Driving
WARNING: Hill descent mode does not provide hill hold at zero
mph (0 km/h). When stopped, the parking brake must be applied
and/or the vehicle must be placed in P (Park) or it may roll away.
Hill descent control requires a cooling down interval after a period of
sustained use. The amount of time that the feature can remain active
before cooling varies with conditions. The system will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.
Enabling hill descent control and setting the descent speed
1. Press and release the hill descent
button located on the floor console.
A light on the button will illuminate
and a one second chime will sound
when this feature is activated.
2. To increase descent speed, press the accelerator pedal until the
desired speed is reached.
3. To decrease descent speed, press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once the desired descent speed is
reached, remove your feet from the pedals and the chosen vehicle speed
will be maintained.
See Message center in your vehicle's owner guide for hill descent mode
messages.
