Driver Influenced Gear Selection:
.Aggressive driving will influence both the
upshift and downshift points in all modes.
.Criteria which have influence are: driving
mode, accelerator, brakes, lateral and
longitudinal loading.
.Changes in gear selection behavior due to
aggressive driving can include:
‐Downshifting early with higher rpm’s
during aggressive braking (i.e. entering
a corner)
‐ Altering upshifts while experiencing
lateral acceleration
‐ Not upshifting when the accelerator is
released to avoid unnecessary shifts if
the accelerator is re-applied
‐ Recognizing sporty driving and
anticipate upcoming corners with the
appropriate gear selection entering and
exiting
.Driver Modes
‐Driver influenced changes are effective
in all driving modes, however the
aggressiveness of the transmission
response will increase between Tour,
Sport, and Track Modes respectively. Active Fuel Management (engine cylinder
shuts off)

skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer's warnings
about the use and disposal of oil products.
Used oil can be a threat to the environment.
If you change your own oil, drain all the oil
from the filter before disposal. Never dispose
of oil by putting it in the trash or pouring it
on the ground, into sewers, or into streams
or bodies of water. Recycle it by taking it to
a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that indicates
when to change the engine oil and filter.
This is based on a combination of factors
which include engine revolutions, engine
temperature, and miles driven. Based on
driving conditions, the mileage at which an
oil change is indicated can vary
considerably. For the oil life system to work
properly, the system must be reset every
time the oil is changed.
This vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differentlythan a standard engine lubrication system
and requires a special procedure when
changing the engine oil and filter. See
Engine Oil
0237.
When the system has calculated that oil life
has been diminished, it indicates that an oil
change is necessary. A CHANGE ENGINE OIL
SOON message comes on. Change the oil as
soon as possible within the next 1 000 km
(600 mi). It is possible that, if driving under
the best conditions, the oil life system may
not indicate that an oil change is necessary
for up to a year. The engine oil and filter
must be changed at least once a year and,
at this time, the system must be reset. Your
dealer has trained service people who will
perform this work and reset the system.
It is also important to check the oil regularly
over the course of an oil drain interval and
keep it at the proper level.
If the system is ever reset accidentally, the
oil must be changed at 5 000 km (3,000 mi)
since the last oil change. Remember to reset
the oil life system whenever the oil is
changed.
How to Reset the Engine Oil Life System
Reset the system whenever the engine oil is
changed so that the system can calculate
the next engine oil change. To reset the
system: 1. Scroll through the DIC Info Pages menu until the remaining Engine Oil
percentage is displayed. See Driver
Information Center (DIC) 092.
2. Press and hold the thumbwheel on the DIC while the Oil Life display is active.
The oil life will change to 100%.
If the CHANGE ENGINE OIL SOON message
comes back on when the vehicle is started,
the engine oil life system has not reset.
Repeat the procedure.
