The tow/haul feature:
• Moves upshifts to higher engine speeds
to reduce the frequency of
transmission shifting.
• Provides engine braking in all forward
gears, which will slow your vehicle and
assist you in controlling your vehicle
when descending a slope.
• Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle to help
control your vehicle speed when
descending a hill. The amount of
downshift braking provided varies
based upon the amount the brake
pedal is pressed.
The tow haul feature improves
transmission operation when towing a
trailer or a heavy load.
To deactivate the tow haul feature for
column shifter and return to normal driving
mode, press the button on the gearshift
lever twice. The indicator light deactivates
when the system turns off. Tow haul mode
also deactivates when you power down
your vehicle.
To deactivate the tow haul feature for
vehicles without a column shifter, cycle
through the available drive modes with the
drive modes button or rotary dial until tow
haul is selected and deactivate tow haul
mode. See Drive Control (page 251). The
indicator light deactivates when the
system turns off.
SelectShift™ Automatic
Transmission (If Equipped)
Your vehicle is equipped with a SelectShift
Automatic transmission. The SelectShift
Automatic transmission gives you the
ability to change gears up or down without
a clutch as desired.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically makes
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.
Note: Engine damage may occur if you
maintain excessive engine revving without
shifting.
E252861
The SelectShift Automatic transmission
feature has two modes: Progressive Range
Selection (PRS) and M mode.
Progressive Range Selection (PRS)
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with
an improved driving experience, for
example, in slippery conditions or when
experiencing a steep slope.
