Automatic Engine Grade Braking
Automatic Engine Grade Braking assists when driving
on a downhill grade. It maintains the vehicle’s speed by
automatically implementing a shift schedule that uses
the engine and the transmission to slow the vehicle.
This reduces wear on the brakes system and increases
control of the vehicle. The system constantly monitors
the vehicle’s speed, acceleration, throttle position,
and whether the brake pedal is being pressed, and
determines when to keep the current vehicle speed or to
slow down. The system will then automatically command
downshifts that reduces the vehicle’s speed, until the
brake pedal is no longer being pressed. This indicates
the desired vehicle speed has been reached.
While in the Electronic Range Select (ERS) mode,
grade braking is deactivated, allowing the driver to
select a range and limiting the highest gear available.
Grade braking is available for normal driving and in
Tow/Haul mode.

push down the parking
brake pedal down
with your left foot.
If the ignition is on, the brake system warning light will
come on. SeeBrake System Warning Light on
page 3-45.Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
