Driving and Operating
Cruise Grade Braking operates
while Cruise Control is engaged in
Tow/Haul Mode to assist in
maintaining vehicle speed under
loaded vehicle conditions. It utilizes
vehicle acceleration and deviation
from desired speed to determine the
correct gear for the operating
condition. If vehicle speed is above
the desired speed the transmission
will downshift to slow the vehicle.
If vehicle speed is near or below
desired speed, the transmission will
upshift, allowing vehicle speed to
increase.
While in the Range Selection Mode,
Cruise Grade Braking is not
available.
See
“
Range Selection Mode
”

Drive Systems
All-Wheel Drive
If the vehicle has this feature,
engine power is sent to all four
wheels when extra traction is
needed. This is like four-wheel
drive, but there is no separate lever
or switch to engage or disengage
the front axle. It is fully automatic,
and adjusts itself as needed for road
conditions.
Four-Wheel Drive
If the vehicle has Four-Wheel Drive,
you can send the engine's driving
power to all four wheels for extra
traction. To get the most satisfaction
out of Four-Wheel Drive, you must
be familiar with its operation.
Read the following before using
Four-Wheel Drive.
Notice:
Driving on clean, dry
pavement in Four-Wheel Drive
High or Four-Wheel Drive Low for
an extended period of time may
cause premature wear on the
vehicle's powertrain. Do not drive
on clean, dry pavement in
Four-Wheel Drive High or
Four-Wheel Drive Low for
extended periods of time.
While driving on clean, dry
pavement and during tight turns,
you may experience vibration in the
steering system.
If the vehicle has StabiliTrak
®
,
shifting into Four-Wheel Drive Low
will turn Traction Control and
StabiliTrak
®
off. See
