9-32 Driving and Operating
Cruise Grade Braking
(Six Speed Automatic
Transmission)
Cruise Grade Braking operates only
while Cruise Control is engaged in
Tow/Haul Mode. Cruise Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades in cruise control
by automatically shifting to lower
gears when the cruise set speed
is exceeded.
While in the Range Selection Mode,
Cruise Grade Braking is not
available.
See Manual Mode on page 9 ‑ 30 .
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.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that
helps prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
