Conventional (fixed speed) cruise control
mode
This mode allows you to cruise at a desired speed over
about 45 km/h (28 mph) with your foot off the accelerator
pedal.
Cruising speed can be maintained, although a slight speed
change may occur when driving up or down a gradient, within

transmission is fixed in the normal position, regardless of the
position of the selector switch.
