Manual Transmission Operation - Chevrolet 2007 Silverado 1500 Pickup Owner's Manual

Cruise Grade Braking is available on the
®
6.6L DURAMAX diesel engine. Cruise Grade
Braking monitors a vehicle's cruise state, engine
torque, acceleration, vehicle speed, and the cruise
set speed. Using this information, it detects
when the truck is accelerating on a downhill grade
and will automatically downshift to slow the
vehicle if it exceeds the cruise set speed by a
certain amount.
See Cruise Control on page 217 for more
information.
The Tow/Haul mode and Grade Braking shift
modes can be activated by pressing the button on
the end of the shift control stalk. If your vehicle
®
has the DURAMAX diesel Engine or the
8.1L VORTEC™ gasoline engine, Grade Braking
is only available while the Tow/Haul Mode is
selected. While in the Range Selection Mode,
Grade Braking is deactivated allowing the driver to
select a desired range of gears.
See Automatic Transmission Operation on
page 140 for more information.
Also see Towing a Trailer on page 423 for more
information.

During the first 500 miles (805 km) of vehicle use,
start your vehicle moving in FIRST (1). This
allows clutch components to break-in properly.
Here is how to operate
your transmission.
