Tow/Haul Mode
Pressing this button at the
end of the shift lever turns
on and off the tow/
haul mode.
This indicator light on the
instrument panel cluster
comes on when the tow/
haul mode is on.
Tow/Haul is a feature that assists when pulling a heavy
trailer or a large or heavy load. See
Tow/Haul Mode on
page 3 ‑ 36 for more information.
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 the
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.
Operating the vehicle in Tow/Haul when lightly loaded
or with no trailer at all will not cause damage. However,
there is no benefit to the selection of Tow/Haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission
driving characteristics and reduced fuel economy. Tow/
Haul is recommended only when pulling a heavy trailer
or a large or heavy load.
