TOW/HAUL - 4X4
E246592
For improved transmission
operation when towing a trailer
or a heavy load. This mode
moves upshifts to higher engine speeds to
reduce the frequency of transmission
shifting. This mode also provides engine
braking in all forward gears, which slows
your vehicle and assists you in controlling
your vehicle when descending a slope. The
amount of downshift braking provided
varies based on the amount you press the
brake pedal.
All four-wheel drive modes are selectable
in tow/haul mode. This mode does not
default to a certain four-wheel drive mode.
The system tunes the steering and
suspension to enhance driving comfort
when towing or carrying heavy loads.
The electronic locking differential is
available below 25 mph (40 km/h). See
