Manual Mode
Range Selection Mode
(Allison®Transmission or
Hydra-Matic®6-Speed
Transmission)
The vehicle may have a Range
Selection Mode. The Range
Selection Mode helps control
the vehicle's transmission and
vehicle speed while driving down
hill or towing a trailer by letting you
select a desired range of gears. To use this feature, do the following:
1. Move the shift lever to
M (Manual Mode).
2. Press the plus/minus buttons, located on the steering column
shift lever, to select the desired
range of gears for current driving
conditions.
When M (Manual Mode) is selected
a number displays next to the M,
indicating the current gear.
This number is the highest gear
that can be used. However, the
vehicle can automatically shift to
lower gears as it adjusts to driving
conditions. This means that all
gears below that number are
available. When 5 (Fifth) is selected,
1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle,
but 6 (Sixth) cannot be used until
the plus/minus button located on
the steering column lever is used
to change to the gear. Grade Braking is not available when
Range Selection Mode is active.
See
Tow/Haul Mode on page 9‑51.
While using Range Selection Mode,
Cruise Control and the Tow/Haul
Mode can be used.
If the vehicle has an exhaust
brake, it can also be used, but will
not automatically downshift the
transmission. See Exhaust Brake in
the Duramax Diesel supplement.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.

lock-up, indicated by trailer
wheel squeal or tire smoke
when a trailer wheel locks.
Trailer wheel lock-up may not
occur if towing a heavily loaded
trailer. In this case, adjust the
Trailer Gain to the highest
allowable setting for the towing
condition.
7. Re-adjust Trailer Gain any time vehicle loading, trailer loading or
road surface conditions change
or if trailer wheel lock-up is
noticed at any time while towing.

10-12 Vehicle Care
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not 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. For vehicles
without the CHANGE ENGINE OIL
SOON message, an oil change
is needed when the OIL LIFE
REMAINING percentage is near
0%. 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 miles)
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. Always reset the
engine oil life to 100% after every
oil change. It will not reset itself.
To reset the system on most
vehicles:
1. Display the OIL LIFEREMAINING on the DIC.
If the vehicle does not have
DIC buttons, the vehicle must
be in P (Park) to access this
display. See Driver Information
Center (DIC) on page 5‑33.
2. Press and hold the SET/RESET button on the DIC, or the
trip odometer reset stem
if the vehicle does not have
DIC buttons, for more than
five seconds. The oil life will
change to 100%. On all vehicles, the Engine Oil Life
System can be reset as follows:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. Display the OIL LIFE REMAINING on the DIC.
If the display shows 100%,
the system is reset. See Driver
Information Center (DIC) on
page 5‑33.
If the vehicle has a CHANGE
ENGINE OIL SOON message
and it comes back on when
the vehicle is started and/or the
OIL LIFE REMAINING is near 0%,
the engine oil life system has not
been reset. Repeat the procedure.
