Relearn Remote Key
This display allows you to match Remote Keyless Entry
(RKE) transmitters to your vehicle. This procedure will
erase all previously learned transmitters. Therefore,
they must be relearned as additional transmitters.
To match an RKE transmitter to your vehicle:1. Press the vehicle information button until PRESS
VTO RELEARN REMOTE KEY displays.
2. Press the set/reset button until REMOTE KEY LEARNING ACTIVE is displayed.
3. Press and hold the lock and unlock buttons on the first transmitter at the same time for about
15 seconds.
On vehicles with memory recall seats, the
first transmitter learned will match driver 1 and
the second will match driver 2.
A chime will sound indicating that the transmitter is
matched.
4. To match additional transmitters at this time, repeat Step 3.
Each vehicle can have a maximum of
eight transmitters matched to it.
5. To exit the programming mode, you must cycle the key to LOCK/OFF.

Trip Odometer Reset Stem Menu Items
Use the trip odometer reset stem to view the odometer
and trip odometer. The Language selection and Engine
Hours display can also be accessed with the trip
odometer reset stem.
Odometer
Press the trip odometer reset stem until ODOMETER
displays. This display shows the distance the vehicle
has been driven in either miles (mi) or kilometers (km).

Trip Odometer
Press the trip odometer reset stem until TRIP displays.
This display shows the current distance traveled in
either miles (mi) or kilometers (km) since the last reset
for the trip odometer.
The trip odometer can be reset to zero by pressing and
holding the trip odometer reset stem while the 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 miles (kilometers) 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 the
trip odometer reset stem for at least four seconds. The
trip odometer will display the number of miles (mi) or
kilometers (km) 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
5 miles (8 km) before it is started again, and then the
retro-active reset feature is activated, the display will
show 5 miles (8 km). As the vehicle begins moving, the
display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
Language
This display allows you to select the language in which
the DIC messages will appear. To select a language:1. Press the trip odometer reset stem until ODOMETER displays.
2. While in the ODOMETER display, press and hold the trip odometer reset stem for three seconds until
the currently set language displays.
3. Continue to press and hold the trip odometer reset stem to scroll through all of the available
languages.
The available selections are ENGLISH (default),
FRANCAIS (French), ESPANOL (Spanish), and
NO CHANGE.
4. Once the desired language is displayed, release the trip odometer reset stem to set your choice.
Engine Hours
To display the ENGINE HOURS, place the ignition in
LOCK/OFF or ACC/ACCESSORY, then press and hold
the trip odometer reset stem for four seconds while

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” underDIC
Warnings and Messages
on page 4‑61. You should
change the oil as soon as you can. See Engine Oilon
page 6‑17. 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
on page 7‑3for
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 6‑20.

Your vehicle may have this display. To access this
display, the vehicle must be in P (Park). If your vehicle
has the Tire Pressure Monitor System (TPMS), after
rotating the tires or after replacing a tire or sensor, the
system must re-learn the tire positions. To re-learn the
tire positions, see
Tire Pressure Monitor System
on
page 6‑73. See Tire Inspection and Rotationon
page 6‑78and DIC Warnings and Messageson
page 4‑61for more information.
