STARTING AND DRIVING CAUTION D In the conventional (fixed speed) cruise control mode, an approach warning does not activate even if you are too close to the vehicle ahead, as neither the presence of the vehicle ahead nor the vehicle-to-vehicle distance is detected. Pay special attention to the distance between your vehicle and the vehicle ahead. Always confirm the setting in the multi-information display. D The conventional (fixed speed) cruise control mode of the dynamic radar/laser cruise control should not be used in the following conditions, which could result in serious injury or death. D To help maintain maximum control of your vehicle, do not use fixed speed control mode when using dynamic radar/laser cruise control while driving in heavy or varying traffic, or on slippery (rainy, icy or snow-covered) or winding roads. D Avoid vehicle speed increasing when driving downhill. If the vehicle speed is too fast in relation to the preset speed in the fixed speed control mode, cancel the fixed control mode and then downshift the transmission to use engine braking to slow down. (a) Turning the system on 31L334 To operate conventional cruise control mode, push the main switch. This turns the system on. The "CRUISE" indicator light in the instrument cluster comes on and "RADAR READY" appears on the multi-information display. Push the control lever in the "MODE" direction for longer than 1 second to change to conventional cruise control mode. The indicator on the multi-information display is as shown. You can now set your desired cruising speed. Pushing the main switch again will turn the system completely off and "CRUISE OFF" will appear in the multi-information display. However, once the vehicle-to-vehicle distance control mode activates and is used, it cannot be changed to the conventional (fixed speed) cruise control mode using the above operation. When the ignition switch is turned off, the main switch is also automatically turned off. To use the dynamic radar/laser cruise control again, push the main switch again to turn it on. 353
