Hummer 2008 H2 - Manual (Page 117)

Driver Shift Control (DSC)
Your vehicle has a Driver
Shift Control (DSC).
The DSC controls the
vehicle’s transmission
and vehicle speed while
driving down hill or towing
a trailer by allowing you
to select a desired range
of gears.
To use this feature:
1. Move the shift lever to the MANUAL MODE (M).
This will force a downshift from the current gear,
for gears 3 through 6.
2. Press the (+) plus or (
−
) minus button on the left
side of the steering wheel, to select the desired
range of gears for your current driving conditions.
When in the MANUAL MODE (M) a number will display
next to the M, indicating the maximum available
gear. The DIC display will show the message MANUAL
SHIFT on the first line and the maximum available
gear will be displayed on the second line. See Driver
Information Center (DIC) on page 3-49 and DIC
Operation and Displays (Using DIC Buttons) on
page 3-49 or DIC Operation and Displays (Using Trip
Odometer Reset Stem) on page 3-54 for more
information. The number displayed in the DIC is the
highest gear available. The transmission will be limited
to the gear selected and lower gears. Shifting will
occur normally while driving, however the cluster will
continue to display the maximum available gear.
Higher gears will not be available unless the selection
is changed to include higher gears using the (+) plus
button.
Grade Braking is not available when the Driver Shift
Control is active. See Tow/Haul Mode on page 2-36 and
Towing a Trailer on page 4-55 for more information.
While using the DSC, cruise control and the tow/haul
mode can be used.
