CHEVROLET 2009 Suburban - Manual (Page 144)

Tow/Haul Mode
The vehicle has a Tow/Haul mode. The selector
button is located on the end of the column shift lever.
You can use this feature to assist when towing or
hauling a heavy load or if there is a need to charge a
battery installed in a trailer. See Towing a Trailer
on page 4-50 for more information.
When Tow/Haul mode is
selected the Tow/Haul
indicator light will come on.
The Tow/Haul mode works with the Autoride ® feature,
if the vehicle has this, to enhance the ride when
trailering or with a loaded vehicle. See Autoride
® on
page 4-50.
