Automatic Engine Grade
Braking
Automatic Engine Grade Braking
assists when driving on a downhill
grade. It maintains vehicle speed by
automatically implementing a shift
schedule that uses the engine and
the transmission to slow the vehicle.
The system will automatically
command downshifts to reduce
vehicle speed, until the brake pedal
is no longer being pressed.
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.
See Automatic Transmission
Operation on page 2-24.
Parking Brake
To set the parking brake, hold the
regular brake pedal down, then push
the parking brake pedal down.
If the ignition is on, the brake system
warning light will come on. See
Brake System Warning Light
on page 3-36.
Notice: Driving with the parking
brake on can overheat the brake
system and cause premature wear
or damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
To release the parking brake, hold
the regular brake pedal down,
then push down momentarily on the
parking brake pedal until you feel
the pedal release. Slowly pull
your foot up off the park brake
pedal. If the parking brake is
not released when you begin to
drive, the brake system warning light
will be on and a chime will sound
warning you that the parking
brake is still on.
If you are towing a trailer and are
parking on a hill, see Towing a
Trailer on page 4-26.
