Tow/Haul Mode (V6 Engine, Automatic
Transmission Equipped Models) (If Equipped)
The Tow/Haul Mode is a feature that assists when
pulling a heavy trailer. The purpose of the Tow/Haul
Mode is:
Reduce the frequency of shifts when pulling a
heavy trailer.
Provide the same shift feel when pulling a heavy
trailer as when the vehicle is unloaded.
Reduce the need to change throttle position when
pulling a heavy trailer.
This feature is turned on or
off by pressing a button on
the floor console. When the
feature is on, a light on the
instrument panel will
illuminate to indicate that
the Tow/Haul Mode has
been selected.See ªTow/Haul Mode Lightº in the Index. The
Tow/Haul Mode is automatically turned off each time
the vehicle is started.
The Tow/Haul Mode is most effective when the vehicle
and trailer combined weight is at least 75% of the Gross
Vehicle Weight Rating (GVWR) and the maximum
trailer weight rating for the vehicle. See ªGross Vehicle
Weight Ratingº and ªTrailer Weightº in the Index.
The Tow/Haul Mode for hauling a heavy trailer is most
useful under the following conditions
When driving through hilly terrain at speeds below
55 mph (88 km/h).
When driving in low speed or stop and go traffic
below 55 mph (88 km/h).
When driving in parking lots.
Use the Tow/Haul Mode instead of the previous
recommendation to shift to THIRD (3) gear to improve
fuel economy at highway speeds and shift performance
at lower speeds. Operating in the Tow/Haul Mode when
not pulling a heavy trailer will not cause damage to the
vehicle, but you may experience reduced fuel economy
and undesirable performance from the engine and
transmission. The Tow/Haul Mode should be used
only when pulling a heavy trailer.
