maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as

Each trip odometer can be reset to
zero separately by pressing and
holding the trip odometer reset stem
while the desired trip odometer is
displayed.
The trip odometer has a feature
called the retroactive 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 retroactive reset feature,
press and hold the trip odometer
reset stem for 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 mi) before it is started
again, and then the retroactive reset
feature is activated, the display will
show 8 km (5 mi). As the vehicle
begins moving, the display will then
increase to 8.2 km (5.1 mi), 8.4 km
(5.2 mi), etc.
If the retroactive 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) driven
during the last ignition cycle.
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 thecurrent 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”
under Engine Oil Messages on
page 5‑40. You should change the
oil as soon as you can. See Engine
Oil on page 10‑8. In addition to the
