Driving and Operating
When in M (Manual Mode) a number
displays next to the M, indicating the
current gear that has been selected.
The number displayed in the gear
indicator 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.
Range Selection Mode controls the
vehicle and engine speed while
driving down a hill or towing a trailer,
by allowing you to select a desired
range of gears.
Grade Braking is not available when
the Range Selection Mode is active.
See
for more information.
While using the Range Selection
Mode, Cruise Control and the Tow/
Haul Mode can be used.
Tow/Haul Mode
The vehicle has a Tow/Haul Mode.
The Tow/Haul Mode adjusts the
transmission shift pattern to reduce
shift cycling, providing increased
performance, vehicle control, and
transmission cooling while driving
down steep hills or mountain
grades, towing, or hauling heavy
loads.
Press the button located on the end
of the shift lever to turn Tow/Haul on
or off. While Tow/Haul is on, a light
on the instrument panel cluster
comes on.
