Tow/Haul – 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 grade. The amount of
downshift braking provided varies based
on the amount you press the brake pedal.
E295420
Deep Snow/Sand – For snow or
soft, dry sand.
E295413
Eco – For efficient driving. This
mode helps deliver maximum
fuel efficiency and helps to
increase driving range.
E295414
Slippery – For less than ideal
road conditions such as snow or
ice covered roads. Use this mode
for crossing terrain where loose, wet or
slippery material covers a firm surface.
Slippery mode lowers throttle response
and, if equipped with automatic
transmission, optimizes shifting for slippery
surfaces.
E225315
Rock Crawl – For optimum
rock-climbing ability. Rock crawl
mode prompts you to put your
vehicle in 4x4 Low. Rock Crawl mode
optimizes the throttle and transmission
response to provide you additional control
of your vehicle. See Using Four-Wheel
Drive (page 207).
