Oil change reset
Press the OIL CHANGE RESET
control to reset the oil life feature to
100% (or your personalized oil reset
percentage) (at optimal driving
conditions, 100% oil life is equivalent
to a maximum of 12 000 kilometers
[7 500 miles]). After you have the oil
changed, you must press and hold
the OIL CHANGE RESET control for
five seconds. The message center will
count down for five seconds. After a
successful reset, the message center will display OIL LIFE RESET TO
100%. (If you have established a personalized oil reset percentage, the
display will show that percentage instead of 100%.) This reset procedure
should be performed only after an oil change to ensure accurate oil life
indications.
Your personalized oil reset percentage allows you to establish a smaller
oil change interval than the manufacturer's recommended interval. To
establish your personalized oil reset percentage:
1. Press and hold the OIL CHANGE RESET control and press the RESET
control while the display is still counting down the five seconds to reset.
The display will change to START OIL LIFE AT XXX%.
2. Press the OIL CHANGE RESET control until the displayed percentage
is the personalized oil reset percentage you desire. Your choices are
100%, 90%, 80%, 70%, 60%, 50%, 40% and 30%.
3. Press the RESET control to
complete the procedure. Pressing
any control other than RESET or
OIL CHANGE RESET will abort this
procedure and will not establish
your new personalized oil reset
percentage.
When your personalized oil reset
percentage has been established, it
will be used beginning with the
completion of your next OIL CHANGE RESET procedure.

Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Using the air conditioner or defroster may reduce fuel economy.
²You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant Specifications.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
