The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE

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 System1. Using the DIC controls on the right side of the steering wheel,
display REMAINING OIL LIFE
on the DIC. See Driver

When remaining oil life is low,
the CHANGE ENGINE OIL

the display.
2. Press
Von the DIC controls
and hold down for a few
seconds to clear the CHANGE
ENGINE OIL SOON message
and reset the oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is changed. It cannot be reset
accurately until the next oil
change.
See Engine Oil Life System 0253.
Driving for Better Fuel

Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible:

desired temperature after the
engine is started, or turn them
off when not required.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time.
. When road and weather
conditions are appropriate, use
cruise control. .
Always follow posted speed
limits or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated.
. Combine several trips into a
single trip.
. Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.

filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
