Tow/Haul Mode - GMC 2007 Acadia Owner's Manual

Tow/Haul Mode

Tow/Haul is a feature that assists when pulling a
heavy trailer or a large or heavy load. The purpose
of the Tow/Haul mode is to:
•
Reduce the frequency and improve the
predictability of transmission shifts when pulling
a heavy trailer or a large or heavy load.
•
Provide the same solid shift feel when pulling a
heavy trailer or a large or heavy load as when
the vehicle is unloaded.
•
Improve control of vehicle speed while requiring
less throttle pedal activity when pulling a heavy
trailer or a large or heavy load.
•
Increase the charging system voltage to assist
in recharging a battery installed in a trailer.
Press this button on
the console to
enable/disable the
tow/haul mode.
Tow/Haul may be turned off by pressing the
button again, at which time the indicator light on
the instrument panel will turn off. The vehicle
will automatically turn off Tow/Haul every time
it is started.
Tow/Haul is designed to be 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. Tow/Haul is most useful
under the following driving conditions:
•
When pulling a heavy trailer or a large or
heavy load through rolling terrain.
•
When pulling a heavy trailer or a large or
heavy load in stop and go traffic.
•
When pulling a heavy trailer or a large or heavy
load in busy parking lots where improved low
speed control of the vehicle is desired.
A light on the instrument
panel will come on to
indicate that tow/haul
mode has been
selected.
