Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
You may wonder what happens if a vehicle has to have
a new odometer installed. The new one may read
the correct mileage. This is because your vehicle's
computer has stored the mileage in memory.
Trip Odometers
The trip odometer can record the number of miles or
kilometers traveled for up to two trips.
The trip odometer button is
located to the left of the
steering wheel on the
instrument panel.The two trip modes are indicated by Trip A and Trip B.
In order to change from one mode to the other,
press the A/B portion of the TRIP button.
By pressing the bottom of this button, you can tell how
many miles have been recorded on either Trip A or
Trip B since you last set the odometer back to zero.
Press the RESET part of the button until zeros appear
to reset each trip mode.
If your vehicle is ®rst sold in the United States, the trip
odometer will return to zero after 999.9 miles
(1 609 km). If your vehicle is ®rst sold in Canada, the
trip odometer will return to zero after 1 999.9 km
(1,242 miles). The RESET TRIP A/B button only resets
the trip mode (A or B) that is being displayed. Each
trip mode must be reset individually.

Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.To see the display, press the INFO button several times
until ENGINE OIL LIFE appears. If you see 99%
ENGINE OIL LIFE, 99 percent of your current oil life
remains.
The DIC may display a CHANGE ENGINE OIL
message. For more information, see
Scheduled
Maintenance on page 6-4. If you see CHANGE ENGINE
OIL, it means the oil life is gone and you should
change the oil right away. The system doesn't check
how much oil you have, so you'll still have to check for
that. To see how, see
Engine Oil on page 5-13.
When the oil is changed, you'll need to reset the system.
See
Engine Oil on page 5-13. Always keep a written
record of the mileage and date when you changed
your oil.
