STARTING AND DRIVING CAUTION To avoid accidentally engaging the cruise control, keep the "ON−OFF" button off when not using the dynamic laser cruise control. (c) Setting the desired speed Bring your vehicle to the desired speed, push the lever down in the "− SET" direction and release it. This sets the vehicle at that speed. At this time, the display indicates settings such as the preset vehicle speed, whether a vehicle is present ahead and selected vehicle−to−vehicle distance. If there is no vehicle detected ahead, the display does not indicate the vehicle ahead. You can now take your foot off the accelerator pedal. If you need to accelerate - for example, when passing - depress the accelerator pedal enough for the vehicle to exceed the preset speed. When you release the accelerator pedal, the vehicle will return to the control prior to acceleration. You cannot set a desired speed if the master warning light comes on, the alarm sounds and the display indicates one of the warning codes "E1", "E2" or "E3". If any of the above codes appears on the display, see "(l) Vehicle−to−vehicle distance control mode failure warning" on page 430. The transmission must be in "D" before you set the cruise control speed. 424
