pressure on the
Tire and Loading Information label after
the tires have been rotated. See Tire
Pressure 0216 and
Vehicle Load Limits 0131.
Reset the Tire Pressure Monitor System.
See Tire Pressure Monitor Operation
0 217. Check that all wheel nuts are properly
tightened. See
“Wheel Nut Torque”
under Capacities and Specifications
0 258, and “Removing the Flat Tire and
Installing the Spare Tire” underTire
Changing 0228.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
cause wheel nuts to become loose
over time. The wheel could come off
and cause a crash. When changing a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, a cloth
or paper towel can be used; however,
use a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the inner diameter of the
wheel hub opening with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or rust
build-up.
