Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness
of the hills. When going up steep
hills, you might want to step on
the accelerator pedal to maintain
the vehicle speed. When going
downhill, you might have to brake
or shift to a lower gear to keep the
vehicle's speed down. When the
brakes are applied the cruise control
is disengaged.
Cruise Control in Sport and
Manual Paddle Shift Gear
Selection
When the vehicle is in S (Sport)
and the manual paddle shift controls
are not being used, cruise control
operates in the same manner as
D (Drive).
When the vehicle is in S (Sport) and
the manual paddle shift controls are
being used, cruise control operates
as follows:
If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the
driver selected gear and will
not automatically up-shift or
down-shift the transmission
while the driver s gear selection
is active.
Driving and Operating
If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
up-shift or down-shift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select
D (Drive) on the gear range
selector for full automatic
transmission operation.
