GMC 2007 Savana - Manual (Page 268)

Tow/Haul Mode
Tow/haul is designed to assist while your vehicle
is pulling a large or heavy load or trailer.
Tow/haul is most useful while pulling such a load
in rolling terrain, in stop-and-go traffic, or when
you need improved low-speed control, such
as when parking. The purpose of the tow/haul
mode is to:
• Reduce the frequency and improve the
predictability of transmission shifts,
• provide the same solid shift feel when pulling
a heavy load as when the vehicle is unloaded,
• improve control of vehicle speed while
requiring less throttle pedal activity.
Press this button
located to the right of
the steering wheel
on the instrument panel
to turn tow/haul
mode on and off.
While activated, the
indicator light on the
instrument panel
will be on.
Tow/haul mode will turn off automatically when the
ignition is turned off. See Tow/Haul Mode Light
on page 185.
Tow/haul is most effective when the vehicle and
trailer combined weight is at least 75 percent of the
vehicle’s Gross Combined Weight Rating
(GCWR). See “Weight of the Trailer” later in this
section.
Driving with tow/haul activated without a heavy
load will cause reduced fuel economy and
unpleasant engine and transmission driving
characteristics, but will not cause damage.
